 阅读理解  Charles Darwin was a naturalist who described his findings in many papers and published works. The basis of his works was the theory of evolution (进化). Darwin pieced together information from his earliest studies to continuously expand upon the heart of his theory called "natural selection".  The root of Darwin's theory can be traced back to his time at the University of Edinburgh. There he first became interested in invertebrates (无脊椎动物) and the possibility that other creatures evolved from simpler organisms like them. Then in Christ's College in Cambridge, Darwin began to collect knowledge about plants and the earth.  Though Darwin began his life as a somewhat religious person, several ideas like the argument that nature was a process of "God's design" did not seem to match his rapidly increasing understanding of nature and geology. When the chance to contribute to his study as a naturalist on the HMS Beagle presented itself, Darwin was excited to undertake that role. Though the voyage lasted five years and was extremely difficult and tiring, it provided the basis of knowledge that Darwin would build upon to write his description of natural selection.  Darwin's time aboard the HMS Beagle and his time spent off the ship in South America were full of observation and collection. Apart from the creatures, Darwin explored the rise and fall of the land and grasped the massive time span (时间跨度) of the earth and the changes it had experienced as an environment during its time span.  Upon his return, Darwin worked for years to produce the first edition of his theory of natural selection in his 1859 book On the Origin of Species.  Darwin drew his theory from years of studies of various creatures including some extinct animals. It was paired with knowledge of geology and how the earth had evolved as an environment in which every living thing has existed.  （1） When did Darwin's theory of evolution originate?  A . When he graduated from the University of Cambridge. B . When he studied at the University of Edinburgh. C . When he began his travel on the HMS Beagle. D . When he gained some knowledge of the earth. （2） Which of the following sayings can best describe Darwin's voyage?  A . Practice makes perfect. B . It's never too late to mend. C . Experience is the best teacher. D . He who risks nothing gains nothing. （3） What can we learn about On the Origin of Species from the text?  A . It is actually a record of Darwin's exploration in South America. B . It presented the theory of natural selection for the first time. C . It mainly focuses on the earth's role as an environment. D . It came out before Darwin's voyage. （4） What is this text mainly about?  A . Darwin's talent for studying creatures. B . The story of Darwin and the HMS Beagle. C . The birth of Darwin's theory of evolution. D . Darwin's excellent educational background. 答案： B C B C
