查看习题详情和答案>>Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here is how.
1). Plan your time carefully. When you plan your week, you should make a list of things that you can have to do. After making the list, you should make a schedule of your time. First time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don’t forget to set aside enough time fro entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.
2). 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 from everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.
3). Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what your teachers say.
4). Study regularly. When you get home from school, go over your notes. Review the important points that your teachers mentioned in class. If you want to know what your teacher is going to discuss the next day, read the material in advance. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.
5). Develop a good attitude about 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 overly worried.
There are other methods that might help you with your studying. You will probably discover many others after you have tried these.

“Any time! Any where! Decades ago there was no such thing” – “Communication”.
Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry.
To be honest, the world’s first mobiles were not so attractive and the range of effectiveness wasn’t very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work.
There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that’s not all.
20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet.
“The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute.” Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you.
Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine.

A. a global-used mobile phone B. a global mobile phone industry

B. with a GSM mobile phone, you can make a phone call in most parts of the USA
C. there are only two cell phone systems in the whole world: GSM and CDMA
