翠花，上真题：

People nowadays are surrounded by all kinds of advertising. Some people believe thatadvertising has more negative than positive influences on people’s lives. 

To what extentdo you agree or disagree? 

今天我们一起分析一段正方观点：

 If ads are created to be memorable and thought-provoking, they can drawpublic’s attention and change people’s attitudes and behaviours as well. For example, governments often disseminate important messages to a community through public serviceadvertising. It can effectively raise the public’s awareness, ranging from road safety to public health,animal rights, and environmental protection, which is definitely beneficial to the whole ofsociety.

从语法的角度，第一句话是条件状语从句。

引导条件状语从句最常见的连词是if,表示在某种条件下，一件事很可能发生。

句子的形式：

1. 主谓宾 if 主谓宾

例句：We will stop playing golf if it rains.

如果下雨，我们就停下来不打高尔夫球了。

2. If 主谓宾，主谓宾

把if引导的从句放在主句前面，叫做状语前置。注意，中间的逗号不能省略。

例句：If people obey the traffic rules, there will be fewer accidents.

如果人们遵守交通规则，事故就会减少。

本段还使用了举例的论证方法。举例时可以用的词包括：

for example, for instance, ...are typical examples of..., ....can be exemplified by...

例句：Melbourne's economic growth is exemplified by the numerous new buildings that are under construction. 大量正在建设中的新建筑体现了墨尔本的经济增长。

本段中，值得积累的单词有：

memorable

thought-provoking

adj. 发人深省的

provoke

vt. 激起、惹怒、煽动

例句：The dog would not have attacked Emma if it had not been provoked. 这只狗如果没有被惹怒，它是不会攻击艾玛的。
