    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。

    Bob and I live in the same building. His room is on the tenth floor, and mine, the ninth. He is kind but careless.

    One day Bob and his friends went to an island for traveling. On the island, they swam, fished and had a picnic. They enjoyed themselves very much. Three days later, they decided to come back by boat. On the way, their boat hit a rock and soon went down. They were all in danger. Luckily, all of them were out of danger with a villager's help. At that time, Bob was quite hungry and tired, so he hoped to get home as soon as possible.

    When he got to the building, it was already midnight. As the lift(电梯）didn't work, Bob had to go upstairs on foot. He stopped by my door and took out his key to open it. Of course, he could not open the door. He tried it again and again, but failed. He became angry and shouted. " What's wrong , my god?" The noise woke me up. I opened the door. I understood at once what was happening and said," You are wrong. It's my room, Bob!"

    "Oh, no, Mike!" Bob shouted, "It's my room. You have opened the door by mistake!"

    Andy was still traveling in Spain when he realized he had to confirm (确认) his     home with the airline company. He was visiting Spain in order to improve his Spanish. When he was speaking to people face to face, he had no difficulty understanding what they said. However, when he was speaking on the phone, he still had a problem. Andy called the airline. And the clerk confirmed that his plane was leaving at nine o'clock three days from that day. She also told Andy to be at the airport a little earlier in order to check in his luggage and get a seat.

    Since he was leaving in three days, Andy didn't lose any time. He visited as many places as he could. He thought that it would probably be a while before he had enough money again. He wished he could come back and spend a year in Spain.

    Too quickly, the final day arrived. Andy left early for the airport before take-off. He hated to rush. When he went to the clerk to show his ticket, the clerk looked at the ticket in surprise, "Why, sir, but your flight was at nine o'clock in the morning, and now it is eight in the evening." "But I confirmed my flight," insisted Andy. "Will I have to pay for another ticket?"

    "No, Sir. However, the next flight out will be three days from now."

    Andy's      of shock turned to smile as he realized that now he could go on with his vacation.
