三．16. （1） a6a2 （2）aa1aa9
17．解:设u=
x1
x1
,任取x2＞x1＞1,则 ux1x11(x21)(x2－u1=211)(x11)(x21)2(x1x2)x
x==. 2111(x21)(x11)(x21)(x11)
∵x1＞1,x2＞1,∴x1－1＞0,x2－1＞0. 又∵x1＜x2,∴x1－x2＜0. ∴
2(x1x2)
(x＜0,即u2＜u1.
21)(x11)
当a＞1时,y=logax是增函数,∴logau2＜logau1,即f(x2)＜f(x1); 当0＜a＜1时,y=logax是减函数,∴logau2＞logau1,即f(x2)＞f(x1).
综上可知,当a＞1时,f(x)=logx1
ax1在(1,+∞)上为减函数;
当0＜a＜1时,f(x)=logx1
ax1
在(1,+∞)上为增函数.
18、（1）设月产量为x台,则总成本为20000+ 100x,从而利润
f(x)12x2
300x20000,0x400,
60000100x,x400.
（2）当0x400时，f(x)= 12
(x300)2
25000,所以当x=300时，有最大值25000；当x>400时，f(x)=60000-100x是减函数， 所以f(x)= 60000-100×400<25000。 所以当x=300时，有最大值25000，
即当月产量为300台时，公司所获利润最大，最大利润是25000元。
19、解：(1)因f(x)是R上的奇函数。所以f(x)+f(x)=0 所以过原点。a=1.
(2)定义域为R 设x1,x2R且x1x2则：
f(x22222)f(x1)=a2x2
12121212(2x22xa1)
x1x2x1(2x11)(2x2
1)
. y2x为增函数,且x2x1,2x22x1而分母大于0恒成立
f(x2)f(x1)>0f(x2)f(x1) 故f(x)是R上的增函数
(3)由f(x)0恒成立,可得a
2
2x1
恒成立 0

2要使其恒成立,只需a2 a的取值范围是[2,) 20、解（1）令y=0，x=1 则
f(1)f(0)20 f(0)2
（2）令y=0 即f(x)f(0)(x1)xx2x2
（3）
f(x)32xa 即x2x232xa
ax2x1在x10,
上恒成立

设g(x)x2
x1(x12)234 ， x0,1
2
即ag(x)1max 又g(x)在0,
2上递减
ag(0)1 故a的取值范围是(1,)
21. 解：（1）由等式的log
1yyxlog1
xx3

yx3，则y1x
x3即yx1
x0由题意知y0且y1,解得x1，f(x)xx3的定义域是1,x1

易得函数fx的值域是9,

（2）若存在满足题意的实数m，则关于x的方程mfx
fx10
在区间1,上有实解 令
fxu ，则由（1）知u3,
问题转化为关于u的方程mu2
u10在区间3,上有实解，

A
Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea．People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea．Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added．She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.
At first, tea was usually drunk after dinner in the evening No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o’clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born.
56．Which of the following is true of the introduction of tea into Britain?
A. The Britons got expensive tea from India. B. Tea reached Britain from Holland.
C．The Britons were the first people in Europe who drank tea. D．It was not until the 17th century that the Britons had tea. 57．This passage mainly discusses_____________.
A．the history of tea drinking in Britain B．how tea became a popular drink in Britain
C．how the Britons got the habit of drinking tea D．how tea-time was born
58．Tea became a popular drink in Britain.
A．in eighteenth century B．in sixteenth century
C．in seventeenth century
D．in the late seventeenth century 59．People in Europe began to drink tea with milk because.
A．it tasted like milk
B．it tasted more pleasant C．it became a popular drink
D．Madame de Sevinge was such a lady with great social influence that people tried to copy the way she drank tea
60．We may infer from the passage that the habit of drinking tea in Britain was mostly due to the
influence of ________. A．a famous French lady B．the ancient Chinese C．the upper social class
D．people in Holland
B
It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies,
they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor decided that single men could become better soldiers than those with wives, he didn’t allow marriage.
But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.
Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends.
