arrange
1.We have arranged (for) the concert, They are arranging (for) a picnic等句子里的for不用的多，用的少。注意concert和picnic都是事，不指东西或人。We have arranged for a new classroom和They are arranging for a guide等句子里的for不可省去。
2.I have arranged for him to go是“他去”，不是“我去”。I have arranged with him to go也许“我去”，也许“他去”，也许“我和他一同去”。I have arranged with him to let me go当然是“他让我去”。在容易被人误解的场合，该避免I have arranged with him to go一类的句子。
3.arrange（安排、预定）后面可以接以that引导的从句，那从句里用shall或should，如We have arranged that he shall（或should）start work next Monday和We arranged that he should start work next Monday。也可以用虚拟现在式。例如：We (have) arranged that he start work next Monday.
