1、sat语法题

Traffic was heavy, so by the time B finally arrived at the theater, we 【waited】 for her for an hour, missing the entire first act of the play.

请问：为什么括号里的要改成had been waiting？因为by the time吗？是不是只要看到by the time都用过去完成时呢？

谢谢。

2、sat的一道语法题目

In 1850 Jim Beckwourht, a Black American explorer, (discovered) (in the) mountains of the Sierra Nevada a pass (soon becoming) an important (gateway to) California gold-rush country.NO error 答案是C，为什么soon becoming 不对而要改成which soon became呢？

3、三道SAT的语法题

(He discoveres, too late, that it would have been) more worth his while to have worked for the mining company than for the telecommunications company.答案就是这句话的原句，为什么不能写成He discovered, too late, that is had been？

A number of companies are adopting flexible working hour policies, (something many experts say will benefit both companies and workers.) 答案还是原句，为什么不能写成something, according to experts, that will b enefit both companies and workers?

One of the most demanding pursuits in the world, world class tournament chess (has even more demands, more preparation and mental stamina than fields such as) organic chemistry.答案是is even more demanding, requiring more preparation and mental stamina, than fields such as，那原句又错在哪儿？书上说原句的错误是“an idiom error”....
