    Attention！Sunshine Language Learning Centre will set a course and it will teach Pure（纯正的） British English. Maybe you've known some British expressions are quite different from American ones。British people use “autumn” for “fall”, “film” for “movie”. “holiday” for “vocation”, “garden” for “yard”. etc

    There are more typical（典型的）expressions that you may not know. Here are Mr. Bean's examples.

    Are you interested in it? Do you want to learn? You can learn British English well if you put much effort into it. We have some native British English teachers with much experience to help you.

    The course will be open in the coming summer holiday. The price of the course is not very high: ￥500 for one person; ￥900 for two（10% off）; ￥1,200 for three (20% off); for four or more(30% off).
