One reason is that eating these types of food reduces the risk of acid accumulation(积累) in your body.Raw and whole foods are usually digested more efficiently than cooked and refined foods.When we cook foods,we destroy the natural enzymes (酶) that are part of the food in its raw form.These enzymes were intended by nature to help us digest the food.When we consume food without these natural enzymes,our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream.In both instances,the result is obesity(肥胖).When too many nutrients are absorbed at once,the body grows fat.Improperly digested food moves slowly through the digestive tract(消化道),where it becomes increasingly acidic.To protect its vital organs from this acidic waste,the body changes the acid into fat and stores it safely away from the organs.Processed foods contain chemical elements,which might confuse the appetite mechanism that tells us when weve had enough to eat; as a result,people often overeat.Processed foods also upset the digestive cycle.The body will either identify these foods as allergens(过敏原) and then store them safely away from the organs as fat,or the remains of undigested food will become acidic and enter the bloodstream as acid waste,which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the bodys cells.The bodys metabolism (新陈代谢) becomes inactive,and the result is weight gain and obesity.The accumulation of acid in the digestive tract makes digestion increasingly inefficient.When that happens,even healthy foods can become acidic and the food allergies will become more common.To stop this vicious circle in its tracks,people need to consume food and supplements that will neutralize(中和) the acid already accumulated in body.Eating the right types of raw and whole foods can help.Its also important to restore your enzyme balance.You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production.If you truly want to change and help your body heal itself,you need to take an active approach.11.It can be inferred from Para.2 that .A.wed better be cautious about raw and whole foodsB.foods with natural enzymes help people keep fitC.it is essential for people to protect their vital organsD.giving up cooked and refined foods is a new lifestyle答案B解析推理判断题。根据第二段的句子“When we cook foods,we destroy the natural enzymes (酶) that are part of the food in its raw form.These enzymes were intended by nature to help us digest the food.” 可知,有天然酶的食物可以有助于消化,从而让人们保持健康。故选B。12.Processed foods are unhealthy because they .A.destroy bodys cellsB.are difficult to digestC.may lead to obesityD.stop bodys metabolism答案C解析细节理解题。根据第三段的内容可知,加工过的食物会使人经常吃得过多并且会扰乱消化循环,从而导致肥胖。故选C。13.What is the main purpose of this passage?A.To warn people of the problem of obesity.B.To inform people of the harm of processed foods.C.To advocate eating more raw and whole foods.D.To tell the differences between raw and processed foods.答案C解析主旨大意题。文章主要介绍未加工的整的食品的好处和加工过的食品对我们健康的害处,也就是提倡吃更多的未加工的整的食物。故选C。14.What is likely to be talked about following the last paragraph?A.Different causes of acid accumulation.B.Correct ways to cook raw foods.C.Active approaches to avoid acid.D.Suitable types of raw and whole foods.答案D解析推理判断题。根据最后一段的句子“Eating the right types of raw and whole foods can help.”可知,接下来作者会介绍适当的未加工食品的种类。故选D。BAlmost every machine with moving parts has wheels,yet no one knows exactly when the first wheel was invented or what it was used for.We do know,however,that they existed over 5,500 years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didnt become popular for a while,though.This could be because animals did a perfectly good job of carrying farming tools and humans around.But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces(光滑表面),roads with smooth surfaces werent going to be built until there was plenty of demand for them.Finally,road surfaces did become smoother,but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid1700s,a Frenchman came up with a new design of roada base layer (层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong,lasting road surface became a reality.At around the same lime,metal hubs (the central part of a wheel) came into being,followed by the pneumatic tyre(充气轮胎) in 1846.Alloy(合金) wheels were invented in 1967,sixty years after the appearance of tarmacked roads (柏油路).As wheel design took off,vehicles got faster and faster.15.What might explain why transport wheels didnt become popular for some time?A.Few knew how to use transport wheels.B.Humans carried farming tools just as well.C.Animals were a good means of transport.D.The existence(存在)of transport wheels was not known.答案C解析细节理解题。根据文章第二段最后一句“This could be because animals did a perfectly good job of carrying farming tools and humans around.”可知,动物们能够很好地运送农耕工具,充当人们的出行工具,因此很长一段时间内交通工具的轮胎不受欢迎。故选C。16.How is the last paragraph mainly developed?A.By giving examples.B.By making comparisons.C.By giving discussion.D.By making classifications(分类).答案A解析推理判断题。根据文章最后一段可知,作者通过一个法国人和一个苏格兰人的发明为例讲述了轮胎改进的历史。故选A。17.What is the passage mainly about?A.The beginning of road design.B.The development of transport wheels.C.The history of public transport.D.The invention of fastmoving vehicles.答案B解析主旨大意题。通读全文可知,第一段和第二段讲述了轮胎的起源,第三段和第四段讲述了轮胎的发展和改进的历史,由此可知这篇文章主要讲述交通工具的轮胎的发展史。故选B。.语法填空Interviewer:May I ask you a few questions,sir?Jack:Of course you can.Interviewer:Thank you,sir.First
