问题 单项选择题

某学校最近进行的一项关于奖学金对学习效率促进作用的调查表明:获得奖学金的学生比那些没有获得奖学金的学生的学习效率平均要高出25%。调查的内容包括自习的出勤率、完成作业所需要的时间、日阅读量等许多指标。这充分说明,奖学金对帮助学生提高学习效率的作用是很明显的。
以下哪项,如果为真,最能削弱以上的论证

A.获得奖学金通常是因为那些同学有好的学习习惯和高的学习效率。
B.获得奖学金的同学可以更容易改善学习环境来提高学习效率。
C.学习效率低的同学通常学习时间长而缺少正常的休息。
D.学习效率的高低与奖学金的多少的研究应当采用定量方法进行。
E.没有获得奖学金的同学的学习压力大,很难提高学习效率。

答案

参考答案:A

解析:因果倒置,不是题干所认为的“奖学金”导致了“学习好”,而是因为学生的学习效率高,学习好,所以获得了奖学金。

A blocked airway(呼吸道) can kill someone in three to four minutes, but it can take more than eight minutes for an ambulance to arrive. So a simple procedure such as opening someone's airway can save their life while they're waiting for emergency medical help. This means you're more likely to give first aid to someone you know than a stranger.

There are many misconceptions(误解) surrounding first aid. Below are the ‘most popular’ ones with details of what you should do.

You should put butter or cream on a burn. The only thing you should put on a burn is cold water - keep the butter for cooking. Put the affected area under cold running water for at least ten minutes.

The best way to treat bleeding is to put the wound under a tap. If you put a bleeding wound under a tap you wash away the body's clotting agents(凝血剂) and make it bleed more. Instead put pressure on the wound with whatever is available to stop or slow down the flow of blood. As soon as possible call 999. Keep pressure on the wound until help arrives.

Nosebleeds are best treated by putting the head back. If you put the head back during a nosebleed, all the blood goes down the back of the airway. Instead advise them to tilt(倾斜) their head forwards and ask the person to pinch(捏) the end of their nose and breathe through their mouth.

You need lots of training to do first aid. You don’t - what you mostly need is common sense. You can learn enough first aid in a few minutes to save someone's life – whether it’s from a book, attending a course or watching videos online.
