一全文逐句语法解读
本课围绕 失物招领,重点是 名词性物主代词(mine / yours)与 belong to,以及 It's got / It's 的区别(= it has / it is)。
¶ 1 · 名词性物主代词(句 5、6)
| 句子 | 语法点 |
| Is this case yours? | 物主代词 yours = your case,后不再接名词 |
| No, that's not mine. | mine = my case;名词性物主代词可独立使用 |
| What about this one? | What about…? 表“……怎么样”,用于提出建议或询问 |
¶ 2 · it's got 与 it's(句 3、8)
| 句子 | 语法点 |
| it's got a zip | It's got = It has got,表“有” |
| It's a small blue case | It's = It is,注意二者的区别 |
| This one's got a label. | one's got = one has got |
¶ 3 · 一般过去时与完成时(句 1、19、20)
| 句子 | 语法点 |
| I left a suitcase on the train the other day. | leave → left;the other day 表“前几天”,与过去时连用 |
| This case doesn't belong to me! | belong to + 人,表“属于”;不用进行时 |
| You've given me the wrong case! | 现在完成时表已产生的结果(箱子拿错了) |
二固定搭配与重点词组
| 短语 | 用法与例句 |
| the other day | 前几天。与一般过去时连用。 |
| belong to | 属于。belong to sb.,不能用进行时。 |
| a label on the handle | 提手上的标签。on 表“在……上”。 |
| What about this one? | 这只怎么样?用于询问或提议。 |
| Here you are. | 给你。(递东西时的常用语) |
| It's got a zip. | 它有拉链。It's = It has,不是 It is。 |
三语法核心总结
- yours / mine 是名词性物主代词,相当于“形容词性物主代词 + 名词”,可独立使用。
- It's got = It has got(有);It's = It is,两者不可混淆。
- belong to 表“属于”,一般不用进行时。
