GRE阅读题目解析:糖尿病并发症

2017-04-13 09:17:00来源:网络

  P2

  1

  The complications frequently accompanying diabetes, such as impairment of vision and of kidney function, are now thought to result from the lack of continuous control of blood glucose concentrations.

  糖尿病经常伴随一些并发症,如视力和肾功能受损,现代观点认为这些并发症缘于血液内葡萄糖浓度长期失控。

  (concentration 集中,全神贯注,在生化语境中,作浓度。)

  2

  The healthy pancreas, in response to increases in blood glucose concentration, releases small quantities of insulin throughout the day and thereby maintains the concentration within physiological limits (normoglycemia).

  健康的胰腺,能够根据血液中葡萄糖浓度的上升,在一天中分多次释放少量的胰岛素,以此保持葡萄糖浓度低于生理界限(血糖正常状态)。

  3

  But the diabetic generally receives only one large dose daily.

  但糖尿病人通常每天只释放一次大剂量(胰岛素)。

  4

  The diabetic‘s blood glucose concentration can thus fluctuate greatly during the interval between doses, and it has been suggested that the complications result from the periods of high concentrations of blood glucose (hyperglycemia).

  因此,在这些大剂量释放胰岛素的间歇,糖尿病人的血糖浓度可能急剧波动,而这也暗示着,并发症发生在这些血液葡萄糖浓度过高的时段(血糖异常状态)。

  5

  Many investigators thus believe that restoration of normoglycemia might halt the progression of such complications and perhaps even reverse them.

  很多研究者因而相信恢复血糖正常可能停止这些并发症的发展,甚至也许可以使病情逆转。

  For the following question, consider each of the choices separately and select all that apply

  4. The author provides information that would answer which of the following questions?

  □A What is hyperglycemia?

  □B What is one cause of hyperglycemia?

  □C What are some of the organs that can be adversely affected by hyperglycemia?

  选 ABC

  A 句 4 解释了什么是 hyperglycemia。

  B 句 3、4 ,每天一剂大量导致了血糖失控。

  C 句 1 ,眼睛,肾。

  5. According to the passage, widely spaced doses of insulin can cause.

  (A) reversal of normal kidney function

  (B) delay in the onset of diabetes

  (C) radical changes in the concentration of blood glucose

  (D) restoration of normoglyccmia

  (E) marked variations in the islets of Langerhans

  选 C

  widely spaced 间隔大的,符合糖尿病患者的情况。radical 剧烈的,激进的。

  A 恢复肾功能

  B 延缓糖尿病发病

  D 恢复血糖正常
