初中英語(yǔ)的變化技巧有哪些

　　一變：肯定句變?yōu)榉穸ň?/strong>

　　【技巧1】當(dāng)句中含有情態(tài)動(dòng)詞或助動(dòng)詞could，would，should等時(shí)，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 / couldnt get you a concert ticket。

　　【技巧2】當(dāng)句中含有系動(dòng)詞was，were 時(shí)，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 / wasnt on the Internet when you called me。

　　【技巧3】當(dāng)句中謂語(yǔ)是除情態(tài)動(dòng)詞、助動(dòng)詞、系動(dòng)詞was，were以外的動(dòng)詞時(shí)，在該動(dòng)詞之前加did not / didnt，動(dòng)詞還原，構(gòu)成否定句。例如：

　　The famous singer sang some Chinese songs。 The famous singer did not / didnt sing any Chinese songs。

　　二變：陳述句變?yōu)橐话阋蓡?wèn)句

　　【技巧1】移動(dòng)詞語(yǔ)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(dòng)詞did。謂語(yǔ)是除情態(tài)動(dòng)詞、助動(dòng)詞、系動(dòng)詞was，were以外的動(dòng)詞時(shí)，在主語(yǔ)之前加did，動(dòng)詞還原。例如：

　　三變：陳述句變?yōu)樘厥庖蓡?wèn)句

　　【技巧1】確定疑問(wèn)詞：人who / whom，物what，地點(diǎn)where，時(shí)間when / what time，原因why，頻率how often，長(zhǎng)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(rèn)結(jié)構(gòu)形式：疑問(wèn)詞+情態(tài)動(dòng)詞/助動(dòng)詞/ was / were / did +主語(yǔ)+。？ 例如：

　　The accident happened near the station。 Where did the accident happen
