文章讲解

When you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the B.B.C. If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down!

知识点:

虚拟语气（定义、分类、结构）

对过去的虚拟：If + 过去完成式，would/could/should/might have done.

翻译：如果20年前在北京买几套房子，我现在就是亿万富翁了。
表达：If I had bought a few houses/apartments in Beijing 20 years ago, I would have been a billionaire now.

翻译：如果皮特和他的初恋没有分手，他们现在的小孩差不多要5岁了。
表达：If Peter hadn’t broken up with his first love, their child would have been 5 years now, give or take.

真实条件句（和虚拟语气区别，结构）
结构：主将从现。
例句：If I work hard enough, I will be where I want to be.
例句：If I don’t find a part-time job, I won’t have enough money to pay my rent.

被动语态和是时态结合。

请造句——结合自己真实情况。你有什么后悔的，可以现在自己表达出来。

备注： of + 名词＝形容词（of immense size = extremely accurate）

介词短语做后置定语
结构：名词＋介词短语，相当于形容词修饰前面名词。
原句：Officials from Greenwich Observatory have the clock checked twice a day.

搭配： have something done 使某事被做
twice a day 一天两次（频率表达法）

5.On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower.
