　　Albert Einstein (1879～1955) was one of the greatest and most original scientific thinkers of all time.

　　Born of Jewish parents at Ulm in Germany, he completed his education in Switzerland and got his Ph. D at the University of Zurich. He went to live in the United States in 1933 because of the rise of Nazism（纳粹）in Germany and Hitler’s persecution（迫害）of the Jews.

　　In 1905, while still at Zurich, he published his Special Theory of Relativity, which was based on things everyone may have noticed. If two trains are standing alongside each other and one train starts to move, a person sitting in the train may wonder whether his own train is moving or the other is moving, and before he finds out what is happening, he can see that one train is moving relatively to the other. From this and also from other more complicated facts, Einstein came to the conclusion that all motion is relative and that there are really no such things as absolute（绝对）motion. Some of the other conclusions he drew are that nothing can go faster than light, and that if something such as a ruler was moving faster and faster it would seem to get shorter and shorter as its speed was near the speed of light. By 1915, Einstein had made known his General Theory of Relativity. He also improved on Newton’s theory of gravity. Most of his theories have been tested and found to be true though some may sound strange. For his important work he was awarded the 1921 Nobel Prize for Physics.

(1) In 1933, Einstein wanted to live in the United States because ________.

A．he loved the USA．more than his own country

B．he had got some friends there with whom he could work together

C．he wanted to live quietly in the USA

D．he could no longer work in Germany when Hitler came into power

(2) Einstein published his Special Theory of Relativity when he was ________.

A．in the United States

B．in Ulm, Germany after he got his Ph．D

C．still in Switzerland at the age of twenty-six

D．still at the University of Zurich at the age of thirty-six

(3) One of the conclusions drawn by Einstein is that ________.

A．places go faster than trains and buses

B．people couldn’t run as fast as vehicles

C．light gobs the fastest of all the things

D．two trains can go in different directions

(4) Einstein added that if something such as a ruler was moving it would seem to get shorter and shorter ________.

A．because the ruler itself was short

B．when it was moving faster and faster

C．because we can’t see it clearly

D．because the ruler was broken into pieces

Another small animal that tigers eat in Ranthambhore （a wildlife park in northern India） is the porcupine （豪猪）．These animals are spread widely across India in open areas and grasslands; they often live in the earth and between rocks．They are good diggers, and in Ranthambhore are nocturnal （夜出的）; they only come out at night．They weigh 12 to 16 kilograms and reach the length of 80 to 90 centimetres．They live usually on vegetables and fruit and seem to have a good sense of smell．Porcupines defend themselves when attacked by moving backwards with their quills upright, often making a strange noise．
Several times, I have found the remains of quills where a tiger has killed and eaten a porcupine, but I have never actually seen the kill．In spite of the quills, experienced tigers will try to kill clearly by biting the porcupine’s head, its weakest spot．But the quills are very sharp and can give painful injuries to young tigers．If the quills have gone in very deeply or if they are stuck in the tiger’s paw, it will try to pull them out．Often, it will be successful, and the wound will get better．But, if the quills have gone in very deeply or if they are stuck in the tiger’s neck or mouth, where they cannot be reached, the wound will often turn bad．If this happens, the tiger is in pain and is less able to hunt animals．It has to look for easier prey and so may turn to cows on the edges of the forest．From this, it is a small step to becoming a man-eater．

【小题2】 The word “quill” here means ____．

A．teeth of a porcupine

B．feathers on a porcupine

C．long, sharp needle-like parts on a porcupine

D．paws of a porcupine

【小题3】According to this passage, what causes a tiger to become a man-eater?

A．When there are no porcupine for a tiger to catch．

B．When it turns to cows on the edges of the forest．

C．When a tiger wasn’t hurt seriously．

D．When it is difficult for a tiger to catch other animals．

【小题4】What is the proper title for this passage?

A．A Tiger and Its Food.

B．How Do Tiger Kill Porcupines?

C．What Can Cause a Tiger to Become a Man-eater?

D．A Porcupine.

The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes (趾) when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight.

Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree.
