            • 2． The famous scientist and thinker, Charles Darwin, was born on February 12, 1809. His family lived not far from the River Severn, England. Charles’ father was a well-known doctor and the son of a still greater doctor and scientist. Charles’ father hoped that his son would also become a doctor.  
                 As a boy Charles liked to go for walks in the fields and forests. He watched nature and compared what he saw with everything he had read in science books. He also liked collecting very much. He collected many things: eggs, stones, and leaves. His father did not like this, as Charles was not studying very well at school. ①为了成为一名医生,十六岁时达尔文就被送到爱丁堡大学(Edinburgh University)学习。But he was interested in the history of nature. Then he studied at Cambridge University until 1831. 
                 Some time later, he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His professor advised him to go. He said the trip would be just for Darwin. So when the ship left England in December 1831, Darwin was on it. The research lasted almost five years. The Beagle studied the waters in the sea near South America. It also visited New Zealand, Australia and islands in the Pacific. Darwin saw many new plants and animals. He collected all kinds of plants, which he sent home from the places he visited. When he returned home, Darwin was warmly greeted by his families and many friends. In 1842, Darwin went to live in Kent, where he continued his studies of the changes in nature. ②Darwin understood that plants and animals are not always the same, and that they really change. 
                 By 1859, Darwin had finished his famous book The Origin of Species. It made a great hit in the world of science. ③He was opposed(反对)by the church and even by some scientists. But later, more and more scientists agreed with him. Darwin continued his studies in science until he died in 1882.

            • 3．

              You can see kangaroos everywhere in Australia．They appear on TV, in books and, in the shops．The government even plans to put them on passports．[103]Although it's the best loved animal in Australia, millions of kangaroos are killed every year．Why, people ask, do the Australians kill them? Quite simple, there are too many of them．

              The number of kangaroos in Australia is believed to be 20—25 million．It is larger than the number of people living in the country．

              There are several reasons for the growth in the number of kangaroos．There is plenty of water in the places where kangaroos live and many of the dingoes (澳洲野狗) that like to kill and eat kangaroos are not there anymore．

              Kangaroos also produce (产生) the young all the year round．When a female (雌的) kangaroo gives birth , she then gets pregnant (怀孕) again immediately．The large number of kangaroos means some kangaroos don't get food to eat．They are so hungry that they break into farms and fight against other animals for food．

              [104]To solve the problem, the Australian government allows a certain number of kangaroos to be killed each year．

              Many people don't think that it's right to kill kangaroos but the government thinks that it is only to help the farmers．Australia sells 5 million kilos of kangaroo meat every year—it is used to make hamburgers for dogs．
