(2)if不能替换whether的5种情况：a.正式文体中，句中有or not时I wonder whether it is big enough or not.我想知道它是否足够大。注意：在口语中“if...or not”可接受，但连写的“if or not”是错误的。b.引导主语、表语、同位语从句时：Whether it is true(or not)remains a question.它是不是真的还是一个问题。c.作介词宾语时I haven't settled the question of whether I'll go back home.我还没决定是否要回家。d.在不定式前，与不定式组成词组She hasn't decided whether to go or not.她还没有决定去还是不去。e.作discu等词的宾语We discued whether we should close the shop.我们讨论是否该关闭那家商店。
(3)if还有“假如”之意，引导条件状语从句，而此时的条件状语从句，又具体分为两种情况：表示真实条件和表示假设条件，详解如下：
a.表示真实条件。“如果” If he told you that, he was lying.如果他是那样对你说的，他就是在撒谎。If it rains tomorrow, we will stay at home.如果明天下雨，我们就不出去。
注意：if条件句要求用一般时表示将来，不用will表示将来，只有在表示“愿意”或“不愿意”时，if后才可以跟will或won't。If you won't come, I'll go alone.如果你不愿意来，我就一个人去。
b.表示假设条件，“假如”，用虚拟语气与现在事实相反 If I were you, I would help her.我要是你的话，我就会帮助她。
与过去事实相反 If I had not mied the train, I would have got home by now.假如我没误了火车，现在早该到家了。与将来事实相反 If any one should call, please let me know.万一有人打电话来，请告诉我一声。

(1)which既可引导定语从句，又可连接名词性从句；而what不可引导定语从句。
(2)which，what同为名词性从句的连接代词时，都可在所连接的名词性从句中充当主语或宾语，其区别在意思上。what强调“内容”，而which强调从已知的、确定的范围中做出选择。This river, which flows through London, is called the Thames.(which引导非限制性定语从句)这条流经伦敦的河，叫泰晤士河。What book are you going to read? 你要读什么书?
Which book are you going to read, this one or that one? 你要读哪一本书，这本还是那本? 注意：以下句子中常用what。(1)What season do you like best? 你最喜欢什么季节?(2)What day is today? 今天是星期几?(3)What's the date today? 今天是几号? 联想：somewhat adv.稍微，有点whatever pron.无论什么；凡是„„的东西

I hope we'll be friends and come to understand each other.我希望我们成为朋友并逐渐相互理解。He came to realize that he was wrong.他开始认识到自己错了。辨析：get，go，turn与come
get强调造成事件的施动者发挥的作用或变化的结果。go常常表示不顾施动者的愿望而发生的变化，多用于表示恶化的情况。turn经常表示从某种状态向其对立状态转化的自然现象。come

since时间从句中，不论用短暂动词、延续动词还是状态动词的一般过去时，通常都表示从动作或状态的完成或结束时算起，因此这种since从句应理解为“自从该动作结束以来”。如：Great changes have taken place here since he left.自从他离开以来，这里发生了巨大的变化。
提示：(1)从句中使用延续性动词时，常容易误解。(2)如果要表示从句中的动作或状态延续至今，该动词须用现在完成时，有时也可以用一般过去时，但这时需要在since前加ever，强调与现在的联系。如：I haven't heard from him since he lived(was)in Beijing.自从他离开北京，我没有收到过他的来信。How long is it since you smoked? 你戒烟多久了(或你多长时间没抽烟了)?I have known her since I have lived here(或ever since I lived here / since I lived here).从我住到这儿以来，我就认识她。
