Question

We can express thoughts and feelings and send sounds and pictures on our smart phones today. We also communicate by using programs like Skype and Face Time. We can't send tastes, smells or touch, of course. But scientists in Britain are trying to develop a way for smart phones to do just that.

Adrian David Cheok is a professor at City University in London. He wants people to experience communication using all of their senses. He said "In the real world, we can open up the glass, open the window. We can touch, we can taste, we can smell in the real world."

To give users a sense of taste, researchers designed two electrodes (电极）that are placed on the tongue. A chemical process creates different tastes through molecules (微粒)on the surface of the tongue. This chemical process sends electrical signals that convince the brain that a person is tasting something. They have already created sour, salty, sweet and bitter tastes.

"You put these two silver electrodes in your mouth, you put your tongue in between and then it stimulates electrically your tongue and you get a virtual taste perception in your brain."

A device(设备）called "Scentee" permits users to have the sense of smell. Scentee plugs into a smart phone and can spray tiny clouds of fragrances, including flowers, fruits and coffee. Professor Cheok says the person speaking can activate the device.

Scentee holds a container with about 100 different smells. The container must be replaced when all the scents（pleasant smells) run out.

D. The advantages of the smart phones with new functions.

Answer

1.D

2.B

3.B

【解析】我们可以用智能手机发送想法、感情和声音，但是却不能发送味道、气味和触觉。现在英国的科学家们正在研制这样的新型智能手机。

1.推理判断题。根据短文第一段中We can't send tastes, smells or touch, of course. But scientists in Britain are trying to develop a way for smart phones to do just that.可知，我们不能用智能手机发送味道、气味或触摸，但是英国的科学家们正在努力研制一种智能手机可以做到这个。由此可见，这篇短文介绍的是科学研究，故应选D。

2.细节理解题。根据短文第三段中To give users a sense of taste, researchers designed two electrodes (电极）that are placed on the tongue. A chemical process creates different tastes through molecules (微粒)on the surface of the tongue. This chemical process sends electrical signals that convince the brain that a person is tasting something可知，首先是在舌头上放两个电极；然后通过微粒在舌头的表面形成不同的味道，这种化学过程会发送电信号，让大脑相信一个人正在品尝东西。由此可知B选项是正确的。

3.推理判断题。根据短文的第一段We can't send tastes, smells or touch, of course. But scientists in Britain are trying to develop a way for smart phones to do just that.我们就知道了文章的大意，给我们讲述英国的科学家研制一种能发送味道、气味或触觉的智能手机。上面的短文中介绍了taste和smell，因此接下来应介绍的是touch。故选B。

点睛：这是一篇科普说明文，短文比较难以理解，但是中心比较突出，文章的中心容易找到，对于一些细节的问题，我们可以根据题目的要求去理解。例如第2小题，这个题目是排序题，这样的题，我们可以先找到第一个和最后一个，用排除法，选择答案。它的答案集中在第三段中，我们可以根据原文，对比选项，这样就能比较快地得出答案。
