第7講 介詞
別看介詞是一種虛詞,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系,
不能單獨使用。常考點包括一些固定搭配和一些近義詞。固定搭配如:on one's way home,help...with,send for,be interested in..., be late for, be angry with,be good at等。當然這需要你好好記憶了。
常用介詞解析及用法比較:
at,on和in:這三個介詞在試卷中的出現頻率極高。對于它們的的分辨只要記住一句話就可以了。at表示點,on表示線,in表示面。什么意思呢?也就是說它們表達的范圍逐漸增大。at six o'clock, at noon, at the age of sixteen等用at表示時刻或時間的點以及年齡。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表達的范圍更大一些。與世紀、年代、季節、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表示多長時間。since后接時間起點,其終點往往為現在,常與完成時連用。牢牢記住喲。
after, in :這兩個介詞都可以表示時間"在以后"的意思。其區別是:after 以過去為起點,表示過去一段時間之后,常用于過去時態的句子;in 以現在為起點,表示將來一段時間以后,常用于將來時態的句子。
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的好壞,人自身的特點,如聰明與否,細心與粗心等;for之前的形容詞用于描寫事物的特點,如可能性,必然性,難易程度等。
好,又到了趁熱打鐵的時間了,來檢測一下你的學習成效如何?
