Just speak like you always do. Thx~
Days ago, I got an English partner, we are both preparing for TOEFL test, so we talk to each other a lot mainly to improtve our English.
Every day at night, we will talk about what we did today, some interesting things and some bad memories, too. We share with each other and encourage each other. That will help us better master the usage of English.
Also, because we are both applying for universities in the US, so we share information and give advice to each other, too. So I think we are more than just English partners, we are friends, too.
