分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了中餐為什么健康,西餐為什么不健康的原因.

解答 BBCAA  DCAAB  DDABA  CDBAA
21.B 考查動詞辨析.動詞include包含(部分內(nèi)容);contain包含(全部內(nèi)容);keep保持;gain贏得;這些食物通常包含脂肪,纖維素和鹽等.這三項是食物包含的所有內(nèi)容,故B正確.
22.B 考查不定式用法.本句中不定式做定語修飾energy,前面live是不及物動詞,而energy也不是它的賓語,所有不需要接in.故B正確.
23.C 考查語態(tài).動詞measure與the energy構(gòu)成被動關(guān)系,所以使用過去分詞表示被動.句意:能量以卡路里來衡量.故C正確.
24.A 考查語法.短語be asleep表示狀態(tài),而fall asleep,go to bed/sleep都表示動作.本句指人們在睡覺的時候,也要消耗能力,應(yīng)該表示具體的狀態(tài).故A正確.
25.A 考查上下文串聯(lián).本句while與前句when形成呼應(yīng).句意:當(dāng)你在學(xué)校、步行回家的時候,你的身體都在消耗能力.B后面不能接句子,C項引導(dǎo)讓步狀語從句,D項引導(dǎo)條件狀語從句.故A正確.
26.D 考查情態(tài)動詞.情態(tài)動詞must必須,一定;can't不可能;need需要;might也許;踢足球打籃球的時候,每個小時也許只要使用400卡路里的能量.這只是一種大概的推測,無法確認(rèn).故D正確.
27.C 考查副詞辨析.副詞surely確定地;usually通常;perhaps也許,hardly幾乎不;C項與26空might同樣,都表示大概的推測,沒有確定的數(shù)字.故C正確.
28.A.考查動詞辨析.根據(jù)句意為中國飲食被認(rèn)為是世界上最健康的;故選A.
29.A 考查形容詞辨析.形容詞rich豐富,富有;poor糟糕,可憐的;good良好的;bad糟糕的;形容詞都一樣be rich in富含…;本句告訴我們中餐富含纖維素,低糖低脂肪,所以是健康食物.故A正確.
30.B 考查上下文串聯(lián).根據(jù)前句可知中國人吃的糖比其他國家的人都要更少.所以使用比較級形式less.這就是中國人通常都有白牙齒的原因.why引導(dǎo)的表語從句句通常表示結(jié)果.故B正確.
31.D 考查短語辨析.many/much too后面通常接形容詞副詞,too many修飾可數(shù)名詞復(fù)數(shù)形式,只有too much修飾不可數(shù)名詞.本句橫線后面是fat and sugar,這些都是不可數(shù)名詞,所以使用too much修飾.
32.D 考查常識和語法.很多西方人胖,主要是因為飲食中脂肪和糖分太多,鍛煉太少.名詞exercise表示鍛煉的時候,是不可數(shù)名詞.排除A項.故D正確.
33.A 考查固定搭配.短語put on weight發(fā)胖.句意:因為這一點,他們很容易就發(fā)胖;故A正確.
34.B 考查固定短語.介詞短語in the form of以…形式;西方人的飲食以薯片和薯條的形式含有很多的脂肪.故B正確.
35.A 考查上下文串聯(lián).西方人攝入糖分很多,這些糖分存在于蛋糕、軟飲料和糖果中.BCD三項都應(yīng)該使用復(fù)數(shù)形式.A項包含了其余三項.故A正確.
36.C 考查連詞.結(jié)果是很多西方人都發(fā)胖了,并且牙齒也壞了.上下文之間是并列關(guān)系,所以使用and連接上下文.but表示轉(zhuǎn)折關(guān)系,or表示選擇關(guān)系,so表示因果關(guān)系.故C正確.
37.D 考查介詞短語.短語by the age of到…歲的時候,有十分之一的人到30歲的時候就沒有牙齒了.故D正確.
38.B.考查動詞辨析.根據(jù)句意可知美國心臟協(xié)會建議人們吃高纖維食物;故選B.
39.A.考查形容詞辨析.根據(jù)句意水果,蔬菜和谷物脂肪含量低、無膽固醇,也是纖維的良好來源;故選A.
40.A.考查形容詞辨析.a(chǎn) balanced diet,平衡的膳食;根據(jù)句意所以為了保持健康,人們應(yīng)該有一個平衡的膳食;故選A.

點評 考察學(xué)生的推理判斷能力和聯(lián)系上下文的能力,在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.此類的填空題一定要聯(lián)系上下文,根據(jù)上下文的內(nèi)容加上自己的理解,再作出正確的判斷

19.People are always looking for lost cities and occasionally one is found:Borobudur in Indonesia,for example.But perhaps some of the places people look for never existed-or did they?Here are just a few famous mythical(傳說中的)cities.
El Dorado.
El Dorado is a story that began in 1537,when Spanish explorers found the Muisca people in the mountains of what is now Colombia.They heard the story of a man who covered himself with gold and dived into a lake.Then people began to talk of El Dorado-‘the golden man'Soon people started to think of El Dorado as a place,too一 a city of gold and amazing riches.Nowadays,the name'El Dorado'is still used to mean‘a(chǎn) place where you can get rich quickly.'
Atlantis
There was once an island in the middle of the Atlantic Ocean.It was the mythical island of Atlantis.The people of the island were very rich,thanks to the natural resources(資源)on their island.For hundreds of years,they lived simple lives.But slowly they began to change.They started to want power.So the gods decided to destroy Atlantis.Suddenly,the island and its people were swallowed(淹沒)by the sea and were never seen again.
Shambhala
In Tibetan Buddhist tradition,Shambhala is a mystical (神秘的)country that is hidden somewhere behind the Himalayas.Shambhala is a word from an old language that means‘place of peace'or‘place of happiness'.It is said that there is no war in Shambhala,and in the future,when the world is full of war,a huge army will come out of Shambhala,destroy the world's bad rulers,and start a new Golden Age.Some people say this will happen in 2424.

10.A story tells of a businessman in a small town who had twin sons.The boys worked for their father in the store he owned,and when he died,they took over the store.
Everything went well until the day a dollar bill disappeared.One of the brothers had left the bill on the cash register(現(xiàn)金出納機(jī)) and walked outside with a customer.When he returned,the money was gone.He asked his brother,"Did you see that dollar bill on the cash register?"His brother replied that he had not.But the young man kept questioning.
"Dollar bills just don't get up and walk away!Surely you must have seen it!"There was a little of anger in his voice.Resentment (怨恨) set in and it divided the young men.They finally decided they could no longer work together and a dividing wall was built down the center of the store.For twenty years anger grew,spreading to their families.
Then one day a man in a car stopped in front of the store.He walked in and asked the clerk,"How long have you been here?"The clerk replied that he'd been there all his life.The customer said,"I must share something with you.Twenty years ago I came into this town.I hadn't eaten for three days.I came into this store from the back door and saw a dollar bill on the cash register.I put it in my pocket and walked out.All these years I haven't been able to forget that.I know it wasn't much money,but I had to come back and ask for your forgiveness."
The stranger was amazed to see tears well up in the eyes of this middle-aged man."Would you please go next door and tell that same story to the man in the store?"he said.Then the man was even more amazed to see two middle-aged men,who looked very much alike,embracing(擁抱) each other and weeping together in the front of the store.
After twenty years,the wall of resentment that divided them came down.

28.The underlined sentence in Paragraph 2meansB.
A.I didn't see the customer off with the dollar bill
B.there was no possibility that the money disappeared itself
C.it was a pity that money couldn't move like humans
D.money can only be carried to other places with people
29.After 20years,the man came back to the store in order toC.
A.pay back the money he owed
B.thank the owner for having lent him money
C.a(chǎn)pologize to the owner for stealing the money
D.help the twins become united again
