A．Which B．It C．What D．That 【答案】C 【详解】句意：最令我们惊讶的是他说话的方式。 考查主语从句。Which哪一个；It它；What什么，作主语宾语；That无意义，起连接作用。此句为主系表结构，was之前为主语从句；主语从句中，谓语为surprised，因此空处作主语，指“令我们惊讶的内容”。故选C。 4．—________ I will take part in this English contest is still not decided. —You should make up your mind. We don’t have more time. A．If B．Whether C．Which D．What 【答案】B 【详解】句意：——我是否参加这次英语比赛还没有决定。——你应该下定决心。我们没有更多的时间。 考查主语从句连接词。If是否；Whether是否；Which哪个；What什么。根据“is still not decided”可知还没决定是否参加比赛，此处引导主语从句且处于句首，用Whether而不用If。故选B。 5．__________ we will go for a picnic or not depends on the weather.

A．how B．as C．that D．which 【答案】D 【详解】句意：——她喜欢喝茶还是咖啡？——不知道她想喝哪个。 考查主语从句连接词。根据“Does she like to have tea or coffee?”可知，问句给出了两个选择，茶还是咖啡，因此答句用连接代词which引导从句，表示从中挑选哪一个，故选D。 8．It makes no difference ________. A．whether will you come tomorrow B．whether or not will be pass the exam C．if he will come to the meeting or not D．whether he will come to the meeting or not 【答案】D 【详解】句意：他来不来参加会议，没有什么影响。 考查主语从句。根据句子结构可知，it是形式主语，空处的句子是主语从句，应用陈述语序，故排除疑问语序的A项；B项缺少主语，句子不完整，故排除；if，是否，不能和or not连用，故排除C项。故选D。 9．—You won’t be successful ________ you work hard. —I agree. That’s ________ everyone is making an effort to realize their dreams. A．until; why B．unless; because C．unless; why D．until; when 【答案】C 【详解】句意：——你不会成功的，除非你努力工作。——我同意。这就是为什么大家都在努力实现自己的梦想。 考查连词。until直到；unless除非；why 为什么；because因为；when何时。第一空用unless，引导条件状语从句，意思相当于if not，符合两个分句间的逻辑。根据“You won’t be successful...you work hard.”可知，只有努力才会获得成功，这是大家努力实现梦想的原因，所以第二空用why引导表语从句。故选C。 10．Many people ask me why I like Mickey Mouse. That’s ________ he always tries his best to win. A．if B．after C．though D．because 【答案】D 【详解】句意：许多人问我为什么喜欢米老鼠。那是因为他总是尽最大努力去赢。 考查连词辨析。if如果；after在……之后；though尽管；because因为。根据“Many people ask me why I like Mickey Mouse.”可知此处介绍喜欢米老鼠的原因，用because引导表语从句。故选D。 11．Everybody might make mistakes, but the difference is ________ we see the mistake — a learning experience or a failure.

A．that B．if C．whether D．when 【答案】A 【详解】句意：问题是他不听任何人的话。 考查表语从句。that那个（引导表语从句时，不作成分，无实际意义）；if是否；whether是否；when什么时候。根据“The question is...he won’t listen to anyone.”可知，此处表示“他不听任何人的话”就是问题所在，表语从句“he won’t listen to anyone”已表达出完整的意义，此时从句的引导词应用that。故选A。 15．Jack studies hard every day. That’s ________ he always gets good grades in the exam. A．why B．who C．what D．when 【答案】A 【详解】句意：Jack每天都努力学习。这是他总在测验中获得好成绩的原因。 考查表语从句。why为什么；who谁；what什么；when什么时候。That指代“Jack studies hard every day”，分析句子含意可知，努力学习是取得好成绩的原因，应该用why表示原因。故选A。 二、单词拼写 16．It s________ that many people can’t live happily without smart phones. 【答案】(s)eems 【详解】句意：似乎没有智能手机，许多人就不能幸福地生活。根据“It...that many people can’t live happily without smart phones.”和首字母提示可知，现在许多人离不开手机，此处是似乎没了手机，人们就不能幸福地生活，句子为表语从句，空处需填连系动词，即It seems/seemed that...表示“似乎……”，此为事实，时态用一般现在时，seem用“三单”形式seems。故填(s)eems。 17．That’s ____ she wants to be a teacher. 【答案】why 【详解】句意：那就是她想当老师的原因。That’s why…“那是……的原因”，符合语境。故填why。 18．"Every time you eat a sweet, drink green tea."
