2、The Guitar
The Museum of Fine Arts in the eastern city of Boston recently began showing a collection of guitars. The exhibit is called Dangerous Curves: The Art of the Guitar. It shows how the instrument developed during the past four centuries.
Probably no other musical instrument is as popular around the world as the guitar. Musicians use the guitar for almost every kind of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.
Music experts do not agree about where the guitar first was played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than a thousand years ago.
Some other experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the seventeen-hundred it became similar to the instrument we know today.
Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played and wrote music for the guitar in the early eighteen hundred. Franz Schubert used the guitar to write some ofhis famous works.
One guitar in the Boston Fine Arts display was played by Les Paul. It is a very old electric guitar. Mister Parl began experimenting with ways to make an electric guitar in the nineteen-thirties. The Gibson Guitar Company began producing its famous Les Parl Guitar in 1952.
The instrument has the same shape and the same six strings as the traditional guitar, but it sounds very different. The guitar has always been important to blues music. The electric guitar Mister Paul helped develop made modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man and his famous guitar.
That man is B-B King. Every blues fan knows that years ago B-B King named his guitar Lucille. Lucille is so important to American music that the Smithsonian Institution in Washington D-C has asked for it. They want to display the large, beautiful black guitar in one of the museums because it is a part ofAmerican culture.
John Denvor is one of the specialists in playing the guitar.

3、Easy Listening
Students should be jealous. Not only do babies get to doze their days away, but they've also mastered the fine art of learning in their sleep.
By the time babies are one year old, they can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake.
To test the theory, Cheour and their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like "oo"; another like "ee" and the third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG (脑电图) recording of the infants brains before and after the session showed that the newborns could not distinguish the sounds.
Fifteen of the babies then went back with their mothers, where the rest were split into two sleep-study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds.
When tested in the morning, and again in the evening, the babies who'd heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all.
Cheour doesn't know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don't "turn off" their cerebral cortex (大脑皮层) while they sleep: The skill probably fades in the course of the first years of life, she adds so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.
The three vowels mentioned in this article are all Finnish sounds.
【单选题】
A.Right
B.Wrong
C.Notmentioned
正确答案:B
答案解析:注意第3段有这样一个短语:something in between,介于前两个元音之间的音。因此,3个元音均是这个边缘上的音,并不是芬兰语种的音。
4、The car
Cars are an important part of life in the United States. Without a car most people feel that they are poor. And even if a person is poor he doesn't feel really poor when he has a car.
Henry Ford was the man who first started making cars in large numbers. He probably didn't know how much the car was going to affect American culture. The car made the United Stated a nation on wheels. And it helped make the United States what it is today.
There are three main reasons why the car becomes so popular in the United States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation. With a car people can go anylace without spending a lot of money.
The second reason cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the country as they are in other parts of the world. Nowadays there is a good system of air-service provided by planes. But it is too expensive to be used frequently.
The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don't like to wait for a bus, or a train or even a plane. They don't like to have to follow an exact schedule. A car gives them the freedom to schedule their own time. And this is the freedom that Americans want most to have.
The gas shortage has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas.
Henry Ford was the first to ____ cars in large numbers.
【单选题】
A.invent
B.sell
C.have
D.produce
正确答案:D
答案解析:依据第2段第1句“Henry Ford was the man who first started making cars in large numbers”。make:制造,等于produce。
5、One Good Reason to Let Smallpox Live
It's now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?
In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). And the last "official" stocks of live Virus bred mistrust of the US and Russia, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines(疫苗). So once again there's a good reason to the virus, just in _____ the disease puts in a reappearance.
How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that's open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn't mean the idea is rejects. If the virus is useful, then let's wrong it the servant of all humanity make not just a part of it.

D.study
