Cell phones:Is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia (白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ”said Carpenter.
But others believe these concerns are not justified. Dr Martha Linet, head of radiation epidemiology (流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ”said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs (电磁场) and illness—so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.

【推荐1】Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.
Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.
It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes curry or rich pasta sauces, which may please their partner. Women still have the strongest long-term influence over the couple’s diet and lifestyle, as they still have the traditional role of shopper and cook in most households.
The report, by Newcastle University’s Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.
The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner.
Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.
Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.
Report author and registered dietician Dr. Amelia Lake said, “The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration.”

Aside from the health benefits of laughter (which are numerous and significant), having a sense of humor about life’s difficulties can provide a way to bond with others, look at things in a different way, normalize your experience, and keep things from appearing too overwhelming or scary. Properly developed, a good sense of humor can keep people and relationships strong.
Studies show that having a smile on your face can make you feel better, and can lead you to actually feeling happier (rather than just looking happier). Even if the smile is fake, the benefits you will experience are real! Also, a fake smile leads readily to a genuine one. If you are able to put a smile on your face, the laughter will come more easily, and the stress will melt more easily.
If your situation seems ridiculously frustrating, recognize what can develop into humor in just how ridiculously frustrating and annoying it is. In your imagination, take the situation to an extreme that becomes even more ridiculous until you find yourself amused. For example, when you’re waiting in a long line at the store, you can imagine that hours pass, then days, visualizing yourself accepting visits from loved ones from your new home in this ultra-long line, holding your children’s birthday parties in aisle seven so you can be there to enjoy them...you get the picture.
Besides, find a friend with whom you can laugh also works! You can each share your frustrations, and laugh about them in the process. Even when your friend isn’t there, you can feel less stressed by thinking about the retelling that will come later.
You can have a "most annoying boss" game with your friends, or try to count how many times the same potentially frustrating event happens in a day.("I was cut off in traffic 7 times today — I’m almost up to 10!") This works well for predictable or repetitive annoying situations that you can’t control; you can begin to value them in their own special way instead of letting them upset you.
One of the factors that drive the popularity of shows like Modern Family or movies like the classic Ferris Bueller’s Day Off, is that they take somewhat universal situations that many people find frustrating and push them a little further, pointing out the silliness of it all.
What’s more, you can try joining Funny Clubs. Years ago, when Oprah had a show rather than a network, she did a part on Laughter Yoga that interested me, and I researched a club on my own, finding it to be a terrific place to enjoy a good laugh. Whether you mean business or laugh at the silliness of it all, taking part in the exercises of laughter yoga with other humor-participants can be a very effective way to get back in the practice of getting some more laughter into your day.

【推荐1】While mangoes are known as the "King of Fruits", grapes are popularly called as the "Queen of Fruits". The small juicy grapes are sorted into three varieties based on colors: green, red, black or blue. So are there any health benefits in grapes?
Grapes can be consumed in many ways. It can be either eaten raw, consumed in a juice form or used to prepare wine. During autumn, you will find different kinds of grapes in the market. As it is the main season of grapes, the amount of consuming this fruit is very high.
Although grapes are tiny in size, it has numerous health benefits. A lot of people are unaware of the health benefits of grapes. For example, drinking grape juice is one of the easiest ways to treat acidity. Moreover, the fruit juice is also a healthy drink for those who are on a diet.
Grape juice is loaded with nutrients, vitamins and mineral which keep us fit. For example, drinking grape juice is one of the traditional ways to cure a painful headache.
It would be interesting to know that grape juice is good for skin as well. Drinking a glass of grape juice every day helps get a clear and perfect skin naturally.

【推荐2】People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate (下级的) fish voluntarily diet to avoid challenging their larger competitors. "In studying gobies(鰕虎鱼) we noticed that only the largest two individuals, a male and female, had breeding (繁殖) rights within the group," explains Marian Wong. "All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation. "
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical(等级的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive(专有的) to humans. "As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature," the researchers comment. "Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter, than the females' own ideal."
1. When a goby grows to within 5-10% of the size of its larger competitor, it _________.A.faces danger | B.has breeding rights |
C.eats its competitor | D.leaves the group itself |
A.the fish beaten up | B.the fish found out |
C.the fish fattened up | D.the fish driven away |
A.fought over a feast | B.went on diet willingly |
C.preferred some extra food | D.challenged the boss fish |
【推荐3】The moon is providing a rare triple treat this week. On Wednesday, much of the world will get to see not only a blue moon and a “supermoon”, but also a total lunar eclipse(月食). Having all three events taking place at the same time is extremely unusual.
A total lunar eclipse happens when the Earth comes between the Sun and a full moon. The Earth blocks the sun’s light, making the moon appear dark in the sky. A blue moon is a second full moon in one month. It is rare enough that English speakers use the expression “once in a blue moon”to describe it! A supermoon is a full or new moon. It appears brighter and bigger than usual because the moon is closer to the earth than usual.
In a total lunar eclipse, the Earth covers the moon’s surface with its shadow, giving it a red-like color. For that reason, it is also known as a “blood moon. ”Some people are calling this week’s lunar event a “super blue blood moon.” Noah Petro is a scientist with the American space agency NASA. He is calling the lunar event, “the Super Bowl of moons.” No matter what the name, it is likely to impress if the skies are clear.
Just as last August’s total solar eclipse cooled the Earth’s surface, a lunar eclipse cools the surface of the moon. It’s this sudden cooling- from the heat of direct sunlight to almost a deep freeze—that researchers will be studying.
1. Which of the following picture shows a total lunar eclipse?A.![]() | B.![]() |
C.![]() | D.![]() |
A.Something that is rarely noticed. |
B.Something that is round and bright. |
C.Something that does not happen often. |
D.Something that can arouse people’s curiosity. |
A.Make it absorb less heat. |
B.Make it give off less heat. |
C.Make its inner part cooler. |
D.Make its surface heat go down. |
A.It explains how the lunar eclipse happens. |
B.It tells us NASA’s achievements in observing the moon. |
C.It offers us some information about a rare total lunar eclipse. |
D.It is about the effects that the lunar eclipse will have on the moon. |
