       A leading researcher into old age has warned that the dream of living forever, or at least much longer than at present, could turn into a curse（祸根）rather than a blessing. It may become possible to lengthen the    1    human life by controlling genes---but what we gain may not be worth the price we would have to pay.

       Professor John Grimley Evens believes that    2   , maximum life expectation is 115, but that with gene    3    it might be possible to extend this. The professor says, however, that a

4    lifestyle can extend the average lifespan of everyone at the moment.

       “We know a lot already about how people’s lifestyles    5    their lifespan. There is increasing    6    to suggest that sensible lifestyles are effective in later life as well as in early and middle life.”

       “It is never too late to gain some    7    from giving up smoking, from drinking less alcohol, from taking up sensible patterns of diet and exercise and from controlling body weight. We already know how to     8    human life.”

       The professor believes that the process of lengthening life by means of gene therapy might bring dangers with it. If gene therapy affected only one part of the human body but not all of it, people might be    9    capable of living longer, but would start to be worse mentally at a much earlier age.

     Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.

     The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”

     The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.

     Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower  temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.

     The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.

The underlined word “scenario” in Paragraph 2 probably means         .

A. imagination        B. intention        C. expectation       D. prediction

From the passage, we can infer that         .

A. corals have no difficulty in ad高☆考♂资♀源?网apting the temperature change

B. if we take quick actions we can avoid the destruction of corals

C. we can find corals in many areas of the seas or oceans

D. the algae help corals to live

Which of the following is NOT the cause of the destruction of coral on the Great Barrier Reef?

A. Direct sunshine.              B. Over-fishing.

C. Global warming.              D. Pollution.

By saying “Coral has a narrow comfort zone” (Para. 3), the author means         .

A. coral can only live in a small area     

B. coral prefers a crowded place

　　Happy birthday! Do birthdays really make people happy? Of course they do. Birthdays celebrate the day we were born. What's more, that extra candle on the cake represents another year of growth and maturity (成熟)—or so we hope. We all like to imagine that we're getting wiser and not just alder. Most of us enjoy observing the miracle of growth in others as well. For instance, seeing our children develop and learn new things makes us feel proud. For Americans, like people in most cultures, growing up is a wonderful process. But growing old? That's a different story. Growing old is not exactly pleasant for people in youth-oriented American . Most Americans like to look young, act young and feel young. As the old saying goes, “You're as young as you feel . ” Older people joke about how many years young they are ,rather than how many years old. People in sane countries value the aged as a source of experience and wisdom. But Americana seem to favor those that are young, or at least “young at heart”. Many older Americans find the“golden years” to be anything but golden. Economically, “senior citizens”often struggle just to get by. Retirement — typically at age 65—brings a sharp decrease in personal income. Social Security Benefits usually cannot make up the difference. Older people may suffer from poor nutrition(营养) , medical care and housing. Some even experience age discrimination.

　　Ironically, the elderly population in America is expanding fast. Why? People are living longer. Fewer babies ere being born. The middle-aged “baby boomers” are rapidly entering the ranks of the elderly, so America may soon be a place where wrinkles(皱纹) are “in” . Marketing experts are already focusing on this growing group of consumers. And even now the elderly have a great deal of political power.

　　A common stereotype(模式化的形象) of older Americana is that they are usually “put away” in nursing homes and forgotten about. Actually, only about 5 percent live on acme type of institution(慈善机构).

　　More than half of those 65 or older live with or near at least one of their children. The vast majority ad the elderly live alone and take care of themselves.

　　In spite of challenges they face, Americans in their “twilight years (暮年)” generally refuse to we up on life. They find a variety of ways to keep themselves active. To help them stay in shape, they may join mall (商业区) walkers club, fitness programs and even the “Senior Olympics” .They can enjoy hours of entertainment at senior centers and adult amusement parks. Many enroll in continuing education programs to maintain their mental skills. For Americans, if you're going to grow old, you might as well do it gracefully.

Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的) than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter” while men have more of latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎儿) are about mine weeks old, which can be seen in the action of children ad young as one. A boy would try to climb a barrier (障碍物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.
