A. produced B. invented C. discovered D. created 25. The new educational invention is ______ and easy to operate for students. A. expensive B. inexpensive C. difficult D. useless 答案与解析： 1. C 解析：主语radio message（无线电讯息）与动词send为被动关系，时间状语in 1901为一般过去时，故用一般过去时被动语态was sent。 2. A 解析：invent意为“发明（新事物）”，蔡伦发明造纸术是创造新事物；invite邀请，discover发现（已有事物），create创作，均不符合语境。 3. B 解析：固定句型make it + adj. + for sb. to do sth.（使某人做某事……），此处用不定式to spread。 4. C 解析：also意为“也”，句意为这种胶水既能粘东西，也能轻松取下；still仍然，yet然而，never从不，不符合句意。 5. A 解析：固定短语to one’s surprise（令某人惊讶的是），为单元核心短语，其余搭配均不成立。 6. B 解析：主语toys and chairs与make为被动关系，nowadays提示一般现在时，故用一般现在时被动语态are made。 7. A 解析：connect此处表示“连接、贯通”，描述客观事实用一般现在时，主动形式即可，无需被动。 8. D 解析：主语the word与introduce为被动关系，in 1920为过去时间，用一般过去时被动was introduced。 9. A 解析：creative意为“有创造力的”，修饰发明家的思维，符合单元发明家主题；common普通的，simple简单的，均不符合语境。 10. B 解析：make用于被动语态时需还原不定式to，机器是被启动工作，故用will be made to。 11. A 解析：result in意为“导致、促成”，造纸术促成了文化传播；result from起因于，不符合逻辑。 12. A 解析：根据课文可知，造纸术出现前，竹简、丝绸等书写材料昂贵、不便，expensive符合文意。 13. A 解析：固定搭配meet difficulties（克服、遭遇困难），为单元核心搭配。 14. A 解析：固定短语pieces of paper（纸片），为单元重点短语。 15. B 解析：increase侧重“增长、促进（经济、旅游）”，improve侧重“改善（状态、条件）”，此处旅游业发展用increase。 16. B 解析：主语camera与connect为被动关系，描述产品固有功能，用一般现在时被动is connected。 17. A 解析：固定搭配by itself（独自、自动地），主语the machine为单数，用反身代词itself。 18. C 解析：fast的比较级为faster，现代发明让信息传播更快，符合单元主旨；slowly语义相反。 19. C 解析：主语tunnels与create为被动关系，青藏铁路修建是过去的事，用一般过去时被动were created。 20. B 解析：固定搭配be helpful for doing sth.（有助于做某事），介词for后接动名词improving。 21. A 解析：change civilizations（改变文明进程），贴合课文中古代发明影响世界的主旨。 22. B 解析：because of后接名词/代词，表原因；because后接从句，此处the radio为名词短语。 23. A 解析：easy和fast的比较级分别为easier、faster，并列结构直接连用，无需重复more。 24. A 解析：produce此处意为“生产、研制出”，侧重实验产出物品，贴合胶水研制的语境。 25. B 解析：根据单元发明展览要求，优质发明需价格低廉、操作简单，inexpensive意为“便宜的”。 二、根据句意，用括号内所给单词的适当形式填空。 1.
