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。 32．Jane wants to know. Can we finish the work on time?（合并宾语从句） 【答案】Jane wants to know if we can finish the work on time./Jane wants to know whether we can finish the work on time. 【详解】句意：简想知道。我们能按时完成这项工作吗？合并为宾语从句，此处表示想知道是否能完成工作，用if/whether“是否”引导宾语从句，宾语从句用陈述语序，情态动词位于主语后面。故填Jane wants to know if/whether we can finish the work on time. 33．“Are you enjoying your new jobs?” Jessie asked Carter and Harry. （改为含有宾语从句的复合句） Jessie asked Carter and Harry they enjoying their new jobs. 【答案】 if/whether were 【详解】句意：“你喜欢你的新工作吗？”杰西问卡特和哈利。原来的句子是一般疑问句，宾语从句连接词需要用if或whether；宾语从句的主句是一般过去时，所以从句用过去进行时，即were enjoying。故填if/whether；were。 34．我们想知道是否能在明年看到电影《哪吒3》。 We wonder Ne Zha 3 next year. 【答案】 if/whether we can see 【详解】根据中英文对照可知，空格处为“是否”if/whether，以及“我们能看到”we can see。根据“We wonder”可知，此处为宾语从句，从句应用陈述语序，引导词为if/whether。故填if/whether；we；can；see。 35．I wonder if I should book the tickets for tomorrow’s concert.(改为简单句) I wonder book the tickets for tomorrow’s concert. 【答案】 whether to 【详解】句意：我想知道我是否应该预订明天音乐会的门票。原句是if引导的宾语从句，改为简单句时，“whether+动词不定式”结构可以和if引导的宾语从句进行转换，都表示“是否做某事”。故填whether；to。 36．“Can you be kind enough to help me out?” Joan asked Mike.  (改为宾语从句) Joan asked Mike he be kind enough to help her out. 【答案】 if/whether could 【详解】句意：“你能帮帮我吗？”琼问迈克。直接引语为一般疑问句时，改为宾语从句用if/whether连接，并改为陈述句语序；由于主句Joan asked Mike时态为一般过去时，从句也要改为相应的过去时态，所以情态动词can变为could。故填if/whether；could。 37．许多学生想知道是否还有更好的方法来解这道数学题。 Many students there is a better way to work out the math problem. 【答案】 wonder if/whether 【详解】中英文对照可知，此处缺少中文“想知道是否”的翻译，其中“想知道”在英文中对应“wonder”，意为“感到好奇或想知道某事”，句子应用一般现在时，主语为Many students，谓语用动词原形；“是否”在英文中可以用“if”或“whether”来表示，两者在此上下文中均可，用于引导一个表示疑问或不确定性的宾语从句。故填wonder；if/whether。 38．Is there a restroom nearby? Could you please tell me? (合并为一句) Could you please tell me is a restroom nearby? 【答案】 if/whether there 【详解】句意：请问附近有洗手间吗？ 你能告诉我吗？这是将两个句子合并为一个宾语从句的问题。原句是一般疑问句“Is there a restroom nearby?”，在合并为宾语从句时需使用引导词if或whether，引导词后使用陈述语序，即“there is...”。故填if/whether；there。 39．我很高兴我赢了。 I’m so . 【答案】happy that I won 【详解】分析句子可知，空处需要翻译的是“高兴我赢了”，happy意为“高兴的”，形容词作表语，that引导宾语从句，I“我”，作主语，事情发生在过去，应该用一般过去时，此处用动词过去式won，意为“赢”。故填happy that I won。 40．我认为四月是泰国最热的月份。 I April is the hottest month in Thailand. 【答案】 believe that 【详解】I believe that...“我认为……”，that后接宾语从句；根据语境可知，此句表达现在的看法，应用一般现在时，主语为I，谓语动词believe用原形。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 $$
