After David's daughter was born, he decided to make one million dollars. He thought in this way his daughter would live {#blank#}1{#/blank#} happy life.

    In order to achieve his goal, David devoted most {#blank#}2{#/blank#}his time to his business. While other fathers {#blank#}3{#/blank#}(play) with their kids outside, he was working. While other fathers were reading stories to their kids, he was hanging out with his clients(客户). His little daughter {#blank#}4{#/blank#}(name) Jane hardly saw him.

    Time flew fast. One day, when David returned home from work, he saw Jane {#blank#}5{#/blank#}(sit) in the living room. When she saw him, she ran to him and asked him to play with her for a while. “Sorry, Jane, but I'm {#blank#}6{#/blank#}(terrible) busy tonight. I have a lot of work to do.” He was about to leave {#blank#}7{#/blank#}he heard Jane crying. So he stopped and asked why. “You're always working. You have no time for me at all. You're not a good dad,” said Jane. David was {#blank#}8{#/blank#}(lose) in thought after hearing that. He remembered why he worked so hard — he wanted Jane to live a happy life. However, things go contrary to his wishes. He {#blank#}9{#/blank#}(teach) a good lesson that day. Therefore, he made a {#blank#}10{#/blank#}(decide) to spend a lot more time with his daughter.

    With the{#blank#}1{#/blank#} (develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because {#blank#}2{#/blank#}air pollution. Air pollution is caused by the following {#blank#}3{#/blank#}(reason): about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off {#blank#}4{#/blank#}(poison) gases. 25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health {#blank#}5{#/blank#}to others. {#blank#}6{#/blank#}these, about 10%of air pollution is caused by other reasons. We should take some measures to fight {#blank#}7{#/blank#}pollution. New fuel can be used to take {#blank#}8{#/blank#} place of gas. We can plant more trees. If everybody realizes the{#blank#}9{#/blank#}(important) of environment and does something to stop pollution, the problem will {#blank#}10{#/blank#}(solve).

    Babies are great and lots of fun. We all love babies and we need babies, too. Many countries don't have enough of them. That's a big problem.

    Most babies grow up to become workers. As the number of workers {#blank#}1{#/blank#} (grow), a country can produce more things. That often means people's lives become easier and more {#blank#}2{#/blank#} (comfort). But without enough babies, a country {#blank#}3{#/blank#} (gradual) gets old. Many countries provide services {#blank#}4{#/blank#} their people like health care. These services {#blank#}5{#/blank#} (pay) for by young working people. But they are mostly used by old people {#blank#}6{#/blank#} aren't working any more. Without enough young people, countries can't afford these things.

    Countries are dealing with {#blank#}7{#/blank#} problems in different ways. Many countries are encouraging people {#blank#}8{#/blank#} (have) more babies. Since raising children is expensive, some countries give families extra money. Some other countries change rules {#blank#}9{#/blank#} it is easier for mothers to study and work. Others are welcoming immigrants (移民) from other{#blank#}10{#/blank#} (place). How do you think this problem should be solved?
