Questions 1-4 refer to the following e-mail from a teacher to a student.

Dear Michelle,

Thanks for your e-mail about the homestay program in Switzerland. I understand your worries. I was (1)... with a new family before I did it, too! The family I stayed with was very kind. Actually, they were surprised (2)..... my ability to speak German. At that time, I was below your level, so you don't need to worry. (3).... to learn a new language is to immerse yourself in it. By the way, students from my other German classes will be going, too. If you (4).... meeting them, I can give you their contact information.

Best,

Mr. Roth
