题目内容

【题目】Could you tell me ? I must find him.

Sorry, I'v no idea. But he was here just now.

A. where Tom was B. where Tom has gone

C. where can I find Tom D. where Tom has been

【答案】B

【解析】

句意:——你能告诉我汤姆去哪儿了吗?我必须找到他。 ——对不起,我不知道。但他刚才在这里。本题主要考查宾语从句。根据语境,你能告诉“我”汤姆在哪里吗。where 引导的宾语从句在句中作 tell 的直接宾语,me 为间接宾语。宾语从句使用陈述语序,故此处应用“where + 主语 + 谓语”的结构,主语为 Tom,谓语为 be 动词。故排除C项。根据语境时态和主句时态保持一致Could you tell me表示请求允许后用现在完成时,has gone是指去某地,没回来;has been指从某地回来了。结合语境可知是指Tom去了某地。故选B。

【题目】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(跟踪) 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 through a Bluetooth wireless(无线的) 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 dentist actually watch your brushing on a day-to-day basis," says Thomas Serval, the French inventor(发明家).

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

Serval says he got the idea 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, from $99 to $199, and the U.S. is the first target market.
