Because plants cannot move or talk, it is believed that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
60. Why was Backster surprised at the results of his studies?
A. Because he found someone had just cut down a tree.
B. Because he destroyed a plant by pulling it out of its pot.
C. Because he found that plants could move and speak after all.
D. Because he found that plants could express feelings of shock.
61. The plants sent out signals _____.
A. only when Backster Started to destroy plants
B. when Backster destroyed plants or other living things
C. only when he destroyed things such as insects
D. only when Backster placed the galvanometer on the leaves of the plants
62. The scientist called Sauvin _____.
A. did not agree with Backster’s ideas
B. did not get the same sort of results as Backster did
C. found out some of the same things that Backster did
D. got different results from Backster’s

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back.. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach..
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.
1.The holly plant has more spines on the lower leaves because most animals________.
A. are not tall enough B. like the lower leaves only
C. are not clever enough D. can get the lower leaves easily
2.To defend themselves, oak trees use________.
A. chemical means B. physical means
C. bitter chemicals D. sandy materials
3.How does tobacco protect itself against an attack from a caterpillar?
A. Its leaves fight against the attack by physical means.
B. Its roots send a messenger to discourage the caterpillar.
C. Its roots increase the production of nicotine when it is attacked.
D. Its leaves produce poisonous sand to drive the caterpillar away.
4.What would be the best title for this passage?
A. Plants and Animals B. How Plants Defend Themselves
C. Attacks and Defenses D. How Animals Eat Plant Leaves

One form of social prejudice(偏见)against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games,going on the Net and downloading MP3s are only for the youngsters. Isn't it unfair that older people enjoying a computer game should be frowned upon(反对)by their children and grandchildren?
Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has left more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain.
When personal computers were first introduced, most older people didn't believe they would ever familiarize themselves with them. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens,aged 72,says,"I find it very relaxing. It's not very demanding,but you still need to concentrate. "
Another development that has favored "grey games" is a change in the type of videogames available on the market. There's a greater variety of games to choose from,including more intellectual and complex strategy(策略)and simulation(模拟)games. Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real-world rail activities. Players can choose from a variety of challengers,such as keeping to a strict timetable and using helper engines during a winter storm.
Some people argue that "grey gamers" simply don't have the skills required for computer games, and that teenagers are better. This couldn't be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the "grey gamers" may well be far better than gamers half a century younger than them. In games where speed is the main consideration, older people would be at a disadvantage because they may have slower reaction time. On the other hand, "grey gamers" have a preference for slower-paced, mind challenging games.
1.The second paragraph is intended to _______.
A. show the best way to exercise the brain
B. stress the importance of good health
C. explain why grey gamers exist
D. teach how to play videogames
2.What was older people's attitude towards personal computers at first?
A. Doubtful. B. Concerned.
C. Enthusiastic. D. Supportive.
3.The method the author uses to develop Paragraph 4 is ________.
A. offering analyses B. giving examples
C. making comparisons D. providing details
4.The underlined part in Paragraph 5 probably means _______.
A. mind challenging games are not suitable for older people
B. teenagers should improve their skills with practice
C. playing computer games requires analytical thinking
D. older people may perform well in some computer games

高三英语阅读理解中等难度题查看答案及解析
A towering South American plant that is believed to kill animals with its spikes(尖刺) and use their rotting bodies as fertilizer is about to bloom(开花) in England. A rare Puya chilensis was planted at a greenhouse in Surrey, a county in the southeast of England about 15 years ago. However, despite its frightening description, the tall, spiked plant is considered a threatened species.
The Royal Horticultural Society has been feeding the plant a diet of liquid fertilizer. “In its natural habitat in the Andes it uses its razor sharp spikes to snare and trap sheep and other animals, which slowly starve to death and rot at the base of the plant, providing it with a bag of fertilizer,” reads a description on the RHS website, which adds that the plant gives off a “gruesome scent.”
But does the plant actually trap and eat sheep? Other sources have simply said it is “believed” that the plant traps small animals with its spikes. After the animals die of starvation, the plant is "believed" to then use their rotting bodies as fertilizer to feed itself.
"I'm really pleased that we've finally persuaded our Puya chilensis into producing flower," horticulturalist Cara Smith said in a press release on the RHS site. Regardless of whether it actually traps sheep, the plant does have sharp spikes that can grow up to 12 feet high and 5 feet wide. However, it’s not all death and danger for this plant. Its flowery blooms reportedly provide nectar(花蜜) for bees and birds.
The Puya chilensis blooms annually in its native land of Chile, but this is the first time it has done so after more than a decade of cultivation efforts from the RHS. "We keep it well fed with liquid fertilizer as feeding it on its natural diet might prove a bit problematic,” Smith said. "It's growing in the dry section of our glasshouse with its deadly spines well out of reach of both children and sheep alike."
1.From the passage we learn that in England the Puya chilensis _____.
A. feeds on man-made liquid fertilizer
B. often kills sheep and other animals
C. has once bloomed 15 years before
D. uses animals' rotting bodies as fertilizer
2.The underlined word “snare” in the second paragraph probably means“_________”.
A. catch B. stop C. fight D. kill
3.We can infer from the passage that _____.
A. it's dangerous to feed the plant
B. it's certain that the plant kills sheep
C. it's difficult for the plant to bloom in England
D. it's rare for the plant to bloom in South American
4.What does the writer mainly tell us?
A. A new plant is discovered in Chile.
B. How a rare plant is fed in England.
C. A rare plant is going to bloom in England.
D. How a plant traps animals in South America.

It’s generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.
It’s undeniable that behavior comes from our inner dispositions(性情), but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.
Moreover, we don’t just use our behavior to learn about our particular types of character --- we infer characters that weren’t there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn’t. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.
Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance(符合)with their true desires. Therefore, we should all bear in mind Kurt Vonnegut’s advice: “We are what we pretend to be, so we must be careful about what we pretend to be.”
1.According to the passage, personalities and attitudes are commonly believed to _______.
A. determine one’s behavior B. reflect one’s taste
C. influence one’s surroundings D. result from one’s habits
2.Which of the following would Daryl Bern most probably agree with?
A. The return of a wallet can indicate one’s honesty.
B. A kind person will offer his seat to the old.
C. One recycles plastics to protect the environment.
D. One buys latte out of love of coffee.
3.What can be inferred from the underlined sentence in the passage?
A. We fail to realize our inner dispositions.
B. We can be influenced by outside pressures.
C. Our behavior is the result of our true desires.
D. Our characters can shape our social relationships.
4.What does the author mainly discusses in the passage?
A. Personalities and attitudes. B. Preferences and habits.
C. Behavior and personalities. D. Attitudes and preferences.
