I found this computer game_______ to play

I found this computer game_______ to play
I found this computer game_easy_ to play
为什么不用easily
不是修饰 found

1.有句型：I found sth. adj.
比如,I found the man very foolish.
而此句中多了个“to play”,你可以把“to play”看作是“the computer game is easy”的一种修饰,也就是用“to play”说明,这个电脑游戏在什么方面容易-----这个电脑游戏玩起来很容易.
2.看到这个题,你应该很快想到这个句子：It’s easy to play the computer game.这时,你也就应该知道是选easy而不是easily了. 好好领悟吧
