题目内容
Measures must be taken to prevent pollution ________ happily.
| A．from we live | B．for us to live | C．us living | D．from our living |
B
解析试题分析：考查句意：对于我们来说，为了幸福地生活着，我们必须采取一些措施阻止污染。for us对于我们来说，to live不定式表示目的，本题中注意采取措施做某事的句型take measures to do sth,而prevent sb from doing sth阻止某人做某事，不符合题意，而只能用不定式作为目的状语才符合题意，不定式的逻辑主语是us。故选B
考点：考查不定式做目的状语
