1、2022年考博英语-西南交通大学考前提分综合测验卷（附带答案及详解）1. 单选题The laser represents a true marriage between science and technology in that the men who devised it were （ ）engineers and physicists.问题1选项A.spontaneouslyB.homogenouslyC.instantaneouslyD.simultaneously【答案】D【解析】句意:激光代表了科学和技术的真正结合，因为发明激光的人同时是工程师和物理学家。考查副词辨析。sponta
2、neously 自发地；自然地；homogenously 同样地； instantaneously突如其来地；即刻；simultaneously同时地。根据前半句句意可知这里表示“发明激光的人既是工程师，也是物理学家”，故选D。2. 单选题（ ）conflict among city-states caused the eventual decline of Greek civilization.问题1选项A.ContinuousB.ContinualC.ConstantD.Contrary【答案】B【解析】句意:城邦之间的持续冲突导致了希腊文明的最终衰落。考查形容词辨析。continuous
3、和continual都有“连续的，持续的”意思，但continuous强调“不间断”而continual 强调“频繁，反复”。Constant 不变的，恒定的；contrary 相反的，对立的。这里是用来形容城邦间的冲突，故选B。3. 单选题“Oh, Im too sleepy to study.” “Well, if you （ ） that late movie last night, you wouldnt have been so sleepy.”问题1选项A.didnt watchB.havent watchedC.havent watchedD.hadnt watched【答案】D
4、【解析】语法题。考查虚拟语气。分析题干可知if you （ ） that late movie last night是if引导的条件状语从句，从主句部分的wouldnt have been可知此句是对过去事实的虚拟，因此从句部分应用had+过去分词形式，故选D项。句意：“哦，我太困了不能学习。”。“嗯，如果你昨晚没有观看那个晚场的电影的话，你不会如此困。”4. 单选题（ ）man can now create radioactive elements, there is nothing he can do to reduce their radioactivity.问题1选项A.AsB.Whe
5、therC.WhileD.Now that【答案】C【解析】句意:虽然人类现在可以制造出放射性元素，但无法降低这些元素的放射性。考查连词辨析。前半句句意为:人类现在可以制造出放射性元素，后半句句意为:无法降低这些元素的放射性。由此可见，前后为转折对比的关系，因此C项“虽然，尽管”正确。5. 单选题In the wake of 11 September, Visionics, a leading manufacturer, issued a fact sheet explaining how its technology could enhance airport security. They
6、called it protecting civilization from the faces of terror. The companys share price skyrocketed, as did the stocks of other face-recognition companies, and airports across the globe began installing the software and running trials.As the results start to come in, however, the gloss is wearing off.
7、No matter what you might have heard about face-recognition software, Big Brother is not so good as expected.The concern was based largely on an independent assessment of face-recognition systems carried out in 2000 in the U.S. by the Department of Defense. These tests found that to catch 90 percent
8、of suspects at an airport, face-recognition software would have to raise a huge number of false alarms. One in three people would end up being dragged out of the line and thats assuming everyone looks straight at the camera and makes no efforts to disguise himself. Results from the recent airport tr
9、ials would seem to justify that concern.Most face-recognition systems use some kind of geometric technique to translate a picture of a face into a set of numbers that capture its characteristics. Once it has identified these boundaries, the software calculates their relative sizes and positions and
10、converts this geometry into what Visionics calls a faceprint. Feed the software a series of mugshots and itll calculate their faceprints. Then it can monitor live CCTV images for the faces of known suspects. When it finds a match, it raises an alarm.Even if the system does manage to capture a face,
11、the problems arent over. The trouble is that a suspects faceprint taken from live CCTV is unlikely to match the one in the database in every detail. To give themselves the best chance of picking up suspects, operators can set the software so that it doesnt have to make an exact match before it raise
12、s the alarm. But theres a price to pay: the more potential suspects you pick up, the more false alarms you get. You have to get the balance just right.Despite the disappointing tests, some people insist that face-recognition technology is good enough to put terrorists off. After all the claims and c
