    Look! People are gathering to get water from a huge well in the village of Natwarghad in the western Indian state of Gujarat! ①Because of the large population on the earth, the world is ________hungry, it is ______be thirsty for water now. The world's population has reached 7 billion. And it could possible grow to 15 billion by the year 2100.

    ②On the other hand, about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink or use the other 3% of fresh water which comes from rivers, lakes and underground. And we can't even use all of that, because some of them has been polluted.

    Now more water is needed. The problem is: can we avoid a serious water shortage later on? Firstly, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Today, in most large cities water is used only once, but it can be used again .Even if every large city reuse its water, still there would not be enough. What could people turn to next?

    The sea seems to have the best answer. The sea is very big. Look at the map of the world, there is more sea than land. It covers three quarters of the earth. All that needs to be done is to get the salt out of the sea water. Scientists are trying to find a cheaper way of doing it. So you see,③如果我们可以找出解决方法，我们就不会有干涸（dry up）的危险。

    Do you know anything about the way of shopping in Western countries? In the West, people usually make a list before they go shopping. Most people like to go to supermarkets or big shopping malls.

    In the West, most supermarkets or malls open at 8:00 a.m. and close at 6:00 p.m. But some big supermarkets and big malls are open until 11:00 p.m. at night. When people go into a supermarket, first they should get a basket or a cart(手推车) at the entrance(入口处). Then they begin to choose things and put them into the basket or the cart. After they get everything they want, they pay the money. There are always a lot of people in the supermarket at weekends. They must wait for their turn.

    Most people go to the supermarket or the shopping mall once a week. Some people go shopping twice or three times a week.

    Most of us probably dreamed about becoming an astronaut when we were little. But how many of us have actually become one, or are at least working toward it? It's true that the advice" Always follow your dreams" is something that is typically easier said than done.

    But still, this is the one piece of advice that Alyssa Carson wants to share with her peers. This 17-year-old girl from the US has become one of the candidates (候选人) for NASA's 2033 project to go to Mars. If everything goes well, Carson will be one of the first human beings to ever set foot on the red planet.

    Carson began to dream of going to Mars when she was only three years old. After watching an astronaut-themed cartoon and hearing from her father that humans had only been to the moon but not Mars, Carson decided that she wanted to be the first one to do so.

    To realize her dream, she has worked hard toward it. At the age of 12, Carson became the first person to attend all three NASA space camps, and she sat with real astronauts to discuss the future of Mars missions. Now 17, Carson is continuing with her space training while still taking on her high school work like a "normal " teenager, except that she studies all her subjects in four languages - English, French, Spanish and Chinese.

    "I don't think there's anything specific that makes it easier for me or makes it something that others can't do," Carson said in an interview," I've just really focused myself on what I want to accomplish."

    Besides, Carson is willing to make sacrifices (牺性) for her dream, She's fully aware of the danger of the mission and the possibility that she might never be able to come back. She also accepts the fact that she can't get married and start a family because any loved ones left on Earth may be a distraction for her and for the mission, But Carson believes that it's all worth it, summarizing her view with this ancient Greek proverb she once quoted," A society grows great when old men plant trees whose shade they know they'll never sit in."

    While some people's dreams may sound out of this world, Carson is on her way.
