A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower.

    A biodegradable (生物所能分解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.

    Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and is able to change shape. Over time it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms fertilizers. These feed the seed and help the flower grow.

    Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is throw n away. “We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.

    As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be throw n away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists.

    “The seed comes out and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.

    The English language is full of phrases about the weather. Some of these phrases are easy to understand, but others are not really about the weather at all. If you say you "hit rough weather", you may not be struck by a real storm, but you do experience difficulties or problems. If you don't know what such phrases mean, they might leave you "in a fog (雾)"!

    In English, you can "shoot the breeze", or have an informal chat. But things can also be a breeze. If you take an exam and find it very easy, you'd tell your friends: "It was a breeze!" The wind can also bring information. You can "get wind of" a piece of news, and if someone "knows which way the wind blows", they have a good idea about how things will work out. But don't "throw caution (警惕) to the wind" — that means taking a great risk!

    Clouds sometimes bring rain, and in English they often represent problems or difficulties. If someone "sees a cloud on the horizon (地平线)", there may be problems ahead. And if someone is "under a cloud", then people think the person might have done something wrong. But clouds are not always bad; in fact, people say that "every cloud has a silver lining". This means that there is a good side to every situation, no matter how bad it may seem. You may even end up "on cloud nine", which means you are very happy! But some people have their "heads in the clouds", not paying attention to reality.

    No one likes to be stuck in the rain or storm, so it's no surprise that phrases about them are generally negative. When someone says "it never rains but it pours", they are complaining (抱怨) that when things go wrong, they go very wrong. People who talk about "weathering a storm" just want to get through a difficult period or situation.

    Five-year-old Prisilla Perez, a student at Meador Elementary School in Willis, was unhappy with her recent haircut, which resulted from a severe disease. When students in her class started calling Prisilla a boy, she felt ashamed, often crying and losing focus in school.

    Her teacher, Shannon Grimm, sympathized with her unhappiness. Grimm and Prisilla's mom were concerned, but their ideas didn't work. “We had classroom discussions about how girls have short hair and boys have long hair, and I showed them photos of movie stars with different looks,” Grimm said. “However, it wasn't sinking in.”

Grimm thought about Prisilla throughout winter break, and one morning, she had an idea: Cut off her hair — a scary thought for Grimm, who wore her hair long and took pride in it. “I've never had short hair, and I stressed about it for two weeks before making a decision,” she said. On Jan. 4, Grimm invited a hairstylist friend to her home. “I told him to keep going, even if I cried,” she said.

    The class loved their teacher's new do, especially Prisilla, who excitedly ran off the school bus that afternoon yelling, “Mom, Ms. Grimm cut her hair!” The teacher also bought matching bows for herself and the girl, so they could style their hair together.

    In February, the teacher recommended Prisilla for the school district's Student of the Month Award, but during the Monday ceremony, she received a surprise “hero medal” from the girl. “Now we have matching awards,” says Grimm.

Prisilla's mother, Maria, said that Grimm's thoughtfulness brought her to tears. “I was shocked. I was crying. I couldn't believe it — she did something I wouldn't have the bravery to do. I will never forget that.”

    Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.

    A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.

    According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.

    The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans.

    "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."

    Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.

    We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.

    Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.

    Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day's work with the difficult task of essay-writing. Experience proved that the rule works.

    Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.

    When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after dat I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.

    One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.

    An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.

    Human beings, I believe must try to succeed. Success, then, means never feeling tired.

    While IQ (Intelligence Quotient) tells you how smart you are. EQ (Emotional Quotient) tells you how well you use your smartness. Professor Salovery, the psychologist who created the term, EQ, says that it is IQ that gets you hired but it is EQ that gets you promoted.

    Supported by his research, he suggested that when predicting future successes, a person's brainpower, as measured by IQ tests, might actually matter less than a person's character, or EQ. Professor Salovery may be correct. For example, have you ever wondered why some of the best and smartest students in your class end up failing exams? Perhaps it is because of their EQ. People often make the mistake of thinking that EQ is the opposite of IQ. It is not. Although it is hoped that people have both high EQs and IQs, there is little doubt that those with low EQs have a hard time surviving in life.

    For a long time, researchers discussed if a person's IQ could be raised. The geneticists said no, while the social scientists said yes. Furthermore, the social scientists said that it was possible to improve a person's EQ, particularly in terms of "people skills", such as understanding and communication.

    Recently, a professor released the findings of a study on senior high school students. When some normal students were introduced to some disabled students, they found that afterwards they were more willing to help people in difficulties. At the same time, there was a marked change in the disabled students' attitudes. They became more positive about their disabilities and were more eager to try new things. People with high EQs often have positive attitudes towards life and are open to different ideas, so they tend to be more creative in their thinking. Please remember that having a high IQ is helpful but having a high EQ might even be more helpful.
