【推荐1】How green are you? Do you know how to be green?

We all need a healthy environment, but we produce waste every day and it often results in lots of pollution. In fact, even the simplest everyday activities can make a difference to the environment. Here are some ideas for you.

Reduce. It means “use less”. It suggests people should produce less pollution and throw less rubbish. People should reduce waste by buying fewer things. So before we are going to buy a new thing, try to think whether it is really necessary for us.

Reuse. Reuse means “use again”. It asks people to use things as long time as possible. When we buy things, guarantee that we really need them and we can use them for a long time. We should value them so that we can use them for a longer time. And if we can, we should repair (修理) them instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. If we can use a china (陶瓷) up or a lunch box, we are doing something green and helpful.

Recycle. Recycle means “use in a new way”. Many people encourage people to recycle things. Look at these examples. People often recycle old or waste electrical things and try to create some new things with some parts from the old ones. Second, some people try to make some bags with old clothes. At last, people often clean the house or water plants with used water.

【推荐2】I am a plastic bottle. A week ago, I was on a supermarket shelf.     1     I felt really happy.

Then a tall woman picked me up and put me in her basket! The woman took me home and put me in the fridge. It was cold, but I soon made friends with the cans and bottles in it. However, only a few hours later, she took me out of the fridge and drank the water inside me.     2     I have never felt so empty and alone in my life.

Early the next morning, a man took me out of the dustbin. He threw me and the other rubbish into the back of a truck.     3     Then I was pushed together with the rest of the rubbish. Soon I was completely flat(扁平的). I can’t believe how thin I became.

I slept for a while.     4     Everything around me was ugly and had bad smells. I felt afraid. I kept hoping that I would be moved somewhere else. Finally, huge trucks came and covered us with something.

    5     She said that we would never leave this place, but would have to stay here for thousands of years.

“Why can’t they recycle us?” I cried.

【推荐3】The world’s largest rainforest, the Amazon rainforest(亚马逊雨林), covers 40% of the area of South America. It makes about one fifth of Earth’s oxygen(氧气). People call it “the lungs(肺) of our earth”.

However, the Amazon rainforest is in danger now. A large fire happened there. It lasted for 22 days and ended on August 27, 2019. In fact, there are a large number of fires in the rainforest this year. Between January and August, there were over 74,000 fires. Most of the fires came from people’s activities. Farmers in the Amazon rainforest use fire to prepare for planting for many years. But what they do is dangerous because these fires can easily get out of hand.

By now, the fire has been put out. But scientists say it will take about 20—40 years to build the forest’s ecosystem(生态系统) again. The fire also burned plenty of trees. Without trees, many animals lost their homes because of the fire, such as monkeys, birds, sloths and so on. The Amazon river is also polluted. Air is not clean any more. The Amazon rainforest is our home. Let’s protect it and repair(修复) the ecosystem together!

【推荐1】The webs that spiders build to catch insects seem weak. However, the strength of spider thread is greater than steel (钢铁). Webs can even stand up to very strong storms.

In each spider web, some threads are sticky, but some are not. When a spider is moving on the web, it will not step on the sticky threads. After a time the silk will lose its stickiness and become unable to catch insects. Then, spiders usually eat their own web.

Now a team of scientists has worked out why the spider web is so strong. It is not just the strength of the thread, but the clever design of the web. “The key to a web’s success is its ability to keep its shape and strength even after some of the threads break,” said scientists at the Massachusetts Institute of Technology (麻省理工学院). The scientists found the thread itself has the ability to become softer or harder. So it can hold different types of heavy things.

In tests, scientists used three other strong materials made into the same webs. The spider thread was six times stronger than any other material. More surprisingly, when the scientists took away up to 10 percent of the threads from different places, the web didn’t become any weaker. Actually, it became up to 10 percent stronger.

The spider web’s clever design gives scientists many new ideas. The findings could help design safer buildings and even a new type of strong material. “It’s a really good chance,” said Markus Buehler, a professor at MIT.” It may give us some new ideas for engineering.”

【推荐2】People use languages to communicate. Any language has its ways to express people’s minds. One of the ways in common is the use of idioms. An idiom is a group of words. It has a special meaning that is different from the usual meaning. For example, “under the weather” is an idiom meaning ill. So when people say “I’m under the weather”, they are saying that they’re not feeling well. Another example, “in all weathers” means “in all kinds of weather”. So, “There are homeless people sleeping on the streets in all weathers” tells us that homeless people sleep on the streets no matter whether it is cold or hot.

Different languages may have different ways to make idioms. For people who are learning a foreign language, idioms could cause misunderstandings and bring them endless headaches. On the other hand, if things are done right, idioms can also be a fun way of looking into a new culture and understanding how the people think and talk.

Metaphor (比喻) is often used in idioms. Let’s read the following two examples:

●It makes my blood boil (煮沸) when people litter (乱扔).

●The night was dark and quiet; my blood ran cold when I heard a strange noise outside at dark night.

In neither situation above, our blood can reach the point so high or so low in temperature. Yet, with the situations the two sentences created, it is not difficult to work out the unhappy feelings of really angry in the first example and very afraid in the second.

Of course, not all idioms are this easy to understand. When we come to idioms of a foreign language, a good dictionary of idioms is always suggested.

1. This passage tells us something about ________ in the English language.

A．grammar

B．writing

C．reading

2. If your brother breaks your computer, you can say to him, “________”.

A．I’m under the weather	B．I’m there in all weathers

3. What is the writer’s advice when you come to an expression like “under the weather”?

A．We should look it up in a good idiom dictionary.

B．We should try to express our minds with it.

C．We should find an interesting way to learn it.

D．We should create situations to guess its meaning.

4. What’s the author’s attitude (态度) about idioms?

A．Positive.

B．Negative.

C．Neutral (中立的).

D．We don’t know.

5. We can find the passage in a book about ________.

A．history

Scientists looked for paw prints(爪印) in the forests. In this way, they knew the number of pandas! “It’s hard to see pandas in the wild,” said Colby, a scientist. “They hide in the thick bamboo forests. “That’s why scientists used paw prints to get the number. The number of the pandas was a surprise to Scientists. They learned that more pandas lived in the wild!

“We found pandas living in areas we didn’t know,” said Colby. Although the news is good, pandas are in danger.

Here are some fun facts of pandas:

It takes a panda more than 10 hours to eat 9 kg to 14 kg of bamboo every day.

A newborn panda weighs 90-130 grams. That is about the weight of a mouse. A panda’s front paws have wrist bones(腕骨). The panda uses them to catch bamboo.

The main threat to pandas is that their land is becoming smaller and smaller. Pandas lose their land when people cut down parts of the forest for wood and farming. Now, China has13 nature reserves(保护区). People mustn’t cut down trees there. Scientists want to create more nature centres to give pandas a better chance to live.

【推荐3】Crested ibises (朱鹮) are one of the oldest bird species (物种) on Earth. It is believed that they have been around for 60 million years. They were once common in Asia. But in the 1960s, they began to disappear because of pollution and other human activities. In 1981, Chinese scientists found seven of them in the wild in Yangxian, Shaanxi Province. They were believed to be the last ones in the world. But now, they have been saved from extinction.

Researchers say its population has risen to more than 5, 000 around the world. There are 3, 000 crested ibises in Yangxian alone. The birds’ survival (幸存) is because of China’s early protection efforts, according to Zhang Yueming, an expert who helps protect the birds in Yangxian.

On the fourth day after finding the ibises, the local government put up a lot of notices to protect the birds. Then, it stopped people from cutting down trees. Later, it set up the Qinling No. 1 protection station and sent four people to look after the birds day and night. During the daytime, they watched and recorded the birds’ habits and conditions. At night, their job was to keep them safe.

To help the ibises have more babies, a rescue and breeding center (救助和繁育中心) was set up in 1990. At the center, crested ibises are fed by people and can receive timely help when they are sick or hurt. China’s protection of crested ibises is an example in the world's history of protecting endangered wildlife.
