1.如何交作业？
本次用直接回复本帖并贴上作业链接的方式来提交第一次作业。也就是：大家的issue和argument都请分别开一个新帖，并用规范的格式。然后将你们帖子的链接贴在这个帖子大家所占的楼里。如我在2搂的示范（请勿占楼不贴作业，给大家完成作业的时间是足够的；也请勿在此主题贴里贴别的东东，以免影响修改！）
2.如何修改？
每人同时修改自己楼上及楼下两位战友的作业。2楼修改3楼和最后一楼（如15楼）的，最后一楼（如15楼）修改2楼及14楼的。其他依次类推……修改的时候请直接在你所要修改的人作文主题贴下方修改。
3.作业期限？
第一次作业在本周四（7月24日）24点前提交，过期不候哦~
4作业题目？
终于到正题了哦！Issue184（最新JJ频率7，排12位，总JJ频率52.）
Argument158（最新JJ排11位）
Issue184 It is a grave mistake to theorize before one has data.
Argument158.
The Trash-Site Safety Council has recently conducted a statewide study of possible harmful effects of garbage sites on the health of people living near the sites. A total of five sites and 300 people were examined. The study revealed, on average, only a small statistical correlation between the proximity of homes to garbage sites and the incidence of unexplained rashes among people living in these homes. Furthermore, although it is true that people living near the largest trash sites had a slightly higher incidence of the rashes, there was otherwise no correlation between the size of the garbage sites and people's health. Therefore, the council is pleased to announce that the current system of garbage sites does not pose a significant health hazard. We see no need to restrict the size of such sites in our state or to place any restrictions on the number of homes built near the sites.
