Question

Thanks to the Internet, different kinds of information _____ in a short time.

A．can be learned	B．has been learned
C．can learn	D．has learned

Answer 1

A

解析试题分析：句意：幸亏网络，不同种类的信息在短时间里能够被得知。A. can be learned 能被得知； B. has been learned  已被得知；C. can learn 能得知；  D. has learned已得知。根据Thanks to the Internet可知网络能让人得知信息，故用情态动词can.结合句意，主语information与谓语learn之间是被动关系，故用被动语态。故选A。
考点：考查被动语态的用法。
