这是一篇宣传环保的短文,内容介绍新泽西哈特威尔市卡蓬湖三十年前后的变化.三十年前湖畔鸟、兽成群,湖中游鱼成线;而现在由于污染所致,明镜的湖水成了暗褐色的泥浆,杂草丛生.那么如何才能恢复原貌呢?请看下文:

  Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals and fish. The lake water is polluted(污染的). It is in a colour of dirty brown, and it is filled with strange plants.

  How did this happen? First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.

  Now there are many homes around the lake. People often use chemicals(化学品) in their gardens. They use other chemicals inside their houses for cleaning or killing insects(昆虫). There are also many businesses. Businesses use chemicals in their machines or shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake. "They pollute the water and kill the animals.

  Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas(油和汽) from boats often get into the lake. So more bad chemicals go into the water this way.

  People in Hartwell are worried. They love their lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground. And they mustn't use motorboats any more on the lake. All these may change people's lives. Only then can Lake Ponkapog be a beautiful, clean lake again.

1.In the past, the water in Lake Ponkapog was made clean by ________.

[  ]

A.forests
B.rain
C.birds
D.fish

2.Chemicals from homes and businesses ________.

[  ]

     Trees are one of the oldest "citizens (公民)" of our Earth. They keep our air clean, reduce noise pollution,
improve water quality (质量) and provide food and building materials.
     Just like us, trees change a lot as they grow. At l to 3 years old, young trees learn how to protect
themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have
large, deep green leaves so that they can catch enough sunlight and change it into their food and energy.
     当小树成长到四岁的时候,它们成长开始加速并且变得足够强壮以面对未来生命中的挑战。  At the
age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.
    It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. Not
only does the adult tree give us shade, oxygen (氧气) and natural beauty; it is also a great place for a tree
house, or a place for us to nap, read a book, listen to music or sip.(小口喝) tea. If we give the adult tree
proper care, it will continue to live healthily for many years.
     Gradually (渐渐地), trees begin to grow older and older and even die. At this time, they still have their
important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it provides a
home to small animals' and is a source of food for many other animals.
    In many ways, the life of a tree is similar (相似的) to our own life experience. When we are looking at the
life of a tree, we learn about that each period of life brings its own form of joy and challenge. Enjoy every
minute of the life of the trees and take care of the trees!
1. How do young trees protect themselves? And why do they have large, deep green leaves?
    ___________________________________________________________________
2. Why should we enjoy every minute of our own life?
    ___________________________________________________________________
3. 将文中画线的汉语句子翻译成英语。(一空一词)
   When trees are 4 years old, they begin to grow very rapidly and become ______ ______  to face
    challenges later in life.
4. 将文中画线的英语句子翻译成汉语。
