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。 (责任编辑：admin) |
