How time flies! Now this term is coming to an end. Outside, snowflakes are falling quietly. The campus is covered with snow and is very beautiful. But few people are in the mood to enjoy the beautiful scenery. Most people are busy in the college. The teachers are preparing the examination papers. The students are reviewing their lessons. Most students in Mr. Green's class are practicing reading or writing in English. They are helping each other. Now Mr. Green is in Mr. Wang's office. They are talking about the students. 


Mr. Green: Look, all the students are working hard. I've never
                 seen this before.
Mr. Wang: Good for them. They may feel a bit nervous about the
                  coming exams.
Mr. Green: They must be very tired. They've stayed in the
                  classroom for too long a time.
Mr. Wang: Yeah. We'd better try to get the students relaxed.
Mr. Green: Shall I take them out for a while in the fresh air?
Mr. Wang: Good idea! It's snowing outside. Let's take some
                  photos with the students.
