高三英语知识点总结1
look up the dictionary
汉语中的“查字典”，说成英语通常是 look up sth in a dictionary 或 consult [refer to] a dictionary。如：
I refer to the dictionary frequently. 我经常查阅词典。
You can look the word up in the dictionary. 你可以在词典里查这个词。
He often consulted a dictionary when he read the book. 他读这本书时经常查字典。
I looked the word up in the dictionary to refresh my memory of its exact meaning. 我查了词典，以便弄清这个词的准确意思。
I often look up the words I don’t know in the dictionary or on the Internet. 我经常在字典里或网上查我不认识的单词。
“Is that the correct spelling?” “I don’t know—look it up in a dictionary.” “那是正确的拼写吗?”“我不知道——查查词典吧。”
I didn’t know what “loquacious” meant and had to look it up in a dictionary. 我不知道loquacious这个是什么意思，所以只好查了词典。
有不少人认为英语习惯上不能直接说 look up the dictionary, 其实这种表达在英语中也可以用，只是比较少见而已。例如：
I spend more time looking up the dictionary than reading the book. 我读这本书时查字典的时间还多些。——摘自 L. G. Alexander 编《新概念英语》(外研社)
Look up the dictionary and explain the meaning of the italicized words. 查字典然后解释斜体词的意思。——摘自张汉熙编《高级英语》(商务印书馆)

副词的排列顺序：
1) 时间，地点副词，小单位的在前，大单位在后。
2) 方式副词，短的在前，长的在后，并用and或but等连词连接。
Please write slowly and carefully.
3) 多个不同副词排列：程度+地点+方式+时间副词。
注意：副词very 可以修饰形容词，但不能修饰动词。
改错：(错) I very like English.
(对) I like English very much.
注意：副词enough要放在形容词的后面，形容词enough放在名词前后都可。
whatever什么意思 I dont know him well enough.
There is enough food for everyone to eat.
There is food enough for everyone to eat.
Who / whoever, what / whatever等的用法区别
一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为无论什么/无论谁。
It is generally considered unwise to give a child ____ he or she wants.
A. however B. whatever C. whichever D. whenever
指的概念。同时要注意，这里 whatever也不能改用no matter what，因为后者只能引导状语从句。比较下例：
I cant remember at the moment who has said the words. (这里的who表特定的某人)
Where, when, why等连接副词引导的名词性从句
Where, when, why等连接副词也可以引导名词性从句，使用的关键是：这个词必须符合句子的逻辑要求。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why B. when C. that D. where
解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或 where等，的依据便是句子的逻辑含义，及语境。
介词+who(m)引导的宾语从句与介词+ whom引导的定语从句的区别
介词后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。
It was a matter of ____ would take the position.
A. who B. whoever C. whom D. whomever
解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，由于这里引导词在从句中作主语，所以要用主格who(作宾语时自然要用whom)。

疑问代词概说
疑问代词有who(谁，主格)，whom(谁，宾格)，whose(谁的，所有格)，what(什么)和which(哪个，哪些)等。
疑问代词用于特殊疑问句中
疑问代词一般都放在句首，并在句中作为某一句子成分。如：
Who is going to speak to us tomorrow?明天谁来跟我们讲话?(who作主语)
Who told you so?是谁告诉你的?(who作主语)
Whom are you talking about ?你们在说谁?(whom作宾语，但在句首时口语常用who代替whom)
Whose umbrella is this ?这是谁的伞?(whose作定语)
What is that? 那是什么?(what作表语)
What did he say?他说什么?(what作宾语)
Which is yours，the blue pen or the redone?蓝笔和红笔哪一支是你的?(which作主语)
[注一]关于疑问代词的各种用法，可参看77.70-77.72。
[注二]疑问代词who，what，which等后面加单词ever，可强调语气，表达说话人的各种感情。如：
What ever do you want?你到底想要什么?
Who ever is she looking for ?她究竟是在谁?
[注三]which表示在一定范围之内的选择，what则没有这种限制。如：
What do you usually have for lunch?你们午饭通常吃些什么?
Which do you like best?你最喜欢哪一个?
Which of you comrades come from the Northeast? 你们同志们中间谁是东北人?
疑问代词可以引导一个间接疑问句
间接疑问句在句中可用作主语、宾语、表语等。疑问代词本身在间接疑问句中又担任一定的句子成分。如：
Who will be in charge of the work is still not decided.谁将负责这项工作，现在还没有决定。(疑问代词who引导一个主语从句，它本身又在从句中用作主语。)
Do you know what his name is?你知道他叫什么名字吗?(疑问代词what引导一个宾语从句，而它本身又在从句中用作表语。)
[注一] what所引导的名词性从句(即主语从句、宾语从句、表语从句) 有时不是间接疑问句。如：
What he says is quite true.他所讲的话很对。(what相当于that which。它引导一个主语从句，这个从句不是间接疑问句。)
Children do what the nurse tells them to do.保育员让孩子干什么他们就做什么。(what引导一个宾语从句，这个从句也不是间接疑问句。)
[注二] whatever，whoever，whichever等词可引导名词性从句。这些名词性从句也不是间接疑问句。whatever，whoever，whichever也可引导表示让步的状语从句。见15.65和15.72)如：
They eat whatever they can find.他们到什么就吃什么。(whatever引导一个宾语从句，并在从句中作宾语。)
Ive got plenty of books 1eft.Whoever wants an extra copy can get one from me.我还剩下许多书，谁还想再要一本可来拿。(whoever引导一个主语从句，并在从句中作主语。)
