第一篇:2015北郵遠(yuǎn)程教育大學(xué)英語階段2作業(yè)
一、閱讀理解(共1道小題,共25.0分)
1.One day in 1965, when I was a library worker at school, a teacher came to me.She had a student who finished his work before all the others and needed something more difficult for him to do.“Could you help me in the library?” she asked.I said, “Send him along.”
Soon, a golden-haired boy appeared.“Do you have a job for me?” he asked.I told him about a system for sorting books.He picked up the idea immediately.Then I showed him some cards for some unreturned books that though had been returned but not recorded.Maybe some books were put on wrong places.He said, “Is it a kind of a detective job?” I answered yes, and then began his work.He had found three books with wrong card by the time his teacher opened the door and said, “Time for rest!” he argued for finishing the finding job, but the teacher won.The next morning, he arrived early, “I want to finish these books,” he said.At the end of the day, when he asked to work with me more often, it was easy for me to say yes.After a few weeks I found a note on my desk, inviting me to dinner at the boy’s home.At the end of a pleasant evening, his mother declared that the family would be moving to another school area.Her son’s first concern, she said, was leaving the library.“Who will find the lost books?” he asked.When the time came, it was hard to say goodbye.Though at the beginning he had seemed an ordinary boy, his strong feeling of interest had made him different.Do you know who he is? This boy became a great man of the information age: Bill Gates.2.1.Why did the teacher go to the library to find a job for Bill Gates?
2.1.2.3.4.Because the teacher found the librarian quite busy.Because Bill Gates wanted to find a job.Because Bill Gates finished his study quickly and had more free time than the others.Because the library needed a new worker.3.What do you know from the passage?
4.1.2.3.4.Library work was very difficult for Bill Gates.Bill Gates did his job without any difficulty.The librarian was too busy to have a rest.His mother hoped that Bill Gates would stay for his job.1.The sentence “He picked up the idea immediately” means that_____.2.1.2.3.4.he learned that system quickly he collected that system quickly he lifted up that system quickly he improved that system quickly 1.What was Bill Gates expected to do in the library?
2.1.2.3.4.Finding the lost cards.Learning the system.Helping the worker with everything in the library.Finding books with wrong cards.1.How did Bill Gates feel when his family would move to another school area?
2.1.2.3.4.Sad.Pleasant.Worried.Interested.試題分值:25.0
得分:[5, 5, 5, 5, 5] 提示:[1]C.細(xì)節(jié)題。本題問“為何那位老師要去圖書館給Bill Gates找工作?”中心詞是“the teacher”和“the library”。答案在第一段的第二句,該句大意是“She had a student who finished his work before all the others and needed something more difficult for him to do.這名老師有一個(gè)學(xué)生,這個(gè)學(xué)生比別的學(xué)生提前完成功課,需要找一些難一點(diǎn)的事情來做?!睋?jù)此可知答案是C。
[2]B.中心思想題。本題問“你從文章中可以得知什么?”解決這種題目,我們首先要瀏覽一下選項(xiàng)的大意。A的意思是“對Bill Gates來說,圖書館的工作太難了?!盉的意思是“Bill Gates毫不困難地就完成了圖書館的工作?!盋的意思是“那名圖書管理員太忙了,都沒有時(shí)間休息?!盌的意思是“Bill Gates的母親希望他能夠留下來繼續(xù)做這份工作。”接著,我們要對每一個(gè)選項(xiàng)進(jìn)行判斷。第二段的第四句話告訴我們,Bill Gates很快就領(lǐng)會(huì)了那位圖書管理員的意思。據(jù)此可見A是錯(cuò)誤的,B是正確的。文章并沒有說那名圖書管理員忙得都沒法休息,所以C是錯(cuò)誤的。文章的倒數(shù)第二段告訴我們,Bill Gates一家都要搬到外地,Bill Gates的媽媽并沒有要求兒子獨(dú)自留下來。據(jù)此可知D也是錯(cuò)誤的。
[3]A.句義理解題。本題問我們“He picked up the idea immediately ”這句話是什么意思。A的意思是“他快速的學(xué)會(huì)了圖書館的系統(tǒng)。”B的意思是“他快速的收集了圖書館的系統(tǒng)?!盋的意思是“他快速地舉起了圖書館的系統(tǒng)。”D的意思是“他快速地改善了圖書館的系統(tǒng)?!?根據(jù)上面第二題的解釋,我們已經(jīng)知道這個(gè)句子的意思是A。
[4]D.細(xì)節(jié)題。本題問“Bill Gates在圖書館里要做什么事情?”中心詞就是“the library”,經(jīng)過定位我們會(huì)發(fā)現(xiàn)答案在第二段。該段中間幾句大意是“我又給他看了一些未歸還書的書卡,其實(shí)這些書已經(jīng)還回來了,但是當(dāng)時(shí)并沒有做記錄。也許其中一些被放在錯(cuò)誤的地方了?!睋?jù)此,可知答案是D(Bill Gates要利用這些書卡找到那些書。)
[5]C.細(xì)節(jié)題。本題問“Bill Gates對于自己家要搬到另一個(gè)校區(qū)有什么感受?”中心詞是“another school area”。答案在倒數(shù)第二段,該段大意是“幾周之后,我在辦公桌上發(fā)現(xiàn)了一張紙條,孩子一家邀請我去共進(jìn)晚餐。在共度了一個(gè)美好夜晚之后,孩子的母親告訴我說他們一家將會(huì)搬到另一個(gè)校區(qū)。她說孩子最關(guān)心的就是要離開圖書館了。孩子會(huì)問,‘誰來找那些丟失的書呢?’分手時(shí),我們真的是難舍難分。雖然在開始的時(shí)候,這個(gè)孩子似乎很平常,但是他做事情的那種強(qiáng)烈的興趣使得他與眾不同。”據(jù)此可見Bill Gates的感覺是C(擔(dān)憂的)。

2017北郵網(wǎng)院大學(xué)英語2精讀(三階段作業(yè))
一、閱讀理解(共1道小題,共25.0分)
1.A pretty, well―dressed young lady stopped a taxi in a big square, and a said to the driver, “Do you see that young man at the other side of the square?”
“Yes,” said the taxi driver.The young man was standing outside a restaurant and looking impatiently(不耐煩地)at his watch every few seconds.“Take me over there,” said the young lady.There were a lot of cars and buses in the square, so the taxi driver asked, “Are you afraid to cross the street?”
“Oh, no!” said the young lady.“But I promised that I would meet the young man for lunch at one o' clock, and it is now a quarter to two.If I arrive in a taxi, it will at least seem as if I had tried not to be late.” 1.How did the young woman get to the square? A.She arrived in a taxi.B.She drove there in a car.C.She got there by bus.D.The story doesn't tell us.2.Why did the lady stop the taxi? A.Because she didn't want to be late for her appointment(約會(huì)).B.Because she wanted to get out of the taxi.C.Because she wanted to go to the restaurant in it.D.Because she was afraid of walking across the street.3.The young man at the other side of the square_______.A.had probably been waiting for a long time B.had some problem with his watch C.was probably a waiter of the restaurant D.was someone the young lady didn't want to see 4.The young lady was_______.A.clever at making excuse B.not late at all C.45 minutes earlier D.15 minutes late 5.Had she tried not to be late? A.Yes, she had tried her best.B.No, she was just pretending that she had tried.C.Yes, she had tried but she was still late.D.No, she thought being late was better than being early.試題分值:25.0 得分:[5, 5, 5, 5, 5] 提示:[1]D.細(xì)節(jié)題。本題問“這個(gè)年輕女性是如何到達(dá)廣場的?”瀏覽文章后,我們并沒有找到相關(guān)內(nèi)容,所以答案是D(文章沒有告訴我們)。[2]C.細(xì)節(jié)題。本題問“為何這名女士要攔住那輛出租車?”答案在第三段,該段告訴我們這名女士想搭乘出租車到廣場附近的一個(gè)飯店。據(jù)此可知答案是C。
[3]A.推斷題。本題問“廣場另一邊的那個(gè)男青年______?!贝鸢冈谧詈笠欢?,該段大意是“女士說道:‘哦,不是的。我本來答應(yīng)在中午1點(diǎn)鐘的時(shí)候和那個(gè)男士一起吃午餐的,但是現(xiàn)在已經(jīng)是1點(diǎn)45分了。如果我乘坐出租車趕到那里的話,這至少顯得我在盡力避免遲到?!睋?jù)此可以推測答案是A(很可能等待很長時(shí)間了)。[4]A.推斷題。本題問“這名女青年_______。”先瀏覽選項(xiàng)。A的意思“很善于編造理由”,B的意思“根本沒有遲到”,C的意思是“早到了45分鐘”,D的意思是“遲到了15分鐘”。本題答案明顯是A。
[5]B.推斷題。本題問“這名女青年又沒有盡力不遲到?”根據(jù)第三題的解釋,我們可知這名女青年只是在假裝避免遲到,所以答案是B。

[3]A.考查句意理解和常識。本句意思是“希望6個(gè)月大的時(shí)候開始吃竹子嫩芽和______?!痹倏催x項(xiàng)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(gè)_______年輕熊貓,重達(dá)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(dāng)希望20個(gè)月大的時(shí)候,她就不得不照看自己了,______她媽媽又生了個(gè)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。

[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(huì)遇到的______。”很明顯空格處的意思是“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(shí)指較嚴(yán)重的問題,所以是需要“解決”(solve,work out)的。本句中指的是熊貓?jiān)谏钪杏龅降目陀^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(xiàng)的意思是:cut down(砍伐),plant(種植),protect(保護(hù)),water(澆水)。顯然,此處應(yīng)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(huì)帶走這些熊貓寶寶。人們會(huì)認(rèn)為這些寶寶需要_______?!彼膫€(gè)選項(xiàng)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?!癲o
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(xué)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(gè)詞組相當(dāng)于一個(gè)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(dāng)?shù)氐闹参镏?,這座花園還有無數(shù)來自海外的花草樹木。
In addition相當(dāng)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(dāng)?shù)刂参锏淖罴颜洳?。另外,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(diǎn): Choice3

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(dòng)詞原形”表示“寧愿”,是英語中常見的一個(gè)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(gè)情態(tài)助動(dòng)詞,且無詞性、時(shí)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(dú)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(diǎn)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(jìn)行取舍,表示“寧愿??而不愿??,與其??寧可??”的意思時(shí),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(yīng)跟不帶to的動(dòng)詞不定式。
