初中英语语法—动词
一、行为动词 (Action Verbs)
定义:表示具体动作或行为的动词,能独立作谓语。
分类与用法:
及物动词 (Transitive Verbs, vt.)
必须接宾语,否则句意不完整。
例句:
She eats an apple. (直接宾语)
He gave me a book. (间接宾语 + 直接宾语)
不及物动词 (Intransitive Verbs, vi.)
无需宾语即可表达完整意义。
例句:
Birds fly.
The sun rises.
兼作及物和不及物动词
部分动词根据语境改变性质。
例句:
She sings beautifully. (vi.)
She sings a song. (vt.)
常见错误:
误用不及物动词带宾语(如:✗ He runs a marathon every morning. → ✓ He runs every morning.)
二、连系动词 (Linking Verbs)
定义:连接主语与表语,说明主语性质、状态或身份,无实际动作。
分类与用法:
Be动词
am/is/are(现在时);was/were(过去时)
例句:
She is a teacher.
They were happy.
感官动词
look(看起来)、sound(听起来)、taste(尝起来)、smell(闻起来)、feel(感觉)
例句:
The cake smells delicious. (+形容词)
The story sounds interesting.
变化类动词
become(成为)、get(变得)、turn(转变)、grow(逐渐变得)
例句:
Leaves turn yellow in autumn.
He became famous.
状态保持类
stay(保持)、remain(仍然)、keep(保持)
例句:
Please keep quiet.
She remained calm.
注意事项:
后接表语(形容词/名词),而非副词(如:✓ She looks happy. ✗ She looks happily.)
三、情态动词 (Modal Verbs)
定义:表示能力、许可、推测等,需与动词原形连用,无人称/数变化。
常见情态动词及用法:
can/could
能力(I can swim.)
请求许可(Can I open the window?)
推测(It could be true.)
may/might
许可(May I leave?)
可能性(It may rain.)
must
必须(You must finish homework.)
肯定推测(She must be tired.)
should
建议/义务(You should study harder.)
will/would
意愿/请求(Will you help me? Would you like tea?)
特殊规则:
否定形式:直接加not(can → cannot/can't;must → must not/mustn't)。
过去式用法:could/might/would可表委婉(Could you pass the salt?)。
must vs. have to:must表主观,have to表客观(I must exercise. vs. I have to wear a uniform.)。
need/dare可作情态或实义动词:
情态:Need I go? / Dare he speak?
实义:I need to go. / He doesn’t dare to ask.
四、助动词 (Auxiliary Verbs)
定义:辅助构成时态、语态、疑问句、否定句,无实际意义。
分类与用法:
Be动词
构成进行时态:be + V-ing
She is reading.
构成被动语态:be + 过去分词
The book was written by him.
Do动词
构成一般现在/过去时的疑问句和否定句:
Do you like apples?
He doesn’t know the answer.
用于强调:
I do want to help!
Have动词
构成完成时态:have + 过去分词
They have finished the work.
注意事项:
助动词后接原形动词(如:✓ He is running. ✗ He is runs.)。
否定句:助动词 + not(如:She has not arrived.)。
易混淆点总结
系动词 vs. 行为动词
系动词后接形容词(✓ The flower smells good.);行为动词后接副词(✓ She smells the flower carefully.)。
情态动词的否定推测
must表肯定推测(He must be at home.);can’t表否定推测(He can’t be at school.)。
助动词在疑问句中的位置
助动词提前(Did he go?);无助动词时需添加(✗ Went he? → ✓ Did he go?)。
