（二） 　　朱某原是大鹏公司的采购员，已辞职。某日，朱某接到大鹏公司的进出口业务代理商某粮油进出口公司业务员的电话，称该公司代理进口的3000吨特级糖蜜因买主某食品厂急需资金欲低价转卖，大鹏公司如有意购买，务于晚饭前回复。朱某紧接着就打电话找大鹏公司经理，经理正出差，要晚上才回来。朱某赶到粮油公司，说货物大鹏公司要了。粮油公司不知朱某已辞职，就与其签了合同，并说糖蜜存放在仓库，你们把货款和仓储费付清，我们把仓单背书给你。朱某当晚带着已签好的一式两份合同和糖蜜的样品，找到大鹏公司的经理，经理看了合同和样品后，在合同上签了字，并要朱某第二天到公司去盖章。大鹏公司将钱款付清后，拿着仓单到仓库提货，在验货时发现是一级糖蜜，就未取货。原来粮油公司怕大鹏公司不能及时付款，把那批特级糖蜜给了别人。这批一级糖蜜合同上订的也是特级，口岸验收时商检局发现货轮有轻度污染，就给降了一级，由特级改为一级。请回答以下85－88题。

In the world of entertainment, TV talk shows have undoubtedly flooded every inch of space on daytime television. (1) But no two shows are more profoundly opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey show.
Jerry Springer could easily be considered the king of"trash talk". (2) For example, the show takes the ever-common talk show themes of love, sex, cheating, guilt, hate, conflict and morality to a different level. (3)
Like Jerry Springer, Oprah Winfrey takes TV talk show to its extreme, but Oprah goes in the opposite direction. (4) Topics range from teaching your children responsibility, managing your workweek, to getting to know your neighbors.
Compared with Oprah, the Jerry Springer show looks like poisonous waste being dumped on society. Jerry ends ever with a "final word". (5) Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. (6) Most of these people have the time, money, and stability to deal with life’s tougher problems. Jerry Springer, on the other hand, has more of an association with the young adults of society. (7) They are the ones who see some value and lessons to be learned underneath the show’s exploitation.
While the two shows are as different as night and day, both have ruled the talk show circuit for many years now. (8) Ironically, both could also be considered pioneers in the talk show world.

• F. These are 18-to 20-year-olds whose main troubles in life involve love relationship, sex, money and peers.
• G. And anyone who watches them regularly knows that each one varies in style and format.
• H. Clearly, the Jerry Springer show is a display and exploitation of society’s moral catastrophe, yet people are willing to eat up the intriguing predicaments of other people’s lives.
