Answer 1

【答案】
（1）in；order；to
（2）looking；after
（3）Does；need
（4）don't；have
（5）It's；sad
【解析】 (1)in orderto so that与in order to 同义，都有“为了”之意。但so that后接从句，in order to后接动词原形。
(2)looking after take care of与look after同义，均意为“照顾”。
(3)Does; need needs为动词的第三人称单数形式，且后跟动词不定式，由此可判断need在此作实义动词，且该句是一般现在时态。主语是第三人称单数，变一般疑问句需借助于助动词does，后接动词原形。
(4)don't have 主语为复数，谓语动词为行为动词，变否定句时，要借助助动词do的形式，do not可缩写成don't，后接动词原形。
(5)It's sad 用it作形式主语，动词不定式作真正的主语。
