 复习时间介词:in .on . at. for 用法:

in+ 世纪、年、月份

on+ 日期、具体日期的(上、下、晚)、包含特定形容词的(上、下、晚)

at+ 时刻

for+ 时间段(强调句子谓语动词的持续性、不间断性)

例: Mr Smith walked into an old city in Beijing ______ a cold morning .

The doctor often tells children to sleep______ eight hours at night.

When did your mom arrive in Beijing ,Jim? ______ half past six.

2. I have to help my parents. 我必须帮助我的父母亲。

Have to +v原 ''不得不//必须、'' must+v原 ''必须'' .二者比较如下:

① have to有人称和数的变化,即第三人称单数用has to,其他人称用have to;而must没有人称或数的变化。

例:He has to go there to visit his aunt.他不得不去那里拜访他的姑姑。

② have to有时态的变化,must没有。

例:He had to study late for the math test.他不得不为数学测试而学到很晚。

③ have to强调客观上"不得不"做某事;(非本身愿意)

  must指主观上"必须"做某事。 (本身愿意)

例:We must study hard.我们一定要努力学习。主语We本身愿意

Students have to do so much homework every night. 主语students不愿意写这么多作业

3. How about+n// doing sth? ......怎样? (提建议/征求对方意见)

4. I have to go to the doctor. 我不得不去看医生。

  go to a doctor = see a doctor; 类似有 go to a dentist = see a dentist.

5. What a small party ! 多小型的一个聚会啊。

语法小解:感叹句

① 感叹句: 指表达喜怒哀乐等强烈感情的句子。一般可译为汉语的: ''........啊;........呀''

② 构成:主要由what 和how 来引导。初中阶段感叹句的基本句型如下:

   What + a/an+adj+ 可数名词单数 +(主+谓)

What感叹句: What +adj+ 可数名词复数+(主+谓) what修饰的中心词

What +adj+ 不可数名词 +(主+谓) 是 名词

How感叹句:How +adj/adv+(主+谓)

  

   How 修饰adj//adv

易考点+易错点:①感叹句引导词(what和how)的选择;② what感叹句中,因为对不可数名词的把握不清,所以极容易根据汉语思维选成what a /an.

I'm really busy this week. 这个星期我真的很忙。
