1. all修饰名词主语时,可放在主语和行为动词之前,但要放在be动词之后(但是若be动词是句子中的最后一个词时,all要放在be动词之前)。如:\x0d\x0a\x0d\x0aAll the boys study well. = The boys all study well. 孩子们都学习得很好。\x0d\x0a\x0d\x0aThey are all steel workers. 他们都是钢铁工人。\x0d\x0a\x0d\x0a—Are you Young Pioneers? 你们是少先队员吗?\x0d\x0a\x0d\x0a—Yes, we all are. 是的,我们都是少先队员。\x0d\x0a\x0d\x0a2. all指“三个(以上)的数目”,反义词是none;both指“两个数目”,反义词是neither。如:\x0d\x0a\x0d\x0aI have three brothers. All of them are college students. 我有三个哥哥,他们都是大学生。\x0d\x0a\x0d\x0aHe has two sisters. Both of them major in English. 他有两个姐姐,她们都主修英语。\x0d\x0a\x0d\x0a3. 不能说“all + 代词”,要说“代词+ all”或“all of + 代词”。如:\x0d\x0a\x0d\x0a误:All they like her.\x0d\x0a\x0d\x0a正:They all like her. /All of them like her. 他们都喜欢她。\x0d\x0a\x0d\x0a4. “All + 冠词(指示代词或物主代词)”=“冠词(指示代词或物主代词)+ whole”。如:\x0d\x0a\x0d\x0aall the world = the whole world全世界\x0d\x0a\猜纤x0d\x0aall my life = my whole life 我的一生\x0d\x0a\x0d\x0a注:all可修饰不可数名词或复数名词,the whole不可直接修饰不可数名词或复数名词,应用the whole of。如:\x0d\x0a\x0d\x0aall Shanghai = the whole of Shanghai 全上海\慧野x0d\x0a\x0d\x0aall ink = the whole of ink 所有墨水\x0d\x0a\x0d\x0aall his books = the whole of his books 他所有的书\x0d\x0a\x0d\x0a5. all用于否定句时通常表示部分否定,要表示全部否定可用no,none等。如:\x0d\x0a\x0d\x0aAll my friends cannot swim. 并非我所有的朋友都会游泳。\x0d\x0a\x0d\x0aNone of my friends can swim. 我所有的朋友都不会游泳。\x0d\x0a\x0d\x0aI don”t know any of them. 他们我都不认识。\x0d\x0a\x0d\x0a6. all不能与what连用,可把what改为that。例如:\x0d\x0a\x0d\x0a误:This is all what I want to say.\x0d\x0a\x0d\x0a正:This is all that I want to say. / This is what I want to say. 这就是我要说的全部。\x0d\x0a\x0d\x0a7. “all +地名”,表示“全??的穗碧仿人”;“the whole of +地名”表示“全??的地方”。如:\x0d\x0a\x0d\x0aAll America celebrate Independence Day on July 4. 7月4日全美国(人民)庆祝独立纪念日。\x0d\x0a\x0d\x0aHe has traveled the whole of America. 他已经游遍了全美国。\x0d\x0a\x0d\x0a8. “all +抽象名词”=“very +形容词”,前者语气更强。如:\x0d\x0a\x0d\x0aLittle Amy is all attention. = Little Amy is very attentive. 小埃米非常专心。\x0d\x0a\x0d\x0aHe is all kindness to us all. = He is very kind to us all. 他对我们大家非常亲切。\x0d\x0a\x0d\x0a9. at all作“完全;根本”解时,多用于否定句;用于条件句时表示“既然;即使”;用于疑问句时,作“到底;在任何程度上”解。如:\x0d\x0a\x0d\x0aIf it were not for the sun, we could not live at all. 如果没有太阳,我们根本不能生存。\x0d\x0a\x0d\x0aHave you read any of the article at all? 那篇文章你到底有没有读过一点
