_________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

试题分析：句意：电脑作为当今最重要的发明之一，它帮助不同国家的人们做许多事情。分析语境可知， Known as one of the most important inventions of the time为伴随状语从句。当从句中主语和主句主语一致，且 从句谓语动词为be动词时，从句中的主语和谓语动词可省略。从句原句为the computer is known as one of the most important inventions of the time,省略后成为Known as one of the most important inventions of the time。故 选B。
