M4U3重点词汇句型语法温习

1.掌握M4U3重点词汇，能在详细语境中灵敏运用所学词汇及句型。

学习目的 2.掌握have的用法。

3.熟习人称，并学会be动词的用法。

教学内容

1、 上次课后稳固作业温习；

2、 互动探求

教学建议：先生依据图片可以发现，下面的两幅图片，左图中It has a flower。意为〝它有一朵花〞，右图中的句子I have some flowers。意为〝我有一些花〞。从这两个句子我们可以看出：have和has都是表示〝有〞，has是have的第三人称双数方式。

看图片，看看have和has有什么不同！

【知识梳理1】

Words 单词

1．leaf 名词 叶子

[例句] The leaf is green．这片叶子是绿色的。

The tree has no leaf in winter．冬天，这棵树光秃秃的。

Sentences 句子

1．Look at the plant. It has leaves．看这株植物。它有叶子。

Look at… 是个祈使句。Look at前面直接接某人或某物。the是定冠词放在名词plant前，表示特指。例如：

Look at me.看我。

Look at the tree over there.看那里的那棵树。

It has… 意为〝它有……〞，it为第三人称双数，其后动词也运用第三人称双数has。例如：

It has lots of nuts．它有很多坚果。

It has a beautiful tail:它有一个美丽的尾巴。

2．They are thin and short．它们又细又短。

They are…意为〝它们是……〞(they在文中指植物的根)，主语是they，其后be动词相运用双数方式are。thin和short都是描画词，在句中作表语，说明主语的外形特点。例如：

They are tall-and thin,他们又高又瘦。

They arc fat and short.他们又胖又矮。

3．It is rainy．〔天〕下雨了。

【知识梳理2】

Grammar 语法

I. have的用法

(1) have的含义

从下面两幅图中我们知道：have在不同句中所表达的意义有所不同，左图表示拥有全体的一局部，右图表示拥有某样东西。

(2) have的用法

当表示〝有〞时，假设主语是第三人称双数( he/she/it)，谓语就用has。其他状况下，如主语是I，you，they，we或是其他一些双数方式，谓语就用have。例如：

You have two big eyes．你有两只大眼睛。

She has two big eyes. 她有两只大眼睛。

为了让小冤家更清楚地了解have和has与人称代词之间的关系，见以下图：

II. be动词：is&are

It is/They are/We are.., 意为〝它是／它们是／我们是……〞。本学期，我们曾经学过很多be动词的详细用法。我们要留意的是，be动词的方式应与主语坚持人称和数的分歧。例如：

It is a cat.它是一只猫。

They are my friends．他们是我的冤家。

【例题精讲】

例1：Tom has a big family. His family are very friendly. Tom有一个小家庭，他的家人都是很有好的。

例2：The dog has two big eyes. It is lovely. 这只小狗有两只大眼睛，它很心爱。
