, at present , these days 5、现在分词的构成规则：

1.一般情况下，直接加ing，如：cook-cooking、read-reading、look-looking、listen-listening 2、以不发音的e结尾，去e加ing，如：make-making, have-having、write-writing、

skate-skating、smile-smiling、make-making、taste-tasting、close-closing 3、如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing，如：run-running, stop-stopping、get-getting、swim-swimming、sit-sitting、begin-beginning 4、以ie结尾的动词，要把ie变成y再加ing，如die→dying，lie→lying、tie-tying 否定式

I am not working. You are not working. He/She is not working. We/You/They are not working. Step2. Consolidation 1.写出下列动词的现在分词形式

have、talk、write、smile、sit、put、swim、listen、sleep、lie (2)Exercise(pair work): a.Get students to finish Exercise on page 50. Step 3: 现在进行时和一般现在时的区别

1、现在进行时表示现在进行的动作，一般现在时表示经常性的动作。

He is reading newspaper now.他现在正在看报纸

He reads newspaper every day.他每天看报纸

5、有些表示状态、感觉或情感的动词一般不用于进行时态，例如：

know, want , like , hear , hope , hate，look等。

He looks well.他今天气色不错（表状态）

I hate you.我讨厌你（表情感）

Step 4:Practice: Get Ss to finish exercise B on page 51. Do some related exercise on page 79-81 in book B. Step 5: Summary：Get students

to summarize what they have learned

today. 本节课内容小结: be 加动词

ing，直接、双写、去e，ie变y ing，别说

be 词无词义,主语和它最亲密; 变疑问

be 提前,否定

not 后添;何时要用进行时,look,listen,now 是标志。
