【小题4】Several articles about memory were written by Jane last month. (改为主动语态)

【小题5】“Can you help me repair the bike?” Mary asked Jack. (改为间接引语)
Mary asked Jack he help her repair the bike. Did, use
网友回答
(答案→)Did, use
解析：
【小题1】考察一般疑问句.短语used to do sth过去常常做某事,used相当于过去式行为动词,故一般疑问句要用助动词did.同时注意将行为动词变为原形.填:Did, use
【小题2】根据划线部分内容,可知下文对原因进行提问,故疑问词用why,结合语境可知上文描述的是过去动作,故助动词用did,填:Why, did
【小题3】unless除非,如果不,or否则,注意这两个连词表示因果关系的不同.
【小题4】结合语境可知上文的宾语是Jane,故用作下文主语.上文为过去时态,故将上文过去分词written,改为过去式wrote,作为谓语动词.
【小题5】一般疑问句改为间接引语时,一般用if/ whether是否,做引导词,同时注意从句中的时态语主句保持一致.
