Answer 1

分析 作者小時候認為生活在城市很快樂，現(xiàn)在作者的愿望實現(xiàn)了，但作者又懷念農(nóng)村的家鄉(xiāng)，因為城市污染嚴重，全球變暖已經(jīng)成為一個嚴重的問題，所以我們必須找到方法來保護我們的地球．

解答 When I was a child，I hoped to live in the city．I think I would be happy there．Now I am living in a city，but I miss my home in∧countryside．There the air is clean or the mountains are green．Unfortunately，on the development of industrialization，the environment has been polluted．Lots of studies have been shown that global warming has already become a very seriouslyproblem．The airs we breathe in is getting dirtier and dirtier．Much rare animals are dying out．We must found ways to protect your  environment．If we fail to do so，we'll live to regret it．
詳解：
1．think改為thought；考查動詞的時態(tài)，句意：我認為在在那兒很快樂．這里用一般過去時，表示"過去認為"
2．countryside前加the；考查冠詞，句意：但是我想念農(nóng)村的家鄉(xiāng)．這里countryside是特指，故用定冠詞the．
3．or改為and；考查連詞，分析句意為"那里山綠并且空氣新鮮"．前后句為并列關(guān)系，故用連詞and．
4．on改為with；考查介詞，with the development of是固定短語，意為"隨著…的發(fā)展"．
5．been去掉；考查動詞的語態(tài)，主語Lots of studies 與動詞show為主動關(guān)系，這里不需要用被動語態(tài)．
6．seriously改為serious；考查形容詞，此處用形容詞作定語修飾名詞．
7．a(chǎn)irs改為air；考查名詞，air為不可數(shù)名詞，沒有復(fù)數(shù)形式． 
8．Much改為Many；考查近義詞辨析，名詞animals為可數(shù)名詞的復(fù)數(shù)形式，故用many修飾，much修飾不可數(shù)名詞．   
9．found改為find；考查動詞，情態(tài)動詞must后接動詞原形．
10．your改為our；考查形容詞性物主代詞，分析句意為"我們必須找到方法來保護我們的地球"．故用our．

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)．
