A．before B．as if C．as soon as 【答案】C 【详解】句意：——今天早上你赶上早班车了吗？——是的。我一上车，公交车就开动了。 考查连词辨析。before表示“在……之前”；as if表示“似乎”；as soon as表示“一……就”。根据“The bus started to move…I got on it.”可知，表示“一上车，公交车就开动了”，符合语境。故选C。 二、完成句子(本大题共10小题，每小题2分，共20分) 41．My brother often reads storybooks. He has free time. (when) （用括号内的词连接两个句子） ___________________________________________________________________ 【答案】My brother often reads storybooks when he has free time. 【详解】句意：我哥哥经常读故事书。他有空闲时间。括号内提示用when连接两个句子；“He has free time”是“My brother often reads storybooks”的时间条件——当有空闲时间时他读故事书。将第二句作为when引导的时间状语从句置于主句之后，主句保持不变，从句中主语he指代My brother，时态为一般现在时。故填My brother often reads storybooks when he has free time. 42．当火灾发生时，不要使用电梯。 Don’t use the lift ________ a fire ________. 【答案】 when happens 【详解】第一空需要填入引导时间状语从句的连词，对应“当……时”，when符合句意；第二空需要填入从句的谓语动词，对应“发生happen”，主句是祈使句，从句陈述客观事实或规则用一般现在时，从句主语是a fire（单数），因此动词happen需变为第三人称单数形式happens。 43．在孩子们打雪仗时，米莉摔倒了。 Millie ______________________________________ . 【答案】fell down while children were having a snowball fight 【详解】根据中文意思可知本题考查动词短语fall down“摔倒”和have a snowball fight“打雪仗”及单词while“当……时”。由语境可知事情已经发生，时态为过去相应的时态，while引导时间状语从句，此处应用过去进行时，主句用一般过去时，故填fell down while children were having a snowball fight。 44．康康在上音乐课的时候，达伦在爬山。 Darren was climbing the mountain while Kangkang ________ ________ _________ ________ ________. 【答案】 was having a music class 【详解】while表示对比，根据“Darren was climbing the mountain”可知，句子用过去进行时，即was/were+V-ing。主语是Kangkang，be动词用was。have a music class表示“上音乐课”。故填was；having；a；music；class。 45．He signed the last letter. He passed away. （连成一句话） He signed the last letter ________ he passed away. 【答案】before 【详解】句意：他在最后一封信上签了名。他去世了。两句连成一句，可表示为“ 去世前他在最后一封信上签了名”。before，连词，表示“在……之前”，引导时间状语从句。故填before。 46．在接受这个挑战前请三思。 Please ________________ the challenge. 【答案】think twice before you take on/think twice before taking on 【详解】根据汉语提示可知，该句为祈使句肯定形式，分析句子结构，before you do sth/before doing sth.“在做某事之前”；think twice“再三考虑；重新考虑”；take on the challenge“接受挑战”。故填think twice before you take on/think twice before taking on。 47．一下飞机，我们就先去了延安革命纪念馆。 ________________ we got off the plane, we went to the Yan’an Revolutionary Memorial Hall first. 【答案】As soon as 【详解】中文“一……就……”表示两个动作紧接着发生，对应英文短语as soon as，它引导时间状语从句，首字母需要大写。故填As soon as。 48．海伦打算一完成工作就和你谈谈。 Helen is going to talk with you ________ ________ ________ she ________ her work. 【答案】 as soon as finishes 【详解】根据中英文对照可知，此处缺“一……就……”和“完成”，“一……就……”翻译成“as soon as”，引导时间状语从句；“完成”翻译成finish，在as soon as引导的时间状语从句中，主句用一般将来时，从句要用一般现在时表将来；从句主语she是第三人称单数，所以finish要用第三人称单数形式finishes。故填as；soon；as；finishes。 49．汤姆直到雨停了才离开。 Tom ________ leave ________ the rain stopped. 【答案】 didn’t until 【详解】分析中英文提示可知，句子缺少“直到……才”的表达，英文是not…until…，根据后面的“stopped”可知时态是一般过去时，leave是实义动词，对其否定借助助动词did。故填didn’t；until。 50．My father came back last night. Then my mother went to bed. (合并为一句) My mother ________ ________ to bed ________ my father came back last night. 【答案】 didn’t go until 【详解】句意：昨晚我爸爸回来了。然后我妈妈去睡觉了。合并为一句需要加连接词，句意变为“昨晚直到我爸爸回来，我妈妈才去睡觉。”原句为一般过去时，合并后句子时态不变；not...until表示“直到……才”，谓语动词went是实义动词，前面需要借助助动词did，与not缩写为didn’t，went变为原形go。故填didn’t；go；until。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $
