For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牵牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants，” they added.Tomatoes and potatoes kill insects to ________.
| A．get more sticky hairs |
| B．make themselves grow better |
| C．make their roots stronger |
| D．avoid falling down to the ground |
The word “carnivorous” in Paragraph 3 most probably means ________.
| A．fastgrowing | B．harmless |

| A．evolution of species |
| B．helps from other garden plants |
| C．artificial cultivation |
| D．nutrients preserved in rich soil |
The text is probably taken from ________.
| A．a student book | B．a science fiction |

Several years ago，a television reporter was talking to three of the most important people in America. One was a very rich banker， another owned one of the largest companies in the world， and the third owned many buildings in the center of New York.
The reporter was talking to them about being important.
“How do we know if someone is really important？” the reporter asked the banker.
The banker thought for a few moments and then said， “I think anybody who is invited to the Whiter House to meet the President of the United States is really important.”
The reporter then turned to the owner of the very large company. “Do you agree with that？” she asked.
The man shook his head， “No. I think the President invites a lot of people to the White House. You’d be important only if while you were visiting the President， there was a telephone call from the president of another country， and the President of the US said he was too busy to answer it.”
The reporter turned to the third man. “Do you think so？”
“No， I don‘t，” he said. “I don’t think that makes the visitor important. That makes the President important.”
“Then what would make the visitor important？” the reporter and the other two men asked.
“Oh， I think if the visitor to the White House was talking to the President and the phone rang， and the President picked up the receiver， listened and then said， ‘It’s for you.‘ ”This story happened in _______.

Stephen Hawking was born in Oxford, England, on January 8, 1942. At the age of 17, he entered University College, Oxford. He wanted to study mathematics, but took up the study of physics when math was unavailable. He received a Ph.D. in physics despite being diagnosed (诊断) with Ameliotrophic Lateral Sclerosis (肌萎缩性脊髓侧索硬化症) while at Oxford in 1963. In 1985 he became ill with pneumonia (肺炎), and since then has required 24-hour nursing. Dr. Hawking’s determination, along with the help of his family and associates, has allowed him to continue to work. In 1970 he began studying black holes. His research led him to predict that black holes send out radiation in the X-ray to gamma-ray(伽马射线) range of the spectrum (光谱). In the 1980s he returned to an earlier interest, the origins of the universe. He has co-authored many publications, such as 300 Years of Gravity and The Large Scale Structure of Space time. Dr. Hawking has also written books such as A Brief History of Time, Black Holes and Baby Universes and other Essays, The Universe in a Nutshell and others. He continues to give lectures, despite having been unable to speak since 1985, with the aid of a speech synthesizer (合成器) and a portable computer. He currently holds Isaac Newton’s chair as the Lucasian Professor of Mathematics at Cambridge University in England.Hawking went to University College, Oxford, in order to _____.

Americans like to travel on their yearly holiday. Today, more and more travelers in the United States are spending nights at small houses or inns(客栈)instead of hotels. They get a room for the night and the breakfast the next morning.
