初中英語語法總結(jié)之介詞解析

　　介詞是一種虛詞，它在句中的作用卻非常重要。它用來表明名詞與句中其他詞的關(guān)系，不能單獨(dú)使用。常考點(diǎn)包括一些固定搭配和一些近義詞。下面是小編給大家?guī)淼某踔杏⒄Z語法總結(jié)之介詞解析，希望能夠幫助到大家!

　　常用介詞解析及用法比較：

　　at,on和in：這三個(gè)介詞在試卷中的出現(xiàn)頻率極高。對(duì)于它們的的分辨只要記住一句話就可以了。at表示點(diǎn)，on表示線，in表示面。什么意思呢?也就是說它們表達(dá)的范圍逐漸增大。at six o'clock, at noon, at the age of sixteen等用at表示時(shí)刻或時(shí)間的點(diǎn)以及年齡。on具體到一周中的各天,日期及某特定的一天早上,下午,晚上：on Saturday，on July 1st，on my birthday，on the morning of July 16th，on a spring afternoon。in表達(dá)的范圍更大一些。與世紀(jì)、年代、季節(jié)、月份以及早上、上午、晚上等連用。如：in the seventh century，in 1950's ,in 2000, in the morning等。

　　for,since：for表示多長時(shí)間。since后接時(shí)間起點(diǎn),其終點(diǎn)往往為現(xiàn)在，常與完成時(shí)連用。牢牢記住喲。

　　after, in ：這兩個(gè)介詞都可以表示時(shí)間"在以后"的意思。其區(qū)別是：after 以過去為起點(diǎn)，表示過去一段時(shí)間之后，常用于過去時(shí)態(tài)的句子;in 以現(xiàn)在為起點(diǎn)，表示將來一段時(shí)間以后，常用于將來時(shí)態(tài)的句子。

　　by，with，in：by表示"以...的方式，方法，手段" 和 "乘某種交通工具";with指"借助于具體的手段或工具";in 表示"以......方式，用語言，文字等媒介"。

　　for和of：試比較：It's impossible for me to watch TV after eleven o'clock. It's kind of you to help me.

　　兩句中介詞的選擇依據(jù)其前形容詞而定,一般來說,of之前的形容詞往往是用于描寫人的品質(zhì)的好壞，人自身的特點(diǎn)，如聰明與否，細(xì)心與粗心等;for之前的形容詞用于描寫事物的特點(diǎn)，如可能性，必然性，難易程度等。

　　好，又到了趁熱打鐵的時(shí)間了，來檢測一下你的學(xué)習(xí)成效如何?
