You may borrow whichever （book） you like. 所有的书都在这儿, 你愿借哪本就借哪本.// I'll do whatever you ask me to do. 你叫我做什么, 我就做什么.2.that 引导名词性从句时后面接完整的陈述句, that 只起引导名词性从句的作用而不充当该名词性从句中的具体成分；引导宾语从句时that 常可省略, 但引导主语从句、表语从句、同位语从句时that 通常不被省略.例如：She hoped （that） he would arrive on time. 她希望他按时到达.（宾语从句）That she was chosen made us very happy. 她被选中了让我们很开心.（主语从句）I have the belief that I will succeed. 我怀有必胜的信念.（同位语从句）that, what 引导名词性从句的区别在于：that 在其引导的名词性从句中不充当任何成分, 在有的情况下可以省略；what 需要在其引导的名词性从句中充当主语、宾语、表语或者定语, 而且引导名词性从句的what在任何情况下都不能省略.例如：That he will succeed is obvious. 显然, 他会成功.（引导主语从句的that 不在其中充当具体的句子成分）What she told me is not true. 她所告诉我的都不是真的.（what 在其引导的主语从句中作宾语）3.whether 与if 均可以引导表示“是否”之意的名词性从句, 且whether 与if 均不在这种名词性从句中充当具体的句子成分.在引导宾语从句时whether 与if 一般可以互换, 但在引导主语从句、表语从句、同位语从句、介词后的宾语从句、放于句首的宾语从句或者名词性从句中包含or （not）时通常只能用whether 作引导词.注意体会下列例句：I don' t know if/whether I can help you. 我不知道我能否帮助你.（宾语从句）// Whether we can really help you, I don't know yet. 我们是否真的能帮助你, 我还不知道.（位于句首的宾语从句）// The teacher worried about whether he had hurt the girl's feelings. 老师为是否伤害了那女孩的感情而担心.（介词后的宾语从句）// The question is whether they can cooperate with us. 问题是他们能否与我们合作.（表语从句）// The question whether he should come himself or send a substitute must be decided upon. 他该亲自来还是派人替他来, 这个问题必须定下来.（同位语从句）// The little girl asked her father whether she should go to the party or not. 那女孩问她的父亲她应不应该参加这个晚会.（包含or not 的宾语从句）注意：肯定形式的doubt 后面通常接whether/if 引导的宾语从句, 否定形式的doubt后面通常接that 引导的宾语从句, 例如：I doubt whether it's true. 我怀疑它是否是真实的.// I doubt if that was what he wanted. 我怀疑那是否是他所想要的.// I don't doubt that you are honest. 我不怀疑你的诚实.// She never doubted for a moment that she was right. 她对自己是正确的这一点从不怀疑.［考题1］—Could you do me a favor?—It depends on ___ it is. （2006 北京）A. whichB. whicheverC. whatD. whatever［答案］C［解析］下划线处的引导词引导on 后的宾语从句, 并且在该宾语从句中充当表语, 表示疑问句“What is it? （你要我帮的忙是什么?）”的含义.注意：题干中没有用“whatever” 进行强调的必要.［考题2］—I think it's going to be a big problem.—Yes, it could be.—I wonder __ we can do about it. （2002 北京春）A. ifB. howC. whatD. that［答案］C［解析］下划线处的引导词引导wonder 后的宾语从句并且在该宾语从句中充当do 的宾语, if, that 引导名词性从句时都不充当名词性从句中的句子成分, how 引导名词性从句时充当名词性从句中的方式状语, 因此应排除A、B、 D 而选出 C.本题中what we can do about it 可以理解为对应于疑问句“What can we do about it?”的名词性从句, what 引导的这种名词性从句跟其他疑问词形式的引导词所引导的名词性从句的含义相近.［考题 3 ］You can only be sure of _ you have at present: you cannot be sure of something ____ you might get in the future.
