1.解析】答案是B。这里or表示转折，意为“不然”，“否则”。此句可以转换为：If you drink too muchcoffee in the evening you won’t fall asleep.
2.解析】答案是A。“努力学习，你就会赶上别人的。”此句可以转换为：If you study hard you willcatch up with others.注：祈使句在变为if从句后，原祈使句后的and或or必须去掉。
3.解析】本题考查的是宾语从句引导词的选择。连词that在宾语从句中无实际意义，口语中经常省略掉。whom和what应当是充当句子中的宾语，而此句中从句的宾语为discussionAC均不适宜。这里是让对方告诉“明天在哪里开讨论会”，只有时间，没有地点，所以此题的正确答案是D。
4.解析】本题考查了宾语从句的语序及引导词的选用。宾语从句要使用陈述句语序，即“主语+谓语…”的结构，因此首先排除CD两项；who和whose都可以引导宾语从句；根据句意“谁的风筝”，故选B。
5.解析】答案是B。根据宾语从句时态前后应保持一致的原则，首先应排除A，C两项；又根据宾语从句的语序要求陈述句结构，排除D项。注：从句时态的呼应规律为
|
原直接引语中 |
变成的宾语从句中 |
|
一般现在时 |
一般过去时 |
|
现在进行时 |
过去进行时 |
|
现在完成时 |
过去完成时 |
|
一般将来时 |
过去将来时 |
|
一般过去时 |
过去完成时或一般过去 |
6.解析】原句为陈述句，引号内为直接引语，按要求应改成由that引导的宾语从句。根据上面的表格，主句的时态是过去时，从句的谓语动词要变成相应的过去的时态，以保持前后时态的一致。本题答案是George said that he was writing a report and he couldn’t go shoppingwith me.
7.解析】答案是A。原句What’s the matter with Peter?是一个特殊疑问句，变成了由what引导的宾语从句，因此what在句中作主语，the matter作表语，所以语序不变，系动词is不可放到表语the matter之后。故仍应是what’s the matter。类似的结构还有I don’t know what is wrongwith Peter.而不是I don’tknow what wrong is with Peter.
8.解析】此题既考查了宾语从句的时态，又考查了条件状语从句。第一个句子里if引导的是一个宾语从句，因不知“是否要来”，动作尚未发生，从句的谓语动词应用将来时will come才合情理。第二句中的if引导的是一个条件状语从句，意思是“如果他要来的话”。在条件句中应用一般现在时代替将来时。惟有D项才同时符合这两个条件，所以答案为D。
9.解析】按照语法规则我们可以首先确定宾语从句为陈述句语序，便可以排除C、D选项。其次要弄清这里的could不表示过去时态，而是表示一种客气、婉转的语气，所以宾语从句不用过去时态。本题的答案是B。
10.解析】当宾语从句表示的是一个自然现象、科学原理、客观事实时，即使主句是过去时，从句也要用一般现在时。因此本题答案为B。
11.解析】宾语从句中如果是含有or的选择疑问句，应该用whether来连接，而不用if，这里应填whether。注：whether和if均可用来引导宾语从句，意思也相同，一般可互换。但下列情形须用whether，不用if。(1)介词之后：We are talking about whether we will go for a picnic or not.(2)不定式之前：I asked her whether to sit at the front.(3)与or not连用时：I don’t know whether he can speak Japanese or not.
12.解析】当主句的主语为I，we，谓语为think，believe，guess，suppose等词时，其后的宾语从句的否定应该转移到主句上。如：I don’t think she can drive a bus.所以本题的答案为：I don’t believe he can work out the problem by himself.
13.解析】答案是B。在when，as，before，after，as soon as，until等引导的时间状语从句和if引导的条件状语从句中，从句该用一般将来时的时候，需用一般现在时去代替一般将来时。这里的A，C，D三个选项均表示将来，所以不能选。
14.解析】答案是A。因为since引导的时间状语从句在绝大多数情况下时间搭配比较固定，主句是可延续性动词的现在完成时，从句是瞬间性动词的一般过去时，表示动作的起点。但是“It is．．since”句型例外；如:it is almost ten years since we left school.
15&16解析】结果状语从句可以转换成简单句。当that从句是否定式时，可转换成“too…todo”结构，当that从句是肯定式时，可转换成“形容词／副词+enough( for sb ) to do”结构。上面两道题的答案分别为15. too，to 16. enough，to
17.解析】表示“因为……所以……”这种概念时，不可受汉语习惯的影响。要么只用because，构成原因状语从句；要么只用SO，构成并列句。because/as/since不能与so出现在同一句中。
18.解析】though/although不能与but出现在同一句中，但可以用yet。In fact I didn’t understand the question ___was asked in French.A. who B.whose C.which D.what
19.解析】答案是C。“事实上我不懂用法语提出的这个问题。”句中，先行词question指物，故用关系代词which，在定语从句中作主语。
20.解析】答案是A。“我们所需要的是淡水。”句中“that we need”是定语从句，修饰先行词all。all是不定代词，后面一般不用关系代词which修饰，排除C。what不引导定语从句，排除B。D则与句意不符。
