Luis and his wife Gloria live in a nice apartment, but it isn't big enough. They need a house with at least three bedrooms. They also want to have a yard for the children to play in. And so far they  {#blank#}1{#/blank#}  (look) at several houses that are for sale. One of them was beautiful but terribly expensive. Their business isn't going well. so they can't afford an expensive house. That's why they  {#blank#}2{#/blank#} (search) for one that doesn't cost a lot, and, of course, that's not easy to find.

 Yesterday they looked at four houses, and three of them {#blank#}3{#/blank#}  (be) great. But they couldn't afford the houses they liked, and they didn't like the one they could afford. The only affordable one was old and had cracks（裂缝）in the walls. Last night, Luis and Gloria talked about the house for two hours. “I know we{#blank#}4{#/blank#}  (not find) anything that costs less, and I want to move as soon as I can,” said Luis. “And I'm tired of looking at houses we can't afford,” Gloria added. So they decided to buy the old house and repair it. The house will need a lot of work, but it's a nice neighborhood and the back yard is big. It'll look beautiful when it  {#blank#}5{#/blank#}   (repair). Luis and Gloria are good at painting, and some of their friends will help with the repairs. The children will be happy  {#blank#}6{#/blank#}    (have) their own house where they can make all the noise they want.

    There was a small village near a mountain. People there loved their village very much and they grew many {#blank#}1{#/blank#} on the mountain. Water in the rivers was very clear and the {#blank#}2{#/blank#} was clean. People lived a poor life, but they were very {#blank#}3{#/blank#} . After a few years, some people in the village started to cut down trees to {#blank#}4{#/blank#} for money. There were some people from cities {#blank#}5{#/blank#} to visit the village. People began to kill some wild animals as {#blank#}6{#/blank#} to treat (招待) the visitors. Of course, they made lots of money. But {#blank#}7{#/blank#} knew what the village would be like in the future. As time went on, there were fewer plants and animals and the water became {#blank#}8{#/blank#}. The visitors became fewer and fewer. Several years later, people there knew they must stop destroying (破坏) {#blank#}9{#/blank#} . They would like to live a happy life as before, so they began to {#blank#}10{#/blank#} new plants. They hoped the village would become as beautiful as before.

Dear Brad,

    In about 3 months, I will take a very important test. If I {#blank#}1{#/blank#} (pass) the test with good grades, I can get to the 10^th grade and choose a good school {#blank#}2{#/blank#} (study) in. Now I am trying my best to make my dream {#blank#}3{#/blank#} (come) true. At the same time, I'm the monitor in my class, which means I should do lots of things for my class. I am so busy with my school work and duties as a monitor that I don't have enough time {#blank#}4{#/blank#} (keep) a balance between them. Gradually I become lazy. The other day, my head teacher {#blank#}5{#/blank#} (tell) me that she was disappointed in my poor performance as the class monitor. Her words really discouraged me.

    What should I do now, to give up or not to give up as the class monitor? I must {#blank#}6{#/blank#}(do) my best in school because how well I do will influence where I go after this school year is over and it can affect the rest of my life. {#blank#}7{#/blank#} (be) a class monitor is also a valuable learning experience because my teacher trusts me {#blank#}8{#/blank#} (be) a good leader. I don't want {#blank#}9{#/blank#} (go) to my parents for suggestions, for they will get worried about me. Can you tell me how {#blank#}10{#/blank#} (choose)?

                                                                                                                                                                                  Yours,

                                                                                                                                                                                   Gates

    The population of the Earth is growing faster. It is important that we should care for the{#blank#}1{#/blank#}. We need it.

    The Earth gives {#blank#}2{#/blank#} a lot of things. We {#blank#}3{#/blank#} give the Earth a lot. {#blank#}4{#/blank#} some of the things are not good.

    In {#blank#}5{#/blank#} , when something dies, other animals and plants get food {#blank#}6{#/blank#} it. Every animal or plant gives food to other animals or plants. However, animals can't get food from many of the things that we give the Earth. Animals and plants can't eat metal（金属）, plastic（塑料）and glass. These things will {#blank#}7{#/blank#} in the ground for many, many years.

    Some things are very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals（化学制品）in the water, the plankton（浮游生物）will die. If there isn't any plankton, many animals have {#blank#}8{#/blank#} to eat.

    So what can we do? Don't leave any rubbish（垃圾）in the countryside! Don't make so much rubbish!
