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。”

　解析：一般过去时表示过去发生的动作或存在的状态。 而过去完成时主要体现过去发生的两动作先后有别，即比过去发生的某动作还要“过去”，两动作中先发生的是过去完成时，后发生的则只用一般过去时。

专项练习：

　例：He asked what I have (have) said.

　 答案：had

　解析：现在完成时强调对现在的影响或结果．而过去完成时强调对过去的影响或结果．

　例：He hads (have) gone home when I got to his office.

　 答案：had

　解析：have/has 的过去式都为had, had 在过去完成时中也是助动词, 不能再有单三人称的变化.

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.
