It seems you always forget-your reading glasses when you are rushing to work, your coatwhen you are going to the cleaners, your credit card when you are shopping...

　　Such absent-mindedness may be 1 to you; now British and German scientists aredeveloping memory glasses that record everything the 2 sees.

　　The glasses can play back memories later to help the wearer remember things they haveforgotten such as where they left their keys. And the glasses also 3 the user to "label" items sothat information can be used later on. The wearer could walk around an office or a factoryidentifying certain 4 by pointing at them. Objects indicated are then given a 5 label on a screeninside the glasses that the user then fills in.

　　It could be used in 6 plants by mechanics looking to identify machine parts or byelectricians wiring a 7 device.

　　A spokesman for the project said: "A car mechanic for 8 could find at a glance where apart on a certain car model is so that it can be identified and repaired. For the motorist thesystem could 9 accident black spots or dangers on the road."

　　In other cases the glasses could be worn by people going on a guided tour, 10 points ofinterest or by people looking at panoramas where all the sites could be identified.

　　答案解析：

　　1. E 空格處需填一形容詞，即從E、J、L、M中選擇。過去分詞一般用于主語是人的句子，排除J;結(jié)合常理，忘性大常常令人懊惱，故E最符合文章。

　　2. I 根據(jù)定語從句謂語see可知，主語要么是人要么是眼鏡，由下句the use的提示，故選I。

　　3. A 該空需填入一個動詞，即從備選項A、H中選擇，有allow sb. to do sth.的結(jié)構(gòu)，且語義符合文意，故選A。

　　4. F 由上文的label items可推知F最符合文意。

　　5. C 該空需填入一個形容詞，由下文的fill in可推知C(空白的)最符合文意。

　　6. D 由該句中的相關(guān)信息詞mechanics(機械師)和identify machine parts可推知D最符合文意。

　　7. J 該空需填入一個形容詞修飾名詞device(設(shè)備)，由常識可知工廠里的設(shè)備通常都很復(fù)雜，正因為復(fù)雜，不容易記住，才有必要使用這種新型眼鏡，故J最符合文意。

　　8. B 該句主句的基本句子結(jié)構(gòu)是A car mechanic could find where a part is，介詞for和應(yīng)填的詞在句中作插入萬分，結(jié)合選項，B最符合文意。

　　9. H 該空應(yīng)填入動詞原形，從詞義上能排出A，H符合文意。

　　10. G 分析句子結(jié)構(gòu)可知，該空應(yīng)填入一個非謂語動詞，結(jié)合句意"在其他情況下，人們可以戴著這種眼鏡隨團旅游，________名勝景點…"可知，G(指示)最符合文意。
