    王思远，琅邪临沂人。尚书令晏从弟也。宋建平王景素辟为南徐州主簿，深见礼遇。景素被诛，左右离散，思远亲视殡葬，手种松柏。与庐江何昌宇、沛郡刘琏上表理之，事感朝廷。景素女废为庶人，思远分衣食以相资赡。

    建元初，迁太子中舍人。文惠太子与竞陵王子良素好士，并蒙赏接。思远求出为远郡，除建安内史。长兄思玄卒，思远友于①甚至，表乞自解，不许。及祥日②，又固陈，世祖乃许之。

    世祖诏举士，竞陵王子良荐思远及吴郡顾暠之。思远与顾暠之友善。暠之卒后家贫，思远迎其儿子，经恤甚至。邵陵王子贞为吴郡，世祖除思远为吴郡丞，以本官行郡事，论者以为得人。以疾解职，还为司徒谘议参军。高宗辅政，不之任，仍迁御史中丞。临海太守沈昭略赃私，思远依事劾奏，高宗及思远从兄晏、昭略叔父文季请止之，思远不从，案事如故。

    建武中，迁吏部郎。思远以从兄晏为尚书令，不欲并居内台权要之职，上表固让。曰：“陛下矜遇之厚，古今罕俦。正以臣与晏地惟密亲，必不宜俱居显要。且亦缘陛下以德御下，故臣可得以礼进退……”上知其意，乃改授司徒左长史。

    初，高宗废立之际，思远与晏闲言，谓晏曰：“兄荷世祖厚恩，今一旦赞人如此事，彼或可以权计相须，未知兄将来何以自立。若及此引决，犹可不失后名。”晏不纳。及拜骠骑，集会子弟，谓思远兄思微曰：“隆昌之末，阿戎③劝吾自裁。若从其语，岂有今日？”思远遽应曰：“如阿戎所见，犹未晚也。”及晏败，故得无他。

    思远清修，立身简洁。衣服床筵，穷治素净。宾客来通，辄使人先密觇视。衣服垢秽，方便不前；形仪新楚，乃与促膝。虽然，既去之后，犹令二人交帚拂其坐处。上从祖弟季敞性甚豪纵，上心非之，谓季敞曰：“卿可数诣王思远。”永元二年卒，年四十九。

——《南齐书》卷四十三列传第二十四王思远传》

根据短文理解，选择正确答案。

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.
