Eg: Steve is talking to his teacher.----------Is Steve talking to his teacher?
I am singing.--------- Are you singing?2.将现在进行的肯定句变为否定句时，在be动词后面加上not. Eg: Steve is talking to his teacher
-------Steve isn’t talking to his teacher.
The children are eating some apples at my home.
---------The children aren’t eating any apples at my home.
五.现在进行时的判断：（1）一般句中用到表示“在现在”的时间状语，如：now, right now, at the moment 或It’s+几点钟”句型，常判断用现在进行时。Eg:
Let’s go fast .Mr. Wu is waiting for us now.
It’s six o’clock.The children are playing basketball.
(2)句中用到“Listen！” “Look!” “Keep quiet” “Don’t make noise!”等提示语时，表明说话间另一个动作正在进行，这时，句子也要用现在进行时。Eg:Keep quiet !
The teachers are talking in the office. (3)现在进行时常用来表示在当前一直做着的动词，这时句中常用these days ,all the time等时间状语。Eg: These days,uncle Wang is building a small room for his dog.(4)通过上下文句义，表明某一动作是现在或说话瞬间发生的动作，这个句子也要用现在进行时态。Eg:
———Is your mother at home?
———Yes, she is .she is watching Tv .
———Where is Tom?
———He is running on the playground .（5）.表示状态和感觉的词，一般不能用于进行时态，因为他们不能表示正在进行的动作。Eg:
Look! There are some sheep on the hill.
Look! The boat looks like a duck.
Now ,I want to go to Beijing.（6）.对于无法持续动作的词，一般常用现在进行时表示将来。如：
Go come leave start arrive move 等。
Eg:We are leaving on Friday.
I’m coming.Exercises:根据句意，用所给动词的适当形式填空：（1）Listen, Mr. Wu on the phone (talk).
(2) I soccer now.I’m walking (not play)
(3) ——Is your father at home?
——Yes ,he is .He a TV show (watch)
(4)They to go to the shop now. (want )
(5)— you for your friends? (wait)
