     On a hot summer day, ice-cold watermelon serves up a delicious treat. Sure, the rosy flesh (果肉) quenches your

thirst (解渴). But now there are more reasons than ever for people to reach for a slice of watermelon.

     Meet Dr. Alison Edwards. She is a scientist at the Agricultural Research Service. Scientists are people who come

up with new ideas called theories (理论). They usually do scientific research to test their new theories. That's how

they find out if a new idea is a good one, or if the new idea will bring an even better idea.

     At her lab, Dr. Edwards recently learned more about the secrets of why watermelon is good for you!

     Dr. Edwards has known for a long time that watermelon has vitamin C. But recently she learned that watermelon

also has lycopene (番茄红素). It is something that gives tomatoes and watermelon their rosy red color.

     What's so special about the lycopene in watermelon?

     Dr. Edwards says that watermelon and tomatoes both have lots of lycopene. It seems that your body can use the

lycopene from   watermelon more easily than the lycopene from raw (生 的) tomatoes.   In fact,    the lycopene from

tomatoes is more easily absorbed (吸收) inside your body once they have been cooked.

近年来，党和政府高度重视社会公平,适时调整最低工资标准。2010年，我国有多个省市调高最低工资标准，部分省市的最低工资标准增幅在20%以上，这牵动了社会敏感的利益链条。面对“涨薪潮”，不同的群体表现出不同的态度。有关网络调查显示：大部分员工认为，工资越高越好，薪水越涨越能提高生活水平；但是，一些经营者却担忧涨工资会加重企业负担，对企业的发展不利。

运用《经济生活》有关知识，对员工和经营的不同态度分别进行评析。（12分）
