答案及解析：

1.B【解析】介词(in)的后面应当使用名词形式。A 选项和B 选项都有可能，但考虑到空格中应该填入充当宾语的名词，此处应填入主动语态。A 选项是被动语态，是错误的。

2.D【解析】be 动词的后面使用“形容词+介词”形式，往往考查的是固定搭配。be responsible for…对某事负责。

3.D【解析】将其当作“be+形容词”的固定搭配来记忆。be concerned about sth.意为“关心某事，记挂某事”。

4.C【解析】因为句子中没有谓语动词。所以排除D 选项。考虑到单复数的问题。排除A 选项。后面有宾语，所以排除被动语态B选项。

5.B【解析】be 动词后面的动词应使用过去分词，也就是形容词的形式，空格后有to，所以应当考虑固定搭配。attribute A to B(=A is attributed to B)把A归因于B(题目意在考查固定搭配的被动语态用法)。
