想提高英语专业水平

有没有能够提高焊接英语能力的资料或网站,长期系统的学习下

学习英语最重要的就是语言环境,要经常跟别人交流,交流多了,你掌握的单词就多了,再学习其他的语法知识效果就好多了,你可以尝试着先提高自己口语,我之前找了许多家都是由于各种原因没学好,后来自己上网找了几个比较了一下,就是在家跟老外交流,学习英语,是小班授课,一个班4-8个人,小班课程开口机会很多,挺不错的,叫 乐知英语 ,各个级别的课程都有,是在线授课的形式,在家和老师就可以互动的交流,很方便,不用跑来跑去,老师质量非常的好,而且都是在国外的中外教,非常的地道,课时数很多,性价比很不错,而且每晚都有免费的试听课程可以体验,很透明,价格也挺不错的,有时间可以先上去免费试听一下啊,每晚的免费试听课程可以到这里看下,希望能对你有帮助哦 http://www.hiknow.com/sessionhall.html

多看看现成的专业资料吧,中英文对照的资料最好,帮助很大
要是想练口语,就多跟老外交流吧
