答案解析 一、单项选择（共50小题；每小题1分，满分50分） 1.答案：A。解析：考查宾语从句引导词。固定结构have no doubt that…“毫不怀疑……”，that引导陈述事实的宾语从句，在从句不作成分；what什么，if是否，when何时，均不符合句型。 2.答案：B。解析：考查宾语从句引导词。be sure that…“确信……”，that引出确定的陈述内容；if/whether是否，why为什么，语义不通。 3.答案：C。解析：考查固定句型和形容词作表语。It’s beyond doubt that…“毫无疑问……”；be动词后需要形容词rainy作表语；rain为名词或动词，不能直接放在be后。 4.答案：D。解析：考查宾语从句引导词。be not sure whether…“不确定是否……”，whether表“是否”；never doubt that…“从不怀疑……”，that接确定的事实。 5.答案：B。解析：考查宾语从句引导词。believe后接that引导宾语从句，that无实义只起连接作用；whether/if是否，what什么，不符合句意。 6.答案：B。解析：考查宾语从句时态。从句“太阳从东方升起”是客观真理，无论主句时态，从句用一般现在时；主语the sun是单数，谓语用rises。 7.答案：C。解析：第一空whether…or not为固定搭配，不能使用if；第二空if引导条件状语从句，遵循主将从现，主语we和invite是被动关系，用一般现在时被动are invited。 8.答案：B。解析：考查宾语从句引导词。whether…or not“是否”固定搭配，if不能直接跟or not连用；that无实义，how怎样，不符合语境。 9.答案：B。解析：考查宾语从句。decide后接whether to‑do不定式结构，if不可以直接接不定式；how怎样，that无实义，排除。 10.答案：B。解析：考查宾语从句语序与there be句型。宾语从句必须用陈述语序，排除C；there be句型不能和have混用，排除D；next week表将来，用there is going to be，排除A。 11.答案：A。解析：第一空if引导宾语从句意为“是否”，this evening表将来，用will come；第二空if引导条件状语从句“如果”，主将从现，用一般现在时is。 12.答案：D。解析：第一空whether…or not固定搭配；第二空if引导条件状语从句意为“如果”，whether不能引导条件状语从句。 13.答案：C。解析：doubt用于肯定句，后接whether引导宾语从句；宾语从句要陈述语序，排除D；never doubt that…“从不怀疑……”，that引导确定事实。 14.答案：D。解析：第一空be sure that…“确信……”，that引出确定信息；第二空tell us后接whether引导宾语从句，表“是否”。 15.答案：C。解析：介词about后面表“是否”只能用whether，不能用if；that语义不通。 16.答案：D。解析：if此处引导宾语从句“是否”，根据答句will可知动作表将来，使用will practice，本句不是条件状语从句。 17.答案：C。解析：第一空if引导宾语从句“是否”，表将来用will pass；第二空if引导条件状语从句，主将从现，用一般现在时pass。 18.答案：B。解析：第一空if引导宾语从句“是否”，tonight表将来，用will join；第二空if条件状语从句，主将从现，主语he为三单，用finishes。 19.答案：C。解析：宾语从句使用陈述语序，排除B、D；根据答语可知表达“是否会喜欢它”，用whether引导。 20.答案：C。解析：从句“光比声音传播快”是客观真理，不受主句时态影响，使用一般现在时travels。 21.答案：D。解析：从句“地球绕太阳转动”是客观真理，用一般现在时；主语the earth是单数，谓语用goes。 22.答案：B。解析：主句told是一般过去时，遵循主过从过；the next day是相对于过去的将来，用过去将来时would go。 23.答案：B。解析：主句asked是一般过去时，宾语从句时态倒退；if引导宾语从句表“是否”，will变为would；宾语从句为陈述语序。 24.答案：B。解析：固定句型There is no doubt that…“毫无疑问……”，that引导宾语从句。 25.答案：B。解析：宾语从句要用陈述语序，排除A、C；主句为一般现在时，D选项planned时态逻辑不合理，选B。 26.答案：A。解析：宾语从句用陈述语序，排除B、D；答语回答地点Hainan，故用where提问地点。 27.答案：C。解析：答句指代人，宾语从句陈述语序；who在从句中作宾语，选C。 28.答案：C。解析：whose“谁的”，在从句中作handbag的定语；which哪一个，who谁，what什么，语义不符。

36.答案：B。解析：宾语从句陈述语序，排除C、D；答句回答起火的起因，what作主语询问“什么事物”。 37.答案：C。解析：考查宾语从句简化结构what to do；what作do的宾语；how to do后面必须接宾语；A为疑问语序，错误。 38.答案：C。解析：宾语从句陈述语序，排除A、B；假期尚未到来，表将来，用what Tom will do。 39.答案：C。解析：答句“右边那家24小时营业，可以存钱”，回答“哪一家银行”；where虽然语法通顺，但结合答语细节，which bank更贴合命题意图。 40.答案：D。解析：特殊特例：which is the way to…本身是陈述语序；根据take exercise可知要去sports center运动中心。

48.答案：B。解析：宾语从句陈述语序，排除A、C；警察询问孩子居住地点，where提问地点。 49.答案：A。解析：宾语从句陈述语序，排除B、D；答语To realize our dream表目的，why提问原因。 50.答案：A。解析：I don’t think引导宾语从句，否定前移，反义疑问句看从句；从句she will arrive，前否后肯，用will she。 二、用所给单词的适当形式填空（共25小题；每小题1分，满分25分） 1.答案：would have。解析：主句said为一般过去时，主过从过；next week相对于said是过去视角下的将来，用过去将来时would have。 2.答案：will come。解析：主句I hope一般现在时，主现从不限；some day表将来，从句用一般将来时will come。 3.答案：has seen。解析：if引导宾语从句，before是现在完成时标志；主语he三单，has seen。 4.答案：shut。解析：just now“刚才”为一般过去时；shut过去式仍为shut。 5.答案：will rain；doesn’t rain。解析：第一个if引导宾语从句表将来，用will rain；第二个if引导条件状语从句，主将从现，主语it三单，用doesn’t rain。
