These days people who do manual work often receive far more money than people who work in offices.People who work in offices are often referred to as"white-collar workers”for the simple reason that they usually wear a collar and tie to go to work.
【正确答案】：坐办公室的人之所以常常被称作“白领工人”，就是因为他们通常是穿着硬领白衬衫、系着领带去上班。【解析】原句是主从复合句，主句是被动语态，谓语动词be refered to as译为“被称作”，who work in offices是修饰people的定语从句，汉译时前置。they usually wear a collar and tie to go to work是reason的同位语，汉译时将reason译作“是因为”，更符合汉语的表达习惯。
