根据短文内容的理解,选择正确答案。

    When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool. Why? The sun makes the earth hot, but it can not make the water hot. Though the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up, then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean, you feel the cool air when it moves in. You feel the wind and the wind makes you cool.

    Of course, scientists cannot answer all of our questions. If we ask "Why is the ocean full of salt?" scientists will say that the salt comes from rocks. When a rock gets very hot or very cool, it cracks (崩裂), and rain falls into the cracks. The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask "What happens to the salt in the ocean? The ocean does not get saltier every year." scientists are not sure about the answer to the question.

    We know a lot about our world. But there are still many answers that we do not have, and we are curious(好奇的).

(1)、In the first paragraph, the underlined word "it" refers to        .
A、The hot air over the water B、The cool air over the earth C、The hot air over the earth D、The cool air over the water
(2)、Now scientists know           .
A、what makes people feel cool near a lake or an ocean in summer B、everything about the ocean C、what happens to the salt in the ocean D、why the ocean does not get more saltier
(3)、A rock crack when           .
A、rain falls B、it gets very hot C、it gets very cold D、Both B and C
(4)、Which of the following is NOT mentioned in this passage?
A、The reason why people feel cool when they are near a lake or an ocean in hot weather. B、The reason why the ocean doesn't get saltier every year. C、The reason why the water in the ocean is salty. D、The reason why rocks crack.
(5)、The main idea of this passage is that          .
A、people feel cool when they are near a lake or an ocean B、scientists can explain many things, but not everything C、scientists can explain everything about the ocean D、the salt in the ocean comes from rocks

    In the most southern part of our planet, there's a place that's covered with snow and ice all year round. But it has the clearest and cleanest air. Amazingly, in this place, the sun sometimes hangs even in the midnight sky. This place is Antarctica (南极洲): the coldest, windiest and harshest (恶劣的) place on the Earth.

    As the world's least-known place, Antarctica is of great interest to scientists around the world. During 30 years, China has sent many scientists to Antarctica. They mostly look at the resources under the icy land and do research about climate change and marine (海洋的) biology.

    Antarctica is a place with fantastic views. However, life there is very hard. Food is one of the biggest problems. Frozen food which can be heated easily is people's daily food. Fresh vegetables are hard to grow in the cold weather.

    Sleep is also difficult. In Antarctica, summer lasts from November to March. During this period, Antarctica points to the sun and receives sunlight 24 hours a day. In order to get some sleep, scientists cover the windows with black plastic cloth to create "night".

    Working in Antarctica is dangerous, especially when meeting gale-force (七级以上的) winds. They can easily blow people away. So there are ropes that connect buildings of some research stations. People can hold these ropes to keep their balance in forceful winds.

    What's morel communicating with others is difficult. Without cables and Internet in some research stations, two-way radios are the only tools to communicate. If people want to say hello to friends and relatives, they can use satellite phones.

    Although it is challenging to work in Antarctica, scientists' passion to learn about this mysterious land will never end. It is hopeful that one day they will step every corner of this icy land.

    Give your dead batteries a new life. Recycle them!

    Batteries(电池) are used to power clocks, computers, tools and more. However,

Your batteries have some serious power when their lives are over.

WHY TO RECYCLE BATTERIES

    Remember, batteries are harmful waste. This mean you could properly throw away. You may not think one little battery can cause that much pollution. But don't think of it as just one battery—there can be millions. In Canada, each person uses about 20 single-use batteries every year. That's about 700 million batteries! If all these batteries end up in landfills(垃圾填埋场), the heavy metals inside them can get into the water, land and air. It can be harmful to humans and wildlife.

    By recycling single-use batteries instead of throwing them away, you can cut down pollution and also help save energy. All batteries are mainly made of plastic and valuable metals. Through recycling programs, dead batteries can be changed into something useful like steel products, or even new batteries!

    HOW TO RECYCLE BATTERIES:

    Make a difference by starting to collect batteries at your home or school today. You can prepare a box for battery collection and invite friends, family and classmates to bring in old batteries to be recycled.

    There are many safe ways to deal with your batteries. You can:

    Find a Call 2 Recycle public collection station near you.

    Ask the store where you bought the batteries if you can return them there.

    Communicate with your local city government to find out if there are special programs for recycling used batteries!
