答案

小题1:are looked
小题2:certain
小题3:to decide
小题4:knives
小题5:were chatting

解析

小题1:考查被动语态。所有的无家可归的孩子都得到了很好地照顾。主语是动作的承受者，故用被动语态。故填are looked。
小题2:考查形容词作表语。am是系动词，后跟形容词作表语。故填certain。
小题3:考查固定句型。It is+形容词+to do sth“做某事怎么样”。故填to decide。
小题4:考查名词的复数。以f或fe结尾的可数名词，要变f或fe为ves。故填knives。
小题5:考查时态。根据句意可知，应该用过去进行时。故填were chatting。
