题目内容

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.

Do you have a lot of friends? 1.When you are at school, I’m sure you are doing much more than just studying. School is also the place you learn to get along well with people. But this is not always easy. What can you do if you don’t like one of your classmates?

If you discover that you have problems getting along with your classmates or friends, the most important thing to learn is tolerance(宽容). 2.We can not change the way that other people do things, so it is important to learn to live happily with them.

Tolerance will make everyone get on better with each other. Getting to know each other may help you understand why they do things differently. Something different does not exactly mean that it is bad. Tolerance teaches us to keep a peaceful temper(脾气)and an open mind.

3. You would like to be treated kindly by your classmates. So it is important for you to treat them kindly, too. If you tolerate something, it does not mean that you have to like it. No one is asking you to change who you are or what you believe in. Tolerance just means that you should respect the differences in others and not try to make them change.

4. As we know, the world is very different, and practicing tolerance in your own school and city can help make a difference.

A.You need remember an old saying, “Treat others how you want to be treated.”

B.It is the ability to realize and respect(尊重) the differences in others.

C.It is important to practice tolerance, because it will make everyone’s life easier.

D.Are you getting on well with the people around you?

E.It’s important to know why we should tolerate others.
