一般過去時三種變化技巧
一變:肯定句變?yōu)榉穸ň?/p>
【技巧1】當(dāng)句中含有情態(tài)動詞或助動詞could,would,should等時,可直接在其后面加not構(gòu)成否定句。
例如:I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
【技巧2】當(dāng)句中含有系動詞was,were 時,可直接在其后加not構(gòu)成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
【技巧3】當(dāng)句中謂語是除情態(tài)動詞、助動詞、系動詞was,were以外的動詞時,在該動詞之前加did not / didn't,動詞還原,構(gòu)成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
二變:陳述句變?yōu)橐话阋蓡柧?/p>
【技巧1】移動詞語的位置。將was,were,could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
【技巧2】添加助動詞did。謂語是除情態(tài)動詞、助動詞、系動詞was,were以外的動詞時,在主語之前加did,動詞還原。例如:
Mr Li looked very old. → Did Mr Li look very old?
三變:陳述句變?yōu)樘厥庖蓡柧?/p>
【技巧1】確定疑問詞:人who / whom,物what,地點where,時間when / what time,原因why,頻率how often,長度how long,距離how far等等。例如:
They gave the concert last night. → When did they give the concert?
【技巧2】辨認結(jié)構(gòu)形式:疑問詞+情態(tài)動詞/助動詞/ was / were / did +主語+...? 例如
The accident happened near the station. → Where did the accident happen.
