11页Unit 3: 本单元的重点语法I.there be句型的时态:一般现在时: there is / there are一般将来时有 there will be 和 there is going to be 两种形式注意:句中的be不能说成have,这是学生们最容易出错的地方一般过去时有 there was 和 there were 两种形式2 .there be句型表否定含义的另一种形式:可用“no来表示即:no +名词注意: no 可以 + 可数名词单数There is no book on the desk.no 可以 + 可数名词复数There are no books on the desk.no 也可以 +不可数名词There is no juice in the bottle.3 .不定代词在 there be 句型中的用法不定代词在句中作主语,谓语动词要用单数形式例如: There is nothing in the fridge. 冰箱里什么都没有4 .There be 句型的反意疑问句,要注意陈述部分的形式如果陈述部分含有 little , few , no , nobody , none 等否定词时,后面的简短问句中要用肯定形式。
例如: There is nobody in the room , is there ?房间没人,对吗?但有的含有否定意义的形容词修饰时则仍看做肯定句式例如: There is something unusual in the room , isn't there ?5 .there be 句型与情态动词连用表推测,例如: There must be a book on the desk. 在桌子上肯定有一本书6 .我们书中出现了: there be +主语 + 不定式 / 现在分词 / 过去分词的句式,后面的部分都是起到修饰前面名词的定语作用课文原句有:? 1.There are many interesting places to visit.? 2.There are many food stalls selling all kinds of food.? 3.There are thousands of warriors and horses buried in the grave of the first Chinese Emperor.注意:动词不定式作定语时,如果是不及物动词, 且与所修饰的词之间有动宾关系,要在不定式后加上适当的介词 .如: There ’ s nothing to worry about. 没什么可担心的。
7 .there be句型是表示存在的一个句型,是一个主语在be动词后面的倒装句这 种句式也可表达为:地点 +be +名词的形式例如: There ’ s a baknon the main street相当于 On the main street is a bank.8 .副词开头的倒装句:在以 here , there, out, in, down, away 等表示方位的副词开头的句子中,如果主语是名词,要用倒装句因此,谓语动词的形式由位于倒装句句尾的主语决定如: There goes the bell. 铃响了Here are some flowers. 这里有一些花注意:如果主语是人称代词,就不必倒装Here you are. Here it is.第三单元和 Fun Time 的语言点:1 .hairdresser 有两个含义一是理发师,二是理发店理发店的另一种说法:hairdresser ’ s.如: A hairdresser or a hairdresser's is a shop where a hairdresser works. 理发店是理发师工作的地方2 . crowd:n. 人群; 群众; 一群如: a crowd of lookers-on 一群围观的人v. 拥挤,聚集如: The children crowded around the TV . 孩子们聚集在电视周围。
