A. has been bought     B. will be bought     C. is bought    D. was bought

【答案】D

【解析】考查動詞時態。本題容易錯選A項。語境有具體過去時間“half a year ago”,因此buy表示過去的動作,用一般過去時被動語態。

3. “I       in the room, watching TV broadcast about the earthquake.” I told the policeman who had driven here to question me.

A. was staying     B. stay       C. stayed          D. am staying

【答案】A

【解析】考查動詞時態。語境沒有提到具體時間,但從語境和和試題命制形式上看是直接引語,這里表示回答警察的訊問,那么一定是問在過去某個時候“我”在做什么,因此用過去進行時。

A. which        B. that        C. where          C. that whenever

【答案】 D

【解析】考查表語從句和狀語從句。從語境看,本題需要兩個連接詞,一個是表語從句的連詞that,此時that只起連接作用,不在從句中做任何成分,而且一般不省略;表語從句中還有一個狀語從句,表示“無論他在什么時候出現”,用從屬連詞whenever。

A. who; should turn                B. whom; shall turn

C. whomever; turns                D. whoever; turn

【答案】 A

Human beings have always been fascinated by twins. Romulus and Remus, Jacob and Esau, Mary-Kate and Ashley.

As children, many of us imagine having a twin: a permanent playmate, a partner in trouble, someone who’d love us unconditionally. Somewhere out there is someone who is exactly like us! What would it feel like to look into a face exactly like our own?

And what if she suddenly appears in my life? That’s essentially what happened to Brooklyn writer Paula Bernstein. I’d known Paula slightly for years; she wrote a lovely essay for Redbook many years ago refuting(駁斥) the persistent belief that all adoptees want to search for their birth parents. Her adoptive family was her family, she wrote; her adoptive mother was her mother. But then, out of the blue, an adoption agency called her and told her about the identical twin sister she didn’t know she had. Her sister, Elyse Schein, wanted to meet her.

I met them for coffee at Café Mogador, three years after their first meeting. Now 38, they have different haircuts, have made different choices in hair color, do their makeup differently. But they clearly look alike, with thick hair, upturned noses. They quickly discovered they had the same childhood habit of sucking their middle fingers, the same adult habit of forgetfully typing their thoughts on an invisible keyboard while thinking. Both edited their high school newspapers and studied film in college. Paula wrote film criticism; Elyse became a filmmaker. They both collected Alice in Wonderland dolls and kept them in the boxes.

They’re now regulars at Café Mogador. The women’s journey from strangers to sisters has clearly been rocky. But as they got to know each other, and struggled to piece together their history, their search united them.

“For me, the search began when I reached the age when my adoptive mother died,” Elyse said. “I realized that my birth mother could be dead. Time was passing. I was ready to solve the mystery that had shadowed my life.” Elyse had always felt a part of her was missing. “I’d felt so different from my adoptive family.” she said.

Paula was raised in a more typical Jewish intellectual family, and was at first a little threatened by Elyse’s appearance in her life. “My first response was both fear and excitement. The moment we met, I felt I was meeting my long-lost best friend. I could tell her anything. And then as that first excitement wore off, I thought, oh my God, I’ve committed to a long-term relationship with a stranger. I wished we hadn’t been separated, but also that I hadn’t been contacted. What would it mean to be in each other’s lives?”

5. What is the main idea of the passage?

A. We always hope to have twins for much good.   

B. We are often attracted by twins because of the mystery.

C. The long-lost twins, Paula and Elyse, were reunited.

D. Life with twins is always wonderful.

6. Which of the following can we infer is the least common names of twins according to the passage?

A. Romulus and Remus.                             B. Jacob and Esau.

C. Mary-Kate and Ashley.                          D. Paula and Elyse.

7. The underlined words “out of the blue” in the fourth paragraph can be replaced by ________.

A. unexpectedly        B. accidentally       C. oppositely             D. out of control 

8. It can be inferred that the following paragraph of the passage will talk about _________.

A. how Paula and Elyse found each other

B. how Paula and Elyse were separated when young

C. what their mothers were like

D. their mixed feelings when they saw each other

                                                   C

Tess still stood hesitating like a swimmer about to make his dive, hardly knowing whether to return or move forward, when a figure came out from the dark door of the tent. It was a tall young man, smoking.

He had an almost black face, though red and smooth. His moustache was black with curled points, though he could not be more than twenty three or―four. There was an unusual force in his face, and in his daring rolling eyes.

“Well, my beauty, what can I do for you?” said he, coming forward. And seeing that she was quite at a loss, “Never mind me. I am Mr. d’Urberville. Have you come to see me or my mother?”

This differed greatly from what Tess had expected. She had dreamed of an aged and dignified face. She tried to keep calm and answered― “I came to see your mother, sir.”

“I am afraid you cannot see her―she is ill in bed,” replied the representative of the house; for this was Mr. Alee, the only son of the noble family. “What is the business you wish to see her about?”

“It isn’t business―it is―I can hardly say what!”

“Pleasure?”

“Oh no. Why, sir, if I tell you, it will seem…”

Tess’s sense of a certain ridicule was now so strong that, despite her general discomfort at being here, her rosy lips curved(彎曲) towards a smile, much to the attraction of the young man.

“It is so foolish”, she stammered(急急巴巴地說). “I fear I can’t tell you!”

“Never mind; I like foolish things. Try again, my dear,” said he kindly.

“Mother asked me to come,” Tess continued; “and, indeed, I was in the mind to do so myself. But I did not think it would be like this. I came, sir, to tell you that we are of the same family as you.”

“Ho! Poor relations?”

“Yes.”

“Stokes?”

“No; d'Urbervilles.”

“Ay, ay; I mean d'Urbervilles.”

“Our names are worn away to Durbeyfield; but we have several proofs that we are d'Urbervilles. The local scholars hold the view that we are, and…and we have an old seal(印章) and a silver spoon marked with the same castle as yours. So mother said we ought to make ourselves known to you, as we’ve lost our horse by a bad accident; we can hardly make a living.”

   “Very kind of your mother, I’m sure.” Alec looked at Tess as he spoke, in a way that made her uneasy. “And so, my pretty girl, you’ve come on a friendly visit to us, as relations?”

“I suppose I have,” looking less confident and uncomfortable again.

“Well―there’s no harm in it. Where do you live? What are you?”

                                    ―-Tess of the d'Urbervilles By Thomas Hardy

9. How does Tess feel in the whole course of the meeting with Alec?

A. Excited and hopeful.                 B. Nervous and uncomfortable.

C. Surprised but comfortable.              D. Pleased but embarrassed.

10. In the eyes of Tess, Alec is _______________.

A. forceful and daring                  B. unfriendly and talkative

C. a gentle and reliable man              D. older than she had expected

11. Why does Tess pay the visit to the d'Urbervilles?

A. To see Alec himself.                  B. To see Alec’s mother.

C. To confirm that they are of the same family.

D. To make known their relationship and seek help.

12. Alec appears quite friendly to Tess mainly because __________.

     A. Tess is his distant relation                B. Tess looks polite to him

     C. Tess is a pretty girl                            D. Tess looks ridiculous

    Get a reward for every bug you bring to live in new science museum exhibit.

In a city with trillions of American cockroaches(蟑螂), the Houston Museum of Natural Science has agreed to pay a quarter per bug-up to 1,000-as it seeks to populate a new insect exhibit alongside its Cockrell Butterfly Center.

Nancy Greig, the museum’s director insists the public payday for roaches isn’t just a marketing ploy(炒作).

“Absolutely, this wasn’t devised as a joke,” Greig said. “We needed more roaches for the exhibit, so I sent this message out to everyone in the museum asking people to bring them in. Well, someone decided to tell the press, and all hell has broken loose.”

“But we really do need cockroaches.”

“One might be forgiven for never considering how to catch a live cockroach. But it’s simple enough to fool them,” Greig said, “and even easier to catch them.” American cockroaches are the most common kind in Texas, measuring up to 2 inches long and invading homes.

Despite their less-than-attractive reputation, cockroaches actually aren’t that dirty. Greig even went so far as to call them “fastidious” saying they don’t enjoy rooting(用嘴拱食) in waste. They’re only dirty if, say, they used a sewer(下水道)line to gain access into a home.

The roaches collected by the museum will become part of a display in a new exhibit that showcases insects such as cockroaches, dung beetles and termites.

There’s more to like about roaches, too. They don’t bite, and they don’t carry diseases like a mosquito, so they’re generally safe to handle.

13. For what does the museum pay for cockroaches?

A. For a marketing ploy.       B. It’s devised to make fun.

C. People really need them.     D. For a new exhibit.

14. The underlined word “fastidious” probably means extremely ________.

A. clean     B. dirty     C. unpleasant     D. fast                    

15. What do we know about American roaches?

A. It’s not easy for people in Houston to collect roaches.

B. They all measure 2 inches and are often found in homes

C. They don’t bite and they are free of disease.

D. We have reasons to like them.

16. Which of the following can serve as the best title for the passage?

A. The Houston Museum of Natural Science            B. A new exhibit

C. Quarters for cockroaches                        D. A cockroach is lovely

                                                        E

   Is a loved one missing some body parts? Is everyone at your dinner table of the same species? Humans and chimps(黑猩猩)differ in only 400 genes. And should that worry us ?Is it horrible for you thinking one fifth of all our genes are owned by someone else, or a person and his family may be hunted cross-country because they happen to have certain valuable genes? We live in a time of great scientific leaps!

   Next challenges our sense of reality, blending fact and fiction into a breathless tale of a new world where nothing is what it seems.

   The son of a zookeeper, 16-year-old Pi Patel is raised in Pondicherry. India. Planning a move to Canada, his family takes a ride on an enormous ship. After a shipwreck。Pi finds himself in the Pacific Ocean, trapped on a 26-foot lifeboat with a wounded zebra, a hyena(鬣狗), a orangutan(猩猩), and a tiger named Richard Parker It sounds like a colorful setup. But these wild animals don’t burst into song as in the Disney cartoons. All want to survive, however Pi finds himself the weakest one of all. After much infighting, Pi and Richard Parker remain the boat’s only passengers. Pi is left to survive for 227 days through waters with his large dangerous companion, using all his knowledge, wits and faith.

【答案解析】 

A篇:本文介紹一個很有創意的網站:FreeRice.com,游戲者只要選對一個單詞的釋義,就可以為饑民掙得20粒米,廣告商和贊助商通過聯合國機構為饑民捐獻大米。

1.A考查細節理解。文章羅列的在FreeRice玩英語詞匯游戲的各種好處,沒有提到A項。

2.B考查推理判斷。在“FreeRice節目如何工作”一節,作者提到該游戲能根據游戲者的答題情況自動調節詞匯的難度,因此適合各種人群參與。

3.D考查主題大意。從文章的敘述看,這個網站的目的是將學習英語詞匯與捐大米給饑民結合起來。

4.C考查推理判斷。從文章開頭的FreeRice.com和WARNING后的more判斷,本文出自網站。

B篇導讀:本文的話題是雙胞胎。全文講述一對雙胞胎的故事:她們被不同家庭收養,但是在各自的家庭感覺與家庭其他人不一樣,其中一人在養母去世后開始尋找自己的雙胞胎姐妹,她們相遇后發現她們有太多的相同方面,無論個人喜好還是人生經歷。

5.C考查主旨要義。本文在談論雙胞胎這個話題后,重點講述美國布魯克林作家Paula和其雙胞胎Elyse在養母去世后重逢的故事,因此本文的主題應該選C。

6.D考查推理判斷。第一段說,人們總被雙胞胎所吸引,比如Romulus and Remus, Jacob and Esau, Mary-Kate and Ashley。從這些內容判斷,A、B、C都是創建的雙胞胎的名字,而D項是本文故事的主人的名字,屬個例,因此本題選D。

7.A考查猜詞悟義。從語境判斷,劃線部分的含義是A,突然,出乎意料之外地:對于被收養者總在尋找自己的生身父母的說法她嗤之以鼻,可是“突然”一家收養者機構對她說,她的雙胞胎姐妹在找她。這突如其來的消息駁斥了她的觀點。

8.B考查推理判斷。關于這對雙胞胎,本文采用倒敘的方式,先講這對雙胞胎的重逢故事,然后說她們各自在不同的收養家庭長大,那么下文就應該講述她們當初被別人收養的背景。

C篇導讀:本文選自哈代的《德伯家的苔絲》。從貧窮鄉下來的苔絲想到德伯家來認親戚,見到富親戚家的公子Alec,在和Alec的交談中她一直覺得緊張不安。

9.B從文章的敘述看,從貧窮鄉下來的苔絲想到德伯家來認親戚,在和Alec的交談中她一直覺得很緊張,很不自在。

10.A文章第二段說苔絲覺得對方的臉上帶有不同尋常的力量,眼睛中帶有大膽的成分,第四段說,苔絲本希望遇到的是一個年老而高貴的臉孔。

11.D文章說到苔絲此行的目的:“來告訴你們,我們是同一個家族,我們幾乎難以生存”。顯然她來此的目的是D。

12.C文章最后部分,Alec對苔絲說,“那么,美麗的姑娘,你到我們這里來是作為親戚來看望我們的?”由此判斷本題選C,Alec覺得苔絲美麗而和她搭訕。

D篇:本文是媒體報道,關于一家博物館的新展覽。某博物館為了一項新展覽的需要,出錢向公眾購買蟑螂。

13.D考查細節理解。從文章的敘述可知,博物館出錢購買蟑螂是為了一項新展覽的需要。其他選項在文章中直接批駁了。

14.A考查猜測詞義。第七段說,Greig甚至把它們稱為 “fastidious”,它們不在骯臟的地方拱食,僅僅在進入居家的路程中從下水道經過時才弄臟了。由此判斷,該詞的含義與下文提到的dirty相反,因此選A,他認為蟑螂本來是很干凈的動物,卻被人們誤認為很臟。

15.D考查推理判斷。文章最后一段第一句說“蟑螂還有其可愛之處”,接著提到蟑螂的可愛和安全方面,因此選D。B與文中up to 2 inches矛盾, C項說“蟑螂沒有疾病”,這是文中未提及的內容。

16.C考查主題大意。本文介紹美國一家博物館的新展覽,他們向人們購買蟑螂,考慮新聞報道的時效性和標題的引人入勝,本文應該選C做標題:購買蟑螂的價格,以吸引讀者繼續閱讀這篇新聞。 A顯然錯誤。B項作為標題范圍過大,本文只講了腐蝕性昆蟲展中的部分內容(收集的蟑螂)。C既體現了主體內容:收集蟑螂,又兼顧了新聞標題 的特點,適合作為標題。

E篇:本文是一則廣告,介紹幾本書的內容。

17.C考查猜測詞義。劃線詞的語境說,該書挑戰我們的現實感,將事實與科幻blend成一個故事新世界,由此判斷其含義是C,“聯合,結合”。

18.C這是第二則的內容,說派來到太平洋海底,和其他動物為伍,所有動物都想活命。

19.D考查推理判斷。該書的介紹說,這本書探索“來生”的神秘,提醒我們,重要的是今天,由此判斷該書的主題是D,了解生活的真諦。

20.A考查推理判斷。最后一句說,在小說的餓結尾,Grogan談到Marley給他的啟迪,由此判斷,Grogan是該書的作者。

2)時文閱讀

   BEIJING (Reuters) - Dozens of young Chinese, angry at disruption of the Olympic torch relay in Paris, protested outside a Carrefour branch in east China on Friday, setting fire to a French flag, waving banners and shouting slogans, local media said.

   There have been small protests at the French retail giant's stores in several Chinese cities, including Beijing, in the past week, but the latest outburst in the eastern coastal city of Qingdao came after state media moved to cool down the nationalistic fervor.

   Chinese Internet users are calling on consumers to boycott Carrefour, which they accuse of supporting pro-Tibetan independence groups seeking to disrupt this year's Beijing Olympics.

   The journey of the Olympic torch around the world has been dogged by protests, largely over Chinese rule in Tibet, where a wave of anti-government unrest erupted in March.

   In Paris, numerous protests and attempts by activists to snatch the torch prompted Chinese security officials to extinguish the torch several times and put in on a bus.

   Local media photos showed the protesters holding up banners that read "Boycott France, Support the Olympics" and "Oppose Tibet independence, Love the motherland".

   They waved red Chinese flags and shouted slogans, attracting a big crowd of onlookers. One photo showed a man burning a French flag.

   Chinese Internet message boards have also featured photos from Hefei, capital city of the eastern province of Anhui, where several "elementary school students" staged a protest with a banner reading "Oppose Carrefour, Shopping is shameful".

   France has tried to play down calls for a boycott of French goods, saying they were being made by a "very small minority" and Carrefour, which has more than 100 hypermarkets in China, has restated its support for Beijing's hosting of the Olympics. Some Chinese newspapers have also run commentaries against the boycott, saying in the era of globalization it would only hurt Chinese employees and suppliers.

   Still, an opinion poll in 10 Chinese cities found 66 percent of respondents supported the Carrefour boycott, according to the official Xinhua news agency. Only 7 percent said outright that they would not.

Questions:

1. What is the best title of the passage? (Please answer within 10 words.)

   ________________________________________________________________________

2. Why are Chinese Internet users calling on consumers to boycott Carrefour? (Please answer within 30 words.)

________________________________________________________________________

3. What is the result of the opinion poll conducted in 10 Chinese cities? (Please answer within 10 words.)

   ________________________________________________________________________

【答案解析】

1. Angry Chinese burn French flag outside Carrefour
2. Because they accuse Carrefour of supporting pro-Tibetan independence groups seeking to disrupt this year's Beijing Olympics.

3. 66 percent of respondents supported the Carrefour boycott.

書面表達范文 (One possible version)

    Hello, everyone,

Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.

As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.

書面表達范文 (One possible version)

This form displays the result of a survey on how to spend students’ weekend. It says that few students are glued to their schoolwork any more. Instead, they prefer to surf on the internet, watch TV, go shopping rather than involve in sports games. Library and interest groups are available but not favourable.

Personally I think, students are now freed from heavy burden but their spare time is not well arranged. They are expected to spend some time on what they learn instead of hanging out. More time should be spent not only on green field but also in the libraries to build up themselves physically and mentally. Besides, more interest groups should be established for students to widen their horizon and sharpen their brains so that they can become more creative eventually. All these will contributes a lot to a well-informed and highly qualified teenagers.

In conclusion, students should be more scheduled with colorful and fruitful activities.

書面表達范文 (One possible version)

I am Li Ming of Senior Three, Guangming Middle School. I am writing to tell you about some symptoms of anxiety among us students before exams.

Most of us feel nervous whenever we’re taking an important exam. Some will feel dizzy or tired, some will suffer from lack of sleep, and some will lose their appetite. In fact, all these symptoms have terrible effects on our exams and we are all eager to get rid of them.

First of all, in my opinion, it’s important for us to have a fight attitude towards exams. They are only a means of checking how we are getting along with our studies, so there is no need to worry too much about the results. Study hard every day and make careful plans for every exam. In this way we can avoid suffering from the pressure of exams.

Besides, enough sleep can make us energetic and enable us to perform well in an exam. Therefore, during the period of exams, we should not stay up too late. We can also try a warm bath or a cup of warm milk before going to bed. They might help us to have a sound sleep.

(We’d better go out for a walk or do some outdoor exercises before and during an exam so that we can keep ourselves relaxed and then concentrate ourselves on exams.)
