工作任务一：
目前美国远东贸易有限公司由于金融危机使企业在资金周转上出现了困难。因此Mike打电话给Lily，希望能够采用D/P at 60 days after sight 的付款方式。Lily 在与经理研究后认为，由于这是双方第一次合作，并且货值也比较大。目前外汇市场波动频繁，为了使双方的利益可以得到保障，因此坚持原来的支付方式，但是可以争取交货期提前至6月底。请你以Lily的名义打电话说服Mike接受你们的想法。
L:Hello ,this is Lily speaking ,May I speak to Mike
M:oh ,this is Mike,speaking
L:Mike,i'm Lily,two days ago,you called me,you said:

M: You sure can strive to advance the time of delivery to the end of June L:Yes,sure ,we will
M: That would be fine. I agree with you
