large language model is viewed as a major breakthrough in the field of generative AI，状语从句中主语和主句主语一致，且从句中有be动词时，可省略从句中的主语和be动词，因此空格处是viewed。故填viewed。 18．If (paint) green, the door might look more

repaired properly...”。主语 the machine（机器）和动词 repair（修理）之间是被动关系（机器是被修理的），所以要用过去分词 repaired。故填repaired。 22．If (admit) to a university, you’d better make a plan in advance so as to fully enjoy your college life. 【答案】admitted 【详解】考查非谓语动词。句意：如果你被大学录取，你最好提前制定一个计划，以便充分享受你的大学生活。此处是 if 引导的条件状语从句的省略，从句主语与主句主语一致，且含有 be 动词，故省略了主语 you 和 be 动词。admit 与主语 you 之间是被动关系，应用过去分词形式，be admitted to 意为“被…… 录取”。故填

was，保留过去分词asked。故填asked。 24．Our plan would work out smoothly unexpected difficulties arise. 【答案】should 【详解】考查情态动词。句意：即便发生意外困难，我们的计划也会照常顺利进行。should在此处引导条件从句，是 if...should 结构的省略倒装形式。原正常语序为：If unexpected difficulties should arise, our plan would work out smoothly.，省略 if 后，should提至从句句首，形成倒装结构（should+主语+动词原形），属于正式或书面用语，强调假设的可能性。故填should。 25．If (burn) severely, he should be given some first aid immediately. 【答案】burnt/burned 【详解】考查状语从句中的省略结构。句意：如果被严重烧伤，他应该立即接受急救。这是if引导的条件状语从句的省略结构，当条件状语从句主语与主句主语一致，且从句谓语含有be动词时，可省略从句的主语和be动词；逻辑主语“he”与动词“burn”之间为被动关系，因此用过去分词形式burnt/burned，完整形式为If he is

her childhood，主语she与attach“使牵连，使依附”为被动关系，本空用过去分词，与was构成一般过去时的被动语态，省略she was，保留过去分词attached。故填attached。 27．If (put off) by over three minutes, D5122 would have made Wang’s attempt fail. 【答案】put off 【详解】考查状语从句中的省略。句意：如果延迟超过三分钟，D5122就会让王的尝试失败。此处用了If引导条件状语从句，从句无主语，为省略形式，对主语和be动词同时进行了省略，put off“延迟”和D5122之间是被动关系，因此用put off的过去分词形式，结合“would have made”可知，从句用了虚拟语气，完整形式为If it had been put off…。故填put off。 28．While (preserve) the core tradition, Zeng Fanyu innovates boldly to develop new flavors. 【答案】preserving 【详解】考查状语从句的省略。句意：在坚守核心传统的同时，Zeng Fanyu大胆创新，开发新口味。此处while引导状语从句，Zeng

eventually. 【答案】challenged 【详解】考查非谓语动词。句意：尽管受到资源有限的挑战，我们团队最终还是交付了一款出色的产品。此处为although引导的让步状语从句的省略结构，“challenge”与逻辑主语“our team”之间为被动关系，所以此处使用过去分词形式challenged，完整形式为“Although our team was challenged by

opinion, he will always tell you the truth. 【答案】asked 【详解】考查状语从句的省略。句意：如果被问及他的意见，他总是会告诉你真相。当if引导的条件状语从句的主语与主句主语一致，且从句含有be动词时，可省略主语和be动词。完整形式为“If he is asked about his opinion”，省略“he
