题目内容

【题目】They didn't discover until they happened to enter the back room _________ someone had stolen the priceless painting.

A.thatB.whatC.whichD.when

【答案】A

【解析】

考查宾语从句连接词。句意:直到他们碰巧进入后屋,才发现有人偷了那幅无价的画。分析句子可知,“有人偷了那幅无价的画”在句中作动词discover的宾语,所以是宾语从句,从句缺少引导词,而宾语从句中又不缺少任何成分,所以用连接词that引导该宾语从句。因为that在名词性从句中不做成分,无词意,而其它几个选项都是要在从句中做一定的句子成分的。故选A

The human face is a remarkable piece of work. The astonishing variety of facial 1 helps people recognize each other and is crucial to the formation of complex societies. So is the face’s ability to send emotional 2, whether through a(n) 3 blush or a false smile. People spend much of their waking lives, in the office and the courtroom as well as the bar and the bedroom, reading faces, for signs of attraction, hostility and trust.

Technology is rapidly catching up with the human ability to read faces. In America facial recognition is used by churches to 4 worshippers’ attendance; in Britain, by retailers to spot past shoplifters. This year Welsh police used it to arrest a(n) 5 outside a football game. In China it verifies the identities of ride-hailing drivers, 6 tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to 7 the homescreen.

Set against human skills, such applications might seem gradual. Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode them. Although faces are 8 to individuals, they are also public, so technology does not, at first sight, intrude on something that is private. And yet the ability to record, 9 and analyze images of faces cheaply, quickly and on a vast 10 promises one day to bring about fundamental changes to notions of privacy, fairness and trust.
