COMMUNITY SERVICE
Community service is a service or activity which is performed by someone or a group of people for the benefit of the public or public organizations.
While volunteers may provide community service, not everyone taking part in a community service program is a volunteer, because not everyone is doing it through their own choice. Sometimes people are asked to do it by:
their government, as part of a citizenship requirement instead of military service;
the courts and other criminal justice punishments;
their school, to meet the requirements of a class, or to meet the requirements of graduation, or, in the case of parents, required to provide a certain number of hours of service in order for their child to be enrolled in a school or sports team.
There are also people providing community service, but they receive some form. of payment in return for their work.
YOUTH COMMUNITY SERVICE
Community service performed by young people, also known as youth service, is intended to strengthen young peoples' senses of civic engagement and community, and to help them achieve their educational, developmental and social goals.
HIGH SCHOOL GRADUATION
Many educational institutions in the United States require students to perform. community service hours to graduate from high school. In some high schools in Washington State, for example, students must complete 60 hours of community service to receive a diploma.
CONDITIONS OF PARTICIPATION
Contribution of service is a condition of enrollment in some programs. Most commonly, parents may be required to serve for their child to be enrolled in a school or sports team.
COLLEGES
Though technically not a requirement, many colleges make community service an unofficial requirement for acceptance. However, some colleges prefer work experience over community service, and some require that their students also participate in community service in order to graduate.

Another example of the world appearing to slow down is when you are hanging on the phone waiting for someone to pick up at the other end. If your attention wanders while you're waiting, then suddenly switches back,you will probably hear what seems like a longer than usual silence before hearing the dialling tone again. For you, time will have momentarily slowed.
To see how our perception of time changes when something new happens, Vincent Walsh and his colleagues put headphones on volunteers and played eight beeps to their right ears. The gap between each beep was exactly i second, except for the gap between the fourth and fifth beeps, which the scientists could make shorter or longer. They altered the length of this gap until the volunteers estimated it was the same length as the other gaps. The researchers found that, on average, people judge a second slightly short, at 955 milliseconds.
In the second part of the experiment, the first four beeps were played to the subjects' right ear, but the other four were then played to their left. Again, the volunteers were asked to estimate when the gap between the fourth and fifth beeps was the same as the others. This time they judged a second to be even shorter at 825 milliseconds long.
Perceiving a second to be much shorter than it is makes you feel as though the world has gone into slow motion, since less happens in that slice of time. Walsh thinks the effect could have evolved to give us a fraction more time to react to potentially threatening events.
Last year, Kielan Yarrow, a British psychologist found a similar effect with vision. When you glance at a clock, the first second will seem longer than it really is.
Yarrow's results showed that time appeared to slow down by a similar amount as Walsh found. Previous studies have shown that cooling the body slows down our perception of time while warming it up has the opposite effect.
After you noticed a car hurtling towards you, you might feel that ______.
A．the world around you had slowed down
B．something bad was going to happen
C．life had suddenly become meaningless
D．people's life was so fragile

High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．
