              答案：B。根据以上结构应排出其它项，选B。

11Pieces of the palaces that had been hidden before the Nazis came could now be used to rebuild the city and its culture.在法西斯来之前被藏起来的宫殿残迹现在可以被用来重建这座城市以及它的文化。 

［问］请问这个句子怎么理解？

［答］这是一个多重复合句，定语从句that had been hidden …came 修饰the palace，而定语从句中又含有一个时间状语从句before the n azis came.

 be used to是被动结构形式“被用于”

短语辨析：used to  过去常常，过去曾经

例如：He used to be a thief.

名题精选：My hometown is not what it ____.

A. was used to be B、used to be

C. is used to be D.has used to be

答案：B。“be used to do ”是“被用于”，而根据题意应是“家乡不再是过去的样子”，所以应选B。

12It was difficult to save the palaces and buildings without destroying their old beauty.挽救这些宫殿以及其他建筑而又不破坏它们原有的风格却不容易。

［问］句中不定式是什么用法？

［答］这是一个动词不定式作主语的句子。在日常英语中，特别是当主语较长而谓语较短时，常用it作形式主语，而将动词不定式放在谓语部分后边。本句中it是形式主语，后边to save the palaces and…old beauty是真正的主语。

例如：It is human to want something better.精益求精是人的特性。

名题精选：Is _____ necessary to complete the design before National Day?（89年高考题）

A. this B.that C.it D.he

答案：C。真正的主语是不定式“to complete…”，全句为“主系表”结构，要填的是形式主语。只有it才能作形式主语或形式宾语。

13With the help of old paintings and photographs,the people of St Petersburg were able to bring back the beauty of their culture and history.由于一些旧的油画和照片，圣彼得堡人能够重现历史和文化的原貌。

［问］can与be able to有什么区别？

［答］With the help of = with one’s help  在(某人)的帮助下

        Be able to 能够

 短语辨析：can 与be able to

 be able to 表示成功地完成某一具体动作，尤其表示克服某种困难与障碍后达到某种后果

 例如：In the end they were able to rescue the cat on the roof.

他们终于把猫从屋顶上救了下来。

名题精选：The fire spread through the hotel very quickly but everyone _____ get out .（97年高考题）

A. had toB.would C.couldD. was able to

答案：D。“was（或were）able to”相当于“managed to do”或“succeeded in doing”，强调过去动作的结果，表示成功地完成某一具体动作：“大家都设法逃了出去”，故选D。而“had to（不得不）”、“would（将会）”、“could（有可能）”都不合题意。

14I think one way to solve the problem is to put glass walls in front of the paintings. 我认为一种解决问题的办法可以在壁画前装上玻璃窗。

［问］solve有哪些意思？

a new way of solving differential equations

解微分方程的一种新方法。

15Can you think of other words that have more than one meaning?你还知道有哪能些多义词呢？

［问］think of有哪些意思？
