Answer 1

【答案】

【1】for

【2】safety

【3】attractive

【4】to serve

【5】have appeared / have been appearing

【7】that

【8】a

【解析】我们经常在各大媒体看到公益广告。公益广告是非盈利性的，旨在健康、安全和其他关乎公众利益的方面给以引导教育。

【1】for。考查介词搭配。for free 免费。公益广告经常是免费的。

【2】safety。 考察名词。此处跟health，other problem并列，做about的宾语，用名词。

【3】attractive。 考察形容词作定语。attractive pictures 吸引人的图画。

【4】to serve。 考察不定式作主补。使役动词短语make sb. do sth.用于被动语态时，其后的做宾补的动词原形前要加上to，变为主补，构成be made to do sth. 结构。

【5】have appeared / have been appearing。 考察 时态。时间状语为since then，主句时态通常为现在完成时或现在完成进行时。表示自那以后（一直）以来的动作和状态。

【6】how。 考察连接副词。连接词后面通常可以用不定式来代替从句，从而简化句子构成。此处用how表示 “如何” ，后接to deal with widespread social concerns。

【7】that。 考察定语从句。先行词PSAs代入定语从句中，充当主语，因此用that。

【8】a 。 考察冠词。live a … life 过着…的生活。

【9】slowly 。 考察副词作状语。此处用副词来修饰动词are killing。

【10】from。 考察介词搭配。benefit from sth.从…中受益。人们可以从所有的这些广告中受益，并且通过听从他们所给出的建议学会很多。
