consist compose comprise constitute的区别

这四个词都有组成构成的意思.
consist是不及物动词,得加介词用 consist of,例如The United Kingdom consists of Great Britain and Northern Ireland.
compose既是及物动词也是不及物动词,作为构成的意思的时候是及物动词,而且要用被动语态be composed of,例如Water is composed of hydrogen and oxygen.另外compose还有创作的意思,是作为不及物动词使用的,例如He was composing at the piano at the age of seven.
comprise是及物动词,当作组成构成的意思时候,可以用be comprised of,等同于be composed of,例如A football team is comprised of eleven players. 也可以直接coomprise加名词或代词,不需要加介词,等同于constitute,例如Fifteen separate republics comprised the Soviet Union. 另外它还有包括包含的意思,等同于include,contain,incorporate,例如This month's figures are comprised in the total.
constitute 是及物动词,不需要加介词of,例如 Twelve months constitute one year.而且constitute一般多用于机构 ,组织的构成
