Question

【题目】D

Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee.

U.S. biochemist Ben Yu has created `Sprayable Energy,` which claims to be the world`s first caffeine - based topical energy spray.He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.

The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee.

Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe.The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure.Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup.

The website said: `The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陈代谢） by the liver before entering your system and becoming available to your body.`

`Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee.`c`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.

It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.

试题分析：这篇文章主要介绍了一种具有咖啡的提神功效的快速提神制剂，又称为“能量喷雾剂”。

【1】细节题。由第二段中的He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.句意为这位化学家说，工作疲惫的人可以直接用它在皮肤上“来一发”咖啡因，无需受到咖啡机嗡嗡声的折磨，不用担心摄入过多卡路里，也不会在喝完咖啡或其他能量饮料后嘴里出现难闻的味道可以推断出，故选B。

【2】大意概括题。由第五段中的The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陈代谢） by the liver before entering your system and becoming available to your body.website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.句意为之所以这样说，是因为我们的产品无需口服，咖啡因在进入人体循环系统为你所用之前，不会参与肝脏负责的新陈代谢。能量喷雾网站还建议使用者把咖啡喷雾喷在普通香水的作用位置，比如脖子和手腕，但警告使用者一天喷雾不要超过20次以上可以推断出，故选C。

【3】推断题。由第五段中的but warns users not to exceed 20 sprays a day.句意为但警告使用者一天喷雾不要超过20次以上可以推断出该产品不能大量使用，因此还没有大量生产，故选B。

【4】推断题。由最后一段中It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.句意为网站声称，当喷雾作用于皮肤上时，使用者会感到“清醒专注而不会过度兴奋”，正是咖啡和能量饮料通常具备的效果可以推断出该喷雾具有咖啡等饮料的提神功效，且使用更方便，因此作者持支持态度，故选B。
