第三部分阅读理解(共20小题;每小题2分,满分40分)

A

The Atacama Desert is located just west of the Andes, a 1000-km strip(狭长的地域) of land next to the Pacific Ocean. In spite of its location beside the sea, several studies have shown that this region is the driest place in the world. In the Antofagasta Region of the desert, the average annual rainfall is just 1 mm and some weather stations have never received rain at all. Atacama is so arid that the surrounding mountains that reach up to 6885 m, have absolutely no glaciers! In the region, the river beds have been dry for over 120,000 years.

However, unlike the Sahara Desert,Atacama is surprisingly not that hot. It has an average daily temperature between 0'C and 25℃! If you find that surprising, you'd be shocked to find out that this desert has lakes!

When there was rainfall in the region (many year ago), this accumulated water created what we now know as the Salt Lakes. The name of these lakes was given as a result of the effect of the Atacama environment: the long dry period makes the water evaporate(蒸发),resulting in the higher concentrations of salt in the remaining water.

This region has been tested by scientists to see if life is present in the Atacama soil with the same instruments that would be used to detect life in the soil on Mars! As a result of the soil's similarites to that of Mars,the Atacama land is used to test instruments for future Mars missions. In addition, the region has been used in movies as a set for filming Mars scenes, most famously in the television show Space Odyssey: Voyage to the Planets.

The Atacama Desert is truly a unique place, due to its lack of rain as well as its similarities to Mars. You would think that this place would be a bare ghost town (鬼域), but think again! Many people have lived here for centuries, giving this desert its own culture and economic significance.

56. What does the underlined word "arid" in the first paragraph mean?

A. Big.

B. Dry.

C.Hot.

D. Long.

https://www.360docs.net/doc/a513060930.html,pared to the Sahara Desert,the Atacama Desert is _____.

A.smaller

B. wetter

C. less famous

D. less hot

58.What is Paragraph 3 mainly about?

A.origin of the Salt Lakes.

B.rainfall in the Atacama Desert.

C.the weather in the Atacama Desert.

D.The current situation of the Salt Lakes.

59.The TV program mentioned in the text____.

A.tells Atacama's similarities to Mars

B.focuses on the soil of Mars

C.explores life in Atacama

D.was filmed in Atacama

60.According to the author, the Atacama Desert ___.

A.is a very frightening place

B.is as mysterious as Mars

C.is somehow livable

B

While nature lovers across the world wish all humans to realize the significance of their natural surroundings, many Australians are turning caring for the environment into a way of life.

Julie Astonis, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming (盛开的) flowers in Julie's little garden, as she tells that in her community, "Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden."

"Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures,but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year."

Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile.“T aking care of the the dog’s waste can also help to develop children's sense of responsibility!”

As to protecting water resources, the Australian goverment has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater,which is later used as the resource of all outdoor water use,including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.

61.From the fIrst three paragraphs we learn that_____

63.What do we know about Julie from Paragraph 4?

A.She takes pride in her community.

B.She once stepped on a dog's waste.

D.She is quite in favor of raising a dog.

D.She finds it embarrassing to walk on the grass..

64.From what Julie says in the last paragraph, we know___.

Xiangzi –Lucky, in English - is appropriately named. His owner Qiu Hong, a sports marketer,lets the dog enjoy two daily walks,a collection of imported American toys, $300 worth of monthly food and treats and his own sofa in her high-rise apartment. When Ms. Qiu feels bored, she takes Xiangzi out for a long run in her car.

In a sense, Xiangzi is not just a dog, but a social phenomenon – and, perhaps, a marker of how quickly the Chinese nation is booming through its transformation from poor farmer to first-world citizen.Twenty years ago,there were hardly any dogs in Beijing, but now there're 900,000 registered dogs with countless thousands of others unlicensed. How this came to be is, in some ways, the story of modern China as well.

"People used to be focused on improving their own lives, and they weren't really acquainted with raising dogs," said Ms. Qiu. "But with the improvement in the economy,people's outlooks (观念) have changed."

Having a dog can be a way to relieve the stress in people's lives, but mostly Beijing dogs have, as in the West, become objects of affection - even devotion - by their owners. It's easy to find dog-treat stores, dog Web sites, dog social networks, dog swimming pools – even, for a time recently, a bring-your-dog cinema and a bring-your-dog bar on Beijing's downtown nightclub row.

The doglike devotion of pet owners here seems to have softened the city government heart. In 1994,Beijing officials relaxed their no-dog policy to "severely restrict" dogs. In 2003,it was changed again to allow anyone to own a dog,but to limit city dogs to no more than 35 centimeters in height. And nowadays the restriction seems to be loosely carried out.

As for sti-fried Pekingese (京叭狗) - well,that dog,too, may have seen its day. A formal suggestion to ban the eating of dogs has been made by a law professor named Chang Jiwen,who considered himself "not so much a dog lover as a China lover". "With China developing so quickly, more people should know how to treat animals properly," he said in 3 telephone interview.

66. What's the main idea of the first paragraph?

A.Xiang Zi is a clever dog.

B. Xiangzi lives a happy life.

C. Qiu Hong has a lot of money.

D. Qiu Hong is very busy.

67. Paragraph Four mainly shows that Beijingers_____.

A.Iive under too much pressure

B.Iove dogs evry much

C.are good at making money

D.have modernized their city

68.Judging from the article,we can know that______.

A.Pet owners can be as devoted as the dog

B.there were no dogs in Beijing before 2003

C.Beijing strictly bans dogs above 35cm high in practice

D.Chang Jiwen spoke for dog lovers only

69.Which is NOT mentioned in the article?

A.China’s economical development.

B.The psychological problems in modern society.

C.People’s attitude to wards animals.

D.The problems caused by dog keeping.

70.Which can be the best title of the article?

A.Chinese Dogs Are Lucky

B.Dogs Help Humans Live Better

C.Dogs Reflect China’s Rise

D.Dogs Enjoy More Freedom In Beijing

D

[1] Nowadays, researchers from the University of Maryland found that nearly four in five students have depression,panic,confusion and extreme isolation when they are forced to keep away from technology for a day.The study concluded that "most students failed to go the full 24 hours without media". They have been addicted to the modem technology.

[2] In this research, almost 1,000 university students from 12 campuses in 10 countries, including Britain, America and China, have been interviewed. Most of them were unable to avoid technology for one full day. The researchers concluded that, college students at campuses

across the globe admitted being "addicted" to modem technology such as mobile phones, laptops and televisions as well as social networking such as Facebook and Twitter. An American college student told of his great desire when he was forced to keep away from the media. He even said it "cocaine addiction".

[3]The research also found students used "nearly the same words to describe their reactions when they were away from the media”.These included emotions such as confusion,anxiety, insecurity, jealousness, anger, loneliness, dependence and depression.

[4] Professor Susan Moeller, who led the research, said technology had changed the students' relationships. "Students talked about how seary(可怕的) it was when there is no technology, how addicted they were to it," she said. "They expected the frustration without the media. But they didn't expect to have the psychological effects,to be lonely, to be panicked, the anxiety, literally heart palpitations (心悸). Technology provides the social network for young people today and they have spent their entire lives being ‘plugged in ' . "

Writing (One possible version):

Nothing Succeeds Without a Strong Will

It is universally acknowledged that people cannot succeed or achieve their targets without a strong will and persistence. One of the most typical examples is that in the present-day society, a growing number of people give up or fail to quit smoking just because of their poor willpower during the process. A variety of factors may account for this phenomenon as follows.

For one thing, no one can deny the fact that persistence is the key point in accomplishing one’s task. It is of importance for people to s tick to their original aim. A great number of dragsters would stop smoking a couple of days after they have made their determination, but only a few of them may succeed in the end. For another, the people who cannot quit smoking may easily be affected by his circumstance and surroundings. In that case, people tend to fail to resist various temptations around them.

From what has been discussed above, we may safely come to the conclusion that only by concentrating on the object and strong self-discipline can we obtain our goals successfully in the future.

试题4: 为了证实玻尔关于原子存在分立能态的假设,历史上曾经有过著名的夫兰克—赫兹实验,其实验装置的原理示意图如图所示.由电子枪A射出的电子,射进一个容器B中,其中有氦气.电子在O点与氦原子发生碰撞后,进入速度选择器C,然后进入检测装置D.速度选择器C由两个同心的圆弧形电极P1和P2组成,当两极间加以电压U时,只允许具有确定能量的电子通过,并进入检测装置D.由检测装置测出电子产生的电流I,改变电压U,同时测出I的数值,即可确定碰撞后进入速度选择器的电子的能量分布. 我们合理简化问题,设电子与原子碰撞前原子是静止的,原子质量比电子质量大很多,碰撞后,原子虽然稍微被碰动,但忽略这一能量损失,设原子未动(即忽略电子与原子碰撞过程中,原子得到的机械能).实验表明,在一定条件下,有些电子与原子碰撞后没有动能损失,电子只改变运动方向.有些电子与原子碰撞时要损失动能,所损失的动能被原子吸收,使原子自身体系能量增大, (1)设速度选择器两极间的电压为U(V)时,允许通过的电子的动能为E k(eV),导出E k(eV)与U(V)的函数关系(设通过选择器的电子的轨道半径r=20.0 cm,电极P1和P2之间隔d=1.00 cm,两极间场强大小处处相同),要说明为什么有些电子不能进入到接收器. (2)当电子枪射出的电子动能E k=50.0 eV时,改变电压U(V),测出电流I(A),得出下图所示的I—U图线,图线表明,当电压U为5.00 V、2.88 V、2.72 V、2.64 V时,电流出现峰值,定性分析论述I—U图线的物理意义. (3)根据上述实验结果求出氦原子三个激发态的能级E n(eV),设其基态E1=0. 试题5: 曾经流行过一种向自行车车头灯供电的小型交流发电机,图1为其结构示意图。图中N、S是一对固定的磁极,abcd为固定在转轴上的矩形线框,转轴过bc边中点、与ab边平行,它的一端有一半径r0=1.0cm的摩擦小轮,小轮与自行车车轮的边缘相接触,如图2所示。当车轮转动时,因摩擦而带动小轮转动,从而使线框在磁极间转动。设线框由N=800匝导线圈组成,每匝线圈的面积S=20cm2,磁极间的磁场可视作匀强磁场,磁感强度B=0.010T,自行车车轮的半径R1=35cm,小齿轮的半径R2=4.cm,大齿轮的半径R3=10.0cm(见图 2)。现从静止开始使大齿轮加速转动,问大齿轮的角速度为多大才能使发电机输出电压的有效值U=3.2V?(假定摩擦小轮与自行车轮之间无相对滑动)
