?肯定句:主语+am/is/are+V-ing+其它.

Iamnotreadingabookinthelibrary.

?否定句：直接在am/is/are后加not.;一般疑问句及回答:

—Areyoureadingabookinthelibrary?

—Yes,Iam./No,I’mnot.

直接把am/is/are提句首,若原句有第一人称，把第一人称变成第二人称。

肯定回答:Yes,主语+be(be是要变化的，即am/is/are).

否定回答:No,主语+be+not.

特殊疑问句：

格式为：What+am/is/are+主语+doing?;时间状语;Wedonotusuallyusetheverbsintheboxbelowinthepresentcontinuoustense.Instead,weusetheminthesimplepresenttense.有些动词通常不可用于现在进行时态,而用一般现在时。

;现在进行时VS一般现在时

现在进行时：强调此刻或现阶段正在进行的动作，

一般现在时：强调动作的经常和反复，或属于主语本身具有的特征，实际上这类动作没有时间性。

eg.: Jenniferisreadingabooknow. Jenniferreadsbookseverynight.

;瞬间动词的用法

一般说来，瞬间动词不能用现在进行时表达，但是像come，go，leave,arrive，start，fly等瞬间动词用现在进行时表达时常与表示将来时的时间状语连用，表示将要发生的动作。

例如:TheyareleavingforAustraliatomorrow.

;areeating;iseating;;1.Sheiswatchingaballet.(变否定句)

2.We’rewaitingforourteacher.(变一般疑问句);

Pleasebequiet.Thekids____________(sleep)now.
