There be 句型有特点,主语放在 be 后面?单数主语用 is,复数用 are 记心间?变否定,很简单,be 后要把 not 添?肯定句中用 some, 否定,疑问 any 换 。如: go boating(fishing,hunting,shootiing,biking,walking Sailing ,riding,skiing,autoing,camping) 等 ,这类词不多,如: go shopping(marketing,windowshopping, Sight-) 等 ,但并不是凡讲职业都用这种结构的,实际上很有限。如: go farming(soldiering,nursing) 备注:动词- ing 形式的构成:是在动词末尾加 ing 形式构成,因此又叫动词的- ing 形式。否定形式: not+ing 构成。从语义上, go doing 大约可分为 There be 句型的一般疑问句中 be 动词的单复数(单数 is; 复数 are; 不可数的用 is) 一般疑问句: be 动词(is,are) 要提到句首;some 变 any ,其他都不变 There is a mouse in the house.( 变成一般疑问句) Is there a mouse in the house ?

There are some …→ Are there any …? 肯定回答: Yes, there are. 否定回答: No, there aren ’ t. some 和 any 的区别 some 和 any 既可以修饰可数名词又可以修饰不可数名词, some 常用在肯定句中,而 any 则常用在否定和疑问句中。因此 some 和 any 的用法主要是考虑用在肯定句、疑问句还是否定句中,与名词的可数与否无关。 some 意为“一些”,可作形容词和代词。它常修饰可数名词复数。如: some books 一些书, some boys 一些男孩,也可修饰不可数名词,如: some water 一些水, some tea 一些茶叶, some 常用在肯定句中。 any 意为“任何一些”,它也可修饰可数名词复数或不可数名词,常用于疑问句和否定句。疑问句: Are there any lakes on the mountain? 在山上有湖吗? 肯定句: There are some lakes on the mountain. 在山上有湖例:
