问题 单项选择题

体育运动导致身体出汗而流失诸如钠、钾等电解质。为了恢复体液中的电解质平衡,请你在比赛间隙喝我们富含钠、钾的特制运动饮料。
如果下面哪一项为真,上文中的广告所描述的原理就具有潜在的误导性

A.通过在比赛间隙喝大量饮料来给身体迅速降温会导致运动员的注意力不够集中。
B.在运动期间,由于身体流失的水分远多于电解质,体内电解质的浓度将上升。
C.如许多软饮料那样,从所含物质的重量来讲,广告中的特制运动饮料所含有的糖分要远高于其中的由钠或钾等元素组成的物质成分。
D.为了让肌肉组织发挥最好的功能,保持体液中适量浓度的电解质是很必要的。
E.一些运动员选择等到比赛结束后再来想办法使自己体液中的电解质恢复平衡。

答案

参考答案:B

解析:广告的观点是运动比赛间隙喝富含钠、钾的饮料,以恢复体液中的电解质平衡。B选项的信息是“身体流失的水分远多于电解质,体内电解质的浓度将上升”,这就意味着更需要补充的是水分而不是电解质。他因削弱。

It seems some people have something bad to say about Facebook, the social media website that now has attracted more than 300 million members. To them I have only this to say: Stop please!

A recent article in the Wall Street Journal blamed Facebook’s ability to ruin friendships, saying that it limits communication to typing and encourages people to spend far too much time with friends they have never met.

Having used Facebook since its first year, I find these arguments false. The simple truth is that the problems are only a symptom of Facebook abuse. Like many things, it is only as harmful to your life and relationships as you allow it to be. Consider arguments against watching too much TV and overeating.

Try using Facebook to find friends who may have long ago changed their e-mail addresses and phone numbers, to find out what your old college friends are up to, to congratulate your friends on their latest birthdays, to share pictures and articles you find interesting, and to join in the discussion about them with your friends.

Sure, I had days when I wasted a little more time on Facebook than I should, but I’m not going to blame Facebook for my own laziness. If Facebook wasn’t there, I would have found something else to waste time on. To my “friends”: if you don’t feel like broadcasting your life stories on your Facebook, don’t. If you tire of my personal updates, ignore them. If you don’t want to join in the popular online games, don’t. It is a fun tool at your fingers that can be used for both good and bad. If you don’t like using Facebook, don’t.

I am now a consultant at the Department of State. I use Facebook to keep in touch with friends, family, and colleagues who live and work all over the world.
