考点一:动词be的形式
动词be常用的形式有以下几种: 1. 动词be在各种时态中的形式:现在时am,is,are;过去时was1,were;将来时will / shall2 be,would / should be或am/ is / are going3 to be,was / were going to be;完成时have / has / had4 been; 2. 与情态动词连用,构成“there +情态动词+ be”的形式; 3. 与seem,appear,used6 to等表示状态的词语连用,构成“there seem5(s) / appear(s)/ used to be…”; 4. “There be…”句式中的be有时用come,enter,follow,arrive,seem,happen等动词代替,但不能用have代替。例如: There happened to be nobody8 in the room. 碰巧那时房间里没有人。 [试题精选] 1)There _________ many new words in Lesson One. It is very easy. A. is B. aren't C. isn't D. are (2005年南通市) 2)There is some milk in the glass.(改为否定句) There _________ _________ milk in the glass. (2005年四川省) 3)There _________ a knife and a fork on the table. (2005年黄冈市) [简析]第1)题中的“It is very easy”表明“第一课很容易”,原因当然是“生词不多”,故答案为B.第2)题的题干为肯定句,改为否定句时,应将is变为isn't,some变为any,故空白处应分别填isn't和any.第3)题根据题干和四个选项可知,该句是肯定句,又根据主谓语一致原则中的临近原则,谓语动词该用seems to be,故答案为A. 考点二:动词be与主语的一致关系 动词be的形式要和最靠近它的主语在数上保持一致;另外,还必须注意不可数名词用作主语时,动词be应用单数形式。 [试题精选] 1)图书馆前有许多小树。 There _________ many young trees in _________ of the library. (2005年长沙市) 2)-_________ there _________ for me in the bus? A. Is,a room B. Are,any room C. Are,rooms D. Is,any room (2005年漳州市) 3)-What's on the desk? -There _________ a dictionary11 and two notebooks on it. A. is B. have C. are D. has (2005年岳阳市) [简析]第1)题中的主语trees为可数名词复数形式,所以,第一空应填are;“在……前面”应用in front of…,所以,第二空应填front.第2)题的题干问的是“公共汽车是否还有空间”,room用作不可数名词时,可表示“空间”的意思,这样,第一空应填is,故答案为D.第3)题根据主谓语一致原则中的临近原则,谓语动词应为is,故答案为A. 考点三:“There be…”与have的区别 “There be…”句式和have均可表示“有”的意思,但用法有别。“There be…”表示“在某处有……”,意为“存在有”;而have却表示“某人/某物有……”,意为“某人/某物拥有……”。 [试题精选] 1)-There _________ a concert12 this evening. A. are going to be B. is going to be C. is going to have D. will have (2005年福州市) 2)There _________ a football game between Italy14 and Germany15 tomorrow morning. A. has B. is going to be C. will have D. has been (2005年武汉市) [简析]第1)题根据时间状语this evening的提示,动词be应用一般将来时的形式,故答案为B.第2)题根据时间状语tomorrow morning的提示,动词be应用一般将来时的形式,故答案为B. 考点四:“There be…”句式的反意疑问句 陈述部分为“There be…”句式的反意疑问句,简短问句由“be的适当形式+ there”构成。需要注意的是陈述部分中是否有seldom,hardly,little,few,no,nothing,nobody之类的否定词或半否定词。若有,该部分应看作否定意义,简短问句部分则用肯定式;如果陈述部分含有表示否定意义前缀的单词,该部分仍应看作肯定意义,简短问句部分要用否定形式。例如: There is nothing in the box,is there? There was an unusual16 bike under the tree,wasn't there? [试题精选] 1)There is some water in that bottle,isn't _________? A. there B. it C. that D. this (2005年武汉市) 2)There is little milk in the bottle.(变为反意疑问句)(2005年桂林市) There is little milk in the bottle,_________ _________? [简析]第1)题的陈述部分为“There be…”句式的肯定形式,简短问句部分应用否定形式,空白处应填there,故答案为A.第2)题的陈述部分含有表示否定意义的单词little,因此,该部分应视为否定形式,简短问句部分应用肯定形式,空白处应填is和there. [巩固练习] 1. Look! There _________ some apples on that tree.
