参考答案：
1．B
考查动词时态。第一空所在句子是宾语从句，主句是一般现在时态，所以从句可根据需要选择时态，时间状语是tomorrow，所以用一般将来时态；第二空所在句子是时间状语从句，根据“主将从现”原则，此空应用一般现在时态，故选B。
2．D
第一空，if引导的宾语从句表示一般将来时，故用will go。第二空when引导的时间状语从句用一般现在时表示一般将来时，故此处为comes,故选D。
3．D
will 将；won’t 是will not 的缩写；and 和，表示并列；but 但是，表示转折；until直到……时候。根据句意可知本句考查的是not…until句型，表示直到……时候才……。故选D。
4．A
考查连词。even if即使；if如果；so that为了；unless除非；根据句意可知，此处表达的是即使没有成功，也会支持对方，应用even if引导让步状语从句，故选A。
5．B
考查there be句型和if引导的条件状语从句。第一处是there be句型，不与have连用，排除AD；第二处是if引导的条件状语从句，需满足“主将从现”原则。故选B。
6．D
7．D
after在……之后；if如果；because因为；unless除非；根据句意可知是unless引导的的条件状语从句；故选D。
8．A
第一个句子是if引导的宾语从句，主句是一般现在时，从句时态根据句意确定，本句中是问明天是否能来，所以用将来时；第二个句子是if引导的是条件状语从句，遵循主将从现的规则，所有从句应该用一般现在时，从句主语是he，故用comes；故答案选A。
9．B
但是没有人知道周末是否会下雨。第一句中的连词if意为“如果”，用来引导条件状语从句，从句用一般现在时表示将来，故用is fine；第二句中的if意为“是否”，引导宾语从句，根据句意从句用一般将来时will rain。故选B。
考点：考查条件状语从句的用法和宾语从句的用法。
10．D
试题分析：if如果在宾语从句中，表示是否的意思，他的时态要根据自己本身来决定，；而在if 引导的条件状语从句中，如果主句为将来时，从句用一般现在时代替将来时，本题第一空属于宾语从句，而后一句为条件状语从句，故选C。根据句意：我不知道他是否明天回来，如果他来，我将告诉他这件事。根据句意故选D
11．B
考查连词辨析。if如果；unless除非；since自从；that那个。根据“You are sure to fail the exam”及“you study hard”可知，除非努力学习，否则考试就不会及格，用unless引导条件状语从句， 12．A
考查连词辨析。while当……的时候，表时间；though尽管，表让步；because因为，表原因；unless除非，表条件。本句是时间状语从句，根据句意结构，可知选A。
13．D
考查连词辨析。if如果；unless除非，如果不；when当……时候；although虽然，尽管。根据句意可知，空前“It was great”与空后“we had a terrible time”是转折关系，这里应用although引导让步状语从句。故选D。
14．A
试题分析：until直到；if是否，如果；so 因此；because因为。句意：直到我们看了NBA的篮球比赛后，我们才对林书豪——一个来自美国火箭队的篮球运动员有所了解。固定搭配not……until……直到……才，本节中little表示否定含义，故选A。
15．A
考查连词。although尽管，虽然；because因为；if如果；since自从。根据“she is in poor health”可知表达让步“虽然张桂梅身体健康状况很差”，用连词“although”引导让步状语从句。故选A。
16．C
考查连词的辨析。A.because“因为”；B.unless“除非”；C.though“尽管”；D.after“在……之后”。故选C。
17．C
考查连词。A.when当……时候， B.while与……同时，C.until 直到……, D.if如果。 “not…until…”是“直到……才……”，其它选项不符合题意。故选C。
18．A
A.尽管（引导让步状语从句）；B.因为（引导原因状语从句）；C.除非（引导条件状语从句）；D.然而，但是（后加逗号）。根据句意可知，空前和空后之间表示让步，用although，故选A。
19．C
A. If 如果，引导条件状语从句；B. Since 由于，引导原因状语从句；C. Although 尽管，虽然，引导让步状语从句；D. Because 因为，引导原因状语从句。根据句意，故选C。
20．A
当主句是一般将来时态时，if引导的条件状语从句用一般现在时表示将来，就是我们常说的“主将从现”，此句中的it为第三人称单数形式，助动词要用doesn’t，故答案选A。
21．Though he got up early, he missed the train.或He missed the train though he got up early.
though“虽然，尽管”，引导让步状语从句。改写后句意为“虽然他起得很早，但没赶上火车。”，从句部分是though he got up early，位于主句前后均可。故填Though he got up early, he missed the train./He missed the train though he got up early.
22．Although he was tired, he won the game.
Though he was tired, he won the game.
He won the game although he was tired.
He won the game though he was tired.
Although he won the game, he was tired.
Though he won the game, he was tired.
He was tired although he won the game.
He was tired though he won the game
用although/though引导让步状语从句，he won the game作为句子的主句，变成Although/Though he was tired, he won the game./He won the game although/though he was tired.，同时he was tired也可以作为主句，he won the game作从句，变成Although/Though he won the game, he was tired./He was tired although/though he won the game.，故填Although/Though he was tired, he won the game./He won the game although/though he was tired./Although/Though he won the game, he was tired./He was tired although/though he won the game.
23． If you
分析句子可知，“如果你不马上告诉他真相”是“他会生气”的条件，所以应用if引导条件状语从句，主语应该用第二人称you“你”。故填If；you。
24． will if
此处两句合并后可以用if引导条件状语从句来连接。if条件句遵循“主将从现”的原则，主句用一般将来时：will+动词原形。故填will；if。
25． aren’t more
此题要求改为条件状语从句，时态遵循“主将从现”原则，结合题干可知，表示为“如果你不更小心，你会犯更多的错误”。be careful“小心”，主语是you，be动词用are，其否定式为aren’t；“更小心”more careful。故填aren’t；more。
26． If hurry
原句也表示“如果不快点，我们就会迟到”，用if引导条件状语从句，don’t后用动词原形。故填If；hurry。
27． If you wear won’t
考查两个简单句合并为含有if引导的条件状语从句的复合句。根据“Don’t wear your jeans to the party”可知，如果你穿牛仔裤去参加派对的话，老师不会让你进去，应用if引导条件状语从句，引导词if位于句首，首字母要大写。主语为you，遵循“主将从现”原则，从句采用一般现在时，谓语动词用原形wear；主句采用一般将来时，will的否定式为won’t。故填If；you；wear；won’t。
28． Unless won’t
“unless”译为“如果不”，转换成“如果你不努力学习，你就不会成功”。“unless”引导条件状语从句，遵循主将从现的原则，从句引导词用“unless”，注意首字母大写，后面主句用将来时，注意否定形式，应该是“won’t”，故填Unless；won’t。
29． If be
该句if从句为“如果你来参加聚会，我会很高兴的”；if“如果”，引导条件状语从句，句首首字母大写；“will”后接动词原形，此处用be与“happy”构成系表结构。故填If；be。
30． If don’t
如果我们不快点，就赶不上早班车了。根据题干，可知要求改写句子，句意不变，原句中的意思是“快点，否则我们就赶不上早班车了”，相当于“如果我们不快点，就赶不上早班车了”。if引导条件状语从句，用一般现在时表将来．动词是实义动词，we后用助动词don’t，故答案为（1）If（2）don’t。
