B

    In the movie 2012 , people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and con?structions representing human civilization being destroyed and even swallowed by disasters. Luckily, they are just the directorV imagination,but the present situation is not heading for a positive direction, either.

    Take my own experience in Alaska as an example. Once I took a trip to the glacier(冰川).Along the way there stood signposts marking the snowline of different years. They started from the foot of the mountain, but it was at the top when I fi?nally saw melting glaciers. My heart ached seeing the beautiful blue ice melting at every second.

    Sad but true, they are the effects of global warming and the result of our hu?man impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the entire Italy. According to studies* if the tem?perature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.

    Our fortune is in our own hands. It depends on us to shape our future, to re?duce future human impact and to find ways to form a peaceful relationship with our environment. Therefore, it's time for action to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let re?cycling become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it's to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoiding destroying them.

In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home.  It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming a reality,

A [2015 •河北省容城中学高一英语下学期期中测试]

The earth is the only planet that scientists think has life. Why does the earth have life while other planets don't? For one thing, the earth has just the right temperature. As the third planet from the sun j the earth seems to be just the right distance away. The planets which are closer to the sun are so hot that their surfaces bake in the sun. The far?thest planets are cold balls.

   When the earth developed―which scientists believe may have happened about 4 billion years ago many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.

Only one other planet in the solar system seems to be something like the earth. That planet is Mars(火星).Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit, you could walk around on Mars. You would have to bring your own air to breathe, because the air on Mars is too thin to breathe.

Mars has the largest volcano (ill) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected(未fiS测到的)sight on Mars is dried-up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.

1.    Which of the following is NOT the reason that the earth has life?

  A.  The earth has just the right temperature.

B.  The volcanos on the earth are lower than those on Mars.

C.  There is oxygen in the atmosphere of the earth.

D.  The earth seems to be just the right distance away from the sun.

2. The underlined phrase "the third planet" in the first paragraph refers to    .

A.   the sun      B.   the moon     C.   the earth    D. Mars

3.    Which of the following about Mars is NOT true?

  A.  There could have been living things on Mars.

B.  Mars has the largest volcano in the solar system.

C.  There is almost no oxygen in the air on Mars.

D.  Mars is smaller than the earth, and it is quite a bit cooler.
