下面我们继续本周《新概念英语2》第71课的重点句型或语法的分享。先来读一读课文：
一、课文原文
Lesson 71 A famous clock
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 hot 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!

本课主要是复习第60-69课的重点句型和语法：
（一）第60课
主要学习时间和条件状语从句中的“主将从现”的用法，即当整个句子基于现在时间来对将来的事情进行描述时，其时间或条件状语从句的谓语动词要采用一般现在时，而其主句都采用一般将来时。如：
If it rains tomorrow, we shall stay at home. 如果明天下雨，我们就待在家里。 As soon as the rain stops, we shall go out. 雨一停我们就要出去。
（二）第61课

'Open the door for me please,' she said to me. She told/asked me to open the door for her. 'Don't make so much noise,' she said to the children. She told/asked the children not to make so much noise.
