【答案】
【1】has been busy working
【2】so poor that he had to
【3】It’s very necessary to know
【4】What were you doing
【5】It’s a good habit to help
【解析】
【1】根据后文的时间状语these days,表示最近持续在做的动作,应该用现在完成时have/has done;根据主语My mother为三单,可知用has;根据固定搭配,be busy doing意为“忙于做某事”,故填has been busy doing。
【2】根据句意,可知用so…that…引导结果状语从句;根据固定用法,have to do意为“不得不做某事”;根据前文主句用一般过去时,可知从句也用一般过去时,have的过去时为had,故填so poor that he had to。
【3】根据句意,可知用固定句型it’s+adj.+to do sth.,意为“做某事是……的”,it为形式主语,后文动词不定式为真正主语;故填It’s very necessary to know。
【4】根据时间状语at 8:00 pm yesterday,可知用过去进行时was/were doing;根据特殊疑问句结构为:特殊疑问词+助动词/情态动词/be动词+主语+句子其他成分,根据主语为you,可知be动词用were,故填What were you doing。
【5】根据句意,可知用固定句型it’s+n. +to do sth.,意为“做某事是……” it为形式主语,后文动词不定式为真正主语;故填It’s a good habit to help。
