解答 Smokers in China are said to account for 45percents of the country's population．Most are young people and some are even middle school students．Why do so many people enjoy smoke？Some consider it as a pleasure； some believe that it can refresh them．Others consider it as a relief from pressure．Besides，it does great harm not only to the smoker，but also to others around asmoker．Smoking waste much money and causes many diseases．What's bad，a lot of fires∧caused by careless smokers．Nowadays，many people have realized the harmful of smoking and decide to give it up．If you are not a smoker，never to touch it and never start smoking．
詳解：
1．percents改為percent；考查名詞，percent沒有復(fù)數(shù)形式，以它所修飾的名詞來判斷謂語的單復(fù)數(shù)．    
2．smoke改為smoking；考查非謂語動詞，enjoy doing是固定搭配，意為"喜歡做某事"．
3．them改為themselves；考查反身代詞，分析句意為"有些人認為吸煙能使他們自己消除疲勞"，故用themselves，與前面的some呼應(yīng)．
4．Besides改為However；考查連詞，結(jié)合語境分析句上下文之間為轉(zhuǎn)折關(guān)系，故用however表示"然而"．
5．a(chǎn)改為the；考查冠詞，此處smoker指代上一句中提到的smoker，故用the表示特指．
6．waste改為wastes；考查主謂一致，動名詞形式smoking作主語，謂語動詞用單數(shù)形式．
7．bad改為worse；考查固定搭配，what's worse 是固定搭配，意為"更糟糕的是"． 
8．caused前加are；考查動詞的語態(tài)，主語a lot of fires和動詞cause是動賓關(guān)系，故加系動詞are構(gòu)成被動語態(tài)．
9．harmful改為harm；考查名詞，定冠詞the后面跟名詞形式，此處作動詞realize的賓語．
10．去掉to；考查祈使句，這是一個否定祈使句，要用動詞原形，故把to去掉．

點評 短文改錯時要注意句子中人稱和數(shù)是否一致，時態(tài)是否一致．各種詞性之間的區(qū)別以及一些常用句型，固定短語的應(yīng)用．這類題型一般考查的是基礎(chǔ)知識，平時應(yīng)注重積累，熟記一些句型及習(xí)慣常用結(jié)構(gòu)．
