  • 终于清楚七年级英语be动词的用法

    be动词都有am/is/are/was/were,那么,它们的具体用法是什么呢?下面小编告诉你七年级英语be动词的用法,大家一起来看看吧! 七年级英语be动词的用法: 1. Be动词有三个,am,is还有are。 我用am,你用are,s跟着他她它,复数全部都用are。 如果遇到过去时,was来把am,is替,were来把换掉动词are

We found him a good job.=We found a good job for him. 我们为他找了份好工作。 比较下面一句(found 后为复合宾语): We found him a good teacher. (=We found that he was a good teacher.) 我们发现他是位好老师。

I went to her house but I found her out. 我到她家发现她不在家。 用作宾语补足语的副词通常只能是in, out, up, down, upstairs, downstairs等表示处所的副词小品词,而不能是其他普通副词。 (4) 宾语+不定式作宾语补足语。如: He found the patient to be a small boy. 他发现病人是一个小男孩。 用作宾语补足语的不定式通常为to be(且通常可以省略),但当find用于被动语态时,可以用其他动词。如: Her blood was found to contain poison. 她的血液里被发现有毒。 He was found to have helped himself to public money. 他被发现挪用了公款。 (5) 宾语+现在分词作宾语补足语。如: I found him lying on the floor. 我发现他躺在地板上。 I found him standing at the door. 我发现他正站在门口。 (6) 宾语+过去分词作宾语补足语。如: He found the door locked. 他发现门锁上了。 He found the city much changed. 他发现这个城市发生了巨大的变化。 (7) 宾语+介词短语作宾语补足语。如: We found her in tears. 我们发现她在哭泣。 We found the map quite out of date. 我们发现这地图已完全过时。 另外还要注意“find+形式宾语it+宾语补足语”结构。如: I find it easy to get on with her. 我发现她很容易相处。 He found it easy to earn extra money. 他发现赚点外快很容易。 I found it interesting being back at school again. 我发现再次回到学校很有意思。 3. 其后有时可接 that 从句。如: I found that the book was very interesting. 我发现这本书很有趣。 They found that he was no longer working there. 他们发现他已经不在那儿工作了。 He found (that) no one could answer his question. 他发现没有人能回答他的问题。 When he arrived, he found that she had gone. 当他到达时,他发现她已经走了。 后接 that 从句时,只要句型适合且不影响原意,有时可转换成复合结构,如上面的前面两句可转换为: I found the book very interesting. They found him no longer working there. 但是,上面的最后两句不适合这种转换,因为从句中用了情态动词或完成时态。 动词miss的两条重要用法: 1. 表示错过或避免做某事,其后习惯上接动名词作宾语,不接不定式。如: I just missed burning my hand. 我差点把手烫了。 He narrowly missed being seriously injured. 他差点受了重伤。 表示怀念做过的某事,其后习惯上也接动名词作宾语,不接不定式。如: I miss living in the country. 我怀念以前住在乡村的日子。 I miss you bringing me cups of tea in the mornings! 我常怀念早晨你给我送茶的情景! 2. 表示“丢失”,通常用其现在分词(转化为形容词)作表语或定语。如: The book has two missing pages [two pages missing]. 这本书缺两页。 The child has been missing for a week. 这孩子下落不明已有一周了。 注意不能用过去分词转化来的形容词,如: 误The child has been missed for a week. 动词follow 的用法与搭配: 1. 表示“跟随”,可用作及物或不及物动词。如: Follow close behind. 紧跟在后面。 Summer follows spring. 春去夏来。 The dog follows me wherever I go. 我不论到哪里,这狗都跟着。 表示某人或某物跟在另一人或另一物后面,一般不与介词behind 或after 连用,以免构成用词重复(尽管偶尔可见到这类用法,但在现代英语中很少见,初学者最好不用)。但有时可后接用作副词的behind。如: You go ahead. We’ll follow behind. 你们先走,我们随后就来。 2. 有时与there搭配使用, 构成类似there be的结构。如: There followed a long silence. 然后是一阵冗长的沉默。 There will follow an interval of five minutes. 随后将有5分钟休息。 3. 不要按照汉语习惯,将汉语表达中的“跟着某人做某事”直译为 follow sb to do sth, 而应根据情况选用适当的句型。如: 我跟他去了车站。 误:I followed him to go to the station. 正:I followed him to the station. 我跟着他读生词。 误:I followed him to read the new words. 正:I read the new words after him. 4. follow的用法很多,除表示“跟着”外,还可表示“听从”“遵循”“沿着”“仿效”“听懂”“明白”等义。如: Do you follow me? 你能听懂我的话吗? Follow the traffic rules. 遵循交通规则。 We should follow his advice. 我们应该听他的劝告。 He followed his sister’s example and went to college. 他效仿他的姐姐也进了大学。 Follow this road until you get to the corner, then turn left. 沿着这条路走到拐角处,然后向左拐。
