observe
1.observe(无意间注意到)的宾语后面的不定式没有to。例如:I observed him go out.但假使把observe改作被动语态,那不定式便该有to。例如:He was observed to go out.
2.下面两句意思略有不同:
- I observed him go out.(我无意间注意到他出去。)
- I observed him going out.(我无意间注意到他正在出去。)
第二句着重在那个人正在出去而恰巧被我看见。参见notice 4
3.observe that...有时是“觉得…”,有时是“说…”,如He observed that I was wrong可能有两个意思:“他察觉到我是错的。”或“他说我是错的。”在有可能被人误解的时候,该避免用这结构。
