[5]B.是非題。本題問“根據(jù)文章，下面哪個說法不正確？”我們第一步是要瀏覽四個選項。A的意思是“人們之所以喜歡家庭烹調(diào)有好幾個原因。”B的意思是“大多數(shù)家庭喜歡家庭烹調(diào)，這成了一個問題。”C的意思是“家庭烹調(diào)的氣味使得我們大多數(shù)人感受良好?！盌的意思是“家庭聚餐可以把家庭成員聚在一起?！钡诙蔚牡谝痪涮岬搅巳藗兿矚g家庭烹調(diào)的另一個原因，言下之意就是人們喜歡家庭聚餐有好幾個原因；所以，A是正確的。最后一段的第三句告訴我們C也是正確的。第一段的第三句意思和D一樣，所以D也是正確的。最終，我們得知答案是B。

第二篇：北郵網(wǎng)絡學院大學英語2階段作業(yè)

一、閱讀理解（共1道小題，共25.0分）

1.In the eighteenth century young ladies in Italy knew history and geography little.Once the French officer in Rome was giving a ball to which many important people were invited.The Italian Minister（大臣）came very late.A young lady, who knew him, saw him enter the ball-room and asked why he was so late.“Oh, nothing important,” answered the Minister.“Our head forgot to take his letters with him and went back to his hotel to bring them.If he had left them in Brazil we should have had to wait at least six months for them.” “Is Brazil so far from Rome?” asked the lady, who knew very little geography.“It is in the New World,” said the Minister.“In the New World?” repeated the lady in great surprise.“Yes, in the New World, which was discovered by Christopher Columbus.” When the young lady heard this, she rushed into the middle of the ball-room and shouted as loud as she could: “Ladies and gentlemen, have you heard the latest news? A new world has just been discovered by a certain Christopher Columbus.” 1.Why was the Minister late? A.The head left his letters in Brazil.B.He had a traffic accident.C.The head had to go back to Brazil.D.The head left his letters in the hotel.2.Where did the head leave his letters? A.In the hotel.B.In Brazil.C.In his office.D.In Rome 3.Why did the young lady shout? A.She wanted to tell the surprising news.B.She was the hostess of the ball.C.She knew the Minister.D.She had never heard about Columbus.4.Her shouting showed she was______.A.clever B.lack of knowledge C.thoughtless D.knowledgeable 5.The best title for the passage is ______.A.The New World B.Surprising News C.An Ignorant Italian Woman D.Christopher Columbus

試題分值：25.0 得分：[5, 5, 5, 5, 5] 提示：[1]D.細節(jié)題。本題問“為什么大臣遲到了？”中心詞是“Minister late”。答案在第三段。該段大意是“‘哦，沒什么嚴重的事情’大臣回答道?！覀兩纤就泿帕?，所以他就回賓館取信去了。如果他把信件遺留在巴西的話，那我們可要等上至少六個月了。’”據(jù)此，可知本題答案是D。

[2]A.細節(jié)題。本題問“那個大臣的上司把信忘記在什么地方了？”中心詞是“head”和“l(fā)etters”。答案在第三段，該段大意請參考第一題。答案是A。

[3]A.細節(jié)題。本題問“為何那個年輕女士叫了起來？”中心詞是“the young lady shout”。答案在最后一段，該段大意是“女士們、先生們，你們聽說了最新的消息了嗎？一個叫哥倫布的人不久剛發(fā)現(xiàn)了一個新世界?！睋?jù)此，可知答案是A（她想告訴大家這個驚人的信息）。B的意思是“她是舞會的女主人”，C的意思是“她認識那個大臣”，D的意思是“她從沒聽說過哥倫布”。[4]B.推斷題。本題問“她的叫喊表明她_______?！蓖茢囝}一般需要我們先瀏覽一下選項。A的意思是“聰明的”，B的意思是“知識缺乏的”，C的意思是“無思想的，笨的”，D的意思是“有見識的”。根據(jù)第三題的解釋我們可以看出這名女士對哥倫布發(fā)現(xiàn)新大陸（新大陸是15世紀末發(fā)現(xiàn)的，而本文的背景是18世紀）的這種大事都不知道，可見其缺乏知識。據(jù)此，答案是B。

[5]C.中心思想題。本題讓我們給文章選個最好的標題。我們可以先瀏覽每個段落的第一句話。第一段就是一句話，該句大意是“十八世紀的意大利少女,她們的歷史知識、地理知識一般來說非常貧乏?！弊x到這里，我們應該可以知道這樣的一個句子明顯就是文章大意的概括，所以題目就要和此相關。當然，你也可以再繼續(xù)讀幾段，你會發(fā)現(xiàn)文章出現(xiàn)了一名女士和一位意大利大臣之間的對話。最終，我們選擇C（一個無知的意大利女性）。

句首的Seen是過去分詞，引出一個過去分詞短語，在句中作狀語。

過去分詞作狀語應注意，過去分詞與句子主語之間的關系

過去分詞作狀語表示被動或完成的動作。過去分詞提與句子主語之間通常存在邏輯上的動賓關系。如： 示: Grown in rich soil, these seeds can grow fast.種在肥沃的土壤里，這些種子能長得很快。

分詞在句子中作狀語，分詞的邏輯主語與句子的主語一致。使用何種分詞，要取決于分詞與句子主語之間的關系：主謂關系用現(xiàn)在分詞，動賓或被動關系用過去分詞。比較：

Seen from the sky, our city is very beautiful.(our city與see之間是被動關系)Seeing from the sky, we find our city is very beautiful.(we與see之間是主謂關系)16.17.There were still situations__________ which I couldn't be certain my decision had been the right one.A.upon B.on C.in D.with 知識點: 第一部分 學生答[C;] 標準答案: 案: 得分: [5] 試題分值:

試題分值：50.0 得分：[5, 0, 0, 0, 5, 0, 0, 0, 0, 5] 提示：[1]B.考查句意理解。本句大意是“我們稱呼它為‘希望’?！边@里只有B的意思適合。

案: 選項的意思都不適合。

[3]A.考查句意理解和常識。本句意思是“希望6個月大的時候開始吃竹子嫩芽和______?！痹倏催x項的意思：leaves（葉子），vegetables（蔬菜），trees（樹木），chips（土豆片）。根據(jù)常識，我們知道熊貓吃竹葉，所以選擇A。[4]D.考查句意理解。本句意思是“她長成了一個_______年輕熊貓，重達35克?！边@里選擇“healthy”，意思是“健康的”。[5]C.考查句意理解。本句大意是“當希望20個月大的時候，她就不得不照看自己了，______她媽媽又生了個熊貓寶寶?！边@里讓我們選擇連詞，“because”表示原因，用在這里最適合。

[6]C.考查句意理解。本句大意是“______，熊貓在野外生活會困難重重?！边x項的意思分別是：luckily（幸運地），suddenly（突然地），sadly（悲傷地，說來遺憾），especially（特別，尤其）。這里選擇C，其意思最適合此處。

[7]D.考查句意理解和詞匯辨析。本句大意是“這里有一些像希望這樣的熊貓將來可能會遇到的______?！焙苊黠@空格處的意思是“問題”。下一步就是要辨析“question”和“problem”的區(qū)別了。question 指主觀存在的“疑惑、疑問”，所以是需要“回答”（answer）的； problem 指客觀存在的和遇到的疑難問題，有時指較嚴重的問題，所以是需要“解決”（solve，work out）的。本句中指的是熊貓在生活中遇到的客觀問題，所以自然選擇D。

[8]A.考查句意理解。本句大意是“如果農(nóng)民________樹木和森林，那么熊貓就無處生活了?！边x項的意思是：cut down（砍伐），plant（種植），protect（保護），water（澆水）。顯然，此處應該選擇A。[9]B.考查句意理解。本段這兩句大意是“如果熊貓媽媽離開了熊貓寶寶，人們通常會帶走這些熊貓寶寶。人們會認為這些寶寶需要_______。”四個選項的意思分別是：money（錢），help（幫助），clothes（衣服）和family（家庭）。此處明顯選擇B最適合。[10]A.考查句意理解。“do

nothing”的意思是“什么都不做”。本句大意是“如果我們什么都不做，不久世界上就沒有熊貓了?！?/p>

B 5.0 解析：該題選B，題目大意是“除了在學校任教之外，珍妮還在家里給一些孩子上鋼琴課”。in addition和in addition to的不同

in addition to和in addition都是很常見很常用的短語，都有“除了、還有”的意思，但它們的用法是完全不同的，所以今天我們就來區(qū)分一下。In addition to整個詞組相當于一個介詞，所以to的后面要接賓語。例如: In addition to native plants, this garden 提示: contains numerous trees and flowers from overseas.除了當?shù)氐闹参镏猓@座花園還有無數(shù)來自海外的花草樹木。

In addition相當于副詞，通常放在從句的句首，后面接完整的句子。例如：

This garden has the best collection of native plants.In addition, it contains numerous trees and flowers from overseas.這座花園有當?shù)刂参锏淖罴颜洳亍Ａ硗?，它還有無數(shù)來自海外的花草樹木。6.7.While my wife and my children were away for the long weekend, __________.A.I alone in the house B.I alone had a house C.I had the entire house to myself D.I got a house to myself 知識點: Choice3

C 5.0 學生[C;] 標準答案: 答案: 得分: [5] 試題分值: 解析：該題選C，題目大意是“我告訴男孩不要緊提示: 張”。

10.11.I would _________ play tennis than football.A.quite B.simply C.rather D.like 知識Choice4 點: 學生[C;] 標準答案: 答案: 得分: [5] 試題分值:

C 5.0 解析：該題選C，題目大意是“我寧愿打網(wǎng)球，而不踢足球”。

“would rather + 動詞原形”表示“寧愿”，是英語中常見的一個慣用句式，美國英語中多用had rather。would(had)在此決無“過去”之意，它是一個情態(tài)助動詞，且無詞性、時態(tài)變化。

1.He’d rather work in the countryside.她提示: 寧可到農(nóng)村去工作。2.Mr Li would rather not listen to rock music.李先生不愿意聽搖滾音樂。

3.If you’d rather be alone, we’ll all leave here.如果你寧愿獨自呆著，那我們 都離開這兒。4.You would rather stay at home and do some reading this evening.今晚你最好 呆在家中讀點書。

5.You can go out and enjoy yourself if you like, but I would rather stay home and read.如果你愿意你可以外出去玩，但我寧愿呆在家里讀書。

如果在兩者中進行取舍，表示“寧愿??而不愿??，與其??寧可??”的意思時，則可用would rather?than?或would?rather than?的句型，例如 1.I would rather watch TV at home than go to the cinema.我寧可在家看電視而不愿去看電影。

2.The children would walk there rather than take a bus.孩子們寧愿步行去那里而不愿乘公共汽車。

注：在would rather?than?句型中，rather與than后都應跟不帶to的動詞不定式。

12.13.What shall I do to ________ this _________ getting dirty? A.from?keeping B.keep?from C.keeping?from D.keep?on

知識點: Choice4

B 5.0 學生[B;] 標準答案: 答案: 得分: [5] 試題分值: 解析：該題選B，題目大意是“我該怎樣防止這東西不被弄臟呢”？ keep sb / sth from +分詞：是阻止，妨礙的意思

1.I hope you will keep from doing anything 提示: rash.我希望你不要做出任何魯莽的事情來。

2.I horse around quite a lot, just to keep from getting bored.我胡鬧了一陣兒，只是為了擺脫厭煩。

3.Hearing the words, he couldn′t keep from laughing.聽了這話，他不由得笑了起來。14.15.Mrs.Smith went on a diet and in three months ___________ her weight to 100 pounds.A.brought back B.brought up C.brought down D.brought about 知識點: Choice4

C 5.0 學生[C;] 標準答案: 答案: 得分: [5] 試題分值: 解析：該題選C，題目大意是“史密斯太太限制飲食，四個月下來就把體重降到一百磅”。

bring down：reduce；cause to fall 減少，降低 1.bring down the temperature降低溫度 2.bring down the income taxes降低所得稅

提示: 3.Zhang li went on a diet and in three months brought down her weight to 50 kilos.張莉節(jié)制飲食，三個月把體重減到了五十公斤。4.The nurse gave him an injection to bring down the temperature.護士給他注射了一針，以降低體溫。

16.I knocked several times __________ an old man answered the door.A.as B.when C.while D.before 知識點: Choice4

D 學生答[D;] 標準答案: 案: 得分: [5] 試題分值:

5.0 解析：該題選D，題目大意是“我敲了好幾遍門，才有一位老人來應門”。

連詞before引出從句, 全句可譯為:“以后?才”、“?然后才”、“?(之后)才” 1.It will be months before he is fit for the job.還得幾提示: 個月之后，他才能適應這項工作。2.We waited five hours before the runway was cleared of heavy snow and made ready for take-off.我們足足等了5個小時，才有人清掃完跑道上的積雪，準備好飛機起飛。17.

第四篇：北郵網(wǎng)院英語答案

一、閱讀理解（共1道小題，共25.0分）?

William Henry Harrison, the ninth President of the United States, was born in a small town.As a boy, he was quiet and shy.In fact, he was so quiet that everyone thought he was stupid.Because of that, the people of the town liked to play jokes on him.“Here, William,” one of them would say.“Here is a nickel(五美分硬幣), and here is a dime（十美分硬幣）.Which one do you want?” He always chose the nickel, and then they all laughed at him.Finally, his mother took him aside and said to him, “I know that you are a smart boy, but sometimes you let people think you are not so smart.Why do you always choose the nickels instead of the dime? Don't you know that a dime is worth much more than a nickel?”

“Certainly, I know it,” William answered slowly.“But if I choose the dime, they won't play the trick on me any more.Then I won’t get any more nickels.”

William Henry Harrison was born_____.? ? ? ? in a big city on a farm in the countryside in a small town People thought he was stupid because ______.? ? ? ? he did poorly at school he was so quiet he always asked foolish questions he was afraid of others Whenever people played tricks on him, he was asked to_____.? ? ? ? laugh at himself make faces choose between a nickel and a dime tell right from wrong His mother took him aside and asked why _____.? he always chose the nickel instead of the dime ? he didn’t know that a dime was worth more than a nickel ? people played the same trick on him ? he failed to let people know how smart he was We can infer from the story that William Henry Harrison was ______.? ? ? ?

試題分值：25.0 得分：[5, 5, 5, 5, 5] ? 提示：[1]D.細節(jié)題。本題問“William Henry Harrison出生于______?！敝行脑~是“was born”，答案在第一段的第一句，該句告訴我們William出生于一個小鎮(zhèn)，所以答案是D。

[2]B.細節(jié)題。本題問“人們認為他非常笨，這是因為_______?！敝行脑~是“thought he was stupid”，答案在第一段的最后一句，該句大意是“當他還是個孩子的時候，他不喜歡說話而且很害羞。實際上，他是如此的安靜以至于別人都認為他很笨”。據(jù)此可知答案是B。[3]C.細節(jié)題。本題問“每當人們想和他開玩笑的時候，人們就讓他_______?！敝行脑~是“played tricks on him”，答案在第二段和第三段，只不過第二段中出現(xiàn)的是“play jokes on him”，這兩個詞組意思相近。第二段大意是“就因為這個，所以人們喜歡開他的玩笑?！钡谌蔚拇笠馐恰坝腥藭f：‘過來，William。這里有一個5美分硬幣和一個10美分的硬幣。你想選擇哪一個？’”根據(jù)這兩段，我們可以知道答案是C。[4]A.細節(jié)題。本題問“他媽媽將他帶到一旁問他為什么_______?！贝鸢冈诘谖宥危摱未笠馐恰白詈?，他媽媽將他帶到一旁對他說道：‘我知道你是個聰明的孩子，但是有些時候你讓別人覺得你不是那么聰明。為什么你總是選擇5美分的硬幣而不選擇10美分的呢？難道你不知道10美分的硬幣比5美分的值錢嗎？’”據(jù)此可知答案是A。

[5]D.推斷題。本題問“從故事中我們可以推測出William Henry Harrison是______?！贝鸢冈谧詈笠欢危摱未笠馐恰癢illiam慢慢地回答道：‘我當然知道。但是，如果我選擇了10美分的硬幣，他們就不會再和我開玩笑了。這樣的話，我就再也得不到5美分的硬幣了?！睋?jù)此可知答案是D（聰明的）。
