9.Nowadays,we can find Public Service Advertisements in some common places,such as newspapers,magazines,the Internet,radio and television.PSAs are often run (61)for free,and are meant to educate people about health,(62)safety(safe),or any other problem that affects public welfare.PSAs use some methods,like(63)attractive (attract) pictures and clever language,but they are made (64)to serve (serve) the public.China began a nationwide public service advertising campaign in 1996.Since then,many kinds of PSAs (65)have appeared/have been appearing (appear) around the country.
You have probably seen or heard some of these PSAs,such as,"Yes to life,No to drugs"and"Knowledge changes life".These ads tell people (66)how to deal with widespread social concerns.There are also PSAs (67)that encourage people to support public service projects,such as Project Hope.Its motto is"Project Hope---educating every child".There are even PSAs to teach us how to live (68)ahealthy life.One of these is,"When you smoke cigarettes,you are killing yourself (69)slowly (slow)".People can benefit (70)fromall of these ads,and can often learn a lot by following the advice they give.
分析 短文主要对公益广告进行介绍.
解答 61.for,考查介词,for free"免费",为固定搭配.
62.safety,考查名词,由前面的health可知此处应使用safe的名词形式.
63.attractive,考查形容词,此处应使用形容词修饰后面的名词pictures.
64.to serve,考查不定式,此处应使用动词不定式充当目的状语.
65.have appeared/have been appearing,考查时态,由时间状语Since then可知句子应使用现在完成时have done的形式,也可表示动作发生在过去并且一直持续着,因此也可以使用现在完成进行是have been doing 的形式.
66.how,考查宾语从句,从句缺少疑问句,根据语境是"如何处理普遍的社会事务",应使用疑问词how.
67.that,考查定语从句,句子先行词是PSAs,引导定语从句应使用that.
68.a,考查冠词,此处泛指"一种健康的生活"应使用不定冠词a.
69.slowly,考查副词,此处应使用副词修饰谓语are killing yourself.
70.from,考查介词,benefit from"从…中受益"为固定搭配.
点评 对于语法填空这类题,一是懂得分析句子结构,二是知道充当各个句子成分的词类或词性,从语法上确定答案,当然,对于某些固定搭配也要牢记,在平时的学习中要多积累这些词汇或短语,对于句子使用的时态语态也要通过语境进行确定.
