听力原文：Woman: I need a screwdriver. Do you mind if I borrow yours？
Man: Go right ahead. It's in my toolbox in the closet, but please don't forget to return it soon. I don't want to lose it, and I'll need to use it later, anyhow.
Woman: Don't worry. You'll have it back before lunch. I just need it for a few minutes to tighten up some screws on this bookshelf.
Man: Just put it on my desk when you're done. I'll use it to fix that squeaky chair before. I go home tonight.
What does the woman want to borrow？
听力原文： Wilton K. Smith, the local business entrepreneur who was well-known to town residents for his many eccentricities, died at his home last night. He was ninety-three years old. Mr. Smith is survived by his son, Wilton K. Smith Jr., and two grandchildren. Don't expect his survivors to take over his business, however. Mr. Smith was estranged from his son and grandchildren for many years, and he left his entire estate to his dog, a spaniel named Charles. Man's best friend inherited over two million dollars. Will he continue his deceased owner's business, or invest it all in dog food？ That remains to be seen. Funeral services for Mr. Smith will be held next Sunday at one o'clock at Brown's Funeral Home on Third Street. The dog is expected to attend.
How much was the man's estate worth？
