Every hour spent in watching TV, DVDs and videos as an adult reduces lifespan by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research shows that a sedentary（久坐的） lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The researchers set out to calculate the overall risk to lifespan from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be connected with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."We can learn from the passage that .
| A．whether you watch TV or not has nothing to do with how long you will live |
| B．if an adult watches TV for six hours every day, he will probably die five years earlier |
| C．physical inactivity and obesity won't shorten your life |
| D．a sedentary lifestyle offers huge benefits. |
The passage implies that _______.
| A．The longer one watches TV every day, the shorter he lives. |
| B．The conclusion of the study is unbelievable because it's based on Australian data. |
| C．Watching TV does greater harm to health than smoking and obesity |
| D．Watching TV harms children as much as adults. |
What do we know from the last three paragraphs?
| A．People in the United Kingdom watch TV longer than those in the United States. |
| B．That a sedentary lifestyle carries additional risks isn't supported by other studies. |
| C．Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%. |
| D．Australian data is much different from that of other countries. |
The passage is intended to _______.
| A．inform the readers of a research on watching TV |
| B．tell the readers large amounts of people often watch TV |
| C．tell the readers watching TV is also a good way to relax |
| D．warn the readers of the harm of watching TV and hope that they do sports |

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country, keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first- class roads, and other support facilities（配套设施）needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists , jobs and money are lost.
Which of the following do you think has been discussed in the part before this selection？
| A．It is extremely important to develop tourism. |
| B．Building roads and hotels is essential. |
| C．Support facilities are highly necessary. |
| D．Planning is of great importance to tourism. |
The underlined word“ inhabitants” （in Paragraph 1 ） probably means________.
| A．tourists | B．passengers |
| C．population | D．citizens |
Too much tourism can cause all these problems EXCEPT ________ .
| A．a bad effect on other industries |
| B．a change of tourists’ customs |
| C．over - crowdedness of places of interest |
| D．pressure on traffic |
It can be inferred from the text that ________ .
| A．the author doesn’t like tourism developing so fast |
| B．local people will benefit from tourist attraction |
| C．other parts of a country’s economy won’t benefit from tourism much |
| D．we can't build too many support facilities |
Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“ snow light”.
The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow -covered country. Rather ,a man’s eyes frequently find nothing to focus on （聚集）in a broad space of snow- covered without- grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid （流体） which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow - covered landscape. Even the scouts themselves throw lightweight, dark - colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow -blanketed landscape. By focusing their attention on one object at a time. the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.
| A．depends on whether the snow is white enough |
| B．makes no difference |
| C．makes much difference |
| D．depends on whether the snow is thick |
When the eyes are tired, tears flow out ________.
| A．to clear the vision |
| B．to make the eyes stop searching |
| C．to make the vision unclear |
| D．to produce more and more liquid |
Snowblindness can be avoided ________.
| A．by moving one’s gaze back and forth |
| B．by walking ahead and keeping looking around |
| C．by making up for the discomfort of one’s eyes |
| D．by providing the eyes with something to focus on |
The dream of flying into outer space, cherished by the Chinese people for centuries, will soon come true.
China launched its fourth unmanned spacecraft （飞船）“Shenzhou Ⅳ” on December 30 at the Jiuquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive（连续的）and successful launch of China - made rockets since October 1996. This launch has made it more realistic for China to send a person into space on its own following Russia and the USA.
Qi Faren，leading designer of the spacecraft system, said all the functions （功能） designed for manned flights have withstood （经受住）the test of three previous, successful launches and return landings of the “Shenzhou” spaceships.
China launched the “Shenzhou Ⅰ ”, “Shenzhou Ⅱ ”and “Shenzhou Ⅲ ”spacecrafts in 1999,2001 and 2002 respectively.
“Shouzhou Ⅳ” was to make it a more comfortable place in which astronauts can live and work. All parts of the application system for manned flight are aboard the “Shenzhou Ⅳ”craft in all test flights.
China’s manned flight programme began in 1992. A number of unmanned test flights will be launched before Chinese astronauts are sent into space.
Leading scientists in charge of China’s manned space programme said the successful launch of the “Shenzhou Ⅳ” laid a solid foundation for the country’s future task of sending Chinese astronauts to outer space.
The spacecraft returned to the earth on January 5, after completing seven experiments in space.
Officials at the centre said that“ Shenzhou Ⅴ”, a manned spacecraft, is expected to be launched later this year.
How many countries can send a person into space on its own by now？
| A．2. | B．3. |
| C．4. | D．Not mentioned. |
China’s manned flight programme began in ________.
| A．1992 | B．October 1996. |
| C．1999 | D．January 2003 |
As a matter of fact, ________ .
| A．“Shenzhou Ⅴ ”has been launched |
| B．“Shenzhou Ⅳ” was a manned spacecraft |
| C．“Shenzhou Ⅲ ”and“ Shenzhou Ⅳ” were not launched in the same year |
| D．the dream of man flying into outer space has come true in China |
Which is the most suitable title for the passage?
| A．The Successful Launching of “Shenzhou Ⅳ ”. |
| B．The Landing of “Shenzhou Ⅳ ”. |
| C．Chin a’s Manned Flight Programme. |
| D．The Third Country Sending a Person into Outer Space. |
Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since they, the plants, are the only form of life that is able to get and store energy.
The first plants to exist out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（进化）took place quickly. By the end of 100 million years, plants had developed their roots（根）,and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.
The main idea of the first paragraph is ________.
| A．life on land probably began 430 years ago |
| B．the first animal on land came from oceans |
| C．there wouldn't be animals without plants |
| D．plants are the only form of life that is able to get and store energy |
Which of the following statements is true according to the passage?
| A．Algae has existed for more than 430 million years. |
| B．It is impossible that algae might be the earliest plant on land. |
| C．Plants get food from animals in the oceans. |
| D．Evolution began after animals appeared on land. |
Plants with roots appeared about ________ million years ago.
| A．430 | B．300 | C．330 | D．100 |
According to the passage, ________ appeared earlier than ________.
| A．apples; oranges | B．oranges; apples |
