Question

Some scientists think that it may take _________years to make robots look like people, and do the same things as us.
A. hundreds of   B. two hundreds of   C. two hundreds   

Answer 1

A

試題分析：句意：一些科學(xué)家認(rèn)為制造像人一樣的機(jī)器人跟我們做一樣的事有可能花費(fèi)數(shù)百年時(shí)間。在hundred前面有具體數(shù)詞時(shí)，不用復(fù)數(shù)，不連用of，但前面沒有具體數(shù)詞時(shí)即表示概數(shù)時(shí)，必須使用復(fù)數(shù)形式并連用of，所以選A。
