問題詳情：
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 café. 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. Sprayable Energy`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.
12. What can we learn about Sprayable Energy from the passage ?_______.
A. A bottle of Sprayable Energy is cheaper than 40 cups of coffee. .
B. Sprayable Energy lets users not worry about taking in unnecessary calories..
C. Sprayable Energy can be used at least 20 sprays a day
D. The caffeine spray is a colorless liquid that is absorbed through the skin..
13. What does the fifth paragraph mainly tell us ?____
A. Sprayable Energy is taken by mouth...
B. Before Sprayable Energy is absorbed by body, the liver entirely metabolizes it
C. How Sprayable Energy acts on user’s body and how users use the product.
D. Sprayable Energy is convenient but expensive.
14. We can conclude from the passage that ____
yable Energy can not be permitted to be used by people now.
B. Sprayable Energy has not already gone into mass production
C. Each spritz of Sprayable Energy has the same effect as a full cup of coffee
D. Sprayable Energy is well received by flagging workers.
15. The writer’s attitude towards Sprayable Energy ______

【回答】
12．B
【解析】細節理解題。根據文章第二段的句子“He said tired workers can spray a ‘shot’ of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories”可知Sprayable Energy讓用戶不要擔心攝入沒有必要的卡路里。故選B。
13．C
【解析】主旨大意題。根據文章第五段的句子“Sprayable Energy`s website recommends that users apply the spray in places where they normally spritz perfume,”可知這段主要告訴我們咖啡噴霧劑是怎麼對人體起作用並且用戶是怎麼使用這個產品的。故選C。
14．B
【解析】推理判斷題。根據文章第三段的句子“The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin”（咖啡噴霧劑專利正在申請審批過程中）可知Sprayable Energy還沒有批量生產。故選B。
15．B
【解析】細節理解題。根據文章最後一段的句子“It claims that after spraying the product on the skin, users will feel ‘awake and focused without being over-stimulated’,”可知作者對於咖啡噴霧劑的態度是積極的。故選B。
【備註】很多人爲了提神每天喝大量咖啡。現在美國科學家新發明了一種咖啡噴霧劑，只要像噴香水一樣噴在脖子手腕上，你就能馬上清醒，活力十足！有了這個提神神器，再也不擔心工作學習時沒精神了。
