阅读jj就碰上一个feminism+women's rights.
有个是 cargo ship produce Sulfur dioxide 结合了云上的啥东西让incoming solar radiation reflected back into space. the effect is cooling of the atmosphere. 但这不能长远的帮助保护地球因为船释放的CO2 超过它释放的SO2 所以并没啥用。文章不长,比较好理解
还有个是说venus 上的canali,细节不记得了看看有没有考古吧
数学jj没碰上几个,有个jj里的64题。一个半圆,下面一个长方形。答案选项里好像有1/3pi,2/3pi, 4/3
PS.记得第一题是卖票的。成人买了60%的票剩下的是小孩儿买的。X代表adult买的数量,Y代表children买的数量。adult 买的金额占总金额的百分之75%。问小孩大人各买的多少张票。
PS. ax+by=cz 问how to represent z
选项有|ax|+|by|/|c| |ax+by|/|c|
作文:Neoelectric 's ceo says eight years ago the revenue employees made was higher than their salary but recently the company's profit is declining. even though they are hiring more people but their ability doesnt justify their salary. 能力没有以前员工的好了。怪human resource department 没有做好他们的工作。
