　　The glasses can play back memories later to help the wearer remember things they have forgotten such as where they left their keys. And the glasses also 49 the user to "label" items so that information can be used later on. The wearer could walk around an office or a factory identifying certain 50 by pointing at them. Objects indicated are then given a 51 label on a screen inside the glasses that the user then fills in.

　　It could be used in 52 plants by mechanics looking to identify machine parts or by electricians wiring a 53 device.

　　A spokesman for the project said: "A car mechanic for 54 could find at a glance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could 55 accident black spots or dangers on the road."

　　In other cases the glasses could be worn by people going on a guided tour, 56 points of interest or by people looking at panoramas where all the sites could be identified.

　　[A] allow [B] instance[C] blank[D] industrial[E] frustrating[F] items

　　[G] indicating[H] highlight [I] user [J] complicated [K] white

　　[L] annoying [M] successful [N] article [O] simple

　　答案解析

　　47. E 空格处需填一形容词，即从E、J、L、M中选择。过去分词一般用于主语是人的句子，排除J;结合常理，忘性大常常令人懊恼，故E最符合文章。

　　48. I 根据定语从句谓语see可知，主语要么是人要么是眼镜，由下句the use的提示，故选I。

　　49. A 该空需填入一个动词，即从备选项A、H中选择，有allow sb. to do sth.的结构，且语义符合文意，故选A。

　　50. F 由上文的label items可推知F最符合文意。

　　51. C 该空需填入一个形容词，由下文的fill in可推知C(空白的)最符合文意。

　　52. D 由该句中的相关信息词mechanics(机械师)和identify machine parts可推知D最符合文意。

　　53. J 该空需填入一个形容词修饰名词device(设备)，由常识可知工厂里的设备通常都很复杂，正因为复杂，不容易记住，才有必要使用这种新型眼镜，故J最符合文意。

　　54. B 该句主句的基本句子结构是A car mechanic could find where a part is，介词for和应填的词在句中作插入万分，结合选项，B最符合文意。

　　55. H 该空应填入动词原形，从词义上能排出A，H符合文意。

　　56. G 分析句子结构可知，该空应填入一个非谓语动词，结合句意“在其他情况下，人们可以戴着这种眼镜随团旅游，________名胜景点…”可知，G(指示)最符合文意。
