With more and more people having a longer life in the world, people are eager to know what to do and what not to do.
It is well know that women live longer on average than men — and some researchers claim this is because they are better at visiting their doctor and voicing any concerns about their health, rather than sticking their heads in the sand.
Not smoking, not being overweight and taking sufficient exercise keep your heart and blood vessels healthy for longer — and all that is good for your brain, too.
One popular theory about aging concerns the damage caused to the tissues in our bodies by “free radicals (自由基)”. Our immune system makes these free radicals ineffective using antioxidant (抗氧化剂) nutrients such as vitamins A and C, and the theory is that a diet high in such “antioxidants” will help you hold back the the years. In fact, though there is no doubt among scientists that free radicals harm the body, there is no hard proof that aging is caused simply by a lack of sufficient antioxidants in our bodies or our food.
Another theory growing in popularity holds that we can stay alive longer by eating less, for an experiment concluded mice live longer when fed 30 percent fewer calories. Though the beneficial effect has since been found in other species, including fruit flies, what we really want to know is how this applies to humans. The answer may be found in long-term experiments in the U.S. using rhesus monkeys, which are closely related to us in evolutionary terms. However, though the aging process is slower in those animals, monkeys on the calorie restriction group do not appear to live longer.

To make matters worse, most young people get news from social media sites where facts are mixed with rumors (谣言), half-truths and complete lies. This has led to young people becoming confused. In the latest PISA, which tested 15-year-olds worldwide on academic subjects, fewer than one in ten of the examinees were reported to be able to recognize fact from opinion. A Stanford University study showed that students at all levels of education could not tell teal news from fake news. In one instance, 80 percent thought that a paid advertisement was a real news story.
Fake news is spread by people who have a prejudice (偏见). They want to influence public opinion either for or against something or someone. It is important, then, for young people to recognize when they are being used and to be doubtful about online information.
Traditional media, such as newspapers and television, are still the more credible sources of information. Reporters are professional trained to look for facts, and editors have the job of making sure those facts are correct. However, if you are getting most of your information online, you have to be your own editor. In that case, the first thing to do is to look at the writer of a post. Is this person known to be objective? Does the site where you read the post have a prejudice? Next, look for other sources from mainstream media to make sure the information. In other words, by putting on your truth boots you won’t be fooled into chasing lies.

Acid rain is now a familiar problem in the industrialized countries in Europe. Harmful gases like Sulphur dioxide and nitrogen oxide are produced by power stations and cars.
Acid rain is also capable of dissolving some rocks and buildings made of soft rock, such as limestone, are particularly badly affected. The acid rain attacks the rock, and so carvings and statues are worn away more quickly.
The acid rain is said to be caused by pollution from oil wells in the Gulf of Mexico. Car exhaust gases are also a problem. Local volcanic eruption make the problem even worse. Nevertheless, with enough money and effort, researchers say that many of the problems could be solved and the rate of dissolving reduced.
Mexico’s current lack of funds is also partly due to oil. The country has rich oil field and a few years ago, when oil was expensive, Mexico was selling large quantities of oil to the USA and earning a lot of money. The government was therefore able to borrow huge sums of money from banks around the world, thinking they would have no problem repaying their debts. However, the price of oil then dropped, and Mexico has been left owing enormous sums of money and with not enough income from oil sales to pay back the loans.
A.However, the Mexican government does not have enough money to do the work, and needs to spend what money it has on the Mexican people. |
B.That is enough to have caused some of the ancient carvings to become seriously damaged already. |
C.So unless the price of rises, it is unlikely that Mexican will be able to afford to clean up the pollution and save its Mayan ruins from destruction. |
D.These measures would reduce the pollution, but would not stop it completely. |
E.The problem, however, is not a European one. |
F.They dissolve in rainwater and this makes acid rain, which damages trees, rivers and streams. |
【推荐3】Positive Body Image Isn’t Enough
Body image as a construct focuses on our relationship with what our bodies look like. Most research in the field that’s been conducted with adolescent girls has focused on negative body image and its association with things like body dissatisfaction and eating disorders.
To fulfill this goal, we need to find ways to promote positive embodiment — that is, healthy ways of subjectively experiencing one’s body in the world that go above and beyond the way we look to the outside world.
1. Promote mindful self-care. In today’s “selfie” culture, where it seems like everything is about appearance, how do we help teens focus on the subjective, lived-in experiences in their bodies? One way is to promote mindful self-care — defined by Cook-Cottone (2015) as behaviors that cultivate an active appreciation for, and engagement with, the body. So, things that promote mind-body connection, like mindfulness, art, and the physical care of the body.
2.
3. Look at the social context. Positive embodiment doesn’t develop on its own. Teens are under pressure from all directions, including peers, social media, and parents.
A.In promoting these activities, we can encourage teens to focus on how they feel from within when engaged in these pursuits — rather than what they looked like while doing them. |
B.As such, we can model ways of engaging in activities that promote positive embodiment and encourage girls to surround themselves with peers who do the same. |
C.Although body image plays a role in having positive embodiment, the two don’t always go hand-in-hand. |
D.In recent years, however, there has been a movement toward focusing on positive body image. |
E.Be confident of body image. |
F.Focus on body functionality. |
【推荐1】Junk food is everywhere. We’re eating way too much of it. Most of us know what we’re doing and yet we do it anyway.
So here’s a suggestion offered by two researchers at the Rand Corporation: Why not take a lesson from alcohol control policies and apply them to where food is sold and how it’s displayed?
“Many policy measures to control obesity (肥胖症) assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods,” note the two researchers.
“In contrast,” the researchers continue, “many regulations that don’t assume people make rational choices have been successfully applied to control alcohol, a substance - like food - of which immoderate (过度的) consumption leads to serious health problems.”
The research references studies of people’s behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:
Density restrictions: licenses to sell alcohol aren’t handed out unplanned to all comers but are allotted (分配) based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.
Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren’t primarily food stores?
Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can’t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they’re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.

C.Drinking strong alcohol can cause social problems. |
D.Easy access leads to customer’ over-consumption. |
【推荐2】Nisha Pradhan is worried. The recent college graduate just turns 21 and plans to live on her own. But she’s afraid she won’t be able to stay safe. That’s because she isn’t able to smell.
Back home, her family do her smelling for her. She’s moved in with them for now, but she’s looking for a place of her own. “Now that I’m searching for ways or place to live as an independent person, I find that the sense of smell is important to how we live our lives,” Pradhan says.
She says when she was a child she liked to eat and ate a lot. But there came a point where she lost interest in food.
“One of the first things that people notice whenever they have a smell problem is that food doesn’t taste right any more,” says Beverly Cowart, a researcher. That’s because eating and smell go hand in hand. How food tastes often rely on what we smell. “When you lose your sense of smell, your whole sense of food flavors changed and reduced,” Cowart says, “You can still taste the basic tastes. What you’re missing are the small distinctions.”
“When I go out to eat I have often found that food is very tasteless to me. I never feel full,” she says. “I think a lot of us today like to pretend to be food lovers and we all like to talk about ‘Oh, I think this could use a little bit more flavor,’ or ‘I think this has a hint of meat,’ I can’t really participate in those conversations,” she says.
Pradam thinks her smell loss also may have affected her memory. Pradhan may be on to something, according to biologist Paul Moore. “When smell signals come in, you feel about them first. And then you think about it and then the memory is laid down. So without the feel part, the thinking about its part doesn’t come And that means no new smell memory gets created.”
1. What is true about Pradhan?A.She has had no sense of smell since she was born. |
B.She suffers from loss of appetite through lack of smell sense. |
C.She has something wrong with her stomach. |
D.She is looking for a roommate to share the cost. |
A.People with a smell problem have no food tastes. |
B.Different food tastes the same for people of smell loss. |
C.Lack of smell sense makes eating a dull experience. |
D.People feel hungry easily for lack of smell sense. |
A.feels left out sometimes | B.often has a good appetite |
C.pretends to have good smell sense | D.has a sense of being full quickly |
A.Pradhan may be right. | B.Pradhan may be foolish. |
