MEMORY

          "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: 

1. 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. 

2. 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. 

3. 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. 

4. Do not listen to music or watch TV when you study. You will remember better if you concentrate on one thing at a time. 

5. 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. 

6. 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. 

7. 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. 

8. 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. 

9. 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.

You move information from your short-term memory to your long-term memory when you______.

A. call a friend over and over again

B. practice it by saying it to yourself out loud

C. relax in front of the TV set

D. write it out on a piece of paper

VI.            Read the following passage and do the following exercises.

The three Rs: • Reduce: Use fewer products and create less waste; • Reuse: Find a new use for old products; • Recycle: Turn plastic waste into something new.

To make life convenient, many disposable products are made, such as plastic bags and containers. As a result, huge amounts of plastic are thrown away every day, creating a big environmental problem. To solve this problem, we recycle or reuse plastic waste. Here are some examples of amazing, creative ways of recycling and reusing plastic.

In Taiwan, there is a building called the EcoARK. Three hundred tons of plastic waste were made into 1.5 million bottle-shaped bricks to build it. The plastic bricks, despite their light weight, are designed to survive earthquakes and typhoons.

Another amazing example of recycled plastic is a bridge in Scotland. It’s the world’s longest plastic bridge. Fifty tons of plastic bottles and containers were used to make it. It is so strong that it can hold 44 tons of people and vehicles. In addition, it doesn’t rust or need regular painting.

There is also a sailboat named Plastiki. It was built from about 12,000 plastic bottles and weighs about 9 tons. It sailed all the way across the Pacific Ocean from San Francisco to Sydney! The purpose of the journey was to make people aware that millions of tons of plastic are floating in and polluting the ocean.

Next time, before you throw away something plastic, see if it can be recycled, or think of a creative way to reuse it. It doesn’t necessarily have to be a big creation like the examples above. There are many simple, useful things you can do. For example, you can punch little holes in the bottom of a plastic bottle and use it to water plants. Or you can cut a bottle in half and use it as a hand shovel. Why don’t you try to come up with some creative ideas of your own?
