一、There be句型中be 的数 1. 在There be句型中,be后面的名词是句子的主语,因而be的数应与该名词的数保持一致。后面的名词为单数可数名词或不可数名词时,be应用is;后面的名词为复数可数名词时,be应用are。如: There's some milk in the bottle. There are many children in the park. 2. be后面的名词为不可数名词,但该不可数名词的前面有表示量的可数名词对其进行修饰时,be的数要与该可数名词保持一致。如: There are three bottles of milk on the table. 3. 当后面的名词不止一个时,be的数应按“就近”原则来确定。如: There is a table, four chairs and a small bed in the room. 二、There be句型中的动词变化 There be句型中的be还可换为其它动词,如stand, lie, live, appear等,从而使语言更加生动形象。如: Many years ago, there lived an old man ... There appears to be a mistake. 三、There be句型的各种时态 There be句型通过be动词的变化还可以构成各种时态。反意疑问句中的助动词要与各种时态相呼应。如: There will be a new film at the cinema, won't there? There have been great changes in your hometown, haven't there? 四、There be与have的区别 There be结构与充当实义动词的have都可作“有”讲,但have作“有”讲时,表示所有关系,即“拥有;占有”,而There be结构表示客观上的存在,不说明所有关系。试比较: Mrs Green has three children.(说明三个小孩归Mrs Green所有) There are three children under the tree.(说明树下存在三个小孩) (文/朱孔仁 刘世一 王安新;英语辅导报初三普及版04—05学年度第22期;版权归英语辅导报社所有,独家网络合作伙伴新浪教育,未经许可,不得以任何形式进行转载。) |
