You work hard, so you will make it. A．if B．that C．what D．how 【答案】A 【详解】句意：——我不知道这次我是否能通过英语考试。——别担心。你学习努力，所以你会成功的。 考查宾语从句引导词辨析。if 是否；that 无实义（仅引导陈述句）；what什么；how怎样。根据答句“Don’t worry. You work hard, so you will make it.”可知，说话人表达的是对“能否通过考试”的担忧，因此从句中缺少表示“是否”含义的引导词。故选A。 2．I’m not sure ______ we should go hiking tomorrow; the weather forecast says it might rain. A．when B．where C．whether D．why 【答案】C 【详解】句意：我不确定我们明天是否应该去徒步旅行；天气预报说明天可能会下雨。 考查宾语从句引导词辨析。when何时；where何地；whether是否；why为什么。根据后半句“the weather forecast says it might rain.”可知，说话人对“明天是否去”这件事不确定，因此从句应表达“是否”的含义。故选C。 3．I ________ if the plan will succeed. A．doubt B．consider C．think D．need 【答案】A 【详解】句意：我怀疑这个计划是否会成功。 考查动词辨析。doubt怀疑；consider考虑；think认为；need需要。根据从句“if the plan will succeed”中的if表示“是否”，且主句表达对计划成功的不确定或怀疑，doubt常与if/whether连用表示“怀疑……是否……”，符合句意。故选A。 4．—Alice, I wonder ________ you won the tug-of-war (拔河比赛) yesterday. —Yeah! We pulled together and made it in the end. A．though B．whether C．unless D．until 【答案】B 【详解】句意：——爱丽丝，我想知道你们昨天是否赢了拔河比赛。——是的！我们齐心协力，最终成功了。 考查宾语从句引导词辨析。though尽管；whether是否；unless除非；until直到。根据答语“Yeah! We pulled together and made it in the end.”可知，问句是在询问“是否”赢得了比赛，且wonder后常接whether/if引导的宾语从句表示“想知道是否……”。故选B。 5．It depends on ______ we have enough time, not on ______ the weather is good. A．whether; whether B．whether; if C．if; whether D．if; if 【答案】A 【详解】句意：这取决于我们是否有足够的时间，而不取决于天气是否好。 考查连词辨析。whether是否；if是否。在介词后引导宾语从句时，只能用whether，不能用if。第一个空位于介词on后，只能用whether；第二个空也在介词on后，同样需用whether。故选A。 6．—Jenny, do you know if your mother ________ back tomorrow? —Sorry, I don’t know. If she ________ home, I’ll tell her to call you. A．comes; gets B．comes; gets to C．will come; gets D．will come; gets to 【答案】C 【详解】句意：——珍妮，你知道你妈妈明天是否会回来吗？——对不起，我不知道。如果她到家，我会让她给你打电话的。 考查if引导的宾语从句和条件状语从句的时态。第一空，根据语境可知，此处是询问是否明天回来，所以用一般将来时will come；第二空，根据“If she...home, I’ll tell her to call you.”可知，这是一个条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时表将来，且home为地点副词，其前不用介词，所以第二空应填gets。故选C。 7．—What did Peter say to you just now, Kate? —He asked me ________. A．if I have read the book Little Women B．whether will I believe in him C．if I had joined the music club D．whether I will believe in him 【答案】C 【详解】句意：——彼得刚才对你说什么了，凯特？——他问我是否加入了音乐俱乐部。 考查宾语从句的语序和时态。根据“He asked me...”可知，本句为宾语从句，宾语从句需用陈述语序，排除B；主句“He asked”为一般过去时，从句时态也应用过去的某个时态，排除A和D (现在完成时和一般将来时)。故选C。 8．I wonder if the scientist ________ to our school tomorrow. If he ________, we will be very excited. A．comes; comes B．will come; comes C．comes; will come D．will come; will come 【答案】B 【详解】句意：我想知道那位科学家明天是否会来我们学校。如果他来，我们会非常兴奋。 考查条件状语从句和宾语从句的时态。根据“I wonder if the scientist…”可知，第一空是宾语从句，时间状语“tomorrow”应用一般将来时“will come”；根据“If he…we will be very excited.”可知，第二空是if引导的条件状语从句，遵循“主将从现”原则，从句用一般现在时表示将来，应该使用comes。故选B。 9．—Can you tell me if it ________ tomorrow? —I’m not sure, I will go swimming if it ________ tomorrow. A．will rain; doesn’t rain B．will rain; won’t C．rains; will rain D．rains; won’t 【答案】A 【详解】句意：——你能告诉我明天是否会下雨吗？——我不确定，如果明天不下雨我就去游泳。 考查动词时态。第一个空，“if”引导的是宾语从句，意思是“是否”，根据“tomorrow”可知，此句描述的是将来的事情，所以要用一般将来时“will rain”；第二个空，“if”引导的是条件状语从句，意思是“如果”，在条件状语从句中，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时，所以这里应该用一般现在时的否定形式“doesn’t rain”。故选A。 10．He isn’t sure if it ________ next Sunday. If it ________, he won’t go camping. A．will rain; rainy B．rains; rains C．will rain; rains D．rain, rain 【答案】C 【详解】句意：他不确定下周日是否会下雨。如果下雨，他就不去露营了。 考查动词时态和条件状语从句。第一个空，根据“next Sunday”可知，此处是if引导的宾语从句，从句的动作还没有发生，所以用一般将来时，其结构为“will+动词原形”，即will rain；第二个空，根据语境可知，此处是if引导的条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时表将来，从句主语it是第三人称单数，所以谓语动词用三单形式rains。综上，第一个空填will rain，第二个空填rains。故选C。 11．It seems that he hasn’t decided ________ to give up the competition or not. A．that B．how C．if D．whether 【答案】D 【详解】句意：他似乎还没决定是否放弃比赛。 考查宾语从句。that引导宾语从句时只起连接作用，无实际词义；how怎样；if是否；whether是否。根据“he hasn’t decided… to give up the competition or not”，可知他还没决定是否放弃比赛，whether… or not“是否”，是固定搭配。故选D。 12．—Would you like to go for a picnic in the mountains? —I’d like to, but I’m not sure ________ the weather will be fine on that day. A．when B．if C．what D．how 【答案】B 【详解】句意：——你想去山里野餐吗？——我想去，但我不确定那天天气是否好。 考查宾语从句的引导词。when什么时候；if是否；what什么；how怎样。根据“I’d like to, but I’m not sure…the weather will be fine on that day”可知，此处是不确定天气“是否”好，需用表示“是否”的连接词引导宾语从句。if 在此处意为“是否”，符合语境。故选B。 13．—I want to know if it ________ tomorrow. —Me, too. If it ________, we will have to stay at home. A．will rain; rains B．rains; rains C．will rain; will rain D．rains; will rain 【答案】A 【详解】句意：——我想知道明天是否会下雨。——我也是。如果明天下雨，我们将不得不待在家里。 考查if从句的时态用法。will rain将会下雨，一般将来时；rains下雨，一般现在时。在第一个句子中，if引导宾语从句，根据时间状语“tomorrow”可知，从句需用一般将来时；在第二个句子中，if引导条件状语从句，表示将来条件时，从句需用一般现在时代替将来时，主句用一般将来时。故选A。 14．—________ did you say to our English teacher? —I asked her ________ I had passed the exam or not. A．How; if B．What; whether C．What; if D．How; whether 【答案】B 【详解】句意：——你对我们英语老师说了什么？——我问她我是否通过了考试。 考查疑问词和宾语从句引导词辨析。How怎样；What什么；if是否；whether是否。根据“... did you say to our English teacher?”可知，缺少say的宾语，用what；根据“... I had passed the exam or not.”可知，此处是whether...or not“是否”的固定搭配。故选B。 15．Please let us know ________ you need help. A．but B．or C．if D．because 【答案】C 【详解】句意：请让我们知道你是否需要帮助。 考查连词辨析。but但是；or或者；if是否；because因为。根据“Please let us know...you need help.”可知，此处是询问对方是否需要帮助，应用if引导宾语从句。故选C。 16．—Do you know ________ Jane will come to our party? —I’m not sure. She said she was busy, but she might try to make it. A．that B．if C．what D．who 【答案】B 【详解】句意：——你知道简是否会来参加我们的派对吗？——我不确定，她说她很忙，但她可能会尽力来参加。 考查if引导的宾语从句。that引导宾语从句时无实际词义；if是否；what什么；who谁。根据“I’m not sure. She said she was busy, but she might try to make it.”可知，此处问对方“简是否会来参加派对”，“if”符合语境。故选B。 17．—Would you like to see the new movie 731 tomorrow? —Yes, of course. But I am not sure ________ Tony will go. A．why B．what C．that D．if 【答案】D 【详解】句意：——你明天想去看新电影《731》吗？——当然，但我不确定托尼是否会去。 考查宾语从句。why为什么；what什么；that那；if是否。根据句意，空格处需填入表示“是否”的引导词，表达不确定托尼是否会去。故选D。 18．Could you please tell me ________ go on the spring outing to Chongming Island? A．that we would B．if we will C．if we would D．that we will 【答案】B 【详解】句意：你能告诉我我们是否会去崇明岛春游吗？ 考查宾语从句的引导词和时态。that we would我们会去，过去将来时；if we will我们是否会去，一般将来时；if we would我们是否会去，过去将来时；that we will我们会去，一般将来时。根据句中的“Could you please tell me…”可知，此处是宾语从句，礼貌询问未来计划，需用if表“是否”，主句中could表示委婉的语气，与时态无关，从句问的是将来的事情，应用一般将来时，故选B。 19．They want to know ______ they will have the meeting tomorrow. A．whether B．what C．that D．which 【答案】A 【详解】句意：他们想知道明天是否会开会。   考查连词辨析。whether是否；what什么；that那个；which哪一个。根据句意，此处需要表示“是否”的连词引导宾语从句。故选A。 20．We haven’t decided ________ we will go on a picnic this weekend. A．until B．whether C．since D．unless 【答案】B 【详解】句意：我们还没有决定这个周末是否去野餐。 考查宾语从句引导词。until直到；whether是否；since因为，自从；unless除非。根据“We haven’t decided ...”可知，此处用whether引导宾语从句，表示“是否”，强调对选择的不确定性。故选B。 21．—I wonder if John ________ next year’s talent show. —I have no idea. But I think if he ________ his class project, he will. A．joins; finishes B．will join in; will finish C．takes part in; finishes D．will take part in; finishes 【答案】D 【详解】句意：——我想知道约翰是否会参加明年的才艺表演。——我不知道。但我想如果他完成了他的班级项目，他会的。 考查时态。第一处是if引导的宾语从句，根据“next year’s talent show”可知，用一般将来时；第二处是if引导的条件状语从句，需满足“主将从现”原则，主语是“he”，动词用三单。故选D。 22．—Do you know if he ________ the job offer? —Unless he ________ a higher salary, I am sure he won’t. A．will receive; accepts B．will accept; receives C．receives; will accept D．accepts; receives 【答案】B 【详解】句意：——你知道他是否会接受这个工作吗？——除非他得到更高的薪水，我确定他不会。 考查时态和动词辨析。receive收到；accept接受。根据“Do you know if he … the job offer?”可知，此句是if引导的宾语从句，此处说的是不知道是否会接受，用一般将来时，因此第一个空填will accept；再由“Unless he…a higher salary,”可知，此句是Unless条件状语从句，该从句描述的是除非他得到更高的薪水，这是一个条件，通常使用一般现在时来表示将来。所以，这里应该使用一般现在时“receives”。故选B。 23．Let me know ________ or not you can come. A．whether B．if C．which D．that 【答案】A 【详解】句意：让我知道你是否能来。 考查宾语从句。whether是否；if是否；which哪一个；that引导宾语从句无实义。根据“or not”可知，此处只能用whether引导宾语从句。故选A。 24．It doesn’t matter ________ you turn right or left at the crossing. Both roads lead to the art museum. A．whenever B．unless C．though D．whether 【答案】D 【详解】句意：无论你在十字路口向右转还是向左转都没有关系。两条路都通向艺术博物馆。 考查连词辨析。whenever无论何时；unless除非；though尽管；whether是否。根据“It doesn’t matter…you turn right or left at the crossing.”可知，此处指无论你在十字路口向右转还是向左转都没有关系，whether…or…“无论……还是……”，固定搭配；空处应用whether引导宾语从句。故选D。 25．—Nelly, do you know if Eric ________ the trip with us tomorrow? —He will go with us if he ________ free. A．takes; is B．will take; will be C．will take; is D．takes; will be 【答案】C 【详解】句意：——Nelly，你知不知道明天Eric是否会和我们一起去郊游？——如果他有空，他会和我们一起去的。 考查if引导宾语从句和条件状语从句。根据“do you know if Eric...the trip with us tomorrow”可知，此处的if“是否”引导宾语从句，结合tomorrow，此时从句用一般将来时will do，排除选项A和D；根据“He will go with us if he...free.”可知，此处的if“如果”引导条件状语从句，时态遵从“主将从现”，从句用一般现在时，主语是he，从句的谓语动词用三单形式，is符合语境。故选C。 二、完成句子 26．我什么也看不见，也不知道周围还有没有其他人。 I see anything , and I didn’t know anyone else was around me. 【答案】 couldn’t at all if/whether 【详解】根据“didn’t know”可知，时态为一般过去时，“什么也看不见”对应否定表达“couldn’t see anything at all”，“couldn’t”表示“不能”，“not...at all”是固定短语，表示“根本不、一点也不”；“不知道周围有没有其他人” 中，“有没有”在宾语从句中用“if/whether”引导（表 “是否”）。故填couldn’t；at；all；if/whether。 27．我不知道史密斯先生是在家还是在他的办公室。 I don’t know Mr. Smith is at home at his office. 【答案】 whether or 【详解】根据中英文对照可知，空格处表示“是……还是……”的含义；“I don’t know”后接宾语从句，此处需用“whether...or...”表示“是否……还是……”，来引导宾语从句，连接“在家”和“在办公室”这两个选择项。故填whether；or。 28．I don’t know whether he will come or not. (改为同义句) I don’t know he will come. 【答案】if 【详解】句意：我不知道他是否会来。原句中的“whether…or not”可以替换为“if”来表达相同含义，两者都表示“是否”的意思。故填if。 29．Does he go to Central Park? Could you tell me? (改为宾语从句) Could you tell me he to Central Park? 【答案】 if/whether goes 【详解】句意：他去中央公园吗？你能告诉我吗？原句为一般疑问句，改为宾语从句时，需要使用if/whether引导，表示“是否”；原句时态为一般现在时，宾语从句主语为he，动词应使用第三人称单数形式goes。故填if/whether；goes。 30．“Can you tell me about the power of curiosity?” My English teacher asks me.（改为宾语从句） My English teacher asks me the power of curiosity or not. 【答案】whether I can tell her about 【详解】句意：“你能告诉我好奇心的力量吗？”我的英语老师问我。此处可改为“我的英语老师问我是否可以告诉她好奇心的力量。”，直接引语是一般疑问句，且根据“or not”可知改为宾语从句时，引导词是whether；且宾语从句是陈述语序，把主语you改为I，me改为her；根据“asks”可知主句是一般现在时，故此处从句用一般现在时，情态动词can放主语之后，tell her about“告诉她关于……”。故填whether I can tell her about。 31．“Do you like playing football?” Tom asked me. (改为宾语从句) Tom asked me I playing football. 【答案】 if/whether liked 【详解】句意：“你喜欢踢足球吗？”汤姆问我。原句“Do you like playing football?”是一般疑问句，改为宾语从句时，用if/whether“是否”，引导宾语从句，根据“asked”可知，主句是过去时，从句也应用一般过去时，谓语动词用过去式liked。故填if/whether；liked。 32．我不知道他是否会来参加我的聚会。 I don’t know he will come to my party . 【答案】 whether or not 【详解】“whether…or not”是固定搭配，意为“是否”。故填whether；or ；not。 33．“Did you enjoy your trip to London?” Aunt Lily asked us.（改为间接引语） Aunt Lily asked us we our trip to London. 【答案】 if/whether enjoyed 【详解】句意：“你去伦敦玩得愉快吗？”莉莉阿姨问我们。原句可表示“莉莉阿姨问我们是否享受了伦敦之旅。”，一般疑问句（如Did you…?）改为间接引语时，需用if或whether引导，表示“是否”；主句动词“asked”是过去式，从句时态应保持一致。原句“did enjoy”是一般过去时，在间接引语中可改为enjoyed（过去式）。故填if/whether；enjoyed。 34．Judy is wondering. Does Mike surf the Internet every day? (将两句并成一句) Judy is wondering Mike the Internet every day. 【答案】 if/whether surfs 【详解】句意：朱迪在想。迈克每天都上网吗？要求合并句子，合并后，“Does Mike surf the Internet every day?”需作为宾语从句嵌入“Judy is wondering.”中，充当“is wondering”的宾语；“Does Mike surf the Internet every day?”为一般疑问句，转换为宾语从句时，需用if或whether“是否”引导，且宾语从句必须用陈述语序，而非疑问语序，因此需去掉助动词“does”；“every day”表示习惯性动作，从句应用一般现在时，且主语“Mike”为第三人称单数，谓语动词“surf”应用其三单形式surfs。故填if/whether；surfs。 35．“Will the toba run dry soon?” Shabanu worried. (改为间接引语)   【答案】Shabanu worried if the toba would run dry soon./Shabanu worried whether the toba would run dry soon. 【详解】句意：“多巴很快就会干涸吗？”Shabanu担心的说。直接引语改为间接引语，可以改为宾语从句，根据“Shabanu worried”可知，宾语从句的时态遵循“主过从必过”。从句时态用过去将来时，结构为would do。根据“Will the toba run dry soon?”可知，此处想知道多巴是否很快就会干涸，用if或whether引导宾语从句，从句的语序为陈述句语序，主语为the toba，后接would do结构，即would run dry soon。故填Shabanu worried if the toba would run dry soon./Shabanu worried whether the toba would run dry soon. 36．“Will we have an Art Festival in May?” Jason wanted to know.
