解析
【分析】首先通读短文理解主旨，再针对每个空格，结合语法规则、固定搭配、词性转换等知识逐一分析：1. 空格前有many，需用可数名词复数，对应invent的名词形式；2. 考查固定短语搭配；3. 考查动词不定式结构；4. 考查并列连词的使用；5. 考查词性转换（动词变名词、形容词变副词等）；6. 考查现在完成时的用法（结合时间状语since）；7. 考查固定短语的名词复数形式；8. 考查形容词作表语的结构。
【解析】
31. 空前many修饰可数名词复数，invent的名词是invention，复数为inventions，故填inventions；
32. 固定搭配a longer time表示“更长的时间”，故填a；
33. 固定短语instead of意为“代替”，故填of；
34. 固定搭配want to do sth，故填to cross；
35. 前后是并列动作，用连词and连接，故填and；
36. produce后接名词，electric的名词是electricity（不可数），故填electricity；
37. 修饰动词have需用副词，real的副词是really，故填really；
38. 时间状语since 2 years ago提示用现在完成时，主语a pair of...为单数，故填has helped；
39. 固定短语take photos表示“拍照”，用复数形式，故填photos；
40. 固定搭配be successful in doing sth，需用形容词，success的形容词是successful，故填successful。
【答案】31. inventions 32. a 33. of 34. to cross 35. and 36. electricity 37. really 38. has helped 39. photos 40. successful
【知识点】固定搭配、词性转换、动词时态
【点评】本题为语篇填空题，主要考查学生对基础词汇的词性变化、常用固定短语及语法（时态、介词）的掌握，需结合上下文语境分析，整体难度适中，适合初中阶段学生练习。
