Ⅲ.阅读理解
Scientists now know a lot more about a grain that people have eaten for ten thousand years.Research teams around the world have completed a map of the genes of rice.Such a map is called a genome(基因组)．The findings appeared last week in the magazine Nature.
The map represents ninety-five percent of the rice genome.And the information is considered ninety-nine point nine-nine percent correct.The aim is to speed up the improvement of rice.The scientists warn that the kinds of rice plants used now have reached the limit of their productivity.Yet world rice production must grow by an estimated thirty percent in the next twenty years to meet demand.In their paper, the researchers say rice is an excellent choice for genetic and and engineering.Rice genes have only about three hundred and ninety million chemical bases.That might sound like a lot.But other major food grains have thousands of millions.
The new map could better explain not just rice.Rice shares a common ancestor with other crops in the grass family.These include corn and wheat.Also，rice shares more than seventy percent of its genes with Arabidopsis.This plant is in the mustard family.Its genome was completed in two thousand.Genes produce proteins which guide the building of organisms.Genes are placed along chromosomes(染色体)．Rice has twelve chromosomes.The scientists found almost thirty-eight thousand genes.By comparison，studies have found only about twenty-five thousand genes in humans.
The International Rice Genome Sequencing Project in Tsukuba，Japan，led the research.The effort started in 1998.The Rice Genome Research Program in Japan supervised (监督) the mapping of about half of the genome.American researchers were responsible for three chromosomes.Chinese and Taiwanese researchers mapped one each.A French group mapped one and part of another.Researchers in Brazil, Britain, France, India, South Korea and Thailand also took part.
The project was expected to take ten years.But the work was finished in six because many of the groups shared information and technology.Two companies, Monsanto of the United States and Syngenta of Switzerland, also shared their research.
1．The researchers chose rice as their experimental object because________.
A．rice is the main food grain for people on earth
B．rice has a smaller chemical bases than other plants
C．it is easier to map the genes of rice than other plants
D．rice production must grow a lot in the next 20 years
答案 B [由第二段后半部分知答案为B项。]
2．From the passage we can infer________.
A．corn has a different ancestor with rice
B．the map made by the researchers can explain rice but not others
C．proteins produced by genes guide the building of organism
D．there will be a big increase in population in the latest 20 years in the world
答案 D [由第三段知A、B表述错误。C项表述正确但并非推断出的。由文章第二段的“Yet world rice production...to meet demand.”可推知人口将会有较大的增长。故选D项。]
3．How many countries joined in the research?
A．9. B．10. C．11. D．12.
答案 B [共有这些国家参与了研究：Japan，America，China，France，Brazil，England，India，South Korea，Thailand，Switzerland。]
4．From the last paragraph we know________.
A．the research will be finished in 10 years
B．six years is enough for the research teams
C．the quick success of the research is based on the co-oper-ation of researchers from different countries
D．an organization of Japan led the research
答案 C [由“...because many of the groups shared information and technology.”知选C项。]

2．We had to wait months for the government to ________our plans to carry out the project.
A．evaluate B．consult
C．approve D．adopt

3．No matter what I do, my mother is always ________， which made me successful.
A．in my favour B．in my hand
C．in my heart D．in my mind
答案 A [in one's favour支持某人。]
4．They pass their knowledge________from one generation to the next in stories and rhymes.
A．on B．out C．around D．down

5．—Wow！You've got so many clothes.
—But ________of them are in fashion now.
A．all B．both
C．neither D．none
答案 D [句意：——哇！你有这么多衣服啊。——但是现在没有一件是时尚的了。根据句意，空格处应用否定词，应排除A、B两项；衣服多，应该是大于三者，用none。注意neither和none的用法不同。前者表示“两者都不”，后者表示“三者或三者以上都不”。]
6．The more I think about him，the more reasons I find for loving him________I did.
A．as much as B．as long as
C．as soon as D．as far as

A. who B. whom C. which D. /
答案 A [本题考查由who引导的定语从句，由先行词no one决定了引导词用who或whom，而定语从句中又缺主语，决定了该选A项。]
8．I would appreciate________， to be frank, if goods could be delivered as soon as possible.
A．you B．this C．it D．myself
答案 C [句意：说实话，如果货物能尽快被送走，我会不胜感激。it常用在不能直接跟宾语从句的动词，尤其是表示好恶的动词之后，如：enjoy, love, dislike, be fond of, appreciate等，也就是说这些动词后的宾语从句前要加it。如：I like it when she sings a song for me.]
Ⅱ.阅读理解
Elena Kagan has reached a lifelong goal：becoming a Justice on the United States Supreme Court.The U．S.Senate confirmed Kagan on Thursday by a vote of 63－37.She replaces Justice John Paul Stevens, who retired in June.
Kagan will take a sacred oath (誓言) to uphold the Constitution of the United States on Saturday at a swearing-in ceremony.The new Justice will bring the number of women sitting on the nation's highest court to three.Kagan joins Justices Ruth Bader Ginsburg and Sonia Sotomayor—all three New Yorkers.
Kagan is the fourth woman in history to sit on the Supreme Court.Justice Sandra Day O'Connor was the first female Justice.She was appointed by President Ronald Reagan and served from 1981 to 2006.
Kagan, who is 50 years old, is the second Justice appointed by President Barack Obama.(He appointed Justice Sotomayor in 2009.)Obama told reporters on Thursday that Kagan will make an “outstanding Justice who understands that her rulings affect people.”He also noted that the addition of another woman to the Supreme Court marks a sign of progress for the country.Obama and Kagan will celebrate her confirmation with a ceremony at the White House today.
Kagan has spent most of her adult life working with the law.She served in President Clinton's administration as a legal adviser, was the head of Harvard Law School, and until her confirmation Thursday, was the U．S.Solicitor General—one of the most powerful lawyers in the federal government.Kagan was born in New York City.She grew up in an apartment on the Upper West Side of Manhattan, the strong-willed, independent middle sister sandwiched between two brothers.
Kagan's mother was a public school teacher who taught fifth and sixth grades.Her father was a lawyer.
The new Justice once wore a judge's robe in a picture for her high-school yearbook.Now she'll be wearing real ones as she and the other eight Justices decide some of the most important legal cases.

C．Kagan achieved this position in the election by beating John Paul Stevens.
D．It will take a long time for Kagan to become a Justice on the United States Supreme Court.

B．There will be four women working in the United States Supreme Court.
C．Kagan will take a sacred oath before taking part in the election.
D．No one but a New Yorker can be a Justice of the Supreme Court.
答案 A [根据第一段最后一句，由于前法官退休，美国参议院不得不选举一个新法官顶替他的位置，才会有艾琳娜·卡根当选。]
3．What can we infer from Obama's words?
A．He will appoint more women Justices to the Supreme Court.
B．He appointed Kagan as she had done a good job before.
C．There is much to be improved on the Supreme Court.
D．He is sure Kagan will be excellent in her new work.
答案 D [根据Obama told reporters on Thursday that Kagan will make an “outstanding Justice who understands that her rulings affect people.”可知，奥巴马相信卡根会用她出色的工作影响人们，成为一位杰出的法官。]
4．What is the main idea of paragraph 5?
A．Kagan is a born lawyer.
B．It is about Kagan's biography.
C．Kagan's character is fit for her job.
D．Kagan has worked for two Presidents.

I am a doctor working in a community and many of my clients' families live in bad condition.
This year，an old lady that I cared for，Alice，went through a particularly rough time.She had been in hospital twice and was then sent to a nursing home.__1__
Alice had dementia(痴呆)and thought her daughter was coming to visit on Christmas Day and that they were going to have the whole family together like the old days.When she finally realized that was not going to happen she was so sad and tearful.Knowing that her daughter was coming after Christmas was not enough to cheer her up.__2__
On Christmas Eve，I surprised her by asking if she would like to go to a candlelit service at church that night.
Instead of taking her to my church，I took her to her old neighborhood church where all her friends were.
__3__God and his angels had a hand in the plan and it worked out perfectly.All of her friends seemed to be there and rushed over to greet her and sit with her.

4．What you said was true.It was, ________， a little unkind.
A．moreover B．therefore
C．but D．nonetheless

5．Mr.Wang________his dog against accident.
A．insured B．ensured

Jenny was almost five.Waiting with her mother at the checkout stand, she saw a circle of white pearls in a box.“Oh, can I have them？Mommy, please！”
Quickly the mother checked the back of the little box and said，“That's almost $2.00.If you really like them, I'll think of some extra chores for you and soon you can save enough money to buy for yourself.”
Then Jenny began doing more chores at home and did housework for neighbors.On her birthday, Grandma gave her another dollar bill and she had enough money to buy the necklace.
Jenny loved her pearls.She wore them everywhere, even to bed.
Jenny had a loving daddy and every night when she was ready for bed, he would stop whatever he was doing to read her a story.One night, he asked Jenny，“Do you love me？”
“On, yes, Daddy.You know that I love you.”
“Then give me your pearls.”
“Oh, Daddy, not my pearls.But you can have my Princess.”
“That's okay, Honey.Daddy loves you. Good night.”And he brushed her cheek with a kiss.
About a week later, after the story time, Jenny's daddy asked for the pearls again.And Jenny refused him again.
A few nights later when her daddy came in, Jenny was sitting on her bed with her legs crossed.As he came close, he noticed one silent tear rolling down her cheek.
“What is it, Jenny？What's the matter？”
Jenny lifted her little hand up to her daddy.And when she opened it, there was her little pearl necklace.She finally said, “Here, Daddy.It's for you.”
With tears gathering in his own eyes, Jenny's kind daddy reached out with one hand to take the dime store necklace, and with the other hand he reached into his pocket and pulled out a blue case with genuine pearls and gave them to Jenny. He had had them all the time. He was just waiting for her to give up the dime store stuff so he could give her the genuine treasure.
