A mobile phone, also known as a cell phone, is one that we can use to make telephone calls to anyone from a great distance via a radio link. Apart from telephony, modern smart mobile phones also support a number of other services including text messaging, internet access, gaming, photography, and many business applications. The first cell phone weighed about 2 kilograms and was demonstarted in 1973 by Dr. Martin Cooper and John F. Mitchell of Motorola. Ten years later, in 1983, the first model of cell phone went on sale to the public. By 2011, over six billion people, 87% of the world's population, used mobile networks. In spite of the many advantages a cell phone has, it also brings about several problems that users should be awave of. Mobile phone radiation is believed to be harmful to human health. Some recent studies have found an association between cell phone use and certain kinds of brain disease. Another serious problem can be privacy and tracking. Once users have the phone on, they can be interrupted in many ways, and they can also be tracked by location data.

B. Texting is a new way of exchanging information, and it is becoming more and more popular among the young. In fact, texting is clearly affecting on the language. There are no rules for it. We are creating a new aspect of vocabulary and opening up a new kind of playful and that's fine, but some people are worried about the affects it might have on child' ability to read and write. But not everyone is so worried. An expert says, "Every time a new medium comes along, it has an effect on language... but this doesn't destroy the existing language, it adds to it". In text massages, words may come from shorthand created in email such as CUS (See you soon) and so on. Someone says, "Mostly they are original, but sometimes you get a class os meanings. For example, LOL can mean both Laugh Out Loud and Lots of Love. That could lead to some misunderstanding."

Telephones help people speak to one another when they are apart. For more than a hundred years, nearly every telephone was a landline. A landline telephone is one that needs to be connected by a wire to a network of other telephones. Because of the wires, people could not take those telephones with them when they left their homes or offices.

What if you had to make a call while you were away from home? You had to find a pay phone. Pay phones are landlines found in public places. Many pay phones are on the street. You can make a call from inside a glass or metal space called a phone booth. Once you are inside the booth, you put coins into a slot in the phone to make a call.

Telephones have seen a lot of progress. Today, many people carry cell phones. Cell phones do not need to be connected with wires. They can be used almost anywhere and can fit in an adult’s hand.

Many cell phones sold today are smart phones. A smart phone is a cell phone that has lots of computer-style features. For example, people use smart phones to check e-mail and go on the Internet. And all that can be done using something small enough to carry in a pocket!

Question: What is the difference between smart phone and cellphone?

A. It weighs heavier

B. It weighs heavier

C. It has more features

D. It needs restoring

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42

Since the dawn of time, people have found ways to communicate with one another. Smoke signals and tribal drums were some of the earliest forms of communication. Letters, carried by birds or by humans on foot or on horseback, made it possible for people to communicate larger amounts of information between two places. The telegram and telephone set the stage for more modern means of communication. With the invention of the cellular phone, communication itself has become mobile.

For you, a cell phone is probably just a device that you and your friends use to keep in touch with family and friends, take pictures, play games, or send text message. The definition of a cell phone is more specific: it is a hand- held wireless communication device that sends and receives signals by way of small special areas called cells.

Walkie - talkies, telephones and cell phones are duplex communication devices: They make it possible for two people to talk to each other. Cell phones and walkie- talkies are different from regular phones because they can be used in many different locations. A walkie- talkie is sometimes called a half- duplex communication device because only one person can talk at a time. A cell phone is a full- duplex device because it uses both frequencies at the same time. A walkie-talkie has only one channel. A cell phone has more than a thousand channels. A walkie- talkie can transmit and receive signals across a distance of about a mile. A cell phone can transmit and receive signals over hundreds of miles. In 1973, an electronic company called Motorola hired Martin Cooper to work on wireless communication. Motorola and Bell Laboratories (now AT& T) were in a race to invent the first portable communication device. Martin Cooper won the race and became the inventor of the cell phone. On April 3, 1973, Cooper made the first cell phone call to his opponent at AT& T while walking down the streets of New York city. People on the sidewalks gazed at cooper in amazement. Cooper's phone was called A Motorola Dyna- Tac. It weighed a whopping 2.5 pounds (as compared to today's cell phones that weigh as little as 3 or 4 ounces)

After the invention of his cell phone, Cooper began thinking of ways to make the cell phone available to the general public. After a decade, Motorola introduced the first cell phone for commercial use. The early cell phone and its service were both expensive. The cell phone itself cost about $ 3, 500. In 1977, AT & T constructed a cell phone system and tried it out in Chicago with over 2, 000 customers. In 1981, a second cellular phone system was started in the Washington,D.C and Baltimore area. It took nearly 37 years for cell phones to become available for general public use. Today, there are more than sixty million cell phone customers with cell phones producing over thirty billion dollars per years

What definition is true of a cell phone?

A. The first product of two famous corporation.

B. A hand-held wireless communication device

C. Something we use just for playing games.

D. A version of walkie- talkie
