* 介 词 介词的分类 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，在句中充当一定成分。　　 介词分为：简单介词，如at, in, for等；合成介词，如within, inside, onto, throughout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。 介 词 一、方位介词 1．above，over，on；below，under，beneath (1)above侧重于相对水平高度，不一定在正上方，其反义词是below。 (2)over侧重于垂直高度，即位于正上方，其反义词是under。 (3)on侧重于与物体表面接触，其反义词是beneath。 Be careful; there is a heavy box over your head. The position he pointed to was below the sea level. 2．across，over，through，past across意为“横穿, 穿越”，表示运动发生在物体的表面。over意为“跨过，越过”，表示运动发生在物体的上方。through意为“穿过，通过”，表示运动发生在某物的空间内。past意为“从……旁经过”，表示运动发生在某物的旁边。 The Great Wall winds its way from west to east，across desert，over mountains，through valleys till at last it reaches the sea. 3．in，on，to在方位名词前的区别 in表示在范围之内；to表示在某范围之外的地方；on表示“毗邻”“接壤”。 Shandong Province is/lies in the east of China. Japan is/lies to the east of China. 二、时间介词 1.at，in，on，by，after 2.for，from，since for后接时段的名词词组，表示行为状态持续了多久。from接时间点的名词词组，表示行为或状态的起始点，而不涉及其持续时间的长短。since接时间点的名词词组，不仅表示行为或状态的起始点，而且还强调该行为或状态从起始点一直持续到此时此刻，因而与延续性动词的现在完成时连用。 Mr. Brown enjoyed the country life and lived there for almost fifteen years after his retirement.
