Ⅱ、(本小題共10分)由于在“基因靶向敲除”技術(shù)方面獲得重大成果,兩位美國科學(xué)家和一位英國科學(xué)家分享了2007年諾貝爾生理或醫(yī)學(xué)獎(jiǎng)。“基因靶向敲除”是指利用細(xì)胞內(nèi)的DNA可與外源性DNA同源序列發(fā)生同源重組的性質(zhì),用設(shè)計(jì)好的DNA片段替代動(dòng)物細(xì)胞內(nèi)的基因片段,從而達(dá)到基因敲除目的,其基本原理如下圖所示。

 

 

 

 

 

 

請(qǐng)回答下列問題:

(1)關(guān)于“基因靶向敲除”技術(shù),下列說法不正確的是(    )

    A.“基因靶向敲除”其實(shí)質(zhì)就是人為的基因重組技術(shù)

    B.“基因靶向敲除”的濫用,會(huì)導(dǎo)致基因污染的生態(tài)災(zāi)難

C.“基因靶向敲除”成功導(dǎo)入的目的基因,其遺傳仍可能遵循孟德爾遺傳定律

    D.“基因靶向敲除”成功的關(guān)健是目的基因能否成功導(dǎo)入受體細(xì)胞

(2)從獲取目的基因到將目的基因?qū)胧荏w細(xì)胞前,兩次使用了同一種基因操作工具,該工具是                。

(3)要想獲得一只含目的基因的小鼠,一般是通過病毒感染或顯微注射技術(shù)將目的基因?qū)胧芫?/p>

選擇受精卵作受體細(xì)胞的原因是,從細(xì)胞分化角度講                。

(4)在此類基因操作中,通常可以用水母的發(fā)光蛋白作為標(biāo)記物。水母發(fā)光蛋白有發(fā)光環(huán),能在一定

條件下發(fā)出熒光,現(xiàn)已將這種蛋白質(zhì)的基因作為生物轉(zhuǎn)基因的標(biāo)記,在轉(zhuǎn)基因技術(shù)中,這種蛋白質(zhì)的作用是(     )

    A.便于獲取目的基因                B.便于目的基因在宿主細(xì)胞中擴(kuò)增

    C.便于目的基因的轉(zhuǎn)移容易被檢測    D.便于目的基因的表達(dá)

(5)按上述“基因靶向敲除”操作獲得的小鼠其基因是雜合的,為更好地研究該動(dòng)物細(xì)胞內(nèi)靶基因的功能,人們想獲得一個(gè)含純合目的基因的個(gè)體,下一步該如何實(shí)驗(yàn)操作?

31.(本小題共14分,每空2分)科學(xué)家通過研究分析得知植物成熟葉中含有較多的脫落酸而不含細(xì)胞分裂素。進(jìn)一步研究分析得知:脫落酸有抑制核酸、蛋白質(zhì)的合成并提高核酸酶活性,從而促進(jìn)核酸的降解,使葉片衰老;而細(xì)胞分裂素則抑制葉綠素、核酸和蛋白質(zhì)的降解,抑制葉片衰老。所以在生產(chǎn)中可利用細(xì)胞分裂素作保鮮劑。請(qǐng)你設(shè)計(jì)一個(gè)實(shí)驗(yàn)證明細(xì)胞分裂素有延緩葉片衰老的作用。

(1)實(shí)驗(yàn)原理:葉綠素逐漸喪失是葉片衰老最明顯的特點(diǎn),離體葉片很快就會(huì)出現(xiàn)衰老的特點(diǎn),因此本實(shí)驗(yàn)可通過                                作為指標(biāo)來檢測細(xì)胞分裂素的作用。

(2)實(shí)驗(yàn)步驟:

    第一步:選取                                  葉片若干,均分成兩組,分別標(biāo)記為甲、乙。

    第二步:在甲組葉片的局部位置涂上一定濃度的細(xì)胞分裂素,乙組葉片                      

第三步:記錄兩組葉片失綠變黃的時(shí)間。請(qǐng)?jiān)O(shè)計(jì)一表格,以便科學(xué)地記錄數(shù)據(jù)。

 

 

 

 

 

(3)實(shí)驗(yàn)結(jié)果預(yù)測及結(jié)論:

      第三部分:閱讀理解(共20小題;每小題2分,滿分40分)

      第一節(jié):選擇題(共17小題:每小題2分,滿分34分))

      閱讀下列短文,從每題所給的A、B、C和D四個(gè)選項(xiàng)中,選出最佳選項(xiàng)。

      A

      It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling(擁擠)together inside the storm door on the top step.

      “Any old papers, lady?” asked one of them.

      I was busy. I wanted to say “no” until I looked down at their feet. They were wearing thin?little sandals(便鞋), wet with heavy snow.

      “Come in and I’ll make you a cup of hot cocoa.”

      They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget.

      The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich?”

      I looked at my shabby slipcovers(沙發(fā)套). The girl put her cup back in its saucer(茶碟)carefully and said, “Your cups match your saucers.” Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn’t said “Thank you.” They didn’t need to. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched.

      I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job ? these matched, too.

      I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am.

      56. Two children came to the writer’s front door because        .

          A. it was Thanksgiving Day.                               B. they were beggars

          C. they wanted old papers                                   D. they wanted a cup of cocoa

      57. Why did the writer let the children in?

          A. She showed great pity on them.                      B. She had old papers to sell.

          C. She wanted to invite them to dinner.                D. She wanted them to see how rich she was.

      58. From the passage, we can infer that whether you are rich depends on        .

          A. how much money you have had                     B. how you feel about your life

          C. how you have helped others                            D. what job your husband is doing

      59. The writer left the muddy prints of small sandals on the floor for a while to      .

          A. show her husband that someone had come        B. remind her that she had helped two children

      C. remind her that she was very once rich            D. remind her how life should be

       

      B

      Small discoveries in Indonesia are causing a stir in the science world. Researchers have unearthed (挖掘) tiny bones that they believe belong to an entirely new human species. If that’s true, it will change how we think about our ancestors.

      Clues that the little people may have lived long ago were first revealed last year in the scientific journal Nature. Scientists said that they had found the bones of a three-foot-tall female on the island of Flores, in Indonesia. When they looked more closely, they saw that the nearly complete skeleton (骨骼) belonged to a full-grown adult. Researchers named her Hobbit, after the tiny heroes of the Lord of the Rings books.

      Now the team is saying it has unearthed even more pieces of the puzzle, including a jawbone and parts of arms, legs and hands from several individuals, as well as stone tools. They reported their find in Nature this month. “The new evidence makes it very clear that these people are a new species, distinct from modern humans,” Peter Brown, a scientist on the team, said. They named these ancient humans Homo floresiensis.

      Brown says that these little people lived as recently as 12,000 years ago. If Homo floresiensis was a different species from modern humans, that would make our family tree bigger than we knew. It means, says Brown, that “until recently, a relative shared the planet with us.”

      Many scientists think a new species is unlikely. Some argue that the bones must have belonged to modern humans whose small size was the result of a genetic problem.

      Daniel E. Lieberman, a scientist at Harvard University, thinks that the debate over the discovery is healthy. He believes that the questions and arguments raised by critics will help us learn more about these unusual skeletons. “Disagreement is an important part of the scientific process,” Lieberman said. “As far as I’m concerned, the story’s only just begun.”

      60. Researchers name the skeleton Hobbit because _____.

      A. it is a figure described in the Lord of the Rings   B. it resembles the tiny heroes in a set of books  

      C. it proves to be a full-grown adult                      D. it belongs to an ancient human species

      61. Small discoveries in Indonesia are important because they _____.

      A. are revealed in the scientific journal Nature        B. are made by Peter Brown, a famous scientist

      C. are about ancestors of modern humans              D. might provide new evidence for human study

      62. According to Daniel E. Lieberman, _____.

        A. Homo floresiensis doesn’t exist                   B. disagreement leads to further research

        C. the investigation hasn’t begun yet                 D. our family tree is bigger than we knew

      63. Which of the following might be the best title of the passage?

      A. Comparison between Different Peoples             B. Arguments over Human Origin

      C. Discovery of a Possible New Human Species    D. History of Indonesian People

                                            C

      Every year, the American Library Association honors artists and writers of books for children. One of these honors is the Newbery Award. It is named after a book seller in England in the 18th century, John Newbery.

      The Newbery Medal winner for 2006 is Lynne Rae Perkins for writing Criss Cross. Her book is about four teenagers in a small town. They are trying to find the meaning of life and love. They are fourteen years old. Criss Cross is written in several different ways. Sometimes it is like a song. Sometimes it is like a poem. Lynne Rae Perkins is a writer and artist. Criss Cross is her sixth book.

             Another award, the Caldecott, honors the best American picture book of the year. It is named after an artist from England, Randolph Caldecott. The Caldecott Medal winner this year is Chris Raschka for the book The Hello, Goodbye Window, written by Norton Juster.

             In the book, a little girl tells about visiting the home of her grandparents. The committee that chose Chris Raschka for the award praised how he captures the natural way children draw. It says the pictures express the emotional warmth of connections between older family members and children, Chris Raschka also won the award in 1994. In addition to the winners, four Caldecott Honor Books and four Newbery Honor Books were named last month.

      Another honor from the American Library Association is the Margaret L. Batchelder Award. It goes to the company that publishes the best translation of a children’s book into English. The winner for 2006 is Arthur A. Levine Books for the book An Innocent Soldier written by Josef Holub. Michael Hoffman translated it from German.

             Awards are chosen by committees of people who work with children’s books. But in some schools, children vote unofficially for their own Newbery and Caldecott winners. This year, schoolchildren could watch the award ceremony live on the Internet. A teacher in Wisconsin says her students cheered as each winner was announced.

      68. The passage is probably about ______.

      第二節(jié) 簡答題(共3小題, 滿分6分)

      閱讀下面短文,根據(jù)第73至第75小題的具體要求,簡要回答問題。

      Ballroom dancing

      Ballroom dancing(交際舞)in the UK used to be seen as something rather unpopular that old people might do. For the past five years though, the popularity of ballroom dancing has soared(高漲)thanks to a reality TV show. Every Saturday night millions of people watch the show which airs from September right up to Christmas. In the show a number of professional ballroom dancers each partner a celebrity(名流). Every week they have to learn a different ballroom dance and perform it live on TV on the Saturday night.

      Four judges, all of whom have a background in professional dance, give the celebrities scores and comments about their dances. It is then up to the public to call in and vote for their favorite couple. The two least favorite then have to dance again and the judges decide who stays in the competition and who leaves. The celebrities get to wear colorful dresses to dance in, and it looks like a lot of fun.

      The TV program also shows what good exercise it can be to ballroom dance and what hard work is involved(涉及)in learning the dances and performing them properly. Dance schools around the country have seen an increase in the number of people wanting to learn how to dance. And it’s not only older people who are interested. Lots of children and young people in their 20s are eager to learn.

      The show demonstrates how glamorous(富有魅力的)ballroom dancing is. The format(形式)for the show has been copied in lots of countries around the world. In America, the show is called Dancing with the Stars and at the moment they are doing very well in the show. In the British show there are famous TV stars and former sportsmen taking part. So you can forget your usual exercise?why not learn a foxtrot(狐步舞), a tango or the less energetic waltz. It’s the fashionable thing to do!

      73. Find in the passage a word closest in meaning to the underlined word “demonstrates”.

       

      74. Why are so many people interested in ballroom dancing in the UK? (回答詞數(shù)不超過8個(gè))

       

      75. How does the TV show make so many people enjoy the TV program?(回答詞數(shù)不超過8個(gè))

      The US Department of Labor statistics show that there is an oversupply of college trained workers and that this oversupply is increasing. Already there have been more than enough teachers, engineers, physicists, aerospace experts and other specialists. Yet colleges and graduate schools continue every year to turn out highly-trained people to compete for jobs that aren’t there. The result is that graduates cannot enter the professions for which they were trained and must take temporary jobs which don’t require a college degree.

         On the other hand, there is a great need for skilled workers of all sorts. These people have more work than they can deal with, and their annual incomes are often higher than those of college graduates. The old gap that white-collar workers make a better living than blue-collar workers no longer holds true. The law of supply and demand now favors the skilled workmen.

      The reason for this situation is the traditional myth that college degree is a passport to a prosperous future. A large part of American society matches success in life equally with a college degree. Parents begin indoctrinating(灌輸) their children with this myth before they are out of grade school. High school teachers play their part by acting as if high school education were a preparation for college rather than for life. Under this pressure the kids fall in line. Whether they want to go to college or not doesn’t matter. Everybody should go to college, so of course they must go. And every year college enrollments go up and up, more and more graduates are overeducated for the kind of jobs available to them.

      The development of our society is made by all kinds of workers. Only when the need of them is balanced can our nation process healthily. So parents and teachers are wished to pay more attention to the children’s choices.
