1.The first sentence in paragraph 1 means that ______.
A.people may have to go through the hard times
B.the ups and downs of life cannot be avoided
C.life patterns may not be told in advance
D.people may not have a happy life
正确答案：C
解析：第一句：’The ups and downs of life may seem to have no predictable plan.’ 其中 ‘no predictable plan’ 对应选项 C 中的 ‘may not be told in advance’（无法提前预知），强调生活起伏看似无规律可循，即生命模式不可预先确定。A、B 属过度引申；D 无依据。
B.a man is in his best shape in the decade before age 30
C.the peak health period for men is 5 years shorter than that for women
D.the peak health period for women is 10 years longer than that for men
正确答案：C
解析：Paragraph 3 明确指出：’WHEN ARE YOU HEALTHIEST? For men, from 15 to 25; for women 15 to 30.’ 即男性健康峰值期为10年（15–25），女性为15年（15–30），故女性比男性长5年；亦可理解为峰值区间长度差5年。C项表述准确。A错（女性最佳状态始于15，非late 20’s）；B错（原文为’before age 25’，非30）；D错（30−15=15，25−15=10，差值为5年，非10年）。
A.women are as suitable for the competitive job market as men
B.career women may lose their advantages in life expectancy
C.career women usually have lower blood pressure
D.women are fit for any kind of jobs
正确答案：B
解析：Paragraph 4末句：’However, psychologists believe that by entering the competitive job market in increasing numbers, women may eventually give up their statistical advantage.’ ‘statistical advantage’ 指前文所述女性更长的预期寿命（75.9 vs 68.3），即life expectancy优势。B项准确转述此意。A、C、D均属无中生有或过度推断。
5.Which statement is true according to paragraph 6?
A.Creative people usually produce their peak work at the age of 30 to 39.
B.Most Nobel Prize winners reach their peak before their 30’s.
C.Creative people produce work of high quality all their lives.
D.People do not produce fine work in their old age.
正确答案：C
解析：Paragraph 6末句：’creative people continue to produce quality work throughout their lives.’ 与C项完全一致。A以偏概全（原文说’Generally between 30 to 39’，但强调’varies’且’continue to produce’）；B错（原文说’late 20’s and 30’s’，含30年代后期，非’before 30’s’）；D与原文直接矛盾。
A.nowadays wealth flows from younger generations to the older ones
B.nowadays wealth flows from older generations to the younger ones
C.the traditional way of accumulating wealth has been reversed
D.long-established traditions have already been reversed
正确答案：A
解析：Paragraph 2引述Tinker：’the growth of the proportion of people over 50 had reversed the traditional flow of wealth from older to younger generations.’ 即传统是老→少，现在反转为少→老，故A正确。C、D表述模糊且不精准（’accumulating wealth’/’traditions’非原文焦点）；B与原文相反。
D.The increasing number of older people living alone.
正确答案：D
解析：Paragraph 2：’The surging number of older people, many living alone, has also increased demand for property and pushed up house prices.’ D项为原文复现。A、B、C均未被提及或与原文矛盾（如’harder to raise mortgage’）。
