语法点:动词后接 -ing 与不定式 (Verb + -ing vs Verb + to)
英语里一个动词后面再接另一个动词时,有的要用 -ing 形式(动名词),有的要用 to + 动词原形(不定式),这主要由前一个动词决定,需要记忆。常接 -ing 的有:give up, keep on, enjoy, finish, mind, stop, avoid;常接 to 的有:want, urge sb., decide, hope, try, make an effort。介词后面一律用 -ing(after reading, of giving up)。个别动词如 stop、remember 两种都能接但意思不同。本课作者戒烟又复吸,全文用了 give up smoking, kept on offering, urged me to accept 等结构。
结构
| 类型 | 结构 | 例子 |
|---|---|---|
| 动词 + -ing | give up / keep on / enjoy / finish + doing | give up smoking, kept on offering |
| 动词 + to do | want / decide / hope / try + to do | decided to stop |
| 动词 + sb. + to do | urge / ask / tell / want + sb. + to do | urged me to accept a cigarette |
| 介词 + -ing | after / before / of / without + doing | after reading, someone giving up smoking |
| make + sb. + 动词原形 | make sb. do(无 to) | made me laugh |
| stop 两种 | stop doing(停止做)/ stop to do(停下来去做) | stop smoking / stop to smoke |
课文中的例句
- [句 1] After reading an article … I lit a cigarette to calm my nerves. — 介词 after 后接 -ing;to calm 是不定式表目的
- [句 4] I had all the usual symptoms of someone giving up smoking. — give up 后接 -ing;giving up 本身跟在介词 of 之后
- [句 5] My friends kept on offering me cigarettes and cigars. — keep on + -ing 表示不断重复做
- [句 6] They made no effort to hide their amusement … — make an effort + to do
- [句 9] When my old friend Brian urged me to accept a cigarette … — urge sb. + to do
- [句 12] … it is the easiest thing in the world to give up smoking. — give up 后必须用 smoking,不能用 to smoke

易错点
- ❌ I want to give up to smoke. → ✅ I want to give up smoking. — give up 后接 -ing,不接不定式。
- ❌ My friends kept on offer me cigarettes. → ✅ My friends kept on offering me cigarettes. — keep on 后必须用 -ing。
- ❌ Brian urged me accept a cigarette. → ✅ Brian urged me to accept a cigarette. — urge sb. 后要加 to do。
- ❌ After read the article, I lit a cigarette. → ✅ After reading the article, I lit a cigarette. — 介词后面用 -ing。
