I suddenly heard an elephant crying as though frightened. Looking down，I immediately recognized that something was wrong，and ran down to the edge of the near bank. There I saw Ma Shwe with her threemonthold calf struggling in the fast-rising water，and it was a lifeanddeath struggle. Her calf was floating(漂浮) and screaming with fear.Ma Shwe was as near to the far bank as she could get，holding her whole body against the rushing water，and keeping the calf pressed against her huge body.Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean over the mother's body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort，she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment，she fell back into the river. If she were carried down，it would be certain death. I knew，as well as she did，that there was one spot (地点) where she could get up the bank，but it was on the other side from where she had put her calf.
While I was wondering what I could do next，I heard the sound of a mother's love. Ma Shwe had crossed the river and got up the bank and was making her way back as fast as she could，roaring (吼叫) all the time，but to her calf it was music.The moment the author got down to the river bank he saw .

Most of the sandstorms that had swept China last year came from foreign land，a Chinese official in charge of desertification（荒漠化） control said on Monday. And the invasions(入侵)could partly explain the frequent sandstorms in the country in recent years despite its achievements in desertification control.
Since the start of last spring，the north and northwestern Chinese regions had been hit by 17 sandstorms，of which，a dozen came from foreign land.
Situated in the centralAsia sandstorm region，one of the world's four largest sandstorm sources，China also suffers from sandstorms from outside the country while being blamed as a sand source to northeast Asia. The other three major sources are in Africa，North America and Australia.
The land suffering from desertification has been decreasing by 7,585 square kilometres annually in China，and the area of sandy land has also been falling by 1,284 square kilometres a year.
The shrinkage(收缩)forms a clear contrast to the fact that the land suffering from desertification and sandy feature was added by 10,400 square kilometres and 3,436 square kilometres late last century，respectively.
Currently，the desertification land in China makes up 2.64 million square kilometres，accounting for 27.46 percent of the nation's land，and its sandy land totals 1.74 million square kilometres，accounting for 18.1 percent of the country's total.What does the underlined word “decreasing” mean in Paragraph 4?
| A．Going down. | B．Going up. |
| C．Coming from. | D．Taking up. |
Where do most of the sandstorms in China come from?
| A．The northwestern Chinese regions. |
| B．The northern Chinese regions. |
| C．The western part of China. |
| D．Foreign countries. |
Which of the following is believed to be the sand source to northeast Asia?
| A．Mongolia. | B．Africa. |
| C．China. | D．Australia. |
What can we infer from this passage?
| A．The land in China suffering from desertification has been increasing greatly. |
| B．China has made achievements in its own desertification control. |
| C．The desertification land makes up nearly half of China's territory. |
| D．Little progress has been made in controlling desertification in China. |

The is that countries around the world have growing mountains of because
People are throwing out more rubbish than ever before.
How did we a throwaway society ? First of all, it is now easier to an object than to spend time and money to repair it. modern manufacturing and technology, companies are able to produce products quickly and inexpensively. Products are plentiful and .
Another cause is our of disposable(一次性)products. As people we are always looking for to save time and make our lives easier. Companies thousands of different kinds of disposable products: paper plates, plastic cups, and cameras, to name a few.

On May 23,1989, Stefania Follini came out from a cave at Carlsbad , New Mexico．She hadn’t seen the sun for eighteen and a half weeks ．Stefania was in a research program, and the scientists in the program were studying body rhythms （节奏）。In this experiment Stefania had spent 130 days in a cave ,30 feet in depth．
During her time in the cave, Stefania had been completely alone except for two white mice．Her living place had been very comfortable ,but there had been nothing to feel her the time ．She’d had no clock or watches , no television or radio．There had been no natural light and the temperature had always been kept at 21℃
The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24hour day, she had stayed awake for 20～25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 171 bs in weight as a result!She had also become rather depressed (抑郁).
How had she spent her time in the cave?As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.
The experiment showed that our body clocks are affected by light and temperature. For example, the pattern of day and night makes us wake up and go to sleep. However, people are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10:00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!Stefania stayed in the cave for a long time because___________．
| A．she was asked to do research on mice |
| B．she wanted to experience loneliness |
| C．she was the subject of a study |
| D．she needed to record her life |
What is a cause for the change of Stefania’s body clock?
| A．Eating fewer hours |
| B．Having more hours of sleep |
| C．Lacking physical exercise． |
| D．Getting no natural light． |
Where does the text probably come from?
| A．A novel． | B．A news story． |
| C．A pet magazine． | D． A text |
Welcome to the future. It’s year 2050 and Scotland is now powered completely by“clean”energy.
Homes have entire roofs made of solar materials, rooms are kept warm by wallpaper, and people go to and from work in electric and hydrogen( 氢) cars.
Oil is still being found in the North Sea, but it’s not now only used to keep aircraft flying. And a new 500---mile underwater link with Iceland has been built to catch heat from the hot springs. There’s still a role for king coal—but the black diamonds are now environment---friendly.
People will be able to import the electricity they need and export any excess(超过的量) they make through rooftop windmills(风车). New technology will store electricity better and provide it on demand. Heat exchangers will provide heating and hot water.
Harmful carbon dioxide waste is being piped offshore to St Fergus and from there into some of the remaining oil—producing fields to be stored safely without entering the atmosphere. Gas remains the preferred energy source of industry and is now shipped in liquid form. But hydrogen is imported through pipelines from France and from a geothermal (地热的) plant in Iceland.
Hydrogen—fuelled cars have become popular. Electric bikes are common in cities using the new urban two—wheel network. Electric vehicles have become common, and their performances have been improved because of the developments in electrical drive technology like high—temperature super conducting motors. Many people leave their vehicles in a giant park where they can be recharged from the national electrical system . Oilseed rape (油菜) is widely grown to fuel some motors .What does the underlined phrase in paragraph 2 mean ?
| A．The hot springs | B．Oil |
| C．Coal | D．Oil and coal |
Which sources of energy play a more important role in people’s daily life in the future ?
| A．Oil and coal |
| B．Hydrogen and gas |
| C．Electricity and gas |
| D．Solar energy and wind |
The means of transport people use in 2050 do not include__________.
| A．windmills | B．electric bikes |
| C．hydrogen—fuelled cars | D．aircraft |
The passage is written to tell us in the future_____________.
| A．life will be better and better |
| B．the energy will become cleaner and cleaner |
| C．people will use some new sources of energy |
| D．people will pay more attention to the environment |
