  Let's say you've decided you want to eat more healthfully.However,you don't have time to carefully plan menus for meals or read food(41)G at the supermarket.Since you really (42)C    yourself to a healthier lifestyle,a little help would come in handy,wouldn't it?This is where a"choice architect"can help (43)I some of the burden of doing it all yourself.Choice architects are people who organize the contexts in which customers make decisions.For example,the person who decides the layout of your local supermarket-including which shelf the peanut butter goes on,and how the oranges are piled up-is a choice architect.
  Governments don't have to (44)F healthier lifestyles through laws  for example,smoking bans.Rather,if given an environment created by a choice architect-one that encourages us to choose what is best-we will do the right things.In other words,there will be designs that gently push customers toward making healthier choices,without removing freedom of choice.This idea combines freedom to choose with (45)E hints from choice architects,who aim to help people live longer,healthier,and happier lives.
  The British and Swedish governments have introduced a so-called"traffic light system"to (46)B foods as healthy or unhealthy.This means that customers can see at a glance how much fat,sugar,and salt each product contains (47)K by looking at the lights on the package.A green light(48)J that the amounts of the three nutrients are healthy; yellow indicates that the customer should be (49)A; and red means that the food is high in at least one of the three nutrients and should be eaten in(50)H.The customer is given important health information,but is still free to decide what to choose.

分析 文章介紹人們都希望有健康的生活方式和飲食,但是沒有時間計劃,這里介紹了兩種方法,一種是"choicearchitect",還有一種是"交通燈系統(tǒng)".

解答 41.G   42.C   43.1    44.F   45.E   46.B   47.K   48.J    49.A   50.H
41.G. 本題考查名詞搭配.由于在超市里,所以是閱讀食物標簽(labels).故選G. 
42.C. 本題考查動詞短語搭配.根據所給詞匯以及„yourself to a healthier lifestyle,只有commit yourself to(承諾„„)符合句意.故選C. 
43.I. 本題考查動詞用法.根據后面內容some of the burden of doing it all yourself以及前面動詞help可知此空應填relieve(減輕),構成"„„能夠有助于減輕獨自做這事的一些負擔".故選I. 
44.F. 本題考查動詞用法.根據句子邏輯,此句意思為"政府不必通過法律來強加(impose)更健康的生活方式,如戒煙".故選F. 
45.E. 本題考查形容詞用法.根據設空,本空填形容詞,而alert(警覺的)不符合句意,只有gentle(文雅的)符合句意.故選E. 
46.B. 本題考查動詞短語用法.本句句意為"英國和瑞典政府引進了所謂的交通燈系統(tǒng)來吧食物分類為健康的或不健康的",短語classify„as„表示"把„„分類為„„",故選B. 
47.K. 本題考查副詞用法.根據„customers cansee at a glance how much fat,sugar,and salt each product contains__47__bylooking at the lights on the package(顧客們只要看包裝上的指示燈一眼就能看出每一個產品含有多少脂肪、糖和鹽)可知,此空填simply.故選K. 
48.J. 本題考查動詞用法.由于空后所接的是賓語從句,所以該空填及物動詞,結合后面indicates的意思可知,該空填signals(表示).故選J.
49.A.本題考查形容詞用法.根據前面"綠燈表示三種營養(yǎng)的量是健康的"可知"黃燈表示三種營養(yǎng)的量可能有問題",因此消費者應當留心(alert).故選A. 
50.H. 本題考查名詞詞義.根據句子red means that the food is high in at least one of the three nutrients(紅燈意味著至少三個營養(yǎng)中的一個是高的)可知,這樣的食物應當有節(jié)制地(in moderation)吃.故選H.

點評 本文屬于詞匯運用類的11選10閱讀題型,把詞匯的考查放在了語言環(huán)境中,不是單純的考查詞匯,文章題干均清晰明了,并提供了足夠的上下文支撐供考生答題.同時,詞匯題的難度分布也較為合理,確保了各個層次的考生都能得分.因此,情景理解和語言運用的味道比較濃厚,注重考查理解能力和邏輯推理能力的試題較多.

7.Driving to the airport in the early morning,I felt excited.Although I was heading abroad for my first time alone,I felt cheerful and enthusiastic.I was spending the summer in Paris.
While looking for more interesting things to do besides sleeping and eating,I found programs for learning languages abroad,and jumped at the chance to study French in this city known for its art,fashion,food,and culture.As I arrived at the airport where I would leave my family,I still felt only great happiness.I excitedly made my way through security,leaving my loved ones behind.
My connecting flight was in Frankfurt,Germany,14hours from Denver.Sitting in a crowed plane watching bad movies couldn't dampen my excitement.When the woman next to me asked me where I was going,I happily answered and was pleased to note a tone of jealousy in her response.
But when I arrived in Frankfurt,fear and anxiety began to set in.Being in an enormous,busy building in a country where I couldn't speak the language was frightening,but as I found my way,I gained confidence.When I boarded the second plane and discovered that the flight was less than an hour,I was filled with excitement as I thought of how I would manage in a country with a new language.
When I stepped on the ground of Pairs for the first time,I was extremely happy and excited.I gathered my bags and joined the crow of people waiting for friends and family.I quickly had my first experience trying to communicate in a language that I had only practiced in school.As I left the airport,I looked for familiar monuments I had read about,but the landscape looked very ordinary.Then,with one sharp turn,the Eiffel Tower came into view,and I was finally in Paris.

21.Which of the following is True according to the passageD?
A.It was the first time that the writer had traveled abroad.
B.In the new term the writer was to study French in Paris.
C.The crowded plane made the writer less excited.
D.The writer flew to Paris via another country.
22.What can we learn from the passageC?
A.The writer was travelling with a woman friend of her parents'.
B.Arriving in Paris,the writer saw some family friends waiting for her.
C.The writer was not along when travelling to the airport in Denver.
D.The writer had great difficulty communicating with people in French.
23.What is the passage mainly aboutA?
A.The writer's excitement and happiness on her journey to Paris.
B.The writer's exciting experiences of studying French in Paris.
C.The writer's expectation for French art,fashion,food and culture.
D.The writer's excitement resulting from her first ride on a plane.

14.I was sure that I was to be killed.I became terribly nervous.I fumbled(摸索) in my pockets to see if there were any cigarettes,which had escaped their search.I found one and because of my shaking hands,I could barely get it to my lips.But I had no matches,they had taken those.I looked through the bars at the guard.He did not make eye contact with me.I called out to him"Have you got a light?"He looked at me,shrugged and came over to light my cigarette.As he came close and lit the match,his eyes unconsciously locked with mine.At that moment,I smiled.I don't know why I did that.Perhaps it was nervousness,perhaps it was because,when you get very close,one to another,it is very hard not to smile.In any case,I smiled.In that instant,it was as though a spark jumped across the gap between our two hearts,our two human souls.I know he didn't want to,but my smile leaped through the bars and caused a smile on his lips,too.He lit my cigarette but stayed near,looking at me directly in the eyes and continuing to smile.
I kept smiling at him,now thinking of him as a person and not just a guard."Do you have kids?"he asked."Yes,here,here."I took out my wallet and nervously fumbled for the pictures of my family.He,too,took out the pictures of his family and began to talk about his plans and hopes for them.My eyes filled with tears.I said that I feared that I'd never see my family again,never have the chance to see them grow up.Tears came to his eyes,too.Suddenly,without another word,he unlocked my cell and silently led me out.Out of the prison,quietly and by back routes,out of the town.There,at the edge of town,he released me.And without another word,he turned back toward the town.
21.What had happened to the man before?C
A.He had been badly treated.
B.He had killed someone.
C.He had been searched.
D.He had been forbidden to get in touch with anyone.
22.Why did the man want to smoke cigarettes?B
A.Because he was sure he was to be killed.
B.Because he wanted to ease his nervousness.
C.Because he wanted to talk to the guard.
D.Because he was used to smoking cigarettes.
23.Which of the following is true according to the passage?D
A.The man was a heavy smoker.
B.The man smiled to please the guard.
C.The guard set the man free with permission.
D.The man hadn't thought the guard would set him free.
24.What do you think finally saved the man's life?A
A.The smile.B.The cigarette.C.The tears.D.The wallet.

I still remember my middle school life in Yibin.I was then in a school for student from other places.As we were all left home at an early age,we meet lots of problems in our daily life.We had to do the washing,cleaning but shopping by us.However,we seldom felt lonely or helpless.We enjoyed our happy life.At weekends,we would play basketball on playground,swim in the pool or going for a picnic in the park.We were living in a bigger family.
We treated each other as brothers and sisters.It has been one year when we graduated,but those memories are as sweetly as ever before.
