Have you ever felt your mind falling into disorder after a
sleepless night? You couldn't come up 21
an
original thought no matter how hard you tried.
You were probably 22
if you
thought that was caused by a lack of sleep. Dr. Horne, a sleep
researcher in England , studied 24 college students. One group got
their normal eight hours of sleep . The other group didn't get the
smallest amount of sleep --they stayed 23
all night.
The next day, Dr. Horne tested the students. He asked them
questions that required 24
and
original thinking. One of the questions was "How many uses can a
cardboard box be put to ?"
The result? The wide-awake students did well on the test .The tired
students did 25
.
Research has already shown that tired people can do OK on tests of
habitual thinking, like simple addition. But Dr. Horne tested
creative thinking only.
As part of his study, he offered an amount of money as a reward to
the sleepy students if they did well. But even this encouragement
wasn't enough to help the students conquer their tiredness. They
did poorly. Dr. Horne believes that the part of the brain where
thinking takes place may get worn out during waking hours. Sleep
may help to repair the brain. "Without any sleep, "he emphasized,
"even if you pay closer attention, you cannot do
better."
This study gives people something to think about, especially people
like hospital workers who must stay awake all night and then make
quick decisions.

Few Americans remain in one position or one place
21
a lifetime. We move
from town to city to suburb, from high school to college in
a 22
state,
from a job in one region to a better job elsewhere, from the home
where we raise our children to the home where we plan to live in
retirement. With each move we are 23
making new
friends, who become part of our new life at that time.
For many of us summer is a special time for forming new
friendships. Today millions of Americans vacation abroad, and they
go not 24
to see new
sights but also with the hope of meeting new people. No one really
expects a vacation trip to produce a close friend, but the
beginning of a friendship is possible.
The word friend can be 25
to a wide
range of relationships to someone one has known for a few weeks in
a new place, to a fellow worker, to a childhood playmate, to a man
or woman, to a trusted confidant (知已).

"Body clocks" are biological(生物的) methods of controlling body
activities. Every 21
thing had
one. In humans, a body clock controls normal periods of sleeping
and waking. It controls the times when you are most likely to feel
pain. Eating, 22
and
exercising at about the same time each day will help keep body
activities normal. But changes in your life-a new job, for
example--destroy the
balance(平衡) and thus cause health problems. You
could have difficulty sleeping, for example. Scientists suggest
that early afternoon is the best time of day 23
physical
exercise. They say we are stronger and faster then. Later, about
four o'clock, most people feel tired because of the drop of
sugar(糖) level in the blood. Early afternoon
also is a good time to do tasks involving memory and mathematics.
If you must study, however, do it just 24
going to
sleep at night. Scientists say you are more likely to remember
information when there is a short delay between study and bed. Body
clocks control all the activities from day to day. They also
produce changes 25
every
ninety minutes during the day. At the end of such a time period,
our ability to think hard begins to weaken. That is the time we are
most likely to daydream. Within fifteen minutes, we are ready to go
back to what were doing.

Australia is 21
as large
as the United States, but most of it is too dry for people to live
in. Around the edge of this huge dry part are large sheep and
cattle farms. A few of them are as large as the smallest states in
America. Often the 22
neighbors
are many hundred miles away.
The two-way radio is very important to people who live on these
great Australian farms. It works much like a telephone. A person
can listen 23
someone
else talk and give an answer.
When these radios first came into use, the Australian government
set up for them in some areas. At a certain time each day, the boys
and girls turn 24
their
radios and listen to teachers in cities miles away. Families on the
large farms wanted to give news to their neighbors. "Round
Robin(知更鸟) Talks" by radio were started to
keep families in touch with each other. They could talk about who
was going away or who was sick or who was getting married. The men
could talk about their sheep and cattle and how much money the
markets would pay 25
them. In
many ways the radio became a newspaper for the farm people of
Australia.
