A.stayed B.had stayed C.was staying D.have been stayed （请各位指教，尽量说些理由。）

Answer 1

1.d
explain
是动词，后面加宾语，备选答案中，只有d可以做explain的宾语
2.b更佳
理由说不上，个人认为其他的选项语法上都没有错，也可以回答这个问题
3.a（我也不知道对不对了，等高手吧）

Answer 2

1.
c
,因为only加短语或句子放在句子开头时，要倒装，而且d的倒装是错的，be后面要用形容词2.
a，因为这个句子是强调句，陈述句语序是:it
was
then
that.........,
然后根据意思：那时所有的普通人都毫不费力地掌握了，那怎么样呢？所以选a。
