       夏洛克:我的意思已经向殿下告禀过了;我也已经指着我们的圣安息日起誓,一定要照约执行处罚;要是殿下不准许我的请求,那就是蔑视宪章,我要到京城里去上告,要求撤销贵邦的特权。您要是问我为什么不愿接受三千块钱,宁愿拿一块腐烂的臭肉,那我可没有什么理由可以回答您,我只能说我欢喜这样,这是不是一个回答?要是我的屋子里有了耗子,我高兴出一万块钱叫人把它们赶掉,谁管得了我?这不是回答了您吗?有的人不爱看张开嘴的猪,有的人瞧见一头猫就要发脾气,还有人听见人家吹风笛的声音,就忍不住要小便;因为一个人的感情完全受着喜恶的支配,谁也做不了自己的主。现在我就这样回答您:为什么有人受不住一头张开嘴的猪,有人受不住一头有益无害的猫,还有人受不住咿咿唔唔的风笛的声音,这些都是毫无充分的理由的,只是因为天生的癖性,使他们一受到刺激,就会情不自禁地现出丑相来;所以我不能举什么理由,也不愿举什么理由,除了因为我对于安东尼奥抱着久积的仇恨和深刻的反感,所以才会向他进行这一场对于我自己并没有好处的诉讼。现在您不是已经得到我的回答了吗?

       巴萨尼奥:你这冷酷无情的家伙,这样的回答可不能作为你的残忍的辩解。

       夏洛克:我的回答本来就不是为了讨你的欢喜。

       巴萨尼奥:难道人们对于他们所不喜欢的东西,都一定要置之死地吗?

       夏洛克:哪一个人会恨他所不愿意杀死的东西?

       巴萨尼奥:初次的冒犯,不应该就引为仇恨。

       夏洛克:什么!你愿意给毒蛇咬两次吗?

    Many people traveled to Las Vegas, Nevada last week for the 50th Consumer Electronics Show, or CES. The show is said to have the largest collection of new electronic devices in the world.

    The show had many examples of “smart home” devices. “Smart home” technology is designed to make life easier for people by letting computers control many things inside our homes. One such device actually begins working outside the home, when someone arrives and rings the doorbell.

    “When someone comes to your front door and rings the doorbell, the light can turn on immediately. I get a notification when I'm halfway around the world that someone came, and I can start talking to the person who's at my front door, and I can say, 'Oh, here let me let you in,' I can unlock the door for them very easily.” Said Vivint, a smart home service provider.

    One electronics maker launched a device that lets people see and interact with their animals when they are away. The device, from Petcube, lets you remotely watch and talk to your pet through a personal device, according to a company official. It can even give the pet a treat—if you approve and order it.

    For heating or cooling, there is a smart thermostat. This device can also send you a message if a big storm causes leaks of flooding. “We're trying to catch it with just a few drips before it becomes a real big problem,” said Mike Sale of iDevices.

    A concern for many homeowners is the possibility that someone else might find a way to attack these smart home devices. An official from Vivint said his company is sure that only owners of the home can gain use of information on the devices. Warren Katz from iDevices said his company employs engineers from the defense industry to help prevent hacking.
