be about to do sth…when结构,表示“正要做某事时”,“马上要做某事,就在这时”。此时when是并列连词,它引导的句子须放在后面。又如:He was about to tell everything when his father came back. |

请注意be about to…和be going to, be go do…的区别。另外还要注意be about to不可与某种时间状语连用。此处when是并列连词,而不是从属连词,因此这里不是主从复合句,而是并列句。在学习英语时,某些词或短语的用法较为特殊,我们必须牢记。这些地方也是经常作为考点出现的地方,因此我们更应留心。 |
