9.By the window         with dark glasses,         seemed to be waiting for someone.(  )
A.a young man stood,whoB.did a young man stood,that
C.a young man did stand,whichD.stood a young man,who

分析 在窗边站在一个带墨镜的年轻人,他似乎在等某人.

解答 答案是D.本题考查倒装和定语从句;题干中表示地点的介词短语by the window放在句首,句子用完全倒装;第二句是以a young man 为先行词的定语从句,从句中缺少主语,故用who;所以答案是D.

点评 本题考查倒装,要积累相关倒装的规则,分清完全倒装和部分倒装;最后结合语境判断.

4."Within the heart there are millions of cells (细胞) that enable it to beat.Between the age of 20and 70,one-third of those cells die and are not replaced in men,"said Goldspink."This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells.A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.
"This gender difference might just explain why women live longer than men,"said Goldspink.They studied more than 250healthy men and women between the ages of 18and 80,focusing on healthy persons to remove the confusing influence of disease."The team has yet to find why ageing takes a greater loss on the male heart,"said Goldspink.
The good news is that men can improve the health of their heart with regular exercise.Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
