(3) be about to do...when...刚要做……突然……I was just about to go swimming when our guide saw me and shouted at me.
该句中的“when”表示“正在这时”,相当于and just或and at that time. 这时不能用while / as 替换。
常见句型:(1) be about to do sth when... (2) be doing sth when... (3) be on the point of doing sth when...
【】We were swimming in the lake ____ suddenly the storm started.
A. when
B. while
C. until
D. before
【解析】选A. "when" 作连词,表示“正在这时”。意为“我正在湖中游泳,突然暴风雨来了。”只有when才能用于这种句型A. why
B. where
C. when
D. while
【解析】选C。主句用了be about to 结构,意思是“正准备做…”,与when 引起的从句连用
3).I

.
A.went; was occurring
B. went; occurred
C.was going; occurred
D.was going; had occurred
