Explain the following terms 一1) free morpheme/ A free morpheme is one that can be uttered发出,表达alone with meaning. It can exist on its own without a bound morpheme. In the traditional sense, a free morpheme is a word. 例如hand ,eat, get 2) bound form/never used as sentences. – ess in countess, lioness and duchess –ish in boyish, childish and greenish –s in hats, books and cups 3) function words/ function words are often short words, they do not have much lexical meaning and some of them have no lexical meaning of their own; They are often short words such as determiners限定词, conjunctions连词, prepositions介词, auxiliaries辅助物, and so forth. 如to, the , of , by 4) content words实词/ They are used to name objects, qualities, actions, processes or states, and have independent lexical meaning. They are the nouns, main verbs, adjectives形容词and adverbs副词of a language. 二1) syntheti c综合的language / inflectional grammatical markers, French, German and Russian. 2) analytic language/word order, prepositions or auxiliary verbs , English and Chinese 3) Indo-European family of languages/ Europe and parts of Southern Asia Eight groups 三1) morphemes /The morpheme is the smallest meaningful linguistic unit of language, not divisible可分的or analyzable into smaller forms. 2) allomorphs/variants变体of the same morphem如im-, ir-, il- : allomorphs of the morpheme in- 3) root / is the basic unchangeable part of a word, and it conveys the main lexical meaning of the word. work able, work er, work ed, and work ing 4) stem /A stem is of concern only when dealing with inflectional morphology.

英语词汇学怎么考 英语词汇学必背知识点

英语词汇学怎么考英语词汇学必背知识 点 英语词汇学考试难吗?那么该课程怎么考?要知道英语考试并不是一蹴而就的,所以考前应该日记月累的学习,在最后考试的时候才能更好的通过考试,我们来看看英语词汇学必背知识点吧。 英语词汇学怎么考 英语词汇学是一门理论知识课,每个知识点应该说都重要,所以重点和一般本来就难以界定。从掌握知识来说,不要去分重点和一般,对每章每节都要以搞懂弄通为原则。 1、考前重点词汇复习方法 要知道语法填空重点考查的词:动词、形容词、副词和派生词。其中重点是动词,要把考点的设置与拼写的可能形式结合起来(如从谓语动词的角度来看,就要 考虑动词的时态、语态和主谓一致所带来的动词变化。其中过去式是考查重点,所以对动词的过去式,尤其是不规则动词的过去式和过去分词的拼写,自然就成为后期复习的重点。至于另外三大词类也完全可以如此类推。
2、词汇积累学习

加强短文背诵,增强“词不离句”意识。背诵是非常原始的英语学习方法,但也是非常积极、有效的学习方法。优选一些名家名篇,做为背诵的素材;或从课文中精选一些精悍之作,作为研习的精典,不但能够迅速提高语感,而且容易激发兴趣,形成活生生的词库,为单词的准确使用打下良好的基础。 3、英语主观题拿分技巧 首先是单词拼写,这是所有题目中考生得分最低的一个部分,通常平均分不超过3分,所以大家不要太在意,20个单词,对4个,能有2分就很不错了,如果想要提高这部分,大家还要有准备的背单词,因为这里面的单词,并不全是课本课后单词表的单词,其中很多都是以前在中学学过的,所以要准备这一部分,需要的是买一本自考英语的词汇大纲,按里面的词汇背记才有意义。 如果大家对英语词汇学课程学习有难度,那么可以通过在线视频学习的,以上三点就是学赛小编对英语词汇学必背知识点学习方法,希望大家能更好的学习。 点击进入>>>
