Each time a city building is set up, the grass in that spot and trees that once reached up to the sky are replaced by a tar (柏油) roof. In addition to that, roads, parking lots, and yet more buildings are being constructed. The total lost green space can have a very real effect on a city’s air temperature, air quality and energy costs. On a summer day in most American cities, a tar roof can feel like the inside of an oven. But what if we could replace the hot roof of each skyscraper or building in a city with grass or a garden?

    Whether it holds vegetable gardens, wildflowers, or meadow grasses, a green roof can lower the temperature above a building by 60 degrees, which can reduce the building’s energy costs. If used more widely, green roofs could decrease a city’s total energy costs, reduce polluted air from power plant , and improve air quality and public health. But that’s not all — green roofs are a great way to deal with water management in urban areas with overwhelmed sewerage (排污) systems, and actually extend the life time of the roof itself. And green roofs do something else: They beautify the city — whether you’re on the 3rd floor or the 30th. Now that’s a great achievement.

    The environmental nonprofit group Earth Pledge is promoting a Green Roofs progamme. To learn more about how to create a green roof — and the benefits it will provide — visit its website at EarthPledge.com.

Canadian scientists have found that the more emotional or mental challenges a person faces in a day, the less determined they become to work out physically.
However, the findings should not stop us from keeping fit. Experts believe that willpower (意志力)is like a muscle ， and needs to be exercised to help one avoid the temptation (诱惑)spending a night on the couch instead.
Kathleen Martin 一 Ginis, a professor of kinesiology 一 the science of movement 一 who led the study, says everyone has a limited amount of willpower, and that it will be reduced by stress. Miss Martin 一 Ginis, of Canada' s McMaster University, explains, "Cognitive (认知的)tasks, as well as tasks such as regulating (调整)one' s emotions, can reduce one' s capacity to force oneself to exercise."
Her team of scientists performed a so — called " Stroop" test on volunteers to reach their conclusions. The experiment involved showing participants words associated with colors but printed in different colors - for example ， the word " blue " written in red ink . ' Participants were divided into two groups. One group was asked to name the color of the ink ， instead to say the printed word ， while the other wasn't Martin ― Ginis says ， " After we used this cognitive task to use up their self 一 regulatory capacity, the participants didn't exercise as hard as those who had not performed the task. ，， The more people concentrated on the cognitive task ， the more likely they were to skip exer­cise sessions (活动时间)over the next eight week. You only have so much willpower .
However, there are ways to strengthen willpower. The study found the listening to music before going to the gym can help, as well as making a commitment to work out with friends. It also concluded that willpower can be stretched by constantly cake ， or forcing oneself to study an extra hour each night.
Martin - Ginis adds, "There are strategies people can use to help revitalize (使恢复活动) themselves after they’ve used up their self 一 regulation. Willpower is like a muscle ： it needs to be used to stay strong.
61.According to the experts, human willpower    .
A.can be exercised through muscle movement
B.can regulate itself to resist temptations
C.is weakened by stressful cognitive or emotional tasks
D.is reduced by lack of physical exercise.
62.We learn from Paragraph 4 that the experiment      .
A.made use of the Stroop test
B.asked one group of participants to name the words
C.required researchers to write the word "blue" in red ink to make it easily recognizable.
D.showed that those who hadn't performed the task were smarter than those who had
63.All the following are ways to strengthen one's willpower EXCEPT________
A.listening to music before doing exercise
B.promising to work out with friends
C.training oneself repeatedly to resist temptations
D.forcing oneself to do the same thing each day
64.Which of the following is in agreement with Miss Martin ― Ginis' idea?
A.Human's willpower is limited to a certain level
B.The cognitive tasks could make people ignore exercise
C.Challenging tasks could make people ignore exercise
D.Exercise is an important way to strengthen one's willpower.
65.What can we infer from the passage?

B.McMaster University is famous for its kinesiology.
C.Effective ways to resist temptations have been found.
D.the study has an impact on the science of movement.

Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

B. Its ability to pass on the virus frequently.
C. Its outbreaks in cities with large populations.
D. Its ability to defend itself and resist new drugs.
79. It can be inferred from the passage that _______.            .
A. no drugs have been found to treat the disease
B. the alternative treatment is not easily available to most people
C. malaria has developed its ability to resist parasites
D. nobody knows what will be the drug to treat the disease
80. Which of the following questions has NOT been discussed in the passage?

The ’80s’ “important role” in the family has also meant a greater concentration and focus on the individual. And, it has made the word “me” one of the most frequently used words. Everything seems to be about “me”. This generation has a greater awareness of itself.
Some people do not seem to agree that all this is self-centred. When Cai Fuchao, Beijing’s publicity head, was asked to comment on the lack of responsibility of university students during the SARS period, his reply was: “Modern university students are ambitious, knowledgeable and have a very strong sense of responsibility to the society.”
As news analyst from sina.com, Pan Fengliang, echoed（随声附和）that, saying that blindly blaming them(for running away during the SARS outbreak) was prejudiced and unfair and not backed with evidence.
No doubt, the development of information technology has contributed its bit to broadening, or bending, the minds of the 80s generation.
Some people even call Gen’80 “the E-generation”. They get in touch with each other via email, QQ, ICQ and MSN.
While the people of the ’60s and ’70s swarmed（涌往）to Shanghai to catch Luo Dayou, Gen’80s were on the BBS saying that it was “really dumb”.
“The internet is so much more to those of the ’80s than you can imagine,” said Wu Junyong, an IT engineer who was born in 1978.
In Wu’s opinion, it’s the Internet that separates the 70s from the 80s, “Many of the’70s don’t see why those from the ’80s can spend everyday in front of a computer.”
A new weekly Magazine/163.com survey last year found that 40 percent of the 7,000 people surveyed, born in the ’80s, thought the computer was the most important article in life; more than 70 percent of their parents preferred the home.
67. Which of the following statements is true according to the passage?
A.The development of information technology contributed to the ’80s’greater awareness of itself.
B.The E-generation rushed to Shanghai to catch Luo Dayou.
C.All the ’80s can spend every day in front of a computer.
D.Not all people think that the “born in the 1980s” are selfish and irresponsible.
68. What can we infer from the passage?
A. All the ’80s have a strong sense of responsibility to the society.
B.Computers play a more important part in the life of the ’80s, who perhaps can’t live without them.
C.The ’80s generation are ambitious, knowledgeable and responsible.
D.People can’t imagine why the ’80s like internet so much.
69. The best title for this passage could be ______.
A. The self-centred generation              B. The internet generation
C. The “born in the ’80s”generation         D. The life of the ’80s
70. The purpose of this passage is to tell us _______.
A.people’s different opinions towards the ’80s generation.
B.the ’80s are the E-generation.
C.the ’80s are different from others in society.
D. the’80s have their own characteristics and we shouldn’t lose confidence in them

After my husband died suddenly from a heart attack，my world crashed around me．My six children were all under 10，and I was burdened with the responsibilities of earning a living，and   caring for the children．I was fortunate to find a wonderful housekeeper to care for the children during the week，but from Friday nights to Monday mornings，the children and t were alone．
One Friday evening I came home from work to find a big pretty German shepherd off our doorstep．This dog seemed to intend to enter the house．The children liked “German” immediately and begged me to let him in．I agreed to let him sleep in the basement．That night I slept peacefully for the first time in many weeks．
The following morning we made phone calls and checked lost-and-found ads for German’s owner, but with no results．
On Sunday I had planned to take the children on a picnic．Since I thought it best to leave German behind in case his owner came by，we drove off without him．When we stopped to get gas, we were amazed to see German racing to the gas station after us．No way was he going to be left behind．
Monday morning I let him out for a run．He didn’t come back and we were all disappointed．
We were convinced that we would never see him again．We were wrong．The next Friday evening,
German was back on other doorstep．Again he stayed until Monday morning，when our housekeeper arrived．
This pattern repeated itself every．weekend for almost 10 months．We grew more and more fond of German．We took comfort in his strong，warm presence，and we felt safe with him near us．
As German became part of the family，he considered it his duty to check every bedroom to be sure each child was cozy in bed．
Each week，between German’s visits，I grew a little stronger，a little braver and mole able to cope；every weekend we were no long alone and enjoyed his company．Then one Monday morning we patted him on his head and let him out for what turned out to be the Iast time．We never saw German again．
