Several recent studies have found that being randomly assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood of conflict.

    Recent reports found that lodging with a student of a different race may decrease prejudice and compel students to engage in more ethnically diverse friendships.

    An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.

    In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove."

    Researchers also observed problems resulting from pairing interracial students in residences.

    According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.

    An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.

    Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said.

    At Penn, students are not asked to indicate race when applying for housing.

    "One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration."

    "I've experienced roommate conflicts between interracial students that have both broken down stereotypes and reinforced stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also "jarring cultural confrontations."

    The RA said that these conflicts have also occurred among roommates of the same race.

    Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.

1.What can we learn from some recent studies?

  A. Conflicts between students of different races are unavoidable.

  B. Students of different races are prejudiced against each other.

  C. Interracial lodging does more harm than good.

  D. Interracial lodging may have diverse outcomes.

2.What does Sam Boakye's remark mean?

  A. White students tend to look down upon their black peers.

  B. Black students can compete with their white peers academically.

  C. Black students feel somewhat embarrassed among white peers during the        freshman year.

D. Being surrounded by white peers motivates a black student to work harder to succeed.

3.What does Alec Webley consider to be the "definition of integration"?

   A. The school randomly assigns roommates without regard to race.

   B. Students of different races are required to share a room.

   C. Interracial lodging is arranged by the school for freshmen.

   D. Lodging is assigned to students of different races without exception.

 

【答案】

 

1.D

2.D

3.A

【解析】文章介紹了在大學中沒有按照種族來劃分宿舍,帶來的種種后果。

1.D 細節題。根據第一段第二行can lead to increased tolerance but also to a greater likelihood of conflict.以及在后兩段中所舉之例說明這樣做既有優點也有缺點,會有很多不同的結果,故D正確。

2.D 推理題。if you're surrounded by whites, you have something to prove.這句指在白人的包圍下,黑人需要證明自己的能力,這樣就激發了黑人更努力來取得成功,故D正確。

3.A 細節題,根據文章倒數第四段One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly,"說明學校沒有考慮種族就胡亂分配宿舍是definition of integration的定義。

Hi, dear boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.

It's a name that needs no address.Everyone knows Santa Claus lives at the North Pole.

So letters sent to Santa Claus find their way to the small town of the North Pole deep in Alaska,including those simply sent to Santa. Last year,120,000 letters arrived from 26 countries,not including the thousands with no return addresses.

Those who have return addresses usually get a reply and a North Pole postmark(郵戳) that has delighted children all over the world for many years. They feel happy to receive Santa's reply.

Letters arrive all the year around in the town of 1,600,where streets have names such as Santa Claus Lane and Kris Kringle Drive. Around Thanksgiving,they start getting there by the thousands each day as Christmas comes. Even letters without stamps get through,an exception(例外)for the U.S. Postal Service.

“This is special because it has Santa's name on it,”said Debra Cornelius,an officer at the main post office in nearby Fairbanks,where the letters are kept during the holiday.

Gabby Gaborik is among several dozen volunteers who are busy sending off replies to children who sent return addresses.

In his 10 years as a volunteer,Gaborik has seen every kind of wish. There are children who want the latest toys they see on TV. There are children who ask for miracles(奇跡),some wanting their mother back for Christmas or their father back from Iraq,even though he died there.

Replies get a North Pole postmark,including a half­moon drawing of Santa's face. Even late letters get a reply,Gaborik said,“It says something like ‘Thanks for writing. Santa's been really busy,’anything the children might want to hear,”he said.

1.Letters written to Santa Claus without an address can arrive at the North Pole because ______.

A.all letters without an address are sent there

B.people believe that Santa Claus lives there

C.this kind of letter is sent with a special postmark

D.streets named Santa Claus Lane can be found there

2.The underlined word “delighted” in Paragraph 3 can be replaced by “______”.

A.excited               B.amazed                 C.confused            D.disappointed

3.We can know from the text that ______.

A.letters written to Santa Claus are sent free

B.Santa Claus' replies to children always arrive at Christmas

C.many people write to children for Santa Claus asking for no pay

D.there're thousands of letters sent to Santa Claus every month

4.What's the best title for the text?

A.Letters written to parents

B.All kinds of wishes from children

C.Letters to Santa Claus rush into Alaska

D.North Pole,Alaska,a beautiful place

The other day I heard a few local musicians talking, "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm (韻律).""Nobody wants to pay musicians anything. I’m sick of all the people who want you to play without paying you.” One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I’m trying to find other places to play. I’m also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him.

Attitudes are important. Whether they’re positive or negative (消極的), they’re all rubbing off on you. If you’re around people who are always complaining(抱怨) or blaming (責備) others, it is possible that you will start doing the same as well. If you spend lots of time with people who don’t support your dreams, it is time to take a look at the people you call "friends".

There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.

1.The musicians’ conversation at the beginning is to show that ______.

A.musicians’ living conditions are not good

B.people in that town have poor taste in music

C.different people have different attitudes

D.young people are more likely to succeed

2.The underlined part "they’re rubbing off on you" in Paragraph 2 means ______.

A.they’ll push you ahead

B.they’ll have an influence on you

C.they’ll keep you from moving on

D.they’ll help you realize your dreams

3.Why did the author want to make friends with the younger musician?

A.He is more active than the others.

B.He can earn more than the others.

C.He has more things to do than the others.

D.His attitude is more positive than the others.

4.By doing the exercise mentioned in Paragraph 3, you can ______.

A.make the right kind of friends

B.improve your ability to make friends

C.develop a better relationship with your friends

D.make some new friends with the same interests as you

科目:高中英語 來源:2010-2011學年重慶市高三上學期第一次月考英語卷 題型:閱讀理解

    We can see how the product life cycle works by looking at the introduction of instant(速溶) coffee. When it was introduced, most people did not like it as well as "regular" coffee, and it took several years to gain general acceptance(introduction stage).At one point, though, instant coffee grew rapidly in popularity, and many brands were introduced(stage of rapid growth). After a while, people became attached to one brand and sales leveled off(stage of maturity). Sales went into a slight decrease when freeze-dried coffees were introduced(stage of decline).

    The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not drop. One strategy is called market modification. It means that marketing managers look for new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the soldiers?

    Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.

    Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to regain world markets. Note, also, how auto manufacturers once changed styles eagerly from year to year to keep demand from falling.

1.The first paragraph tells us that a new product is ________.

       A.not easily accepted by the public

      B.often of poorer quality compared with old ones

       C.often more expensive than old ones

      D.usually introduced to satisfy different tastes

2.Marketers need to know which of the four stages a product is in so as to________.

       A.promote its production

      B.work out marketing plans

       C.speed up its life cycle

      D.increase its popularity

3.The author mentions the example of "backpacks" (Para.2) to show the importance of________.

      A.pleasing the young as well as the old

       B.increasing usage among students

      C.exploring new market sections

      D.finding creative product designers

4.In order to attract more consumers, U.S. auto makers are ________.

       A.modernizing product style

      B.increasing product features

      C.developing products of better quality

      D.re-positioning their product in the market

閱讀下面的短文,并根據短文后面的要求答題。(請注意問題后的字數要求)
     After achieving a 9 percent GDP growth, hosting a successful Olympic Games and carrying out its first
space walk the year before last, you'd think China would be happy. _____. That, at least, is the opinion of a
new book written by a group of Chinese authors.
     China Is Not Happy was published in March,2009.It is a fol low-up to the 1996 work China Can Say No,
a bestseller that complained about the influence of the West and the US in particular, on China. Thirteen years
later, the authors of China Is Not. Happy list their dissatisfaction with how China is being treated in the world
today.
     They argue that China needs to use its growing power and eco nomic resources to build its own position
of preeminence (卓越). "From looking at the history of human civilization, we are most qualified to lead this
world." the book says.
     The authors single out the US for special scorn (輕蔑)."The economic problem has shown the Chinese
people that America does have problems, that what we've been saying is right," said one of the authors.
     The book has become a bestseller in many Chinese bookstores. Yet much of the response to the book has
been negative. Several re- views in the Chinese media have criticized the book's radical (激進的) opinions. The
book is a way to" fish money from the pockets of the angry youth and angry elderly," wrote one critic in the
China Youth Daily. Meanwhile, a well-known sociologist, Li Yinhe, has said that China needs patriotism (愛國
主義),but there is a limit.
      In her blog she wrote,"If we are to bully (欺負) other countries, take the world's resources and try to lead
it, we're going over the top."
1. List three great achievements that China made in 2008 based on the text. ( Please answer within 20 words. )
①_________________________________________________________________________
② ________________________________________________________________________
③ _________________________________________________________________________
2. Fill in the blank in Paragraph 1 with proper words. ( Please an swer within 6 words. )

3. Which sentence in the text is the closest in meaning to the fol lowing one?
     Ancient China was advanced and it was Chinese who created developed civilization, so we
      Chinese should be the leader of the world.
_____________________________________________________________________________
4. What is the main idea of the last Paragraph?( Please answer within 10 words.)
______________________________________________________________________________
5. Translate the underlined sentence in Paragraph 2 into Chinese.
