A recent survey of crime statistics shows that we are all more likely to be burgled now than 20 years ago and the police advise everyone to take a few simple precautions to protect their homes.

The first fact is that burglars and other intruders prefer easy opportunities, like a house which is very obviously empty. This is much less of a challenge than an occupied house, and one which is well-protected. A burglar will wonder if it is worth the bother.

There are some general tips on how to avoid your home becoming another crime statistic. Avoid leaving signs that your house is empty. When you have to go out, leave at least one light on as well as a radio or television, and do not leave any curtains wide open. The sight of your latest music centre or computer is enough to tempt any burglar.

Never leave a spare key in a convenient hiding place. The first place a burglar will look is under the doormat or in a flower pot and even somewhere more 'imaginative' could soon be uncovered by the intruder. It is much safer to leave a key with a neighbor you can trust. But if your house is in a quiet, desolate area be aware that this will be a burglar's dream, so deter any potential criminal from approaching your house by fitting security lights to the outside of your house.

But what could happen if, in spite of the aforementioned precautions, a burglar or intruder has decided to target your home? Windows are usually the first point of entry for many intruders. Downstairs windows provide easy access while upstairs windows can be reached with a ladder or by climbing up the drainpipe. Before going to bed you should double-check that all windows and shutters are locked. No matter how small your windows may be, it is surprising what a narrow gap a determined burglar can manage to get through. For extra security, fit window locks to the inside of the window.

What about entry via doors? Your back door and patio doors, which are easily forced open, should have top quality security locks fitted. Even though this is expensive it will be money well spent. Install a burglar alarm if you can afford it as another line of defence against intruders.

A sobering fact is that not all intruders have to break and enter into a property. Why go to the trouble of breaking in if you can just knock and be invited in? Beware of bogus officials or workmen and, particularly if you are elderly, fit a chain and an eye hole so you can scrutinize callers at your leisure. When you do have callers never let anybody into your home unless you are absolutely sure they are genuine. Ask to see an identity card, for example.

If you are in the frightening position of waking in the middle of the night and think you can hear an intruder, then on no account should you approach the intruder. Far better to telephone the police and wait for help.

According to the writer, we should _______.

The “aforementioned precautions” refer to steps that _______.

According to the writer, window locks, security locks and burglar alarms _______.

The writer argues that fitting a chain and an eye hole _______.

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.

In 1826, a Frenchman named Niépce needed pictures for his business. He was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.

The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything clearly, even the smallest details. This kind of photograph was called a daguerreotype.

Soon, other people began to use Daguerre's process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities, and mountains.

In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple and photographers had to carry lots of film and processing equipment. However, this did not stop photographers, especially in the United States. After 1840, daguerreotype artists were popular in most cities.

Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were lifelike and full of personality. Brady was also the first person to take pictures of a war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.

In the 1880s, new inventions began to change photography. Photographers could buy film ready-made in rolls, instead of having to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive.

With a small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends, and favorite places. They called these pictures "snapshots".

Documentary photographs became popular in newspapers in the 1890s. Soon magazines and books also used them. These pictures showed true events and people. They were much more real than drawings.

Some people began to think of photography as a form of art. They thought that photography could do more than show the real world. It could also show ideas and feelings, like other art forms.

Daguerre took a picture of his studio with ______.

The word “this” in the passage refers to the ______.

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.

The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. People of different cultures are more prone to contact certain illnesses because of the characteristic foods they consume.That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates nitrites (commonly used to preserve color in meat) as well as other food additives caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which ingredients on the packaging label of processed food are helpful or harmful. The additives that we eat are not all so direct. Farmers often give penicillin to cattle and poultry, and because of this, penicillin has been found in the milk of treated cows.Sometimes similar drugs are administered to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.A healthy diet is directly related to good health. Often we are unaware of detrimental substances we ingest. Sometimes well-meaning farmers or others who do not realize the consequences add these substances to food without our knowledge.

Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds, while during the fifteenth century the term “reading” undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace.

One should be wary, however, of assuming that silent reading came about simply because reading aloud was a distraction to others. Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode of reading for most adults mainly because the tasks themselves changed in character.

The last century saw a steady gradual increase in literacy and thus in the number of readers. As the number of readers increased, the number of potential listeners declined and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.Towards the end of the century, there was still considerable argument over whether books should be used for information or treated respectfully and over whether the reading of materials such as newspapers was in some way mentally weakening. Indeed, this argument remains with us still in education. However, whateverits virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialised readership on the other.

By the end of the twentieth century, students were being recommended to adopt attitudes to books and to use reading skills which were inappropriate, if not impossible, for the oral reader. The social, cultural and technological changes in the century had greatly altered what the term “reading” implied.

The word “commonplace” in the first paragraph mostly means “______”.

The development of silent reading during the last century indicated ______.

Silent reading, especially in public places, flourished mainly because of ______.

The phrase “a specialized readership” in paragraph 4 mostly means “______”.

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

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 is the main idea of the passage?

What definition is true of a cell phone?

What is wrong about a walkie- talkie?

The word "duplex" is closest meaning to ________.

To whom did Cooper make his first cell phone call?

How heavy is the first cell phone compared to today's cell phones?

When did AT& T widely start their cellular phone system?

What does the word" gazed" mean?

The phrase " tried it out" refers to __________ .
