all的用法

all 用法小结 在英语学习中,我们经常会遇见all 这个单词｡它的用法较多,下面把中学课本中出现过的all 用法小结如下: 1. all 修饰作主语的名词时,其位置在主语和行为动词之前,但必须放在be 动词､助动词或情态动词之后｡当be 动词是句子中最后一个词时, all 要放在be 动词之前｡例如: All the boys study well. The boys all study well. They are all English teachers. (不说: They all are English teachers.) They would all have been invited if there had been room. (不说: They all would have been invited ...) all 也可以放在直接宾语或间接宾语之后,但这个宾语必须是us, you 等人称代词｡例如: I have eaten them all. (不说: I have eaten the cakes all.) — Are they English teachers? — Yes, they all are. 2. all指三个或三个以上的人或物“都”,其反义词是 none; both 指两个人或物“都”,其反义词是 neither｡ 例如: I have three brothers. All of them are sports fans. 比较: None of them are sports fans. He has two sisters. Both of them major in English. 比较: Neither of them majors in English. 3. 不说“all + 代词”,应说“代词 + all”或“all of + 代词”｡ 例如: 误: All they like English stories very much. 正: They all like English stories very much. 正: All of them like English stories very much. 但要注意: “all of + 名词”结构中的名词前面要用限定词 误: All of books belong to me. 正: All of the books belong to me. 正: All the books belong to me. 4. “all + 冠词/指示代词/物主代词”相当于“冠词/指示代词/物主代词 + whole.”｡ 例如: Hug all the world. (= Hug the whole world.) That is all my life. (= That is my whole life.) 注意: all 可修饰不可数名词或复数名词, the whole 不可修饰不可数名词或复数名词,如要修饰不可数名词或复数名词,则要将 all the whole 改为 the whole of 才行｡ 例如: I love all Shanghai. (= I love the whole of Shanghai.) The cat drank all the ink. (= The cat drank ...
