　　现今，无论我们走到哪里，几乎都可以看到广告。我们对广告太习以为常了，甚至常常意识不到一天当中看到和听到多少广告。我对广告做了一些研究，有一些非常重要的信息同大家分享。

　　什么是广告？

　　广告使用文字和图片来说服人们购买某种产品或服务，或者是相信某种理念。报纸、杂志、互联网、广播及电视是最普遍的广告载体。广告主要分为两类--商业广告和公益广告。商业广告是一种某人为了推销某种产品或服务而花钱做的广告。公益广告往往是免费投放的，旨在就健康、安全或其他影响公共福利的问题教育公众。

　　Does an advertisement tell people the complete truth?

　　There are laws to protect people from⑭ advertisements that cheat⑮ people. However, we still must be aware of⑯ the skilful methods used in ads to try and sell us things⑰. Even if⑱ an ad does not lie, it does not mean it is altogether⑲ innocent⑳. One toothpaste ad declares, 'Bright­Teeth fights bad breath\s\up1(21(21)！' This statement tries to fool\s\up1(22(22) you into assuming that the toothpaste cures\s\up1(23(23) bad breath, yet it does not say that！All it says is that it fights it, and that is not the same thing at all\s\up1(24(24). One grocery\s\up1(25(25) tells customers, 'You are proud of your cooking, so shouldn't you buy the very freshest food？' This ad is very clever, because it tells customers they are good cooks. However, it never says that this grocery has the freshest food! The grocery just hopes that when you read the ad, you will feel pleased\s\up1(26(26) with the nice comment\s\up1(27(27)， remember the words 'freshest food'， and make a mental\s\up1(28(28) connection with the food in the grocery. We must not fall for\s\up1(29(29) this kind of trick\s\up1(30(30)！,⑭protect ... from ... 保护......免受......
