【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项根据短文内容.

Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely(绝对地) terrifying.

【1】 . However, most deaths result from fear, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

Brace yourself for impact (撞击力). As soon as you're aware that you're going off th e road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel(方向盘) in the "ten and two" position.

Undo your seatbelt. 【2】 . Release the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.

【3】 . Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape choice either because of fear or misinformation about doors and sinking.

Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. 【4】 .

Escape when the car has equalized. If it has reached the stage where the car has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. 【5】 . While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. This is the first thing to do, yet it often gets forgotten.

C. Surviving a sinking car is not as difficult as you think.

D. In short, if you know what to do in the water, you will be safe.

E. It takes 60 to 120 seconds for a car to be filled with water usually.

F. Such accidents are particularly dangerous to the risk of drowning(淹死).

G. But the sooner the window is open, the sooner you can escape directly through it.

【题目】The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid--we simply weigh too much, and all our mass 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, 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 take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting. “

But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water group 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 an 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 handy in case you start to sink--and take a shower afterward!

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

A. are not interested in it

B. have biological limitations

C. have not invented proper tools

D. are afraid to make an attempt

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

A. It is light enough to walk on water.

B. Its huge feet enable it to stay above water.

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

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 create a thick liquid.

B. To turn the water into solid.

C. To help the liquid behave normally.

D. To enable the water to 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 interesting and worth trying.

C. It is crazy and cannot become a reality.

D. It is impractical though theoretically possible.

【题目】The Farmer, His wife, and the Open Door

Once upon a time, there lived a poor farmer and his wife. One day, having finished their day’s labor and eaten their simple supper, they were sitting by the fire. 【1】 It was blown open by wind.

“Darling, shut the door!” said the man.

“No way, shut it yourself!” said the woman.

“I will not shut it, and you shall not shut it,” said the man, “but let the one who speaks the first word shut it.”

In the middle of the night they heard a noise, and looking around, they found that a wild dog had entered the room, and that he was busy eating their food. Not a word, however, would either of these silly people say, and the dog, having eaten as much as he wanted, went out of the house.

【3】

When she was out, a barber entered, and said to the husband, “Why are you sitting here all alone?” 【4】 The barber then shaved his head, but still he did not speak; then he shaved off half his beard, but even then the man kept silent. “The man is crazy!” cried the barber, and he quickly escaped out of the house.

At the moment, the wife returned from the shop. 【5】 .
