1) 表示动作中状态的词叫做动词。
2) 根据其在句中的功能,动词可分为四类,分别是:
实义动词(Notional Verb)、
定义:
实义动词与系动词是相对的,系动词亦称连系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。实义动词意思完全,能独立用作谓语。实义动词有及物动词和不及物动词(及物动词是指后面要求有直接宾语的动词;不及物动词指后面不需要跟宾语的动词) 即行为动词,表示动作的动词。它分为及物动词和不及物动词两种
[编辑本段]分类
简介
实义动词:及物动词(带宾语);不及物动词(不带宾语)。
及物动词
后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。如: I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。 “How long can I keep the book ?”Harry asked.哈里问:“这本书我可以借多久?” Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。 Crude oil contains many useful substances.原油含有许多有用的物质。
不及物动词
本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。如: Birds fly.鸟会飞。 It happened in June 1932.这件事发生于一九三二年六月。 My watch stopped.我的表停了。 She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。 3)兼作及物动词和不及物动词 英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况: a)兼作及物动词和不及物动词时,意义不变。试比较: Shall I begin at once?我可以立刻开始吗?(begin作不及物动词) She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词) When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词) They left last week. 他们是上周离开的。(left 作不及物动词) b)兼作及物动词和不及物动词时,有时意义不尽相同。如: Wash your hands before meals.饭前要洗手。 Does this cloth wash well? 这布经得起洗吗? 4) 与汉语的比较 有时英语动词的及物和不及物的用法,与汉语的用法不一样,请注意下列两种情况: a)有的动词在英语里只能用作不及物动词,而汉语则可用作及物动词,如arrive到达,agree同意,1isten听。英语里这些动词后面常接介词。如: We arrived at the railway station at noon.我们于中午到达火车站。(at不能省去)(比较:We reached the railway station at noon.) Everybody listened to the lecture with great interest.每个人都很有兴趣地听讲课。(to不可省去)(比较:We all heard the lecture.) Do they agree to the plan?他们同意这个计划吗?(to不可省去) b)有的动词在英语里能用作及物动词,而在汉语里则不能用作及物动词,如serve为…服务。 Our children are taught to serve the people wholeheartedly.我们的儿童被教以全心全意为人民服务
[编辑本段]实义动词的用法
实义动词词义完整,能独立作谓语,可分成:及物动词(transitive verb)和不及物动词(intransitive verb)。
1.及物动词要求有宾语
①Mr.Smith gave his wife twenty pounds for her birthday.史密斯先生给了他的妻子20英镑过生日。 ②He asked the teacher a few questions.他向老师问了几个问题。 ③We have friends all over the world.我们的朋友遍天下。 ④Children and young people like bright colors.孩子和年轻人喜欢亮丽的颜色。
2.不及物动词不要求宾语
① Most shops in Britain open at 9:00 A.m. and close at 5:00 or 5:30 in the evening .英国大部分商店九点开门,晚五点或五点半关门。 ②George's father lives there.乔治的爸爸住在那里。 ③Let's go home.我们回家吧。 ④The examination ended at 11:30 A.m.考试上午十一点半结束。
3.特殊实义动词
英语动词很多既是及物动词又是不及物动词,如 close, begin, study, leave, work等。 ①The post office closes at 9:00 p. m.邮局晚上9点关门。 ②Close the window, please.请关窗。 ③Shall we begin now?我们现在开始吗? ④ Bill began working as a sailor after he left school.比尔毕业后当水手。 ⑤They left yesterday.他们昨天离开的。 ⑥When did you leave Washington?你什么时候离开华盛顿的? ⑦The students study hard.这些学生学习努力。 ⑧The students study English and German.这些学生学习英语和德语。 ⑨He works in a supermarket.他在一家超市工作。 ⑩He works the machine on Mondays.他星期一操作这台机器。 3。实义动词,也叫行为动词。就我们现在所学的内容来讲,实义动词所在的句子中一般不存在be动词。也就是在含有实义动词的句子变否定句或疑问句时,一定不能用be动词。那么,实义动词究竟怎样用呢?正如be动词随着主语的变化可变为am、is、are一样,实义动词在肯定句中,也要随着主语的变化而变化。当主语为第三人称单数he,she, it时,实义动词要变为相应的第三称单数;当主语为非第三人称单数I, you(你), we,you(你们) they时,实义动词要用动词的原形。而在变否定句和疑问句时,不能直接在动词上变,而是要借助另一类动词:助动词do、does。 (1)肯定句: ① I have a blue book. ② He has a brother. ③ She wants to be a teacher. ④ They like to play basketball. (2)否定句:主语+don’t/doesn’t+动词原形。其中do/does为助动词,是来帮助实义动词构成否定或疑问句的,但加了do/does后,其后面的动词必须用动词原形。 ① I have a blue book.(变为否定句)→I don’t have a blue book. ② He has a brother. (变为否定句)→He doesn’t have ③ She wants to be a teacher. (变为否定句)→She doesn’t want to be a teacher. ④ They like to play basketball. (变为否定句)→They don’t like to play basketball. (3)一般疑问句:Do/Does +主语+动词原形+其他?句中加了do/does后,其后面的动词还是必须用动词原形。 ① I have a blue book.(变为一般疑问句)→Do you have a blue book? ② He has a brother. (变为一般疑问句)→Does he have a brother? ③ My brother does his homework before supper. (变为一般疑问句)→Does your brother do his homework before supper? ④ She wants to be a teacher. (变为一般疑问句)→Does she want to be a teacher? ⑤ They like to play basketball. (变为一般疑问句)→Do they like to play basketball? (4)特殊疑问句:特殊疑问词+一般疑问句? ① Your sister likes English best because it’s interesting. (对划线部分提问) →Why does your sister like English best? ② He does his homework before supper. (对划线部分提问)→When does he do his homework? 注意:当含有and引导的短语在句中做谓语或宾语,我们把这类句子变否定句时,必须把and变为or.如: (1)He can swim and dance. (变为否定句)→He can’t swim or dance. (2)My father likes English and math. (变为否定句) →My father doesn’t like English or math.
系动词(Link Verb)、
系动词
系动词亦称联系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。
说明:
有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语,例如:
He fell ill yesterday.
他昨天病了。(fell是系动词,后跟补足语,说明主语情况。)
He fell off the ladder.
他从梯子上摔下来。fell是实义动词,单独作谓语。
1)状态系动词
用来表示主语状态,只有be一词,例如:
He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
2)持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:
He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
3)表像系动词
用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
He looks tired. 他看起来很累。
He seems (to be) very sad. 他看起来很伤心。
4)感官系动词
感官系动词主要有feel, smell, sound, taste, 例如:
This kind of cloth feels very soft.
这种布手感很软。
This flower smells very sweet.
这朵花闻起来很香。
5)变化系动词
这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
例如:
He became mad after that. 自那之后,他疯了。
She grew rich within a short time. 她没多长时间就富了。
6)终止系动词
表示主语已终止动作,主要有prove, trun out, 表达"证实","变成"之意,例如:
The rumor proved false. 这谣言证实有假。
The search proved difficult. 搜查证实很难。
His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)
助动词(Auxiliary Verb)、
Do you 后面一般跟一般现在时句子,那么他的谓语就是动词原形,比如Do you like me?
Are you 提问的意思是你是。。。或者你在干什么,也就是说他后面不能跟动词原形,而需要加ING或者过去分词形式
比如Are you Mr long?
Are you talking to me?
英语的一般疑问句是将系动词或者助动词提前来表示的。
<br>1.用系动词提前:本身句子中含有be的,包括变形形式:are,is,am,过去时态的were,was
<br>2.用助动词提前:本身句子中没有be的,一般现在时(加do或does,本身没有do或does),一般过去时(加did,本身没有did),现在完成时(have提前,本身有have),过去完成时,本身有had)。
Do 是实意动词的一般疑问句疑问词
Are 是系动词的一般疑问句疑问词
Do you...........一般是问你做……?
Are you.........一般是问你是……?

实义动词(Notional Verb)、
定义:
实义动词与系动词是相对的,系动词亦称连系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。实义动词意思完全,能独立用作谓语。实义动词有及物动词和不及物动词(及物动词是指后面要求有直接宾语的动词;不及物动词指后面不需要跟宾语的动词) 即行为动词,表示动作的动词。它分为及物动词和不及物动词两种
[编辑本段]分类
简介
实义动词:及物动词(带宾语);不及物动词(不带宾语)。
及物动词
后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。如: I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。 “How long can I keep the book ?”Harry asked.哈里问:“这本书我可以借多久?” Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。 Crude oil contains many useful substances.原油含有许多有用的物质。
不及物动词
本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。如: Birds fly.鸟会飞。 It happened in June 1932.这件事发生于一九三二年六月。 My watch stopped.我的表停了。 She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。 3)兼作及物动词和不及物动词 英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况: a)兼作及物动词和不及物动词时,意义不变。试比较: Shall I begin at once?我可以立刻开始吗?(begin作不及物动词) She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词) When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词) They left last week. 他们是上周离开的。(left 作不及物动词) b)兼作及物动词和不及物动词时,有时意义不尽相同。如: Wash your hands before meals.饭前要洗手。 Does this cloth wash well? 这布经得起洗吗? 4) 与汉语的比较 有时英语动词的及物和不及物的用法,与汉语的用法不一样,请注意下列两种情况: a)有的动词在英语里只能用作不及物动词,而汉语则可用作及物动词,如arrive到达,agree同意,1isten听。英语里这些动词后面常接介词。如: We arrived at the railway station at noon.我们于中午到达火车站。(at不能省去)(比较:We reached the railway station at noon.) Everybody listened to the lecture with great interest.每个人都很有兴趣地听讲课。(to不可省去)(比较:We all heard the lecture.) Do they agree to the plan?他们同意这个计划吗?(to不可省去) b)有的动词在英语里能用作及物动词,而在汉语里则不能用作及物动词,如serve为…服务。 Our children are taught to serve the people wholeheartedly.我们的儿童被教以全心全意为人民服务
[编辑本段]实义动词的用法
实义动词词义完整,能独立作谓语,可分成:及物动词(transitive verb)和不及物动词(intransitive verb)。
1.及物动词要求有宾语

3.特殊实义动词
英语动词很多既是及物动词又是不及物动词,如 close, begin, study, leave, work等。 ①The post office closes at 9:00 p. m.邮局晚上9点关门。 ②Close the window, please.请关窗。 ③Shall we begin now?我们现在开始吗? ④ Bill began working as a sailor after he left school.比尔毕业后当水手。 ⑤They left yesterday.他们昨天离开的。 ⑥When did you leave Washington?你什么时候离开华盛顿的? ⑦The students study hard.这些学生学习努力。 ⑧The students study English and German.这些学生学习英语和德语。 ⑨He works in a supermarket.他在一家超市工作。 ⑩He works the machine on Mondays.他星期一操作这台机器。 3。实义动词,也叫行为动词。就我们现在所学的内容来讲,实义动词所在的句子中一般不存在be动词。也就是在含有实义动词的句子变否定句或疑问句时,一定不能用be动词。那么,实义动词究竟怎样用呢?正如be动词随着主语的变化可变为am、is、are一样,实义动词在肯定句中,也要随着主语的变化而变化。当主语为第三人称单数he,she, it时,实义动词要变为相应的第三称单数;当主语为非第三人称单数I, you(你), we,you(你们) they时,实义动词要用动词的原形。而在变否定句和疑问句时,不能直接在动词上变,而是要借助另一类动词:助动词do、does。 (1)肯定句: ① I have a blue book. ② He has a brother. ③ She wants to be a teacher. ④ They like to play basketball. (2)否定句:主语+don’t/doesn’t+动词原形。其中do/does为助动词,是来帮助实义动词构成否定或疑问句的,但加了do/does后,其后面的动词必须用动词原形。 ① I have a blue book.(变为否定句)→I don’t have a blue book. ② He has a brother. (变为否定句)→He doesn’t have ③ She wants to be a teacher. (变为否定句)→She doesn’t want to be a teacher. ④ They like to play basketball. (变为否定句)→They don’t like to play basketball. (3)一般疑问句:Do/Does +主语+动词原形+其他?句中加了do/does后,其后面的动词还是必须用动词原形。 ① I have a blue book.(变为一般疑问句)→Do you have a blue book? ② He has a brother. (变为一般疑问句)→Does he have a brother? ③ My brother does his homework before supper. (变为一般疑问句)→Does your brother do his homework before supper? ④ She wants to be a teacher. (变为一般疑问句)→Does she want to be a teacher? ⑤ They like to play basketball. (变为一般疑问句)→Do they like to play basketball? (4)特殊疑问句:特殊疑问词+一般疑问句? ① Your sister likes English best because it’s interesting. (对划线部分提问) →Why does your sister like English best? ② He does his homework before supper. (对划线部分提问)→When does he do his homework? 注意:当含有and引导的短语在句中做谓语或宾语,我们把这类句子变否定句时,必须把and变为or.如: (1)He can swim and dance. (变为否定句)→He can’t swim or dance. (2)My father likes English and math. (变为否定句) →My father doesn’t like English or math.
