It has been suggested that girls do not take math courses, not because they are difficult, but for social reasons. Girls do not want to be in open competition with boys because they are afraid to appear less feminine (女性的) and attractive (有魅力的).

However, there are still more high-achieving boys than girls when taking math exams. This difference appears to be worldwide. Biological explanations have been offered for this, but there are other explanations too.

Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences. From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who gave answers.

Besides, there can be little doubt that teachers of math and science expect their boy students to do better at these subjects than their girl students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and math and to give them confidence that they are able to succeed.

Such a way of teaching is not likely to encourage girls to take many math and science courses, nor is it likely to support girls who do. When it comes to these subjects it seems certain that school widens the difference between boys and girls.

It is likely that your living room will have a television set and a video,and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.

Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Getting material success is beginning to trouble large numbers of people around the world. They feel that the long-hours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family. Many are turning to other ways of living and downshifting is one of them.

Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs (郊区), leaving their two children with a nanny (保姆). Most evenings Daniel wouldn’t get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by.

Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm here,” says Daniel, “ and we took almost a year to make the decision to downshift. It’s taken some getting used to, but it’s been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it’s made us stronger as a family, and the children are a lot happier.

Liz, However, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I’m not really a country girl, but I suppose I’m gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much or you might not do it at all”

【推荐1】There’s no doubt that positive thinking impacts one’s life. However, in recent years, I’ve come to understand that perhaps positive thinking can result in toxic (有毒的) positivity, which has negative results. What we should be aiming for instead is emotional validation (确认) .

Toxic positivity is the maintenance of positive thinking even in situations where it isn’t appropriate. “It often comes at the risk of denying(否认) our own real feelings or the feelings of others,” says Nina Vasan, MD. While positive thinking in general is a great thing, toxic positivity isn’t. It’s the act of denying anything negative that’s actually happening, and it can involve making people feel bad for having normal human emotions. Someone practicing toxic positivity might say things like “everything happens for a reason” or “just look on the bright side” when a friend shares something difficult in his/her life.

Vasan tells us that with toxic positivity, emotions like sorrow and anger are pushed aside. However, emotional validation allows you to have your feelings. To be exact, emotional validation is about allowing people to experience their feelings and acknowledging that having negative feelings is real and often important. That doesn’t mean it promotes and encourages negative thinking endlessly, though.

Toxic positivity encourages us to focus only on the positive, which can stop us from dealing with the feelings we need to work through. Practicing emotional validation is a healthier option for you and the ones you love. “This can be as simple as saying ‘I understand you’re really sad’.” explains Vasan. Offering your understanding shows our loved ones that we care about their feelings. Besides, instead of telling someone to look on the bright side, you should offer words and thoughts of support instead.

Toxic positivity has become prevalent, and you probably know a lot of people who dismiss your negative experiences with statements like “you’re too sensitive”. Now you can say: Whatever you’re feeling is temporary and allowing yourself to feel it will help you get through it.

【推荐2】It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere—not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths — one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.
