A.will give B.will have given C.will be given D.will have been given 答案：D 解析：由时间标志词“By the time you arrive”（到你到达时为止)可知主句用将来完成时；主语 “VR devices”是动作“give”的承受者，需用被动语态，结构为“will have been+过去分词”，give 的过去分词为given。 真题2（语法填空)： The project (complete)by the end of next month will allow users (experience) a fully immersive VR world. 答案：to be completed;to experience 解析：第一空，“by the end of next month”提示动作在将来某时前完成，project与complete是被动 关系，用不定式的被动式“to be completed”作定语；第二空，固定搭配“allow sb.to do sth.”(允 许某人做某事)，填“to experience”。 考法三：将来完成时综合应用与时态对比 核心：结合时间状语从句的时态搭配规则，区分主动/被动语态，对比将来完成时与一般将来时、现 在完成时的用法差异 真题1（单项选择)： 高中选择性必修第三册重庆大学版 【寒假专版】 语法全解 By the time our teacher back,all the homework and submitted. A.comes will have been finished B.will come will be finished C.comes will finish D.has come has been finished 答案：A 解析：by the time引导时间状语从句时，主句用将来完成时，从句用一般现在时表将来，故第一空 填comes;homework与finish是被动关系，需用将来完成时被动语态will have been finished,A项 符合语法规则。 真题2（语法填空)： Scientists predict that humans (live)on Mars for 10 years by 2100,and the first Mars city (build)by then as well. 答案：will have lived,:will have been built 解析：第一空由时间状语by2100可知需用将来完成时，表示持续到将来的动作；第二空city与build 是被动关系，同样用将来完成时被动语态，结构为will have been+过去分词。 解题小妙招 将来完成看标志，by加将来是信号： 主动结构主+will have done,.被动will have been done: by the time从句表将来，一般现在时来引导： 动作完成在将来前，主动被动要分辨： 般将来只表动作发生，现在完成着眼过去到现在： 对比区分不混淆，结合语境准判断。 真题演练 将来完成时专项练习 语法填空（用所给词的适当形式填空） 1.By the time you(reach)the station,the train(leave).(reach;will have left) 2.The workers(finish)the bridge by the end of next year.(will have finished) 3.Before he_(come)back,I(clean)the entire house.(comes;will have cleaned) 4.This novel_(translate)into 10 languages by 2025.(will have been translated) 5.Maybe she(read)all the books before the vacation_(end).(will have read;ends) 高中选择性必修第三册重庆大学版 【寒假专版】 语法全解 句型转换（将下列主动句改为被动句） 1.They will have completed the tunnel by next March The tunnel_by next March.
