declare open the 2010 Asian Games是一种宾语补足语提前到宾语前的常见结构,正常语序应该是declare the 2010 Asian Games open,其中the 2010 Asian Games 是declare的宾语,open 是作宾补的形容词.这种情况常发生在宾语较长的时候.如：
We shall lay open all their secret plans. (=lay all their secret plans open) 我们将揭露他们所有的秘密计划.
You needn’t let open your journey on business. (let your journey on business open) 你不必公开你出差的行程.
同样的用法还有由和介词同形的小品副词构成的短语动词,如：
give sth. up / give up sth. 放弃某事
put sth. off / put off sth. 推迟某事
如果这类短语动词的宾语是人称代词 it,him,me,you 等或者宾语较长时,都要求把小品副词提前到宾语前.
