    （1）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，在句中充当一个成分。介词分为：简单介词，如at、in、for等；合成介词，如within、inside、onto、througout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。

常见的介词宾语：名词、代词、动名词、从句、不定式等。如：
