The first MP4 player was born years ago. Soon many music fans were wondering how fantastic it is! If you have been into technology enough, perhaps you may have a knowledge of the MP4. If not, you do need to know something before buying one, even if you are familiar with MP3. MP3 is the CD-like disc with greater capacity. How about MP4? This small digital product will really enrich the joy from listening to music. You can even feel the “touch” of music to your soul!
Now, some similar digital products advertised as “MP4 players” are simply MP3 players, which do not play video and MPEG format (格式) and also lack other particular functions. These products confuse some buyers, as they may think the “MP4” players simply mean they can do more than MP3.
What is MP4?!
It is a multimedia container. It is not only used to store digital audio (音頻) and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles (字幕) and pictures. As a most modern container format, it allows streaming over the Internet.
With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality. By installing (安裝) DVD-MP4 software, you can transfer particular music from a DVD to an MP4 video file. It really excites your listening music experience. 
Then, there is MP4 advanced and you can set your own collection of all the programs — TV shows, games, and music. You can even see movies which are still running in cinemas. What else digital product could you possibly ask for? 
57. It is suggested here that you should ________ before buying an MP4 player
A. first be a music fan                                 B. have a knowledge of MP4
C. get familiar with MP3                                  D. buy a CD-like disc
58. From the passage, we can see that MP4 is ________ MP3. 
A. much bigger than              B. just as advanced as  
C. not so particular as              D. more functional than
59. Which function of MP4 is NOT directly mentioned in this passage?
A. Storing digital audio and video streams.    B. Recording some movies in cinemas.
C. Playing TV shows, games and movies.      D. Transferring particular music from a DVD.
60. From the last sentence, it’s clear that the writer tries to tell us it is _______.
A. reasonable to buy other digital products    B. impossible to buy something else
C. a very wise choice to buy an MP4       D. an exciting experience to buy an MP3

Labor force is defined as being the total number of people who are available to work and earn income.This definition includes everyone who is employed or seeking paid employment,so it includes employers and the self-employed.Labor is one of the country's resources which can be combined with other resources to produce the goods and services wanted by the community.
Although the size of the workforce depends a great deal on the size of the total population,there are several other influences which also affect it.The age distribution (分布) of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work,then the available workforce would be lower than if there were an balanced spread age distribution.If the population naturally grows rapidly, the number of births greatly exceeds (超出) the number of deaths then as a total population increases proportion of the workforce declines.
Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly,and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it.In that situation the population is top-heavy with older people.So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.
The age distribution of the population has several important effects on the economy.If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce,this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group.If the aged are to be cared for in special homes,finance must be available for that purpose.If the size of the workforce is small relative to the total population,then the government tax revenue(稅收) is relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.
72.In the passage “l(fā)abor force” is defined as ___________.
A.people who are available to work and earn income
B.self-employed people only
C.people who are looking for an employment
D.employers who create job opportunities
73.The conclusion which can be drawn from the second paragraph is that___________.
A.a(chǎn) natural growth of population leads to a balanced workforce
B.a(chǎn) large population does not necessarily mean a higher proportion of workforce
C.the larger the population,the higher the proportion of the workforce
D.the workforce will be lower, if the population has a balanced age distribution,
74.When a population is said to be aging,___________.
A.there are more people retiring than those entering the workforce
B.the birth rate must be growing
C.there should be an oversupply of workforce
D.There are more people entering the workforce than those retiring
75.The population which is top-heavy with older people ___________ of a country.
A.leads to the high rate of unemployment 
B.results in low tax on the workforce members 
C.a(chǎn)ffects employees’ incomes
D.places pressure on the economy

Dear Betty,
My roommate’s family wants me to celebrate Thanksgiving Day with them in their home. I accepted the invitation, and I’m excited about going, but I’m a little nervous about it, too. The social customs in my country are different from those here, so I’m a little worried about making mistakes.
Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late?  At the dinner table, how can I know which fork or knife to use? How can I let the family know that I’m thankful for their kindness?
Yours,
Knowing Nothing
Dear Knowing Nothing,
It’s a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it.
You should arrive on time or five to ten minutes late. Don’t get there early. If you are going to be more than fifteen minutes late, you should call and tell them.
Try to relax at the dinner table. If you don’t know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don’t be shy about asking the person next to you; it’s better to ask them than to be silently uncomfortable and nervous.
If you like the food, say so. Of course, you’ll thank the host and hostess for the meal and for their kindness. It’s also a good idea to send a card to thank them the day after.
Yours,
Betty
56. Knowing Nothing wrote a letter to Betty to _____.

I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard keeping my house from becoming a battlefield.
It got worse as they grew older. Three years ago, Zack, then 16, couldn’t make it through a day without making his sisters, Alex 11 and Taryn 9, angry.
My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was “I say it because it’s true.”
I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister, Mary, in an e-mail. She replied, “Don’t e-mail me. E-mail him.”
Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn’t say anything different, but e-mail just took the tension away. There’d be no shouting or door banging. Zack wouldn’t feel under attack.
Zack didn’t reply for days. When he finally did, his entire message was four small words. I smiled when I read them: “You’re right. I’m sorry.”
The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don’t tune me out as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, “You’re so much nicer online.”
All I know is that the house is quiet. But we’re talking.
71. What was the trouble before the online talk in the family?
A. The writer failed to understand her daughters.
B. The children couldn’t get along peacefully.
C. The family found it difficult to keep the house clean.
D. The parents were not willing to talk with their children.
72. The writer once tried to deal with her son’s problem by _______.
A. talking with him about his pain
B. telling him about the truth of the family
C. telling her daughters to keep away from him
D. encouraging her daughters to fight against him
73. The writer e-mailed her sister _______.
A. to tell her about the family problem        B. hoping she’d e-mail the boy
C. asking about child-raising                      D. to escape from the problem
74. The underlined phrase “tune me out” in the passage probably means _______.
A. quarrel with me                                    B. get angry with me
C. pay no attention to me                           D. keep me out of their rooms

Besides relevant theories and keen logic, a scientist who does research in economic psychology and who wants to predict the way in which consumers will spend their money must study consumer behavior.  It’s vital for his credit as a qualified economist.   He must obtain numbers and material both on the resources of consumers and on the efforts that tend to encourage or discourage money spending.
If an economist were asked which of the three groups borrow most——people with rising incomes, stable incomes or declining incomes——he would probably answer: those with declining incomes.  Actually, in the past 5 years, the answer was: people with rising incomes.  This shows us that traditional assumptions about earning and spending are not always reliable.  Another traditional assumption is that if people who have money expect prices to go up, they will hurry to buy.  If they expect prices to go down, they will postpone buying.  But research surveys have shown that this is also not always the case.  Their expectations of price increases may not stimulate buying.  One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices.  “In a few months,” she said, “we’ll have to pay more for meat and milk.  We’ll have less to spend on other things.”  Her family had been planning to buy a new car but they postponed this purchase.  Furthermore, the rise in prices that has already taken place may be hated and buyer’s resistance may be caused.  This is shown by the following typical comment of the wife: “I just don’t pay these prices: they are too high.”
Traditional assumptions should be investigated carefully, and factors of time and place should be considered.  The investigations mentioned above were carried out in America.  Research conducted at the same time in Great Britain, however, produced results that were more in agreement with traditional assumptions about saving and spending patterns.  The condition most beneficial to spending appears to be price stability.  If prices have been stable and people have become accustomed to considering the current prices “right”, they are likely to buy.  Thus, in a society of good economy which maintains consumer confidence, it appears that the common business policy of maintaining stable prices with occasional sales or discounts is based on a correct understanding of consumer psychology.
72. According to the passage, it is essential for a successful economist to ______.
A. know about economic theories 
B. be capable of logical thinking
C. predict the latest national economy
D. to understand consumers’ spending habits
73. The example of the mechanic’s wife is intended to show that ______.
people tend to buy more when prices are expected to fall
people tend to buy less when prices are expected to fall
people tend to buy more when prices are expected to rise
people tend to buy less when prices are expected to rise
74. Findings in investigations in Britain show _____.
consumer behaviour may vary in different places
Britain and America share similar saving and spending patterns
Britain is important in economic research
occasional discounts and sales are important
75. According to the passage, what is most helpful in promoting spending?
A. Big discount.     .      B. Good consumer confidence.
C. Steady price.            D. Positive consumer psychology.

I strongly believe it’s happy to have a day in the year , when we can toghter talk about the progress women have made over the years , although we still have to deal with many more lifestyle pressures compared to men.
For all the fellow sisters who’ve still not figured out the power of being a woman,it’s high time to realize how easy it is for us to brust into tears in public to get the pressure out ,or cry for emotional reasons, or for no specific reason at all.       Our tears are at least regared as an outlet for emotional stress ,and not as a sign of weakness . Please allow me to say jokingly here——the tears can best be used as a winning tool in an argumentative——your point will have to be heard and agreed upon!
We are socially  acoepted as proud “homemakers”if we choose to live that way . What a relief from the social burden of “earning enough for the family “.
We have the amazing option of wearing make-up. Of course , we are “natural beauties “, but who minds improving those pretty looks ! How easy it is for us to look taller whenever we want to. We can wander in those fashionable dresses and don’t lack choices when it comes to dressing up for parties and weddings .
What an advantage : You can wear his shirts or T-shirts if you want, but poor he can’t even think of feel getting into any of your designer dresses !
You can’t ignore the benefits that may come in your way from men in the name of gentleman’s behavior ! You can feel important every time he opens the car door for you before sitting into the driver/s seat hinself.
If you’re a daddy’s girl , you can comfortably feel most protective . But as to a mamma’s boy , he isn’t easy .
Cheers to the “advantages of womanhood”.

A , the difference between being a woman and being a man
