  八年級英語必考語法點梳理+練習

  【運用】

  You ________ ________ your mother with housework.

  2. 我能參加校籃球隊的選拔活動嗎?

  ________ I ________ ________ for the school basketball team?

  3. 你不應該總拿自己和別人比較。

  Ⅱ. 按要求改寫下列句子,每空一詞。

  4. Could you please open the windows? (改為否定句)

  Could you please ________ ________ the windows?

  5. Jenny should see the doctor and get an X-ray. (對劃線部分提問)

  ________ ________ Jenny ________?

  【梳理】

  should后接動詞原形,其否定形式是should not,常縮寫為shouldn’t。

  含should的肯定句變為一般疑問句時,應將should提到句首,其肯定回答為“Yes, 主語+should”,否定回答為“No, 主語+shouldn’t”。

  含should的句子常表示責任、義務或提出建議等。

  Could you please …?意為“請你……好嗎?”表示請求對方做某事,其肯定回答常用Yes, sure / Certainly / Of course等,否定回答常用Sorry, I can’t / Sorry, I’m afraid not / I have to …等。

  Could you please …?的否定形式是在please后面加not。另外,Could I / we …?意為“我/我們可以……嗎?”表示請求得到對方的允許,其肯定回答常用Yes, you can /Yes, sure等,否定回答常用Sorry / No, you can’t等。

  【答案】

  Ⅰ. 1. should help

  2. Could; try out

  3. shouldn’t; compare

  4. Could you please

  5. Should I go; should

  Ⅱ. 1. shouldn’t; any

  2. Yes; can

  3. Should; take

  4. not open

  5. What should; do

  動詞不定式

  【運用】

  用所給動詞的適當形式填空。

  1. It took the workers ten months ________ (build) this bridge.

  2. Peter offered ________(teach) them how to swim.

  3. Did you hear Mom and Dad ________(go) out just now?

  4. He studied hard ________(get) better grades in the final exams.

  5. We should not let this kind of thing ________(happen) again.

  6. The Internet makes it possible for many people _______(work) at home.

  【梳理】

  動詞不定式由“to+動詞原形”構成,在句中可作賓語、賓語補足語、狀語和主語等。

  動詞不定式可在句中作動詞d e c i d e , refuse, hope, offer等的賓語。

  動詞不定式可在句中作賓語補足語,這類動詞有advise, invite, ask等;動詞不定式作使役動詞和感官動詞的賓語補足語時,應省略to。

  動詞不定式可在句中作目的狀語。

  動詞不定式可在句中作主語,常用it作形式主語,真正的主語(即動詞不定式)放在句尾。

  【答案】

  1. to build

  2. to teach

  3. go

  4. to get

  5. happen

  6. to work

  讓步、目的和時間狀語從句

  【運用】

  將下列句子翻譯成英語。

  1. 盡管陽光燦爛,但天氣不暖和。

  2. 我會把鑰匙給你,這樣你就可以自己進去。

  3. 孩子們跟著音樂跳舞直到音樂停止。

  4. 直到離開學校,他們才意識到學習的重要。

  【梳理】

  讓步狀語從句常由although, though等詞引導,一般情況下,although可以與though互換使用,但二者不能與but同時出現在一個句子中。

  目的狀語從句常由so that, in order that等短語引導。

  時間狀語從句常由until, when, while等詞引導。until用在肯定句中,意為“直到……為止”,常與延續性動詞連用;until用在否定句中,意為“直到……才……”,常與終止性動詞連用。

  【答案】

  1. Although / Though the sun is shining, it isn’t warm.

  2. I’ll give you the key so that you can get yourself in.

  3. Children danced to the music until it stopped.

  4. They didn’t realize the importance of study until they left school.

  2. Linda was sleeping when Susan arrived. (改為否定句)

  3. They were playing basketball at 4:00 pm yesterday. (改為一般疑問句)

  ________ they ________ basketball at 4:00 pm yesterday?

  4. She was making dinner when her sister was cleaning the room. (對劃線部分提問)

  ________ ________ she ________ when her sister was cleaning the room?

  【梳理】

  過去進行時由“was / were + V-ing形式”構成,表示過去某個時刻或某一時間段正在進行的動作。

  過去進行時常與表示過去某一特定時間的狀語連用,如at that time, at this time yesterday, all night, from 8 to 10 this morning等,也可與when / while引導的時間狀語從句連用。

  【答案】
