{01}He was busy writing a story, only ______ once in a while to smoke a cigarette.
A.to stop
B.stopping
C.to have stopped
D.having stopped
解析:句意:他忙着编故事,偶尔停下来吸只烟。此题容易错选A。但only to do 表结果,人、而根据题意可知,此处表伴随且stop 几乎与was busy 同时发生,故用B,而having stopped 表示此动作限于谓语动词发生,与题意明显不符。 本题选B。 {02}Nowadays sending e-mails to each other is a way many a student _______ what they think.
A.conveys
B.delivers
C.express
D.account
解析: convey 表达Words can’t convey my feelings.言语无法表达我的心情. 本题选A。
