[单项选择] The symptoms of Alzheimer’’s disease were long dismissed as normal consequences of human aging, but in the 1980’’s the disease came to be recognized as the most common cause of intellectual deterioration in the elderly and middle-aged. It is characterized by the death of nerve cells in the cerebral cortex -- the part of the brain involved in complex function.
The major debilitating symptoms of Alzheimer’’s disease include serous forgetfulness -- particularly about recent events--and confusion.

[单项选择]Everyone talks about the "five" senses of human beings. It is true that we get our information about the outside world from our sense of sight, hearing, smell, touch and taste. Researchers tell us that the sense of sight--our visual sense--gives us up to 80% of what we know about the world outside bodies, while the senses, the auditory (hearing), the olfactory (smell), the tactile (touch), and the gustatory (taste) bring into our brains information about the other twenty percent of what is happening. But there are two other senses that we cannot get along without, though they are seldom noticed. There are the sense of balance, without which we would act like a drunk after a heavy drink, and the kinesthetic (动觉的) sense, which gives us our ideas about our own motion.
Our own movements are a result of ______ .
A. the five senses
B. the kinesthetic sense
C. the visual sense
D. the tactile sense
[单项选择]"Family" is of course an elastic word. But when British people say that their society is based on family life, they are thinking of "family" in its narrow, peculiarly European sense of mother, father and children living together alone in their own house as an economic and social unit. Thus, every British marriage indicates the beginning of a new and independent family-hence the tremendous importance of marriage in British life.
For both the man and the woman, marriage means leaving one’s parents and starting one’s own life. The man’s first duty will then be to his wife, and the wife’s to her husband. He will be entirely responsible for her financial support, and she for the running of the new home. Their children will be their common responsibility and theirs alone. Neither the wife’s parents nor the husband’s, nor their brothers or sisters, aunts or uncles, have any right to interfere with them-they are their own masters.

{{B}}TEXT D{{/B}}
1)People with diabetes have too much
sugar in their blood, so a drug that lowers blood sugar ought to be a good
treatment, right

Avandia, or rosiglitazone, which was approved in 1999．it lowers blood sugar, and

disease is a major complication of diabetes, so a drug that could make the risk
