       If you’re a male and you’re reading this, congratulations! You’re a survivor. According to statistics,you’re more than twice as likely to die of skin cancer than a woman,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term,about 78 years for men in Australia,you’ll die on average five years before a woman.

There're many reasons for this--typically,men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.

“Men aren't seeing doctors as often as they should,” says Dr. Gullotta.“This is particularly so

for the over-40s, when diseases tend to strike. According to a recent survey, 95%of women aged between 15 and early 49s see a doctor once a year, compared to 70%of men in the same age group.

“A lot of men think they’re unbeatable,”Gullotta says.“They only come in when a friend drops dead on the golf course and they think, Geez, if it could happen to him …”

Then there’s the ostrich(鸵鸟)approach.“Some men are scared of what might be there and would rather not know,” says Dr. Ross Cartmill.

“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups.

“Prevention is cheaper in the long run than having to treat the diseases.Besides, the final cost is far greater,it’s called premature death.”

小题1:Why does the author congratulate male readers at the beginning of the passage?

A.They can live longer than they expected.

B.They are sure to enjoy a longer and happier life.

C.They have lived long enough to read this article.

D.They are more likely to survive serious diseases now.小题2:Which of the author’s statements is the most important reason that men die five years earlier on average than women according to the passage?

A.Men drink and smoke much more than women.

B.Men don’t seek medical care as often as women.

C.Men are more likely to suffer from deadly diseases.

D.Men aren’t as cautious as women in face of danger.小题3:Which of the following best completes the underlined sentence “Geez, if it could happen to him…” (in Para 4) ?

A.it could happen to me,too.

B.it would be a big misfortune.

C.I should avoid playing golf.

D.I should consider myself lucky.小题4:What does Dr.Ross Cartmill mean by“the ostrich approach”(in Para 5)?

A.A casual attitude towards one’s health conditions.

B.A new treatment for certain psychological problems.

C.Refusal to get medical treatment for fear of the pain involved.

D.Unwillingness to find out about one’s disease because of fear.

实验题

植物的新陈代谢受外部环境因子(如光、温度)和内部因子(如激素)的影响,研究内外因子对植物生命活动的影响具有重要意义。

(1)下图表示野外松树(阳生植物)光合作用强度与光照强度的关系。其中的纵坐标表示松树整体表现出的吸收CO2和释放CO2量的状况。

请分析回答:

①.当光照强度为b时,光合作用强度____________________。

②.光照强度为a时,光合作用吸收CO2的量等于呼吸作用放出CO2的量。如果白天光照强度较长时期为a,植物能不能正常生长?为什么?___________________________。

③.如将该曲线改绘为人参(阴生植物)光合作用强度与光照强度关系的曲线,b点的位置应如何移动,为什么?_______________________________。

(2)有人设计了下列实验,试图证明“生长素(IAA)在植物体内的运输,主要是从植物形态学上端(顶端)向下端(末端)运输,而不能倒转过来运输(如生长素只能从胚芽鞘的上端向下端运输)。”

一、材料、用具:胚芽鞘、琼脂、刀片等

二、方法、步骤与结果

(一)制备琼脂块

(二)取一段胚芽鞘中间部分,上面放含IAA的琼脂块,下面放空白琼脂块

(三)取步骤(二)下面琼脂块(a)的一部分放在去尖的胚芽鞘一侧

三、结论:以上实验证明了“生长素(IAA)在植物体内的运输,主要是从植物体形态党龄端(顶端)向下端(基端)运输,而不能倒转过来运输”。

我们认为,仅用该实验步骤(一)、(二)、(三)还不足以严密论证以上结论,请在上述实验的基础上补充相应的实验方法、步骤和结果。
