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。

    I'm Jane. Today is Sunday (星期日). After lunch, my father plays games at home. My mother and I go to the store. My mother buys a green coat for my grandfather and a white shirt for my father. She buys some vegetables for dinner. And she buys some pears and bananas, too. I like reading (阅读), so I buy some books. I buy a toy ( 玩具) dog for my sister Lucy. She likes dogs very much.

    At 6:20 we get home and we have dinner at 7:00. In the evening we watch TV. I think I have a great Sunday.

    Thank you for watching Around China. I'm Li Ling, a reporter from CCTV. Now, we're in Penghu, Taiwan. The beach here is really beautiful and clean. Today is sunny, but the weather is hot and humid. There are lots of people. Some people are taking photos; some are swimming in the sea, and others are lying on the beach. Look at this group of young men playing beach soccer. They are only wearing sports shorts and sunglasses. They are running barefoot (赤脚的). They really look cool. I'm surprised that they can play so well in this heat. This is a very beautiful and interesting place. It's also a good place to relax. I like here so much that I really don' t want to leave.

    There are some skills for students to listen to the teachers in class, which means you're going to have to practice them. Just as you would have to practice basketball to be a better player, you also have to practice listening. How to listen in school? {#blank#}1{#/blank#}

    One of the things you'll need to do is to make sure that your mind doesn't wander(漫游). It's easy to start thinking about other things, especially when you are not interested in the subject. {#blank#}2{#/blank#}

   Next, listen for the main ideas. If you want to catch every little piece of information, you'll feel tired and bored. {#blank#}3{#/blank#} Not only does this show respect to the teacher, it also helps prevent your mind from wandering. {#blank#}4{#/blank#}Or it could just be someone talking to their neighbors who shouldn't be, it can even be some birds outside the classroom window, or a group of kids who are talking loudly as they pass the door to your room.

    Finally, you need to take notes because you will not remember everything the teacher said. You'll have to take down the notes so that you can study it after class. {#blank#}5{#/blank#}

    Listening isn't always easy, but if you follow these simple steps, you'll be much more successful in your classes.
