题目内容

【题目】Several traffic accidents have happened recently．If drivers are careful enough，most accidents ．

A．can prevent B．can be prevented

C．need prevent D．will prevent

【答案】B

【解析】

试题分析：句意：最近发生了几起交通事故，如果司机们都很小心的话，大多数事故是可以阻止的。Accidents是prevent这一动作的承受者，该用被动语态。而含有情态动词的被动语态形式是“情态动词+be+实意动词的过去分词”，所以选B。

【题目】 Many homes have cameras to protect them from danger. The cameras can tell the owners if someone has entered. But the cameras do not know whether the person is a family member, a friend, a postman or a criminal (罪犯).

But a new camera made by a French company can recognize (辨别出) faces. It can tell parents at work that their children have returned from school, or that the mail has been sent to their home. It can also tell them if a stranger has entered their home. When family members enter a home, the smart camera “recognizes” them and sends information to the owner’s phone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send a warning sound on the owner’s phone.

This is what happened recently to a smart home camera owner named Damien. He lives in Paris.

“On a Friday I was at work, having a big monthly meeting when my phone moved. At first I told myself ‘Oh, it must be a wrong warn,’ but my phone was telling me there was a face that the camera did not recognize. Something was happening in my house!”

“I saw a person I did not know with his shoes on, which is not allowed in my apartment (公寓). I watched it on the video. I felt quite surprised. I hurried back home as fast as possible and called the police on the way. Thanks to the smart camera, the criminal was caught soon,” said Damien.

A. wear shoesB. watch videos
