    Mike works very long hours every day. He usually gets up at 17:00. He has a shower and makes his breakfast. What a funny time to make breakfast! After breakfast, he practices (练习) his guitar for ten minutes, then he puts on his jacket and goes to work. To get to work, he takes the No.17 bus to the Star Hotel. The bus usually leaves at 19:15.
