be动词的用法
be (be/is/are/am/was/were) [bi:] vi 现在时 I am, you are, he is, we are, you are, they are (缩略式 I'm, you're, he's, we're, you're, they're), (否定缩略式 I'm not, isn't, aren't), 过去时 I was, you were, he was, we were, you were, they were (过去时否定缩略式 wasn't, weren't), 过去分词 been, 现在分词 being 英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。 “Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were. 在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)
行为动词 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。 ++及物动词用于被动语态。如: The meeting will be held in the afternoon.会议将在当天下午举行。
编辑本段不及物动词
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。
编辑本段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?
助动词功能
助动词(auxiliary)主要有两类:基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个:do, have和be;情态助动词基本的有十四个:may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to.had better 上述两类助动词的共同特征是,在协助主动词构成限定动词词组时,具有作用词的功能:
主谓一致
主谓一致是指: 1) 语法形式上要一致,即单复数形式与谓语要一致。 2) 意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。 3) 就近原则,即谓语动词的单复形式取决于最靠近它的词语, 一般来说,不可数名词用动词单数,可数名词复数用动词复数。 There is much water in the thermos. 但当不可数名词前有表示数量的复数名词时,谓语动词用复数形式。 e.g. Ten thousand tons of coal were proced last year. Large quantities of water are needed. In western countries, mountains of rubbish are thrown away each day. 1 并列结构作主语时谓语用复数 Reading and writing are very important. 注意: 当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and 此时连接的两个词前只有一个冠词。
