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。 1．The Capital Museum _______ a lot of creative cultural products since it started using digital technology. A．is creating B．was creating C．will create D．has created 【答案】D 【详解】句意：首都博物馆自从开始使用数字技术以来，已经创造了许多创意文化产品。 根据句中时间状语“since it started using digital technology”可知，since引导的时间状语从句通常与现在完成时连用，表示动作从过去某一时刻开始一直持续到现在。is creating为现在进行时，was creating为过去进行时，will create为一般将来时，has created为现在完成时。 2．The number of cars ________ fast in our city in the past ten years. A．increased B．have increased C．has increased D．increase 【答案】C 【详解】句意：在过去十年里，我们城市的汽车数量增长很快。 “in the past ten years”是现在完成时的标志词，排除A（一般过去时）和D（一般现在时）；“the number of+名词复数”作主语时，谓语动词用单数形式，“has increased”符合要求。 3．By the time we arrived, the movie ________ for ten minutes. A．has started B．had started C．has been on D．had been on 【答案】D 【详解】句意：当我们到达的时候，电影已经上映十分钟了。 has started已经开始；had started已经开始；has been on已经上映；had been on已经上映。根据“By the time we arrived”可知，主句动作发生在过去某一时间之前，应用过去完成时（had + 过去分词），结合“for ten minutes”可知，谓语动词需用延续性动词，start是瞬间动词，不能与时间段连用，需变为be on，所以，had been on符合题意。 4．My sister has learned English ________ she was in Grade 7. A．when B．since C．until D．before 【答案】B 【详解】句意：我姐姐从七年级开始学英语。 when当……时；since自从；until直到；before在……之前。根据“has learned”可知，句子是现在完成时，“she was in Grade 7”是一个时间点，应用since。 5．The airline ________ for about 5 months. I have taken the flights three times. A．is open B．has opened C．has been open D．has been opened 【答案】C 【详解】句意：这条航线已经开通大约 5 个月了。我已经乘坐过三次航班了。 句中“for about 5 months”是一段时间状语，要求谓语动词具有延续性。open作动词意为“打开”，是瞬间动词，不能与段时间连用；作形容词意为“开着的、营业的”，表示状态，可延续。has been open表示“一直处于开通状态”，符合语境。 6．—Lisa’s pet dog ________ for a year, but she is still sad. —Let’s go and buy her one. A．died B．is dying C．has died D．has been dead 【答案】D 【详解】句意：——丽莎的宠物狗已经去世一年了，但她仍然很难过。——我们去给她买一只吧。 根据时间状语“for a year”可知，句子应用现在完成时，且谓语动词需能延续。die是短暂性动词，不能与时间段连用，需转换为be dead表示状态。A项为一般过去时；B项为现在进行时；C项虽为现在完成时但动词不可延续；D项为现在完成时且表示状态可延续，符合语境。故选has been dead。 7．Lisa ________ a lot in the past few years. She’s no longer a shy girl. A．changed B．changes C．has changed D．had changed 【答案】C 【详解】句意：丽莎在过去的几年里改变了很多。她不再是一个害羞的女孩了。 根据时间状语“in the past few years”可知，句子应用现在完成时，结构为have/has + done。 8．So far, Chinese scientists ________ great achievements in space and deep-sea research.

A．is B．has been C．has passed 【答案】B 【详解】句意：——共青团员给年轻人树立了好的榜样。你加入共青团多久了？——两年了，我为自己是其中一员而骄傲。 根据答句“For two years.”可知，问句是询问入团持续的时间，应使用现在完成时且强调状态的持续，应填has been。 18．— Look!
