Four decades ago a group of college students visited the mountains of Borneo to examine moth (蛾) populations. Now a team of British scientists, including a member of the original trip, has returned to the same sites to repeat the survey. They have found that, due to rising temperatures, the insects now live 68 meters higher.
Global warming is forcing tropical (热带的) species uphill to escape the rising temperatures at a rate of nearly 2 meters a year, the new study from Borneo suggests.
Since this was the only chance to repeat the original survey, the scientist did everything they could to do it exactly the same way, going at the same time of year, in July and August, using photographs to find the exact original sites of the moth traps.
"While this is the first study of insects, a few other studies of tropical species are starting to appear," said Thomas. "If you look across all those studies, you’ll find the same results, and it’s extremely difficult to think of any other explanation for them."
While some species might survive by finding places on the mountains with temperatures similar to those of their original habitats, others may run out of habitat on the rocky peaks, warns the study.
In a paper in the journal Naturein 2004, Thomas and 13 other experts analyzed the habitats of 1,100 species on five continents, and estimated that on average one quarter were at risk of extinction.
Last year a paper published in the Public Library of Science in the US warned that the risk of extinction in the tropics was becoming more and more serious. The authors, Jana and Steven Vamosi, estimated that 20-45% of tropical species were at risk of extinction.
1.If the temperature continues to rise at the same rate for ten years, the insects will live about ______.
A.6.8 meters higher B.19 meters higher
C.34 meters higher D.68 meters higher
2.What’s the problem for some species moving up mountains?
A.There’ll be too little space.
B.The temperature will be much too low.
C.They will be at greater risk of extinction.
D.They’ll find it hard to adapt to the environment.
3.We can learn from the passage that ______.
A.this survey of moths has been carried out many times
B.some scientists have put forward other explanations for the results
C.scientists tried to repeat the original survey
D.20-45% of tropical species were estimated to be at risk of extinction in 2004
4.Which of the following has been mainly discussed in the passage?
A.Climate change forcing moths higher.
B.Protecting moths from extinction.
C.How to research tropical moths.
D.How to study moths living on mountains.

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 disease 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, 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. Seeing the wonder of the first tube baby growing
C. Helping couples with infertility to have tube babies.
D. Challenging a disease which stops human having a baby.
2.What does the underlined word “afflicting”(Paragraph 4)most probably refer to?
A. Troubling B. Developing
C. Improving D. Confusing
3.Why did Professor Edwards begin his research on tube baby?
A. Because he thought it of great significance to have a child in life.
B. Because the birthrate around the world was unexpectedly low then.
C. Because a special child did make a difference to an ordinary family.
D. Because his fellow scientist wanted to give hope to the unlucky couples.
4.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’ achievement.
C. some people envied Professor Edwards for his being awarded.
D. the prize was late because the finding was first considered immoral.
5.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
