On March 25,1925 Scottish inventor John Logie Baird gave a demonstration of the televi?sion set,which would change the world,allow us to know what was going on at the other side of the world and change entertainment forever. But,at that time,he just thought it was cool that he could see his face on a screen.
It all began in March 1925 when John Logie Baird gave a demonstration of what can only be described as the first ever television set. All that was seen were images of people on a dark gray screen. Then on January 26 ,1926 he gave the world's first public demonstration of a work?ing television system at his laboratory in London. This was the world's first glimpse at televi?sion.
In 1928 Baird's company broadcast the first transatlantic television signal,between London and New York. This was a great development in television history. In 1931,the first live televi?sion broadcast was made by this stage,the number of television sets was only about 200 in Brit?ain,so it was only the rich and famous who witnessed this great moment in television history.
The television set itself was going through great change. Originally,the first ever television model,the 1928 Baird model C had a screen of only about two and a half inches square;how?ever by 1935,the Baird T5 had a significantly bigger screen and obviously had much better sound quality and picture quality.
By 1939,with the American DuMont 183 it was clear that television was going to revolu?tionize the world,with a picture quality of outstanding clearness for the time. By this stage,television sets were still not accessible by Joe Bloggs,but the number of television sets was rela?tively large; in 1939,7000 television sets were sold.

Failing to drink enough water can make our brain shrink (萎缩) ，experts have warned. Re?search showed that dehydration not only affects the size of the brain but also how it works. Just 90 minutes of steady sweating (出汗) can shrink the brain as much as a year of aging,research?ers believe.
Being short of water,the brain is also forced to work harder to process the same informa?tion. Over days and weeks,lack of liquids could have an impact on performance at work and school,causing exam results to fall. But there is no need to panic,because after a glass of water or two,the brain quickly returns to normal.
A team of scientists from around the UK scanned the brains of teenagers after an hour and a half of cycling. Some exercised in three layers of clothing. Others were much more lightly dressed in shorts and T-shirts. The brain tissue (组织) of those who were wrapped up had shrunk away from their skulls (头骨) .
Researchers Dr. Matthew Kempton and Ulrich Ettinger,of the Institute of Psychiatry at King's College London,said; "It's clear that we saw a general shrinking of the brain tissue. Liquidfilled space in the middle of the brain expanded and there was a comparative shrinking of the brain tissue. The people who lost the most weight had the most shrinkage of the brain. " On average,the amount of shrinkage equated to 14 months of agerelated wear and tear,or the brain shrinking matched two and a half months of Alzheimer's disease (老年痴呆症) .
The sweaty students did just as well when they were asked to play a computer game that tests the ability to plan and solve problems. But the scans showed they used more of their brain to do it,the journal Human Brain Mapping reports.
Professor Ben McGannan of the study's funder,water cooler firm of Water for Work and Home,said：" We strongly believed loss of water was an issue affecting students' performance,but we offered financial support for this research to give us clear evidence. Most importantly,we're seeking a way to get rid of the undesirable impacts and make up enough water effectively,such as drinking beers."
( ) 5. What does the underlined word "dehydration" probably mean?
A. Plenty of water.
B. The inappropriate way to drink water.
C. Great damage done to the brain.
D. Dryness resulting from lack of water.
( ) 6. Without enough water, .
A. it is hard for the brain to think normally
B. the body can't sweat in time
C. people will suffer from ageing
D. the liquidfilled space will disappear
( ) 7. What do Professor Ben McGannan's words suggest?
A. We should make effort to take good care of our brain.
B. More research is needed to solve the brain's loss of water.
C. Drinking beers is the best way to make up water in the body.
D. Students must drink enough water to improve their performance.
( ) 8. What subject is talked in the passage?
A. The brain structure. B. Exercise and the brain.
C. Lack of water in the brain. D. The importance of water.

Years ago,in a small fishing village in Holland,a young boy taught the world about the rewards of unselfish service. Because the entire village lived by fishing,a volunteer rescue team was needed in case of emergency. One night the winds blew heavily,the clouds burst and a sudden storm overturned a fishing boat at sea. In trouble,the crew sent out the S. O. S. The captain of the rescue rowboat team heard the alarm and the villagers gathered in the town square overlooking the bay.
An hour later,the rescue boat reappeared through the fog and the cheering villagers ran to greet them. Falling tired out on the sand,the volunteers reported that the rescue boat could not hold any more passengers and they had to leave one man behind. Even one more passenger would have surely overturned the rescue boat and all would have been lost.
Madly,the captain called for another volunteer team to look for the lone survivor. Sixteen-year-old Hans stepped forward. His mother seized his arm,begging, "Please don't go. Your father died in a shipwreck 10 years ago and your older brother,Paul,has been lost at sea for three weeks. Hans,you are all I have left."
Hans replied, " Mother,this time I have to do my duty. When the call for service comes,we all need to take our turn and do our part. " Hans kissed his mother,joined the team and dis?appeared into the night.
Another hour passed,which seemed to Hans' mother like a century. Finally,the rescue boat moved through the fog with Hans standing up in the bows. Cupping his hands,the captain yelled, "Did you find the lost man?" Barely able to control himself,Hans excitedly cried back, "Yes,we found him. Tell my mother it's my older brother,Paul!"
