In the history of technology, computers and calculators were innovative developments. They are essentially different from all other machines because they have a memory. This memory stores instructions and information. In a calculator, the instructions are the various functions of arithmetic, which are permanently remembered by the machine and cannot be altered or added to. The information consists of the numbers keyed in.
An electronic pocket calculator can perform almost instant arithmetic. A calculator requires an input unit to feed in numbers, a processing unit to make the calculation, a memory unit, and an output unit to display the result. The calculator is powered by a small battery or by a panel of solar cells. Inside is a microchip that contains the memory and processing units and also controls the input unit, which is the keyboard, and the output unit, which is the display.
The input unit has keys for numbers and operations. Beneath the key is a printed circuit board containing a set of contacts for each key. Pressing a key closes the contacts and sends a signal along a pair of lines in the circuit board to the processing unit, in which the binary code for that key is stored in the memory. The processing unit also sends the code to the display. Each key is connected by a different pair of lines to the processing unit, which repeatedly checks the lines to find out when a pair is linked by a key.
The memory unit stores the arithmetic instructions for the processing unit and holds the temporary results that occur during calculation. Storage cells in the memory unit hold the binary codes for the keys that have been pressed. The number codes, together with the operation code for the plus key,   are    held    in    temporary    cells    until    the    processing    unit    requires    them. When the equals key is pressed, it sends a signal to the processing unit. This takes the operation code-for example, addition-and the two numbers being held in the memory unit and performs the operation on the two numbers. A full adder does the addition, and the result goes to the decoder in the calculator's microchip. This code is then sent to the liquid crystal display unit, which shows the result, or output, of the calculation.

According to the passage, one function of the memory unit is     .

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a travelling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

The man mentioned in the passage, who used his cell phone too often, ________.

"There are many stereotypes about the character of people in various parts of the United States. In the Northeast and Midwest, people are said to be closed and private. In the South and West, however, they are often thought of as being more open and hospitable. Ask someone from St. Louis where the nearest sandwich shop is, and he or she will politely give you directions. A New Yorker might eye you at first and after deciding it is safe to talk to you, might give you a rather unexpected explanation. A person from Georgia might be very kind about directing you and even suggest some different places to eat. A Texan just might take you to the place and treat you to lunch.
 American stereotypes are known for their hospitality and warmth. New Englanders are often thought of as being friendly and helpful. Southerners are known for their hospitality and warmth. People from the western part of the United States are often considered very outgoing. These differences in character can be traced to different factors such as climate, living conditions, and historical development.
 When travelling from place to place, Americans themselves are often surprised at the different degrees of friendliness in the United States."

Insects’ lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look "inedible" by resembling or imitating plants is a deception widely practiced by insects. Mammals rarely use this type of camouflage, but many fish and invertebrates do.
The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.
Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection; they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.
Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the foliage that they resemble.

"Memorize these words". "Learn this spelling rule". "Don't forget about the quiz tomorrow".
You remember things every day, but how do you do it?
When you want to call a store or an office that you don't call often, you look in the telephone book for the number. You dial the number, and then you forget it! You use your short-term memory to remember the number. Your short-term memory lasts about 30 seconds, or half a minute. However, you don't need to look in the telephone book for your best friend’s number because you already know it. This information is in your long-term memory. Your long-term memory has everything that you remember through the years.
Why do you forget things sometimes? Is there a reason? Yes, there are several. The major reason for forgetting something is that you did not learn it well in the beginning. For example, you meet some new people, and right away, you forget their names. You hear the names but you do not learn them, so you forget them.
You can help yourself remember better. Here are some ideas:
Move information from your short-term memory to your long-term memory. You can do this if you practice the new information. Say it to yourself out loud. Think about it.
After you learn something, study it again and again. Learn it more than you need to. This process is called overlearning. For example, when you learn new words, practice using them in sentences. Don't try to memorize words from a list only.
Make sure that you understand new information. It is very difficult to remember something that you don't understand. Ask questions when you learn something new to be certain that you understand.
Do not listen to music or watch TV when you study. You will remember better if you concentrate on one thing at a time.
Try to connect new information with something that you already know. For example, when you learn the name of a new kind of food, think of a similar kind of food that you already know.
Divide new information into several parts (about five or six). Learn one part at time and stop for few minutes. Don't sit down and try to learn a very large amount of new information all at once.
Try to make a picture in your mind. For example, if you hear or see a new word, make a picture of how it looks to you in your mind. This “mental” picture will help you remember that word the next time you see or hear it.
Think of word clues to help you remember information. One very helpful kind of word clue is an acronym. An acronym is a word formed from the first letter of a group of words. For example, many American schoolchildren learn the names of the Great Lakes in the North America by remembering the word homes. Homes is an acronym that comes from the names of the Great Lakes: Huron, Ontario, Michigan, Erie, Superior.
Relax when you study! Try to enjoy yourself. You are learning new things every minute. You will remember better if you are happy and relaxed.
