掌握好英语.

我大致翻译了一下——
牛奶+橙子?
如果是常识,即橙子不能和牛奶一起吃,那是非常糟糕的.（那么）当我们把橙汁和冰淇凌一起购买时,为什么诸如肯德基、麦当劳这些洋快餐没有告诉我们?
问题回答：
现代营养学把食物分酸碱两性.酸碱之性并非指其入口之味,而是指食物在人体代谢之后的最终产物是呈酸性还是呈碱性.营养学总体要求人体酸碱平衡.掌握食物的酸碱性把握膳食的营养平衡是营养科学身体健康的重要标志.
酸性食物：有肉鱼蛋禽,谷类,硬果（如：榛子、花生、核桃）,水果（如：李子、梅子、橙子、葡萄干、杏、山渣等）.酸性食物含氯、硫、磷元素高,使人体血液呈酸性,易疲劳,但溃疡、胃酸过高者不宜食.
碱性食物：有水果蔬菜,牛奶,豆类,茶水,硬果（如：杏仁、栗子、椰子等）.碱性食物含钙、钠、镁、钾较高,可使人精力充沛.但消化不良,胃酸偏低者忌食.
中性食物：有黄油、奶油、植物油、淀粉、糖等,中性食物含碳氢氧元素高.但动脉硬化患者忌食.
酸性的橙子与碱性的牛奶一起食用,容易中和产生不易消化的结石,长期食用,便会使这些结石在肾脏累积,形成肾结石,严重影响身体健康.
因此,牛奶浴橙子不宜同食.
至于K和M为什么不进行及时提醒,我认为,一是经济利益,二是他们无知或不重视.这就难怪营养学家把K和M定为垃圾食品了.
友情提示：
为了你的身体健康,建议你还是少光顾这些洋快餐.

嗯嗯,同意一楼的,在形容词前加the,意指一个人群,像：
the poor 穷人
the rich 富人
还有你说的 the old/ aged 老人

most 在这是副词,本来就是来修饰 common 的,一般不用词来修饰,就像楼上所说的,可以用一些序数词来修饰.

a：the 第一个空填a 是因为problem是非特指的,后面的of the aged不是限定,只是一个指向,对老年人来说的一个问题.第二个空填the是因为在形容词前加the,意指一个人群,像：the poor 穷人the rich 富人 the old/ aged 老人

What I do is about Sony notebook’s questionnaire. At Present notebook is very popular, nearly all participants have expressed that they are using a notebooks. The import brand seems more popular than domestically produced brand. Most respondents have said they pay more attention to import brand's high quality and durability when buying notebooks. Of course, most of the import notebooks are big brand is part of the reason.
I investigate users of a series of questions about Sony notebook such as the price, its market development prospect, the post-sale service, the brand effect, the battery endurance, the design style; the staff sells ability, the quality and the disposition.
According to the investigation, almost 80% students are satisfied with the Sony notebook in the world's prospects for development, and the notebook performance, the grade of service, but 90% of the students can't accept the price. In my opinion, although its factory is taken to China, there have been little manifestations in the price; the price is still very expensive. Especially since 2004, Sony personal computer in Japan experienced large scale loss. Therefore the price adjustment and indepth knowledge of Chinese market's still require improvement. 90% people agree the Sony brand has brilliant influence all over the world. But 70% people think the battery doesn’t last long enough. 50% people are attracted by the changeable style. Almost all the people take fancy to the reliable quality. 80% of the staff sales personnel’ vocational level should be improved .30% students are not know much about the sharpcloud and not pay much attention to it. In total, I think it’s a reliable brand.
