典型例题

　1）_____ some officials, Napoleon inspected his army.
A. Followed　 B. Followed by　 C. Being followed　 D. Having been followed

　答案B. Napoleon 与follow 之间有被动的含义。being followed除表达被动之外，还有动作正在进行之意。 followed

by（被…跟随）。本题可改为:With some officials following, Napoleon inspected his army.

　
　2）There was a terrible noise ___ the sudden burst of light.　
A. followed　 B. following　 C. to be followed　 D. being followed

　答案B. 由于声音在闪电后，因此为声跟随着光，声音为跟随的发出者，为主动。用现在分词。

　
　3）_______, liquids can be changed into gases.
A. Heating　 B. To be heated　 C. Heated　 D. Heat

　答案C.

本题要选一分词作为状语。现在分词表主动，正在进行的；过去分词表被动的，已经完成的。对于液体来说是加热的受动者，是被动的，因而选C。它相当于一个状语从句 When
it is heated，…

注意： 选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。
