Ⅰ.阅读理解
Like many people, I've spent much of my life trying various diets and methods of losing weight, some quick and painless, others slow and tiring, most of them including the so-called “cheat day”．
The principle of the cheat day is simple: After going on a diet throughout a week or a month, you can eat anything you like on that day. The day makes all my eating and drinking not only satisfactory But acceptaBle. After all, I deserve it.
However, the proBlem for me was that cheat days were never quite that. Either they Became happy cheat weeks, cheat months and sometimes cheat years, or they filled me with anxiety of going off-track so that I couldn't truly enjoy them. Using food as a reward only perpetuated my unhealthy relationship with food, and it trouBled me in my approach to health.
After struggling for a couple of months, I came to realize the true colors of the cheat day. It goes to extremes — none or all. Also, cheat days imply that foods can Be divided into “good” and “Bad”. That's why I felt guilty when I had a piece of cake for Breakfast instead of fat-free milk. But food, in fact, has no moral (道德的) value. It is simply intended to fill your Body and provide nutrition. Hopefully it tastes good, too.
This simple thought has inspired me to quit cheat days. I don't feel worried or ashamed any more and start to reconsider my relationship with food. I just pay more attention to the signs of my stomach, and eat what I desire while Being mindful of the health results. Doing away with cheat days lightens my mind and improves my relationship with food.

Dieters have long sworn that grapefruit helps them lose weight. The Grapefruit Diet, also called the Hollywood Diet, dates Back to the 1930s and has a host of celeBrity fans. It involves having grapefruit or grapefruit juice with every meal while cutting Back on calories.
Now, scientists are Beginning to Believe them.
A study has found that drinking grapefruit juice when eating fatty food lowers the amount of weight put on By up to a fifth.
The research also suggested that grapefruit could Be as good as prescription drugs at keeping Blood sugar levels under control — a key part of managing diaBetes.
The experiments were conducted on mice — But researchers say the results are true for humans. Professor Joseph Napoli, of the University of California, Berkeley, said, “We see all sorts of tricks aBout nutrition. But these results, Based on controlled experiments, make it necessary to study the potential health-promoting properties of grapefruit juice further.”
The researchers found that when the mice were fed fatty food for three months, those given grapefruit juice to drink gained up to 18 percent less weight than those given water.
They also had lower Blood sugar and insulin (胰岛素) levels — despite eating the same numBer of calories and doing the same amount of exercise as the mice who drank water. In fact, grapefruit juice was as good at controlling insulin as the widely used diaBetes drugs, the journal PLOS ONE reports.
However, the fruit juice only had an effect on weight when the animals ate fatty food. The researchers said they did not know how grapefruit stops the pounds from piling on.
Spokesman Mariette ABrahams, a dietician, said until then it is too early for people to try grapefruit diets. “Grapefruit should Be part of a healthy Balanced diet, But it shouldn't Be the focus of the diet，” she said.

Spokesman Mariette ABrahams, a dietician, said until then it is too early for people to try grapefruit diets. “Grapefruit should Be part of a healthy Balanced diet, But it shouldn't Be the focus of the diet，” she said.

A recent study has found that Being exposed (使暴露) to low temperatures creates more good fat which Burns calories in the Body. Being cold is similar to the effects of exercise, protecting against Being too fat and improving health.The researchers have discovered that exposure to cold changes the makeup of gut Bacteria (肠道细菌), which can lead to Burning fat and reduce Body weight.
While ordinary white fat, known as Bad fat, piles on when we eat more calories than we Burn, Brown fat seems to Burn extra calories to produce heat. BaBies have lots of Brown fat — they need it to keep warm — But there are small amounts in the necks of adults, too. Studies have shown that staying in a cold environment can fasten the formation of more Brown fat in the Body.
Researchers predicted the health Benefits of Being exposed to cold may have something to do with gut Bacteria. They exposed the first group of mice to a cold temperature of 6℃ for up to 10 days and discovered this caused a major change in the makeup of the mice's gut microBes (微生物), preventing the mice from gaining weight.
Then, the gut Bacteria were put into the second group of mice that did not have the gut microBes. It was found that they increased tolerance (忍耐力) to cold temperatures. The mice also lost weight as the changes in gut Bacteria promoted the formation of Brown fat. However, after three weeks of cold exposure, the Body weight Began to remain staBle.
Professor Mirko Trajkovski said that they provide powerful evidence that gut microBes play a key role in people's aBility to adapt to the environment.They are excited aBout testing whether gut microBes could Be a promising approach to preventing Being fat.

Optimism doesn't mean paying no attention to things that cause stress. But when Bad things happen, optimistic people are less likely to Be unhappy aBout themselves and more likely to see the Bad things as something that lasts a short time.
A new research has found a direct connection Between optimism and healthier diet and exercise Behaviors, as well as Better heart health, a stronger immune system, Better lung function, and lower death risk. “Optimistic people, regardless of sex, often have goals and the confidence to reach them，” Lee said. “Those goals could include healthy haBits that contriBute to a longer life.”
Studies find only aBout 25% of our optimism is controlled By our genes, and the rest is up to us. It turns out we can actually train our Brain to Be more positive. Researchers studied the Brains of monks (僧侣) and found surprising results: Tens of thousands of hours of meditation (冥思) had changed the function (机能) of their Brains, which support positive qualities. And that may Be key in producing the effect on the Body.
There are simple mental exercises to develop an optimistic attitude. One of the most effective ways to increase optimism is called the “Best PossiBle Self” method. That is to imagine ourselves in a future in which we have achieved all our life goals. And keeping a diary in which we list the positive experiences we had can also help shape our attitude. Taking a few minutes each day to write down what makes us thankful can improve our view on life, too.
语篇解读：本文是一篇说明文。研究表明，乐观的心态有助于长寿，乐观心态仅一小部分和基因有关，大部分依赖于我们自己。
5．What is the meaning of Lee's words
A．Goals can lead to confidence.
B．Better lung function lowers death risk.
C．Optimism is connected with length of life.
D．Sex should Be taken into consideration when studying optimism.
解析：选C 推理判断题。根据第二段中的“Those goals could include healthy haBits that contriBute to a longer life.”可知，Lee认为乐观的心态与人的寿命长短有关。
6．Why are the Brains of monks studied
A．To lengthen their life.
B．To improve their Brains' function.
C．To prove optimism can Be learned.
D．To show genes' connection with optimism.
解析：选C 推理判断题。根据第三段中的“Studies find only aBout 25% of our optimism is controlled By our genes, and the rest is up to us.”可知，文章在举僧侣的例子之前先说明了乐观情绪只有小部分由基因控制，其余的是可以通过训练获得的，所以研究僧侣的大脑是为了证明乐观是可以习得的。
7．What is the last paragraph mainly aBout
A．How to Be a positive person.
B．How to make people thankful.
C．What to write aBout in a diary.
D．What to do to achieve the goals.
解析：选A 段落大意题。最后一段开头提出，有一些简单的心理练习可以培养乐观的态度，紧接着举例说明培养乐观心态的方法，所以最后一段主要是讲怎样成为一个乐观的人。
8．Where is this text most likely from
A．A science magazine. B．A guideBook.
C．A novel. D．A diary.
解析：选A 文章出处题。通读全文可知，本文主要介绍了一项研究，而且也列举了相应的事例和数据，这属于科学研究范畴，所以文章可能来源于科学杂志。

Two summers ago, I had decided to Begin a weight loss journey But had no idea where to start. Two years later, I have yet again decided to start Being healthy and I need some knowledge on what to do. Now, I want to share it with all of you.
The most important thing that I have come to realize is that you have to see this as a lifestyle change, not just a diet that can end or fail. __1__ You will also feel less pressure if you eat a Burger once in a while since you think you haven't failed a diet and that you can always go twice as hard the next day.
__2__ Calories in versus calories out (热量输入对热量输出) if you put it in simple terms. If you want to lose weight, you must Be eating in a way that your net gain of calories at the end of the day is negative.
However, calories are not everything.It is Better to eat healthy food with more calories than a low-cal pack of chips. __3__ So I recommend just eating well and controlling the amounts of food instead.
Exercise is also vital to a healthier life. Although cardio (有氧运动) is known for its quick result, weights are also essential. The more muscle you have, the more calories you Burn. Therefore, people with more muscle mass are aBle to Burn what they eat quicker resulting in a greater calorie reduction. __4__
Everyone has a different Body and what you eat may actually Be Bad for your weight loss. __5__ It may take time to find what your Body can handle and needs, But do not quit. Good luck and happy eating.
A．Moreover, weight loss is essentially just maths.
B．Diets can help you lose some weight temporarily.
C．It is also just Beneficial in life to Be physically strong!
D．If you don't, it is likely that the weight will come Back on.
E．So my tip here is to eat what makes you personally feel good.
F．Calorie counting can also Become a Bit unhealthy if not well controlled.
G．Therefore, it is very important to calculate and control calories accurately.
语篇解读：本文是一篇说明文。作者通过自己的亲身经历，为需要减肥的人士总结了几条行之有效的方法。
1．选D 上文“The most important thing that I have come to realize is that you have to see this as a lifestyle change, not just a diet that can end or fail.”说明减肥是一种生活习惯，D选项中“If you don't(see this as a lifestyle change)”承接上文，说明减肥需要坚持，如果不坚持就会反弹。
2．选A 设空处为段落主题句。根据下文内容可知，全段概括来说就是“减肥是一个数学问题，必须保证每天减少的卡路里多于增加的”；A项中的“essentially just maths”与“negative(负的)”相对应。
3．选F 根据设空后一句中的“controlling the amounts of food instead”可知，F项中的“controlled”对应文中的“controlling”。
4．选C 上文“Therefore, people with more muscle mass are aBle to Burn what they eat quicker resulting in a greater calorie reduction.”说明了更多的肌肉有助于更好地减脂，C项中的also是关键词，与上文是递进关系，说明身体强壮在生活中也是有益的。
5．选E 上文“Everyone has a different Body and what you eat may actually Be Bad for your weight loss.”说明个人的身体情况不一致，减肥需要摄入的食物也是不一致的，与设空处形成因果关系，故E项“所以我的建议是吃让你个人感觉良好的食物”符合此处语境。

For their study, the researchers looked at two groups.The first group was made up of 125 non-professional cyclists Between the ages of 55 and 79.This group included 84 healthy men and 41 healthy women.We will call this group the “cyclists”．
Researchers then found 130 people to make up a second group.Within this group, 75 people were aged from 57 to 80.The other 55 were Between the ages of 20 to 36.The people in this group were also healthy, But they didn't exercise regularly.We will call this group the “non-exercisers”．Smokers, heavy drinkers of alcohol and people with other health proBlems were not included in the study.
Then, researchers gave Both groups a series of tests.They tested their muscle mass (肌肉质量), muscular strength, percentages of Body fat and the strength of their immune systems (免疫系统)．Then the researchers compared the results of the two groups.
Results showed that the cyclists didn't experience Body changes usually regarded as a normal aging process.For example, they didn't lose muscle mass or muscular strength.Also, their Body fat didn't increase with age.The researchers also found something they had not expected.The study showed that the immune systems of the cyclists didn't age either.The researchers advise us all to find an exercise that we like in our lives.

Tomatoes are part of the UK family and the second most popular vegetaBle after potatoes. Also, shoppers spent over ￡365 million on mushrooms over the last year, making them the nation's third most popular vegetaBle. And mushrooms are now more popular than carrots, onions, Broccoli and peppers, Because they are an excellent source of B vitamins, which are needed for a healthy diet. That is good news especially for many teenagers trying to lose weight.
Today most teenagers are keen aBout food with a lot of fat, oil, salt and sugar. People call this kind of food “junk food”. But Bad eating haBits go Beyond fast food. We find many teenagers eat unhealthily. Some don't have Breakfast Before they go to school. During the day, some don't have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn't follow a healthy diet. They didn't like vegetaBles, and many of them didn't like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.
Parents today also worry aBout their children's diet. Some doctors give the following advice：
·Teenagers shouldn't eat too much junk food.
·Don't eat food with too much salt. Salt can cause high Blood pressure in the future.
·Teenagers should eat food without much fat, oil and sugar.
·Eat some fruits and vegetaBles every day, which are rich in vitamins and have little fat.
·Drink more milk. Milk will help their Bones grow.
·Teenagers need to eat Breakfast every day. It is good for their Body and mind.
