Eat fewer calories,but more food
Slimming down can help prevent disease,and cutting way back on the amount you eat may even slow the aging process.When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health:Pile your plate high with vegetables and fruits,add respectable parts of beans and whole grains,and ignore high-calorie food like cheeseburgers,cream sauces,and fatty meats.
Use exercise as an anti-aging vaccine
Exercise can help you gain a better quality of life as you age.It's no secret that physical activity strengthens muscles,burn calories,and puts a happy bounce in your step.But recently,researchers discovered a new,extra benefit:Exercise acts as a powerful way against the aging process itself.When exercise physiologists put healthy people aged 60to 85on Weight-training programs for six months then tested them for signs of free-radical(自由基) damage,they were surprised by the results.By the end of the study,low-intensity exercisers had a drop in free-radical damage,while high-intensity exercisers had a slight increase.

點評 1、要想做好科普英語閱讀理解題,同學們就要注意平時多讀科普知識類文章,學習科普知識,積累常見的科普詞匯,從根本上提高科普英語的閱讀能力.
2、要熟悉科普類文章的結(jié)構特點.科普類文章一般由標題(Head line),導語(Introduction),背景(Back ground),主體(Main body)和結(jié)尾(End)五部分構成.標題是文章中心思想高度而又精辟的概括,但根據(jù)歷年的高考情況來看,這類閱讀理解材料一般不給標題,而要同學們選擇標題.導語一般位于整篇文章的首段.背景交待一個事實的起因.主體則對導語概括的事實進行詳細敘述,這一部分命題往往最多,因此,閱讀時,同學們要把這部分作為重點.結(jié)尾往往也是中心思想的概括,并與導語相呼應,命題者常在此要設計一道推理判斷題.
3、在進行推理判斷時,同學們一定要以閱讀材料所提供的科學事實為依據(jù),同時所得出的結(jié)論還應符合基本的科普常識.
