Wi-Fi is a wireless networking technology used across the globe. A 1 misunderstanding is that the term Wi-Fi is short for “wireless fidelity(保真度)”. However, this is not the case. Wi-Fi is 2 a trademarked phrase that uses the 802.11 standard, which was 3 by the Institute of Electrical and Electronics Engineers (IEEE). That is to say, instead of using 4, your computer is connected to the internet or other computers by radio.
This standard was 5 promoted by the Wi-Fi Alliance, a trade group that pioneered commercialization of the 6. A person or business can use a wireless router( 路由器) or a similar 7 to create a “hotspot” or an area in which proper devices can connect wirelessly to a network or 8 Internet access. This router is usually connected to the Internet by 9 of a modem, often one 10 as a high-speed connection. Any user within about 200 feet of the 11 point can then connect to the Internet, 12 for good transfer rates, distances of 100 feet or less are often suggested. Salespersons also sell signal boosters（放大器）that 13 the range of a wireless network.
Wi-Fi networks can either be 14 or closed, in which case a 15 is needed. An area blanketed in wireless access through a device is often called a “wireless 16.” Anyone with a device that 17 proper functionality can connect to this network while in the hotspot. Through this connection, a 18 network can be accessed or Internet connectivity can be achieved. This allows people within the hotspot to connect to the Internet via the router and modem, often 19 for employees at a business or as a free 20 at coffee shops and similar locations.

Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.
Maybe that doesn't sound very interesting. But when you've joined to the Internet, there are lots of things you can do. You can send e-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW).
There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people's desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.
There are lots of places for you to go into the Internet. For example, your school may have the Internet, you can use it during lessons or free time. Libraries often have computers joined to the Internet, you are welcome to use it at any time.
Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?

You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how:
Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First set your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying . A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.
Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.
Make good use of your time in class. Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.
Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day and read that material. If you do these things regularly, the material will become more meaningful, and you'll remember it longer.
Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so don't be over worried.
. You will probably discover many others after you have tried these.

This morning on my way to school I was deep moved by what I saw outside a bank. An old man was counting his money in the front of the bank. Suddenly a young man came running and knocked him down. To make things bad, his money was lying in all direction. In no time the people around rush to pick the money up while the old man stood there, not know what to do. Surprisingly, everyone gave back the money they had just picked. The old man counted the money again and found that not a single bill was missed. To my great joy, there are now a lot of nice people in your life. It's true what honesty is more important than money!
