2 . An environmental group in Colombia is leading a project to save wild areas in the San Lucas Mountains with the help of coffee growers.

Since 2016, San Lucas areas have been threatened by mining and coca (古柯) planting Gold miners and coca growers make more money than coffee farms. Now the group WebConserva helps link coffee farmers with coffee processors from around the country in order that they can earn more. At the same time coffee farms can serve as boarders around the forests to protect the biodiversity within.

To date, the project includes 10 families who farm 400 hectares of coffee plants. WebConserva said it hopes, in time, 200 families will be included. At that level. 20,000 hectares of untouched forest could be protected. The families promise not to cut down trees to expand their crops or to hunt wild animals. In return, they receive $300 for 125 kilograms of coffee.

Arcadio Barajas is among those taking part. His coffee farm sets up a barrier between cattle farms and forests where wild animals live, thus reducing the possibility of conflict between cattle farmers and wild animals.   “Cutting down the forest to plant coca and killing wildlife were against my faith, and now I feel that growing coffee lets me be a good guard of the land,” he said.

Amnobis Romero is a former coca grower and miner. “Many families depended on illegal activities to support their children years ago. Now, we feel it a duty to look after this biodiversity and leave it for future generations,” he said. Activists want San Lucas to be protected as a national park, but the process has been slow. Carlos Valderrama, director of Webconserva, hopes the project can build production system that will last far into the future. “It protects forests, biodiversity and ecosystems at the same time as improving coffee growers’ quality of life,” he said.

It’s really nice to see a lot of Tibetan antelopes (藏羚羊) on the green grass. However,     1     (they) population dropped by more than 50% during the 1980s and 1990s. To make profits, some people were shooting antelopes. The habitats     2     the beautiful animals lived were becoming smaller as new roads and railways     3     (build).

In order to save this species from extinction, the Chinese government placed it under     4     (nation) protection. Many volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move     5     (easy) and keep them from     6     (car) and trains.

Gradually, the antelope population has recovered and     7     June 2015, the Tibetan antelope was removed from     8     endangered species list. The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelopes have not yet disappeared.

In a word, if we want     9     (save ) the planet, we must change our way of life. Only when we learn to exist in peace with nature can we stop     10     (be) a threat to wildlife and to our planet.

4 . The earth has many mysteries for people to explore and we live on the earth for protection. Do you know that the earth has two North Poles? There’s the geographic North Pole, which never changes. And there’s the magnetic (有磁性的) North Pole, which is always on the move. Over the past 150 years, the magnetic North Pole has casually wandered 685 miles across northern Canada. But right now it’s racing 25 miles a year to the northwest. This could be a sign that we’re about to experience something humans have never seen before: a magnetic polar flip (翻转). And when this happens, it could affect much more than just your compass.

Right now on the surface of the planet, it looks like it’s just a bar magnet. Our compasses are just pointing to one pole at a time because there’s mainly a two-pole system. But sometimes, the earth doesn’t just have a single magnetic North and South Pole. Evidence suggests that, for hundreds to thousands of years at a time, our planet has had four, six, and even eight poles. This is what has happened when the magnetic poles flipped in the past. And when it happens again, it won’t be good news for humans.

Now you might think, eight poles must be better than two. But the reality is that multiple magnetic fields would fight each other. This could weaken the earth’s protective magnetic field by up to 90% during a polar flip.

The earth’s magnetic field is what protects us from harmful space radiation which can damage cells and cause cancer. With a weaker field in place, some scientists think this could expose planes to higher levels of radiation, making flights less safe.

This could also interrupt the internal sense of direction in many animals that use the magnetic field for navigation (导航). Even worse, it could make certain places on the planet too dangerous to live in. But what exactly will take place on the surface is less clear than what will undoubtedly happen in space.

Satellites and space missions will need extra shelter that we’ll have to provide ourselves. Without it, intense universal and solar radiation will fry circuit boards and increase the risk of cancer in astronauts.

1. Which of the following can best describe the earth’s magnetic field?

A．The focus of scientific research.	B．The navigation of satellites.
C．The center of the universe.	D．The protective umbrella of humans.

2. What will some animals be faced with when the magnetic poles flip?

A．Losing the ability to hunt for food.

B．Bearing very loud noise day and night.

C．Being unable to find directions exactly.

D．Being unable to protect themselves from danger.

3. What can we learn from the text?

A．Astronauts are more likely to suffer from cancer.

B．The magnetic North Pole is moving faster than before.

C．Flights aren’t allowed to travel as usual when the magnetic poles flip.

D．There are always more than two magnetic poles on the earth at a time.

4. What may be the best title for the text?

A．What will happen when the poles flip?	B．The ways that scientists research poles
C．How and when will the poles flip?	D．The reasons why scientists research poles

5 . Who will probably take care of the dog?

A．Nancy.

B．Jason.

C．Mark.

6 . Why does the woman seldom go to the zoo?

A．She dislikes the animals’ smell.

My aim in life is     1     (protect) the environment for future generations. I want to become     2     environmental consultant after graduation. Many people think that pollution cannot     3     (stop) if we want the country to develop. But that is not true. We can cut back on     4     (danger) and dirty waste from factories. Although a factory produces a large quantity of goods, it does not mean that it has to pump a lot of pollution into the environment. I also want to teach people to buy products     5     have been recycled. This is much     6     (good) for the environment, because it means we do not need to cut down many trees.Companies and businesses can still operate,     7     the Earth will not have to suffer.

There is no     8     (debate) that we also have a problem with population. The number of people in the world keeps growing, and we    9     (produce) more rubbish and using up more raw materials. What if they run out? I am confident that if we are all willing     10     (work) together, we can overcome these challenges and keep the Earth clean and healthy.
