1. D这是一个含蓄虚拟句，意为“有些妇女完全可以不呆在家里，干一份工作挣得可观的工资，可是她们决定不工作，为的是照顾家庭”，所以选D。should have made意思是“本应该做而实际上没做”，与原句意不够贴切。

2. B相当于A light with no more power than the power that is produced by…。that代替power，表示相比较的事物，而D中没有比较对象，故不对;as表示原级比较，不与than用在一起，故A也不正确;C中缺少that的先行词，也是错误的。

3. Clet alone，“更不用说……”，在用法上相当于并列连词，因此要求填入与前面一样的结构，此处是不定式。

4. D句子要求填一个能够代替these refrigerators 的代词，故排除A、C。the others一般与另一部分相对而言，在此句中不对，所以选the ones。

5. A句子后半句是倒装句，主语是复数its soil and the water of its lakes, rivers and oceans，因为较长，所以后置，故选A。
