Question

【題目】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（新陳代謝） 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.

試題分析：這篇文章主要介紹了一種具有咖啡的提神功效的快速提神制劑，又稱為“能量噴霧劑”。

【1】細節(jié)題。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.句意為這位化學家說，工作疲憊的人可以直接用它在皮膚上“來一發(fā)”咖啡因，無需受到咖啡機嗡嗡聲的折磨，不用擔心攝入過多卡路里，也不會在喝完咖啡或其他能量飲料后嘴里出現(xiàn)難聞的味道可以推斷出，故選B。

【2】大意概括題。由第五段中的The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陳代謝） 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.句意為之所以這樣說，是因為我們的產(chǎn)品無需口服，咖啡因在進入人體循環(huán)系統(tǒng)為你所用之前，不會參與肝臟負責的新陳代謝。能量噴霧網(wǎng)站還建議使用者把咖啡噴霧噴在普通香水的作用位置，比如脖子和手腕，但警告使用者一天噴霧不要超過20次以上可以推斷出，故選C。

【3】推斷題。由第五段中的but warns users not to exceed 20 sprays a day.句意為但警告使用者一天噴霧不要超過20次以上可以推斷出該產(chǎn)品不能大量使用，因此還沒有大量生產(chǎn)，故選B。

【4】推斷題。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.句意為網(wǎng)站聲稱，當噴霧作用于皮膚上時，使用者會感到“清醒專注而不會過度興奮”，正是咖啡和能量飲料通常具備的效果可以推斷出該噴霧具有咖啡等飲料的提神功效，且使用更方便，因此作者持支持態(tài)度，故選B。
