少儿英语口语学习的10个等级

家有儿女的家长们,如果你家中有宝宝学英文的话,那么对照以下10个阶段,就能清楚地知道孩子的英语口语水平处在哪个级别了,瑞思学科英语资深教育专家认为,孩子学英语,要从兴趣、热情入手,然后不断练习演讲演示,点滴各界才能过到“口语之王”的水平。 1. Enthusiasm 1. 积极热情 万事开头难,有了兴趣和热情,学习英语口语不再是难事。 2.

Lack of Understanding 5. 缺乏理解 学习英语,如果全都理解了才能学通的话,就大错特错了,以有知来推测未知,才是学英语的最佳方法。 6. Frustration 6. 挫折 凡事都不是一帆风顺的,学习英语也如此。 7. Revelation 7. 新发现 在学习的路上,总有新发现,新刺激,这样才能一直激励着你一路向前。 8.

3E英语三笔四口总体介绍与分析 3E少儿英语(听、读、写)三级测评形式:笔试测评:试卷时间:60分钟 一、听力部分【均为4个选项】【35分】: 1、听句选答(8分)难度系数★★ Tips:情景对话为主,对于有些习惯用法需要让孩子掌握。比如,me too, me either; i think so, i disagree等,孩子要了解这些句子表达的意思。 2、对话理解(10分)难度系数★★ 听对话,选出最恰当的答案。 Tips:对于这部分听力中的数字、方式、颜色、具体的细节等有相当的要求。由此,孩子需要提高的除了英语基础之外,对于听力的方法和技巧有一定的要求。 3、听短文做总结(7分)难度系数★★★ 顾名思义,听到短文后,在理解句意的情况下,按照顺序把单词填入文中。 Tips:比一般的spot dictation稍难一点。而且要求顺序是一致的。对于速记要求比较高 4、长对话理解、短文听力理解(10分)难度系数★★ 听长对话和短文,选出最恰当的答案。 Tips:这部分内容多,信息量大。孩子需要提高的除了英语基础之外,对于听力的方法和技巧有相当的要求。 二、读写部分 1、语法与词汇【40分】 PartA 【25分】单选 Tips:中考之内的基本语法点。包括各种词性及其用法,八大时态、特殊疑问词、易混淆动词的用法需要熟练掌握。 PartB【15分】完形填空 Tips:2篇,一篇长,一篇短。类似于前三笔。这是孩子损失惨重的一部分。要求孩子对于上下文的理解、句意推测、词语意义和用法比较了解并熟悉运用。

2、阅读理解【15分】3篇阅读 Tips:信息量大,一定要帮助孩子养成带着题去看文章的习惯,提高做题速度。 3、写作【10分】给一个话题让孩子对于话题进行阐述。比如:What do you do on Monday? Tips: 学会使用复合句进行写作是制胜关键。 难度分析: 从听力和语法的难度来讲,可以比对新概念二的难度。新概念二的1-60课基本覆盖了三笔的难点。听力部分,对于平时缺乏练习的孩子来看,难度比较大。制胜策略就是让孩子复述,参考书目是中考听力。 分析:从三级考试的内容来看,听力侧重于句子和文章的理解。对于孩子的英语思维要求较高,理解句子的上下文意思,对于文中信息要有一定的筛选能力。有一定的听力学习技巧。 攻略:1、复述2、关键字3、速记有此三宝,英语听力必完胜。 词汇语法部分基本涵盖了中考范围内的基本语法点,尤其注重易混淆词汇的搭配和理解;不同时态的基本用法和关键提示语要让孩子有这方面的意识。另外,死伤最惨重的还是在完形填空上。对于时态、词意、词语搭配等要求较高;孩子一定要熟练背诵常用固定搭配,才能降低出错的几率。 攻略:1、固搭要熟背;2、时态要理会;3、易混词语分清楚;4、错题再做对。 阅读理解三部曲:看题---阅读---筛选。带着题去看文章可以大大提高孩子的做题效率。三笔和二笔的不同之处在于,文中的生僻字和信息量会大出很多。孩子在没有良好的阅读习惯的情况下很容易读不下去。所以,在做阅读这方面,习惯重于能力。 写作----语言的综合运用正好体现在这个部分。对于长难句型一定要多背,多练。参考书籍来看,新概念二是个不错的选择。背写结合,对于孩子帮助更大。 3E少儿英语口语四级测评形式:口语测评:人机对话时间:6-8分钟 1.常识问答(6题):答对4个以上通过该项目。 Tips: 这部分内容非常简单,为四口必过项目。背诵文化常识部分注意几个要点:
