A．remember B．return C．recycle 【答案】C 【详解】句意：下列单词中哪个“re-”的含义与单词“reuse”中的含义相同？ 考查前缀辨析。reuse中前缀re-意为“再，又，重新”。remember记住，re-表“回”；return返回，re-表“回”；recycle回收利用，re-意为“再，重新”，与reuse中的含义一致。故选C。 2．In the words “retell” and “reuse”, what does “re-” mean? A．very B．more C．again 【答案】C 【详解】句意：在“retell（复述）”和“reuse（再利用）”这些单词中，“re-”是什么意思？ 考查词缀含义。very非常；more更多；again再一次。在英语单词里，“re-”作为前缀，常表示“再一次、重新”的意思。“retell”意思是重新讲述，也就是再一次讲；“reuse”意思是再次使用。所以“re-”在这里表示“again（再一次）”。故选C。 3．—Jeff, ________ the film? —Yes, I ________ it last month. A．did you see; have seen B．have you seen; saw C．do you see; saw 【答案】B 【详解】句意：——杰夫，你看过这部电影吗？——是的，我上个月看了。 第一空询问是否经历过某事，强调对现在的影响，应用现在完成时have you seen；第二空根据时间状语last month可知是明确的过去时间，需用一般过去时saw。 4．I ________ to Beijing last year, but I ________ never ________ to Shanghai. A．went; have; been B．will go; have; been C．went; have; gone 【答案】A 【详解】句意：去年我去了北京，但我从来没去过上海。 第一空，根据时间状语last year可知，句子时态为一般过去时，动词用过去式went；第二、三空，根据never可知，句子时态为现在完成时，have been to表示“去过某地”，强调经历，have gone to表示“去了某地”，强调人未回。此处表示从未有过去的经历，应用have been to。 5．It has been three years ________ we graduated from primary school. A．when B．since C．until D．before 【答案】B 【详解】句意：自从我们小学毕业已经三年了。 when当……时；since自从；until直到；before在……之前。根据“has been three years”可知，本句为现在完成时，应用since引导。 6．Artificial Intelligence (AI) ________ a hot topic in technology for the past few years. A．becomes B．became C．has become D．will become 【答案】C 【详解】句意：人工智能（AI）在过去的几年里已经成为科技领域的热门话题。 时间状语“for the past few years”意为“在过去的几年里”，是现在完成时的标志，表示动作从过去持续到现在。结构为“have/has+过去分词”，主语AI是第三人称单数，助动词用has。 7．—Is that Chris speaking? —Sorry, he isn’t in. He ________ abroad on business. A．has gone B．has been C．has been in 【答案】A 【详解】句意：——是克里斯在讲话吗？——对不起，他不在。他去国外出差了。 has gone去了（未回）；has been去过（已回）；has been in待在（某地）。根据“Sorry, he isn’t in.”可知，克里斯现在不在这里，说明他去国外出差还没有回来，表示“去了某地未回”，应填has gone。 8．— What a nice watch! How long ________ you ________ it? — For just two weeks. A．will; buy B．have; had C．were; having D．have; bought 【答案】B 【详解】句意：——多么漂亮的手表！你拥有它多长时间了？—— 仅仅两周。 根据疑问词“How long”和答语“For just two weeks.”可知，句子应用现在完成时，且谓语动词必须是持续性动词。buy是瞬间性动词，不能与时间段连用，故排除D项；A项是一般将来时，C项是过去进行时，时态不符。have表示“拥有”，是持续性动词，符合语境。故选B。 9．He _________ his hometown in 2021. He _________ from it for five years. A．has left; has left B．left; has left C．left; has been away 【答案】C 【详解】句意：他2021年离开了家乡，他已经离开它五年了。 left离开；has left已经离开；has been away已经离开。第一空有时间状语in 2021，表示过去某个时间发生的动作，需用一般过去时，故填left。第二空有for five years，表示从过去持续到现在的状态，需用现在完成时，且必须使用延续性动词，leave是短暂动词，不能与时间段连用，因此用has been away，构成has been away from it，故填left；has been away。 10．You are welcome!

A．have joined B．have begun C．have been in D．have been on 【答案】C 【详解】句意：不客气！事实上，我已经在健康心灵俱乐部待了半年了。我就是在那里学到这些的。 have joined已经加入；have begun已经开始；have been in已经在……里面（持续了一段时间）；have been on（节目、活动等）已经开始进行。根据时间状语“for half a year”可知，句子强调状态持续了一段时间，谓语动词需用延续性动词。join和begin是瞬间动词，不能与时间段连用；be in表示状态，是延续性动词，符合语境。 11．I ________ this book for three weeks. I have to return it now.

We are still sad about her ________. A．died; dead B．has been dead; dead C．has been dead; death 【答案】C 【详解】句意：他的祖母已经死了两年了。我们对她的死亡仍然感到很悲伤。 考查时态以及词义辨析。die死亡，动词；dead死亡的，形容词；death死亡，名词。for+时间段是现在完成时的标志，后需用延续动词，die死亡，瞬间动作，延续性动词是be dead，排除A。形容词性物主代词her后接名词，故选C。 13．—How long ________ you ________ this book? —For a week. A．have; kept B．have; borrowed C．did; borrow 【答案】A 【详解】句意：——这本书你借了多久？——一周。 考查现在完成时中的延续性动词。根据问句以及“For a week.”可知，问句为现在完成时，主语是you，其谓语结构是：have+动词的过去分词，因此排除C选项；“borrowed”借，是短暂性动词，不能与一段时间连用，排除B选项；“kept”借，延续性动词，可以和一段时间连用。故选A。 14．My parents ________ for fifteen years. A．married B．got married C．have married D．have been married 【答案】D 【详解】句意：我的父母已经结婚十五年了。 考查现在完成时与延续性动词的用法。married结婚，marry的过去式/过去分词；got married结婚，get married的过去式，表短暂性“结婚”动作；have married结婚，marry的现在完成时形式。marry为短暂性动词；have been married已婚，be married的现在完成时形式，be married表延续性“已婚状态”。根据“for fifteen years”可知，此处需与延续性动词的现在完成时连用，have been married符合要求。故选D。 15．—How long ________ your father ________? —Since last month. A．has; been ill B．has; fallen ill C．did; fall ill D．did; be ill 【答案】A 【详解】句意：——你父亲病了多久了？——从上个月开始。 考查现在完成时与延续性动词的用法。be ill生病；fall ill生病。“How long”询问持续时间，需用现在完成时have/has done，且动词需用延续性动词，be ill表示状态，可延续。故选A。 16．—Where is your sister?
