She was just ________ to open the window to let fresh air in, ________ she saw the lion.
[]
A．about, whileB．going, whenC．going, whileD．about, when试题答案
答案：D
解析：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。 |
