Ⅰ.阅读理解

A

If your kitchen is home to just one type of cooking oil，you are missing out.As well as their unique tastes，different oils have different properties.Here's a summary of cooking techniques and which widely available oil suits each best：

FOR GRILLING，BROWNING，AND DEEP-FRYING

Almond(杏仁) oil is a member of the healthy monounsaturated (单一不饱和的) fat group, along with olive and macadamia nut oil.It has a high smoke point (450 ℃)，so it can be used for all kinds of cooking and add that all-important extra nutty flavor.Store in a cool dry place.

FOR BAKING AND STIR-FRYING

Macadamia nut oil gives any dish a rich buttery flavor and is full of antioxidants(抗氧化剂) and monounsaturated fats.It can tolerate up to 230 ℃ and will last up to three years if stored in a dry，cool place.

FOR LIGHT COOKING，SAUCES，AND LOW-HEAT BAKING

Sesame (芝麻) oil is often described as the queen of oils and is widely used as a cooking oil in India and a flavor enhancer in Chinese and Southeast Asian cuisine.Unlike some cooking oils，sesame oil is delicate and will spoil after only a few months.Always store in the refrigerator. FOR COLD SALAD DRESSINGS，DIPS AND MARINADES

Extra virgin olive oil is one of the world's healthiest foods and loaded with flavor，which will vary depending on where the olives are grown.If stored in a dark bottle away from light and heat，extra virgin olive oil can last up to 12 months.

[语篇解读]本文为一篇说明文。主要介绍了几种常见的烹饪方法及与之相匹配的食用油。1．What is the best title of the passage?

A．Which oil is your choice?

B．How to buy oil?

C．How to cook?

D．Which cooking technique is the best?

解析：标题归纳题。根据第一段最后两句可知本文的主题是，不同的烹饪方式需使用不同的食用油，故答案为A项。

答案：D

B

The rumor proved all too bitterly true：Park's Hardware, a downtown institution of Orono for over 100 years，would be closing.Locals cross-examined，and begged Lin，the owner of the store，but in vain.Running a small，local，family-owned hardware business was no longer profit-making.The town's affection for Park's Hardware was just not enough to allow it to compete against the giant warehouse stores.

I was one member of the excited masses that began to walk through Park's as，day by day，the lettering on the front window changed from “20% OFF EVERYTHING” to “30%”，“40%”，and on and on，until the only things left were the light sockets (插座) and doorknobs. Compared with giant warehouses，a hardware store is special.I recall the time I was exploring in one giant warehouse for a wireless doorbell that Park's didn't carry.I found the thing，but didn't understand the following note on the package: “Red light indicates condition of the battery.”“Excuse me，”I said to a clerk，holding the item out，“I can't seem to find the red light.”The man examined it, and said, “Neither can I．”I contrasted this experience with one I routinely had at Park's.“Lin，”I'd beg.“Can you...please...I don't know...do you think...？”And quicker than one could say，“little red light，”Lin would spring into action and together we'd sit down to find the solution.

I could buy a single screw (螺丝钉) at Park's.At a warehouse I have no choice but to buy a box of a hundred screws.But I don't want a box of a hundred screws when all I need is one. I just want

to know the location of the little red light，and now that Park's is gone，I realize that I never will. [语篇解读]本文为一篇记叙文，涉及家庭、朋友与周围的人的话题。讲述了一家五金店的倒闭和人们对它的怀念的一些情况。

4．Why did Park's decide to stop its business?

A．The owner invested in other business.

B．The owner couldn't make enough money.

C．Its location was not convenient for shopping.

D．It couldn't win enough affection from the locals.

解析：细节理解题。根据第一段中的“Running a small，local，family-owned hardware business was no longer profit-making.The town's affection for Park's Hardware was just not enough to allow it to compete against the giant warehouse stores.”可知，经营这样的五金店已经不能够挣钱了，镇上的人们对这家五金店的喜爱并不能使它赢得与大型仓储式商店的竞争。故选B。答案：B

5．What did Park's do before closing?

A．It had a closing down sale.

B．It struggled for its reorganization.

C．It distributed its goods to regulars.

D．It looked for a new owner.

解析：细节理解题。根据第二段中的“the lettering on the front window changed from‘20% OFF EVERYTHING’to‘30%’，‘40%’”可知，五金店在关门息业之前采取了加大力度打折促销的方式，即清仓大处理。故选A。

答案：A

6．What does the writer's experience in Paragraph 3 indicate?

A．The benefit of having more choices.

B．The pressure of competition for Park's.

C．The good service of Park's.

D．The responsible working attitude of large stores.

解析：根据第三段中的“The man examined it，and said，‘Neither can I．’”以及“Lin would spring into action and together we'd sit down to find the solution.”可知，作者提及自己购买无线门铃的经历是为了说明这家大型商店和帕克的五金店在服务质量方面存在的差别，借以突出帕克的五金店良好的服务。故选C。

答案：C

7．What's the writer's tone in writing this passage?

A．Humorous.B．Supportive.

C．Critical. D．Regretful.

解析：推理判断题。从文章开始到文章结束，作者在字里行间都描述了自己和其他人对镇上一家五金店关门的惋惜之情。故选D。

答案：D

Ⅱ.阅读七选五

Although people value intelligence—understanding，reasoning，the ability to learn—they also respect wisdom，or the knowledge and experience that they gain over a lifetime.In some ways，wisdom is like beauty: we value it，we desire it，we know it when we see it，but it is nearly impossible to pin down such a nice quality.1

1．Working at being social.

Studies show that people who stay connected with others show higher levels of wisdom than those who remain alone.2Next time you're at a party or gathering，single out someone who's standing alone and strike up a conversation.

2．3

Wisdom involves being able to understand all sides of an issue without letting personal feelings get in the way.Opening your mind means realizing that everyone has a life story that influences their actions.During the course of every day，make a note of the issues that annoy you，and take a moment to see them from the other side.

3．Learning how to say “I could be wrong”．

A wise person understands that it is impossible to know everything and that life is likely to take unexpected turns.4Admitting that there are times when you could be mistaken will go a long way towards strengthening your fame.

4．Reading the news.

5If you haven't already read a daily paper or news online，start by going through a single front-page article from a major respected news source.

Almost everyone has the potential to become wiser，particularly if you strengthen these habits. A．Practicing being open-minded.

B．Sharing good news with your friends.

C．But researchers have tried and here are what they've found.

D．Recognizing your errors can lead only to even greater wisdom.

E．Make an effort to join a new club，or invite an old friend for coffee.

F．You do not have to admit your mistakes if you are really unwilling to.

G．You cannot make balanced choices unless you unde-rstand world circumstances.

答案：1.C 2.E 3.A 4.D 5.G

Ⅲ.语法填空

Ⅰ.阅读理解

A

People love cellphones，which is why nine in ten Americans own one.But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years.A new study in rats now_augments those concerns.Its data linked long-term，intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.The results have yet to be confirmed，the authors note.

Indeed，although the rat study found a link between cellphone radiation and cancer，it offers no clues to why such a link might exist，notes Jonathan Samet.He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles.Still，he calls the new study's findings “significant”．They could lead to studies researching how cellphone radiation might cause cancer，he says.

Phone signals are relayed between cell towers and cellphones via radio waves.This radio frequency—or RF—radiation is a type known as non-ionizing(非电离的)．Unlike X-rays，non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules，producing ions. So it tends to be far less harmful than ionizing radiation，such as X-rays.But that does not mean radio waves might not cause harm.

In very large doses(量) this radiation will heat the body and cause tissue damage.But it's not yet

known what much lower RF levels might do，such as those from cellphone use.Five years ago，the World Health Organization's International Agency for Research on Cancer，or IARC，concluded that cellphone use “is possibly carcinogenic (致癌的)”．

Its conclusion was based on what little research data was available at that time.But notice that IARC was not certain.It said only that phone use might “possibly” cause cancer.So scientists at the National Toxicology Program，or NTP，investigated further.

[语篇解读]本文是一篇说明文。人们喜欢用手机，90%的美国人都有手机。那么，过度使用手机是否会有患癌的风险呢？一项新的研究给出了一些线索。

1．Which of the following can replace the underlined word “augments”？

A．figures out B．puts out

C．refers to D．adds to

解析：词义猜测题。画线词前面提到过度使用手机是否有患癌的风险这一问题多年来引发的争议不断，再根据画线词后的“concerns”和“Its data linked long-term，intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.”可知，现在一项在老鼠身上进行的新研究增加了那些忧虑。故画线词与adds to意义相近。

答案：D

2．In which aspect does Jonathan Samet think the new study in rats is significant?

A．It assists him with his teaching.

B．It indicates a new research direction.

C．It warns people to mind cellphone safety.

D．It makes a breakthrough in cancer research.

解析：推理判断题。根据第二段中的“They could lead to studies researching how cellphone radiation might cause cancer，he says.”可知，这项研究会促使科学家去查明手机辐射可能是怎样致癌的，也就是说它为科学家提供了一个新的研究方向。

答案：B

3．What is Paragraph 3 mainly about?

A．How phone signals are delivered.

B．How cellphones produce radiation.

C．Features of radiation from cellphones.

D．Differences between ionizing and non-ionizing radiation.

解析：段落大意题。根据第三段的内容尤其是“non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules，producing ions. So it tends to be far less harmful than ionizing radiation...”可知，本段主要讲的是手机辐射的特点，它是非电离的，其危害性远低于电离辐射。

答案：C

4．What might be the theme of NTP scientists' further research?

A．Why cellphone use causes cancer.

B．Whether cellphone use really causes cancer.

C．What health effects cellphone use has.

D．How much exposure to cellphone radiation is safe.

解析：推理判断题。根据最后一段中的“It said only that phone use might ‘possibly’ cause cancer.So scientists at the National Toxicology Program，or NTP，investigated further.”可知，NTP的科学家进一步研究的主题可能是手机使用是否真的会导致癌症。

答案：B

B

Ambar presses her hand to her forehead as she considers the question on her screen: how many sevens in 91? The ten-year-old has been struggling with it for about a minute when she smiles，“13！” Her tutor responds by posting a large smiling cat picture on her screen—the virtual(虚拟的) meaning of a pat on the back.He is sitting on the other side of the world in an online tutoring centre in India.

Ambar，who attends Pakeman Primary School in London，is one of nearly 4,000 primary school children in Britain that have signed up for weekly one-to-one maths sessions with tutors based in India and Sri Lanka.The lessons，provided by a company called Third Space Learning，are targeted at pupils struggling with maths—particularly those from disadvantaged backgrounds.

From next year，the platform will become one of the first examples of artificial intelligence (AI) software being used to monitor，and ideally improve teaching.Together with some British scientists，the company has analysed around 100,000 hours of audio and written data from its tutorials(辅导课)，with the goal of identifying what makes a good teacher and a successful lesson. Tom Hooper，the company's CEO，said，“We've recorded every lesson that we've ever done.By using the data，we've been trying to introduce AI to improve the teaching.”But he argued that the aim is not to replace teachers with robots.“There's a slightly dubious(不确定的) conversation about how AI will make humans irrelevant，but it's not at all about replacing humans，”he said.“Our whole belief is that for children not doing well in the subject，people are what matters.”

Pupils on the program have a 45-minute session with the same tutor each week.They communicate through a headset and a shared “whiteboard”．The lessons at Pakeman Primary School are tailored to the individual，including visual rewards linked to the child's interests.In addition to the raw audio data，each lesson has various success metrics attached：how many problems are completed，how useful the pupil finds the session，how the tutor rates it.

[语篇解读]本文是一篇说明文。数学成绩不好怎么办？没关系。坐在家里，你就可以享受高科技公司Third Space Learning为你提供的一对一网上教学服务。

5．Why does the author mention Ambar in the beginning?

A．To praise her tutor.

B．To show her struggle with maths.

C．To introduce a company.

D．To encourage pupils to learn maths online.

解析：推理判断题。第一段提到了Ambar在网上接受一对一的数学教学，该网上家教中心位于世界的另一端——印度。由此引出下文介绍的一家公司Third Space Learning。故作者在文章一开始提到Ambar是为了引出这家公司。

答案：C

6．What do we know about Third Space Learning?

A．It makes good teachers and lessons.

B．It is aimed at students from poor backgrounds.

C．It is being used to monitor and improve teaching.

D．It provides online maths lessons for schoolchildren.

解析：推理判断题。根据第二段中的“signed up for weekly one-to-one maths sessions with tutors based in India and Sri Lanka...are targeted at pupils struggling with maths”可知，Third Space Learning为小学生提供网上一对一的数学课程，故选D项。

答案：D

7．Which may Tom Hooper agree with?

A．AI makes humans irrelevant.

B．AI is beneficial to teaching.

C．Robots are smarter than humans.

D．Robots will replace humans.

解析：推理判断题。根据第四段中的“By using the data，we've been trying to introduce AI to improve the teaching.”可知，Hooper认为AI对教学是有好处的，故选B项。

答案：B

8．What is the last paragraph mainly about?

A．What is taught in the lesson?

B．How is the lesson taught?

C．Who learns the lesson?

D．Why is the lesson taught?

解析：段落大意题。根据最后一段的内容可知，本段主要介绍了这种课的教学模式。故选B

项。

答案：B

Ⅱ.完形填空

[语篇解读]作者用诙谐的语气质问Wi-Fi，这呈现了现代人的一种通病，那就是对无线网络的依赖。

1．A.Now that B．Only if

C．Though D．When

解析：根据语境可知，虽然(Though)作者知道Wi-Fi帮助了自己，但是正是Wi-Fi的特殊作用让作者在做事情的时候会分心。

答案：C

2．A.praised B．increased

C．focused D．divided

解析：参见上题解析。

答案：D

3．A.keep in B．bring back

back“使回忆起，使想起”；approve of“同意，赞成”；give up“放弃”。

答案：A

4．A.drawing B．pushing

C．forcing D．observing

解析：根据语境可知，此处形象生动地表现了作者不能抗拒Wi-Fi对自己的吸引。draw“吸引”符合语境。push“推，催促”；force“强迫，迫使”；observe“观察”。

答案：A

5．A.space B．soul

C．society D．workplace

解析：Wi-Fi进入了作者的家和灵魂中。下文中的“holds our mind”是关键提示。

答案：B

6．A.entertainment B．argument

C．expansion D．struggle

解析：Wi-Fi(本来)只是我们娱乐(entertainment)和获取信息的窗口。argument“争论”；expansion“扩张”；struggle“斗争，奋斗”。

答案：A

7．A.strict B．satisfied

C．generous D．busy

解析：根据上文的“You're just a window for https://www.wendangku.net/doc/aa12190231.html,rmation.”以及“But”所表示的转折关系可知，此处表示人们并不满足于(satisfied)Wi-Fi仅仅是个“窗口(window)”。strict“严格的”；generous“慷慨的”；busy“繁忙的”。

答案：B

8．A.thoughts B．eyes

C．exits D．doors

解析：此处表示人们将Wi-Fi的作用扩大化，不仅仅满足于其作为窗口的作用，而是将所有的“门(doors)”打开迎接Wi-Fi。某种程度上而言，door是window的“升级版”。

答案：D

9．A.disease B．inspiration

C．routine D．phenomenon

解析：结合下文中的“an illness”可知，作者疑惑的是自己和其他人对Wi-Fi如此依赖的现象是否是一种病(disease)。inspiration“灵感”；routine“惯例”；phenomenon“现象”。

答案：A

10．A.recommend B．instruct

C．commit D．adapt

解析：如果对Wi-Fi的情感是一种依赖的话，Wi-Fi能保证与作者一生都亲密无间吗？commit 意为“保证(做某事、遵守协议或遵从安排等)，承诺”，符合语境。recommend“推荐”；instruct“教导”；adapt“适应”。

答案：C

11．A.persist B．relax

解析：Wi-Fi不能给自己放几天假以便它和作者都能放松(relax)一下吗？persist“坚持”；progress“行进”；balance“平衡”。

答案：B

12．A.raw B．ambiguous

C．strong D．fast

解析：根据本句中的“not a slow one”可知，Wi-Fi并不是慢性毒药，而是快速起效的毒药，故用fast与slow形成对比。raw“不熟练的”；ambiguous“含糊不清的”；strong“强壮的”。答案：D

13．A.to B．against

C．from D．within

解析：Wi-Fi是一种能控制人们的思想并使人们随着它的音调起舞的毒药。to表示“随着”。答案：A

14．A.affordable B．valuable

C．conventional D．attractive

解析：根据下文中的“anyone can buy”可知，如今Wi-Fi的价格是如此低廉以至于任何人都能买到，并使其成为人们的伴侣。affordable“支付得起的，不算太贵的”；valuable“有价值的”；conventional“传统的”；attractive“有吸引力的”。

答案：A

15．A.addition B．expert

C．companion D．instrument

解析：参见上题解析。下文中的“Because you accompany us everywhere and never let us be alone.”亦是提示。addition“添加物”；expert“专家”；companion“伴侣，伙伴”；instrument“工具”。

答案：C

16．A.sometimes B．always

C．never D．seldom

解析：毫无生命的Wi-Fi是决不会在意其用户的健康的，但是用户们会一直担心Wi-Fi的“健康”，此处用always与上文的“never”形成对比，强调人们对Wi-Fi的在意程度。

17．A.selfish B．dishonest

C．responsible D．real

解析：根据下文中的“person made of flesh and blood(血肉之躯)”可知，作者想知道如果Wi-Fi成为拥有血肉之躯的真实的人，人们是否会一样喜欢它。selfish“自私的”；dishonest“不诚实的”；responsible“负责任的”；real“真实的”。

答案：D

18．A.control B．scold

C．comfort D．challenge

解析：根据上文作者介绍的人们对Wi-Fi的依赖及下文中的“we even can't get rid of you”可知，人们离开了Wi-Fi简直无法生活下去，而本句中的“with your numerous talents”正是Wi-Fi 控制人们的方式。control “控制”；scold“责备”；comfort“安慰”；challenge“挑战”。答案：A

19．A.friends B．slaves

C．colleagues D．employers

解析：根据语境可知，Wi-Fi控制了人们，也就是说人们成了被其掌控的奴隶(slaves)。friend“朋友”；colleague“同事”；employer“雇主”。

答案：B

20．A.suffered B．connected

C．survived D．surfed

解析：根据语境尤其是本句中的“in the previous generations”可知，作者非常疑惑的是在早期没有Wi-Fi的时候人们是如何存活(survived)下来的。suffer“受苦”；connect“联系”；surf“冲浪”。

北师大版高中英语必修一unit1 lesson4 City and Country

Lifestyles City and Country Part A Reading: City and Country Before you start 1. Answer these questions to prepare yourself. Use the Key Words below to help you. (1)How are city and countyr lifestyles different in China? (2)Can you imagine city and country lifestyles in Britain? 2. Guess what the two articles are about. Read to learn 3. Now read the two texts quickly and check your guesses. City and country Debbie is an accountant in a large company in the centre of London. I need to be in my office by nine o’clock so I usually get up at seven o’clock. I travel to work on “the tube”. That’s what people call the underground in London. It takes about fifty minutes. Usually, it’s s o crowded that I can’t find anywhere to sit. I just stand. I’m always tired before I arrive at work. I don’t like the underground! I spend all morning checking numbers. Lunch is always simple. I often get a sandwich in a nearby sandwich shop or I just have some biscuits and a cup of coffee. Then in the afternoon, I return to the paperwork in the office. On Monday nights, I have dance classes, and on Wednesday nights, I go to the gym. I need to do that because I don’t get enough exercise otherwise. On Tuesday and Thursday nights, I have French classes. I work for a French company so I think studying French will help me in my job.

伊莱亚斯的故事 我叫伊莱亚斯。我是南非一个穷苦的黑人工人。第一次见到纳尔逊曼德拉的时候，是我一生中非常艰难的时期。当时我才12岁。那是在1952年，曼德拉是我寻求建议的黑人律师。他为黑人提供法律问题上的指导。他对此从不吝惜自己的时间，在这一点上我很感激他。 我需要他的帮助是因为我只受到很少的教育。我六岁开始上学。学校离家有3英里远，我仅仅在那里读了两年。我不得不辍学，因为我的家庭无法支付学费和交通费。我既不会读，也不会写。几经周折，我才在一家金矿找到工作。可是那个时候你想要住在约翰内斯堡就非得要有身份证不可。非常遗憾的是我没有这个证件，因为我不是在那里出生的，我很担心我会不会失业。 有纳尔逊曼德拉帮助的日子是我一生中最快乐的时光。他告诉我要在约翰内斯堡站住脚，应当如何获取证件。我对自己的未来更充满了信心。我永远不会忘记曼德拉多么善良。当他组织了非国大青年联盟时， 我立即加入了这个组织。他说:“过去30年来所出现的许多法律剥夺了我们的权利，阻挡了我们的进步，一直到今天我们还处在几乎什么权利都没有的阶段。”他说的是真话。当时黑人不能选举或选择他们的领导人。他们不能做自己想做的工作。他们在城里的住宅区都是由白人决定的。他们被打发去居住的城镇之外的地方是南非最贫穷的地区。在那儿没有人能够种庄稼。事实上就像纳尔逊曼德拉所说的： “……我们被置于这样一个境地：我们要么被迫接受低人一等的现实，要么跟政府斗争。我们选择向法律进攻。首先我们以和平的方式来打破法律法规，而当这种方式也得不到允许时……只有到这个时候，我们才决定用暴力反抗暴力。”事实上，我并不喜欢暴力……但在1963年的时候，我帮助他炸毁了一些政府大楼。那是很危险的事情，因为如果我被抓住了，可能要做几年牢。但是我乐于帮忙，因为我知道，这有助于实现我们黑人和白人平等的梦想

Unit 5 ELIAS` STORY My name is Elias.I am a poor black worker in South Africa.The time when I first met Nelson Mandela was a very difficult period of my life.I was twelve years old. It was in 1952 and Mandela was the black lawyer to whom I went for advice. He offered guidance to poor black people on their legal problems.He was generous with his time, for which I was grateful. I needed his help because I had very little education.I began school at six. The school where I studied for only two years was three kilometers away.I had to leave because my family could not continue to pay the school fees and the bus fare. I could not read or write well.After trying hard,I got a job in a gold mine.However,this was a time when one had got to have a passbook to live in Johannesburg.Sadly I did not have it because I was not born there, and I worried about whether I would become out of work. The day when Nelson Mandela helped me was one of my happiest.He told me how to get the correct papers so I could stay in Johannesburg.I became more hopeful about my future.I never forgot how kind Mandela was.When he organized the ANC Youth League, I joined it as soon as I could.He said:"The last thirty years have seen the greatest number of laws stopping our rights and progress, until today we have reached a stage where we have almost no rights at all.” It was the truth.Black people could not vote or choose their leaders.They could not get the jobs they wanted. The parts of town in which they had to live were decided by white people.The places outside the towns where they were sent to live were the poorest parts of South Africa. No one could grow food there .In fact as Nelson Mandela said:“…we were put into a position in which we had either to accept we were less important or fight the government. We chose to attack the laws.We first broke the law in a way which was peaceful; when this was not allowed…only then did we decide to answer violence with violence.…… As a matter of fact, I do not like violence…but in 1963 I helped him blow up some government buildings.It was very dangerous because if I was caught I could be put in prison.But I was happy to help because I knew it would help us achieve our dream of making black and white people equal.
