　　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;結合常理，忘性大常常令人懊惱，故E最符合文章。

　　2. I 根據定語從句謂語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.的結構，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(設備)，由常識可知工廠里的設備通常都很復雜，正因為復雜，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構是A car mechanic could find where a part is，介詞for和應填的詞在句中作插入萬分，結合選項，B最符合文意。

　　9. H 該空應填入動詞原形，從詞義上能排出A，H符合文意。

　　10. G 分析句子結構可知，該空應填入一個非謂語動詞，結合句意"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。

　　For many environmentalists, the world seems to be getting worse. They have developed a hit-list of our main fears: natural resources are __1__ out the population is ever growing, leaving less and less to eat? Species are becoming __2__ in vast numbers, and the planet's air and water are becoming ever more polluted.

　　But a quick look at the facts shows a different picture.

Second, more food is now produced per __4__ of the world's population than at any time in history. Fewer people are __5__. Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 25~50%, as has so often been __6__. And finally, most forms of environmental pollution either appear to have been __7__, or are transient - associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by __8__ it. One form of pollution - the release of greenhouse gases that causes global warming - does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to __9__ a devastating(令人心神不安的) problem. A bigger problem may well turn out to be an inappropriate response to it.
