The food we ate in the pastis healthier than the food today。(生活類吃飯類)
解析：題目實際上是一種古今對比的題目，即過去和現(xiàn)在食物的健康性對比。這樣的題目我們一般要去寫“總分總”的結構,觀點是同意，過去比現(xiàn)在更健康。
立論文：
過去比現(xiàn)在食物健康：
1. 農藥化肥的使用：(agriculture chemicals/ fertilizer)隨著現(xiàn)代農業(yè)技術(農藥化肥)的使用，現(xiàn)在的食物被污染了,過去的食物是純天然的，(To begin with,the wide use of agriculture chemicals and fertilizers make the food todayunhealthier than the food in the past). This is because the food today arepolluted by these chemical material. For example, in the past, people cleanedthe weeps to safeguard the corn in the field by manual labors. However, farmerswill use herbicide and chemicals to achieve this goal. Therefore, some poisonousmaterial will remain on the crops we eat.
2. 飲食習慣的改變：(changes in the habit of eating are another factorin making the food today much unhealthier) 隨著生活節(jié)奏的加快，人們更多的會選擇吃快餐，(with the life pace accelerating, people today tendto eat the fast food which is nothingbut junk food. By contrast, in the past, people have more spare time, theywould like to cook by themselves) 在過去人們生活更加悠閑，所以會選擇在家里自己做飯。而這些快餐是一些垃圾食品，對我們的身體會有負面影響，比如說造成肥胖，疾病等。
3. (補充：人們道德意識下滑，(the moral standard is degrading),利益熏心 pursue theinterest and profits rather than the quality of food. 三鹿，KFC)
4. 讓步，有的說，我們現(xiàn)在生活水平提高了，人們吃的食物種類更多了，但是我還是認為過去的食物更加健康。
