以下是引用Apricot在2004-9-8 11:04:00的发言：

11.         over 100 years since the invention of the square-bottomed paper bag. D

(A)  Now is

(B)  Now it has

(C)  There is now

(D)  It is now

为什么选D呢 记得老师说过好像只有强调句式开头的话用It is

这里就是一个强调句，it is-----that/who/since-----.

35.  Orchid seeds take up to eighteen months to mature before they sprout, and the

A                            B

young plants may need another two years to reach at the flowering stage.

C                       D

答案D 是介词问题吗？ 不应该用at？

reach 是及物动词，直接加宾语就可以，去掉at

36.  The oldest public edifice in Washington D.C., the White House was originally

A                                                   B

constructed in the 1790's, also has been rebuilt or extensively remodeled

C   

three times since.

D  

答案C 不明白

这里一个句子出现了两个谓语且中间没有连词，改成 and also，and 做连词

1、        over 100 years since the invention of the square-bottomed paper bag. D

(A)  Now is

(B)  Now it has

(C)  There is now

(D)  It is now

不是强调句，但可以作为固定用法记。

没有这个知识点印象的解题思路如下：

本句缺主语和谓语，用排除法看四个选项：A缺主语。B谓语不全。C,there be句型，表存在。剩最后一个选项D。

D项，主谓全。it做主语（除形式主语外）通常用来表示时间，天气等等。句意也没问题。因此选D。
