用所给词的适当形式填空（5分）：
【小题1】I have been in No. 2 Middle School for two years. I don’t worry about not having
(not have) new good friends.
【小题2】The big birthday cake will be divided (divide) into ten parts tomorrow.
【小题3】It is silly of you not to forgive (not forgive) others for their faults.
【小题4】I think he is the most suitable (suitable) person for the job of all.
【小题5】My grandma is in a good mood because tomorrow will be herninetieth birthday. (nine)

解析：【小题1】worry about doing担心做某事, 否定用worry about not doing。句意：我不担心有新的好朋友。【小题2】生日蛋糕将会在明天被分，一般将来时的被动语态，用will be done。句意：这个大蛋糕明天会被分成10块。【小题3】句意：不原谅别人的错误是傻的。It’s +形容词+of sb +to do。【小题4】句意；我认为他是所有人中最适合这份工作的人。形容词最高级+of all。【小题5】句意：我奶奶心情好，因为明天是她九十岁生日。第九十次生日，应用ninety的序数词。
