Homework 1）Summarize what you have learned from Darwin's journey of discovery. 2）Read the extended reading material Extended reading（1） Charles Darwin was born in 1809 in England.At school he didn't do well and got poor marks.He was a good athlete though and loved studying nature.He also kept doing chemistry experiments. His father was a doctor and expected Charles to become one too.Charles started studying medicine at Edinburgh University but soon gave up his studies there. In 1831，Darwin went on a five­year journey to South America，Australia and South Africa by ship.He was seasick but the things he saw on this trip changed his life.He collected many animal and plant specimens. In 1839，Darwin married his cousin Emma Wedgwood with whom he had ten children! He was a loving father and enjoyed family life which was always more important to him than his research.In spite of having many health problems throughout his life，Darwin lived until he was 73. Darwin's most famous book On the Origin of Species came out in 1859 and sold out in a day.It said that all living things were related.His ideas were not popular at first，but now most people agree with them and admire Darwin as a great scientist. Extended reading (2) It's well known that Charles Darwin's famous theory of evolution annoyed many people because it was against the Biblical view of creation. But few know that it also created problems for Darwin at home with his deeply religious wife, Emma.      "Darwin held back the publication of On the Origin of Species to avoid offending (触怒) his wife," says Ruth Padel, the naturalist's great - great - granddaughter. "Emma told him that he seemed to be putting God further and further off", Padel says in her north London home. "But they talked it through, and Emma once said, 'Don't change any of your ideas for fear of hurting me.'"      As the world celebrates the 200th birthday of the man who changed scientific thought forever and the 150th anniversary of his book today, even his opponents admitted he was a giant figure.      Though opposition to his theory continues, it is the elegant explanation of how species evolves through natural selection that makes his 200th birthday such a major event.      More than 300 celebrations have been planned in Britain alone, where Darwin's face graces(使增光)the 10-pound bill along with that of Queen Elizabeth II.      Shrewsbury, the central England town where Darwin was born and raised, is holding a month-long festival for its most famous son. Down House, his former home near London, will hold a permanent exhibition recreating some of his most famous experiments.      Many more events have been planned all over the world.      What would he be doing if he were alive today? Padel thinks he would properly be studying DNA and the immune system. 学科网（北京）股份有限公司 $$
