作文：JJ里一道，我努力默写原题了：Jet Software company did not gain an increase of profit in the past three years. Inorder to cut budget costs, the company decide to replace its full-time employeewith temporary workforce. The reason is that auto industry has applied thisstrategy and replace many permanent employees with part-time labor, which greatly increase their profits. Usually, the pay to any temporary employees is onlyhalf or less than that of full-time employees, without any benefits or bonus.Therefore, if our company apply the same strategy and switch 25% of thefull-time workforce to temporary labor, it will lead a great increase in profit and gain a stability in the long term.

阅读：（这个就用中文吧 lol 1. 畜牧业与耕种农作物 herds vs. crop 只有一段，并不长，但是很晕= = 所以我分几点来讲比较清晰： 首先大家公认，用来发展畜牧业和耕种农作物的土地有不同的特点。现在某地发现herds number（畜牧群）减少了，认为是原本发展畜牧业的土地被改成了畜牧业所导致。作者认为不然，然后举了一下三个反例。1）18xx年，woolprice上升，而crop price下降，人们认为是crop的地增多了。作者反驳说其实是因为当时突然流行某种针织物，导致对畜牧产品的需求突然增加（有题）。2）19xx年，农产品产量大幅增加。原因是实施了newarrangement, 对organization re-construction （有题）导致了productivity增加。3）某种程度上，农产品产量的增加对畜牧业也有好处。因为需要很多牲畜去cropthe land。
2. Highland – grassland P1: 某地的highland从前是森林。这个highland发现了28种植物都是只有在forest的条件下才能产生的（有题）。 P2：很多调查人员（高亮考题）认为highland森林的消失与其自然气候有关：在雨季之后会有七个月的旱季。然后作者认为，这种论断忽略了以下两点：一，露珠可以让土壤保持适度；二，fogwill lead water balance P3：既然气候不是forest消失的原因，是什么导致了forest退化成grassland呢？当地有些动物是从其他地方迁徙而来；有些植物是能够同时适应grassland和forest两种条件的。由此说明这些植物是慢慢适应了highland这个地方从forest到grassland的这个变迁过程，而那些没能存活下来的物种很大可能是因为突然的环境变迁，来不及适应而extinction。最后作者猜测，是某年的大火burning导致了highland的forest消失。 3. 女陶瓷工作者那篇，Flairlin的狗写的非常清晰，不重复了~在此感谢！ 4. Solar energy那篇，基金很详细了，不重复了。。
