第二部分阅读理解（共15小题；每小题2分，满分30分）

A

In 2006, Sal Khan launched “Khan Academy” to provide YouTube teaching for his 12-year-old cousin who needed help with maths. The online school now provides more than 580 million online lessons in over 36 languages. Last fall, Khan created a physical school in California.

The Khan Lab School runs differently from traditional schools. There’s no homework or grades, and students — ranging from ages five to 12 —share the same classroom. “It’s only 150 years that we separated children by age in classrooms,” said Khan. “The idea is that you can learn a lot

from the students who are a little older than you and if you’re 12 ye ars old you could exercise a lot of leadership being a teacher assistant for the younger students.”

The school also breaks up the students based on their “independence level,” rather than their age. “Whatever independence level you’re on — whether in math, reading or writing —you’re on your own track,” he explained.

Another unique feature of the school is that it runs all day, all-year long. Khan said the problem with the current school schedule is that they do not have enough learning time. “The gap betwe en the U.S. and Shanghai test scores can be explained by time in the classroom,” Khan said. “You have the summer learning loss, which is not only time that you’re not learning when you could be, but also you’re forgetting the things that you learned at the end of last year.”

Now Khan Lab School enters its second year. Khan said he hopes to use the reach of the Khan Academy, which has more than 30 million users now, to send students and teachers in other schools information on how to create similar learning experiences in their classrooms.

6. Last fall, Sal Khan ________.

A. launched an online course

B. set up The Khan Lab School

C. helped his cousin with maths

D. started Khan Academy on the Internet

7. Which is one of the features of the Khan Lab School?

A. Kids are separated by ages.

B. Kids are trained to be teachers.

C. Younger kids learn from older ones.

D. Older kids learn less than younger ones.

8. What can be inferred from Paragraph Four?

A. Students in America spend little time at school.

B. American schools run all day, all-year long.

C. Learning time is very important for test scores.

D. Summer is the best time for learning.

9. According to the last paragraph, Khan is going to ________.

A. share the school’s experience

B. att ract more students

C. create more similar schools

D. hire more teachers

B

In the years of my growing up, Dad was hard on me. He made sure I made my bed and did my homework. As a school girl and young adult, I feared him and felt bitter about him. He seemed

unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

He would call in advance to make sure there was no alcohol at the party. I got so angry with him for laying down the law. I would scream, “I hate you!” Dad would yell back, “Good! I don’t care!” Deep down I knew he did.

One time at a party, I drank too much alcohol and got so sick. I said, “Call my dad.” Next thing, Dad was carrying me to the car. I woke up the next morning, thinking I would definitely be criticized. As expected, I got a roasting, but I now understand why I need discipline.

Dad was 29 when he got his big roles in films. I had an early start at the age of nine with a role in a 1990s TV series, but it wasn’t until I finished film studies that I pursued my career as an actress. Like those early days for Dad, I faced lots of rejections. Working in such a competitive industry, I’ve sometimes thought, “I can’t do this any more.”

Once, after a trip to Hollywood, I returned to Australia so depressed and spent months in my bedroom painting, listening to Eckhart Tolle’s music an d trying to find myself again. Dad sat me down and said,“Alice, I know it’s hard, but it’s all about persistence(坚持不懈).”

Now I get to work with Dad a lot, which I love. We are both enthusiastic about acting, which comes from us being so interested in people. If it weren’t for Dad, I wouldn’t be where I am today. He’s my biggest fan, and when you have that in your lif e you can go a long way.

10. Which of the following is similar in meaning to the underlined part?

A. I was blamed.

B. I was pulled out of bed.

C. I got out of trouble.

D. I was comforted.

11. What can we learn from the passage?

A. As an actor, her father’s career is always smooth.

B. It is her father who has helped shape the author who she is.

C. She would feel tired when going out with her father on weekends.

D. She was bitter about her father as a school girl as he was too proud of himself.

12. Which of the following best describes the writer’s father?

A. Severe and impatient.

B. Talkative and hard-working.

C. Proud but gentle.

D. Strict but caring.

C

Findings from a new study were presented at a recent meeting of the American Psychosomatic(身心的) Society. Researchers in the United States studied 100,000 women during an eight-year period, beginning in 1994. All of the women were fifty or older. The study was part of the Women’s Health Initiative organized by the National Institutes of Health.

The women were asked questions measuring their beliefs or ideas about the future. The researchers attempted to identify each woman’s personality eight years after gathering the information.

The study found that hopeful individuals were 14% less likely than other women to have died from any cause. The hopeful women were also 30% less likely to have died from heart disease after the eight years.

Hilary Tindle from the University of Pittsburgh in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.

The researchers also gathered information about people’s education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period.

Some women who answered the questions were found to be hostile (怀敌意的), or highly untrusting of others. These women were 16% more likely to die than the others. They also were 23% more likely to die of cancer.

The study also found women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely not to exercise.

Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person’s physical health. She also says the study does not prove that negative emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.

13. In which part of a newspaper can you read the above passage?

A. Nation

B. Opinion

C. Science

D. Business

14. Researchers carry out the study to ________.

A. decide who is more likely to enjoy a happier life

B. find out the link between personality and health

C. gather information for the National Institutes of Health

D. compare each woman’s personality changes

15. Who is more likely to die of cancer according to the text?

A. A woman who always doubts what others say.

B. A woman who doesn’t exercise

C. A woman with high blood pressure.

D. A woman with poor physical health.

16.What’s Hilary Tindle’s opinion of the study?

A. Unfair

B. Useless

C. Necessary

D. Reliable

D

Worlds of Fun

Location: Worlds of Fun is located off Highway 435 in Kansas City, Missouri.

History: Worlds of Fun was opened on May 26, 1973, at a cost of 25 million dollars. Loosely themed around the Jules Verne book, Around the World in Eighty Days, the park was founded by Hunt Midwest Company. In 1982, Hunt Midwest bought a nearby waterpark, Oceans of Fun. In 2013, Worlds of Fun and Oceans of Fun were combined to a one ticket admission, providing all guests with access to 235 acres of amusement and water rides.

Hours: Worlds of Fun is open from April through Halloween.

Tickets: Buy and print online. Always try to buy your tickets in advance, to save time when you get to the park.

Reservations: Worlds of Fun sells “Fast Lane” cards that save riders’ time by allowing them to bypass the majority of wait for most of rides and attractions including Mamba, Prowler, and Patriot. Ride as many times as you want all day long.

Strategy: Most visitors tend to begin the day with Prowler, the hottest attraction in the park. Use that tendency to your advantage and head to the Patriot first. After that, try the Dragons. Then work your way back to the Prowler. After riding the Prowler, there is only one coaster left, Mamba. Hit it next. If the park is not very crowded, you can ride Boomerang on the way to Mamba. After riding Mamba, head back for a ride on the Wolf. By then you will have tried most of the popular rides and attractions in the shortest possible time.

News: In 2017, Worlds of Fun is adding Steel Hawk, a ride that will take guests up 301 feet in the air and spin them at a 45-degree angle for a 60-second flight. Wait to have a try!

17. When di d Hunt Midwest’s two parks start to share one ticket?

Some things are 2 wrong,too.For instance, we should not hurt or bully(欺负) others, nor should we litter. Rules often tell us what is right or wrong..

广东省实验中学2018届高三上学期第一阶段测试

广东省实验中学2018届高三上学期第一阶段测试 广东省实验中学2018届高三上学期第一阶段测试 第卷（阅读题共70分） 一、现代文阅读（35分） （一）论述类文本阅读（9分） 阅读下面的文字，完成1-3题。 古代中国很早就建立了一支庞大的官僚队伍。 中国历史上一个鲜明的规律就是，历代官员的数量呈不断扩张趋势。明代刘体健称历代官数，汉七千八百员，唐万八千员，宋极冗至三万四千员。到了明代，文武官员共十二万余人。 官僚系统的不断扩张，是皇权专制制度不断强化的结果。官权是皇权的延伸，君主专制不断完善，注定官僚系统也不断延伸膨胀。秦汉以后，中央集权不断发生强化，官员的权力被不断分割，以期官员相互制衡，弱化他们对皇权的挑战。由此造成一官多职的现象，官僚队伍进一步扩大。 中国传统社会经济结构非常单一，传统赋税又主要只有农业税一途，官员数量的不断膨胀，使得俸禄成为财政支出的第一大项。比如西汉末年，国家赋税收入一岁为四十余万石，吏俸用其半，官员俸禄支出占国家财政收入的一半。所以支付官俸成为财政第一大难题，为了节省开支，薄俸制就成为大多数时候不得已的选择。特别是在皇权专制达于极致的明清两朝，官员薪俸之低也达到惊人的程度。 低俸制的另一个原因是皇权专制的自私短视本性。皇权专制本身是一项不合理的制度安排，它的设计原理是千方百计保证君主的利益，损害其他社会阶层的利益，这其中就包括官僚阶层的利益。在君主专制制度下，皇帝好比一个公司的老总，百官好比员工。压低员工工资，保证自己的利润，对老板来说是一种本能的偏好。从皇帝的视角看来，采取薄俸制和低饷制，用教育来要求百官清廉，既省心省力，又为国家节省了大量财政经费。 传统社会的低俸制，到底低到什么程度？以明代的县令收入为例。明代正七品县令月俸只有七石五斗。用七石五斗粮食养活一个大家庭甚至家族，这个县令的生活只能是普通市民水平。而且明代对于官员办公费用不予考虑，师爷、账房、跟随、门房和稿签等手下均需要县令来养活。再比如曾国藩在做翰林院检讨时，年收入为129两左右，年支出为608两左右。赤字480两左右，需要自己想办法弥补。这是当时京官的常态。 低薪薄俸为朝廷节省了大量的财政支出，也有利于培育出一批清官楷模。但与此同时，薄俸制也有着巨大的危害：它容易诱发腐败，并导致腐败的普遍化。权力笼罩一切，权力不受约束。与此同时，官员们却又只能拿到极低的甚至不能满足基本生活需要的薪水。这就形成了渴马守水，饿犬护肉的局面：让一条饥饿的狗去看着一块肥肉，那么无论你怎么打它，骂它，教育它，它也还是要偷吃，因为不偷吃它就活不下去。在低薪制下，选择做清官的毕竟只是少数，多数官员们不得不想办法搞一些灰色收入，这样贪污就无法根治。对最高统治者来说，这是占小便宜吃大亏之举，因为腐败最后给国家造成的经济损失比开足工资要大得多。 （摘编自张宏杰《顽疾：中国历史上的腐败与反腐败》） 1．下列关于原文内容的表述，不正确的一项是 A．古代中国官员的数量随朝代更迭不断增加，在中国历史上是一个不争的事实。 B．秦汉以后，皇权专制不断细化分割官员权力，目的在于减少官员对皇权的影响。
