●必背句型
1.强调句型及其变化形式
教材原句
（1）It was during the “March on Washington DC”in 1963 that he gave the speech “I Have a Dream”,which inspired people of all races to fight for equality.
正是在“华盛顿特区大游行”期间，他作了“我有一个梦想”的演说，该演说激励着各种族人民为争取平等而斗争。

特别提示
注意强调句式的结构：It is（was）+被强调的成分+原句结构。

上句强调的是时间状语。

（2）What is it that makes the ocean such a great place to live?
是什么使海洋成为如此优越的生存之所？
特别提示
本句是强调句型的特殊疑问句形式。

我们可将其还原成陈述句：
It is water that makes the ocean such a great place to live.
补充例句
（1）It is the chemical structure of water that makes it an excellent medium for life.
是水的化学结构使它成为绝佳的生命存在的介质。

2.What和whatever引导的名词性从句
教材原句
（1）Even though the pure water is what gives sea water its main properties,the salinity of sea water affects both its weight and freezing point.
虽然纯净水给海水提供了主要特性，但海水的高含盐量影响着其重量和冰点。

特别提示
连接代词what=the thing which,相当于汉语中的“的”字结构，表示“……的人（事）”，其引导的名词性从句可作主语、宾语或表语。

掌握what-句的关键是弄清what的“分身术”：既在从句中充当主语或宾语，又在逻辑上充当主句中的主语或动词宾语。

（2）What all these groups have in common is that they ask to be treated with respect,share the rights to work,good housing conditions and education and be treated equal to other people in all ways.
这些团体所共有的愿望是要求受到尊重，享有工作、好的居住条件和受教育的权利以及在各方面受到平等对待。

（3）The nutrients in whatever falls into the ocean will quickly become available to other living creatures.
任何东西进入海洋后，其营养物质很快就会被其他生物获得。

句中的whatever=anything that,与what功能相同，只是语气强一些。

一般认为孩子要什么就给他（她）什么是不明智的。

典例剖析
【例1】（2004年全国卷Ⅲ,21）I often see lights in that empty house.Do you think I ______report it to the police?
A.should
B.may
C.will
D.can
剖析：说话者常见空房子有灯光，感到不正常，不知是否应报警，于是征求听者意见。

【例2】（2004年上海,30）The number of deaths from heart disease will be reduced greatly if people ______to eat more fruit and vegetables.
A.persuade
B.will persuade
C.be persuaded
D.are persuaded
剖析：首先，persuade 是及物动词，使用时要么带宾语，要么用被动式。

据此可排除A、B两项；由主句谓语动词will be reduced可知从句应为真实条件句。

在时间或条件状语从句
中，谓语动词用一般时表达将来的动作。

答案：D
【例3】（2004年上海，47）After the trainer was sure that the whale could look after itself,he ______it into the sea.
A.transported
B.unloaded
C.released
D.handled

答案：C。
