Have you ever tried making music with glasses or bottles filled with water? I bet your favorite band hasn’t. Experiment with your own special sounds by turning glasses of water into instruments, make some cool music and find out how it works.
What you’ll need:
Five or more drinking glasses or glass bottles. Water. Wooden stick such as a pencil. If possible, you’d better do it in a small but empty room with a long table in.
Instructions:
Line the glasses up next to each other and fill them with different amounts of water. The first should have just a little water while the last should be almost full, and the ones in between should have slightly more than the first.
Hit the glass with the least amount of water and watch the sound, then hit the glass with the most water, which makes the higher sound?
Hit the other glasses and see what noise they make. See if you can get a tune going by hitting the glasses in a certain order.
What’s happening?
Each of the glasses will have a different tone when you hit with the pencil. The glass with the most water will have the lowest tone while the glass with the least water will have the highest. Small vibrations (震动) are made when you hit the glass, and this creates sound waves which travel through the water. More water means slower vibrations and a deeper tone.
1.What’s needed in the experiment according to the passage?
A. Five bottles of water. B. Seven drinking glasses
C. A big and empty room. D. A pencil and a wooden stick.
2.According to the passage , the purpose of the experiment is to get __________.
A. a tone. B. a tune. C. some vibrations. D. some water
3.Which glass can have the lowest tone when you hit it in the experiment?
A. The one with no water. B. The one with the most water.
C. The one with the least water. D. The one with half of the water.
4.Where is the passage the most likely to come from?
A. A Travelling Guide B. A Child Novel
C. A Fashion Magazine D. A Music Textbook.

When you watch 3D movies or TV,you have to wear a special pair of glasses.The 3D glasses make the images from the screen look like they are there in the room with you.
Three-dimensional,or 3D,means having three dimensions(维度) : width,height and depth.3D technology(技术) is based on the way the human brain(大脑) and eyes work.Because the pupils of a person's eyes are about 6.5era apart(分开),when we look at something,each eye sees it from a different angle(角度).Our eyes send the two images to our brain,and the brain puts them together.The small difference between the image from the right eye and the image from the left eye allows us to see depth.
When we view pictures and television in two dimensions,each eye gets the same information.That is because the image has no real depth,and there is only one of viewing it.So the goal of 3D technology is to get a different image into each of the viewer.It uses two film projectors.One projects a left eye image and the other projects a right image.The 3D glasses allow us to see a different image in each eye.
While watching 3D films,we feel that we are in the same environment as the things we're watching.However,it also has its disadvantages.The 3D glasses work by controlling the amount of light that reaches the eyes.It makes the screen look darker.What's more,people with eye problems may get headaches if they spend too much time watching 3D movies,because their brains need to work harder to "read" the images.
1.According to the passage,we can see 3D TV with the help of ____.
A.the exciting games B.the special glasses
C.the dark screen D.the image in the room
2.The second paragraph mainly tells us ____.
A.how we see things in 3D
B.how 3D films are made
C.what the human brain does for our eyes
D.how different images get into the brain
3.The underlined word "pupils" in the passage means____ in Chinese.
A.学生 B.视线 C.睫毛 D.瞳孔
4.Which of the following is TRUE?
A.3D glasses make the screen look brighter.
B.People with eye problems can't see 3D films.
C.A 3D film needs making by two film projectors.
D.3D glasses held people get the same image in each eye.

Creator of e-mail makes use of ‘@’ sign
Does your class use e-mail? Have you ever tried to write a story for our newspaper and send it in by e-mail? E-mail is used for everything, and it makes life easier. But do you know where e-mail came from?
The man who invented it was Ray Tomlinson, a US engineer. He died early last month at the age of 74.
Back in 1971, Tomlinson was working on something that could send messages from one computer to another. Tomlinson tried to find a way to separate users’ name from the names of their computers. He needed some kind of symbol (符号). However, it couldn’t be a popular one, and it couldn’t be one that computers might know in a different context (语境). It also needed to be on keyboard at the same time. The “@” sign was there, and pretty much no one used it. It was perfect.
“The ‘@’ sign made the most sense,” he told Wired in 2012. “It said where the user was…at.” For example, by writing “Alex at 21st Century Teens” you can send a message to somebody named Alex who works at 21st Century Teens. This was the early form of email.
The interesting thing is that Tomlinson didn’t remember what the very first test message he sent was. “Probably the first message was QWERTYUIOP or something like that,” Yahoo reported, guessing the first row of letters on the keyboard.
Tomlinson, the father of e-mail, changed the way the world communicates and more importantly saved the symbol “@”.
Today, the “@” symbol is finding new life outside of our inboxes (收件箱). Most famously, social media like Weibo and Wechat use it at the beginning of user names. So even if we don’t use e-mail some day, Tomlinson’s contribution (贡献) will certainly live on.
1.Who invented the e-mail?
_____________________________________________________________________
2.When did he invent the e-mail?
_____________________________________________________________________
3.Why did he choose the symbol “@”?
_____________________________________________________________________
4.What does “@” sign tell us?
_____________________________________________________________________
5.What’s the passage mainly about?

Have you ever wished to have an umbrella that makes your hands free? Alan Kaufman has come up with the “Nubrella”, which means “new” + “umbrella”. It is the first truly hands-free umbrella in the world. The inventor says that it stops rain, wind and snow and can keep your head, face and hair dry.
“I never planned to invent a product. I just noticed a problem and had a new idea,” said the inventor. The idea for the invention began on one rainy day. Mr Kaufman was standing in one of his stores. He began to look at people’s umbrellas. He found that they had to try very hard to keep their umbrellas in the right place. At that moment an idea came into his mind. He ran to his desk and drew a picture. In this way, the nubrella was born.
One cool feature of the nubrella is that you don’t hold it like a normal umbrella; you wear it. The shoulder straps (肩带) of the nubrella allow people to be fully hands-free, so when walking in the rain with the nubrella, you are able to use your cell phone or drink a hot cup of coffee. Also, the nubrella will never be inverted (颠倒) in the wind. The new umbrella is far safer than traditional ones, because it has no sharp points.
1. “Nubrella” is a kind of _____ umbrella.
A. normal B. hands-free
C. traditional D. paper
2. --- How can you use the “Nubrella”?
--- You can _____.
A. wear the shoulder straps of the nubrella
B. put the nubrella on your head
C. use your hands to hold it up
D. carry it on your bike
3.Which of the following is not right?
A."Nubrella" means "new" + "umbrella".
B.The idea of the nubrella came from the rainy day.
C.Walking in the rain, you'd better take the nubrella.
D.If you go out with the nubrella, you have it in your hands.
