試題分析：考查倍數(shù)表達(dá)法。倍數(shù)表達(dá)有四種：1. “A+倍數(shù)+形容詞或副詞的比較級+than+B”， 2.“A+倍數(shù)+as+形容詞或副詞的原級+as+B”， 3. “A+倍數(shù)+the size/height/length/width， etc+of+B”， 4. “……times+what+從句”。在這4種表達(dá)法中，倍數(shù)都要放在最前面。本題使用了第2種。句意：為下屆亞運(yùn)會所建的新的體育館是現(xiàn)在這座體育館的三倍大。根據(jù)句意說明A正確。
點(diǎn)評：倍數(shù)表達(dá)要牢記，倍數(shù)表達(dá)法是高中英語教學(xué)的重點(diǎn)，也是歷屆高考的熱點(diǎn)。當(dāng)我們要表達(dá)甲是乙的幾倍時，通常用句型來表示：
1. “A+倍數(shù)+形容詞或副詞比較級+than+B”，表示“A比B大（長、高、寬等）多少倍”
This rope is twice longer than that one. 這根繩子是那根繩子的兩倍長（比那根繩子長一倍）。
2.“A+倍數(shù)+as+形容詞或副詞的原級+as+B”，表示“A正好是B的多少倍”。如：
Asia is four times as large as Europe. 亞洲的面積是歐洲的四倍。
3. “A+倍數(shù)+the size/height/length/width， etc+of+B”，表示“A正好是B的多少倍”。如：
This street is four times the length of that one. 這條街是那條街的四倍長。
4. “……times+what+從句”。如：
The production is now three times what it was ten years ago. 現(xiàn)在的產(chǎn)量比十年前增加了兩倍。

What is your favourite colour? Do you like yellow, orange, red?  小題1:  . Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist(悲觀者). At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings.  小題2:  .If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
 小題3:  . A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day.  小題4:  .A black bridge over the Thames River, near London, used to be the scene of more suicides(自殺) than any other bridge in the area---until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
 小題5:  .It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.
A．On the other hand, black is depressing（使人憂傷）.
B．They tell us, among other facts, that we do not choose our favourite colour as grow up --- we are born with our preference.
C．The rooms are painted in different colours as you like.
D．If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.
E. Light and bright colours make people not only happier but more active.
F. Life is like a picture or a poem, full of different colours.
G. Colours do influence our moods---there is no doubt about it

Students go to colleges and universities to have valuable experiences and learn to live in their own. Go to colleges often means having the opportunity to meet with different peoples from different parts of the country. They learn to communicating and co-operate with each other. For most students, we guess, it is the first time that they had been away home. They are faced by many new situations and have to learn to solve them independently, making decisions on our own and dealing with various things themselves. So colleges and universities help with them grow up.

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項，選項中有兩項為多余選項。 （請把本題答案涂在答題卡上，若所用的答題卡沒有E、F、G選項，則選E涂為AB，選F涂為AC，選G涂為AD。）
Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.   1  However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace (支撐) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.
Brace yourself for impact (撞擊力). As soon as you're aware that you're going off the 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 in the "ten and two" position.
Undo your seatbelt.   2  Untie 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 option either because of panic 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 dramatic stage where the car cabin 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. Surviving a sinking car is not as difficult as you think.
C. It takes 60 to 120 seconds for a car to fill up with water usually.
D. Such accidents are particularly dangerous to the risk of drowning.
E. In conclusion, if you know what to do in the water, you will be safe.
F. This is the first thing to attend to, yet it often gets forgotten in the panic.
G. But the sooner the window is open, the sooner you can escape directly through it.
