【分析】本题为单句语法填空题，主要考查动词时态语态、固定搭配、词性转换等知识点。解题时需先分析每个句子的结构、时态、语态，判断空格处所需的词性或成分，再结合语境、固定短语及语法规则确定正确形式。例如，涉及被动关系的句子需用被动语态，表方式的用介词by，形容词后接名词，固定短语需牢记等。
【解析】1. 主语the high-speed train与动词develop是被动关系，时间状语in the 1960s表过去，故用一般过去时的被动语态，结构为was+过去分词，填was developed。
2. 主语a pair of sunglasses与use是被动关系，描述客观事实用一般现在时，故用一般现在时被动语态，结构为is+过去分词，填is used。
3. 此处表示“通过积累塑料”的方式，介词by可表方式，填by。
4. be made by是固定搭配，意为“由……制作”，后接动作执行者，填by。
5. 形容词useful后需接名词，invent的名词形式为invention，填invention。
6. hundreds of是固定短语，表不确定数量“成百上千的”，填hundreds。
7. be connected to是固定搭配，意为“连接到……”，填to。
8. all by oneself是固定短语，主语为it，反身代词用itself，填itself。

10. be used for doing sth是固定搭配，意为“被用于做某事”，填for。
【答案】1. was developed 2. is used 3. by 4. by 5. invention 6. hundreds 7. to 8. itself 9. to help 10. for
【知识点】动词时态语态、固定搭配、词性转换
【点评】本题为初中英语单句语法填空的典型题型，考查核心基础语法与常用固定搭配，知识点覆盖全面，难度适中，适合巩固基础语法。
【难度系数】0.6

三、阅读理解
We all know that many inventions have changed our life a lot. They play important roles in our daily life. Here are some interesting inventions.
Morpher
People refuse to wear helmets（头盔）because they're thick and heavy. Morpher is a bike helmet made of plastic. It is just as strong as traditional helmets, but it can be folded almost completely flat, making it easier to carry. Morpher may be available for sale in stores in the near future.
Hyperadapt
Have you ever seen the movie Back to the Future? Maybe everyone wants the pair of shoes in the movie that can tighten or loosen by themselves. Now, thanks to the Shoe Factory, the dream is realized. When you push a button on the shoe, Hyperadapt can tighten or loosen around the feet.
