Language points

1.本课时我们学习的主要语法点是由wh- 和how 引导的特殊疑问句以及其对应的答语。

如：What do/does …? 

How often do/does …? 等。

e.g. What do you usually do on weekends?

你通常周末做什么？

I usually listen to music.  我通常听音乐。

e.g. How often do you go to the factory?

你多久去一次工厂？

I go to the factory twice a week.  我两周去一次。

How often do you exercise?                                      

你（你们）多久锻炼一次身体？ 

How often 助动词 do (does 或 did) 主语 do sth.?

疑问词 how often 是问频率（多久一次）,（在这里助动词 do /does/did是起帮助构成疑问的作用）与一般现在时或一般过去时连用, 回答一般是表示频率的副词或短语。

如： always, sometimes, quite often, never, every day, 

once a week, twice a month, three times a month, three or four times a month 等。

常考以how 引导的疑问短语

how often “多久一次 ”用于提问always ,once a day等。

how old    “多大年龄”用于提问ten years old 等。

how soon “多久以后”用于提问将来时中的in 时间段。

how long  “多长时间 ”用于提问一段时间。

how many “多少”  用于提问可数名词的数量。

how much “多少 ” 用于提问不可数名词的数量或提问价格。  

2. exercise

exercise v. 锻炼；exercise n. [U]运动；[C]练习

e.g. Let’ s do our exercises. 让我们做练习吧。

Walking is a good exercise.   散步是很好的运动。

Doing morning exercises is good for our health.

晨练有助于我们身体健康。

3. three times a week

表示次数的词或短语：once,twice,three times,four times…

对次数提问使用 how many times

区分表示频率的短语：once a day,twice a week,three times a month…

对频率提问用how often

4. Next week is quite full for me.   我下周比较忙。

full 忙的；满的；充满的          

同义词–busy

e.g. I’ve got rather a full week next week.  

我下周会非常忙。

My father has a very full life .

我父亲的生活很忙碌。

拓展：adj.饱的 

5. How come? 为什么呢？

这是英语中的一个口语，相当于汉语的“为什么”、“怎么会”等，既可以独立使用，也可在后接句子，来询问事情的缘由或状况。

e.g.  How come the sky is so blue today?

今天天怎么会这么蓝？

A: I didn’ t even eat lunch today.   我今天甚至没吃午饭。
