以下是引用yeede在2008-1-15 15:01:00的发言:102题的E怎么排出?第二遍了,还是错。文中的"at the tip of "是否有提示什么? (E) Researchers tested small areas of the anteater’s snout in order to ensure that only electroreceptors were responding to the stimulus. 不知楼上mm看的是否OG11版,里面对这个选项的解释是 "researchers did not know that electroreceptors existed before the experiment, so they could not have concluded the experiment in this way."挺好理解,就是实验前研究者并不知道electroreceptors的存在,所以不能说E是他们的实验目的 HOPE HELP! |
