Now discuss why Darwin did not publish his Theory of Evolution until 1859, about twenty years after his discovery. Do further research if necessary.
1 Why were many people "shocked" by Darwin's theory
2 What kind of person was Darwin according to the passage
3 How do you think the human species will evolve in the future
4 What have you learnt about the spirit of scientific exploration How can this spirit help you in your life and studies
句型梳理
1. (教材P. 67 ) After Darwin had spent some time in South America, his room on the ship was crowded with samples of the plants and animals he had collected.
本句是主复合句。afer引导的时间状语从句中使用了过去完成时 had spent，表示动作发生在主谓语 was crowded with表示的动作之前; he had collected 是省略了关系代 that/which 的定语从句对先行 the plants and animals 加以修饰和限制，因关系代词在定语从句中作宾语，故可省略。
2. (教材P. 68 )
Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before.
本句是主从复合句。that引导的宾语从句作 suspected 的宾语，其中使用了过去完成时 had evolved，表示动作发生在suspected之前，为过去的过去；宾语从句中 which had arived on the islands...是 which引导的非限制性定语从句，对ancestor进行补充说明。
