例：1 Does Jenny has (has) a good friend?

　　 2 Brian doesn’t lives (not live) in China.

答案：1 Does　 have　　 2 doesn’t live

解析：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didn't go home yesterday.

例：1 He plaies (play) football very well.

　　 2 Danny gos (go) to school at 7:10.

答案：1 plays　 2 goes

解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2与名词变复数不同，变单三人称形式以o结尾的词要加es.

1 Jenny ____ in an office.　 Her parents ____in a hospital.

A work; works　　 B works; work　 C　 work; are working　 D　 is working; work

2 One of the boys_____ a black hat.

A have　 B there is　 C there are　 D has

3 We will go shopping if it____ tomorrow.

A don't rain　 Bdidn't rain　 Cdoesn't rain　 Disn't rain

4 He said the sun ____in the east and ____in the west.

A rose; set　 B rises; sets　 C rises, set　 D rise; sets

5 Wang Mei ____ music and often ____ to music.

A like; listen　　 B likes; listens　　 C like; are listening　　 D liking ; listen

6 Jenny____ English every evening.

A has study　 B studies　 C study　 D studied

答案：1 B　 2D　 3C　 4B　 5B　 6B

例：We are plant　 (plant) the trees in spring.

答案：plant

解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”

专项练习：

2、Li Mingisn’t read ( not read) a book in bed now.

答案：1 are flying　 2 isn’t reading

解析:现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。

三 对动词或动词词组提问时丢掉doing

例：1 、The students are singing in the room.(对划线部分提问)

　　　　 What are the students in the room?

答案：What are the students doing in the room?

解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”

或简写为“What......doing......”?句式。

四 现在进行时态的选择疑问句中易忽视or后用现在分词形式

例：孩子们在跑还是在跳？

　　 Are the children running or jump?

答案：Are the children running or jumping?

解析: or连接的是两个并列成分，动词形式须一致。

2、Jenny is plaiing(play)football.

答案：1.swimming　　　 2 .playing

解析：动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开。

二 丢掉be动词或忘记把动词变成现在分词

例：1、 Look, two children flying.(fly) a kite in the park.

7、The girl____(like)wearing a sweater. Look! She ____(wear)a red sweater today.

答案：1 is lying　 2 is mending　 3 are playing　 4 are doing

　5 Is cleaning　 6 is singing　 7 likes ;　 is wearing

一　 把动词变成现在分词形式易出错

例：1、They are swiming.(swim)

6、 Who____(sing)in the next room?

5、 ____he ___(clean) the classroom?

4、 What ____you____(do) these days?
