四、用方框中所给单词的适当形式填空。每词限用一次。

22. Some necessary rules to keep students safe already.
23. Many Chinese astronauts heroes for their great contributions.

25. Most students couldn't understand the sentence until it in class.

21.be carried 22.have been made
23.are considered 24.will be shown
25.was explained

【分析】本题考查动词的适当形式填空，核心是被动语态的运用。解题时需先判断每个句子中主语与所给动词的主被动关系，再结合句中的时间标志词或语境确定时态，最后匹配被动语态的结构（be+过去分词），填入正确形式。
【解析】
21. 主语Mobile phones是动词carry的承受者，需用被动语态；情态动词shouldn't后接动词原形，故填be carried。
22. 主语rules是动词make的承受者，且句中有时间标志词already，需用现在完成时的被动语态（have/has been+过去分词），主语为复数，故填have been made。
23. 主语astronauts是动词consider的承受者，句子描述客观事实，用一般现在时的被动语态（are+过去分词），故填are considered。
24. 主语exhibits是动词show的承受者，句中有时间标志词next week，需用一般将来时的被动语态（will be+过去分词），故填will be shown。
25. 主语it指代sentence，是动词explain的承受者，主句为一般过去时，until引导的时间状语从句用一般过去时的被动语态（was+过去分词），故填was explained。
【答案】21.be carried 22.have been made 23.are considered 24.will be shown 25.was explained
【知识点】被动语态、时态辨析
【点评】本题聚焦被动语态在不同时态中的应用，要求学生掌握被动语态的基本结构及不同时态下的变形，是初中英语语法的核心考点，需准确判断主被动关系与时态标志。
