Question

20．Innocent Fast Food Restaurant
A study by academics from the University of California and Northwestern University claimed that"the causal link between the consumption of restaurant foods and obesity （肥胖） is minimal at best．"
It argued that a tax on high-calorie （卡路里） food，（33）whichwas proposed by many health campaigners in the US and Britain，might therefore not be an effective way for governments to deal with the problem．
It analyzed data on calorie intake around the country，which （34）had been collected（collect） before under the leadership of the US Department of Agriculture．The study found that people living closer （35）torestaurants were not significantly more likely to be obese than people living further away，（36）indicating（indicate） that easy access to restaurants had little effect．
It also showed that while restaurant meals typically held more calories than home-produced food，many customers often make up for this by eating （37）less（little） throughout the rest of the day．
"Obese people who ate at restaurants，"the study indicated，"also eat more when they eat at home．"
The US government estimates （38）thatabout one in three Americans，or 100 million in total，are obese．Last month it was predicted that 75 percent of Americans would be overweight in 2020．
The problem is thought to cost Americans between 150billionand170 billion in annual medical costs．
"While taxing restaurant meals might means （39）changing（change） where these consumers eat，"the study's authors，Michael Anderson and David Matsa，wrote，"our study results suggest that a tax （40）wouldbe unlikely to affect their potential tendency to overeat．"

Answer 1

分析 加利福尼亞大學和西北大學的一項研究發現"快餐食物和肥胖之間并沒有必然聯系"．  在英國和美國，眾多的健康人士建議對高卡路里食物征稅，但是這項研究卻表明這樣做也許并不是政府解決肥胖問題的有效途徑． 該研究分析了由美國農業局統計的關于美國各個地區人們卡路里攝入量的數據．結果發現住在餐館附近的人并不比遠地方的人更加肥胖，這就意味著離快餐店近并不是造成肥胖的直接原因．研究還表明雖然快餐食物通常含有比家里自制的食物更高的卡路里，但是人們在吃完快餐食物之后往往會減少一天食物的攝入量，這樣副作用就抵消了． 研究表明，在餐館吃飯的肥胖人士在自己家里的時候往往也會吃得很多． 美國政府估計每一百個美國人中間就有一個肥胖者．上個月的一項調查預估到2020 年75%的美國人都會超重．肥胖問題每年都會花費美國政府1500 億到1700 億美元的醫療費用． 研究者認為，"盡管向高卡路里食物征稅可能改變人們的就餐地點，但是卻不能改變他們潛在的過度飲食的習慣．"

解答 33．which；考查關系代詞，結合上下文語境，這里用關系代詞which指代It argued that a tax on high-calorie （卡路里） food這件事．
34．had been collected；考查動詞的時態，短文通篇用了過去時態，這里句子中又出現了before，說明動作發生在過去之前，即"過去的過去"，所以要用過去完成時．
35．to；考查固定搭配，"距離…很近"用短語"be close to"，在文中形容詞close用了它的比較級形式．
36．indicating；考查分詞作狀語，結合上下文，前面的句子動詞indicate之間是主謂關系，所以用現在分詞作狀語．
37．less；考查比較級，結合上下文，這里認為消費者"吃完快餐后回家吃的就少了"，作者把吃快餐和在家吃的作了比較，所以要用比較級．
38．that；考查關系代詞，這里用關系代詞that引導賓語從句，作動詞estimates 的賓語．
39．changing；考查習慣用法，動詞mean后面通常跟doing或to do，mean doing表示"意味著"，mean to do表示"打算"；結合上下文這里應該用mean doing．
40．would；考查情態動詞，結合句意空格處用情態動詞would表示語氣更加委婉，意為"征稅將不可能改變他們過度飲食的習慣"．

點評 在短文改錯當中，首先要從整體掌握短文大意，結合上下文語境并充分運用平時掌握的基礎知識，充分運用所學的基礎知識，包括一些實詞和虛詞的用法，固定短語搭配，習慣性用法，結合上下文整體關系，找出錯誤并加以修正．
