Eating Spinach Makes You Mentally SharpWhile Popeye ate spinach1 every day to maintain strong muscles，he was also bettering his memory，maybe without even knowing it.Consuming just a daily serving of spinach—or any type of leafy green，for that matter—may help slow the process of age－associated cognitive decline2，according to a new study.The reason？Vitamin K.A group of researchers at Rush University in Chicago who analyzed the diets and mental functions of 954 elderly people over a five－year period found that those who ate more greens in their diets were more likely to be mentally sharp.The researchers tracked the diets of participants，whose age averaged 81，for an average of five years.They found that people who ate one or two daily portions of green leafy vegetables had the same cognitive abilities as someone 11 years younger who never consumed leafy greens.“No other studies have looked at vitamin K in relation to change in cognitive abilities over time，and only a limited number of studies have found some association with lutein3，” said Martha Clare Morris，Sc.D.，assistant provost for community research at Rush University Medical Center and the leader of the study's research team.The team believes that other foods high in these nutrients，like asparagus4 andcarrots could provide the same benefits as the darker greens，and they intend to expand their research to explore this possibility.The research holds promise of a brain booster5that is accessible and affordable.“Since declining cognitive ability is central to Alzheimer's disease and dementia，increasing consumption of green leafy vegetables could offer a very simple，affordable and non－invasive6 way of potentially protecting your brain from Alzheimer's disease and dementia，” Morris said.Notes1．spinach n．菠菜2．cognitive decline 认知衰退3．lutein n．叶黄素4．asparagus n．芦笋5．booster n．助推器，辅助药剂6．non－invasive adj.非侵入的TaskWhich of the following is FALSE according to the passage?A．Vitamin K may help slow the process of age－associated cognitive decline.B．The researchers tracked the diets of participants for an average of five years.C．Only a limited number of studies have found lutein has the same function as vitamin K.D．The team believes carrots could provide the same benefits as the darker greens.答案 C。

Opinions are divided.Some believe that human cloning is a good thing. Firstly, They think if people had too much work to do , they could get their own clone to help them. That wouldn’t be cheating because it would still be themselves doing the work. As a result, they would have so much time to rest and have fun. What’s more, human cloning could alsosolve the problem of finding the organs for organ transplants. Sothat it could help people lead longer and healthier lives.However, others are against it .They think human cloning is a terrible idea, which could cause a lot of problems. First of all, it could cause family confusion. If people were cloned , how could their clone fit into their family? Remember, their clone would be exactly like them. In addition, clone could cause problem for society. If everyone decided to be cloned there would be a population of explosion.In my opinion, I ’d prefer to have human cloning .

Unit 21 Human Biology【美文阅读】Nearly third of children globally are couch potatoesAmerican children aren't the only couch potatoes with nearly one third of children globally spending three hoursa day or more watching TV or on computers，according to a study of over 70,000teens in 34 nations.From Argentina to Zambia，Regina Guthold of the World Health Organization inGeneva and her colleagues found most children aren't getting enough exercise andit made no difference if they lived in a rich or a poor country.“With regards to physical activity levels，we did not find much of a differencebetween poor and rich countries，”Guthold said.“Growing up in a poor country does not necessarily mean that kids get morephysical activity.”They study looked at 72,845 schoolchildren aged 13 to 15 from North and South America，Asia，Europe，and the Middle East.The children were surveyed between 2003 and 2007.The researchers defined adequate physical activity as at least an hour of exercise outside of gym class at least five days a week.Children who spent three or more hours a day watching TV，playing computer games，or chatting with friends－aside from time in school or time spent doing homework－were classified as sedentary(惯于久坐)．The researchers found only one quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions.A quarter of boys and nearly 30 percent of girls were sedentary and didn't get enough exercise with girls less active than boys in every country aside from Zambia.Uruguay had the highest percentage of active boys，at 42 percent，while Zambia had the lowest，at 8 percent.Girls from India were the most active，with 37 percent meeting exercise recommendations，while girls from Egypt were the least active，with just 4 percent getting adequate exercise.Children in Myanmar(缅甸)were the least sedentary，with 13 percent of boys and 8 percent of girls classified as sedentary.The most sedentary nations were the Cayman Islands(开曼群岛)，with 58 percent of boys and 64 percent of girls spending at least three hours a day in sedentary activities.While the study didn't look at the reasons behind the lack of physical activity in various nations，Guthold speculated(推测)that urbanization could be a factor as well as access to cars and TVs.【诱思导学】1．What is the meaning of couch potatoes?2．What leads to the children's lack of physical activity?【答案】 1.Couch potatoes mean some people who spend most of his or her free time sitting or lying on a couch，watching TV，and it means that they are lazy.2．Urbanization could be a factor as well as access to cars and TVs.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课就课文的全面理解起到一个铺垫作用。
