阅读理解。 Dear Mom, I'm sorry that I can't go back home for Mother's Day next week. On that day, I'll have to go to an important meeting for my boss, who helps me a lot with my work and life here. But I'll find time to see you at home soon. Mom, thank you for everything you've done for Tim and me. After Dad died ten years ago, you had to work in a supermarket in the daytime and in a restaurant at night. But you always gave us two your love and care. Though you don't have to work now, I still remember your coming home and feeling tired many evenings. Tim is going to finish his studies next month. He said he would move back from school and look for a job neat home. I'm glad you won't live by yourself anymore. Let's plan to take a trip in the near future. It's been years since the three of us took a trip together. Happy Mother's Day. I love you, Mom. Best wishes, John 1. What can we learn about John's mother? A.  She lives by herself now.
