A: We'd like to welcome everyone to the Michelson Tools factory site, and thank everyone for being here today. My name is Paul Shafer, I'll be showing you around today. Please feel free to ask questions at any point during our tour, I'll be happy to answer questions for you.

B: is it really necessary to wear all this protective gear?

A: that's an excellent question. I'll bet your wondering why we ask you to wear hard hats and safety googles while you's in the plant. The reason is simple, we care about your safety and we want to ensure there are no injuries today. As you will see, to maintain a high level of safety, we also require all of our staff to wear similar protective gear.

B: how long will the tour take?

A: it should take about twenty minutes to go through the main plant, and maybe another ten to take a look at the laboratory. All together our tour should last about half an hour.

B: Okay...

A: well, if you don't have any questions, shall we get started? If you'll follow me, first I'll take you to the site of our semi-conductor system...

欢迎大家来到迈克尔逊工厂,非常感谢今天到场的诸位嘉宾.我叫保罗.夏飞,今天由我来带领大家参观.参观期间请随时提问,我乐于为大家解答.

真的有必要戴上这种防护装备吗?

这个问题提得不错.我敢说你们一定想知道参观工厂时我们为什么要求你们戴上工程帽和护目镜.原因很简单,我们担心诸位的安全,要确保今天不出现任何受伤现象. 你们还会看到,为了保证绝对安全,我们要求员工也戴上同样的防护装备.

多长时间能参观完?

参观主要生产车间需要20分钟,也许再有10分钟去看一下实验室,总共大约需要半个小时.

好的…

好了,如果没有问题,我们可以开始吗? 请大家跟着我走,我们先去参观半导体生产车间…
