2. 时态
含宾语从句的复合句，主、从句谓语动词的时态呼应，包括以下三点内容：
1）如果主句的谓语动词是一般现在时，从句的谓语动词可根据需要，选用相应的任何时态。如：①I don’t know when he will come back. 我不知道他将何时回来。
②He tells me that his sister came back yesterday. 他告诉我他姐姐昨天回来了。
2）如果主句的谓语动词是过去时，宾语从句的谓语动词只可根据需要，选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。如：
①The children didn't know who he was. 孩子们不知道他是谁。
②He asked his father how it happened. 他问他父亲这件事是如何发生的。
3）如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句用什么时态，从句时态都用一般现在时。
如：The teacher said that the earth goes round the sun. 老师说地球绕着太阳转。

宾语从句：
考点1：引导词的选用。
(1). 陈述句的引导词用that，常可省略。一般疑问句的引导词用if/ whether(是否)。
考点2：语序 (宾语从句中从句要用陈述句语序，即从句中的第1助动词在主语之后）
考点3：时态（主句从句在时态上要一致）
30．D

考查宾语从句引导词。how怎样；when什么时候；why为什么；where在哪里；whether 是否，宾语从句引导词；if引导条件状语从句；从文字的表层意思推断，句子的表达是“查明受害者是否在被找到的地方被杀的”；空格1是宾语从句的引导词，意为“是否”，所以填whether；空格2引导地点状语从句，“在被杀的地方”，所以填where；故选D。
31．B
——乒乓球比赛真让人兴奋。对方的队伍真的很强大。——是的，但是我从不怀疑我们队会赢。
考查宾语从句。if如果；that无意义；whether是否；why为什么。根据“...our team will win.”可知此句用that引导，无意义，不作成分。故选B。
32．A
下列哪个不是定语从句
考查定语从句。在复合句中，修饰名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的有关系代词who、whom、whose、which、that等和关系副词where、when、why等，关系代词和关系副词在定语从句中充当句子成分。A项The police have confirmed that the victim was a computer engineer中，没有被修饰的名词或代词，that在此引导宾语从句；B项A detective is someone who looks for clues to something important中先行词是someone，who是引导定语从句的关系代词，所以B项是定语从句；C项Yuan Longping is one of the greatest people that have ever lived中，先行词是people，that是引导定语从句的关系代词，所以C项是定语从句；D项The journey would take only 20 minutes in spacecraft that travel at the speed of light中，先行词是spacecraft，that是引导定语从句的关系代词，所以D项是定语从句，故选A。
33．D

考查句子结构。Ninan is no longer the city that it used to be.尼南不再是过去的那个城市了。该句是that引导的定语从句；Bamboo grows well where there is plenty of rain.雨水多的地方竹子长得好。该句是where引导的状语从句；I always remember the days in the country when I look at the photos.当我看着这些照片时，我总是记得在乡下的日子。该句是when引导的时间状语从句；I am sure that he is a helpful person as we have known each other for years.我相信他是一个很有帮助的人，因为我们已经认识多年了。该句是as引导的原因状语从句，但是主句中又包含了that引导的宾语从句。故选D。
34．B

35．C
我不怀疑他能完成这项任务，但我怀疑他是否愿意做这件事。连词if引导宾语从句，意思是“是否”，当主句是一般现在时态时，从句可为需要的任意时态。根据语义可知前半句是that引导的宾语从句，从句部分无疑问；后半句有疑问，意为“是否”，有if引导的宾语从句。故选C。
36．B

考查宾语从句和名词。doubt怀疑，是一个动词，后面常跟宾语从句，当用于肯定句时，宾语从句用whether引导；当用于否定句时，用that引导。句中never是否定意思，故宾语从句用that引导，排除C和D。第二个空考查短语show interest in…对…感兴趣，interest是名词。故选B。

试题分析：句意: 探索者坚持认为他的建议很有价值。insist on后跟v-ing形式作宾语；insist that后跟宾语从句，空后有系表结构，故第一空只能选that。be of value=valuable很有价值。根据题意选B。
考点：考查宾语从句引导词和介词短语。
40．D
试题分析：毫无疑问艾米丽将是新年晚会的女主持。在复合句中，如果主句中有no、all、最高级、序数词等，从句引导词常用that。故选D。
考点：考查从句中引导词的用法。
41．whether/if it is worth taking/accepting his advice/whether/if his advice is worth taking/accepting
根据英汉对照可知，空格处填“是否值得采纳他的建议”，也可表达为“他的建议是否值得采纳”，whether/if“是否”，be worth doing sth.“值得做某事”，take/accept his advice“采纳他的建议”。由语境可知，从句时态为一般现在时，陈述现在情况。故填whether/if it is worth taking/accepting his advice/whether/if his advice is worth taking/accepting。
42．if the match will be covered live/whether the match will be covered live
根据中英文对照可知，英文句子缺少“比赛是否会现场直播”，分析英文句子成分可知，此部分充当宾语从句，可以用if或whether“是否”引导。从句主语“比赛”和“报道”之间是被动关系，且根据语境可知，从句用一般将来时态，因此从句采用一般将来时态的被动语态，结构是will be+动词的过去分词。从句谓语动词可用cover“报道”，cover的过去分词是covered。副词live“现场直播”修饰动词covered。故答案为：if/whether the match will be covered live。
43． whether/if he should
“不知道”也表示“是否”，译为whether/if，主语“The man”用he代替，“应该”用should表示。故填whether/if；he；should。
44． whether/if he could
根据中英文对照，可知缺少“他能否”，是否“whether/if”，他“he”，能“can”，根据“Tom didn’t know...”可知，此处为宾语从句，主句时态为一般过去时，从句也应使用过去的某种时态，故此处can应用其过去式could。故填whether/if；he；could。
45． whether/if if
whether/if“是否”，引导宾语从句，if“如果”，引导条件状语从句。故填whether/if；if。
46． if/whether she would like
分析题干可知，句子为含宾语从句的复合句；对比中英文可知，空处缺少“是否原意”；if/whether“是否”，用来引导宾语从句；Rebecca为女子名，人称代词用she代替； would like to do sth.“愿意做某事”，动词短语。故填if/whether；she；would；like。
47．whether there is/if there is
根据中英文对照可知，空处缺少了“是否有”，用whether或if引导宾语从句，there be“有”，主语bank是单数，句子时态为一般现在时，be动词用is。故填whether/if there is。
48． if/whether he could help
结合中英文，时态为过去时，所缺表达为：是否他能帮忙；if/whether“是否”，he“他”；could“能”，情态动词后接动词help“帮忙”原形。故填if/whether；he；could；help。
49． if/whether on
根据句子结构可知，动词wondered后为宾语从句，空处缺少连接词，又因主句存在疑问并且从句不缺少任何成分，空处表示“是否”，可用whether或if作连接词；put on weight表示“增加体重”，因此第二个空填介词on。故填if/whether；on。
50． if/whether we’ll
根据中英文对照，可知英文句中缺少“是否”和“我们（将）”部分；分析句子，结合中文句意，可知动词know后接宾语从句，根据“是否”，可知引导词为if/whether；根据“next month”，可知从句时态为一般将来时，主语是we，故第二空为we’ll。故填if/whether；we’ll。
