二.现在进行时的谓语结构:

现在进行时的谓语结构为:am/is/are +现在分词.Am/is/are 在现在进行时句子谓语结构中作助动词用，无词义。Am/is/are的选择运用由句子的主语人称或数决定。

四.现在进行时的形式转换：

1.将一个现在进行时的肯定句变为一般疑问句时，将句中的is或are提到句首。

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.

(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).
