【题目】Humans have long been interested greatly in the idea of being able to walk on water. Sadly, biological facts prevent us ever realizing this dream without artificial aidwe simply weigh too much, and all our weight pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will reach a speed of 20 steps per second to keep moving forward. For humans, we would need huge feet that we could bring up to our ears in order to create enough “hitting”.

But fortunately there is an alternative: cornflour(玉米淀粉). By adding enough of this common thickening agent to water (and it does take a lot), you can create a special mixture that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water get together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of this adequately thick liquid of cornflour.

Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings(救生圈) ready in case you start to sinkand take a bath afterward!

【1】Walking on water hasn't become a reality mainly because humans _________.

A. are not interested in it

B. are afraid to make an attempt

C. have not invented proper tools

D. have biological limitations

【2】What do we know about Basilicus basilicus from the passage?

A. It is light enough to walk on water.

B. It can run across water at a certain speed.

C. Its huge feet make it able to stay above water.

D. Its unique skin keeps it from getting wet in water.

【3】What is the function of the cornflour according to the passage?

A. To help the liquid behave normally.

B. To turn the water into solid.

C. To create a thick liquid.

D. To make the water move rapidly.

【4】What is the author’s attitude toward the idea of humans’ walking on water?

A. It is risky but beneficial.

B. It is impractical though possible in thoery.

C. It is crazy and cannot become a reality.

D. It is interesting and worth trying.

【题目】In Los Angeles, drivers spend sixty-one hours every year stuck in traffic. These drivers know all too well how bad the traffic can be. “There’re too many cars, and you can’t move around a lot.”

Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation (导航) system.He decided to develop a program called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house. “What’s unique (独特的) isthat we use a lot of data that’s currently become available including traffic data, weather data, and we analyze that so that we can predict what’s going to happen in front of you when leave home.”Professor Shahabi says his system does more than just answer current traffic conditions. With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give thefastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road. Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.

“I always thought that Los Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this.”Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.

【1】Professor Cyrus Shahabi is often late for work because of ________.

A. his living far away

B. his car’s navigation system

C. bad traffic conditions

D. too many cars in his university

【2】What is unique about ClearPath?

A. It helps drivers know the road conditions ahead of time.

B. It can make sure that you will never be late for work.

C. It helps drivers see clearly what happens on the road.

D. It can use a lot of information and data all over the world.

【3】The underlined word hits” in the fourth paragraph probably means ________.

A. has accident

B. gets to

C. turns left or right

D. collects traffic data

【4】What’s Professor Shahabi’s attitude toward his invention?

A. Proud. B. Worried.

C. Disappointed. D. Optimistic.

【题目】A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.

An electromagnetic field(电磁场) will pull particles(微粒) in the smog to the ground where they can be easily cleaned.

“It's like when you have a balloon which has static(静电) and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.

His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.

With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.

Roosegaarde says an indoor model device has already proven it works and is confident that the results with the help of a team of scientists and engineers can be replicated outside.

“Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”

“We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”

Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution.

“This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”

However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.

【1】The device works by _______.

A. helping keep the particles out with more masks

B. pulling pollutants to the ground with an electromagnetic field

C. absorbing hair with a balloon with static

D. creating clean air and let it out into the sky

【2】According to the passage, ______ .

A. the Beijing government has agreed to use the technology in Beijing

B. they have proven the results of the device both indoors and outdoors

C. the results of the air-cleaning device can be expectable

D. the Beijing government has never done anything to handle the air pollution

【3】What does Roosegaarde really mean by saying “Beijing is quite a good place…... ”?

A. The air pollution in Beijing is not quite serious.

B. The weather in Beijing is good for foreigners to live in.

C. Beijing is quite fit for using the air-cleaning device.

D. It is easy to get the top of the smog in Beijing.

【4】Roosegaarde appeals to people in Beijing to ________.

A. pay attention to air pollution and solve the problem finally

B. invent more devices to clean the smog in Beijing

C. drive modern cars and try different lifestyles

D. realize how serious the pollution they're facing is

【题目】Whoever has made a voyage up the Hudson River must remember the Catskill Mountains. They are a branch of the great Appalachian family, and can be seen to the west rising up to a noble height and towering over the surrounding country. When the weather is fair and settled, they are clothed in blue and purple, and print their beautiful shapes on the clear evening sky, but sometimes when it is cloudless, gray steam gathers around the top of the mountains which, in the last rays of the setting sun, will shine and light up like a crown of glory(华丽的皇冠).

At the foot of these mountains, a traveler may see light smoke going up from a village. In that village, and in one of the houses (which, to tell the exact truth, was sadly time-worn and weather-beaten), there lived many years ago, a simple, good-natured fellow by the name of Rip Van Winkle.

Rip’s great weakness was a natural dislike of all kinds of money-making labor. It could not be from lack of diligence, for he could sit all day on a wet rock and fish without saying a word, even though he was not encouraged by a single bite. He would carry a gun on his shoulder for hours, walking through woods and fields to shoot a few birds or squirrels. He would never refuse to help a neighbor, even in the roughest work. The women of the village, too, used to employ him to do such little jobs as their less helpful husbands would not do for them. In a word, Rip was ready to attend to everybody’s business but his own.

If left to himself, he would have whistled life away in perfect satisfaction; but his wife was always mad at him for his idleness(懒散). Morning, noon, and night, her tongue was endlessly going, so that he was forced to escape to the outside of the house the only side which, in truth, belongs to a henpecked husband.

【1】Which of the following best describes the Catskill Mountains? ________

A. They are very high and beautiful in this area.

B. They are on the west of the Hudson River.

C. They can be seen from the Appalachian family.

D. They gather beautiful clouds in blue and purple.

【2】The hero of the story is probably__________.

A. hard-working and likes all kinds of work

B. gentle, helpful but a little idle

C. simple, idle but very dutiful

D. idle and hates all kinds of jobs

【3】The underlined words “henpecked husband” in the last paragraph probably means a man who__________.

A. likes hunting B. is afraid of hens

C. is afraid of his wife D. loves his wife

【4】 What would be the best title for the text? ________.

A. Catskill Mountains. B. A Mountain Village.

C. A Dutiful Husband. D. Rip Van Winkle.
