Question

_________as one of the most important inventions of the time, the computer helps people living in different countries to do a lot of things.

A．Knowing	B．Known
C．To know	D．Know

Answer 1

B

解析試題分析：句意：電腦作為當(dāng)今最重要的發(fā)明之一，它幫助不同國家的人們做許多事情。分析語境可知，
Known as one of the most important inventions of the time為伴隨狀語從句。當(dāng)從句中主語和主句主語一致，且
從句謂語動(dòng)詞為be動(dòng)詞時(shí)，從句中的主語和謂語動(dòng)詞可省略。從句原句為the computer is known as one of the
most important inventions of the time,省略后成為Known as one of the most important inventions of the time。故
選B。
考點(diǎn)：考查省略句。
