Around the world there is an increase in the demand for reforestation. This is because the consumption of the forests has affected not only the animals living in the area but also the people. And reforestation is about the rebuilding of the forests that have been severely destroyed. It can offer a lot of benefits when the recreation is successful.

1.This includes collecting seedlings(幼苗) that are native in the area to make sure that there is a natural reconstruction of the area. Some additional trees which are not native in the area also need to be planted.

2.The importance of having multiple species of trees is considered to make sure that the needs of other species that will live and grow in the area are met.

Destroying a forest is easy but rebuilding it is really hard.

3.The plan must include accurate spacing on plants and trees. This is to ensure that they won’t cover each other while they grow.

4.The forest greatly helps in the reduction of the air pollution. Trees are responsible for the production of oxygen and absorption of carbon dioxide.

5.It is there for a reason just like everyone else on this planet.

There cannot be a better way to restore the balance of nature than to increase the forest area. We must remember that the forest is a natural habitat of wide variety of animals and plants. In this manner, there is no substitute for reforestation.

A. And global warming will speed up the destruction of forests.

B. Keep in mind that you can’t just plant the seedlings anywhere.

C. Recreations won’t work until all these details have been considered.

D. So a good plan is needed to make the reforestation a successful one.

E. The forest also protects us from typhoons and other natural disasters.

F. There are many things to be done when it comes to this type of effort.

G. It is important to make sure that they are suited to the climate and the type of soil.

Governments all over the world make public reports about the condition of their economies. Most countries, including the United States, have used a measure called the gross national product (国民生产总值)or GNP. It includes all goods and services produced by citizens of the country anywhere in the world.

Recently the American Commerce Department has started using a new method to measure production. It is known as the gross domestic product（国内生产总值）or GDP. It counts only goods and services that have been produced within the nation’s borders. Money earned by foreign companies operating in the United States is included in the GDP, but money earned by American companies operating in other countries is not.

Economic experts generally approve of the change. They say that the gross domestic product provides a truer measure of the economy. They also note that most other industrial countries use this method. Therefore it will be easier to study the economies of different countries. Some officials also hope the new system will help them make better economic policy decisions. It will provide them with a clearer understanding of economic activity in the U.S. . The new measure is less likely to be affected by sudden changes in foreign oil prices or in the value of the American dollar in other countries.

Economic experts believe that the change from GNP to GDP will immediately reduce the value of American production by at least 40,000 million dollars a year. But that is really a very small change in the American economy – less than 1% . The Commerce Department reports the unofficial gross domestic product once every three months. The government also continues to report GNP as it has four times a year since 1941.

1.To report the American GNP, the government should not consider goods and services produced _______.

A. by American companies at home

B. by American companies in China

C. by American companies in Singapore

D. by Japanese companies in the United States

2.To report the American GDP, the Commerce Department should count money earned ________.

A. by both American and foreign companies in America

B. by American companies within its own borders

C. by foreign companies in the United States

D. by American companies in its foreign markets

3.GDP is considered better than GNP by some economists because ________.

A. it is something new

B. it is used by most countries

C. it is easier to calculate

D. it is less likely to be affected by the foreign market

4.What will happen to the value of American economy if GDP is used to replace GNP?

A. It will be seriously affected.                B. It will not be affected.

C. It will come down a little.                   D. It will slightly go up.

5.How often are the reports of GDP issued by the American Commerce Department?

A. once every four months                           B. once every three months

C. once every six months                   D. once a year

Around 45% of plastic waste is recycled annually in the UK and is on the increase. However, one of the problems with present plastic recycling methods is that you end up with a lower-quality plastic with worse properties （特性）than the original. This means that plastic drink bottles cannot simply be recycled into new drink bottles continuously, but instead are used for other lower-grade products like park benches.

Now, British scientists have developed a new method of chemical recycling. They use lower temperatures and more environmentally-friendly starting chemicals than previous methods to turn plastics back into their constituent chemical molecules （分子）.In this way, they can be used to make new plastics of the same quality as the original.

"Most plastic is now recycled using mechanical methods, where they are transformed into liquids before being made into something new," said a professor named Matthew Jones. "The problem is, melting plastic changes its properties and reduces the quality. Out method of chemical recycling overcomes this problem. Then plastics can be used all over again without losing any properties?"

The researchers are recycling some kinds of plastics, including plant-based PLA, a plastic used for food packaging and PET, which is used for drink bottles. So far, the technology has only been demonstrated on a small range. However, scientists are now working to produce larger quantities of starting chemicals.

"There is no single solution to the problem of plastic waste — the approach has to be a combination of reducing, reusing and recycling. Our method of chemical recycling could allow carbon to be recycled endlessly rather than digging more up from the ground in the form of fossil fuels, or letting it into the atmosphere as a greenhouse gas," said Dr. Paul McKeown from the University of Bath.

1.What is the problem with the present plastic recycling?

A.The quality of recycled plastics declines.

B.Plastic drink bottles cannot be recycled.

C.The amount of plastic waste is increasing.

D.Recycled lower-grade products sell badly.

2.How do scientists recycle plastic waste with the new method?

A.By transforming it into fuels.

B.By heating it into liquid state.

C.By keeping its original properties.

D.By changing its molecule structure.

3.What can we learn from what Dr. Paul McKeown said?

A.Fossil fuels are endless resources.

B.The plastic waste problem has no solution.

C.Recycled carbon leads to greenhouse gases.

D.The chemical recycling is environment-friendly.

4.In which part of the website can we find the text?

A.Business. B.Tech & Science.

C.Lifestyle. D.Arts & Culture

Even a small increase in light activity such as washing dishes, or walking around the house might help prevent an early death among older adults, researchers say.

“It is important for elderly people, who might not be able to do much moderate intensity（强度）activity, that just moving around and doing light intensity activity will have strong effects and is beneficial,” said Ulf Ekelund, who led the research.

Published in the BMJ, the latest research was based on a review of eight studies involving a total of more than 36,000 people with an average age of almost 63 years. Participants were followed for five to six years; 2,149 deaths were recorded. All of the studies involved monitoring the physical activity of individuals who had activity trackers, and the studies did not rely on self-reporting, which, the experts noted, could be unreliable.

For each study participants were split into four equal-sized groups, based on the total amount of time spent actively, and the risk of death assessed, taking into account factors such as age, sex, body mass index, and socioeconomic status. This was then repeated for an amount of activity at different levels of intensity. The results were analyzed together to give an overview. The team found a greater amount of activity was linked to a lower risk of death. The results held for different intensities of activity. The team said the study supported the message “sit less and move more and more often”.

However, the study had limitations. It only looked at the situation for middle age and older adults, most of whom lived in the US or Europe, and some of the effect could be due to those people with a higher risk of death being less likely to be related to physical activity. Physical activity levels also were only measured over one period of time.

Dr Gavin Sandercock, from the University of Essex, said the results suggested moving more brought bigger benefits than simply reducing the time of sitting, another factor measured in the study.

“This study reinforces the important message that getting the least active people to do even just a little bit more physical activity can have important public health benefits,” he said.

1.Which of the following may Ulf Ekelund suggest elderly people do?

A.lying on the sofa reading.

B.Doing a little gentle gardening.

C.Going out to hike with friends.

D.Playing basketball sometimes.

2.What can we know about the research?

A.It lasted about 8 years.

B.The researchers admitted they used fake data.

C.The participants didn't include younger people.

D.Some participants died because of doing too much physical activity

3.What is the author’s attitude towards the researchers' conclusion?

A.Doubtful B.Critical

C.Supportive D.Neutral

4.Which of the following is closest in meaning to the underlined word “reinforces” in the last paragraph?

A.Highlights B.Conveys

C.Excludes D.Denies
