根据短文理解,选择正确答案。

    We know the mosquito very well. Mosquitoes fly everywhere. They are almost all over the world, and there are more than 2, 500 kinds of them.

No one likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It's true that the male mosquito doesn't bite and only the female mosquito bites because she needs blood to lay (产) eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn't like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember she chooses you. You're different from the others!

    If the mosquito likes you, she lands on your body without letting you know. She bites yon so quickly and quietly that you may not feel anything different. After she bites, you will have an itch (痒) on your body because she put something from her mouth together with your blood. By the time the itch begins, she has flown away.

And then what happens? Well, after the delicious dinner, the mosquito feels tired. She just wants to find a place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs.

根据短文理解,选择正确答案。

    Why do plants grow in some places but not in others? Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all?

    To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why there are almost no trees or grass in dry deserts.

    Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built (被建立) on hard land. The plants there have only the soil between the cracks of the stones to grow in.

    Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach? A few plants, such as grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

If something happens        , it happens quickly and unexpectedly (意料之外的).
