在英语中,动名词(verb + ing) 可以放在句首,尤其是在强调句或强调结构中,用来突出某个动作或状态。
✅ 一、动名词放在句首的结构
结构:
It is/that + 动名词 + that/who + 其他成分
✅ 二、常见用法
1. 强调句(强调动作或状态)
- It is / that + 动名词 + who / which + 其他成分
- 例句:
- It is eating that makes me feel hungry.(吃是让我感到饥饿的原因。)
- It is swimming that I like most.(游泳是我最喜欢的活动。)
2. 强调动作或状态(非强调句)
- It is + 动名词 + that + 其他成分
- 例句:
- It is working hard that he is successful.(努力工作是他成功的原因。)
- It is studying that keeps me awake.(学习让我熬夜。)
✅ 三、注意事项
- 动名词 不能单独作主语,必须与 it is 或 it is + 名词 结构搭配。
- 动名词 可以作主语,但需注意搭配是否正确。
- 动名词 也可以作宾语,但需搭配动词(如:to study, to enjoy 等)。
✅ 四、例句总结
