如何激发学生学习英语的兴趣?

As a Chinese teacher, how can I raise my students’ interest so that they learn English on their own initiative?
作为一名中国教师，我如何激发学生学习英语的兴趣，使他们能够做到主动学习?
Students are always more motivated when they regard English as a means to an end, rather than an end in itself. Compare the attitudes of young pupils who are told repeatedly that English will be extremely important to them in their lives, and the attitudes of students who find they need English for a particular purpose (say to study medicine or law). The former are quickly bored; the latter are highly motivated. The way to raise motivation among young pupils is to set them project work, where English is a means to an end. For example, if you set pupils the task of finding out about the history of Hong Kong, this will be their prime objective and English will be a by-product of the process.
当学生们意识到英语能够作为实现某种目的的手段时，他们对英语的学习才会有动力。让我们看看小学生对学习英语的态度吧! 他们反复被告诫英语在他们生活中扮演极其重要的角色；再看看另外一些学生对英语学习的态度，为了实现某种目的(比如说为了学习医学或法律)，他们感觉到有学好英语的必要。前者很快对英语的学习感到厌烦，而后者则显示出强烈的学习动机。激发小学生的学习积极性的方式就是给他们布置一些课堂活动，并规定只能通过英语这一工具完成。比如，如果你给学生布置查找有关香港历史的作业， 便是他们的首要目的，而对英语的使用是这一过程的副产品。

8.How should I teach students grammar in my teaching?
教学过程中，我该如何教语法呢?
Modern textbooks concentrate on teaching communication (=how to do things in a foreign language). Grammar is the natural by-product of this undertaking. This means, you teach grammar not as an end in itself, but as a support system to communication. Most of the questions students have about English concern grammar (when to use some or any, when to use to or at and so on). Deal with these as they arise. When dealing with grammar, extract as much information as you can from your students and then set them exercises to raise their awareness of particular grammatical points, but always do this after you have trained them in communicative skills like listening comprehension, using language for a purpose, etc. 
现代教材着重教授交流能力(=如何用外语这个工具做事情)。语法是这一任务的副产品。这就是说，你并不是为教语法而教语法，而是把它当成交流的辅助体系。学生在英语学习过程中所遇到的大多数问题是有关英语语法的(例如，什么时候用some或者any,什么时候用to或者at，等等)。问题出现时，立即解决。在解决有关语法的问题时，要从学生们那儿获得尽可能多的信息，然后给他们设置一些旨在培养他们对具体语法点的感悟的练习。但这些一定要在让学生得到足够的交流能力(如理解、语言的运作，等等)训练之后进行。
