注意:
把動詞變成現(xiàn)在分詞形式易出錯
例:1、They are swiming.(swim)
2 、Jenny is plaiing(play)football.
答案:1.swimming 2 .playing
丟掉be動詞或忘記把動詞變成現(xiàn)在分詞
例:1、 Look,two children flying.(fly) a kite in the park.
2 、Li Mingisn’t read ( not read) a book in bed now.
答案:1 are flying 2 isn’t reading
解析:現(xiàn)在進行時肯定句的結(jié)構(gòu)規(guī)律為: “be+現(xiàn)在分詞,缺一不可”。這一點必須牢記。
對動詞或動詞詞組提問時丟掉doing
例:1 、The students are singing in the room.(對劃線部分提問)
What are the students in the room?答案:What are the students doing in the room?
解析:現(xiàn)在進行時態(tài)中對動作提問可記住此句式“What +be +主語+doing+其它?”
現(xiàn)在進行時態(tài)的選擇疑問句中易忽視or后用現(xiàn)在分詞形式
例:孩子們在跑還是在跳?
Are the children running or jump?答案: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。
