It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野).
For Killing Wolves
In Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life．When the deer can’t find enough food，they die.
If the wolves continue to kill large numbers of deer, their prey(猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We’d also save some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population．
Against Killing Wolves
If you had lived long ago，you would have heard many different stories about the dangerous wolf．According to most stories，hungry wolves often kill people for food．Even today，the stories of the “big bad wolf” will not disappear．
But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell．When wolves eat other animals，they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.
Although some people say it is good sense to kill wolves，we say it is nonsense! Researchers have found wolves and their prey living in balance．The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.
The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can’t always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The “big bad wolf” has arrived! And everyone knows what happens next.
1.According to the passage, some people in North America favor killing wolves for all the following reasons EXCET that ________.
A．there are too many wolves
B．they kill large numbers deer
C．they attack cows and chickens for food
D．they destroy the wilderness plant life
2.According to those against killing wolves, when wolves eat other animals, ________.
A．they never eat strong and healthy ones
B．they always go against the law of nature
C．they might help this kind of animals survive in nature
D．they disturb the ecological balance in the wilderness
3.The last sentence “And everyone knows what happens next” implies that in such cases ________.
A．farm animals will be in danger and have to be shipped away
B．wolves will kill people and people will in turn kill them
C．wolves wilI find enough food sources on famls
D．people will leave the areas where wolves can live
More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.
The prize for Dr. Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a £900,000 check. The Nobel Assembly described IVF as a “milestone in modern medicine”.
With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF — leading to the birth of the world’s first test tube baby. Dr. Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.
It was a scientific breakthrough that transformed the lives of millions of couples. They said: “His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10% of all couples worldwide.”
Louise Brown, the world’s first test tube baby, made international headlines when she was born in Oldham, Gtr Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.
Ivf-in-vitro fertilization is the process whereby egg cells are fertilized outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five—the same as healthy couples who conceive naturally.
Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955. He once said: “The most important thing in life is having a child. Nothing is more special than a child.” With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.
But his work attracted widespread criticism from some scientists and the Catholic Church who said it was “unethical and immoral”.
Martin Johnson, professor of reproductive sciences at the University of Cambridge, said the award was “long overdue”. He said: “We couldn’t understand why the Nobel has come so late but he is delighted — this is the cherry on the cake for him.”
Professor Edwards was too ill to give interviews but a statement released by his family said he was “thrilled and delighted”.
1.What is Robert Edwards’ contribution to science?
A. Enabling millions of couples to live a better life.
B. Helping couples with infertility to have tube babies.
C. Seeing the wonder of the first tube baby growing
D. Challenging a disease which stops human having a baby.
2.Why did Professor Edwards begin his research on tube baby?
A. Because a special child did make a difference to an ordinary family.
B. Because the birthrate around the world was unexpectedly low then.
C. Because he thought it of great significance to have a child in life.
D. Because his fellow scientist wanted to give hope to the unlucky couples.
3.It can be inferred from Paragraph 8 and Paragraph 9 that ________.
A. Professor Edwards deserved the prize for his breakthrough
B. different opinions were voiced on Professor Edwards’ finding
C. some people envied Professor Edwards for his being awarded
D. the prize was late because the finding was first considered immoral
4.What might be the best title for the passage?
A. Life Stories of Robert Edwards
B. Preparations for Having a Baby
C. Nobel Prize for IVF Expert Edwards
D. Treatment of Infertility in a Lab
Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners — the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog, and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly, the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person.
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs，but won’t get rid of the need for human workers.
1.The latest robot is more advanced than Groundhog, mainly because ________.
A. it can map abandoned mines
B. it has a real sense of logic
C. it can see in the dark tunnels
D. it’s smaller than Groundhog
2.The underlined phrase “throws a fit” in paragraph 4 probably means“________”.
A. gets sickB. gets angry
C. becomes hungryD. becomes cheerful
3.We can infer from the last paragraph that ________.
A. the mine robots will have a very bright future
B. robots in mines will serve much in the automotive industry
C. there will be no need for human workers in mines
D. robots in mines only do some simple jobs now
4.We can infer from the text that ________.
A. robots cannot do dangerous work in dark areas
B. the mining robots do most of the mining work at present
C. groundhog can discover the presence of dangerous gases
D. experts are trying to make robots help miners with dangerous work

The back-to-school season is upon us, and once again, parents across the country have loaded their kids’ backpacks up with snack packs and school supplies. It’s a good moment to reflect on what else we should be giving our kids as they head off to school.
American parents are feeling particularly anxious about that question this year. The educational process feels more than ever like a race, one that starts in pre-school and doesn’t end until your child is admitted to the perfect college. Most parents are more worried than they need to be about their children’s grades, test scores and IQ. And what we don’t think about enough is how to help our children build their character—how to help them develop skills like perseverance, optimism, responsibility, and self-control, which together do more to determine success than S.A.T. scores or I.Q.
There is growing evidence that our anxiety about our children’s school performance may actually be holding them back from learning some of these valuable skills. If you’re concerned only with a child’s G.P.A., then you will likely choose to minimize the challenges the child faces in school. With real challenge comes the risk of real failure. And in a competitive academic environment, the idea of failure can be very scary, to students and parents alike.
But experiencing failure is a critical part of building character. Recent research by a team of psychologists found that adults who had experienced little or no failure growing up were actually less happy and confident than those who had experienced a few significant setbacks in childhood. “Overcoming those obstacles,” the researchers assumed, “could teach effective coping skills, help engage social support networks, create a sense of mastery over past adversity, and foster beliefs in the ability to cope successfully in the future.”
By contrast, when we protect our children from every possible failure—when we call their teachers to get an extension on a paper; when we urge them to choose only those subjects they’re good at—we are denying them those same character-building experiences. As the psychologists Madeline Levine and Dan Kindlon have written, that can lead to difficulties in adolescence and young adulthood, when overprotected young people finally confront real problems on their own and don’t know how to overcome them.
In the classroom and outside of it, American parents need to encourage children to take chances, to challenge themselves, to risk failure. In the meantime, giving our kids room to fail may be one of the best ways we can help them succeed.
