海淀2007高三数学查漏补缺题

 

07年高考数学北京卷应该是在06年北京卷成功的基础上,稳定的发展,复习中要对各区题目(尤其东城、西城、海淀)文科理科中重点板块不仅要明确知识点,而且还要掌握结构特点,要用联系的思想看知识间的综合,用运动的观点看能力的要求. 高考数学试题是以思维能力考查为主体的,试题展现数学关系常常选取不同展示形式(图表、图象、曲线图、表格、符号、等等)之一,同学们要善于利用数学信息的多种表述分析问题,联系已有知识方法,提高分析问题、解决问题能力.

 

一、函数与导数

1.〖理科〗 已知函数f (x)=6lnx―ax2―8x+b  (a,b为常数),且x =3为f (x)的一个极值点.

    (Ⅰ) 求a;

    (Ⅱ) 求函数f (x)的单调区间;

    (Ⅲ) 若y = f (x)的图象与x轴正半轴有且只有3个交点,求实数b的取值范围.

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

(Ⅱ) 函数f (x)的定义域为(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.

∴函数f (x)的单调递增区间为(0,1)和(3,+∞),单调递减区间为(1,3).

(注:单调区间应分开写,不能用“È”连接)

   (Ⅲ) 由(Ⅱ)可知函数f (x)在(0,1)单调递增,在(1,3)单调递减,在(3,+∞)单调递增.

且当x=1或x=3时,f ′ (x)=0.

∴ f (x)的极大值为f (1)=6ln1+1―8+b=b―7,

f (x)的极小值为f (3)=6ln3+9―24+b=6ln3+b―15.   

∵当x充分接近0时,f (x)<0,当x充分大时,f (x)>0,  

∴要使f (x)的图象与x轴正半轴有且仅有三个不同的交点,只需

 

则7<b<15―6ln3

 

2.〖理科、文科〗设函数,其图象在点处的切线的斜率分别为

(Ⅰ)求证:

(Ⅱ)若函数的递增区间为,求的取值范围;

(Ⅲ)若当时(k是与无关的常数),恒有,试求k的最小值.

(Ⅰ)证明:,由题意及导数的几何意义得

             (1)

,可得,即,故

由(1)得,代入,再由,得

,                         (3)         

代入(2)得,即方程有实根.

故其判别式得      ,或,    (4)           

由(3),(4)得;                       

(Ⅱ)解:由的判别式

知方程有两个不等实根,设为

又由知,为方程()的一个实根,则由根与系数的关系得

,  

时,,当时,

故函数的递增区间为,由题设知

因此,由(Ⅰ)知

的取值范围为;                     

(Ⅲ)解:由,即,即

因为,则,整理得

,可以看作是关于的一次函数,

由题意对于恒成立,

由题意,

,因此的最小值为.  

二、数列

3.对于数列{an}, {cn}数列,其中cn=an+1a(nÎN*).

(Ⅰ) 若数列{an}的通项公式 (nÎN*),求{cn}的通项公式;

(Ⅱ) 若数列{an}的首项是1,且满足cnan=2n

(1) 求证:数列为等差数列;

(2) (理) 若(nÎN*),求证:

 (文) 求数列{an}的前n项和Sn

证明:(Ⅰ)依题意cn=an+1an

∴ cn=

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

            ∴,即.       

              ∵a1=1,,∴是以为首项、为公差的等差数列.

(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〗 设数列的各项都是正数,记Sn为数列的前n项和,且对任意nN+,都有.

   (Ⅰ)求证:=2Snan

   (Ⅱ)求数列的通项公式;

   (Ⅲ)若为非零常数,n∈N+),问是否存在整数,使得对任意 nN+,都有bn+1>bn.

(Ⅰ)证明:在已知式中,当n=1时,

    ∵a1>0   ∴a1=1……………………………………1分

    当n≥2时,  ①

      ②

    ①-②得,…………………………3分

    ∵an>0  ∴=2a1+2a2+…+2an-1+an

    即=2Sn-an  ∵a1=1适合上式

   ∴=2Sn-an(n∈N+)……………………5分

   (Ⅱ)解:由(1)知=2Sn-an(n∈N+) ③

        当n≥2时, =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

∴数列{an}是等差数列,首项为1,公差为1,可得a­n=n………………9分

   (Ⅲ)解:

        欲使

成立 ⑤……………………11分

n=2k-1,k=1,2,3,…时,⑤式即为  ⑥

依题意,⑥式对k=1,2,3…都成立,∴λ<1………………12分

当n=2k,k=1,2,3,…时,⑤式即为  ⑦

依题意,⑦式对k=1,2,3,…都成立,

……………………13分

∴存在整数λ=-1,使得对任意n∈N+,都有>

During a match last year, when he was up 8 to 0, his dad flashed him a   15   ― a quick move of his thumb over the shoulder ― to let Marcus know he   16   allow his opponent (对手) to score   17   once. At 10 to 0, Marcus finally gave   18   a score. He took the next point, for an 11-to-1 victory.

Apart from table tennis, Marcus enjoys Game Boy, basketball and swimming. The straight-A student hopes to study electrical engineering at an Ivy League college when he gets   19  . In the meantime he has two athletic goals: “ 20   in the 2008 Olympics in China and beating my dad on a regular basis.”

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.

     Users have the opportunity to make friends with people who share their interests.

     In the teaching and learning section, there are reading and vocabulary tips for students.

     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.

1. This passage is written to ______.

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 (香气) 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 (得到喜悦) --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 (恶性黑素瘤) by constantly sniffing the skin lesion (损伤). 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 (化疗). 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

                         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 (短吻鳄) 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
