_____we promise continuous increase in rural incomes _____improve the whole people's well-being.
A.Only if; we can
B.If only; can we
C.Only if; can we
D.Unless; we can
答案:C
题目分析:句意:只有我们承诺不断地增加农村地区人们的收入,我们才能够提高整个人们的幸福感。Only if只有,位于句首时主句要部分倒装。If only要是…该多好啊!故选C.
点评:only所修饰的副词、介词短语或状语从句位于句首时,要用倒装语序。如:Only then did I realize the importance of health.到那时我才认识到健康的重要性。注意:only修饰主语时,句子不需要倒装。Only he knows the truth.只有他知道真相。
