“If no surplus is available,a farmer cannot be 47.He must either sell some of his property or (48 seek)extra funds in form of loans.Naturally he will try to borrow money at a low (49 rate)of interest,but loans of this kind are not 50 obtainable.”
分析:本题处在一个总述句中:If no surplus is available,a farmer cannot be 47.在此句话之前,文章都是在讲If surplus is available(有赢余的情况下),农民的生活如何;实际上,从文章结构来看,从本题开始出现了另一个意群,而If no surplus is available,a farmer cannot be 47为这个意群的总述句,即如果没有赢余,农民会怎样?
总结一下分述部分很容易判断出47题的答案一定是[B]self-sufficient,因为总述句中的not be self-sufficient恰恰是对分述的最佳概括。

下一句- 41(答案:Neither) kind of sleep is at all well-understood(两种睡眠都没有被很好地理解),这就是文章的基本导向。
