【答案与解析】
1. passing。have a hard time (in) doing做某事有困难,介词in可以省略。故答案是passing。
2. watching。spend…(in) doing花费时间做某事,介词in可以省略。故答案是watching。
3. raising。have trouble (in) doing做某事有困难,介词in可以省略。故答案是raising。
4. talking。句意:尽管他们知道我不会说葡萄牙语,但这并没有阻止他们与我交谈,我们能够毫无问题地交流。分析句子结构,空处作非谓语动词,用于介词from之后,应用动名词形式作宾语,stop sb. from doing sth.“阻止某人做某事”。故填talking。
5.being polluted。prevent sb. from doing sth.“阻止某人做某事”,同时又是被动含义。故填being polluted。
