译林版七年级下册 Unit 3 冠词（a /an/the）知识点梳理+分层专项练习

 

课前导学·基础知识梳理

 一、冠词的两大类别

英语冠词分为不定冠词 a/an 与定冠词 the。

1. 不定冠词 a / an

作用：泛指某一类人、事物里的任意一个，只能搭配可数名词单数。

- a：放在辅音音素开头的单词前面；

- an：放在元音音素开头的单词前面；

⚠️ 关键提醒：判断标准看单词发音，不是看拼写的元音字母。

课本例句品读：

① Look! Here is a cat. 看！这儿有一只猫。（第一次随便提及一只猫，泛指）

② There is an apple tree over there. 那边有一棵苹果树。

 

2. 定冠词 the

作用：特指双方都清楚的人或物、上文已经提到过的事物。

 课本中the的四类常用场景

① 前文先用a/an引出事物，下文再次指代这同一个事物

例：I have a pen. The pen is a present from Ben.

我有一支钢笔，这支钢笔是本送给我的礼物。

② 特指当下环境里双方心知肚明的具体事物

例：Can I open the window? 我可以打开这扇窗户吗？

③ 世上独一无二的事物、江河这类专有名词前要用the

例：The Yellow River is called the “Mother River” by Chinese people.

黄河被中国人称作“母亲河”；

I want to travel around the world. 我想要环游世界。

④ 部分标志性专有名词前搭配the

例：We will visit the National Stadium. 我们将要参观国家体育场。

 

 二、重点固定搭配：play 短语中的冠词规则（本课易混点）

1. 球类运动、棋牌类活动：play + 运动/棋牌名词，不加任何冠词

play football 踢足球　　play volleyball 打排球　　play chess 下国际象棋

2. 各类乐器（西洋乐器、二胡这类民族乐器）：play + the + 乐器名称，必须加the

play the piano 弹钢琴　　play the violin 拉小提琴　　play the erhu 拉二胡
