[不定项选择题]资料：Stress is a common factor in life. Children experience stress from school, new social situations and simply growing up. Adults feel the stress of working, paying bills, raising kids and maintaining households. Seniors also feel stress, even though some may have retired, raised their children and paid off their homes. Certain amounts of stress are a part of life for people of all ages.
For seniors, stress has the potential to be especially overwhelming. This type of tension in older adults has unique contributing factors, such as the loss of an elderly spouse or friends. Living alone can increase the sense of isolation. Sometimes the simple tasks of everyday life can cause stress in those who experience physical or medical limitations. The effects of stress can sometimes exacerbate health conditions from which some seniors suffer, causing additional worry.
Stress can be detected in various ways. You may follow the five most common ways to find out if a loved one’s stress is cause for concern:
1. Changes in eating habits, such as over-eating or loss of appetite, can be caused by overwhelming stress.
2. Mood swings due to stress may present in increased irritability, general sadness or depression.
3. Memory issues may arise in the form of increased forgetfulness of names, places or other things that normally come naturally. Lack of concentration may become a problem. Some seniors may exercise poor judgment, such as excessive spending when they are already on a limited budget.
4. Physical signs of stress can include body aches and pains or increased episodes of illness. Changes in sleeping patterns—either trouble falling asleep or interrupted nighttime sleep—can signal significant stress.
5. Seniors experiencing overwhelming stress often isolate themselves from others, refusing to socialize or participate in activities they used to enjoy.
What does the word “exacerbate”（Line 4, Paragraph 2） probably mean?
A.Affect
B.Improve
C.Intensify
D.Worsen

High Stress May Damage Memory
According to a report issued in May 1998,elderly people who have consistently high
blood levels of cortisol (皮质醇）don't score as well on memory tests as their peers with
lower levels of the stress hormone. What's more,high levels of cortisol are also associated
with shrinking of the hippocampus（海马区）,a region of the brain that plays a key role in
learning and memory.
The findings 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
(肾上腺的）stress hormones may promote hippocampal aging in normal elderly humans",
write Nada Porter and Philip Landfield.Cortisol is a hormone released in response to stress
by the adrenal glands（腺）,which sit on top of the kidneys(肾）.
Over a 5-to 6-year period,Dr. Sonia Lupien and his colleagues measured 24-hour
cortisol levels in 51 healthy volunteers,most of whom were in their 70s.
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 in
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 other brain regions.
The results suggest that“…brain aging can be accelerated by levels of adrenal
hormones that are not generally regarded as pathological（病态的）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 the
hippocampus."
The research conducted by Porter and Landfield shows that
A.the levels of adrenal hormones have nothing to do with brain aging.
B.changes in the levels of adrenal hormones can affect brain aging.
C.chronic stress may strengthen one's memory.
D.the rate of brain aging always remains stable.
