The weather is getting hotter and you'll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

    There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

    But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

    Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

    Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

    Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.

    There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

    Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

    At any discussion of a job offer, money can be a deal breaker. Negotiating an attractive deal, however, can be hard for many job candidates because they lack the necessary skills or simply because they're too concerned that pushing for a high salary can cost them the job.

    These factors certainly can be hurdles (障碍), but it doesn't mean that you give up trying to get the best deal you can get. Needless to say, if money isn't a big factor in your decision, you still need to make sure that the deal you're accepting is fair compared to what's offered in the market. Selling yourself short once can impact your future salaries and set you back financially.

    Here are common mistakes that many jobseekers commit in negotiating money.

    Negotiate too early. Timing is of essence in any negotiation, and negotiating a salary too early in the process can cost you dearly. Many employers, in fact, rank this as one of the biggest mistakes job candidates make. The best timing to begin a salary discussion is after you and your future employer are nearly sure that you've been selected for the position.

    Abandon professionalism. It's common that people, after going through a long recruitment process, can be shocked that the salary offered is significantly below their expectations. If you find yourself in this situation, don't abandon your professional attitude or throw a fit. This likely will get you nowhere except the door.

    There're two options to this situation: the first is that the employer is inflexible (不灵活的) about the budget, and in this case, you may just leave and make a graceful exit from the hiring process.

    The second option is that there's some negotiation room for the hiring manager with other decision makers in the organization. If this is the case, you may be surprised that a final push with a positive attitude and a well-delivered presentation about your skills and market price can get you closer to your expected salary. Still, if this is not acceptable, you don't have to take it.

    Al was a skilled artist. One night, his older son developed a serious stomachache. Neither Al nor his wife took the condition seriously. But it was actually acute appendicitis (急性阑尾炎), and the boy died suddenly that night.

    Knowing the death could have been prevented if he had realized the seriousness of the situation, Al's emotional health became worse. Worse still, his wife left him a short time later, leaving him alone with his six-year-old younger son. The hurt and pain of the two situations were more than Al could handle, and he turned to alcohol (酒) to avoid the pain. Gradually Al became an alcoholic (酒鬼) and began to lose everything he had. Finally, Al died alone in a San Francisco motel room.

    When I heard of Al's death, I felt sorry for him. “What a complete failure!” I thought. “What a totally wasted life!”

    As time went by, I began to rethink my earlier judgment. I knew Al's son, Ernie, one of the kindest and most caring men I have ever known. I watched Ernie with his children and saw the free flow of love between them. I knew that kindness and caring had long come from somewhere.

    One day I worked up my courage to ask him. “I'm really puzzled by something,” I said. “I know your father was basically the only one to raise you. What did he do so that you became such a special person?”

    Ernie sat quietly and thought for a few moments. Then he said, “From my earliest memories as a child until I left home at 18, Al came into my room every night, gave me a kiss and said, 'I love you, son.'”

    What a fool I had been to judge Al as a failure. He had not left any material possessions (财产) behind. But he had been a kind loving father, and he left behind one of the finest, most giving men I have ever known.

    Mr. Lang worked in a factory. As a driver, he was busy but he was paid much. His wife was an able woman and did all the housework. When he came back, she took good care of him and he never did anything at home. So he had enough time when he had a holiday. A few friends of his liked gambling(赌博) and he learned it soon. So he was interested in it and hardly forgot anything except gambling. He lost all his money and later he began to sell the television, watches and so on. His wife told him not to do it but he didn't listen to her. She had to tell the police. He and his friends were punished for it. And he was hardly sent away. After he came out of lockup(拘留所), he hated her very much and the woman had to leave him.

    It was New Year's Day. Mr. Lang didn't go to work. He felt lonely and wanted to gamble again. He called his friends and they came soon. But they were afraid that the police would come. He told his five-year-old son to go to find out if there were the policemen outside. They waited for a long time and didn't think the police would come and began to gamble. Suddenly a few policemen opened the door and came in.

    "I saw there weren't any policemen outside, daddy," said the boy, "so I went to the crossing and asked some to come."

    Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.

     There are several major(主要) language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.

    Regardless of how far we'd like to believe gender (性别) equality in the workplace has come, there's still a yawning gap between male and female leaders in the professional world. A 2018 statistic showed that women nowadays hold just 5.8 percent of CEOS positions at S&P 500 companies, according to Catalyst.

    While it's not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School.

    In their research, Professor Oyvind L. Martinsen and Professor Lars Glas surveyed 2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in four of the five major leadership-centric categories while some people believe that men inherently make better leaders—probably because they picture a leader with a commanding voice, which is more typical of men than women—this is piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.

    There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress. The results suggested that women are more sensitive to the effects of high-pressure or highly emotional situations.

    Obviously, it's important to consider individual (个人的) differences. Anyone, regardless of gender, may be an inspiring leader and a competent boss. But next time you're hiring for a management position, you just might want to give the resumes(简历) from female candidates a harder look.
