在我高二那年，我代表学校去法国参加了为期十五天的文化交流活动
In my second year in high school, I attended school for 15 days of the French cultural activities

在那里我认识了Marlene，一开始，我们通过打手势交流，我还经常使用字典，后来，我们的英文水平都有所提高，沟通也越来越自如！
I know where Marlene, at the outset, we have to make a gesture, I would often use a dictionary, but we have to raise the level of English communication more easily
