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 player” are simply MP3 players, which do not play video and MPEG format 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 and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles 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 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 cinema. What else digital product could you possibly ask for?
小題1:. It is suggested here that you should ______ before buying an MP4 player.
A.first be a music fanB.have a knowledge of MP4
C.get familiar with MP3D.buy a CD-like disc
小題2:. From the passage, we can see that MP4 is ______ MP3.

小題3:.Which function of MP4 is NOT directly mentioned in this passage?
A.Storing digital audio and video streams.
B.Recording some movies in cinema.
C.Playing TV shows, games and movies.
D.Transferring particular music from a DVD.

A.reasonable to buy other digital products
B.impossible to buy something else
C.a(chǎn) very wise choice to buy an MP4
D.a(chǎn)n exciting experience to buy an MP3

The Golden Gate Bridge, the first sight for many people arriving in the United States by ship, is a well-recognized landmark, which spans(橫跨) the Golden Gate Strait.
The idea for a bridge across the strait had been around for many years, but it was not easy to get the project started. The construction of the bridge finally began in 1933. The construction work set new standards for safety----workers were among the first required to wear hard hats, and an innovative(革新的) safety net saved the lives of nineteen men while the bridge was built. The Golden Gate Bridge was completed in 1937, which was finished ahead of schedule.
Joseph Strauss was the chief engineer in charge of the bridge project. However, he had little experience with the construction of suspension(懸浮)bridges. For this reason, other engineers, architects, and designers made great contributions to the design and construction of the bridge. For example, the bridge owes its art style and unique orange color to the architects Irving and Gertrude Morrow. Charles Alton Ellis was the main engineer on the project and did much of the technical work necessary to build the bridge.
Today, the Golden Gate Bridge has a main span of 4,200 feet and a total length of 8,981 feet, making it one of the longest bridges in the world. The bridge is 90 feet wide, and its span is 220 feet above the water. The towers supporting the huge cables (巨纜) rise 746 feet above the waters of the Golden Gate Strait, making them 191 feet taller than the Washington Monument. About 40 million cars cross the bridge every year. There are foghorns(霧角)to let passing ships know where the bridge is, and aircraft beacons(信號燈)on the tops of the towers to stop planes from crashing into them.
小題1:The purpose of the passage is to _______.
A.describe the construction work of the Golden Gate Bridge
B.introduce the Golden Gate Bridge
C.tell us the history of the Golden Gate Bridge
D.introduce the engineers in charge of the Golden Gate Bridge
小題2:Safety innovations during the construction of the bridge included ________.
A.hardhats and a safety netB.a(chǎn)ircraft beacons
C.foghornsD.a(chǎn)ll of the above
小題3: It can be inferred from the passage that _______.
A.Joseph Strauss was skilled in the construction of suspension bridges
B.it took the construction workers three years to build the Golden Gate Bridge
C.a(chǎn)bout 100 thousand cars cross the Golden Gate Bridge every day
D.the Golden Gate Bridge is the longest bridge in the world
小題4:The underlined word “them” in Paragraph 4 refers to ________.

The Internet has opened up a whole new on-line world for us to meet, chat (聊天) and go where we’ve never been before.
But just as in face-to-face communication, there are some basic rules of behavior that should be followed when online. The basic rule is simple: treat others in the same way that you would want to be treated. Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re going to send, ask yourself: “Would I say this in front of the person?” If the answer is no, rewrite and reread. Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.
If someone in the chat room is impolite to you, your feeling is to fight back in the same manner. But try not to do so. You should either ignore (忽略) the person, or use your chat software (軟件) to stop their messages. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you the right to correct everyone else.
If you do decide to tell someone about a mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those who you have offended (冒犯).
It is not polite to ask others personal questions such as their age, sex, and families. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
小題1:. When you send short messages to a person, you must       .
A.make sure that they don’t do harm to othersB.read them again and again
C.say something good to hearD.repeat them later to the person’s face
小題2:If you are hurt in the chat room by others, you should       .
A.fight back in the same wayB.take them seriously
C.pay no attention to themD.be angry at them
小題3:If a newcomer who communicates on line makes any mistakes, you       .
A.should point them out sharply
B.shouldn’t give any advice unless required by them
C.should say something about them
D.should correct them at once
小題4:This passage mainly tells us       .
A.some rules of Internet communication
B.ways of sending messages
C.rules of the face – to – face communication
D.ways of making friends on the Internet

A rat looked through a crack in the wall to see the farmer and his wife opening a package. What food might it contain? He was alarmed to discover that it was a rat trap (捕鼠夾).
Going back to the farmyard the rat gave a warning: “There is a rat trap in the house, a rat trap in the house!” The chicken raised her head and said: “Excuse me, Mr Rat, I can tell this is a big concern to you, but it is of no business to me. I cannot be bothered with it.”
The rat turned to the pig and told him: “There is a rat trap in the house, a rat trap in the house!”“I am so very sorry, Mr. Rat,” sympathized the pig, “but there is nothing I can do about it but pray. I will make sure that you are in my prayers.”
The rat turned to the cow. She said, “Like wow, Mr. Rat. A rat trap. I am in grave danger. Duh?”
So the rat returned to the house, head down and dejected, to face the farmer’s rat trap alone.
That very night a sound was heard throughout the house, like the sound of a rat trap catching its prey (獵物). The farmer’s wife rushed to see what was caught. In the darkness, she did not see that it was a poisonous snake whose tail the trap had caught. The snake bit the farmer’s wife.
The farmer rushed her to the hospital. She returned home with a fever. Now everyone knows you treat a fever with fresh chicken soup, so the farmer took his hatchet (短柄斧) to the farmyard for the soup’s main ingredient.
His wife’s sickness continued so that friends and neighbors came to sit with her around the clock. To feed them the farmer killed the pig.
The farmer’s wife did not get well. She died, and so many people came for her funeral that the farmer had the cow killed to provide meat for all of them to eat.
So the next time you hear that someone is facing a problem and think that it does not concern you, remember that when there is a rat trap in the house, the whole farmyard is at risk.

In the United States, friendships can be close, constant, intense, generous and real, yet fade away in a short time if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while— then no more. If the same two people meet again by chance, even years later, they pick up the friendship where it left off and are delighted.
In the States, you can feel free to visit people’s homes, share their holidays, or enjoy their lives without fear that you are taking on a lasting obligation(義務(wù)). Do not hesitate to accept hospitality(好客) because you can’t give it in return. No one will expect you to do so for they know you are far from home. Americans will enjoy welcoming you and be pleased if you accept their hospitality easily.
Once you arrive there, the welcome will be full and warm and real. Most visitors find themselves readily invited into many homes there. In some countries it is considered inhospitable to entertain at home, offering what is felt as only home—cooked food, not “ doing something for your guest”. It is felt that restaurant entertaining, shows more respect and welcome. Or for other different reasons, such as crowded space, language difficulties, or family custom, outsiders are not invited into homes.
In the United States, both methods are used, but it is often considered more friendly to invite a person to one’s home than to go to a public place, except in purely business relationships. So, if your host or hostess brings you home, do not feel that you are being shown inferior treatment.
Don’t feel neglected if you do not find flowers awaiting you in your hotel room, either. Flowers are very expensive there; hotel delivery is uncertain; arrival times are delayed, changed, or canceled —— so flowers are not customarily sent as a welcoming touch. Please do not feel unwanted! Outward signs vary in different lands; the inward welcome is what matters, and this will be real.
小題1:In the United States, you will find friendships ______ if circumstances change.
A.die suddenlyB.pass away
C.disappear graduallyD.last forever
小題2:Americans _____ their foreign friends to make a return for their hospitality.
A.a(chǎn)skB.don’t expectC.never allowD.wish
小題3:In some other countries, giving a dinner party at home is considered ______ than in a restaurant.
A.less friendlyB.less hospitableC.more naturalD.more popular
小題4:According to the passage, which of the following is NOT true?
A.Flowers are signs of outward welcome.
B.Flowers are expensive.
C.Flowers are available at all time.
D.Flowers are not necessarily sent to guests.

Boeing said Wednesday that it was entering the space tourism business, an announcement that could bolster(增強)the Obama administration’s efforts to transform the National Aeronautics and Space Administration into an agency that focuses less on building rockets and more on nurturing a commercial space industry.
The flights, which could begin as early as 2015, would most likely launch from Cape Canaveral in Florida to the International Space Station. The Obama administration has proposed turning over to private companies the business of taking NASA astronauts to orbit, and Boeing and Bigelow Aerospace of Las Vegas won an $18 million contract this year for preliminary (初步的)development and testing of a capsule that could carry seven passengers.
Current NASA plans call for four space station crew members to go up at a time, which would leave up to three seats available for space tourists. The flights would be the first to give nonprofessional astronauts the chance to go into orbit aboard a spacecraft launched from the United States. Seven earlier space tourists have made visits to the space station, riding in Russian Soyuz capsules.
“We’re ready now to start talking to possible customers,” said Eric C. Anderson, co-founder and chairman of Space Adventures, the space tourism company based in Virginia that would market the seats for Boeing.
Boeing and Space Adventures have not set a price, although Mr. Anderson said it would be competitive with the Soyuz flights, which Space Adventures arranged with the Russian Space Agency. Guy Laliberté, founder of Cirque du Soleil, paid about $40 million for a Soyuz ride and an eight-day stay at the space station last year. But the possibilities that anyone buying a ticket will get to space on an American vehicle depend on discussions in Congress about the future of NASA.
小題1: Which of the following is most probably a private travel company?
A. Boeing.                     B. Space Adventure.
C. NASA.                       D. Russian Space Agency.
小題2: How many people can be carried along on a capsule to the space station?
A.3. B.4. C.7. D.11.
小題3: What can be inferred from the passage?
A.The American space tourism company is located in Virginia.
B.Russia has already taken lead in working on the space tourism business.
C.NASA has decided to focus less on building rockets because of the financial crisis.
D.In 2015, America would be the first country in the world to run the space tourism business.
小題4:What’s the best title of the passage?
A.Taking NASA Astronauts to Orbit.B.Living in the Space Station Space.
C.Ticket Price under Discussion.D.Boeing Could Fly You to Orbit by 2015.

What makes it rain? Rain falls from clouds for the same reason anything falls to Earth. The Earth's gravity pulls it. But every cloud is made of water droplets or ice crystal(冰晶). Why doesn't rain or snow fall constantly from all clouds? The droplets or ice crystals in clouds are extremely small. The effect of gravity on them is slight. Air currents move and lift droplets so that the net downward amount of water is zero, even though the droplets are moving constantly.
It can be seen that droplets and ice crystals behave somewhat like dust in the air in a beam of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about
without fixed direction. But in fact dust particles(分子) are much larger than water droplets and they finally fall. The average size of a cloud droplet is only 0.0004 inch in diameter(直徑). It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it doesn't fall out of moving air at all. Only when the droplet grows to a diameter of 0.008 inch or larger can it fall from the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size larger enough to fall out is the cause of rain and other forms of precipitation. This important growth process is called "coalescence".
小題1: Ice crystals do NOT immediately fall to Earth because           .
A.they are kept up by air currents
B.most of them change into steam
C.they combine with other chemicals in the atmosphere
D.their electrical charges draw them away from the earth
小題2: The underlined word "random" in line 10 most probably means            .
A.unpredictableB.strictC.independentD.a(chǎn)bnormal
小題3:What can be inferred about drops of water larger than 0.008 inch in diameter?
A.They never occur.
B.They are not affected by the force of gravity.
C.In moving air they would fall to earth.
D.In still air they fall a speed of thirty-two miles per hour.
小題4: How much bigger is the rain drop than a loud droplet?
A.200 times bigger
B.1,000 times bigger
C.100,000 times bigger
D.1,000,000 times bigger

For better or worse, multiple marriages aren't just for actress Elizabeth Taylor (famous for her eight marriages) anymore.
More Americans than ever are tying the knot for the third time or more.
Lynn Y. Naugle, a 53-yeap-old family therapist in New Orleans, says that people's personal needs and desires simply change as their life evolves.
"What functions well in the first part of our lives may not function well in the second or third part of our lives," she explains.The first marriage lasted 21 years, her second marriage five years.Two years ago, she wed for a third time, and she describes this union as an "extremely easy marriage".
Today, at an estimated one of seven weddings, the bride, the groom or both are making that trip down the aisle for at least the third time.That's twice as many as a generation ago, according to the US National Centre for Health Statistics.
In part, the sudden change in multiple marriages is a side effect of the 1970s divorce increase that has supplied an ever expanding pool of divorced singles.Even the simple fact that people are living longer has opened the door to marrying more often.No fault divorce laws (meaning no one is blamed for the failure of the marriage), and cultural changes have also meant there's less pressure than in past generations to stay in a joyless or abusive marriage.
While a single divorce didn't block either Ronald Reagan or Bob Dole from seeking the most highly demanding job in America—the US presidency—modern society still raises an; eyebrow at more than one
marriage mistake.
Indeed, there are signs that attitudes are changing."It's coming out of the closet or becoming more accepted," says Glenda Riley, who wrote a book on the history of divorce in the US."There's still embarrassment on the personal level, while there is growing acceptance on the public level for three or more marriages in a lifetime."
There is no guarantee, of course, that the third time is the best.To the contrary, second and third marriages run an equal or greater risk of divorce than first marriages, which today are given 4 out of 10 odds of failing, and they tend to end more quickly.Divorce statistics show that failed second marriages typically end two years sooner than first marriages, lasting six years on average rather than eight.That leaves some doubly divorced people open for a third try at a relatively young age.
小題1:What does the underlined phrase "tying the knot" (Para.2) mean?
A.Getting married.B.Getting engaged.
C.Having babies.D.Attending funerals,
小題2:What is NOT the reason for the increase in multiple marriages according to the passage?
A.People are healthier and enjoy a longer life than ever before.
B.Many people have become single after a divorce boom in the past years.
C.There is no divorce law restricting people to getting divorced.
D.People have less pressure to leave a joyless marriage.
小題3:What can we learn from the seventh paragraph?
A.Ronald Reagan and Bob Dole failed in seeking the job (the US presidency) because they were divorced.
B.Ronald Reagan and Bob Dole succeeded in seeking the job (the US presidency) because they were not divorced.
C.Modern society accepts multiple marriages completely.
D.There is still prejudice against multiple marriages in modern society.
小題4:Which of the statement is WRONG?
A.Acceptance to multiple marriages is different on personal level and public level.
B.Because second marriages end sooner than first ones, people get married for the third time at a relatively young age.
C.People learn from experience so that a second or third marriage is more stable
D.The first marriage lasts eight year on average.
