关于英语学习英语难学吗?说难确实难,很多人天天不忘背单词,读课文,但几个月下来却发觉收效甚微,英语水平老是提不上去。

但如果说容易也并不为过,even a child can do it! 确实有些人感觉学好英语是那么自然的事情,甚至不费吹灰之力。

每个人的英语学习能力是不一样的,学习能力主要是通过学习方法来体现的;一个人的能力与他的天资相关,但主要还是通过后天的培养形成的。

我想大家都应该知道这样一个道理:如果你三天打鱼,两天晒网,你可能终生不能学会;如果你能以持之以恒的态度去学习,学好英语是没有问题的,持之以恒的学习是一个知识积累的过程。

每一个能学好英语的人都应该是积极的,注重积累的。

其实对于其它的学习,何尝又不是一样呢?,因此,假如您真的希望学好英语,首先您应该知道,学习语言是一个长期的过程,是一个不断学习积累的过程,积累到一定的程度,自然就能“滔滔不绝”、“脱口而出说英语”,正所谓“厚积薄发”。

当然在积累的同时我们不能忽略了学习方法的重要性,因为它能给我们带来极高的学习效率。

值得我们借鉴的学习方法很多,例如:钟道隆先生的“英语学习学习逆向法”,黎学智教授的“英语词汇逻辑记忆法”,李阳的”疯狂英语“等都是一些非常成功和有影响的的学习方法。

但是把别人介绍的各种方法变成自己的东西要有一个过程。

看了几遍书上介绍的学习方法,似乎理解了,其实不一定。

因为“感觉到了的东西,我们不能立刻理解它,只有理解了的东西纔能更深刻地感觉它”,只有在自己的不断实践中一步一步领会各种方法的要领。

正如俗语所说的,“师傅领进门,修行在个人”。

在学习别人介绍的各种方法时,也不要过分迷信这些方法而限制了自己的创造性。

只有用心思索,不断总结,找出适合自己情况的特有的学习方法来是最有效的。

还要说的一点就是学习兴趣的培养,很难想象一个人能够持之以恒去做一件自己毫无兴趣甚至让他感到厌烦的东西,因为那简直就是一种折磨!又怎么会取得良好的效果呢?在现实中不乏一些对英语头疼但迫于考试或者其它压力又不得不学英语的人,如果这种”症状“出现在您的身上的话,不必为其而忧虑,因为英语学习并不可怕,其实在学习中还是有很多乐趣的,您不觉得很多经典的欧美歌曲是那么的动听吗?您不觉得很多外文的DVD配上中文显得那么的别扭难听,而希望听到纯正的原声吗?再看些英文幽默故事吧,你会发现英文有时是多么的可爱!还有英文小说,它同样具有让你心动和意犹未尽的情节!...慢慢的挖掘吧,不妨暂时避开那些会让你觉得头疼的内容,找一些相关的但你感兴趣的东西,兴趣培养起来了,想学不好都难了!提醒您:1.英语学习贵在坚持2.要养成良好的生活习惯3.要有计划的学习4.你一定可以学会“英语”因为您很小的时候就学会了说:外国人觉得异常难学的“汉语”,不妨想想你到底是怎么学会[听]、[说]、[读]、[写]汉语的?先学拼音?汉字、词?然后学习造句?再读课文?对了,老师还老要求我们写令人头痛的作文?再是你迷上了看小说、散文、诗歌?还有呢?平时天天都在说?还是根本就不知道怎么学会的呢?那就是不知不觉吗?学拼音花了多长时间?学常用汉字花了多少时间?学会写简单的作文花了多少时间?看中文数据您花了多少时间呢?后来你怎么又会写长篇大论了呢?其它的语言学习是否也是如此呢?英语学习是不是呢?语音?单词、词组?造句?学课文?写作文?小说?多读?多听?多写?多说?5.多阅读各种英文数据,积累知识,并从中寻找乐趣,让自己学得乐不思蜀,自然不会因为厌烦而半途而废了。
