And her parents are ud of their daughter very much, because she is always(careful)to do angthing.此题括号中为什么不能用carefully.请详细说明！谢谢！！-Would you please keep the door(closed)?It's so cold today.-Sure,I'll do it at once.此题括号中为什么不能用close? 
回答：1.这是be  careful to do sth  而不是修饰某动词
 ep sth ...自然后面应是形容词而close 是不能表示“关着的”这一意思的
倒是有be close to sth /sb
