He’ll be back next Monday. A．has been B．has gone C．went D．goes 【答案】B 【详解】句意：——你的爸爸在哪里？——他去北京出差了，他下周一回来。 根据“He’ll be back next Monday”可知爸爸现在不在此地，还没有回来。has gone to表示“去了某地（人未返回）”，故填has gone。 5．—Where is Tom? —He ________ Shanghai for a summer volunteer program. He won’t return until next Friday. A．has been to B．has gone to C．went to D．has been in 【答案】B 【详解】句意：——汤姆在哪里？——他去上海参加暑期志愿项目了，要到下周五才回来。 has been to去过，已经回来了；has gone to去了，还未回来；went to去了，一般过去时；has been in待在某地，后接时间段。根据答句“He won’t return until next Friday.”可知，说明Tom现在不在此地，还没有回来，应填has gone to。 6．Many wonderful changes ________ in our town since the new policy came out. A．took place B．take place C．have taken place D．will take place 【答案】C 【详解】句意：自从新政策出台以来，我们镇上发生了许多可喜的变化。 根据时间状语since the new policy came out（自从新政策出台），since是现在完成时的标志词，强调从过去持续到现在的变化，应填have taken place。 7．Grandma has lived in this small village ________ she was twenty years old. A．for B．since C．when D．until 【答案】B 【详解】句意：奶奶自从二十岁起就住在这个小村庄里。 for长达；since自从；when当……时候；until直到……为止。根据“has lived”可知，主句时态是现在完成时，表示动作从过去持续到现在；“she was twenty years old”是过去的时间点，应用since引导时间状语。 8．—________ your family ________ to the new apartment yet? —Yes, we moved there last month. A．Did; move B．Have; moved C．Will; move D．Do; move 【答案】B 【详解】句意：——你的家人已经搬到新公寓了吗？——是的，我们上个月搬那里了。 根据疑问句末尾的“yet”可知，该句应用现在完成时，其结构为“have/has+过去分词”。 9．— ________ you ________ the story of Zhong Nanshan? — Yes, he is a real hero who saved thousands of lives. A．Did; hear B．Have; heard C．Will; hear D．Do; hear 【答案】B 【详解】句意：——你听说过钟南山的故事吗？——是的，他是一位拯救了成千上万生命的真正的英雄。 根据语境可知，问句询问的是过去的经历对现在造成的影响，强调“是否听说过”，应用现在完成时。主语是“you”，助动词用Have，hear的过去分词是 heard。 10．I have ________ my grandma every day since she moved in. A．see B．saw C．seen D．seeing 【答案】C 【详解】句意：自从奶奶搬进来后，我每天都见到她。 根据句中助动词“have”及“since she moved in”可知，本句为现在完成时，结构是“have/has +过去分词”，see的过去分词是seen。 11．—You look very smart in this new suit today. —Thanks. But to tell you the truth, I ________ it for quite a few years. A．had B．bought C．have had D．have bought 【答案】C 【详解】句意：——你今天穿这套新西装看起来很精神。——谢谢。但说实话，这套衣服我已经拥有好多年了。   had意为“拥有”，是一般过去时；bought意为“买”，是一般过去时；have had意为“拥有”，是现在完成时，have bought意为“买”，是现在完成时。句中时间标志“for quite a few years”表示一段持续的时间，句子要用现在完成时，现在完成时中和一段时间连用时，必须使用延续性动词，buy是非延续性动词，不能和for引导的时间段连用，要转换成对应的延续性表达have，应填have had。 12．—Mum, I’ve ________ all the milk. Can you buy some? —Sure. I’ll go to the supermarket in a minute. A．ran out of B．run out of C．run out D．been run out 【答案】B 【详解】句意：——妈妈，我已经喝完所有牛奶了，你能买一些吗？——当然，我马上就去超市。 run out of主语是人，表示“某人用完某物”，后面必须接宾语；run out主语是物，表示“某物用光了”，后面不能接宾语。I’ve是I have的缩写，句子时态为现在完成时，后接过去分词；run out/run out of没有被动语态，本句空格后有宾语all the milk，所以用run out of，run的过去分词还是run。 13．My parents ________ for over twenty years. A．have married B．have been married C．got married D．were married 【答案】B 【详解】句意：我的父母已经结婚二十多年了。 marry，get married为短暂性动词（短语），不能与“for+时间段”连用；be married表状态，可持续。“for over twenty years”是持续时长，要用现在完成时表持续状态，应选have been married。 14．He ________ his keys. He can’t find them anywhere. A．loses B．lost C．has lost D．will lose 【答案】C 【详解】句意：他把钥匙弄丢了，他到处都找不到它们。 后文“can’t find them anywhere”，找不到钥匙是现在的状态，强调过去的动作对现在造成的影响，应用现在完成时，其结构为have/has done，主语为He。应填has lost。 15．—How long ________ you ________ here? —For 6 years. A．have; been B．have; gone C．did; arrive D．do; stay 【答案】A 【详解】句意：——你在这里待了多久了？——6年了。 have been表示状态，可延续；have gone强调去了未回，为瞬间动作；did arrive为一般过去时且arrive是瞬间动词；do stay为一般现在时。根据答语“For 6 years”可知，句子时态应为现在完成时，且谓语动词需为延续性动词。结合语境，应选have; been。 16．I ________ my hometown for three years. I really miss it. A．left B．have left C．have been away from D．was away from 【答案】C 【详解】句意：我离开家乡已经三年了。我真的很想念它。 left离开；have left已经离开；have been away from已经离开；was away from远离。根据时间状语“for three years”可知，句子应用现在完成时，且谓语动词需用延续性动词。have been away from是现在完成时的可延续状态结构，既可以和“for+时间段”搭配，也能表达从过去离开家乡持续到现在已经三年的含义，符合语境。have left里的leave是瞬间动词，不能和持续三年的时间段连用。应选have been away from。 17．Many young workers ________ back to work in villages in recent years. A．come B．came C．have come D．will come 【答案】C 【详解】句意：最近几年，许多年轻工人已经回到乡村工作。 根据时间状语“in recent years”可知，动作发生在过去并对现在造成影响，应用现在完成时，结构为“have/has+ 过去分词”。应填have come。 18．— Hi, Mark! Long time no see! — Hey, Jenny! I ________ you for ages. How’s everything going? A．have come to see B．have known C．haven’t seen D．have met 【答案】C 【详解】句意：—— 嗨，马克！好久不见！ ——嘿，珍妮！我好久没见到你了。一切进展如何？ have come to see已经过来见 ；have known已经认识 ；haven’t seen很久没见到；have met已经遇见。根据“Long time no see”和“for ages”可知，此处表达“我很久没见你了”，haven’t seen符合现在完成时的语境，其他选项不符合句意。 19．________ Kieran Behan was 10 years old, he has dreamt of competing in the Olympics. A．Since B．When C．While D．Until 【答案】A 【详解】句意：自从基兰·贝汉10岁以来，他就梦想参加奥运会。 Since自从……以来；When当……时候；While当……期间；Until直到……为止。根据主句“he has dreamt”是现在完成时，从句“was”是一般过去时，可知此处表示动作从过去持续到现在，应用Since引导时间状语从句。 20．—Our hometown ________ a lot in the past few years. The roads are wider and the rivers are cleaner. —Yes. Great changes have taken place around us. A．has changed B．changed C．changes D．was changing 【答案】A 【详解】句意：——在过去的几年里，我们的家乡变化很大。道路更宽，河流更清了。——是。我们周围发生了巨大的变化。 时间状语“in the past few years”是现在完成时的标志，表示过去发生的动作对现在造成的影响，结构为 “have/has+过去分词”，主语“Our hometown”是单数，助动词用has，空处填has changed。 21．The lovely rabbit ________ of the box and ran across the grass. A．jump out B．jumped out C．jump away D．jumped away 【答案】B 【详解】句意：这只可爱的兔子从箱子里跳出来，跑过草地。 “ran”表明句子的时态为一般过去时，谓语动词需用过去式；jump out of为固定搭配，意为“从……跳出来”，符合“兔子从箱子里跳出来”的语境，jump away通常不与of连用。应填jumped out。 22．The great writer ________ at the age of 88, and people still remember his works today. A．pass away B．passed away C．pass off D．passed off 【答案】B 【详解】句意：这位伟大的作家在88岁时去世，人们至今仍记得他的作品。 pass away去世；pass off发生，冒充。根据“at the age of 88”和“people still remember his works today”可知，作家已故。根据时间状语“at the age of 88”可知，动作发生在过去，谓语动词用过去式passed。 23．He ________ to devote more time to protecting local plants. A．made up his mind B．makes up mind C．make up his mind D．made up mind 【答案】A 【详解】句意：他下定决心投入更多时间来保护当地植物。 固定短语“”make up one’s mind to do sth.”意为“下定决心做某事”，其中“one’s”需与主语He保持一致，应用his，排除B、D；如果是一般现在时，主语He是第三人称单数，谓语动词应用单数形式，C选项make是原形，排除C。A选项“made up his mind”时态为一般过去时和搭配均符合。 24．I ________ read children’s books, but now I prefer novels and science books.

A．didn’t; until B．didn’t; after C．won’t; until D．isn’t; after 【答案】A 【详解】句意：他昨晚直到完成作业才去睡觉。 until直到；after在……之后。根据时间状语“last night”可知，句子时态为一般过去时，助动词需用didn’t；“not...until...”为固定搭配，意为“直到……才……”，“didn’t; until”符合句意逻辑。 28．The wonderful idea ________ not ________ at the very beginning.
