In a world where technology is king, it is getting more and more difficult to keep up with the ‘R’s— VR. AR, MR, (iPhone) XR and the list goes on.
Many people have trouble telling the differences between augmented reality (AR) and virtual reality (VR) . AR and VR mean that we experience something that isn’t there, but it feels like it is. As a result, it is easy for users to be blown away and wonder what is real and what is not. In short, at the heart of AR and VR are two very similar technologies. Both offer experiences to users, most widely used in areas such as online shopping and as part of psychological treatments.
_______ The main difference lies in the way of transport. Simply put, VR ‘transports’ the user to another world instead of the real one. It uses computer technology to create a 3D environment. Users not only view a screen in front of them, but also use as many senses as possible, such as vision, hearing, touch, even smell. VR is used widely in many theme parks, like Disneyland. Imagine opening your eyes and seeing a new world created by the computer all around you; you can move in this environment and even communicate with it. That’s what VR is like. For example, VR has the power to make users feel as if they are falling. So sometimes while playing games, users become nervous and even scared.
AR, does not shut out the real world, but adds digital graphics to a live view often by using the camera on a smartphone. Users would not be ‘transported’ to another world but instead, they would see graphics created by computers with what they see in real life. AR makes it possible to create many interesting apps, such as the navigation. It does not, change the whole view of what users see. unlike VR.
Thanks to new technology and successful games, AR and VR users already have a lot of choices. AR and VR are both powerful technologies which are still relatively new to many users. However, they have already begun to shake things up in the gaming world. The worlds of AR and VR aren’t just here: they’re getting bigger and better by the day.

Do you think that a snowshoe hare (雪鞋兔) wears snowshoes? Do you know what snow shoes are? Maybe you live in a warm place where it doesn’t snow. You would then never need to wear snowshoes.
But the lovely snowshoe hares are wearing “snowshoes”. They can be found in the forests in North America. They got their name because of the large size of their back legs. The legs stop them fromsinkinginto the snow when they jump and walk.
Snowshoe hares are not rabbits. Although hares and rabbits are in the same animal family, they are a bit different. Hares are a little larger than rabbits, and they usually have longer legs and bigger ears. Rabbits can’t see and have no fur (软毛) when they are born. They are able to see and get fur when they grow a little older. Hares, however, are born to see, fully furred and ready to run.
Snowshoe hares live in places where the winter is cold. Just like leaves of trees turning colour in autumn, snowshoe hares turn from brown to white during the winter, so they can be of the same colour as the snow and keep away from danger. They turn brown again in spring. It takes about ten weeks for them to fully change colour. The only part of the fur that doesn’t change colour is the very tops of the ears, which stay black.
Snowshoe hares are active at night. When the sun goes down, they come out for dinner. Grasses and berries are their favourite foods.

Do you use a calendar to help you organize your life? By listing what your need to do on any special day, you can make sure to keep all for your meeting and not worry whether you’ve forgotten something, Calendars are also useful for reminding (提醒) people what day a certain holiday is on and what days you might have off from work. Besides, they are used for planning fun things like vacations and outings.
A calendar is usually divided into twelve parts, and each one stands for a month with all the days laid out in a grid-like (网格状的) form. A block of space usually is for a day, and there is enough space for you to write down what you need to do that certain day. You probably use all different kinds of calendars. A calendar on your cell phone screen is easy to use, and so is a large paper calendar that hangs on your wall.

In every school there is “top” crowd that sets the pace, while the others follow their lead. For example, if the crowd decides that it is smart to wear bright red sweaters, then very soon everybody is wearing bright red sweaters.
There is nothing wrong with that, except the fact that for some people bright red sweater is really unsuitable.
The situation can even become dangerous, if the top crowd decides that it is smart to drink and to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the slaughter(屠杀).
Now it’s possible that you have come across situations like these more than once in your life. In fact you probably did something you knew to be wrong one time or another. You may have excused yourself by saying, “ Gee, the crowd does it.” Well, let the crowd do it, but don’t do it yourself. Learn to say “No”.
Develop your own standards(标准)and your own judgment. If you know the crowd is planning something you disagree to, you’d better take the courage to bow out in a polite way. You’ll have the satisfaction of standing on your own two feet.
