318. It is the species-typical behavior that sets humans completely apart from all other animals.
译文
正是这种典型的物种行为,将人类与其他动物完全区别开来。点睛
it is...that...是常用的强调句型。它一般强调主语、宾语和状语(以时间状语和地点状语为多),将被强调部分置于it is与that之间。如:It is he that is right. 对的人是他。
考点归纳
关于强调句型的几点补充:
1)如果被强调部分是人,该句型可以是it is...that...或者it is...who...。如:
It is Miss Gao who teaches us English. 教我们英语的是高女士。
2)如果被强调部分是人的宾语时,也可以变为it is...whom...。如:
It is Jonathan whom Professor Lee praises all the time. 李教授经常表扬的人是乔纳森。
3)如果被强调部分是事物或事情的情况,则常用it is...that...。但是。如果被强调部分是时间状语或地点状语,就只能是it is...that...,而不能用it is...when...或者it is...where...。如:
It was a month ago that mum picked you up in front of the zoo. 妈妈在动物园门口接你,那是一个月前的事了。
It was in the museum that Li Lei met your elder brother last week. 上星期,李磊是在博物馆碰到你哥哥的。
短语set...apart from意为“使……与众不同(或者优于其他)”。如:
Her clear and elegant prose sets her apart from most other writers. 她的散文简练而优美,多数作者都不及她。
与set有关的短语还有:
1) set off意为“使爆炸”。如:
Those fireworks could be set off by the slight spark. 一点小火星就可能让烟花爆炸。
set off还可表示“出发;启程”。如:
We planned to set off at five in the morning. 我们计划早上5点出发。
2) set up意为“建立,创立”。如:
A new government was set up after the war. 新政府于战后成立。
3) set down意为“使下车”。如:
The bus stopped to set down an old lady. 公共汽车停下来,让一位老太太下车。
