Categories memory method is an old classic, durability test of the classic years of harsh memories of France. She refers people to learn the material first, and after analysis of different categories of order, and then to memory learning. After sorting study materials, showing its regularity, seems orderly, rule learners can go to memory. Meanwhile, organizers of the learning materials stored in the brain as being installed in a different box, when necessary, can be extracted immediately to avoid the kind of chaotic phenomenon. Category Memory law is the core of this word learning programs memory, the memories Law, the other three methods are based on the classification of large properties or properties in accordance with a further breakdown, from big to small, from whole to parts , layer depth, some have a section, structure complete and clear. Full course is divided into seven categories: Most commonly used word around; And cases most commonly used root words; Prefix and the case of the most frequently used words; Cases most commonly used suffixes and word; Most frequently used phrasal verbs; Most frequently used words in English news; Most commonly used foreign words in English. We have seven major categories on the basis of further subdivision, so the maximum extent possible for the learners to establish clear and stringent word learning structure. Roots affixes Memory Method is the most effective method of word memory. Using this method can achieve replicability, largely rebutted those claims of magical effects, can be said to have roots affixes memory, the words that we can solve life problems! Roots affixes Memory Method is the most effective method of word memory. This view by many linguists and professionals widely recognized. Using this method can achieve replicability, largely rebutted those claims of magical effects, learners can in the shortest period of time memorizing vocabulary. If we look at the history of English can fully accept this view. The Development of English is divided into three periods: Old English (Old English), AD 450 ~ 1150; Middle English (Middle English), AD 1150 ~ 1500; Modern English (Modern English), from 1500 to the present.

Latin influence on English very deep. Roots affixes it to the Latin majority. The Eastern European culture is a different branch of the Indo-European, but also of Latin descent. Middle English period is the period of French rule in the United Kingdom, English borrowed words from French and from the derived form new words. The Modern English period is because the prevalence of English in the world, from a variety of languages by word and form. And with the technology and economic development, constantly creating new words. Review of English history we find, in fact, mainly through the new English vocabulary words learn other languages as the basic root, then create the basis formed with affixes. Statistics show that so far, English words have more than 2 million, and the constant growth every day. So, memorize words and heretical obviously does not work, root word affix a large memory is the most scientific method of English vocabulary learning, as long as we first command of about 1,000 root affixes, we can inferred to contain such a root Affix the meaning of new words, the real effect of replication. Roots affixes and because usually shorter, easy to remember, very few spelling errors will occur. So through the root affixes memory, the words that we can solve life problems! Very taboo word learning and memory fragmented, unrelated words. Our original scenario associative memory lets you quickly set up the scene frame, triggering scenes Lenovo, a high degree of scope to expand memory. Very taboo word learning and memory fragmented, unrelated words. If there is no relationship between the word or link, is easy to forget after you remember, unless you after repeated use and memorize. Our original scenario associative memory can help you to easily overcome a bad memory, easy to forget the difficulties. The word we learning courses based on a word by the subordinate to classify the scene then, and the word the other words are listed out the framework for users to set up the scene, triggering scenes Lenovo, a high degree of scope to expand memory. For example: the scene, &quot;I&#39;m at home&quot; module, we have listed the room, basic facilities, living room, bedroom, bathroom, kitchen, dining room, children room, workshop, hall, electrical appliances, skin care cosmetics, clothing bags, standing drug and commonly used tools 15 parts, each part of the eye that you can enumerate and, mental thought almost all items.

In this way, you recall the &quot;I&#39;m at home,&quot; the word, under the guidance in this scenario, you would think of all the relevant words.

Advantage of this classification is accurate for you to establish the overall framework, and based classification framework, focused on capturing the same part of speech, this method allows you to quickly find a certain word in common cause and effective association, times to expand the scope of memory; it is highly targeted, can do all break, sharply, received strange effect!
