Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt (被状物) over a city. This kind of quilt is called smog.
Many countries are making rules to fight pollution. Factories must clean their water now before it is thrown away and they mustn’t let dirty smoke go into the air.
We need to do many other things. We can put waste things in the dustbin and not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

【推荐1】Our school is a green school. What makes it green?
First, we have a lot of trees. There are trees in front of and behind every building. Some trees are green only in spring and summer. And some are green all year round. The trees make our school look like a big forest.
And our school is a green one also because we “go green”. How do we go green? We have two green days every month. On green days, no students or teachers go to school by car. And we have Clean-up Day every month. That day, students go to streets to pick up rubbish (捡垃圾). Also, we have Tree-planting Day every spring. We plant young trees on hills. We have three Green Clubs. The members of the clubs look after those trees well, like watering and fertilizing (施肥) them.
Green is not only a color, but also about life. Please go green with us and make the world a more beautiful place.

【推荐2】Recycling has become more and more important. As time goes by, it is rapidly changing around the world.
More goods will be made of reused materials. You’ll find more clothing, toys, park benches that are made of recycled water bottles. Buildings and furniture are made of renewable wood and steel.
Consumers (消费) will become cleverer. Shoppers will turn to companies that produce green products.
Less plastic packaging (包装). We find it difficult to open a bottle of pills or a new toy and its a waste of resources. Don’t use plastic bags when we go shopping.
Actions speak louder than words. Waste is finally treated as a material. Companies should make efforts to reduce materials for packaging as well. The government will take measures to change the situation. In the next ten years, we’ll still have a long way to go.
A.Do you pick up plastics every day? |
B.We should take a cloth bag instead. |

【推荐3】David Katz was sad about all the plastic(塑料)going into seas. To help stop the problem, he had an unusual idea -the “Plastic Bank”
Mr. Katz believes that one of the main reasons for plastic going into seas is that people think plastic is worthless. In poor countries, people are working so hard just to get enough food to eat, to find a place to live, and to keep themselves healthy. They don’t have time to recycle(回收利用) plastic.
The "Plastic Bank "helps the poor people solve their problems with food, houses, and health. When people recycle plastic, "Plastic Bank " pays them for recycling it
The program began in 2015 in Haiti, a poor island nation with big problems with plastic. Haiti doesn't have good programs for recycling. People just throw away plastic. It runs in rivers and seas.
“Plastic Bank” opened about 30“markets”in Haiti. At Plastic Bank markets, people can exchange(交换) the plastic they collected for money or other things they need.
The “Plastic Bank” has programs in Haiti, the Philippines, and Brazil. In the Philippines, the “Plastic Bank” works to create “Plastic Bank markets” at 1, 000 gas stations around the country.
So far(到目前为止),the “Plastic Bank” has kept about 7 million pounds of plastic out of seas.

【推荐2】On the evening of September 26th, the streets of Geneva in Switzerland went dark. This usually happens when there is a problem with the electricity, but this time the lights were turned off to allow people to go outside and look at the stars. This is often impossible in a city because of light pollution.
Light pollution is caused when light from streetlights or buildings makes the night less dark. There are many reasons why this is a problem. Animals sleep less because they think it is still the daytime. Birds that fly to warmer countries in the autumn need to see the moon and stars to find their way, but light pollution makes this difficult. Insects and birds in cities often fly towards lights at night. They knock into buildings and die.
Light pollution is also detrimental to us. It can stop us sleeping and give us headaches. Also, we don’t see the same sky that people in the past did. This means we almost never see one of the greatest scenes in the world; millions of stars. Hundreds of thousands of people have never seen it in their lives.
However, it is not difficult to do a few things to reduce (减少) light pollution. We can all turn off lights when we don’t need them and we can cover our windows. If there is less light pollution, we will once again be able to enjoy the beauty of the night sky.

Passenger ships, trade ships, and fishing boats are a normal part of life on the open sea. However, all their activity creates a great deal of noise underwater. Scientists from the United States and Canada recently reported their observations (观察) that the ocean is getting noisier.
Scientists at the University of Victoria have studied the recordings recorded with equipment placed underwater near the busy shipping lanes off Vancouver Island in Canada. They say engine(发动机) noise is continuous during the day, and a little less strong at night.
Scientists say it is likely that whales must call out more loudly to be heard over this noise. The noise could make it more difficult for orca whales to find food. The orcas find fish by producing clicking sounds and other noises. Loud engine noise could be interfering with their efforts.
Michael Jasny is a policy expert for the Natural Resources Defense Council. He says the rise of underwater noise is limiting the ability of whales to communicate.
Shipping noise falls across the same frequencies (频率) that these animals use for all their vital(重大的,紧要的) behaviors — for feeding, for finding mates, for avoiding predators (捕食者) and for going ahead.”
Mr. Jasny says sound travels very effectively underwater. And it is not just whales he is worried about.
“The whole web of life in the oceans depends on sound. And as more and more research has been done, it’s been very clear that what we have on our hands is really a major problem. It’s a serious problem. It’s a global problem. Fortunately, in shipping we have a problem that has a solution.”
One answer is to design quieter ships. America’s National Oceanic and Atmospheric Administration, or NOAA, has four new ships that are made to be quieter. Michael Bahtiarian works for Noise Control Engineering, the company which helped design the boats.
Mr. Bahtiarian says the main source of noise pollution is the propeller(螺旋桨). Better shaped propellers and ship designs can help to reduce noise. NOAA’s ships also have costly engines, which produce less noise. Mr. Bahtiarian says the technology to make quieter ships does exist and has been used in the army for some time.

【推荐1】Around the world, people are more and more worried about the environment. Many people now prefer products and companies (公司) that care about the earth and cause less pollution. This need for green products has led large companies to change their business.
Before, customers used cheap plastic (塑料) bags, and then threw them away. But now most supermarkets and stores usually provide reusable shopping bags for them. This causes less waste. They also offer more local products, because less energy is needed for carrying them one place to another.
To help lower air pollution, big car factories are looking for other ways to control the amount of oil. Cars that use much less oil are very popular. Many companies are also developing fully electric cars. They produce no air pollution at all. Both kinds of cars have another advantage: They are cheaper to run and people don’t need to worry about oil prices.
The airline companies face an even greater green challenge. Airplanes use much more oil than cars. So many airlines are now developing planes that can run on some other kinds of oil. They create less pollution and cost less. The companies are also developing a new kind of planes, and some of them use only solar panels (太阳能板) to fly!
Green businesses used to be popular with only a small group of people. But now, more and more companies have to show they care about the environment. Many products are marked “green” in order to look nice. However, people still have to be careful when choosing green products. It’s important to make sure that products are as environmentally friendly as the businessmen say.
1. What does the word “them” in Paragraph 2 refer to?A.Local products | B.Reusable shopping bags | C.Cheap plastic bags |
A.show the green products are healthy |
B.tell people to choose green products carefully |
C.explain the importance of the environment |
