A．whether B．when C．who D．where 【答案】A 【详解】句意：那个男孩从自行车上摔下来，他正在拍X光片，以查看他的手臂是否骨折。 考查whether引导宾语从句。whether是否；when何时；who谁；where哪里。根据“The boy fell off his bike and he’s taking an X-ray to see...his arm is broken or not.”可知，此处是说查看手臂是否有骨折，在表达“是否”含义时，只有whether可以与or not连用，whether...or not为常用搭配，意为“是否”，符合语境。故选A。 2．Mark asked ________ there were any peanuts in the food. A．if B．what C．when 【答案】A 【详解】句意：Mark问食物中是否有花生。 考查宾语从句的引导词辨析。if是否；what什么；when何时。根据句意，Mark询问的是“是否有花生”，表示疑问，需用if或whether引导宾语从句。故选A。 3． I don’t know ______ or not he will come. A．if B．whether C．that D．when 【答案】B 【详解】句意：我不知道他是否会来。 考查宾语从句引导词。if是否；whether是否，常与or not连用；that引导宾语从句时，无实际含义；when什么时候。根据句意，此处意为“是否”；根据空格后的“or not”可知，此处应使用“whether”引导宾语从句，“if”通常不与“or not”连用。故选B。 4． He asked me ______ I had seen the film. A．that B．if C．what D．where 【答案】B 【详解】句意：他问我是否看过那部电影。 考查宾语从句引导词辨析。that（无实义，仅起连接作用）；if是否；what什么；where哪里。主句“He asked me”表示询问，从句“I had seen the film”是一个完整的句子，且句意需要表达“是否看过”，因此应选用表示“是否”的引导词。故选B。 5．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。 6．—David is wondering ________ in China. —No. Chinese usually shake hands with a lady as a greeting. A．what he can do to greet a lady B．why he can’t greet a lady by kissing a lady C．whether he can greet a lady by kissing her hand 【答案】C 【详解】句意：——David想知道在中国是否可以亲吻女士的手来问候。——不可以。中国人通常与女士握手以示问候。 考查宾语从句。what he can do to greet a lady他怎么能跟女士打招呼呢；why he can’t greet a lady by kissing a lady为什么他不能通过亲吻女士来问候女士呢；whether he can greet a lady by kissing her hand他是否能通过亲吻女士的手来问候她。根据“No. Chinese usually shake hands with a lady as a greeting.”可知，问的是是否可以亲吻女士的手来问候。选项C符合语境。故选C。 7．I wonder ________ July is the hottest time in Harbin. A．when B．that C．if 【答案】C 【详解】句意：我想知道七月是不是哈尔滨最热的时候。 考查连词辨析。when什么时候；that引导宾语从句无意义；if是否。根据“I wonder…July is the hottest time in Harbin.”可知，此处表示想知道七月是否是哈尔滨最热的时候，应该用if引导宾语从句。故选C。 8．—I’m worried about________ I can get a high mark in the exam. —Take it easy. You’re sure to get a high mark because you are good at English. A．if B．whether C．unless 【答案】B 【详解】句意：——我担心我是否能在考试中取得高分。——放轻松。你一定能取得高分，因为你擅长英语。 考查连词辨析。if是否；whether是否；unless除非。根据“I’m worried about...I can get a high mark in the exam.”可知，担心自己是否能够在考试中取得高分。因为空前是介词about，此处只能用whether引导宾语从句。故选B。 9．I wonder ________ you would like to go fishing with us tomorrow. A．that B．what C．if D．how 【答案】C 【详解】句意：我想知道你明天是否愿意和我们一起去钓鱼。 考查宾语从句的连接词。that引导宾语从句，无实义；what什么；if是否；how如何。根据“you would like to go fishing with us tomorrow”可知，此处指你是否愿意明天和我们一起去钓鱼，if符合题意。故选C。 10．We don’t know ________ or not the book is suitable for children.

A．that B．if C．whether D．where 【答案】A 【详解】句意：他告诉我他第二天会去北京。 考查宾语从句的引导词。that无实义，仅起连接作用；if是否；whether是否；where哪里。由于从句“he would go to Beijing the next day”是一个完整的陈述句，不缺成分，且不需要表达“是否”或“哪里”的含义，因此应使用无实义的连接词that来引导宾语从句。故选A。 14．— Are you sure ________? — Yes, of course. A．if she has a sister B．whether we will do it C．that he can do it on his own D．When they arrived 【答案】C 【详解】句意：——你确定他能独自完成这件事吗？——是的，当然。 考查宾语从句。if she has a sister她是否有一个姐姐；whether we will do it我们是否将做这件事；that he can do it on his own他能独自完成这件事；When they arrived他们什么时候到达的。根据“Are you sure...”以及“Yes, of course.”可知，此处是在确认某件事情，且答句为肯定回答，所以从句应该是陈述句语序的句子，that引导宾语从句无实际意义，只起连接作用，符合语境。故选C。 15．—We never doubt ________ Millie can deal with the problems by herself. —That’s true. I agree with you. A．that B．if C．how D．whether 【答案】A 【详解】句意：——我们从不怀疑米莉能自己处理这些问题。——这是真的。我同意你的看法。 考查词汇辨析。that引导从句，无实义；if如果；how如何；whether是否。根据“We never doubt”可知，该句是否定句，doubt在否定句中，接that引导的宾语从句；在肯定句中，接if/whether引导的宾语从句。故选A。 16．I know ________ I promised to take you out to dinner. But I must finish my work first. A．that B．whether C．what 【答案】A 【详解】句意：我知道我答应过带你出去吃晚餐。但我必须先完成我的工作。 考查宾语从句连接词。that引导宾语从句时，在句中不作任何成分，只起连接作用；whether是否，常与or not连用；what什么，在从句中作主语、宾语等成分。本句中宾语从句“I promised to take you out to dinner”是一个完整的句子，不缺任何成分，所以用that引导。故选A。 17．—Do you think Jack has the ability to win the race? —I never doubt ________ win the race. A．whether he will B．whether will he C．that he will D．that will he 【答案】C 【详解】句意：——你觉得Jack有能力赢得这场赛跑吗？——我从不怀疑他会赢得比赛。 考查宾语从句。宾语从句的语序为陈述句，选项B和D是疑问语序，排除选项B和D，再根据“I never doubt...win the race.”可知，我从不怀疑他会赢，此处用that引导宾语从句符合语境。故选C。 18．Mother says _____________ she won’t be free tomorrow. A．if B．who C．whether D．that 【答案】D 【详解】句意：妈妈说她明天没空。 考查宾语从句的连接词。if是否；who谁；whether是否；that引导宾语从句时不作成分。根据“Mother says…she won’t be free tomorrow.”可知，本句宾语从句是陈述句，表示妈妈说的内容，用that引导宾语从句。故选D。 19．My father always tells me ________ practice makes perfect. A．that B．which C．how D．whether 【答案】A 【详解】句意：我父亲总是告诉我熟能生巧。 考查宾语从句。that无意义，只作引导词，在从句中不作句子成分，有时可省略；which哪一个；how怎样；whether是否。根据句意“我父亲总是告诉我熟能生巧”及语境可知，应选that引导宾语从句。故选A。 20．—I’ve worked much harder than before, but I’m still behind others. —It takes time.

A．that; that B．if; that C．that; if 【答案】C 【详解】句意：我知道她能做好它，但是我不确定她是否愿意做它。 考查宾语从句。第一个从句不缺成分，意义完整，后接that引导的宾语从句；第二个空“I’m not sure”后面一般接whether或if引导的宾语从句。故选C。 22．The teacher says ________ she will leave a message on the headmaster’s desk.

A．if she has a sister B．that he can do it on his own C．whether we will do it D．when they arrived 【答案】B 【详解】句意：——你确定他能自己做吗？——是的，当然。 考查宾语从句。be sure+that从句，表“确定……”，be not sure+if/whether/wh-从句，表“不确定……”。故选B。 24．Are you sure ________ Mr. Li will come to your birthday party?

(改为宾语从句) She asked a post office near there. 【答案】 if/whether there was 【详解】句意：她问附近是否有邮局。原句是一般疑问句“Is there a post office near here?”，改为宾语从句时应用引导词if或whether表示“是否”连接主句和从句； 从句语序要变为陈述语序，即there was； 主句谓语动词“asked”是一般过去时，从句时态要相应变为一般过去时，“is”变为“was”。 故填if/whether；there；was。 33．“Is the boy from France?” he asked me.(改为宾语从句) He asked me the boy from France. 【答案】 whether/if was 【详解】句意：“那个男孩来自法国吗?”他问我。根据括号内的要求可知，要改为宾语从句。当宾语从句的主句时态是一般过去时，从句的时态也要用一般过去时，原句中的is应改为was；一般疑问句转换成宾语从句时，连接词要用whether/if表示“是否”。故填whether/if；was。 34．比利想知道六月是不是游览澳门的好时机。 Billy June is a good time to visit Macao. 【答案】 wonders if/whether 【详解】对照中英文可知，缺少“想知道”和“是不是”。此句为宾语从句，根据“June is a good time to visit Macao”可知，主句用一般现在时，表示现在的状态。“想知道”用wonder，主语为“Billy”，wonder要用三单形式的wonders作主句的谓语；“是不是”用if或whether，引导宾语从句。故填wonders；if/whether。 35．“Do you have fun at the amusement park?” he asked me. (改为含有宾语从句的复合句) He asked I fun at the amusement park. 【答案】 whether/if had 【详解】句意：“你在游乐园玩得开心吗？”他问我。原句为一般疑问句，改为宾语从句时，需用whether或if引导，表示“是否”；主句为一般过去时，从句也需用过去时态，原句一般现在时需改为一般过去时，谓语动词have需用过去式had。故填whether/if；had。 36．杰克想知道我们外出之前雨是否会停。 Jack the rain will stop before we go out. 【答案】 wonders if/whether 【详解】根据中英文对照可知，缺少“想知道”和“是否”。wonder“想知道”，是动词，由语境可知此处时态为一般现在时，而主语Jack为第三人称单数，所以此处应用其第三人称单数形式；if/whether“是否”，是连词，引导宾语从句，故填wonders；if/whether。 37．比尔想知道他们明年是否还会吃粽子。 Bill they’ll have zongzi again next year. 【答案】 wonders if/whether 【详解】根据中英文提示可知，缺少“想知道”和“是否”的表达。“想知道”用动词wonder，主语Bill是第三人称单数，句子描述常态想法，时态为一般现在时，故wonder需变为wonders；“是否”在宾语从句中用if或whether，均符合语境。故填wonders；if/whether。 38．全世界人们都想知道他们是否能在六个月后安全回来。 People all over the world wonder to Earth safely in six months. 【答案】 if/whether they can return 【详解】中英对照可知，空处意为“他们是否能回来”，if/whether“是否”，引导宾语从句；they“他们”，can“能够”，后加动词原形；return“返回”；故填if/whether；they；can；return。 39．“I will learn English well,” Tom said. (改为宾语从句) Tom said learn English well. 【答案】 he would 【详解】句意：“我会学好英语的。”汤姆说道。将直接引语改为宾语从句，用that引导，可以省略，直接引语中的主语 “I”指代Tom，在宾语从句中需改为he“他”；主句动词“said”是过去时，因此从句的将来时“will”需改为过去将来时，填would。故填he；would。 40．我一直相信工作越努力，我就会越幸运。 I always the harder I work, the luckier I will be. 【答案】 believe that 【详解】根据中英文对照可知，此处是that引导的宾语从句。由“always”可知，时态是一般现在时，I believe that+从句，表示“我相信……”，符合语境。故填believe；that。 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 $ Unit 5 Looking into nature 宾语从句（1） （时间：40分钟，满分：100分） 一、单项选择(本大题共30小题，每小题2分，共60分) 1．The boy fell off his bike and he’s taking an X-ray to see ________ his arm is broken or not.
