助動詞的八年級英語上冊語法複習詳解

助動詞

1) leave的用法

1.“leave+地點”表示“離開某地”。例如: When did you leave Shanghai? 你什麼時候離開上海的?

2.“leave for+地點”表示“動身去某地”。例如:

Next Friday, Alice is leaving for London. 下週五,愛麗斯要去倫敦了。

3.“leave+地點+for+地點”表示“離開某地去某地”。例如:

Why are you leaving Shanghai for Beijing?你為什麼要離開上海去北京?

2) 情態動詞should“應該”學會使用

should作為情態動詞用,常常表示意外、驚奇、不能理解等,有“竟會”的意思,例如:

How should I know? 我怎麼知道?

Why should you be so late today? 你今天為什麼來得這麼晚?

should有時表示應當做或發生的事,例如:We should help each other.我們應當互相幫助。

我們在使用時要注意以下幾點:

1. 用於表示“應該”或“不應該”的概念。此時常指長輩教導或責備晚輩。例如:

You should be here with clean hands. 你應該把手洗乾淨了再來。

2. 用於提出意見勸導別人。例如:

You should go to the doctor if you feel ill. 如果你感覺不舒服,你最好去看醫生。 3. 用於表示可能性。should的這一用法是考試中常常出現的考點之一。例如: We should arrive by supper time. 我們在晚飯前就能到了。 She should be here any moment. 她隨時都可能來。

3) What...? 與 Which...?

1. what 與 which 都是疑問代詞,都可以指人或事物,但是what僅用來詢問職業。如:

What is your father? 你父親是幹什麼的?

該句相當於:

What does your father do?

What is your father's job?

Which 指代的是特定範圍內的某一個人。如:---Which is Peter? 哪個是皮特?

---The boy behind Mary. 瑪麗背後的那個男孩。

2. What...?是泛指,所指的事物沒有範圍的限制;而 Which...?是特指,所指的事物有範圍的限制。如: What color do you like best? (所有顏色) 你最喜愛什麼顏色?

Which color do you like best, blue, green or yellow? (有特定的範圍) 你最喜愛哪一種顏色?

3. what 與 which 後都可以接單、複數名詞和不可數名詞。如: Which pictures are from China? 哪些圖,片來自中國?

4) 頻度副詞的位置

1.常見的頻度副詞有以下這些:always(總是,一直)usually(通常)often(常常,經常)sometimes(有時候)never(從不)

2.頻度副詞的位置:

a.放在連繫動詞、助動詞或情態動詞後面。如: David is often arrives late for school. 大衞上學經常遲到。 b.放在行為動詞前。如: We usually go to school at 7:10 every day.我們每天經常在7:10去上學。

c.有些頻度副詞可放在句首或句尾,用來表示強調。如:Sometimes I walk home, sometime I rides a bike.有時我步行回家,有時我騎自行車。

r放在句首時,主語、謂語動詞要倒裝。如:Never have I been there.

5) every day 與 everyday 1. every day 作狀語,譯為“每一天”。如: We go to school at 7:10 every day.我們每天7:10去上學。

I decide to read English every day.我決定每天讀英語。

2. everyday 作定語,譯為“日常的”。

She watches everyday English on TV after dinner.她晚飯後在電視上看日常英語。

What's your everyday activity?你的日常活動是什麼?

6) forget doing/to do與remember doing/to do

et to do 忘記要去做某事。 (未做)

forget doing 忘記做過某事。 (已做)

The light in the office is still on. He forgot to turn it off.辦公室的燈還在亮着,它忘記關了。(沒有做關燈的動作) He forgot turning the light off. 他忘記他已經關了燈了。 ( 已做過關燈的動作)

Don't forget to come tomorrow.別忘了明天來。 (to come動作未做)

典型例題

---- The light in the office is still on.

---- Oh,I forgot___.

A. turning it off B. turn it off C. to turn it off D. having turned it off

答案:C。由the light is still on 可知燈亮着,即關燈的動作沒有發生,因此用forget to do sth.而forget doing sth 表示燈已經關上了,而自己忘記了這一事實。此處不符合題意。

mber to do 記得去做某事 (未做)

remember doing 記得做過某事 (已做)

Remember to go to the post office after school.記着放學後去趟郵局。
