三、注意分清是系表結構還是被動語態(tài)

過去分詞用作表語時，其動作意味很弱，在功能上更接近形容詞，它不僅可用于系動詞be之后，也可根據需要用于其他系動詞之后。如：

She looked astonished at the news. 聽到這消息她顯得很吃驚。

It took them a long time to grow used to getting up in the middle of the night. 他們花了很長時間才慢慢地習慣于午夜起床。

被動語態(tài)中的過去分詞動作意味較強，它只能與助動詞be（有時可能是get）構成被動結構，不宜用于其他動詞之后。如：

The food was cooked last night. 飯是昨天晚上做的。

After the operation she was taken to the recovery room. 手術后，她被推進了恢復室。

所以如果語義需要，其后可以接表示動作執(zhí)行者的by短語。如：

When their mother was ill the children were looked after by neighbours. 孩子們的母親生病時，他們由鄰居們照顧。

比較：

I was worried about you all night. 我整夜為你擔心。（系表結構）

I was worried by the mice all night. 我被老鼠攪擾了一整夜。（被動語態(tài)）
