1 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

2 . Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.

On April 22,2011,we decided to be green every single day for an entire year. This meant doing 365 different things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different things to do and this was no easy task.

With the idea of going green every single day a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all green things that could be done to help the environment. We wanted to push the message that every little bit helps.

Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic (有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planets.

A young man called Low­Carbon Brother become a hit on the Internet in 2011. He is still active in protecting the environment. He suggests to living a low­carbon life, which means using less energy in our daily life so that we can help reducing carbon dioxide in the air. For example, she always picks up some waste paper on the street or uses the blank side to write something. While he is watching TV, he always turns up the screen brightness to the minimum and turns off the light. Therefore, he goes to work by bike instead of driving. Some people think what he is doing is just a show. No one can live such a simply life with so many modern invention around us. As far as I am concerned, I am strongly in support his idea and his behavior. Although what he is doing has no huge effect on global warming, but he at least can enjoy a healthy life.

4 . To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn’t a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater.
“Planting trees is one way, but it isn’t that simple. It doesn’t solve the basic issue of water resources,” says Wu Bo, a professor. “We need to calculate how much water the trees will absorb, or else it could have a negative effect.”
Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields（产量） using flood irrigation and earns a good income for his family.
Other farmers haven’t stuck it out（坚持到底）: about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return.
Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight.
“With enough water, this problem can be solved,” Lu says. “We can plant trees and grass, and they will grow bigger. That will stop the desert.”
Experts say that farmers could switch to drip irrigation （滴灌）to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to “Save Water, Protect the Environment”.

A．it can make groundwater become less

B．it can prevent the sand moving freely

C．it can stop crops growing well

D．it can get the soil to become poor

2. Why did Mr. Lu NOT accept the idea of relocation?

A．Because the plan of relocation will cost him much money.

B．Because his family had trouble moving away.

C．Because he was reluctant to give up his land.

D．Because he would rather stay than fight against the deserts.

3. What can we infer from the passage?

A．The deserts drive more and more people to leave their homes for their lives.

B．People have no means to fight against the land becoming desert.

C．Water is the biggest barrier for people to stop the desert.

D．Planting trees cannot solve the problem of desertification of farmland.

5 . Energy goes from one plant or animal to another. A food chain shows how this energy moves. Each time an animal gets eaten, its energy is passed onto the animal that eats it. The food chain is very important because it keeps the balance of nature. If one part of the food chain disappears, it can affect all the other plants and animals. Any threat to the food chain is a threat to the environment’s biodiversit(生物多样性). The food chain helps keep animal populations in balance. However, if something happens to increase or decrease one of the links in the food chain, that balance is broken. If one animal becomes endangered, it puts all the animals above it at risk.
Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment.
A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鳍). Now, not enough sharks are around to eat the cownose(牛鼻) ray. The ray’s population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商业的) fishing.
Many of us disturb the natural environment in our own backyards. It’s up to us to take care of the environment and try not to disrupt the natural food chain. If we don’t act responsibly, animals will start disappearing.
1. What can we learn from Paragraph 1?

A．The food chain is not easy to be broken.

B．The energy of an animal usually disappears when it dies.

C．Increasing the links will not break the balance of nature.

D．Breaking the food chain is bad for the biodiversity of the environment.

2. The study mentioned in Paragraph 3 proves that            .

A．human activities can be a big threat to the food chain

B．we are all responsible for the breaking of the food chain

C．natural disasters are hard to break the food chain

D．hunting large sharks for meat is beneficial

3. We can infer that the writer wrote this passage mainly to           .

A．explain what the food chain is

B．tell us something interesting about Nature

C．suggest that we stop eating meat to save animals

D．suggest that we not disrupt the natural food chain

6 . Everything you do to protect the planet helps all living things, including humpbacks（座头鲸）and other species of whales that live in oceans worldwide. And yes－just one kid, like you, can make a difference.     1    .

Don’t litter. Rubbish thrown away carelessly outside often washes into storm drains（排水沟）, which empty into rivers and eventually flow to the oceans.     2    , including whales.

Say, “No bag, thank you.” Whether you’re buying toys, snacks, or clothes, tell the checkout person you don’t need a bag.     3    , you’ll help reduce the 100 million plastic bags that each year block sewers（下水道）, and get swallowed by whales, sea turtles, and other wild life.

Plant a tree.     4    . They produce oxygen and absorb carbon dioxide（二氧化碳）, a gas that animals, including humans, produce naturally as they breathe. But because carbon dioxide also comes from cars and factories, there is too much of it in the atmosphere, which is contributing to global warming. If everyone planted one tree, those trees would remove a large amount of carbon dioxide from the atmosphere.

    5    . Every time you leave a room for more than a minute, turn off the light you’re using. In this way, you save energy and keep greenhouse gases out of the atmosphere.

Try the family challenge! Many streams and rivers are polluted and littered with rubbish. You and your family can help preserve the waterways by joining others in your community to pick up rubbish.

A．Trees help clean the air we breathe

B．Turn off the light

C．Avoid driving cars

D．By carrying your own reusable bag

E．Treat them like friends

F．Here are ideas for easy small things you can do

G．Pollution is a growing problem for all the Earth’s oceans and its wildlife
