Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air. Then, the sunlight will no longer be blackened out by smoke and soot.There are many ways to fight pollution in the present word. One way is to reduce the amount of cars being produced. This would lead to less smog and decrease pollution. Another way is to plant more trees. This would increase the oxygen in the air and lead to a heathier environment. Three other ways to fight pollution: Disposing of trash properly, decreasing the use of pesticides, and always recycling water bottles.It is now a fact, air pollution effects and causes millions of deaths. Outdoor air pollution effects and causes an estimated 800,000 deaths each year. Indoor air pollution effects and causesan additional 1.6 million premature deaths. Air pollution is the single greatest environmental threat to human health关于记忆Most people, unless they have a photographic memory, have problems with short term memory to some degree. I have a very difficult time remembering names, and even items that I need at the grocery store. If you are like me and can't remember where you placed your keys, don't fret-help is on the way! The first thing you should do is to stop reinforcing your belief that you have a bad memory, because the more you believe this about yourself, the worse your memory will get. Now begin to stimulate your brain with new information every day.You may have problems remembering because you don't challenge your brain with new material or fun activities. When you are learning something new, like a new language, your brain starts building new pathways of nerve networks, so you can retrieve information when you need it. You can exercise your brain by playing games similar to the concentration game.I love playing a game of Concentration at this website: /games/concentration.html.I have it bookmarked so I can go to it whenever I want. There are versions of Concentration online that you can download and play. The more you practice playing the game the quicker you can solve the puzzle.Defined in broad terms, a mnemonic is a device, procedure, or operation that is used to improve memory. Defined in narrow terms — and what Scruggs and Mastropieri mean by the word — a mnemonic is a specific reconstruction of target content intended to tie new information more closely to the learner's existing knowledge base and, therefore, facilitate retrieval. There are a variety of mnemonic techniques, including keywords, pegwords, acronyms, loci methods, spelling mnemonics, phonetic mnemonics, number-sound mnemonics, and Japanese “Yodai” methods. An example of an acronym is to remember the word HOMES to recall the names of the Great Lakes: Huron, Ontario, Michigan, Erie, and Superior.Scruggs and Mastropieri demonstrate, first of all, that memory can be trained, and second, the importance of memory training in helping LD children. There are, however, at least two problems in improving memory by means of mnemonic instruction. The first problem is that it overlooks the sequential fashion of learning. Mnemonics instruction is, to a large extent, instruction in memory techniques, which should be taught only after the skill of memory has been learned. It can be compared to a child being taught soccer tactics, such as the “wall pass,” while he has not yet adequately mastered the skill of passing the ball. As stated in Knowabout Soccer, “No matter how good your passing technique, if thequality of your passing is poor, your technique will not be effective.” The second problem is that by teaching the child to use memory crutches, the result is, as Scruggs and Mastropieri acknowledge, “On more complex applications, generalization attempts have been less successful.” If the skill of memory is taught, however, the child can apply it in any situation.Audiblox teaches —among other skills —the skill of memory, which makes it possible for a person to apply his memory in any situation. The Audiblox Flashing exercises improve sensory register, while a variety of other Audiblox exercises aim at improving short-term and long-term memory, both auditory and visual.Have you ever experienced the tip-of-the-tongue phenomenon while taking exams, in which forgotten information feels like it’s just out of reach? Or have you ever grumbled how bad your memory is? Actually, most of us have a good memory, but we do not use it effectively. Some approaches with which we can use are definitely helpful to improve our memory based on some common characteristic of human memory.Memory is the retention of information over time. Although the word memory may conjure up an image of a singular, “all-or-none” process, it is clear that there are actually many kinds of memory, each of which may be somewhat independent of the others. One way to describe memory is by reference to the form it takes, that is, the different ways memory may be assessed: recall, recognition, and paired associates.The most popularly studied kind of memory is recall. Recollection of a telephone number you have just heard, a list of items you are to purchase at the store, or a list of dates you learned in history class are all examples of recall.A second type of memory is recognition, which is generally easier than recall, for example a history teacher gives four dates and learners are to choose the one that goes with the specific historical event.Another kind of memory is called paired associates. It is a child’s ability to memorize a list of paired items, such as pictures and names, common objects and nonsense syllables, or words and corresponding visual scenes.Improving MemoryFor centuries it was believed that memory can be improved. The Greeks, and later the Romans, developed some of the most prodigious memories the civilized world has ever seen. Memory was ranked as one of the most important disciplines of oratory, a flourishing art at the time. They lived in an age with no paper, so p eople couldn’t readily refer to notes. Speeches were committed to memory; lawyers depended on their memory in court; and poets, whose roles in society was paramount, regularly drew on their enormous powers of recall to recite long passages of verse.。
