高二英語選修七單元知識點總結1

介詞又叫前置詞，是一種虛詞。

介詞分爲三種，一種是簡單介詞，如 at, in, on, beside, to , for 等;另一種是短語介詞，即由兩個以上的詞組組成的短語，infront of, because of, out of, instead 如 of 等;還有一種二重介詞，如 until after, from behind等。

(一) 介詞的句法功能：介詞不能獨立在句中做成份，介詞後必須與名詞、代詞、或動名詞構成介詞短語在句中充當一個成份，表示人、物、事件等與其它人、物、事件等之間的關係。

1、 作定語： The book on the table is mine.

2、 作狀語： have breakfast at seven. We (表時間)They were late for meeting becauseof the heavy ; rain.(表原因) ;They started the machine by pressing thebutton.(表方法)

3、 作表語： My dictionary is in the bag.

4、 作賓語補足語： I found him in the office.

(二) 1.表示時間的介詞

(1)in表示“在某一時間段”或“在某一時候”，如用在月、季、年份、時代、世紀等時間名詞的前面，或用來泛指一天的某一段時間。in也可以指“在……之後”，表示從說話起的若干時間內。

如： in July/summer/2000/ancient times

The bus will be here in ten minutes.

(2) on表示“在特定的某一天”，也可用於帶有修飾語的一天的某個時間段之前。如：on Saturday, on Saturday morning,on the morning of August 1st

(3) at表示“在某一時間點”，或用來表示不確定的時間和短期的假日、時節等。

如：at six o'clock, at Easter

(4) over, through (out)兩者均指“經過的全部時間”。

如：Stay over the Christmas.

(5)for與since：for表示動作或狀態延續的全部時間長度，爲“長達……”之意;since用於指從過去特定的某個時刻到說話時爲止的一段時間;含有since時間短語的句子要用完成時，但含有for時間短語的句子不一定要用完成時。
