BEIJING-China has seen reduced desertification and increased forest coverage since 1978, thanks to the Three-North Afforestation Program (TNAP).

Constructed in the northeast, north and northwest China, TNAP is a national program fighting against soil erosion and wind-sand damage by planting sand-fixing forests. The area of sand-fixing forests has increased by 154 percent in the past 40 years, contributing to the reduction of desertification by around 15 percent, according to a report jointly released by the National Forestry and Grassland Administration (NFGA)and the Chinese Academy of Sciences.

Over the past 40 years, TNAP increased the forest area by 30.14 million hectares and raised the forest coverage rate from 5.05 percent to 13.57 percent in the regions it covers, said Liu Dongsheng, deputy head of the NFGA.

“China's desertification area has obviously reduced since 2000 due to the construction of the Three-North affor-estation and people's increasing awareness of environmental protection,” said Zhu Jiaojun, head of the Institute of Applied Ecology in the northeastern city of Shenyang. Three-North protective forests helped reduce sandstorms by fixing the sources of sand on the ground, Zhu said.

The program also played a role in preventing sandstorms in the Beijing-Tianjin-Hebei region. Official data showed the time of sandstorms per year dropped from 5.1 days in 1978 to 0.1 days in 2015.

Over the last two decades (十年), the Earth has seen an increase in vegetation (植被) and China and India are leading the increase in greening on land. The result comes mostly from tree planting programs in China and intensive agriculture(集约农业) in both countries.

Researchers from Boston University found that global green area has increased by 5% since the early 2000s, an area equal to the size of Amazon rainforest. Among the increased area, China and India contribute to about 33%, especially China, with 25% itself. China’s great contribution came mostly from its programs to protect and expand forests, which is about 42%. These programs were developed in an effort to reduce the effect of desertification, air pollution and climate change.

Another 32% of the greening change in China, and 82% in India, resulted from intensive agriculture of food crops. The land area used to grow crops in China and India has not changed much since the early 2000s. Yet both countries have greatly increased the total green area and food production in order to feed large populations. The lead author Chi Chen of Boston University said,

“That is a surprising finding, since it is generally believed that land degradation(退化) in populous countries is usually more serious.”

Rama Nemani, a research scientist at NASA’s Ames Research Center, saw a positive message in the new findings. “Once people realize there is a problem, they tend to fix it,” However, the researchers rang bells as well. They pointed out that the gain did not necessarily fill up the loss of natural vegetation in tropical regions like Brazil and Indonesia.

1.What’s the first paragraph mainly about?

A.The earth is becoming a green land.

B.China and India are forest countries.

C.China and India matter in greening the Earth.

D.China and India develop intensive agriculture well.

2.Why is Amazon rainforest mentioned in Paragraph 2?

A.To show its importance to the planet.

B.To call on people to protect rainforests.

C.To clearly show the increased green area.

D.To be evidence of the lost natural vegetation.

3.What benefits can China’s tree planting programs bring?

① Reducing air pollution.　　

② Increasing rich land for crops.

③ Helping with climate control.　　

④ Controlling the desertification.

A.①②③ B.①③④

C.①②④ D.②③④

4.What can we infer from the last paragraph?

A.Brazil and Indonesia do not protect their forests.

B.The findings discouraged belief of a green world.

C.Humans are creative enough to solve all problems.

D.More efforts are needed to protect natural vegetation.

5.Where does the text probably come from?

A.A newspaper. B.A travel brochure.

C.An interview. D.A geography textbook.

There has been a large increase in the number of natural disasters over the past few years, and it is believed that global warming and climate change could cause even more disasters in thefuture. Some of the world’s leading cities are facing disasters like floods and heat waves.

London

London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat (威胁)of flooding, but it was only designed to last until 2030 and close once every two or three years. About 31 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not solved

There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property(财产）in London’s flood risk area, so large scale flooding would be disastrous.

Paris

Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?

One solution is to have air-conditioners installed（安装）in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).

In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.

Shanghai

Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.

About 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption（消耗）. China depends heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.

1.What problem should be settled now in London?

A. How to protect the city’s property

B. Where to build its flood defences

C. How to use the Thames Barrier to protect the city

D. How to improve the function of the old flood defences

2.Which of the following measures can’t solve the heat wave disaster in Paris?

A. Putting up new types of buildings with a covering of bamboo.

B. Having air-conditioners installed in elderly care homes.

C. Forbidding the city to build “Flower Tower”.

D. Encouraging architects to design new types of buildings.

3.The major threats to Shanghai are __________.

A. increasing population and coal-fired power stations

B. rising sea levels and typhoons

C. extremely high temperature and rising sea levels

D. extra demands on energy consumption and typhoons

4.The purpose of the passage is __________.

A. to tell us how to protect the big cities

B. to give advice on how to defend natural disasters

C. to explain what causes flood and heat waves

D. to warn us of the increasing natural disasters in big cities

The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.

As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.

Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.

Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.

One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.

1.Before the experiment, volunteers ______.

A．are gathered and take a training

B．cannot eat or drink for several hours

C．must wash their hands carefully

D．will be interviewed by Dr Finkelstein

2.If both men and women are asked to keep their hands in hot water while taking in some pleasant smells, ______.

A．women may stand the pain of the hot water longer

B．men may keep their hands in the hot water longer

C．they will probably take their hands out at the same time

D．we are not quite sure who will take their hands out earlier

3.From the passage we learn that _________.

A．the reason why women are sensitive to smells is clear

B．the experiment for the sense of smell has come to an end

C．unpleasant smells affect men’s senses more than women’s

D．scientists have not totally explained the result of the study

4.Now scientists believe that _______.

A．mothers recognize their children only by sight

B．men’s sense of smell developed a long time ago

C．strong smells have a great influence on people’s senses

D．smells are helpful for mothers to spot their children

5.The writer wrote the passage in order to ________.

A．supply some entertainment to us

B．show women’s sharper senses than men’s

C．inform the readers of some knowledge

D．call for volunteers for the experiment
