　　听力原文

　　Questions 32 to 35 are based on the passage you have just heard。

　　Since a union representative visited our company to inform us about our rights and protections. My coworkers have been worrying about health conditions and complaining about safety hazards in the workplace. Several of the employees in the computer department, for example, claim to be developing vision problems from having to stare at a video display terminal for about 7 hours a day. The supervisor of the laboratory is beginning to get headaches and dizzy spells because she says it’s dangerous to breathe some of the chemical smoke there. An X-rays technician is refusing to do her job until the firm agrees to replace its out-dated equipment. She insists that it’s exposing workers to unnecessarily high doses of radiation. She thinks that she may have to contact the Occupational Safety and Health Administration and asked that government agency to inspect the department. I’ve heard that at a factory in the area two pregnant women who were working with paint requested a transfer to a safer department, because they wanted to prevent damage to their unborn babies. The supervisor of personnel refused the request. In another firm the workers were constantly complaining about the malfunctioning heating system, but the owners was too busy or too mean to do anything about it. Finally, they all met an agree to wear ski-clothing to work the next day. The owner was too embarrassed to talk to his employees. But he had the heating system replaced right away。
