How soon 多久以后，对将来的时间状语提问；B. How long多长时间，多长，询问时间段或物体的长度；C. How far多远，询问两地距离；D. How much多少，询问量的多少，后跟不可数名词。根据答语“- About 10 minutes ride by bus”可知，问句是提问路程，故选C。22D解析：D【详解】句意：你多久检查一次机油？一大约每5000公里。考查特殊疑问词。how far多远；how long多长；how much多少；how often多久一次；根据回答“About every 5,000 km.”可知，此处问的是多久检查一次，提问频率用how often，故选D。23B解析：B【详解】句意：我期待着电影春天之路。这部电影什么时候上映？直到2020年8月28日才首映。考查疑问词辨析和until用法。when什么时候，表时间；how long多长，问一段时间；until直到，和not连用表示“直到才”，引导时间状语从句。根据回答“the 28th August, 2020”是问电影什么时候上映，when符合句意；结合语境，“它直到2020年8月28日才会首次上映”，即it wont be first shown until the 28th August, 2020.，可知答句是“notuntil”结构，故选B。24A解析：A【详解】句意：蒂米，你多久去看一次你的祖父母？一周一次。考查特殊疑问句。how often多长时间一次；how long多长；how fast多快；how many多少。根据“Once a week”可知一周一次，是表示频率，特殊疑问句用how often来提问。故选A。十、选择题25C解析：C【详解】句意：谁得到了一等奖？Millie得到了。结果刚刚宣布。考查一般过去时的被动语态。announce宣布；分析句子可知，主语“The result”和谓语“announce”之间是被动关系，用被动语态；根据“just now”可知用一般过去时，故用一般过去时的被动语态，结构是：was/were + done，主语是“The result”，be动词用was。故选C。十一、选择题26A解析：A【解析】【详解】考查现在进行时表将来的用法。句意：我要去机场赶下午6点的航班。 请在10分钟内把文件发给我。由题意可知，动作还没发生，所以要用将来时。表位移的瞬间动词可以使用现在进行时表将来。故选A项。27A解析：A【解析】试题分析：考查动词时态。句意：社交媒体，像微信，正在改变当今时代的交流方式。根据nowadays可知，用现在进行时态，media是复数形式，故选A。考点：考查动词时态28C解析：C【解析】试题解析：句意：这里连续不断的吵闹声要把我逼疯了！冷静点。抱怨也没用。根据谈话内容可知：使用现在进行时。故选C。考点：现在进行时及其被动式29C解析：C【解析】试题分析：考查时态。句意：-你为什么选择去西北地区做志愿服务？-通过我的努力，我正在努力改善那里孩子们的生活。过去进行时用来指过去的某个时刻正在发生的事情，根据第一句中的Why do you.可知，这里不用过去的时态，排除A、D；现在完成时表示发生在过去的事情对现在造成的结果，参加志愿服务这件事并未结束，因此不用现在完成时，故选C。考点：考查时态30C解析：C【详解】句意：我能和布朗先生通电话吗？很抱歉，他现在正在办公室召开重要的会议。考查现在进行时。根据语境及“at the moment”可知，打来电话的时候，布朗先生正在开会，时态用现在进行时，结构为am/is/are doing。又因为主语为He，单数，be动词用is。故选C。31A解析：A【详解】句意：请原谅我。我真得要走了。我的孩子们在学校等我。考查动词时态。由“I really need to go now. My childrenfor me at school”可知，因为孩子们正在学校等我，所以我真得要走，故本句为现在进行时态。故选A。十二、选择题32B解析：B【详解】句意：这次小心点，否则你会再犯同样的错误。考查连词辨析。and和，表并列；or否则，用于连接两个并列的句子；so所以，表结果；but但是，表转折。根据前后句子的关系，可知设空处表示“否则”的意思，故选B。十三、选择题33B解析：B【详解】句意：你知道昨晚这个时候她在做什么吗？抱歉，我不知道。考查宾语从句。know后加宾语从句，引导词+陈述句语序，排除C、D选项，主句是一般现在时，从句时态不受限制，结合表达的是过去正在进行的动作，故用过去进行时was/were+doing，故选B。34D解析：D【详解】句意：你能告诉我哪里可以快速买到食物吗？当然。我建议你去水城餐厅。考查宾语从句。此处是宾语从句，用陈述语序，排除AC；根据答语“I suggest Water City Restaurant.”可知，此处指地点，故选D。35C解析：C【详解】句意：-朱蒂，你能告诉我你在哪里买的书包吗？-哦，是的。我在网上的一家商店买的。考查宾语从句。宾语从句要用陈述语序，根据回答I bought it in a store on the Internet.的时态是过去式结合语境可知从句时态要用过去式，书包已经买完了。A和B是疑问句语序，排除，D是将来时排除，结合句意和语境可知选C。十四、选择题36C解析：C【详解】句意：你应该多做，少说。事实胜于雄辩。考查习语。What you do isnt important.你所做的并不重要；What you do is as important as you say.你所做的和你所说的一样重要；What you do is more important than what you say.你所做的比你所说的更重要；What you do is less important than you say.你所做的不如你所说的重要。根据“Actions speak louder than words.”可知，做得比说得更重要。故选C。37D解析：D【详解】句意：Ben，你需要面对恐惧，克服恐惧。那是对的。有
