Answer 1

分析 1）Did they go to the library？
2）I don't want you to go to your room at once．
3）isn't it
4）How long have you had to stay there？
5）He says that he comes from Australia．

解答 1）答案是Did he have to go to the library？本題考查句型轉換；題目要求改成一般疑問句；原句是含有have to 的肯定陳述句，改一般疑問句時要在句首加助動詞do的適當形式；原句是過去時，故在句首加did，had to 還原為have to；故答案是Did he have to go to the library？
2）答案是I don't want you to go to your room at once．本題考查句型轉換；題目要求改成否定句；原句是含有實意動詞want的肯定陳述句，改為否定句時要在實意動詞前加助動詞do not的適當形式；本題是一般現在時，故在want前加don't，故答案是I don't want you to go to your room at once．
3）答案是isn't it；本題考查句型轉換；題目要求完成反意疑問句；反意疑問句的疑問句部分的結構是"助動詞+主語？"，助動詞和主語與陳述句保持一致，并且遵循"前肯后否"或"前否后肯"的形式；本題中前面的陳述句是肯定句，故疑問句用否定，陳述句中助動詞為be，主語the handbag用it代替，故答案是isn't it．
4）答案是How long have you had to stay there？本題考查句型轉換；題目要求就劃線部分提問；被劃線的是段時間"for a week"，所以用how long 提問；將原句中的助動詞have提到主語之前構成一般疑問句，并將第一人稱改為第二人稱，故答案是How long have you had to stay there？
5）答案是He says that he comes from Australia．本題考查句型轉換；題目要求改為間接引語；直接引語改為間接引語時，原句是陳述句，改為that引導的賓語從句；主句動詞是一般現在時，原直接引語中的時態不做變化，主語改成與主句主語一致，故從句中動詞用第三人稱單數，故答案是He says that he comes from Australia．

點評 本題考查句型轉換，在比較原句和改寫句的基礎上分析同義結構或句型，要積累常見同義詞、同義短語和同義結構．
