However, while enjoying their free college life, they often end up suffering from poor eating habits that lead them to put on weight and even damage their health.,Part A Text,A common error is underestimating serving sizes, meaning they often eat more than they think they are eating. They eat too much junk food and they have too many alcoholic drinks which are filled with empty calories and help contribute to a worsening diet. They also eat sporadically, eating a huge breakfast (or no breakfast at all) before classes, and then cramming in as much food as they can during their lunch break. As a result, some students will put on 15 or more pounds during their first year of college, which is called the Freshman 15.,Part A Text,Many of these students will then go on a diet to lose weight. But the problem is, usually we cant maintain that low level of calorie intake, and as soon as we stop eating at that low level, it comes right back. Thus they fall into a cycle of losing weight, going back to their original diet, and quickly putting back on all the weight. This up-and-down weight loss is unhealthy for the body and the heart.,Part A Text,There are many reasons that college students have these eating habits. One of them is a lack of money. College is expensive, and even though financial aid can help cover these expenses, students often dont have a lot of money left to live. Healthy eating can be expensive. Many energy-dense foods are not only the least expensive, but also the last to rise in price. A lack of time also makes it difficult for college students to eat healthy food. ,Part A Text, Full-time students usually have 12 to 16 hours of class per week. These classes are often spread throughout the day sporadically, leaving little time for them to cook. Then there are the college cafeterias. Many of these are of the “buffet” variety, where students can pick whatever they like and eat as much as they want, leading to overeating.,Part A Text,It can be really hard for college students to avoid these habits. They are simply the easiest ways for them to eat, and breaking the cycle of poor diet can be expensive and time-consuming. However, its important to have a balanced diet. Instead of grabbing that extra slice of pizza at the cafeteria, grab an apple and an orange with fewer calories, but more nutrition and energy. Instead of drinking soda, drink water which is free. Dont buy high-calorie ramen noodles, buy whole-wheat spaghetti and low-fat sauce. Try to cut back on drinking as well. (453 words),大学生与饮食 上大学，对多数大学生来说，是第一次离家独立生活。他们享受着自由的大学生活，但最后往往会养成不良的饮食习惯，导致体重增加，甚至营养不良。,Part A Text Translation,常见的错误就是低估食物的份量，也就是说他们吃进去的比自己认为的要多。他们吃太多垃圾食品，喝太多含酒精饮料而摄入无营养价值的热量，从而导致饮食恶化。他们饮食很不规律，上课前吃超大一份早餐（或者什么都不吃），午餐又放开胃口大吃特吃。结果，有些学生在第一年体重会增加15磅甚至更多，这被称为“新生15磅”。,Part A Text Translation,接着，这些学生多会通过节食来减肥。但问题是，通常我们不可能长期维持低热量的摄取，所以一旦停止节食，体重马上反弹回来。于是他们陷入了一个节食减肥、正常饮食、迅速反弹这样一个循环。体重如此反复增减，对身心都不健康。,Part A Text Translation,大学生养成这样的饮食习惯是有很多原因的。其中之一就是他们缺钱。上大学的费用很高，即使助学金能解决这部分开销，但留给学生的生活费就不多了。健康饮食往往花费很多。许多热量高的食物不仅价格最便宜，而且是最不容易涨价的。时间紧张也是大学生很难健康饮食的原因。 ,Part A Text Translation, 全日制学生每周基本有12到16小时的课程。一天的课往往安排得很不集中，这样学生就没时间自己做饭了，所以他们就去学校食堂吃。这些食堂大部分是自助式的，学生可以尽情地挑自己喜欢的东西吃，结果导致饮食过量。,Part A Text Translation,对大学生来说，要避免这些坏习惯很难。这样吃其实是最简单省事的，要改掉这种不良饮食习惯既耗财又耗时。但合理饮食很重要。在自助食堂就餐后不要再抓一块比萨塞到嘴里，而应拿个热量低点、营养和能量高点的苹果和桔子吃。不要喝汽水，而应喝直饮水。不要买高热量的拉面，而应买全麦意大利面条和低脂调味酱。另外，尽量少喝酒。,Part A Text Translation,without anyones help; alone, without anyone else e.g. We cannot solve this problem on our own. 我们无法解决这一问题。 I may get lost on my own. 我单独一个人可能会迷路。,Part A Text Language Points,to come to be in a particular situation or state, especially when you didnt plan it e.g. At first they hated each other, but they ended up getting married. 他们起初相互仇恨，到后来却成了夫妻。 Wasteful people usually end up in debt. 挥霍浪费者最后往往负债。,Part A Text Language Points,v. to think or guess that the amount, cost or size of something is smaller than it really is e.g. We underestimated the time it would take to get there. 我们低估了抵达那里所需的时间。 People often underestimate the importance of training. 人们常常低估培训的重要性。,Part A Text Language Points,n. an amount of food for one person e.g. This recipe will be enough for four servings. 本食谱为四人量。 Serving size As determined by the Food and Drug Administration (FDA) in USA, serving size is the portion of food used as a reference on the Nutrition Facts on food package labels to indicate the amount customarily consumed or the recommended amount to be eaten, e.g. serving size 1 cup (228g).,Part A Text Language Points,Note: It is possible for young people to underestimate the serving sizes because of their good appetite. But according to a New York Times article, “One Bowl=2 Servings. F.D.A. May Fix That.” by William Neuman ( =1), food producers would never like to scare off their consumers with the real calorie counts, so they often put smaller serving sizes on the food packages, which may contribute to the underestimating.,Part A Text Language Points,food that is quick and easy to prepare and eat, but that is thought to be bad for your health when regularly eaten Note: This is an informal term coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972. Junk food includes foods such as soft drinks, hamburgers, hot dogs, ice cream, cake, French fries, chocolate and other confectionery, pizza, cookies, fried chicken, onion rings and donuts.,Part A Text Language Points,drinks such as beer or wine that contain a substance that can make you drunk e.g. The airlines have turned to alcoholic drinks to keep its planes full of passengers. 航空公司向乘客提供含酒精的饮料以使航班满座。 Alcoholic drinks is not allowed into certain countries. 有些国家禁止带入含酒精的饮料,Part A Text Language Points,foods that are very high in energy but low in nutrients such as vitamins, minerals, fiber and essential fatty acids,Part A Text Language Points,to increase, improve or add to something; to be one of the causes of something e.g. This book contributes little to our understanding of the subject. 此书对我们了解这门学科无所助益。 Air pollution contributes to respiratory diseases. 空气污染会引起呼吸道疾病。,Part A Text Language Points,v. to eat food quickly and make food or drink go down your throat and towards your stomach; to push or force somebody or something into a small space e.g. I managed to cram down a few mouthfuls of food. 我好歹狼吞虎咽地吃了几口东西。 Jack crammed his clothes into the bag. 杰克把他的衣服塞进袋子里。,Part A Text Language Points,to become fatter and heavier, especially by the amount mentioned e.g. Rosies put on five kilos since she quit smoking. 罗琦戒烟以来体重已增加了5公斤。 He has put on weight during the last two months. 他上两个月里体重增加了。,Part A Text Language Points,Note: The term is the average amount of weight gained during a students stay at a college or university. Undergraduate students typically gain up to fifteen pounds during the first year. The expression is commonly used in the United States and Canada. The purported causes of this weight gain are increased alcohol intake and the consumption of fat and carbohydrate-rich cafeteria style food and fast food in university dormitories.

They have more calories for the volume of food and generally fewer nutrients.,Part A Text Language Points,v. to take or hold somebody or something suddenly; to have or take something quickly, especially because you are in a hurry e.g. Jim grabbed a cake from the plate. 吉姆从盘子里抓了一块蛋糕。 Lets grab a sandwich before we go. 咱们赶快吃个三明治就走吧。 I manage to grab a couple of hours sleep on the plane. 我在飞机上抓紧时间睡了两三个钟头。,Part A Text Language Points,Note: It is a Japanese noodle dish.
