The Earth has warmed by about half a degree（0.50℃）over the last 100 ye
ars.
It could be getting warmer on its own, but many scientists think that people
are making the Earth warmer by making a greenhouse effect. The greenhouse
effect is important. Without it, the Earth would not be warm enough for
us to live on. But just a little warmer than it is now could cause problems for
humans, plants and animals.
Many of the things we do every day can change the
Earth’s
temperature by sending greenhouse gases into the air. We send greenhouse gases
into the air when we watch TV, turn on lights, dry hair, play video games, wash
or dry our clothes or drive cars. The rubbish from factories and homes also
produces greenhouse gases.
Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water.
The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals.
Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don’t do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world.

If you have failed in the past to try to make big changes in life, try again now, one tiny step at a time.
Every year it's the same. As December comes to an end, you think about the new year and all the ways you want to improve your life. But as you start to write down your hopes for the new year, you think about the last year. You excitedly write down all the changes you are going to make, but by the end of January those ideas get lost in your busy life.
Here's a suggestion: Forget the too big, hard-to-achieve goals and just think about the small ones. “We often think that we have to do everything in big steps, even though it's so hard for us to reach it.” said Robert Maurer, who recently wrote the book One Small Step Can Change Your Life. “What we try to do is to begin with such a small step that we can’t find any excuse not to do it.”
“Kaizen”, a Japanese word, is used to mean to change behavior and attitudes (态度). During World War II, American factory managers were able to increase productivity by trying small, continuous improvements instead of sudden changes. After the war, the idea was brought to a rebuilding (重建) Japan. It made Japan develop fast. The Japanese called it “kaizen”, which means “improvement”.
Maurer studied the idea and did some experiments with it. “Kaizen” could possibly help people succeed in doing everything.
1.At the end of December, people usually ___________ .
A. plan for the last year B. fail to make big changes
C. try to lose their ideas D. think about the new year
2.Robert Maurer wrote a book to tell us ___________ .
A. we should do everything in big steps
B. how to find a small step without any excuse
C. we should try a lot of sudden changes
D. how to change one’s life with one small step
3. The underlined part “increase productivity” in the passage means “___________ “.
A. 增加成本 B. 提高待遇 C. 提高生产率 D. 增加出口量
4. The writer of the passage suggests we should ___________ .
A. take a tiny step to achieve big goals
B. make changes at the end of the year
C. do few experiments with “kaizen”
D. do things with hard-to-achieve goals
5. Which of the following is TRUE according to the passage?
A. You can't find any excuse not to reach a big goal.
B. You can achieve your goals if you are not too busy.
C. ”Kaizen” was brought to Japan during World WarⅡ.
D. Robert Maurer studied “kaizen” and found it helpful.

There are many wetlands (湿地) in China and some of them have become the world's important wetlands.
The Chinese Yellow Sea Wetlands are among them. They
are in Yancheng, Jiangsu Province. They are home for many different kinds of
birds and animals. The world's largest Milu Deer Nature Reserve (自然保护区) is in them. More than 700 Milu de
er
live freely there. There are not many red-Crowned cranes in the world, but
every winter you can see some in the red-Crowned Nature Reserve in the Yellow
Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife (野生动物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.
1.The Chinese Yellow Sea Wetlands are in the west of China.
2.Usually the weather in the wetlands is pleasant.
3.February 2nd is the world's wetlands Day.
4.We must protect wetlands only because they can offer food to the animals and birds.
5.Wetlands are valuable resources of land on the earth.
