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!

sighted, a research shows. It challenges (挑战) the belief that short-sightedness is caused by computer use,
watching TV or reading in weak light.
The Australian government researchers believe that sunlight is good for people"s eyes. They compared
the vision (视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the
Singaporean children were short-sighted-this rate (比率) was ten times higher than Australian children.
Both groups spent a similar amount of time reading, watching television and playing computer games.
However, the Australian children spent an average (平均) of two hours a day outdoors-90 minutes more
than the Singaporean children.
Professor (教授) Ian Morgan, from the Australian Research Council"s Vision Centre, said, "Humans are
naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number
of short-sighted people gets larger. We"re also seeing more and more short-sighted children in cities all around
the world-and the main reason may be that city children spend less time outdoors."
Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from
becoming short-sighted? Scientists believe that natural light has a special chemical (化学物质) which stops
the eyeball from growing out of shape and prevents people becoming short-sighted. So be outdoors. It doesn"t
matter if that time is spent having a picnic or playing sports.
B. 90 minutes.
C.1 hour.
D. 30 minutes.
B. Why natural light has a special chemical.
C. Why playing outside is good for one"s eyesight.
D. Why daylight is much brighter than indoor light.
B. Playing outdoors for 2 or 3 hours every day can help protect your eyesight.
C. Children in Australia are more likely to get short-sighted than those in Singapore.
D. If you spend two or three hours playing outside each day, you won"t get short-sighted.
environment. So they set up Earth Day to tell everyone about their worries.
In 2007 organizers m over 150 countries planned over 4,000 big events. But Earth Day is not just about
marches (游行) and big events. In the week around Earth Day (22 April) there were many thousands of
smaller, local events. These events dealt with environmental problems in the neighborhood.
The World Wide Fund for Nature made a list of 5 things that each person could do to save the environment.
* Don"t leave the tap running.
* Turn off lights when you leave a room.
* Turn off your computer every night.
* Wash your clothes, and yourself, in warm or cold water, not hot water.
* Dishwashers use as little water as possible. If we all do at least 2 0f these all the time, we can make a big
difference.

go round in one way. Some in many ways.

Virus travel from one person to another in many ways. Some diseases are carried by insects, such as flies
and mosquitoes (蚊子).
Larger animals can also carry diseases. People can get diseases from dogs or even rabbits. At one time
many people got TB (肺结核) by drinking milk form cows that had the disease. Today, milk is made safe. The
milk is heated and made cold.

of only 65 kilometers per hour.
The cars of the future will be fine for getting around a city, but they will not be useful for long trips. If the
car is powered by electricity, it will have two batteries-one battery (蓄电池) for the motor and the other for the
lights, signals, etc. If the little cars run on gasoline (汽油), they will go 450 kilometers before they need to stop
for more gasoline.
If big cars are still used along with the small ones. We must (5)_____ two sets of roads, one for the big,
(6)_____ cars and the other for the (7)_____, slow ones.
