I've been learning Japanese since October. She has been working in Singapore since 2014. How long does it take to rain? Mary has been looking for a job for six months. Kitty has been traveling for the last 4 months. She taught this subject for 5 years. Sam is very tired. He worked hard all day. Did you call Tony? Yes, she called today. She was preparing for the exam the last few days. Laurie studied at the library for the last 6 hours. We planned this train for months.
