scientists belive that X——(in other words)that Y。这里就存在着平行结构,其实(破折号)的作用是that is to say 的意思,并且省略了scientists believe,把这句话补充完整就是: Some anthropologists believe that the genetic homogeneity evident in the world’s people is the result of a "population bottleneck" ,(that is to say,some anthropologists believe)that at some time in the past our ancestors suffered an event that greatly reduced their numbers and thus our genetic variation. 所以that是不能省的。

1.破折号这里表示解释而不是敲掉,所以-- 等于in other words。那么就需要有平行,这里的believe that...--that... 2. and thus our genetic variation 指的是and thus reduce our genetic variation

破折号可以解释前面整句话,也可以解释前面就近的名词。 划线的that和前面的that平行。A选项没有that,暧昧。

当破折号后面是完整句子,说明修饰的是前面一句话,而这里前面是一个that引导的分句,所以破折号后面也要加出引导词that

scientists belive that X——(in other words)that Y。这里就存在着平行结构,that不可省略。at some time做状语at不可以省略。

1.破折号这里表示解释而不是敲掉,所以-- 等于in other words。那么就需要有平行,这里的believe that...--that... 2. and thus our genetic variation 指的是and thus reduce our genetic variation GMAT中 宾语从句中that永远不能省略!!! that不可以省略的原因是因为引导的是"population bottleneck" 的同位语,而同位语的that是不可以省略 平行!!!谨记谨记!!!

破折号后面的句子解释说明前面的内容,所以主语还是some anthropologists不是后面的 our ancestors, 省略了谓语动词believe ,that不能省;their numbers 和 our genetic variation 平行结构,所以不能numbers were reduced的被动语态

that不可以省略的原因难道不是因为引导的是"population bottleneck" 的同位语,而同位语的that是不可以省略的吗?
