Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during
World War I in Australia. During the world wars, DST was used for the late summers beginning January
1917 and 1942, and the full summers beginning September 1942 and 1943.
In 1967, Tasmania experienced a drought (干旱). The State Government introduced one hour of daylight
saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the
Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian
Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South
Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so
until 1989.
Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics
or festivals (节日). For example, in 1992, Tasmania extended (延长) daylight saving by an extra month while
South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving
plans were made during the Sydney 2000 Olympic Games.
The differences in daylight saving in Australia continue to cause serious problems in transport and many
other social activities. It also reduces the number of hours in the working day that are common to all centers
in the country. In particular, time differences along the east coast cause major differences, especially for the
broadcasters of national radio and television.

is no new Harry Potter. J.K. Rowling"s wizard is not alone: the past decade has been a harvest for good
children"s books, which has set off a large quantity of films and in turn led to increased sales of classics
such as The Lord of the Rings.
Yet despite that, reading is increasingly unpopular among children. According to statistics, in 1997 23%
said they didn"t like reading at all. In 2003, 35% did. And around 6% of children leave primary school each
year unable to read properly.
Maybe the decline is caused by the increasing availability of computer games. Maybe the books boom has
affected only the top of the educational pile. Either way, Chancellor Gordon Brown plans to change things for
the bottom of the class. In his pre-budget report, he announced the national project of Reading Recovery to
help the children struggling most.
Reading Recovery is aimed at six-year-olds, who receive four months of individual daily half-hour classes
with a specially trained teacher. An evaluation earlier this year reported that children on the scheme made 20
months" progress in just one year, whereas similarly weak readers without special help made just five months"
progress, and so ended the year even further below the level expected for their age.
International research tends to find that when British children leave primary school they read well, but read
less - often for fun than those elsewhere. Reading for fun matters because children who are keen on reading
can expect lifelong pleasure and loving books is an excellent indicator of future educational success. According
to the OECD, being a regular and enthusiastic reader is of great advantage.

of the television have been devised in the UK.
The shoes-named Square Eyes-contain an electronic pressure sensor and a tiny computer chip to
record how many steps the wearer has taken in a day. A wireless transmitter passes the information to
a receiver connected to a television, and this decides how much evening viewing time the wearer deserves,
based on the day"s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British
teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University
in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I
wanted to tackle that with my design."
Once a child has used up their daily allowance gained through exercise, the television automatically
switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts
of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours
of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV
time.
Existing pedometer (计步器) normally clip onto a belt or slip into a pocket and keep count of steps by
measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking.
But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of
effort," she says. "That was one of my main design considerations."

hopeless about it. Can you learn to read better, or must you agree that nothing can be done about it?
To be sure, people are different. You cannot to do everything as well as certain other people do. It al the
students in a class tried out for basketball, some would be very good players; others would be very poor;
and many would be in between. But even the very poor players can become much better players if they are
guided in the right way, and with plenty of practice. It is the same with reading. Some seem to enjoy reading
and to read well without any special help. Others find reading a slow and tiring job. In between, there are all
degrees of reading ability.
Many experiments have shown that just about every poor reader can improve his reading ability. In these
experiments, the poor readers were given tests of reading ability. After some of the causes of their poor
reading were discovered, they were given special instruction and practice in reading. After a few months,
another test of the same kind was given. In nearly all cases, these people had raised their reading scores.

thought that this couldn"t be helped, but new studies show that people of any age can train their brains
to work faster. "Your brain is a learning machine," says University of California scientist Dr. Michael
Merzenich. Given the right tools, we can train our brains to act like they did when we were younger.
All that"s required is the practice designed just for the purpose: a few exercises for the mind.
Merzenich has developed a computer-based training method to speed up the process(过程) in which
the brain deals with information (positscience.com). Since much of the data we receive comes through
Over the course of training, the program starts asking you to distinguish (辨别) sounds (between "dog"
and "bog", for example) at an increasingly faster speed. It"s a bit like tennis instructor, says Merzenich,
hitting balls at you ~faster and faster to keep you challenged (受到挑战). You may start out slow, but before
long you"re pretty quick.
The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic. If
you ask your brain to learn, it will learn. And it may even speed up while in the process.
To keep your brain young and plastic you can do one of a million new activities that challenge and excite
you: playing table tennis or bridge, doing crossword puzzles, learning a language.... "When it comes to
preventing ageing, you really do "use it or lose it"," says Barbara Sahakian, professor at Cambridge University.

D. People believed nothing could stop the brain slowing down.
B. People should use the brain to stop it from ageing.
C. The training of the brain should start at an early age.
D. It"s necessary to take part in as many activities as possible.
out, they attend to their feelings. As thoughts go through their minds. they let them go. Breathe. Let go.
Breathe. Let go.
According to a recent study at the Insight Meditation Society in Barre, Massachusetts, three months of
training in this kind of meditation causes a market change in how the brain allocates (分配) attention. It
appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly
changing things and events in the outside world. Expert mediators are better than other people at catching
such fast-changing stimuli (刺激), like facial expressions.
The study provides evidence for changes in the workings of the brain with mental training. People can
learn and improve abilities of all sorts with practice. everything from driving to playing the piano. The study
has shown that meditation is good for the brain, It appears to reduce pressure and promote a sense of
well-being.
In an experiment, 17 volunteers with no meditation experience in the experimental group spent three
months meditating 10 to 12 hours a day. A control group also with no meditation experience meditated for
20 minutes a day over the same period. Both groups were then given the tests with two numbers in a group
of letters. As both group looked for the numbers, their brain activity was recorded.
Everyone could catch the first number. But the brain recordings showed that the less experienced
mediators tended to grasp the first number and hang onto it, so they missed the second number. Those with
more experience gave less attention to the first number. as if letting it go, which led to an increased ability
to grasp the second number, This shows that attention can change with practice.
Just ask Daniel Levision, who meditated for three months as part of the study. " I am a much better
listener," he said. "I do not get lost in my own personal reaction to what people are saying."
