Questions 36 to 45 are based on the following passage.
For many Americans, 2013 ended with an unusually bitter cold spell. November and December（36） early snow and bone-chilling temperatures in much of the country, part of a year when, for the first time in two（37）, record-cold days will likely turn out to have outnumbered record-warm ones. But the U.S. was the exception; November was the warmest ever （38）, and current data indicates that 2013 is likely to have been the fourth hottest year on record.
Enjoy the snow now, because （39）are good that 2014 will be even hotter, perhaps the hottest year since records have been kept. That’s because, scientists are predicting, 2014 will be an EI Niuo year.
EI niuo, Spanish for “the child”, （40） when surface ocean waters in the southern Pacific become abnormally warm. So large is the Pacific, covering 30% of the planet’s surface, that the（41 ）energy generated by its warming is enough to touch off a series of weather changes around the world. EI Ninos are （42）with abnormally dry conditions in Southeast Asia and Australia. They can lead to extreme rain in parts of North and South America, even as southern Africa（43） dry weather. Marine life may be affected too; EI Ninos can （44 ） the rising of the cold, nutrient-rich（营养丰富的）water that supports large fish （45）,and the unusually warm ocean temperatures can destroy coral(珊瑚).
Much of the energy that comes from the sun never reaches the earth's surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the earth's surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the earth's surface back to the earth. These gases act like the glass of a greenhouse in that they allow energy from the sun to enter but prevent energy form. leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. Dark-colored surfaces, such as dark soil or forest, absorb more energy.
According to the passage, the root cause for weather changes on the earth is
A．the atmosphere surrounding the earth
B．water from oceans and lakes
C．energy from the sun
D．greenhouse gases in the sky
W: Oh, please be serious! I suppose they will change shapes as well. If you want a big car to take all your friends camping, I suppose you'll just be able to snap your fingers and make it happen. Or if you want a sporty two-seater, you could just tell the car what you wanted, and it would do the rest. Is that how it will work？
M: No, I am serious. They have found a way to alter the surface of metals so that they can reflect different colors just by passing a small amount of electricity over them.
W: Oh, I see. So anything that touches the outside of the car will get a shock. That sounds lovely.
M: It's only a tiny amount of electricity. It wouldn't be enough to shock anybody.
W: Well, it sounds pretty difficult to believe.
M: Yes, it's quite amazing. The important thing you have to remember is that the color of an object is really just an illusion created by the way light bounces off its surface. Engineers have been able to produce a car that changes colors at the touch of a button by slightly rearranging the position of the particles on the surface of the metal.
W: It sounds so amazing. But I guess it could be possible.
M: It is possible today. The only problem is that it is very expensive. To produce a car with a surface that changed colors would cost almost twice as much as what a regular car costs. For that much money you could just by the car and have it repainted twenty times, so it's not very practical yet.
W: Yes, but in other ways it could be more practical. If you took your car to be painted twenty times, it would use quite a bit of polluting chemicals, and it would take a long time.
M: You're right there, but how many people really get their car repainted that many time？
W: Hmm, I suppose you're right, but I sure would love to have my car match my outfit every day.

A．She is impressed.

C．She is shocked.
D．She is surprised.
Journey to Australia
Australia is one of the famous Oceanian countries. The country is famous for its（）production and seashore tour. As the climate there is warm and comfortable, many people spend vocations there every year.
I’m a super fan of water（）, so I choose it as my destination.
In Australia, the sky is bluer than blue, the clouds are whiter than white, all the local people enjoy an（）and active life. They also show their kindness and enthusiasm to the tourists.
The first step should be（）Opera which is among the most brilliant and splendid architectures in the world. Many world-class（）are put on in it .The surface and shape of it is like a seashell with glory decorations inside. Then Melbourne is a good choice to be as the next step. In Melbourne, skin screen（粉底） is a must to take with as the sunshine is upset and may burn your skin. The most attractive thing to me is the Australia Open（澳网公开赛），which is one of the biggest world-class tennis competition. Many great players such as Roddick Federer and its local player Hewitt etc. gather to compete. It S really a feast for the eyes.

Air is a gas that expands (膨胀) when heated, gets lighter, and moves upward. When air is
cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warm air rises, cold air rashes to take its place. Thus winds originate (起源). Tile winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.
The first paragraph mainly tells us______.
A．why we don't feel air
B．why atmosphere is important to us
C．why there is air surrounding us
D．why there is air pressure
