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。

A light with no more power than ________ by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam.
A.circled
B.to circle
C.circling
D.circles
C 句子的主语为solar power or fission power， 谓语是may give, collected by satellite circling the earth是后置定语修饰solar power，其中circling the earth 又是现在分 词短语修饰satellite，“环绕地球的卫星”， 相当于the satellite which circles the earth。 其他选择项均不符合句子语法结构要求。
A. as is produced
B. that produced
C. that is produced D. produced

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。

A.only if B.that there had only been C. that had there only been D. if there were only
C 这是一个so…that结构表示结果状语的句型， A、D 可以排除。在that从句中又有条件从 句，而且应该是虚拟语气结构，B中没有表 示条件的连词，是错误的。C虽然也没有连 词if，但采用了倒装结构，可以将if省略， 又是had done，表示与过去事实相反的假 设，时态、结构完全正确，因此是惟一正 确的选择。

A
For these children to develop to their full adult potential在句中做目的状语，these children 是to develop 的逻辑主语，这种主 谓关系在目的状语中一般是不能用分词表 示的。B中不定式被动式与句意相悖;for不 是连词，故不能选D，否则语句不通。
