Adverbial Clause
1) when/while/as 的用法
when表示从句和主句动作同时发生,或先于主句动作;while表示从句的动作与主句动作同时发生,并且有延续的含义; as从句与主句动作相并发生,常译为“边……边……”
1. 时间状语从句注意点
When I was walking down the street, I saw some policemen. 当我沿着街道走的时候看到一些警察。
While the child was playing with his toys, his parents were watching TV. 这个孩子玩玩具的时候他的父母在看电视。
They shouted slogans as they passed the square.
他们一边穿过广场一边呼喊口号。
2) 含有关联词组hardly…when和no sooner…than的两种句子结构表示“一……就……”。当hardly 或no sooner为于句首时,要到装。
Hardly had he arrived when it began to snow. 他刚到天就开始下雪了。
Hardly had we walked into the hall when the lecture started. 我们刚走进大厅讲座就开始了。
No sooner had the boy reached the door than he came back. 这个孩子刚一走到门边就回来了。
3) 一些表示时间的名词词组, 如the moment, each time, every time, the first time, the year 等, 也用于引导时间状语从句, 这是它们担当着连接词的功能。
Each time he came, he would bring us a lot of flowers. 他每次来都给我们带很多花。
The first time he went to Shanghai, he paid a visit to his former teacher.
他第一次去上海时去拜访了他的老师。
The moment I saw him, I thought of his father. 我一看到他就想起了他的父亲。
2. 条件状语从句注意点
1) if 和unless是最长用的条件从句连接词, unless在意义上等于‘if…not’,并且语气较强。if 可用于虚拟条件句, unless 则一般不用于虚拟条件句。
