高三英语单项填空中等难度题查看答案及解析

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

63. Which of the following is true according to the passage?

A. The electrical charge plants carry may shock or frighten us.

B. A tree will signal when it has been cut down.

C. Sauvin could make his plants send out signals some distance away.

D. Plants have feelings because they can receive signals without moving.

高三英语单项填空简单题查看答案及解析

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
