Rose wanted a job. She went to many offices and she didn’t like any of them. One day she saw a board in an office read: “This office needs a typist whom can type 200 words a minute.” Rose was exciting. She then went to the manager’s office. Rose knocked at the door and the manager raised her head. “Do you need a typist?” asked Rose. “Yes!” he said. Rose clapped(拍) her hand and asked, “OK!
