declare可用作及物动词与不及物动词、可用于被动语态等。具体如下：
1、declare既可用作及物动词,又可用作不及物动词。用作及物动词时,其后接名词、代词或that从句作宾语。不接动名词,也不接动词不定式。可用于被动语态。
2、declare后可接由to be/as加名词、形容词、副词或介词短语充当补足语的复合宾语。to be/as有时可以省略。
3、declare接复合结构时可以用动词不定式或由wh-引起的疑问词从句作宾语,但它们都由it代替,而它们本身则移到补语后面,此时它的补语多为形容词。
4、declare作不及物动词时常跟介词against表示“声明反对”,接for表示“宣布支持”。

近义词区分
declare, announce, proclaim, publish
这四个词都有“宣布”的意思。其区别是：
1、从主语上说, proclaim的主语只能是权力机关或政府首脑; announce, declare和publish则既可以是权力机关或政府首脑,也可以是普通个人。
2、从宾语上说,即宣布的内容上说, announce指公众关心的,特别是具有新闻性的事件。例如:
The rise of prices of grain was announced in the papers.粮价上涨已在报上公布。
3、declare指重要的决策、举措或意见。例如:
The government declared rubber a strategic and critical material.政府宣布橡胶为重要战略物资。
4、proclaim指意义重大的事情。例如:
The founding of the United Nations was proclaimed in 1945.1945年联合国宣告成立。
5、从宣布的方法上说, announce, declare, proclaim既可指口头地,也可指书面地; 而publish则主要指印成文字地。
6、从宣布的目的上说, announce, proclaim, publish在于使众所周知; 而declare则在于使人明白。例如:
The arrested man declared himself innocent.被捕的人声称自己是无罪的。
7、从使用场合上说, proclaim用在正式场合; declare主要用于正式场合,也可用于非正式场合; announce则不如proclaim和declare正式庄重,可以用于一般场合,也可用于官方正式公告。
