【答案】

【1】Neithernorhas

【2】sad enoughto

【3】 to cry

【4】Whydoes

【5】feel likestaying

【解析】

【1】句意：他和他的父母以前听说过这个计划。因为原句用的是现在完成时，both...and...连接的两个并列的主语，如果变成否定的含义，应该用否定连词Neither...nor ，谓语动词用肯定的形式。

【2】句意：这个音乐如此地让人伤心以至于它使我想要离开。so...that当that后的句子的主语与主句的主语同一个时，可以与形容词或副词+enough+to do的形式来互换。

【3】句意：大声的音乐使婴儿哭了。短语make sb do sth使某人做某事；被动形式为sb be made to do ，这里baby与make之间是被动关系。在主动语态中用省略to的动 词不定式作宾补，但在其被动语态中，不要省略动词不定式符号to。

【4】句意：他因为丢了自行车看起来很伤心。因为划线的表示的是原因，所以应该用疑问词why来问。原句的动词是look，所以应该用助动词来帮助构成疑问句。

【5】句意：在周末我想和我的父母呆在家里。want to do sth=would like to do sth=feel like doing sth喜欢做某事。
