April will bring a new product– the Apple Watch into the market. Last week, the watch was firstly introduced by Tim Cook, Apple's CEO. The price of the watch is from $349 to $1,099, depending on its size and whether it is a sports or regular one. Apple engineers and designers have put in a lot of thought and hard work into creating this small screen on your wrist. The sensor(传感器)on the screen not only finds your finger, but also knows the difference between when you are tapping(轻触), and when you are pressing harder.

The watch also has haptic feedback(触觉反馈). You can send personal messages to your friend —such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist.

Besides telling the time, the watch will use 'Bluetooth' to connect with your iPhone and show calls or text messages that come in.

According to Tim Cook, the watch may open up a whole new area of applications（应用） that we had never thought of. Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch. A 'Hotels' app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even at the airport—passengers may be able to simply wave their wrist to check into their flight.

The biggest use of the watch, however, is as your personal fitness coach. The watch can show your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same sensor as your iPhone, so it knows when you are moving, and also how much you are walking or running. It will remind you if you have been sitting for too long without taking exercise.

A、is designed by Tim Cook B、was brought into the market last week C、sells at different prices for different colors D、will come into the market this coming April..

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can only buy telephone cards, and some cards cost up to ￡4,000.The first Japanese card has a value of about ￡28,000. Most people only see cards with prices like these in their collectors' magazine.

The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind. The sea is very big. It covers three quarters of the earth. The sea is also very deep in some places. In one place, the sea is about 11 kilometres deep. The highest mountain(山) in the world is about nine kilornetres high. If that mountain was put into the sea at that place, there would still be two kilometres of water above it!
In most parts of the sea,there are plenty of fishes and plants (植物). Some live near the top of the sea.Others live deep down. There are also a lot of small living things,and lots of fish live by eating them. The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But,in 1970,five women scientists lived in the deep sea for fourteen days.

Have you ever had dreams about building a robot? Or putting together a spaceship? Or even seeing your face made out of chocolate? Done. All you need is a 3-D printer.

The possibilities of 3-D printing seem endless(无穷尽的）.All the user has to do is to design an object on the computer and choose a material to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses(按）“print", the 3-D printer spreads the materials layer(层）by layer and like magic the object is produced.

The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.

But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous.

In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers(提款机盗刷器).These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.

But for better or for worse, 3-D printing has been put into use. In a few years, you'll probably be wondering how you could ever live without your 3-D printer!

When throwing away rubbish, do you know which Bin it should go in? Have you ever noticed the differently-colored Bins on the street?

Some of you might not be able to answer this question. However, it's actually quite important to know how to sort your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.

If you don't sort your waste, all of it will go to a landfill and Be Buried(埋) together. These landfills can take up large areas of ground that could have Been used for planting trees or Crops. The electronic waste you throw away, such as Batteries, Can pollute the soil and groundwater. Other pieces of waste, like the metal part of a pen, can be used to make other things if they are properly recycled.

With this in mind, many Cities in China have Been running waste-sorting Campaigns (活动)in recent years. For example, Shanghai announced in July that within three years, all of its residents(居民)should sort their waste into four groups wet, recyclable, harmful and dry.

"Wet" waste is also known as household waste." They are things you don't want but that pigs can eat," Guangzhou Daily explained. Paper, metal, glass and other things that Can Be reused are recyclable waste.

Harmful waste includes things like medicine, Batteries and fluorescent Bulbs. Finally, any waste that's not wet, recyclable or harmful will go in the" dry waste" bin.

Many other Chinese Cities, including Shenzhen, plan to use this method to sort their garbage. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their waste.
