It seemed incredible that he had been there a week already.

t

ous

ear

lievable

【本题来源】2013年职称英语理工类B词汇选项第16题

【本题考点】近义词辨析

【正确答案】D

【题 干】真让人难以置信，他已经在那里待了一个星期了。

A.正确的 B.显然 C.不清楚 D.不可置信的

【解 析】考查形容词。划线词inCredible意为“难以置信的，惊人的”，故选择D。

【考点延伸】本题仍然是in.(否定前缀)+credible的构词方式，正确选项也采取同样 的方式un-(否定前缀)+believable=不可置信的。常用的否定前缀有un./in-/dis-/mis-/non-.等。常见的否定后缀有-less。

The tower remains intact ever after two hundred years.

own

ual

maged

able

【本题来源】2013年职称英语理工类A词汇选项第6题

【本题考点】近义词辨析

【正确答案】B

【题 干】这座塔在两百年后依然保持完好无损。

【解 析】考查形容词。划线词intact意为“完整的，原封不动的，为受损害的”，与undamaged在语义上一致，故正确答案为C。

【考点延伸】un一表示否定，如unimportant(不重要的)，uncertain(不确定的)。

The weather was crisp and clear and you could see the mountains fifty miles away.

A. fresh

B. hot

y

D. windy

【本题来源】2012年职称英语理工类A词汇选项第4题

【本题考点】近义词辨析

【正确答案】A

题意：空气清新，50里以外的山峦都能看到。

句子中crisp的意思是新鲜的.。

A中fresh的意思是新鲜的，新的;例句：open the window and let in some fresh air.打开窗户，让新鲜的空气进来。

B中hot的意思是热的，辣的;例句：This dish is a bit hot.这道菜有些辣。

C中heavy的意思是重的;例句：The lead is heavy and the plastic is light.铅是重的，而塑料是轻的。

D中windy的意思是有风的;例句：Hold on to the hat on a windy day.在有风的日子里请紧紧抓住帽子。故选A。

research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.

research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.

uters currently use electrons to transfer information and process applications. On the other hand, data sources such as the internet rely on optical systems; the transfer of information using light. Optical fibres are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signalsonce they reach a computer, causing a significant slowdown in processing.

4."The challenge is to find a single material that can effectively use and control light to carry information around a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.

5."This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as 'pn-junction' devices. This should enable the material to act as a light source, a light guide and a light detector - something that can carry and interpret optical information. In doing so, this could transform the computers of tomorrow, allowing them to effectively process information at much faster speeds."

researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.

(单项选择题)Paragraph 3 _____

ctation of the discovery

problem of current computers

C.A new finding

purpose of the research

ic reaction to the discovery

use of the new material

【答案】B

【考点】2015

【解析】由第三段第一句话Computers currently use electrons to transfer information and process applications.可知，现如今的电脑是同电信号进行信息交换的，后文有提及了这种交流可能存在的问题，故可知答案为B。其中currently暗示答案为B。
