IX. Read the following passage, then choose the best answer to each of the following questions Dear John, How are you? I’m still working on a farm, but unfortunately I’m going to leave here at the end of winter. Let me tell you why. We had terrible time a month ago. Thousands of insects came and ate many of the crops in the fields. The farmer is very worried because he thinks the insects will come again and destroy all the crops. He became so worried that he sold the farm last week, and that is why I have to leave here. Soon I will have to look for another job. Do you think you could help me find one? I like working on farm, so if you know anyone who needs a hard worker, please recommend me to them. I know that you are very busy at the moment and that you don’t have much free time. But I really hope you can find time to help me. I don’t know what else to do. If I can’t find a job, I will have to go back home and stay with my parents. I know they would be very upset if I did that. They are old and they don’t have much money. They couldn’t support me as well as themselves. I hope to hear from you soon.
