10．A few months ago the potato was considered an enemy in the obesity battle but a new study shows the food isn't that bad after all．In June，researchers from Harvard University found that eating some of the potato[]every day，whether mashed（被磨碎），deep fried or baked，caused more weight gain than an extra can of drink or red or some kind of meat．The conclusion was that it happened because potatoes were always cooked-----making it easier for the body to change the starch（淀粉） which would increase the blood sugar levels．The body then had to work extra hard to get levels down but falling blood sugar made people hungry，which led to eating more food．
But a University of Otago study showed today brought some good news for spud lovers．It found it was hard to tell the glycemic index（GI）（血糖指数） level of mixed meals for persons．"In general，different foods are tested for GI and it is less usual to test the GI for a whole meal，"one of the study's authors，Hayley Dodd，said．"However，in this study，the GIs of three meals were tested．The meals all contained chicken，peas，carrots and mutton together with a lot of food including potato，white rice or spaghetti．"
It found the GI for each meal lower than thought； researchers had expected the potato meal would have a GI of 65，but it came in at 53，which was low．"Although potato is high-GI food into their meals-----our work suggests that having a small amount of potato with a meal isn't going to drive your blood sugar high．
The study involved 30healthy people aged 18-50．The research has been published in the October issue of the American．

分析 几个月前土豆被认为是肥胖的敌人，但一项新的研究显示土豆并没有那么不好．
今年6月，哈佛大学的研究人员发现，每天吃一些土豆，不论是否被磨碎、油炸或烤，都比一罐饮料或者一些肉更容易使体重增加．结论是因为土豆总是被做成食物---更容易改变淀粉导致血糖增加，身体不得不加倍运作但血糖下降让人饥饿，导致吃更多的食物．
但奥塔戈大学的研究今天给土豆的爱好者带来了一些好消息．研究发现血糖生成指数（GI）在混合食物中很难分析．在一般情况下，不同的食品检测到的GI比全餐低．该研究的作者之一，海莉多德说．"但是，在这项研究中，三顿饭的GIs分析食物都含有鸡肉、豌豆、胡萝卜和羊肉一起，很多食物，包括土豆、米饭或面条．"
发现显示每餐的GI指数比想象中的要低．研究人员预期土豆的GI是65，但实际上是53．"虽然马铃薯被认为是高GI食物---但我们的工作表明，饮食中有少量的土豆并不会使你的血糖高．
这项研究涉及到18-50岁的30个健康人，该研究已经在10月份发布在美国的十月期刊上．

Robert Frost was no longer young when he published his first book of poems，A Boy's Will，in 1913．Though born in San Francisco，the USA，he came from a New England family which returned there when he was ten．Like many other writers，he had a brief brush with college and then supported himself by trying different jobs．However，he had been brought up on a farm and he liked farming．Most of all，he liked to write but he could not support himself by writing．In his late 30s he moved to England，where he produced his first book．
At the outbreak of World War I，Frost went back to farming in New Hampshire．From then on，although he made many journeys elsewhere，he considered the farm to be his home and farming activities became the focus of his poetry．
Frost's verses（诗，诗体） are a part of a great tradition，shaped by the Roman poet Vergil，whose poetry was mainly about farming．However，though he used farm situations in much of his poetry，he gave them a wide application．He might write about stepping on a rake（耙子） and describe the feeling when it hit him，but he used the incident to show how life gave us lessons．
Some talents in poetry are used up early，but not Frost's．He continued to publish fine poetry for fifty years．He reached the height of his popularity after World War II．If America had a national poet in the 20th century，it was Frost．He was chosen to read one of his poems at the inauguration（就职典礼）of the late President John F．Kennedy，the first poet ever so honored．
