每日翻译练习[十六]

GOD STILL READ ENGLISH…..

 

A person’s intake of refined sugar and of foods that break down into sugars during digestion is the dietary source of virtually all of the glucose (a type of sugar) that reaches that person’s bloodstream. Coffee, however, which itself does not break down into sugars during digestion, sometimes causes a person’s blood-glucose level to rise dramatically, even if the coffee is consumed without cream or any
sweeteners.
 
Which of the following, if true, best helps to explain coffee’s effect on blood-glucose levels as it is described above?

  • People often drink coffee after a meal consisting of several types of foods that themselves rapidly break down into sugars during digestion.
  • Drinking more than two cups of coffee in an hour increases a person’s level of stress, and the body reacts to stress by releasing stored glucose into the blood.
  • People who eat very few foods that contain refined sugar often have higher blood-glucose levels than people who eat many such foods.
  • For many people, the consumption of one piece of chocolate cake has the same stimulating effect as one cup of plain coffee.
  • People with sedentary office jobs are more likely to drink large amounts of coffee and to have higher blood-glucose levels than are people with jobs requiring constant physical activity.

读题:人直接吸收的糖及人在消化过程中由食物分解而成的糖是进入人血管的葡萄糖的来
   源。但是,虽然咖啡在消化过程中并不分解为糖,有时候也可以使人体内的葡萄糖
   浓度急剧上升,尽管喝咖啡时并没有吃奶油或其它甜食。
问题:下面那一个,if true,最帮助解释咖啡对葡萄糖浓度的作用?
 
A.在吃过饭后,这顿饭是由几种在消化时迅速分解为糖的食物组成的,人们常常喝咖啡。(喝咖啡只是一种习惯,起作用的还是饭中的食物)
B. 一小时内喝超过2杯咖啡,就会增加人的压力程度,人体对压力情绪的反应是把储存的葡萄糖释放到血液中。(介绍咖啡是如何起作用的) 
C.极少吃含糖食物的人往往比喜欢吃含糖食物的人的血浓度还要高。
D.对于许多人来讲,吃一块巧克力蛋糕与喝杯咖啡具有同样的刺激效果。
E.常坐办公室的人与从事体力劳动的人相比,前者更有可能喝大量的咖啡,含糖浓度更高

答案:(B)

The use of nets at beach resorts to protect swimming areas from sharks has been criticized by environmentalists because the nets needlessly kill thousands of marine animals annually. However, environmentalists have recently discovered that an electrified cable buried beneath the periphery of swimming areas causes sharks to swim away while harming neither humans nor marine life. Hence, by installing such cables, resort communities will be able to maintain tourism while satisfying environmentalists’ concerns.
 
Which of the following, if true, most seriously weakens the argument?

  • Many seaside resort communities where sharks have never been sighted nonetheless plan to install the new technology.
  • Tourism at resorts where sharks have been sighted has suffered only slightly despite the fact that most people claim to fear sharks.
  • Most tourists are unlikely to visit beaches where swimmers cannot actually see the barrier that protects them from sharks.
  • The buried cable is not the only innovation approved by environmentalists that is known to be successful in repelling sharks without harming them.
  • The electrical current produced by the buried cable repels many kinds of fish but not the marine mammals that are a tourist attraction at many resorts.

读题:
环保人士批评海滨浴场用网将泳区与鲨鱼隔开的作法。因为每年这种网无谓地杀死了数
以千计的海洋生物。最近环保人士发现将电缆埋在泳区四周的下面,sharks就会自动游
开,这样既不伤人又不会伤害海洋动物。所以,安装上这种电缆后,泳区既能维持旅游
业,同时又能满足环保人士的要求。
 
问题:下面那一个,if true,最严重削弱上面的论述?

 
A. 许多从未目击鲨鱼的海滨浴场也计划安装电缆。
B. 尽管许多人声称害怕鲨鱼,有鲨鱼出没的地区的旅游业受影响并不大。
C. 一些游泳的人看不到将他们与鲨鱼隔开的障碍之后,就不再光顾这些海滩了
D. 在环保主义者认可的能成功驱除sharks同时又不伤害他们的办法中,地下埋电缆并非唯一办法。
E. 埋在地下的电缆产生的电流吓跑了许多鱼,但并没有吓走吸引游客的海洋哺乳动物。

答案:(C)

注:双击‘答案’后面的括号,就可以看到正确答案
