【推荐1】Organic food is very popular. It is also expensive. Some organic food costs twice as much as nonorganic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money.
There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals, such as pesticides (杀虫剂). This makes sure that the products are natural.
Some people think “organic” means “locally grown”. At the beginning, this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren’t enough organic materials. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.
Is organic food more nutritious? This is part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals cause health problems, such as cancer. Many health experts disagree. Few studies prove that organic food prevents health problems. Health experts worry more about bacteria. These can come into contact with organic and non-organic food. Doctors recommend washing produce very carefully.
Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.

Covering an area of over 400 square meters with a total of 112 seats, the X Future Restaurant is a robot restaurant that opened in November 2018. The restaurant has amazed customers with its fully-automated (全自动的) technology, which covers every step of the dining experience, from ordering to cooking to serving the dishes and even taking payment.
Entering the restaurant, one can order dishes by simply scanning the QR codes on the table. There are over 40 choices of dishes. After taking the order, “robot cooks” prepare dishes using fixed time, temperature and ingredients designed by famous Chinese cooks.
“As the cooking is controlled by a computer system, the taste and quality of dishes can be good,” said Li Xiaokui, manager of the X Future Restaurant.
Robots also complete the delivery of dishes. Without following any designed route, the robot waiters serve meals thanks to automated driving technology, which helps each robot timely change its route when something is in the way.
These eye-catching technologies have received wide praise from customers. “The dishes taste surprisingly good. I couldn’t believe that they were made by robots, especially dishes that were difficult to cook.” one customer said. “The application of robots has increased our efficiency and cut down our costs,” Li said, “I think robot restaurants will develop fast and have a bright future.”

Frozen food lasts indefinitely. But does that mean the raw chicken you bought on sale and froze will taste as good a year from now as it will three weeks from now? No. You can cook up that chicken a year later and it won’t harm you, but its taste and texture will be diminished. The key is knowing when frozen food starts to lose quality.
Fruits and vegetables.
You can freeze most vegetables and non-citrus fruits for about 8 to 12 months, according to the National Center for Home Food Preservation. (You can freeze citrus, too, but you need to take some extra steps.) Vegetables will benefit from blanching（用沸水烫）before you freeze them.
●Ground beef, turkey, veal, pork and lamb: For best flavor and texture, these ground meats are best used within three or four months of being frozen.
●Steaks and chops: These cuts of beef, veal, lamb or pork can be frozen for six to 12 months before losing quality. Chops of these meats start to lose quality after four to six months.
●Poultry:
●Fish: For best quality, fatty fish (salmon, tuna) should be consumed within two to three months. Lean fish (cod, flounder) should be consumed within six months.
Soups, stews, chili and casseroles
Soups, stews chili and casseroles that have vegetables, meats, grains, pasta or cheese will keep their quality for two or three months in the freezer.
| A．Raw meat |
| B．General leftovers |
| C．Whole birds can keep their quality for up to a year |
| D．The point of that process is to stop the enzyme（酶）process |
| E．It’s still safe to eat, but it will have a lower quality taste and texture |

| G．There isn’t a magic number of days for each food, but there are general guidelines to follow |
【推荐1】Studies on the importance of sleep for health and the various effects of not having enough sleep have long been well-known. Being short of sleep can lead to poor memory and daytime sleepiness. It’s also been connected to diseases and weakens immune(免疫的)function. However, more than three-quarters of us fall asleep after 11pm and nearly a third stay up until 1am.
The concept(概念)of sleep procrastination was introduced in a 2014 study by Utrecht University in The Netherlands, which explained that it meant “failing to go to bed at the intended time, while nothing prevents a person from doing so”. If so, it will bring terrible results.
Studies have shown that “bedtime procrastination” is connected with a person’s working life during the day. “They feel out of control in their day life and the night is when they can be free,” says Dr Saliha Afridi. “It is full of things they ‘have to do’ rather than what they ‘want to do’. ” Studies have also found that increased working hours and the reduced leisure time may cause much stress and sleep procrastination. On occasion, people have trouble with feelings, concern and loneliness, so they were controlled by using social media, making them stay up late.
So how to avoid it? People should avoid thinking too much before bedtime and stay away from digital devices. Besides, taking a warm shower before bed and going to bed at the intended time are also important.

【推荐2】Last weekend, I said goodbye to another dear old friend. We had 12 fine years together, but our relationship was becoming dysfunctional(不正常的). Unwanted emissions and serious health problems were the final straw, leaving me with no choice but to make a trip to the knacker’s(收废汽车者的)yard.
I am now car-free for the first time in 20 years, and it feels strange. When I gave up meat, I did so mainly for environmental reasons, and I didn’t miss it at all. I would like to say the same about my car, but I can’t. It was first and foremost a financial decision: keeping the old car on the road was getting too expensive.
But doing the right thing for the wrong reasons is still doing the right thing — I now have a chance to rethink how I move myself and my family around, and can try to find a more environmentally friendly means of transport.
Going car-free is, I think, a lifestyle change that many of us are going to make over the next few years, as car ownership becomes increasingly unnecessary, expensive and socially unacceptable. However, it is easier said than done. Now my car is gone. I still need to get around. But how? I already cycle to work and use public transport when appropriate. But there are some occasions when a car seems to be the only way.
I won’t buy one: I have joined a car-share program and will use taxis more often. I will hire a car if I need to drive a long distance. But then I am still travelling in fossil-fuelled cars(燃油汽车), like when I quit meat and ended up eating more cheese. I fear I may have swapped one environmental problem for another.
I am also afraid to think about the ultimate fate of my car. I have just offloaded more than a ton of metal, plastic, rubber, fabric, electronics, oil and petrol that will end up in a landfill. There are millions of similar vehicles in the UK alone that will have to go somewhere.
Maybe I am overthinking it. According to Charlie Wilson, a climate scientist at the UK’s Tyndall Centre for Climate Change Research, getting rid of a private car is no doubt a positive step to reduce CO2 emissions.
He points to research by the OECD’s International Transport Forum. “They showed that moving from a private vehicle fleet(车队)to a shared vehicle fleet can greatly cut the number of vehicles you need to deliver the mobility that we need and want. If that vehicle fleet is electrified, you can also bring CO2 emissions close to zero.”
So in other words, just get rid of your car.

【推荐3】For several months, Cara has been working up the courage to ask her mother about what she saw on the Internet. Not long ago, the 11-year-old found out that her mother had been posting her photos in her blog, without her agreement, for much of her life. "There are pictures I don't like of myself. It would be an embarrassment(令人尴尬的事)if my friends see those photos online," she said. "Now I'm even worried anytime someone has a phone out around me. I'm afraid that my photos could be taken and posted somewhere."
Not all kids feel the same when finding out they've been living a life online. Some are happy. In the fourth grade, Nate searched his name and found that he was in a news report about his making a beautiful kite in his third-grade class. He was really happy with that and he decided to search online every few months, hoping to find other things about himself online.
"I was surprised, really surprised," he said. "It made me feel famous."
He even kept saying, "Oh, I'm in a news report online." Although his friends knew that, many of his friends refused to stay close to him.
Like most other kids, Cara and Nate grew up in a society rich with social media. While many kids may not yet have accounts(账户)themselves, their parents, schools, sports teams, and organizations have been building an online presence for them since their birth. According to a study from the Levin College of Law at the University of Florida, 92 percent of kids under the age of 2 already have their own life online.
"The blog posts are sure to follow the children into adulthood," says the study. "Therefore, we have to be careful about putting the children's personal information online."
