1．A decade ago,there were only ten factories in my hometown , but ___the number increased twice。 A。 at the same time B 。
at present 答案选B。题解：一般过去时用于表达说话时该动作已经发生了，而一般现在时表达该动作经常或反复发生，不能一看见at present 就用一般现在时。 2。The baby is due in November ,by ____the new house should be finished 。
A。 where B。 which C。 when D。 that 答案选C。题解：小孩将在11月降生，到那时新房子也该修好了。the new house should be finished 。是修饰November 的定语从句，将其还原就是the new house should be finished by November ,因为by November 是时间状语就用引导词when了，by可以放在引导词前面。
