1、把動詞變成現在分詞形式易出錯。例:
(1)誤:They are swiming (swim) .
正:They are swimming (swim).
(2)誤:Jenny is plaiing (play) football.
正:Jenny is playing (play) football.
解析:A、動詞變現在分詞可有如下口訣:一般-ing;啞e先去e;重閉單輔先雙寫;-ie結尾y來替。
B、動詞現在分詞的變化規則要與名詞變復數、動詞變現單三等規則區分開來。
2、謂語部分的構成不完整:丟掉be動詞,或忘記把動詞變成現在分詞。例:
(1)誤:Look! Two children flying (fly) a kite in the park.
正:Look!Two children are flying (fly) a kite in the park.
(2)誤: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:現在進行時的謂語部分的構成是"be+現在分詞",二者缺一不可,這一點必須要牢記。
3、對動詞或動詞詞組提問時,丟掉代動詞doing。例:
The students are singing in the room.(對劃線部分提問)
→誤:What are the students in the room?
→正:What are the students doing in the room?
解析:現在進行時態中對動作提問可記住此句式"What +be +主語+doing+其它?"或簡寫為"What......doing......? "句式。
4、現在進行時態的謂語部分是并列結構時,容易忽視第二個以及第二個以后的動詞用現在分詞形式。例:
孩子們在跑還是在跳?
誤:Are the children running or jump?
正:Are the children running or jumping?
解析: or連接的是兩個并列成分,動詞形式須一致。
