海淀2007高三數學查漏補缺題

 

07年高考數學北京卷應該是在06年北京卷成功的基礎上,穩定的發展,復習中要對各區題目(尤其東城、西城、海淀)文科理科中重點板塊不僅要明確知識點,而且還要掌握結構特點,要用聯系的思想看知識間的綜合,用運動的觀點看能力的要求. 高考數學試題是以思維能力考查為主體的,試題展現數學關系常常選取不同展示形式(圖表、圖象、曲線圖、表格、符號、等等)之一,同學們要善于利用數學信息的多種表述分析問題,聯系已有知識方法,提高分析問題、解決問題能力.

 

一、函數與導數

1.〖理科〗 已知函數f (x)=6lnx―ax2―8x+b  (a,b為常數),且x =3為f (x)的一個極值點.

    (Ⅰ) 求a;

    (Ⅱ) 求函數f (x)的單調區間;

    (Ⅲ) 若y = f (x)的圖象與x軸正半軸有且只有3個交點,求實數b的取值范圍.

解: (Ⅰ) ∵ f ′ (x) =―2ax―8, ∴ f ′ (3) =2―6a―8=0,則a = ―1.  

(Ⅱ) 函數f (x)的定義域為(0,+∞).             

由(Ⅰ) 知f (x) =6lnx+x2―8x+b.

       ∴ f ′ (x) =+2x―8=.  

由f ′ (x)>0可得x>3或x<1,由f ′ (x)<0可得1<x<3.

∴函數f (x)的單調遞增區間為(0,1)和(3,+∞),單調遞減區間為(1,3).

(注:單調區間應分開寫,不能用“È”連接)

   (Ⅲ) 由(Ⅱ)可知函數f (x)在(0,1)單調遞增,在(1,3)單調遞減,在(3,+∞)單調遞增.

且當x=1或x=3時,f ′ (x)=0.

∴ f (x)的極大值為f (1)=6ln1+1―8+b=b―7,

f (x)的極小值為f (3)=6ln3+9―24+b=6ln3+b―15.   

∵當x充分接近0時,f (x)<0,當x充分大時,f (x)>0,  

∴要使f (x)的圖象與x軸正半軸有且僅有三個不同的交點,只需

 

則7<b<15―6ln3

 

2.〖理科、文科〗設函數,其圖象在點處的切線的斜率分別為

(Ⅰ)求證:

(Ⅱ)若函數的遞增區間為,求的取值范圍;

(Ⅲ)若當時(k是與無關的常數),恒有,試求k的最小值.

(Ⅰ)證明:,由題意及導數的幾何意義得

             (1)

代入(2)得,即方程有實根.

故其判別式得      ,或,    (4)           

由(3),(4)得;                       

(Ⅱ)解:由的判別式

知方程有兩個不等實根,設為

又由知,為方程()的一個實根,則由根與系數的關系得

,  

時,,當時,

故函數的遞增區間為,由題設知

因此,由(Ⅰ)知

的取值范圍為;                     

(Ⅲ)解:由,即,即

因為,則,整理得

,可以看作是關于的一次函數,

由題意對于恒成立,

由題意,

,因此的最小值為.  

二、數列

3.對于數列{an}, {cn}數列,其中cn=an+1a(nÎN*).

(Ⅰ) 若數列{an}的通項公式 (nÎN*),求{cn}的通項公式;

(Ⅱ) 若數列{an}的首項是1,且滿足cnan=2n

(1) 求證:數列為等差數列;

(2) (理) 若(nÎN*),求證:

 (文) 求數列{an}的前n項和Sn

證明:(Ⅰ)依題意cn=an+1an

∴ cn=

(Ⅱ)(1)由cnan=2nan+1anan=2n,即an+1=2an+2n.      

            ∴,即.       

              ∵a1=1,,∴是以為首項、為公差的等差數列.

(2)(理)由(1)知an=n?2n-1.             

.       

.                       ∴

=.     

=      

 (文)由(1)得an==n?2n-1,                   

              ∴ Sn = a1+a2+…+an=1?20+2?21+…+n?2n-1,  ①       

              ∴ 2Sn=1?21+2?22+…+n?2n.               ②        

①―②得:― Sn=1+2+22+…+2n-1― n?2n =― n?2n

∴ Sn= n?2n― 2n+1=(n― 1)?2n +1.                            

 

4.〖理科、文科〗 設數列的各項都是正數,記Sn為數列的前n項和,且對任意nN+,都有.

   (Ⅰ)求證:=2Snan

   (Ⅱ)求數列的通項公式;

   (Ⅲ)若為非零常數,n∈N+),問是否存在整數,使得對任意 nN+,都有bn+1>bn.

(Ⅰ)證明:在已知式中,當n=1時,

    ∵a1>0   ∴a1=1……………………………………1分

    當n≥2時,  ①

      ②

    ①-②得,…………………………3分

    ∵an>0  ∴=2a1+2a2+…+2an-1+an

    即=2Sn-an  ∵a1=1適合上式

   ∴=2Sn-an(n∈N+)……………………5分

   (Ⅱ)解:由(1)知=2Sn-an(n∈N+) ③

        當n≥2時, =2Sn-1-an-1  ④

        ③-④得=2(Sn-Sn-1)-an+an-1=2an-an+ an-1= an+ an-1

        ∵an+an-1>0   ∴an-an-1=1……………………8分

∴數列{an}是等差數列,首項為1,公差為1,可得a­n=n………………9分

   (Ⅲ)解:

        欲使

成立 ⑤……………………11分

n=2k-1,k=1,2,3,…時,⑤式即為  ⑥

依題意,⑥式對k=1,2,3…都成立,∴λ<1………………12分

當n=2k,k=1,2,3,…時,⑤式即為  ⑦

依題意,⑦式對k=1,2,3,…都成立,

……………………13分

∴存在整數λ=-1,使得對任意n∈N+,都有>

    Most mornings, Marcus Jackson is up by 6:15. A fourteen-year old in Harry Potter-style glasses, he wastes little   1   before rushing down the stairs of his home.

He’s also   14   a bit of the true spirit of sports.

At 10 to 0, Marcus finally gave   18   a score. He took the next point, for an 11-to-1 victory.

    Learning English is a great challenge, but with a little help from technology it can be as easy as a piece of cake.

         As well as the classroom, teachers and textbooks, the Internet, TV and radio programs can play an active role in helping learn English. The Internet is full of rich and up-to-date information. English learners might wish to try. This website is co-established by the British Council, the BBC World Service and Central Radio and TV University. It provides cultural information about Britain and has an example of the IELTS (International English Language Testing System) that students can use for practice. Different levels of grammar tests can also be found.

    Make friends online

         Another useful website for middle school students and teachers is. Besides reading 21st Century School Edition online, students are also invited to put their views on different topics up on the website.

         Compared with the Internet, TV programs have their own advantages: one does not have to sit at a computer and the audio and visual effects can even be relaxing.

         One popular English-learning program is called "Modern English". This focuses on oral English in practical situations such as taking photos and shopping.

         The short dialogues and useful phrases may help students to express themselves if they go abroad or meet foreigners in China. More than 50 TV stations in about 300 cities have aired the program.

    Word to World

         If you watch Beijing Television Channel 8, you might see a program titled "Study Abroad". On this show Professor Wang Qiang from New Oriental School hosts "From Word to World".

         He selects words with a deep cultural background and teaches useful phrases related to that word. Cartoons are also used to explain how to use the word in daily life. Listening to the radio may not be a new way to learn English but it is easy.

         China Radio International airs a program called "Studio Classroom" at 6:30 a.m. every day. This 25-minute program is aimed at middle school students and covers subjects from current news to travel and history, all in simple language.

    A cactus(仙人掌) stood all alone in the desert, wondering why it was stuck in the middle of nowhere. "I do nothing but stand here all day," it sighed. "What use am I? I’m the ugliest plant in the desert. My spines (脊骨) are thick and prickly (多刺), my leaves are rubbery and tough, I can't offer shade or juicy fruit to any passing traveler. I don’t see that I’m any use at all." All it did was stand in the sun day after day, growing taller and fatter. Its spines grew longer and its leaves tougher... It truly was strange-looking.

    "I wish I could do something useful," it sighed. By day, hawks circled high overhead. "What can I do with my life?" the cactus called. Whether they heard or not, the hawks sailed away. At night, the moon floated into the sky and cast its pale glow on the desert floor. "What good can I do with my life?" the cactus called. The moon only stared coldly as it goes on its way. A lizard crawled by, leaving a little trail in the sand with its tail. "What worthy thing can I do?" the cactus called. "You?" the lizard laughed, pausing a moment. "Worthy deed? Why, you can't do anything! The hawks circle ways overhead, tracing delicate patterns for us all to admire. The moon hangs high like a lantern at night, so we can see our way home. Even I, the lowly lizard can decorate the sands with these beautiful brush-drawings as I pull my tail along. But you do nothing but get uglier every day."

    And so it went on year after year. At last the cactus grew old, and it knew its time was short. "Oh, God" it cried out, "I've wondered so long, and I’ve tried so hard. Forgive me if I’ve failed to find something worthy to do." But just then the cactus felt a strange stirring and unfolding. At its very tip, like a sudden crown, a glorious flower suddenly opened in bloom. Never had the desert known such a blossom? Its fragrance (香氣) perfumed the air far and wide and brought happiness to all passing by.

    The butterflies paused to admire its beauty, and even the moon smiled when it rose to find such a treasure. The cactus heard a voice. "You have waited long," the God said. "the heart that seeks to do good reflects My glory, and will always bring something worthwhile to the world, something in which all can rejoice (得到喜悅) --even if for only a moment."

    1. What does the underlined word "sailed" in the second paragraph mean?

        A. surfed on the water                   B. flew in the sky

        C. moved on a ship                     D. dived into the water.

    2. Whose attitude to the cactus is the worst?

    A. The hawks'.        B. The moon's.   

    C. The lizard's.      D. The butterflies'.

    3. In which paragraph can you find the topic sentence of this passage?

        A. The first.         B. The second.     C. The third.        D. The fourth.

    4. What attitude should lonely ordinary people have in order to build harmonious society?

        A. Aiming high and do admirable things like hawks.

        B. Learning from the cactus to be worried and ashamed of itself.

        C. Acting as the lizard to be proud of itself and look down upon others.

    D. Having a heart that seeks to do good and never gives up.

    In a society where lung and breast cancers are leading causes of cancer death worldwide, early detection of the disease is highly desirable. In a new scientific study, researchers present astonishing new evidence that man's best friend, the dog, may have the ability to contribute to early cancer detection.

    Researchers show scientific evidence that a dog’s extraordinary smelling ability can distinguish people with both early and late stage lung and breast cancers from healthy people. Researchers first discovered this in the case report of a dog warning its owner to the presence of a melanoma (惡性黑素瘤) by constantly sniffing the skin lesion (損傷). Later studies published in major medical magazines proved the ability of trained dogs to detect both melanomas and bladder cancers. The new study is the first to test whether dogs can detect cancers only by sniffing the breath of cancer patients.

    In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer patients. The experiment consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and 83 healthy people. All cancer patients had recently been diagnosed with cancer and had not yet undergone any chemotherapy treatment (化療). The dogs were presented with breath samples from the cancer patients and the healthy ones, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring healthy samples.

    The results of the study showed that dogs can detect breast and lung cancer between 88% and 97%. Moreover, the study also proved that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis may become a potential of cancer diagnosis.

    1. What's the best title of the passage?

       A. Can dogs smell cancer?             

     B. Dogs and treatment

      C. A new research on breast cancer     

     D. An interesting experiment on lung cancer

    2. In this scientific study, five household dogs, ____ lung cancer patients and       healthy people are involved.

        A. 86; 88            B. 31; 97          C. 55; 83           D. 86; 83

    3. The last sentence of the passage means       .

        A. doctors won’t be worried about detecting cancers any more

        B. dogs will be the only way to detect cancers

        C. breath analysis can be used in diagnosing cancers in the future

        D. dogs can use its smell to identify people

    4. The research found that dogs could help detect cancers by_______.

    A. being captured in a special tube     

    B. sniffing the skin lesion

    C. sniffing the breath of the cancer patients

    D. sitting or lying down before a cancer patient

        The Louvre has not always been a museum.  The first building was a castle. In 1190, it was the king's castle with high walls and a round tower. It had a river to keep out the enemies.

        Over the years, the number of the buildings around the castle grew. By 1350, the castle no longer needed to be extended. The Louvre became a palace home for French kings and queens.

        During times of peace, new treasures were brought in. During the days of war, many treasures were stolen, and the buildings were damaged.

        When Francis I became king of France in 1515, he brought in many artists from other countries. One of the artists was Leonardo da Vinci from Italy. Da Vinci's "Mona Lisa" is the best-known painting in the museum today.

        In 1793, the Louvre became a public museum, just as it is now. It is a place where art treasures are kept for everyone to enjoy, Every year millions of people from all over the world come to the Louvre to see the masterpieces.

                             Ecotourism

    The latest buzzword in the tourism industry is “ecotourism”―responsible, environmentally sound vacationing.Ecotourism, or “green tourism,” means taking care of natural resources, protecting endangered species, and preserving and contributing to local communities.

    Armed with this “checklist,” I booked a vacation in an “ecoresort.” The brochure looked appealing---a hotel right on the beach, with a large swimming pool and golf course, in acres of unspoiled rain forest.

    Unfortunately, the only way to get to this resort was a 12-hour flight followed by a long taxi ride.I was relieved to see the hotel at the end of the road.It was a low-rise building, made out of local stone.But as I later found out, in order to build the resort, the wealthy owner had bought up 30,000 square kilometers of unspoiled rain-forest.

    Sunbathing by the glorious swimming pool, enjoying the sound of sprinklers on the golf course, I suddenly realized that this was an area where water is scarce.

    So far, not so eco-friendly.I decided to try some of the trips to nearby conservation projects, to give the resort another chance to convince me.

    Although it was the breeding season for turtles, we didn’t see any.Apparently the large groups of tourists who arrive at the beach to see the turtles laying their eggs have driven the turtles away.A boat ride to a marine park was also disappointing.The noise of the boats means that the alligators (短吻鱷) are afraid to lie in the sun.The tourists, expecting to see some action, throw stones at the alligators in the water, in the hope of getting them to move.

    The trip to the “authentic” local village was pleasant.The resort has turned the local homes into picturesque cottages.However, they are so charming that tourists are buying them, and the locals now live in small towns of badly built houses in the poorest areas of town.

    All in all, my vacation didn’t meet any of the standards for ecotourism.But there are many projects around the world where you can have a genuinely “green ” experience.My next trip is to a mountain village, as a paying guest in a local family’s home.

    I will miss the swimming pool and the golf, though.

    1.What caused the writer to choose this resort?

        A.The advertisement which looked attractive

    B.The resort which was a 12-hour flight away
