1 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

2 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

3 . Have you ever received a gift that was so clearly, not your taste that you wondered if perhaps it had been handed to you by mistake? Worse, have you ever given a present and watched your friend look as though she had opened the wrong box? Maybe she responded with a polite “Why, thank you,” but you knew you had missed the mark. Why do presents sometimes go wrong? And what do your choices (good and bad) reflect about your personal qualities?

Choosing the right gift is an art, I believe. It calls for empathy—the ability to put yourself into someone else’s head and heart.We’re all able to do this; in fact, we’re born with a kind of natural empathy.After the earliest period of childhood, however, it needs to be reinforced (加强) —by our parents, teachers, friends. When it isn’t, we’re not able to understand other people’s feelings as sharply.This can show in the gifts we select, and so can many other emotional(情感的) qualities.

Think back to the presents you’ve given over the past year, the time and effort you put into your selection, how much you spent, your thoughts while you were shopping, and your feelings when the receiver opened the package.Keep in mind that what you choose displays your inner world.(Of course, you may express yourself differently with different friends, relatives, and other people you know.)

We live in a society where exchanging presents is an important part of communication.Ignoring the tradition won’t make it go away.If you really dislike such a tradition, tell your friends ahead of time.

5 . The Amazon rainforest is as undisturbed a place as most people can imagine, but even there, the effects of a changing climate are playing out. Now, research suggests that many of the region’s most sensitive bird species are starting to evolve in response to warming.

Birds are often considered sentinel (哨兵) species — meaning that they indicate the overall health of an ecosystem — so scientists are particularly interested in how they’re responding to climate change. In general, the news has not been good. For instance, a 2019 report by the National Audubon Society found that more than two-thirds of North America’s bird species will be in danger of extinction by 2100 if warming trends continue on their current course.

For the new study, researchers collected the biggest database so far on the Amazon’s resident birds, representing 77 non-migratory species and lasting the 40 years from 1979 to 2019. During the study period, the average temperature in the region rose, while the amount of rainfall declined, making for a hotter, dryer climate overall. According to the report on November 12 in the journal Science Advances, 36 species have lost substantial weight, as much as 2 percent of their body weight per decade since 1980. Meanwhile, all the species showed some decrease in average body mass, while a third grew longer wings.

Because of the study’s long time series and large sample sizes, the authors were able to show the morphological (形态学的) effects of climate change on resident birds. However, the researchers themselves are unsure and wonder what advantage the wing length changes give the birds, but suppose smaller birds may have an easier time keeping cool. In general, smaller animals have a larger rate of surface area to body size, so they dissipate more heat faster than a bigger animal. Less available food, such as fruit or insects, in dryer weather might lead to smaller body size.

6 . Harper Lee (1926—2016) was an American novelist widely known for To Kill a Mockingbird (published in 1960), which won the 1961 Pulitzer Prize and has become a classic of modern American literature. The 1962 film adaptation starring Gregory Peck won three Academy Awards.

For decades, the book was Lee’s only major work of published fiction, but it was hugely influential for generations of U.S. readers. It has sold more than 10 million copies, and is one of the most widely taught novels in the U.S. schools. In 2007 she was awarded the Presidential Medal of Freedom for her contributions to literature.

Lee wanted to live a simple life and was never comfortable with the attention the novel won her, and she practically disappeared from public life after it appeared. The world, however, continued waiting for a new novel from her, and on occasion she suggested that she was working on another story.

In 2015, a book did come out. Go Set a Watchman was more of a first draft, featuring Scout, the young girl who was the main character of To Kill a Mockingbird. Go Set a Watchman tells a story of Scout as adult.

Though Lee moved to New York in 1949, she spent many years guarding her privacy (隐私) in Monroeville, which served as the clear inspiration for the setting in To Kill a Mockingbird.

In 2007, Lee suffered a stroke (中风), but recovered and later settled in Monroeville permanently to care for her sister, Alice, who died in 2014. She was said to eat breakfast every morning at the same fast-food spot, and was friendly with her neighbors. The countless Americans knew her only through her works, and they will undoubtedly miss her.

7 . The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important role in keeping you healthy.

Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it’s for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

Anyway, adding humor, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humor, laughter and play to make our life more active, more interesting and happier.

9 . Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.

There are four main kinds of blood. Most people are born with one of these four: Type A, Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.

Type O is the most common blood group. But the supplies of it available in hospitals and blood banks are usually limited. This is because of the high demand for it. Type O blood is used in emergencies when there is no time to identify the patient’s blood type.

Giving A, B or AB to someone with a different blood type, including O, can cause a bad reaction by the person’s defense system. Their immune system can reject the blood. This immune reaction can be deadly.

The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules (分子). These molecules are found on the surface of the cells. They are known as antigens (抗原), these antigens are found with Type A, B and AB blood but not with Type O.

More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes (酶). But large amounts of enzymes were required to make the change.

Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements and is not too costly, it will become a widely used life-saving tool to increase the supply of universal blood.

The most important thing to keep in mind when going into high school is to be yourself. Besides, I don’t know what your middle school was like, but high school teachers will not care about things such as how much homework you already have for one night. It’s best to just learn to deal with things and manage your time wisely so you can achieve everything you need to do.

I’m not going to lie. The first day is kind of frightening. But you’ll get used to it. Don’t be afraid of anyone; Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it’s really not bad at all. Don’t worry.

I think almost every kid feels both anxious and excited before their first day. You will probably love it. I know I did. You should join in some sports or activities that will make your high school experience more enjoyable. Good luck!

When I started high school I was really nervous and worried too, especially since I had been home schooled all through middle school and didn’t really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.
