More Australians are overweight or obese than ever before, and the number is steadily increasing. Around 64 percent of men and 47 percent of women are carrying too much body fat. This means that the chances of obesity-related disorders, such as coronary heart disease(冠心病) and diabetes(糖尿病), is also on the rise. The popularity of crash dieting has caused many misunderstandings about weight loss. Most of these misunderstandings cause unhealthy weight loss behaviors.
A recent research of deaths in the United States from their National Health Nutrition Examination Survey suggests that being overweight may not increase your risk of dying. This finding is contrary to the past research that they thought the numbers of premature death(早死) linked to weight in the year 2000. The findings were that underweight and seriously obese people have an increased chance of dying compared with normal weight people. Interestingly, however, being overweight is related to a slightly lower chance of dying for your age. The effect of obesity on death rate may have reduced over time, perhaps because of improvements in public health and medical care. The authors say that body weight may not be such an important risk factor for premature death and that fitness, while smoking and too much fat in your diet may be more important.
65. If a person carries much fat, he or she _______________ .
A.knows how to keep healthy better than those who don’t
B.should lose weight as soon as possible to keep healthy
C.will surely suffer from both coronary heart disease and diabetes
D.might suffer from some diseases related to obesity
66. The underlined phrase “is contrary to” in the second paragraph probably means ___________.
A. agrees with B. disagrees with
C. proves D. combines
67. According to the recent research of deaths in America, ______________ .
A.underweight people will live longer than those overweight people
B.dying at an early age is connected with overweight
C.being overweight doesn’t necessary lead to premature deaths
D.being overweight is healthier than normal people
68. We can infer from the text that _____________ .
A.the writer wants to persuade people not to lose weight
B.misunderstandings about weight loss are more serious than ever
C.much progress has been made in public medical condition
D.the cause of premature deaths is heavy smoking

The journey to the moon had been the first step toward future exploration(探险) in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is millions of miles away. Traveling to the planets will be man’s next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.
Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed(确认) nor ruled out. Russians have discovered that the surface of Venus(金星) is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠) and the pressure is nearly a hundred times greater than that of the Earth’s atmosphere.
Scientists believe man may find planets which have the same conditions as those we have on Earth , but man should realize Earth will be his only home for a long time and begin to love and care for it.
63. According to the passage, traveling to the planets will be ________.
A. much easier and even more interesting B. far more exciting and dangerous
C. man’s final aim D. man’s first step
64. Which of the following is Not true?
A. Mars is nearer to the earth than the moon.
B. The moon is much nearer to the earth than Mars.
C. Of all the planets, Mars is the nearest to the earth.
D. All the planets are much farther to the earth.
65. From the passage, we can guess_____.
A. there is life on Mars
B. there is no life on Mars
C. the atmosphere of Mars is not so dense as that of Venus
D. scientists will have little hope to find the answers
66. Man can live on under the conditions of _______.
A. much too hot surface B. the same pressure as we get on earth
C. normal atmosphere as we have on earth D. both B and C
One of the most famous buildings in the United States is Carnegie hall ,the home of classical and popular music concerts in New York. Carnegie Hall is known not just for its beauty and history, but also for its amazing sound .It has been said that the hall itself is an instrument. It takes the music and makes it larger than life.
Carnegie Hall is named after Andrew Carnegie, who paid for its construction .Construction of Carnegie Hall began in 1980 and the official opening night was on May 5,1891.
The hall was owned by the Carnegie family until 1924 when it was sold to Robert E. Simon。The building became very old and in 1960,the new owner made plans to destroy it and build an office block. Isaac Stern led a group of people who fought to save Carnegie Hall and finally ,the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.
In 1986,people realised that Carnegie Hall had never kept proper records of its history.
Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall "s concert history.
Carnegie Hall is actually made up of several different halls ,but the Main Hall, now called the Isaac Stern Auditorium, is the most famous. The hall itself can hold an audience of 2804 in five levels of seating .Visitors to the top level have to climb up 105 steps to get there!
Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall "s history .Question:" How do I get to Carnegie Hall?" Answer:" Practise ,practise, practise."
64..It can be inferred that people wanted to save Cargenie Hall mainly because______.
A.it made a lot of money
B.it was worth visiting
C.many important concerts were held in it.
D.it made some players become famous
65.How did Carnegie Hall recover its concert history?
A.Through newspaper reports B.Through old concert programmes
C.Through old photographs D.Through old jokes
66.Why is the Carnegie Hall joke funny?
A.Because you expect the answer to be directions but not advice
B.Because Carnegie Hall is a place where musicians practise a lot.
C.Because it is difficult to find your way to Carnegie Hall
D.Because you don"t expect the answer to repeat the same word three times.
67.Which of the following is TRUE according to the passage?
A.Historical events happened inside Carnegie Hall
B.The city of New York paid for Carnegie Hall to be built .
C.Carnegie Hall was finally fixed up in 2000.
D.Isaac Stern saved Carnegie Hall ,so the Main Hall is named after him.
“Don’t just stand there,” goes a typical bit of American advice, “do something!” This expression is normally used in a crisis situation, yet, in a sense, it describes most Americans’ entire waking life, where action—any action—is seen to be superior to inaction.
Americans routinely plan and schedule an extremely active day. Any relaxation must be limited in time, preplanned, and aimed at “recreating” their ability to work harder and more productively once the recreation is over. Americans believe leisure activities should assume a relatively small portion of one’s total life. People think that it is “sinful(有罪的)” to “waste one’s time”, “to sit around doing nothing”, or just to “daydream”.
Such a “no nonsense” attitude toward life has created many people who have come to be known as “workaholics”, or people who are addicted to their work, who think constantly about their jobs and who are frustrated if they are kept away from them, even during their evening hours and weekends.
The workaholic syndrome(综合症), in turn, causes Americans to identify themselves wholly with their professions. The first question one American will ask another American when meeting for the first time is related to his or her work: ”Where do you work?” or “Who(what company) are you with?” And when such a person finally goes on vacation, even the vacation will be carefully planned, very busy and active.
America may be one of the few countries in the world where it seems reasonable to speak about the “dignity(尊严) of human labor”, meaning by that, hard, physical labor. In America, even corporation presidents will engage in physical labor from time to time and gain, rather than lose, respect from others for such action.
64.What is mainly talked about in the passage?
A.How Americans act during a crisis situation.
B.The workaholic syndrome in America.
C.Americans’ attitude towards relaxation.
D.Americans’ “no nonsense” attitude toward life.
65.Americans hold the belief that _______.
A.they should try to enjoy life as much as possible
B.they should go all out to help others in a crisis situation
C.they should not spend too much on relaxation
D.leisure activities should be an important part of their life
66.In America, corporation presidents will _______.
A.give instructions to workers only
B.often take part in physical labor themselves
C.look down upon the laborers
D.do physical labor only when it is necessary
67.When workers see their boss doing physical labor, they’ll _______.
A.take the place of him
B.stand by and watch
C.be more respectful to him
D.laugh at him
World food prices have dropped since early 2008. Prices of major crops have decreased by more than half from their height earlier last year. But they remain high compared to earlier years.
But FAO official Hafez Ghanem says lower prices have failed to end the food crisis (危机) in many poor countries. “For millions in developing countries,” he says, “getting enough food every day to live an active and healthy life is a distant dream. ”
The FAO says food shortage is a threat to people"s health. Today, two-thirds of the world"s undernourished people live in just a few countries. These are India, the Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan, Ethiopia and so on.
A report on food insecurity warns that the current economic crisis could send even more people into hunger and poverty.
In sub-Saharan Africa, the percentage of the people who continually go hungry fell from 34% in 1997 to 30% in 2008. But the FAO says Ghana is the only country that has reached two sets of hunger reduction targets. These were set by the 1996 World Food Summit and the Millennium Development Goals. The main reason is the growth in agricultural production in Ghana.
The FAO says some countries in Southeast Asia like Thailand and Vietnam have made progress in hunger reduction goals. But South Asia and Central Asia haven"t, and North Korea is still in hot water.小题1:What FAO official Hafez Ghanem says implies（暗示）__________
| A．it"s easy but takes long to provide people with enough food |
| B．enough food can make people more active and healthier |
| C．there is difficulty solving the food shortage in a short time |
| D．people in developing countries will never get enough food |
| A．hungry and unhappy | B．unhealthy for lack of food |
| C．not fat because of poverty | D．undeveloped and poor |
| A．The food production of the world |
| B．The hunger reduction target of the FAO |
| C．The food shortage around the world |
| D．The solution to the global food shortage |
Portable electronics that can be carried about easily are only as good as their batteries (电池) and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go.
The engine---about the size of a ten-cent coin---starts with a combustion chamber (燃烧室) that burns hydrogen. Its tiny parts are etched (蚀刻) onto silicon wafers (硅片) in the same manner that computer parts are etched onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.
But the devil in all this nice detail is efficiency. Tiny engine parts don’t always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.
The scientists’ goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t likely until at least the end of the next ten years.
小题1:According to the passage, the title suggests that _______ .
| A．batteries should be greatly improved |
| B．petrol will be used instead of batteries |
| C．the time of batteries will be gone forever |
| D．pollution problems caused by batteries must be solved |
| A．Problem | B．Advantage | C．Invention | D．Technique |
| A．The new invention doesn’t need any fuel. |
| B．The new engine has been produced in large quantities. |
| C．The new invention is much cheaper than the battery. |
| D．The new engine needs to be improved before it’s on sale. |
