语法要点
“having been” 的使用

“Having been” 是一个过去完成分词结构,用来表示某个动作或状态在过去的某个时刻之前已经完成,并对现在产生了某种影响。这个结构通常用来强调在过去某个时刻之前发生的动作或状态。
例句:
- Having been invited to the party, I still didn’t go. (尽管我已经被邀请参加派对,但我还是没有去。)
与其他时态对比:
结构 | 解释 | 例句 |
---|---|---|
Having been | 过去完成分词,强调某事发生在过去,并对现在有影响。 | Having been to that restaurant, I can say it’s really good. |

“look” 和 “make” 的区别
解释:
“Look” 和 “make” 都可以用来引导补足语,但它们的作用不同。
- “Look” 是系动词,后接形容词或表语,描述主语的状态或外貌。
- “Make” 是使役动词,后接宾语和补足语,表示某事或某物的状态被改变。
例子:

- “look” 用作系动词,后接形容词。
She made the room look bigger. (她让房间看起来更大。)
- “make” 是使役动词,后接宾语和补足语。

- 这里 “that he is coming” 是宾语从句,作为动词 “know” 的宾语。
It’s obvious that she is happy. (显然她很高兴。)
- 这里 “that she is happy” 是主语从句,作为句子的主语。
对比:
