比如:我看电视.“看”就是谓语. 你正在上网.“上网”也是谓语. 再举几个英语句子吧:I see a girl.我看见一个女孩.“看见”"see"就是这个句子的谓语.而see也是个动词,所以就叫做谓语动词.She is very beautiful.她很漂亮."is"就是这个句子的谓语,也是动词. 而短语动词就是动词加小品构成的起动词作用的短语叫短语动词。例如: Turn off the radio. 把收音机关上。(turn off是短语动词) 短语动词的构成基本有下列几种: 1)动词+副词,如:black out; 2)动词+介词,如:look into; 3)动词+副词+介词,如:look forward to。构成短语动词的副词和介词都统称为小品词。 以后你会学到非谓语动词,顾名思义,非谓语动词也是动词,但不能作谓语,只能作主语、表语、宾语、补语、状语、定语。非谓语动词又分为动名词、不定式和分词。 1) 谓语动词在句中可单独作谓语,而非谓语动词不能单独作谓语。 Miss Mary teaches us English. 玛丽教我们英语。(teaches 动词作谓语) Mr.Victor came to our classroom to have a talk with us last week. 维克托先生上周来到了我们教室和我们谈话。 (to have a talk.... 不定式作目的状语) 2) 谓语动词受主语的人称和数的限制,而非谓语动词形式没有这种限制。 Larke likes the pop music. 拉克喜欢流行音乐。 (动词用单数第三人称形式,作谓语) Larke has nothing to do today. 拉克今天没什么事要做。(do 用原形,补充说明nothing) 非谓语动词的特征 1 如果非谓语动词是及物动词,后面须跟宾语。 Studying English is my favorite. 学习英语是我的爱好。(studying 后跟宾语) To help him is my duty. 帮助他是我的责任。(help 后跟宾语) 2 非谓语动词可以带有自己的状语或逻辑主语。 Working under such a condition is terrible. 在这样的环境下工作太可怕了。(under such a condition 是 working 的状语) It's too difficult for him to master English in such a short time. 他在这么短的时间内掌握英语太难了。(for him 作不定式的逻辑主语) 3 非谓语动词仍有语态和时态的变化。 I am sorry to have kept you waiting long. 对不起让你久等了。(to have kept...是不定式的完成形式) Seen from the mountain, the city looks much more beautiful. 从山上看,这座城市美丽多了。(Seen from...是分词的被动形式) 4 非谓语动词在句中可以当成名词或者形容词来使用。 Our coming made him happy. 我们的到来使他很高兴。(coming 起名词作用) There are two big swimming pools here. http://baike.baidu.com/view/79702.htm
