第一个句子是manhattan里第七章出现的:
1、She will pay you when you have taken out the garbage.
manhattan给出的解释是when在这里理解为after,然后给出了一个解释的句子:She will pay you clearly after you take out the garbage and have proven it!
我还是没能弄懂为什么will和现在完成时可以放在一起,现在完成时不是应该用来表示过去发生持续到现在,或者影响持续到现在的事件吗?
第二个句子是OG13里P41的40题,正确的句子是:In 1995 Richard Stallman,a well-known critic of the patent system,testified in Patent Office hearings that,to test the system,a colleague of his had managed to win a patent for one of Kirchhoff's laws,an observation about electric current first made in 1845 and now included in virtually every textbook of elementary physics.
这里我是觉得 a colleague of his好像有问题,这个his是不是应该改成him?
