IS IT TIME TO GET - MP3

Your computer has been playing music for years, one CD at a time.Now hundreds of songs can be stored in your PC if they’re in the MP3 format.

What is it?

MP3 compresses (壓縮) music into small computer—friendly files.You access MP3 music several ways: Tunes can be downloaded from websites that have converted (轉變) vast music libraries into MP3.Or you can prerecorded CDs into your PC and convert songs in minutes into MP3.Once MP3 music is on your PC’s hard drive, you can play it through your computer’s speakers, “burn” it onto blank CDs or swap (交換) MP3 files with friends using e—mail.

How much?

Software needed to play and convert MP3 music is often free.It is preinstalled (預先安裝)on most new computers or can be downloaded from many websites, including MP3, com.Some MP3 sites are free.Just type at around $50 and can hold hundreds of songs.A blank CD on which you can record music costs about a dollar.

Advantages

MP3 turns your home PC into a jukebox (自動唱機).Tiny MP3 players are the size of a deck of cards, making it easy to take hundreds of songs with you.

Disadvantages

You may find that music at many sites is limited.And some only allow you to listen rather than download offerings.Others let you download music that then can’t be copied to MP3 players.And a growing number of new CDs make it impossible to copy songs to a computer.

科目:高中英語 來源:2013-2014學年廣東省山一高三上學期第二次統測英語試卷(解析版) 題型:閱讀理解

With large and small keyboards everywhere, neither children nor adults need to write much of anything by hand. That’s a big problem. Study after study suggests that handwriting is important for brain development — helping kids get fine motor skills and learn to express and create ideas. Yet the time devoted to teaching penmanship in most schools has shrunk to just one hour a week. Is it time to give up handwriting? Have a look at the link between the brain and penmanship, and you may get the answer.

A test among students in grades 2, 4 and 6 found that they not only wrote faster by hand than by keyboard, but also created more ideas when composing essays with handwriting. And other research shows that the finger movements required to write by hand activate brain areas involved with thought, language, and short-term memory.

A recent Indiana University study had one group of children practice writing letters by hand while a second group just looked at those letters. Then, both groups of kids entered a functional MRI (核磁共振) that scanned their brains as the researchers showed them the same letters. Researchers found that the brain activity in the first group was far more advanced and “adult-like”.

Handwriting also affects other people’s way they think of adults and children. Several studies have shown that the same average essay will score much higher if written with good penmanship and much lower if written out in poor handwriting. These studies have also found that people judge the quality of a person’s ideas based on his or her handwriting. And the consequences are real: On standardized tests with handwritten sections, like the SAT, all essay that is considered hard to recognize gets a big zero.

Studies show that this isn’t only an English-language phenomenon. Chinese and Japanese youths are suffering from “character amnesia”. They can’t remember how to write characters, thanks to computers and text messaging. Some experts fear that Chinese writing and reading are so closely linked in the brain that China’s reading ability as a nation could suffer.

1.According to the passage, it can be learned that ________________.

A. many researches have been done on handwriting

B. essays can’t be composed without handwriting

C. all children write faster by keyboard than by hand

D. most schools are trying to teach more handwriting

2.What does the Indiana University study imply?

A. Children should practice writing letters

B. Handwriting can increase brain activity

C. It’s good for children to enter a functional MRI. 

D. Letters should often be shown to children

3.What does the 4th paragraph mainly talk about?

A. Handwriting affects both adults and children.    

B. Handwriting helps a person write better essays.

C.SAT should be done with good handwriting.     

D. Good handwriting makes a person seem smarter.

4.Which of the following statements is TRUE?

A. Essays written with keyboards will get lower scores.

B. The quality of your ideas depends on your handwriting.

C. Chinese and Japanese youths don’t know how to write.

D. Less handwriting may affect China’s reading ability.

5.The passage tries to tell us that __________________.

A. keyboards are more popular than handwriting     

B. we shouldn’t judge people by their handwriting

C. handwriting is of great importance              

D. it’s time to give up using keyboards

科目:高中英語 來源:2010-2011學年云南省高三第二次月考英語卷 題型:閱讀理解

I had this exchange with my 6-year-old last week.

       Him: Mom, we have to start buying Danimals.

       Me: Why?

       Him: So, I can bring it to |school for lunch.It's yogurt .

       Me: Why do you want it so badly?

       Him: Because Danimals i|s giving away five fantastic Caribbean vacations.

       I had to explain that there was little chance that he would win a vacation.It's a strategy used to encourage kids to beg for artificially-colored (人工著色的) yogurt that costs a lot.

       Marketing follows my kids —and yours—wherever they go .It comes via TV commercials. Store displays and websites are also constantly selling at our kids .But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable.

       Children can begin their day in character clothing.There's even character -themed wall paint available.A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste(牙膏), character soap and shampoo, and a character wash cloth and towel .Then, they can put on character clothing and character shoes.Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?

       Surround kids with enough of the characters and they'll come to believe they need them.Most of us, of course, don't buy all those items.But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty (品牌忠誠)

       At this time of year, parents buy licensed school supplies.With so much marketing around us, it can be tough to stop the tide.

       "One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ."If you decide you want to buck this, it helps to find other people who will do the same thing .That way, if your child says."Everyone's doing it," you can really have a sense of whether everyone is." |

1.From the dialogue between the author and the son, we can infer that ____-

       A.the son likes drinking yogurt a lot.

       B.buying Danimals may win a free tour

       C.the son's school encourages kids to eat yogurt

       D.Danimals in the most popular yogurt among kids.

2.We can learn from th^ passage that     '

       A.character bowls increase kids' appetite.

       B.character-themed wall paint is expensive

       C.household goods are becoming the target of advertisers.

       D.Linn considered character-themed products a foolish marketing strategy.

3.The underlined word "buck" in the last paragraph probably means _____.

       A.support        B.resist           C.advertise            D.learn

4.What does the passage mainly tell us ?  .

       A.Marketing is affecting kids all the time.

       B.Most kids now don't have a happy childhood,

       C.Kids like buying licensed school supplies a lot.

       D.Licensed character produce are doing great harm to kids.
