35 Orchid seeds take up to eighteen months to mature before they sprout, and the young plants may need another two years to reach at the flowering stage.
这道题答案是给的D,认为没有这种搭配,我认为是A,take up some time是不能有to的,我查了一下金山糍粑,好像也支持我的说法,希望大牛能给一个解释
36 The oldest public edifice in Washington D.C, the White House was originally constructed in the 1790`s, also has been rebuilt or extensively remodeled three times since.
这到底答案给的是C,认为also改成and,但是为什么D选项since后面没有then呢?
谢谢~
