📌

考点一:动词的分类

🔹 按功能分类

类别说明举例
实义动词有实际意义,能独立作谓语eat, run, write, speak, buy
系动词后接表语,说明主语的状态或特征be, look, feel, sound, taste, smell, become, get, turn, keep
助动词帮助构成时态、语态、否定、疑问等do, does, did, have, has, had, will, shall
情态动词表示能力、许可、推测等can, could, may, might, must, should, need, dare

🔹 系动词的分类

类别常见系动词举例
状态系动词be(am/is/are)He is a student.
感官系动词look, sound, smell, taste, feelThe food tastes delicious.
变化系动词become, get, turn, grow, goThe leaves turn yellow in autumn.
保持系动词keep, stay, remainPlease keep quiet.
表象系动词seem, appearHe seems happy.

🔹 按是否需要宾语分类

  • 及物动词(vt.):后面必须接宾语。
    I like music.(like 是及物动词)
  • 不及物动词(vi.):后面不能直接接宾语,需加介词。
    He arrived at the station.(arrive 是不及物动词,需加 at)
⚠️ 易错提醒

系动词后接形容词,不接副词:
✅ The flower smells sweet.(sweet 是形容词)
❌ The flower smells sweetly.
✅ He looks happy.(happy 是形容词)
❌ He looks happily.

💡 速记口诀

实义动词有意义,系动词后接表语;
助动词来帮帮忙,情态动词表情态;
感官系动词五兄弟:看听闻尝摸;
系动词后用形容词,千万别用副词替。

📝 例题

选择正确答案:

1. The music sounds ______.(beautiful / beautifully)

2. The leaves ______ green in spring.(turn / are turned)

3. He ______ at the airport at 8:00 yesterday.(arrived / reached)

1. beautiful — sound 是系动词,后接形容词。

2. turn — turn 作系动词表示"变得",主动语态。

3. arrived — arrive 是不及物动词,后接 at;reach 是及物动词,可直接接宾语。

📌

考点二:动词的时态(上)

🔹 一般现在时

项目内容
构成主语 + 动词原形(第三人称单数加 -s/-es)
用法①经常性、习惯性动作 ②客观事实和真理 ③时刻表中的将来

例如:Look at the clouds. It is going to rain.(有迹象)
I think it will rain tomorrow.(预测)

💡 速记口诀

一般现在常习惯,三单动词加s/es;
一般过去用过去式,yesterday和ago是标志;

1. has gone to — Tom 不在这里,说明他去了北京还没回来。

2. has been in — since 2018 表示从2018年一直待到现在。

3. had left — "我到车站"是过去,"火车离开"在此之前,是"过去的过去"。

4. when — came back 是短暂动作,用 when。

📌

考点四:被动语态

🔹 被动语态的构成

被动语态由"be + 过去分词"构成,be 随时态变化:

时态被动语态形式举例
一般现在时am/is/are + doneEnglish is spoken in many countries.
一般过去时was/were + doneThe bridge was built in 2000.
一般将来时will be + doneThe work will be finished tomorrow.
现在进行时am/is/are + being + doneThe road is being repaired now.
现在完成时have/has + been + doneThe book has been translated into Chinese.
含情态动词情态动词 + be + doneThis problem must be solved at once.

🔹 主动语态变被动语态的步骤

  • ①将主动句的宾语变为被动句的主语
  • ②将谓语动词变为"be + 过去分词"
  • ③将主动句的主语变为 by 短语(可省略)

主动:Tom cleans the room every day.
被动:The room is cleaned (by Tom) every day.

🔹 不能用被动语态的情况

  • 不及物动词没有被动语态:happen, take place, break out, belong to 等
  • 系动词没有被动语态:look, sound, taste, smell, feel 等
  • 某些固定短语:sell well, wash easily, read well 等

例如:The accident happened yesterday.(不能说 was happened)
This kind of book sells well.(不能说 is sold well)

⚠️ 易错提醒

双宾语动词的被动语态:
give, teach, tell, show, send, buy, make 等可接双宾语。
主动:He gave me a book.
被动1:I was given a book (by him).(间接宾语作主语)
被动2:A book was given to me (by him).(直接宾语作主语)

💡 速记口诀

被动语态be加done,be随时态来变化;
宾变主来主变by,谓语变成be过分;
不及物动词无被动,系动词也不能变;
happen/take place要注意,sell well主动表被动。

📝 例题

将下列句子改为被动语态:

1. People speak English in many countries.

2. They will build a new school next year.

3. We must finish the work on time.

1. English is spoken in many countries.

2. A new school will be built next year.

3. The work must be finished on time.

📌

考点五:情态动词

情态动词用法举例

🔹 情态动词表推测

推测程度肯定句否定句

不可能(否定推测)can't + 动词原形

He must be a doctor.(他一定是医生)
He may be at home.(他可能在家)
He can't be at home.(他不可能在家)

⚠️ 易错提醒

must 的否定:
must 表"必须"时,否定用 needn't 或 don't have to(不必),而不是 mustn't。
mustn't 表示"禁止,不允许"。
— Must I finish it today? 我必须今天完成吗?
— No, you needn't. 不,你不必。(不能说 No, you mustn't.)
You mustn't smoke here. 你不许在这里吸烟。(表禁止)

💡 速记口诀

can能力may许可,must必须should应该;
推测must一定can't不可能,may/might也许可能;
must提问needn't答,mustn't表禁止;
had better最好做,need多用否定疑问句。

📝 例题

选择正确答案:
