Calorie(卡路里)counts are everywhere. They appear on restaurant menus, milk boxes and bags of baby carrots. Grocery stores display lots of foods packaged with bright and colorful “low-calorie” claims.
A calorie is the measure of stored energy in something---energy that can be released as heat when burned. The term calorie on food labels is short for kilocalorie. A kilocalorie is the amount of energy it takes to raise the temperature of one kilogram of water by 1 degree Celsius. But what does boiling water have to do with your body’s release of energy from food? After all, your body doesn’t start boiling after eating. It does, however, chemically break down food into sugars. The body then releases the energy to fuel processes and activities throughout each hour of the day.
Food contains three main types of nutrients that deliver energy: fats, proteins and carbs(碳水化合物). A process called metabolism(新陈代谢) first cuts these into small pieces; Proteins break down into amino acids(氨基酸), fats into fatty acids and carbs into simple sugars. Then, the body uses oxygen to break down these materials to release heat.
Most of this energy goes toward powering the heart, lungs, brain and other vital processes. Exercise and other activities also use energy. If energy-rich nutrients aren’t used right away, your body will hoard them---first in the liver(肝脏), and then later as body fat.
In general, someone should eat the same amount of energy each day as his or her body will use. If the balance is off, they will win lose or gain weight. It’s very easy to eat more calories than the body needs. Having two 200-calorie donuts in addition to regular meals could easily put teens over their daily needs. At the same time, it’s nearly impossible to balance overeating with extra exercise. Running a mile burns just 100 calories. Knowing how many calories are in the food we eat can help keep the energy in and out balanced.

【推荐1】The Chinese and Western eating habits are different. In the west, everyone has his or her own plate of food. In China,the dishes are placed on the table and everybody shares. It is always polite to let guests or elderly people at the table taste every dish first.
Though there are no strict rules on how to set chopsticks and spoons,there are some things you should never do during a Chinese dinner.
Firstly,and the most importantly, don’t put your chopsticks upright in the rice bowl. The reason for this is that when people die, family members give them a bowl of rice with a pair of chopsticks upright. So if you put your chopsticks in the rice bowl like that, it seems you want someone at the table to die.
Make sure the spout (喷口) of the teapot is not facing anyone as this is impolite. The spout should always face where nobody is sitting. Don’t knock on your bowl with your chopsticks. Beggars knock on their bowls, so this is not polite, especially when you eat in a friend’s home.
Though young children are not allowed to drink any wine, you can still say “Ganbei” and drink to the health of your grandparents and parents. This is sure to please them.

【推荐2】Why do Chinese people love hot pot so much? As the winter months are coming in, more and more people are sitting around a table enjoying this kind of traditional meal. I find myself wondering what it is about this traditional meal, which has existed for more than 1,000 years. What makes it a Chinese food favorite? It seems that the answer lies beyond the dish itself.
Hot pot isn’t just designed to keep you warm during the cold months; it’s also a social experience. It’s a “theater” cooked food that turns a meal into an event. There is a lot of fun for everyone to have in adding some foods to the hot pot.
Hot pot is eaten over two to three hours. For this reason, it is often considered an evening’s entertainment, and a time to spend with friends and families. However, many Westerners would be unhappy by the idea of other people sticking chopsticks in their food. When we come to eat at the table in the UK, we often have our own shares, although the experience is still a social one.
A similar experience to the hot pot can be found in Korean barbecue restaurants, which let you cook your own meat. This allows people to have their meat done however they want.
For most Westerners, the idea of going to a restaurant to cook their own food is very strange. But having a go, I find it’s now one of my favorite meals in Beijing. The steam from the pot left my clothes smelling of food when I got home, but perhaps this was also part of the experience. When the cold wind is blowing outside, I am sitting around with my good friends, eating and drinking. For me it’s like a dinner party where my taste buds(味蕾)and my appetite are equally satisfied in the warm company of friends.
1. What is the main reason why hot pot is popular in China?A.It has a history of over 1,000 years. | B.It serves people with many kinds of foods. |

A.More than four hours. | B.Over one hour. |

【推荐3】Most French people eat dinner at 8 pm or later. Some French families, especially if they do not have young children, may start dinner as late as 9 pm or 9:30 pm. The first time I went to France, I was confused that my host family hadn’t had dinner by 7 pm yet. “Are they going to skip dinner?” I wondered.
It’s not clear to me why French people eat so late. Alysa Salzberg, a French writer, guesses that the later meal time develops from typical French working hours. “French people eat late because most standard job hours are 9 or 10 to 6 instead of 9 to 5,” Alysa explains. “So, by the time everyone gets home and a meal is prepared, it’s about 8 pm.”
French people usually eat a smaller dinner, such as soup or salad with bread and dessert. Considering French people famously don’t snack, they must survive a long break between lunch and dinner. The solution is that lunch is the biggest meal of the day. Americans and people from other countries may have a simple sandwich for lunch, but French lunches are typically more considerable. I remember having a huge lunch at the host school with other French students last month. The lunch came with salad, bread, a main dish, cheese and a yogurt. It seemed like too much food the first time I saw it.
In addition, French people never eat on the way. It’s unusual to see French people eating a cheeseburger from a McDonald’s while sitting in their cars. I don’t remember seeing French people eating while walking in the street or on the subway in Paris either. French people consider it important to sit down at a table to eat and even eat a hamburger with a knife and fork.
1. Why do the French eat dinner late in Alysa Salzberg’s opinion?A.They have a big lunch. |
B.Dinner is less important to them. |
C.Dinner dishes take a long time to cook. |
D.They get off work late. |
A.simple | B.plentiful | C.expensive | D.delicious |
A.Cars play an important role in French life. |
B.Fast food is not popular in France. |
C.The French pay great attention to eating manners. |
D.Eating in public places is not allowed in France. |

【推荐1】As an international fresher arriving in Dublin for the first time last autumn, I was certain I had missed crucial aspects of Dublin’s social and cultural scene due to Covid-19. Therefore, it can be difficult to get a real sense of Dublin’s culture. Yet, one has emerged from this chaos: donuts.
Donuts has been taking over Dublin since at least 2017. Since then, the obsession(痴迷) has grown. Though the lockdown has certainly set in, we can still rely on meeting up with someone from another household, which is a sure way to get yourself out and get a snack in at the same time. As many of us are feeling isolated and stressed, it can be a good idea to get out and talk to someone who might also be struggling. Plus, doesn’t any exercise sound more appealing with baked goods involved?
A personal favourite of mine is Offbeat Donuts. They offer classic donuts such as those of the jam-filled, or sprinkle-topped variety, and also cater to(迎合) more adventurous tastes. Offbeat Donuts competes with The Rolling Donut, an older business originated from a small but popular newsstand on O’Connell Street. It offers a similar experience to Offbeat with donuts related in flavour. For the vegan doughnut lovers, however, The Rolling Donut is an obvious winner. It offers a broad selection of nine different vegan(素食主义者) donuts in comparison to Offbeat’s range of three. However, both have their advantages, as Offbeat is located just a five minute walk from college and offers a 10% student discount. The Rolling Donut, on the other hand, is not only on O’Connell Street, but there is also another next to St. Stephen’s Green, a perfect spot for walking around while sinking into the treat.
While the donut shops really give you the proper experience, there are many other donut options. Whether you’re hunting for a recreational donut or an emergency one, Dublin is certainly the place to be. Regardless of your preference, this city has what it takes. And who knows? With the city likely to be reopened in the coming months, Dublin’s donut shops won’t be the only place packed with customers.
1. What can we know from the passage?A.Donuts first appeared in Dublin 5 years ago. |
B.Offbeat Donuts favours the novelty seeker. |
C.One of the author’s favourite donut shops is next to a perfect spot. |
D.The most people can be found in Dublin’s donut shops. |

【推荐2】We all know a picky(挑剔的)eater or two. Maybe you have that one friend who refuses to step foot in a sushi restaurant even though she’s never tried it. Or the one who turns her nose up at anything green.
Experts suggest your DNA and upbringing are to blame for your picky eating habits. A group in Finland looked at what we call food neophobia, which means "fear of the new", and found there is some genetic basis for this. But neophobia can be greatly influenced by the surroundings. Parents unwilling to try anything new will expose(暴露)their kids to fewer new food.
People less adventurous may be more unlikely to try new foods. It’s normal for children to go through a picky stage when they’re toddlers, maybe two or three years old, and that makes sense evolutionarily. (When our ancestors first tried new foods, they had to be cautious to avoid being poisoned.) But as we get older, if we continue to avoid new food, pickiness can last.
For those who are simply picky, certain social situations like cocktail parties with all those foods full of mystery ingredients can cause anxiety. They’re often sort of embarrassed to admit that they eat like a child, so they will just say: "My stomach’s upset. " or "I had a late lunch. ".
Your taste buds can change over time, but that requires taking a chance on new foods. But to be less picky, you definitely have to be determined. The most common reason for wanting to change is social.
Expanding your eating horizons can make everything from a party to a vacation easier and more enjoyable.

When he was a boy , Watson stayed on a farm. .He loved to see the animals. He said that they gave so much to people. And all the animals were so friendly. Then , one day , he saw a man killing a pig . He was very sad. . From then on, Watson decided that he would never again eat meat . Twenty years later he decided that he wouldn’t eat anything from animals, such as milk, cheese or eggs. He became vegan (素食主义者).
Watson formed a group called “The Vegan Society”. In its newspaper, The Vegan Society thought it was terrible and wrong to eat food from animals. At first, there were not many people who agreed with him . They thought it was crazy to do
People become vegans for many reasons. Watson and his friend stopped eating because they loved animals. They believed that it was wrong to hurt another living thing .
Now, people also become vegans for environmental reasons. Keeping animals takes a lot of resources(资源), including water and food. Also, in some places, people are cutting down trees to create more land for cows. By avoiding food from animals, vegans hope to protect these forest areas.
Finally, just like Watson, some people believe that being a vegan is healthier. They believe that food from animals causes heart problems, a high body weight and many other health problems.
