go→ going ask → asking look → looking（ 2）以不发音的 e 结尾的动词，去掉 e 加ing。

have → having take → taking make→ making write → writing（ 3）以一个辅音字母结尾的重读闭音节，双写最后一个字母，再加-ing 。

get → getting swim→ swimming begin → beginning shop→ shopping 4.现在进行时态的肯定式、否定式、疑问式及简略回答。

（ 1）肯定式：be＋v-ing She is singing in the next room.（ 2）否定式：be＋not＋v-ing The students aren ’t cleaning the room.（ 3）一般问句： be 动词提前。

2、结构： (1) There is +单数可数名词 /不可数名词 + 地点状语 .(2) There are +复数名词 +地点状语 .注意事项： there 是引导词，在句中不充当任何成分，翻译时也不必译出。

句子的主语是某人或某物，谓语动词 be 要与主语（某人或某物）的数保持一致。

当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。

如：There is a teacher and many students in our classroom.我们教室里有一位老师和许多学生。

There are many students and a teacher in our classroom.树下有两个男孩，一个女孩。

there be 句型的常考点考点一：各种句型转化。

1：变成否定There be be be notno 即可。

注意 not 和 no 的不同： not 是副词， no 为形容词， not a/an/any + n. 相当于no+ n.。

例如：There is a bike behind the tree. → There isn't a bike behind the tree. =There is no bike behind the tree.2：变成一般疑问句There be 句型的一般疑问句变化是把be 动词调整到句首，再在句尾加上问号即可。
