Step1 一,介词
1、介词的分类与语法功能
(1)介词是虚词,不能单独作句子成分,必须与名词、代词(或相当于名词的其他词类、短语或从句等)构成介词短语,在句中充当一个成分。介词分为:简单介词,如at、in、for等;合成介词,如within、inside、onto、througout等;短语介词,如according to、out of、because of、by means of、in spite of、instead of等。双重介词,如from behind / above / under、until after等。分词介词,如considering、including、judging(from / by) 等。
常见的介词宾语:名词、代词、动名词、从句、不定式等。如:
①It is going to rain this afternoon according to the weather forecast.
②He quarrelled with her yesterday.
③He succeeded in passing the final exam.
④I’m still thinking of how I can fulfil the task ahead of time.
⑤The professor will give us a talk on how to study English well.
(2)介词短语在句中可作表语、定语、状语和宾补等。如:
①This machine is in good condition.(表语)
②Where is the key to my bike?(定语)
③Nothing in the world could live without air or water.(状语)
④She always thinks herself above others.(宾补)
2、介词搭配
(1)“动词+介词”搭配:注意特定搭配与同一介词与多个动词搭配意义不同的情况。
①rob sb. of sth. / clear the road of snow(“夺去、除去”意义的动词与of 连用)
②supply us with food / fill the glass with wine(“供给”意义的动词与with连用)
③make a desk of wood / make bread from flour / make the material into
a coat(“制作、制造”意义与of、from、into连用)
④介词 + the + 部位与动词的关系(=动词 + sb.’s + 部位,可换用)
strike him on the head(“击,拍,碰,摸”意义与on连用)
catch him by the arm(“抓,拉,拿,扯”意义与by连用)
hit the boy in the face(“肚,胸,眼,脸”等人体前部与in连用)
⑤prevent(stop, keep)sb. from doing sth.(“阻止,禁止”意义与from 连用)
⑥persuade(advise, warn)sb. into doing sth.(“说服,建议”意义与into连用)
⑦buy sb. for sth.(leave、get、win、gain、lose等“得失”意义与for 连用)
⑧tell sth.to sb.(show、teach、sing、write、read等“告知”意义与
to连用)
⑨give sth. to sb.(give、allow、promise、pass、hand等“授予”意义与to连用)
注意:⑦⑧⑨可换成buy sb.sth.双宾结构。
⑩say to sb.(suggest、explain、apologize、murmur、whisper与“对象”连用必须用to)不可说suggest sb.sth.。

3、核心介词用法归纳与辨析
(1)表示时间的介词in的用法如下。
表示在某一较长时间内,如世纪、年、月、季、周等一般用介词in,
如:in the 1990s, in the year, in January, in(the) winter / summer / fall / spring, in the first week of May。
还可以用时段名词组成固定短语或词组。如:in a while, in no time, in the daytime, in a short while, in time, in the morning (afternoon, evening)。但要注意:
①at night / at noon, in the day(在白天),in the night(大夜间)。
②in five days(weeks, months, years)中in意思是“在……以后”。
③in和during表一段时间内两词可互用。如:in the night, during the night, in the war, during the war。但略有区别:当接表示“活动”的抽象名词时多用during,接“活动”的动名词及短语时用in。如:
(2)在具体的某一天或某天上午、晚上、前夕,常用on。
