and focus instead on sound, a new study has found.
The study, by researchers at the University of Montreal, involved 7 adults who could see and 12 adults who had lost their vision when they were children. Each participant sat in a room with 16 loudspeakers at different
locations. The room was designed so that there were no echoes. During the experiment, the speakers irregularly produced sounds. Participants had to point to where the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the participants to see which brain structures were working during the
task.
The results showed that five of the blind participants were very good at pointing to where sounds were
coming from. In these people, blood flow increased in the visual cortex- an area at the back of the right side of
the brain. This part of the brain is usually associated with vision.
The other seven blind participants showed no increase in activity in the visual cortex. These people didn"t
do very well at picking out where sounds were coming from. Now, the researchers are looking at whether these people have gained an enhanced sense of touch instead of sound to replace their lost vision.
The scientists say that their study shows how adaptable parts of the brain can be.
B. blind people have a better sense of sound
C. the sense of touch is better among blind people
D. blood flow in the brains of blind people is slower
B. to take down the time each sound lasted
C. to identify the direction the sound came from
D. to detect the number of the loudspeakers.
B. look for the way of enhancing hearing ability
C. find which parts of the brain were functioning
D. expose the relationship between seeing and touching
B. People go blind because of the breakdown of their visual cortex.
C. Most blind people have a better sense of sound than normal people.
D. Human brains can adjust themselves after the loss of a certain function.

more than 140 years in North American museums. The body was carried off the plane in Cairo in a box
covered in Egypt"s flag.
The Michael Carlos Museum gave it back after tests showed it was probably that of the man who ruled
3,000 years ago. The US museum acquired it three years ago from a Canadian museum, which in turn is
thought to have bought it from Egyptian gave robbers in 1860.The mummy was welcomed back home with
songs and military band music during a ceremony at the national museum in Cairo.
Zahi Hawass, head of Egypt"s Supreme Council of Antiquities (文物最高委员会), traveled from the US
with the body and said it would be moved next year to the Luxor Museum in southern Egypt."We are not
100% sure that mummy is that of Ramses I," said Mr. Hawass."But we are 100% sure that it is of a king."
Atlanta"s Michael Carlos Museum acquired the mummy in 1999, but offered to return it after hi-tech
scanning equipment indicated it was likely to be that of Ramses I. The museum website said it had been
acquired from the Niagara Falls Museum. It is thought a Canadian collector bought the mummy for the
Niagara Falls Museum around 1860 from an Egyptian family which had came across a tomb filled with royal
mummies at a site near Luxor.
Mr.Hawass praised the handover as"a great, civilized gesture". And he appealed to other world museums
to return Egypt"s antiquities, particularly the Rosetta Stone in the Britain Museum and the Bust of Nefertiti in
the Berlin Museum.

C. the Niagara Falls Museum
D. a Canadian Museum
a. The mummy returned home.

D. c-d-b-e-a
B. Niagara Falls Museum is an American museum.
C. Buying the mummy from the Egyptian family was a civilized gesture.

basically equipped to hear and distinguish every possible language and dialect, but once they reach 6 months
old, they begin to focus on the particular sounds that exist in the languages that they"re exposed to. In this
way, kids will naturally and automatically be bilingual (双语的) if they hear multiple languages on a daily
basis when they are still babies..
One lady told me of her son who grew up in a very multi-cultural community working at a resort. He
would naturally and easily switch from Dutch, to French, to Italian, German and English depending on who
he was talking to. Of course that"s an extreme case, but it"s completely possible and easy.
It" s not true that they will get mixed up by learning multiple languages. They may mix them up purposely
simply because certain words or expressions are easier, but they won"t develop any permanent language
disabilities. Quite the contrary, bilingual children have been shown to be as much as a year more advanced in
learning ability development for 2 and 3 years olds.
Some kids who simply aren"t gifted at learning languages, just as some aren"t gifted at sports or music,
will find it difficult to continue schooling in a foreign language. In that case, it may be better not to continue
with the foreign language school. Still, it will have been an excellent opportunity for Grade One. Perhaps for
Grade Two you could try a bilingual school.
In any case, learning even a small amount of a foreign language, maintaining the ability to hear and
pronounce it by listening to music and movies will keep a foundation for later learning. Knowing a second
language can be a great benefit for gaining employment.
B. Kids are able to learn multiple languages.
C. Kids should be exposed to the native language.
D. Kids enjoy all kinds of different dialects.
B. He was learning some different languages.
C. He could talk with many people at the same time.
D. He was working in a multi-community.
A. Mixing up different languages.
B. Distinguish different dialects.
C. Developing learning ability.
D. Developing language disabilities.
B. Encourage them to remain in Grade One
C. Let them remain in the foreign language school.
D. Send them to a bilingual school later.
area of plant growth the increase is the result of weather conditions.
Eight scientists from across the United States did the study. The space agency NASA and the Department
of Energy paid for it. The findings were published in the magazine Science.
The researchers spent one and a half years examining weather satellite information. The information was
recorded from 1982 to 1999.That period was one of the warmest on record. Researchers found that rainfall
generally increased during that time.
The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists
used that information to estimate what is called net primary production. This is total amount of carbon stored
in land plants.
The scientists report a 6% increase in stored carbon since 1982.They say gains were high in equatorial
areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net
primary production.
Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud
cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through.
More sunlight meant increases in photosynthesis (光合作用).That is the process by which plants use energy
from sunlight to produce the chemicals they need to grow.
Northern Canada, the north-central United States and northern Europe were second in increased plant
growth.Ramakrishna Nemani says a rise in temperature helped plants there.
All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists
also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni
of Boston University in Massachusetts, another study scientist says humans use about half the net primary
production on Earth. And he notes that the world population grew by 36% during the period of time studied.
B. The Department of Energy of the US.
C. Ramakrishna Nemani in Missoula.
D. Ranga Myneni in Massachusetts.
B. Regional features.
C. Seasonal variation.
D. Weather conditions
B. Because plants could get more rainfall.
C. Because plants could enjoy cooler air.
D. Because plants suffer less from natural disasters.
B. Rainfall decreased little by little.
C. World population grew by 25%.
D. Stored carbon increased by 6%.
different home schooling teachers discuss history, I get the idea that there may be different reasons for
teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons
for studying history.
The major reason I see for studying history is that we can learn from the past. I am convinced that the
world would be a much better place if more people understood the successes and failures of the past and
the things that made these successes and failures. However, as the unfortunately true statement goes "the
one thing we seem to learn from history is that we don"t seem to learn from history." Perhaps at least in
teaching history, to my children I can do a small part in changing this.
A second major reason for studying history is that it is hard to understand the current political climate
in the absence of an understanding of its historical context. We can- not even understand why we are and
where we are without history, much less (更不必说) try to figure out where we are going or how we
should get where we want to be.
I teach my children history, for one more reason. I purchased a set of historical audio (录音机) tapes
for our children. My seven-year-old son listened to them over and over. It was my hope that he would
become inspired by the accomplishments of people like the Wright brothers to accomplish things by
himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr.
if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what
he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against
the things that he stood for.
B. Many people fail to make good use of history and make the same mistakes.
C. Many people feel it hard to understand history.
D. Many people have no interest in studying history.
B. it helps us realize the importance of historical events
C. it helps us understand why things are the way they are
D. it helps people accept the present situation where they live
B. Some negative reasons for studying history.
C. How to get more people to study history.
D. Some bad historical figures.
B. show the importance of history in politics
C. explain the reasons why children study history
D. introduce the writer" s own way of teaching history
or her second year of high school is required to take a class in driver"s education. However, unlike other
courses, it is not given during the regular school year. Instead it is a summer course.
The course is divided up into two parts: class time for learning laws and regulations, and driving time to
practise driving. Class time is not unlike any other class. The students study the basic traffic laws from a text
to pass the written driving test that is given to anyone who wants to get a driver"s license.
Driving time is a chance for the students to get behind the wheel (steering wheel) and practise starting
steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers (操作) required
to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups
of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets
half an hour driving time per outing. The instructor and "driver" sit in the front seats and the other three
students sit in the back.
After the student has passed the driver"s education course and reached the appropriate age to drive (this
age differs in every state but in most cases the person must be 16 years old), they can go to a designated (指
定的) state office to take their driver"s test, which is made up of an eye examination, a written test, and a
road test. The person must pass all three tests in order to be given a driver"s license. If the person did well in
his or her driver"s education class, he or she will pass the test with flying colors and get a driver"s license.
B. is given to anyone wanting to get a driver"s license
C. is carried on at the same time as other courses
D. is offered to all the students of Grade 2 in high schools
B. has two sets of brakes
C. is big enough to hold five persons
D. can"t run very fast
B. get half an hour driving
C. drive for two hour blocks of time
D. go out driving for twelve times
B. They must be 16 years of age.
C. They should go to have their driver"s test.
D. They ought to do well in their driver"s course.
B. quickly
C. colorfully
D. successfully
