By now, most people know they should be eating more vegetables. But are there ways to get more from the vegetables you already eat? A research shows that when it comes to vegetables, it’s not only how much we eat, but also how we prepare them, that decides the vitamins and other nutrients that enter our body.
Many studies show that people who eat lots of vegetables have less heart disease, and eye problems and even cancer. But raw vegetables are not always best. The researchers found that 198 Germans who eat raw food were short of lycopene. “For fruits and vegetables, sometimes a little bit of cooking can be helpful.”
A number of factors decide how the vegetables do good to people’s health, including where and how they were grown and stored. No single cooking way is best. Some nutrients are easily lost in cooking if they are cooked in different ways. For example, frying was the worst way to cook.
What cooked with the vegetables can also be important? When the vegetables were cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them.

Here are some tips for preventing weight gain and maintaining physical fitness：
Don't skip meals.Before you leave home，have a small，low-fat meal or snack.This may help to avoid getting too excited before delicious foods.
Control portions.Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” You should be most comfortable eating an amount of food about the size of your fist. Once you have your “tasting” serving，move away from the buffet(自助餐). Doing so will make it less tempting to be eating constantly as your appetite is inspired by the sight of food.
Begin with soup and fruit or vegetables. Fill up beforehand on water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full.
Stick to physical activity. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories.
Avoid high-fat foods. Dishes that look oily or creamy may have a large amount of fat. Choose lean meats. Fill your plate with salad and green vegetables. Use lemon juice instead of dessert or butter.

Oak leaf tea, acom coffee, and pine pollen syrup are just a few of the seasonal ingredients people can now get thanks to projects such as the Forage Box. This delivery service collects wild food very few people know about, and sends it to the subscribers monthly. In this way, everyone can surprise their loved ones with delicious meals.
“The flavors are big and bold that’s the point. The idea is to show there’s a lot more going on when nature gets to farm it,” said Jim Parum, creator of the Forage Box. Since he started the project, he spends his days foraging for ingredients in environments such as the countryside, forests and the coast. The idea of the Forage Box is not to send out meal boxes but new ingredients, so information about cooking these wild items is also offered in the boxes. Delicious and inspiring recipes can also be found on the company’s website.
Underlying this project is the belief that nature has a lot to offer and can provide us with much tastier and healthier ingredients than those in the supermarket. The project works well as people are looking for ways to deal with the challenge of climate change while living healthier lives.
In the past, organic food was only available in specialty health food stores, but now it has a much more mainstream (主流) following worldwide. In the United States alone, it reached 50 billion dollars in value in 2019, up from 13.26 billion in 2005. This shows growth of nearly 300 percent over this period.
Miles Irving, an international wild food expert, said, “For us, foraged food is a very powerful way to reconnect people with the land, and this provides all sorts of benefits to physical, mental, emotional and community health.”

A pair of eyes on the front of driverless vehicles could, according to the researchers, give people standing by the road a better idea of whether they’ve been seen. That’s one useful bit of information to have when it comes to determining the perfect moment to cross in front of oncoming traffic. “If the car is not looking at the pedestrian, this implies that the car does not recognize the pedestrian,” said one of the researchers. “Thus, pedestrians can judge that they should not cross the street, thereby avoiding potential traffic accidents.”
For the purposes of this study, the researchers used a car which seemed as if no one was inside. A pair of large, swiveling (旋转的) eyes on the front were controlled by researchers, but in the future could be controlled by the car’s AI on an actual self-driving vehicle.
To keep the 18 participants safe, experiments were conducted in virtual reality. The volunteers—nine men and nine women—were asked to decide whether or not to cross the road as the car approached. Four scenarios(方案) were tested in total; two when the car was fitted with eyes, and two when it wasn’t. The researchers measured how often people hesitated to cross when it was in fact safe to do so, and how often they chose to cross when it was dangerous. Overall, the presence of the eyes led to safer and smoother crossing experiences for the participants.
However, there was a gender split in the results. For men, the eyes only really helped in dangerous situations, warning them to pause when they might otherwise proceed. For women, the eyes boosted confidence by signaling it was safe to cross.

Interestingly, we know now that numerical（数值的）competence is present on almost every branch of the animal tree of life,” says Andreas Nieder, a neurobiologist from the University of Tuebingen. “Different groups of animals obviously developed this trait（特点）independently from others and that strongly indicates that it has to be of adaptive value.”
Honeybees, for instance, can remember the number of landmarks they pass when searching for food in order to find their way back to the hive. The last common ancestor between honeybees and primates lived about 600 million years ago. But still, they evolved numerical competence that, in many respects, is comparable to vertebrate（脊椎动物的）numerical competence. Also, for example, male frogs sing “advertisement” calls to attract females. The females, listening for the complexity of their calls, choose the male that sings the most calls.
Wolves are more likely to hunt successfully if they have the right number of wolves in their pack for the size of their prey（猎物）: With prey like deer, only around six to eight wolves are needed, while hunting wild ox requires a pack of nine to thirteen. Their prey also uses this concept to protect themselves from predators — deer tend to live in large herds to reduce the chance of any individual becoming prey. So obviously they are assessing the number of individuals in their groups for their everyday life situations.
Despite these many examples of numerical competence in animals, this subject has not gotten many first-hand studies. “Many of these behavioral findings in the wild have usually been collected as by-products or accidental findings of other research questions,” says Nieder. He argues that more research needs to be done to fully understand the numerical competence.

【推荐1】Experts from MIT have found means to incorporate (加入) electronic sensors into fabrics, which can help to create shirts or other garments that could be used to monitor vital signs such as temperature and heart rate. The sensor-embedded garments can be customized to fit close to the body of the person wearing them.
“We can have electronic parts or lab-made electronics embedded within the textiles that we wear every day, creating comfortable garments,” says Dagdeviren, an professor at MIT. His group set out to create garments more similar to the clothes we normally wear, using a fabric that has removable electronic sensors in it.
“In our case, the textile is not electrically functional. It’s just a passive element of our garment so that you can wear the devices comfortably during your daily activities,” Dagdeviren says. “Our main goal was to measure the physical activity of the body all from the same body part, without requiring any fixture or any tape.”
The electronic sensors consist of long flexible strips. These channels have small openings that allow the sensors to be exposed to the skin. For this study, the researchers designed a shirt with 30 temperature sensors and an accelerometer(加速度计) that can measure the wearer’s movement, heart rate, and breathing rate. The garment can then transmit this data wirelessly to a smartphone.
This kind of sensing could be useful for personalized telemedicine, allowing doctors to remotely monitor patients. “You don’t need to go to the doctor or do a video call,” Dagdeviren says. “Through this kind of data collection, I think doctors can make better assessments and help their patients in a better way.”
Last summer, several of the researchers spent time at a factory in Shenzhen, China, to experiment with mass-producing the material used for the garments. “From the outside it looks like a normal T-shirt, but from the inside, you can see the electronic parts which are touching your skin,” Dagdeviren says.

【推荐2】The national movement to get rid of plastic bags has been gaining steam — with over 240 cities and counties passing laws that ban (明令禁止) or tax them since 2007 in the US. But these bans may be hurting the environment more than helping it.
University of Sydney economist Rebecca Taylor and her colleagues compared cities with the bans with those without them about the use of bags. For six months, they spent weekends in grocery stores recording the types of bags people carried out.
Taylor found these bag bans did what they were supposed to: People in the cities with the bans used fewer plastic bags. But people who used to reuse their shopping bags for other purposes, like picking up dog waste, still needed bags. “What I found was that sales of garbage bags actually grew sharply after plastic grocery bags were banned,” she says.
Garbage bags are thick and use more plastic than typical shopping bags. “About 30 percent of the plastic that was reduced by the ban comes back in the form of thicker garbage bags,” Taylor says. On top of that, cities that banned plastic bags saw a surge in the use of paper bags, which she thinks resulted in about 80 million pounds of extra paper garbage per year.
A bunch of studies find that paper bags are actually worse for the environment. They require cutting down and processing trees, which needs lots of water, toxic chemicals and fuel. While paper is biodegradable and avoids some of the problems of plastic, Taylor says, the huge increase of paper means banning plastic shopping bags increases greenhouse gas emissions.
The Danish government recently did a study that took into consideration environmental impacts beyond simply greenhouse gas emissions, including the use of water, damage to ecosystems and air pollution. These factors make cloth bags even worse. They estimate you would have to use an organic cotton bag 20,000 times more than a plastic grocery bag to make using it better for the environment.

【推荐3】Every year, thousands of new high school graduates pack their bags, move to new cities, and sign papers accepting loans, the money borrowed from a bank or lenders etc, which they might not be able to pay back. Without proper education on personal finance, especially as it relates to paying for college, young adults are guided into improper loan plans that result in years of debt after graduation. In order to set students up to succeed financially, it is important to educate students and parents on their financial options before school in the fall. The best way to support families heading for college is to require that every high school student take a personal finance class before graduation. This will help smooth the transition into adulthood.
The average student takes out at least one loan to cover the costs of their education each year. In 2014 the average student graduating from college carried a negative balance of about $20,000 in debt, which often spread over multiple lenders. Upon graduation, students rarely know exactly how much money they owe, and even though they are in the state of being unable to pay their debts, they cannot wipe out student loans. These students spend much of their adult lives paying off the gradual increasing debts.
A personal finance course would teach students how to manage their income and expenditures, while helping to significantly reduce the amount of debt students carry into adulthood. By teaching students how to save money and live within their means, this course will provide the next generation with a foundation to progress financially. Students choosing to get a job straight out of high school would also benefit from finance education for these very reasons. With education on how to manage their finances, all young people will have the knowledge to make healthy decisions, leading them to improve good credit and purchase needed items like cars and homes with skill and confidence.
While not every young person makes financial mistakes, those who do can face years of difficulty trying to get their finances back under control. Rather than help them through these hard times when they happen, we should try to prevent them from happening at all. Making the completion of personal finance coursework a requirement for graduation would ensure that young people are at least aware of the basics of preserving a financial stability.
1. After graduation from college, many young people ______.| A．struggle to support their families |
