下面我们继续本周《新概念英语2》第48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 48 Did you want to tell me something?
Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton wool. He knew I collected match boxes and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.

本课主要复习第26-45课难点部分内容，主要是常用的各类词汇及辨析、引号的用法、表示“一……就……”的句型，结果状语从句，定语从句以及时间状语等。
下面我们就通过一些例句来进行复习，如课文中出现的：
The new school, (who) (which) has just been completed, is a fine building.(28)
He (denied) (refused) that he had taken it. (29)
A bird flew (past) (passed) my window.(33)
The one with the money got such a fright that he dropprd the bag. (35)
Ships (continously) (continuaslly) across the sea. (38)
The bank has been (stolen) (robbed). (45)
下面我们来重点回顾一下以下三个重点内容：
（一）结果状语从句
结果状语从句常由so… that 或 such…that引导两个句型，具体如下：
1、so...that
so + 形容词 / 副词 + that...
so +形容词 + a + 单数名词 +that..
so + many / few (+复数名词 ) + that...
so + much / little ( +不可数名词 ) + that...
2、such ... that
such ( + 形容词 ) + 复数可数名词 / 不可数名词 + that...
such + a +( 形容词 ) 单数可数名词 + that...
注意： “such + a +形容词 + 单数可数名词” 可以用 “so+ 形容词+ a +单数名词” 替换。
例如：
He was so tired that he could not wake up.
他是如此困乏，以致不能醒来。
She is such a lovely child that everybody loves her .
= She is so lovely a child that everybody loves her.
她是一个如此可爱的孩子，因而大家都喜欢她。
（二）定语从句
定语从句中关系代词的用法。常见的关系代词有that、which、who、whom、whose。
其中，that 的先行词可以是人或物， which的先行词是物，who 和 whom的先行词是人，whose 的先行词可以是人或物。
当关系代词在从句中充当宾语时，经常可以省略。
当关系代词在从句中充当主语或定语时，不能省略。
例如：
The man whom you met yesterday is an actor.
The man you met yesterday is an actor.
你昨天见到的那个人是一位演员。
The bright star which is shining above the roof is called Sirius.
在屋顶上空闪烁的那颗明亮的星星叫做天狼星。
（三）时间状语从句
时间状语从句常由when、until、since、before、after、no sooner…than...、hardly...when...等连用。其中，当no sooner或hardly提到句首时，会引起倒装。hardly经常可以替换为scarcely、nearly、rarely等。
例如：
Dentists always ask questions when it is impossible for you to answer.
牙科医生总是在你无法作出回答时向你提出问题。
No sooner had we entered the hall than the ceremony began.
我们刚一进大厅，典礼就开始了。
根据本课的重要语法点，让我们来练一练吧，请选择正确的选项。
He had scarcely had time to settle down_______ he sold the house.
