“An_apple_a_day_keeps_the_doctor_away.” is not as silly as some people think.The body needs fruit and vegetables because they contain vitamin CMany people take extra vitamins in pill form(丸剂)，believing that these will make them healthy.But a good diet is made up of nourishing food and this gives all the vitamins you need.The body doesnt need or use extra vitamins，so why waste money on them?In the modern western world，many people are too busy to bother about eating properly.They throw away the good habits and throw anything into their stomachs，eating hurriedly and carelessly.The illnesses caused or made worse by bad eating habits is frightening.1From the first sentence we know that_.Athe more you eat，the better you will feelByour body is made up of the food you

years可判断出一定遇到了许多困难。4Ccant表示否定的推测，意为“不可能”，合乎题意。5Ashall用于第二人称，表示警告。6Ashall与第二、三人称连用表示命令、规定和要求，译为“应该，必须”。7Cso that引导的目的状语从句中通常要使用can/could，will/would，may/might等情态动词。前半句是过去时，所以要选C项。8B表示对过去发生情况的推测用“情态动词完成式”，而根据语境应表示“某事那时不可能”，因此B项符合语境。9B语境表示过去发生的情况。因此答案为B。could have done sth.意为“本可以做”。10Bcant have done意为“不可能做过某事”。11Doughtnt to have done表示“本不应该”。12Cmust be doing是对目前正在发生的事进行推测，意为“他此时一定在楼上做作业”。13D句意为：我不介意把我所知道的告诉你。你不必告诉我，我没有要你告诉我啊。此处need表示“必要”。14B句意为：我们可能没能证明这是个伟大的探险，但我们已经取得了过去10年中最大的进展。15B.1.C推理判断题。文章的第一句告诉我们，我们的身体与我们所吃的食物密切相关，因此需要妥善对待身体和合理摄取营养。2B细节理解题。从上下文可知，按规律进食苹果对我们的身体大有好处。其他选项均太片面。3D细节理解题。纵观第二段，通过讲述西方人的不良饮食习惯，强调好的饮食习惯对保持身体健康十分重要，即D项表述正确。A、C两项是从第一段内容得出来的；B项不是文章讲述的，故排除。4A推理判断题。全文讲述了合理饮食对保持健康的重要作用，故选A项。.参考范文Dear Kate，Im writing to tell you about the importance of healthy eating.I heard that you dont like to have your meals on time and that junk food is your favourite.Id like to give you some advice on this.As we all know，junk food，such as hotdogs，hamburgers，soft drinks，chocolate and candy，contains a lot of fat and is high in calorie.Therefore，eating too much junk food will be bad for you.It may satisfy your appetite，but it can also affect the function of the stomach，and this can lead to obesity.In particular，it can lead to heart disease and cancer.So I strongly suggest that you shouldnt eat junk food any more.In my view，you should develop a good eating habit to ensure you have a balanced diet that is good in nutrition.First of all，you should eat three meals every day，and should also eat more fruit and vegetables.I hope you will find these suggestions useful.Yours，Li Hua
