  1、把动词变成现在分词形式易出错。例:  (1)误:They are swiming (swim) .  正:They are swimming (swim).  (2)误:Jenny is plaiing (play) football.  正:Jenny is playing (play) football.  解析:A、动词变现在分词可有如下口诀:一般-ing;哑e先去e;重闭单辅先双写;-ie结尾y来替。  B、动词现在分词的变化规则要与名词变复数、动词变现单三等规则区分开来。  2、谓语部分的构成不完整:丢掉be动词,或忘记把动词变成现在分词。例:  (1)误:Look! Two children flying (fly) a kite in the park.  正:Look!Two children are flying (fly) a kite in the park.  (2)误:Li Ming isn't read ( not read) a book in bed now.  正:Li Ming isn't reading ( not read) a book in bed now.  解析:现在进行时的谓语部分的构成是"be+现在分词",二者缺一不可,这一点必须要牢记。  3、对动词或动词词组提问时,丢掉代动词doing。例:  The students are singing in the room.(对划线部分提问)  →误:What are the students in the room?  →正: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。  4、现在进行时态的谓语部分是并列结构时,容易忽视第二个以及第二个以后的动词用现在分词形式。例:  孩子们在跑还是在跳?  误:Are the children running or jump?  正: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。
