Not only kids of Tiger Moms go to Harvard.
Dawn Loggins of Lawndale, N.C. is on her way to Harvard, one of the eight world-famous universities in the eastern US. Nobody encouraged her to study or paid for her special classes. This girl created her own future.
The teen was abandoned by her family last summer, when her parents and two sisters moved to Tennessee. She found herself homeless and had to spend the night on friend's sofas.
The school bus driver learned about Dawn's situation and invited Dawn to move in with her family. Soon, Dawn had a job at Burns High School. She worked from 6 a.m. to 7:40 a.m. before the first school bell rang. She swept floors and picked up trash again in the afternoons, before diving into her studies in the evenings.
Dawn's hard work paid off. She finished school with a 3.9 GPA and scored 2,110 on the SAT.
"There were times when I felt like it would be easiest if I gave up," the
18-year-old said."But it was never in me to give up, because I realized that I was never going to be successful unless I got an education."
Even before Dawn's family left her, she led a difficult life. Her family was poor
and cups of noodles were often the only food. Dawn "studied by candlelight" because her parents couldn't afford to pay the electricity bill(电费).
Dawn has now reconnected with her family. They are proud of her accomplishments(成就) and are attending her high school graduation.
25. What does the underlined word "abandoned" mean in Chinese?
A. looked after
B. given up
C. worried about
D. thought of
26. Who helped Dawn when she found herself homeless?
A. Her teachers.
B. Her neighbors.
C. A Tiger Mom.
D. A school bus driver.
27. Which of the following words describes Dawn?
A. Open-minded.
B. Good-natured.
C. Strong-willed.
D. Warm-hearted
28. What is the best title for the text?
A. Another Harvard girl.
B. A girl in candle light.
C.The role of Tiger Moms.
D. From homeless to Harvard.

Does this situation seem familiar to you? Your English is progressing well, the grammar is now familiar, the reading comprehension is no problem, you are communicating quite fluently, but: Listening is STILL a problem! First of all, remember that you are not alone. Listening comprehension is probably the most difficult job for almost all learners of English as a foreign language. The most important thing is to listen as often as possible. The first step is to find listening resources. The Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia. The RealPlayer allows you to use the Internet like a radio station.
Once you have begun to listen on a regular basis, you might still be frustrated (懊恼) by limited understanding. What should you do?
Here is some of the advice I give my students:
●Accept the fact that you are not going to understand everything.
●Stay relaxed when you do not understand—even if you continue not to understand for a long time.
●Do not translate what you hear int o your native language.
●Listen for the general idea of the conversation. Don’t concentrate on detail until you have understood the main ideas.
I remember the problems I had in understanding spoken German when I first went to Germany. In the beginning, when I didn't understand a word, I insisted on translating it in my mind. This method usually resulted in confusion. Then, after the first six months, I discovered two very important facts. Firstly, translating creates a wall between the listener and the speaker. Secondly, most people repeat themselves constantly. By remaining calm, I noticed that —even if I didn’t pay much attention, I could usually understand what the speaker had said.
29.The best way to improve our listening is to _________ .
A. practise as much as possible
B. use the Internet like a radio station
C. find as many listening resources as possible
D. speak naturally and read as much as possible
30.Which of the following is a good habit when listening?
A. Try to understand everything.
B. Try to get the main ideas.
C. Pay much attention to details.
D. Translate each word in your mind.
31.Why did the writer mention his/her experience in Germany?
A. To prove the importance of translating.
B. To tell us the importance of staying calm.
C. To point out an ineffective method of listening.
D. To show the problems of speaking a foreign language.
D
Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging(包装) increased by 12% between 2010 and 2015. It
now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
32. What does the underlined phrase "over-consumption" refer to?
A. Using too much packaging
B. Recycling too many wastes
C. Making more products than necessary
D. Having more material than is needed
33. The author uses figures in Paragraph 2 to show .
A. the tendency of cutting household waste
B. the fact of packaging overuse
C. the rapid growth of super markets
D. the increase of packaging recycling
34. According to the text, recycling .
A. helps control the greenhouse effect
B. means burning packaging for energy
C. is the solution to gas shortage
D. leads to a waste of land
35. What can be inferred from Paragraph 4?
A. Unpackaged products are of bad quality
B. Supermarkets care more about packaging
C. Other products are better packaged than food
D. It is improper to judge quality
by packaging

Tips for cooking on a Tight Schedule From my experience, there are three main reasons why people don’t cook more often: ability, money and time. 36 Money is a topic I’ll save for another day. So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen. Here are three tips for great cooking on a tight schedule: Think ahead. The moments when I think cooking is a pain are when I’m already hungry and there is nothing ready to eat. So think about of the coming week. When will you have time to cook? Do you have the right materials ready? 37 Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread? 38 it takes around the same amount of time to make more of something. So save yourself the effort for a future meal.
39 This may surprise you, but one of the best tools for making cooking worth your time is experimentation. It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.
Hopefully that gives you a good start. 40 and don’t let a busy schedule discourage you from making some great changes in the way you eat and live!
A. Try new things.
B. Ability is easily improved.
C. Make three or four instead.
D. Understand your food better.
E. Cooking is a burden for many people.
F. Let cooking and living simply be a joy rather than a burden.
G. A little time planning ahead can save a lot of work later on.

高一下学期英语6月月考试卷 一、阅读理解 1. 阅读理解 Scientists used to explore on the surface of the ocean. Now they are exploring below the surface, too. They want to know about ocean water and the plant and animal life deep in the ocean. In 1934 the scientist William Beebe dived 3000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10330 feet In I960 his son Jean dived to a depth of 35800 feet. All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface. Gradually they succeeded. Cousteau, a Frenchman, was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week. Now scientists are developing even better equipment. With this new equipment, men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then, in 1964, he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate without help from the surface. Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a

Bibimbap Festival In the South Korean town of Jeonjuloves, their “mixed rice” dish is a hearty serve of rice topped with raw beef, a rainbow of vegetables, a raw egg and gochujang sauce so much. They take four days out of October to celebrate it. Like any festival there’s music, entertainment and magic, but making it that little bit different is the bibimbap that’s whipped (搅拌) up in a big bowl by dozens of chefs and served to over 400 people. 2. Waikiki Spam Jam Who knew this canned meat had so much love? Well, it turns out that a can of Spam is the go-to item in Hawaii, along with a grass skirt and garland (花环). The people of Hawaii love Spam so much that they even spend a day in May giving out the best Spam, a type of cheap canned meat made mainly from pork. 3. Bessieres Easter Egg Festival At Easter time, for those in the French town of Bessieres it’s all about an egg far less sweet. Here they celebrate the holiday by getting dozens of chefs to make one large omelette (煎蛋卷) ---15,000 eggs strong --- for the townsfolk (市民). 4. Potato Days Festival

重庆市铜梁县第一中学物理第十一章 电路及其应用精选测试卷
重庆市铜梁县第一中学物理第十一章 电路及其应用精选测试卷 一、第十一章 电路及其应用选择题易错题培优（难） 1．用两个相同的小量程电流表，分别改装成了两个量程不同的大量程电流表1A 、2A ，若把1A 、2A 分别采用并联或串联的方式接入电路，如图所示，则闭合电键后，下列有关电表的示数和电表指针偏转角度的说法正确的是 A ．图甲中的1A 、2A 的示数相同 B ．图甲中的1A 、2A 的指针偏角相同 C ．图乙中的1A 、2A 的示数和偏角都不同 D ．图乙中的1A 、2A 的指针偏角相同 【答案】B 【解析】 【详解】 AB.图甲中的A 1、A 2并联，表头的电压相等，电流相等，指针偏转的角度相同，量程不同的电流表读数不同，故A 错误，B 正确； CD.图乙中的A 1、A 2串联，A 1、A 2的示数相同，由于量程不同，内阻不同，电表两端的电压不同，流过表头的电流不同，指针偏转的角度不同，故CD 错误。 2．如图所示，三个定值电阻R 1、R 2、R 3的电阻值均不相等，在A 、B 之间接一个电源，在C 、D 之间接一个电流表，电流表的示数为I ．现将电源、电流表的位置互调，则电流表的示数（ ） A ．可能增大 B ．可能减小 C ．一定不变 D ．由于R 1、R 2、R 3大小关系不知，故无法判定 【答案】C 【解析】 两种情况下的电路连接如图所示：
设电源电压为U =6V ，R 1=3Ω，R 2=2Ω，R 3=6 Ω，在甲图中 23 23 = 1.5R R R R R ?=Ω+甲并， 112==1U R U R 甲并甲并，1=6V 2V 33 U U =?=甲并，电流表的示数为32V 1 =A 63U I R ==Ω甲并甲，在乙图中 12 12= 1.2R R R R R ?=Ω+乙并，335==1U R U R 乙并乙并，1=6V 1V 66 U U =?=乙并，电流表 的示数为11V 1 =A 33 U I R 乙并乙==Ω，故两次示数相同，则选C ． 【点睛】在A 、B 之间接一个电源，假设A 端为正极，在C 、D 之间接一个电流表时，通过电流表的电流通路是：A----R 1----电流表----R 3----B 电路中的电阻是 R 1+R 3；将电源、电流表的地位互调，假设D 端为正极，通过电流表的电流通路是：D----R 1----电流表----R 3----C 电路中的电阻是R 1+R 3．电路的电源不变，电阻不变，故电流一定不变． 3．如图所示的部分电路中，已知I ＝3 A ，I 1＝2 A ，R 1＝10 Ω，R 2＝5 Ω，R 3＝30 Ω，则通过电流表的电流大小和方向是( ) A ．0.5 A ，向右 B ．0.5 A ，向左 C ．1 A ，向右 D ．1 A ，向左 【答案】A 【解析】 【详解】 对于稳恒电路中的某一节点，流入的电流总和一定等于流出的电流总和．对于节点c ，已知流入的电流I ＝3 A ，流出的电流I 1＝2 A ，则还有1 A 的电流要流出节点c ，由此可知经过R 2的电流I 2＝1 A 向右．根据欧姆定律， U 1＝I 1R 1＝20 V U 2＝I 2R 2＝5 V 电压等于电势之差 U 1＝φc －φa U 2＝φc －φb 两式相减可得 φb －φa ＝15 V 即b 点电势比a 点高15 V ，则通过R 3的电流 33 0.5A b a φφI R -= =
