高考英语语法介词考点
介词是一种用来表示词与词、词与句之间的关系的虚词，在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类，短语或从句作它的宾语。介词和它的宾语构成介词词组，在句中作状语、表语、定语或宾语补足语。介词可分为时间介词、地点介词、方式介词、原因介词和其他介词。
①Nothing in the world could live without air or water.(状语)
②This machine is in good condition.(表语)
③Where is the key to my bike?(定语)
④She always thinks herself above others.〔宾补〕

[考点一]考查with/without复合结构
介词with/without+名词/代词+形容词/副词/介词短语/动词不定式/分词〔分词可以是现在分词，也可以是过去分词〕在句中表状态或说明背景情况，常作伴随、方式、原因、条件等状语。
With all the things she needed bought, she went home happily.
Possibly this person died without anyone knowing where the coins were hidden.
单项填空
①It was a pity that the great writer died _____ his works unfinished.
A. for          B. with            C. from      D. of
解析：选B。考查with复合结构。works 与unfinish之间为动宾关系，所以用过去分词表示被动。如果名词或代词与后面的动词是主谓关系，则用现在分词表示主动。
[考点二]考查工具、手段、方式介词
〔1〕by, in, on三词都可表示旅行的方式
①不涉与交通工具的名词时用by，名词前不加冠词。如by sea, by water, by land, by rail, by air等。
②涉与交通工具的名词时用by，名词须用单数形式，前面不加冠词或任何修饰语。如by bike, by taxi, by plane, by ship/boat, by train, by spaceship等。
③当旅行方式涉与确定特指的交通工具时，用on或in，名词前加冠词、物主代词、指示代词等修饰语。如travel to New York in this plane，leave on an early train，go to school on my bike等。
注意：步行、骑马、骑骆驼均用on。如on foot，on horseback，on a horse，on the camel。
〔2〕with, by, in三词均意为“用〞，表示行为的工具、手段或方式。
①with用于有形的工具或身体某些器官之前，其后的名词多被冠词、物主代词等修饰。
They are digging with a pick/spade.
We see with our eyes, hear with our ears, and walk with our legs.
②by, in, on, over, through等介词多用于无形的工具或方式手段之前。如by hand, in ink, on the telephone, over the radio, through the telescope等。
注意：①使用语言、原料、材料时，用in表示，如in English/Japanese；in blue ink等。
②表达“用……方法/式〞时，所用介词有：in this/that/the same way，by means of，by this/that means，with this/that method等。
[考点三]考查of+抽象名词的用法
“of+抽象名词method形容词〞的用法与形容词相同，在句中可作表语、定语、补语。
of+great/much +抽象名词=very+名词的形容词形式
of+no+抽象名词=not+名词的形容词形式
It is of great value.=It is very valuable.
It is of no use.=It is useless.
The camel is of great help to the Arab.
＝The camel is very helpful to the Arab.
[考点四]考查表示程度的介词by, to, beyond
by 表示“增加了……〞；to表示“增加到……〞；beyond表示“X围, 限度超出〞。
This new model of car is so expensive that it is beyond the reach of those with average incomes.
单项填空
②Sorry, Madam. You’d better come tomorrow because it’s ______ the visiting hours.
A. during            B. at            C. beyond      D. before
解析：选C。考查介词的用法。句意为：对不起，女士，你最好明天来，因为已经过了开放时间了。beyond〔时间〕晚于，迟于。
[考点五]考查介词but的固定搭配
have no choice but to do只得做某事； can’t help but do不得不做……； can’t but do不得不只能； can’t choose but do只得做某事； but for要不是……。
I have no choice but to accept his conditions.
There was no taxi that day, I couldn’t choose but stay there for
another night.
[考点六]考查to one’s+情感类名词
to 与情感类名词连用，表示“某人因某事的发生而唤起其内心的某种情感〞。常见的结构有：to＋one’s＋delight/surprise/horror/sorrow/joy/regret＝to the delight/surprise/horror/sorrow/joy/regret of sb.。这种结构表示结果，用作状语，通常置
于句首，也可置于句中或句末。若要加强该结构的语气，有两种方式：①在名词前加great, deep等形容词修饰；②在整个短语前加副词greatly, much等修饰。
To his disappointment, he failed again.
[考点七]考查名词与to构成的固定搭配
key, approach, solution, answer, entrance, visit, attitude等与to构成固定搭配：the key/approach/solution/answer/entrance/visit/。
