語(yǔ)法復(fù)習(xí)二十：介 詞
介詞又叫前置詞，是一種虛詞。介詞分為三種，一種是簡(jiǎn)單介詞，如at, in, on, beside, to , for等；另一種是短語(yǔ)介詞，即由兩個(gè)以上的詞組組成的短語(yǔ)，如in front of, because of, out of, instead of等；還有一種叫二重介詞，如until after, from behind等。�。ㄒ唬┙樵~的句法功能
介詞不能獨(dú)立在句中做成份，介詞后必須與名詞、代詞、或動(dòng)名詞構(gòu)成介詞短語(yǔ)在句中充當(dāng)一個(gè)成份，表示人、物、事件等與其它人、物、事件等之間的關(guān)系。

2、作狀語(yǔ)：We have breakfast at seven.（表時(shí)間）；They were late for meeting because of the heavy rain.（表原因）；They started the machine by pressing the button.（表方法）
3、作表語(yǔ)：My dictionary is in the bag.
