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

 

【答案】

A

【解析】

試題分析：英語中數(shù)詞表示概數(shù)時(shí)，后面加s，和介詞of搭配使用。用原形時(shí)表示具體數(shù)字和數(shù)詞搭配使用。句意：一些科學(xué)家們說，讓機(jī)器人看起來像人一樣，和我們做一樣的事情，還需要很多年。結(jié)合語境可知本句中表示的是概數(shù)，故選A。

考點(diǎn)：數(shù)詞用法

點(diǎn)評：英語中關(guān)于hundred、thousand和million三個(gè)數(shù)詞的用法只需要記住一個(gè)原則就行。即；前有數(shù)詞則不加s，加s必加of。
