Dear Mr. Smith,

    I am seeking an opportunity to work with World Destiny as a Computer Systems Manage. My professional experience and my awareness of your high reputation and great achievements have led me to want to work for World Destiny.

    Since 1998 I have focused on computer-system design and training. As Systems Administrator for Newport Museum for the past two years, I have directed accounting, capital campaign and publication production. We designed the system from scratch, developing all applications, policies, procedures, and training programs. I was well prepared for such a challenge by my previous positions as a Systems Support Specialist and MicroComputer Assistant for the Imperial Corporation of America.

    Over the years, I have worked with Novell, using programs including dBase, Wordstarand Microsoft Word. This familiarity with a variety of hardware and software has helped me to get up to speed on nearly any computer with a minimum training period.

    Additional experience in other fields also adds my value to World Destiny. As a Market Research Coordinator for Cushman & Wakefield of California, I not only researched and maintained（维护）a comprehensive database of Silicon Valley, but also produced statistical and written reports that support Cushman & Wakefield' reputation. Previously, I organized companywide annual sales meetings for Qualogy, Inc.

    Mr. Smith, while this experience more than qualifies me to join any number of successful companies, it is my personal goals that lead to my interest in being part of the World Destiny team. I believe my computer, promotional, and organizational skills, fueled by my beliefs, make World Destiny and me right for each other. Can we arrange an interview at your earliest convenience? I will call within the next week to arrange a meeting.

Sincerely,

Beth Henning

    Nov. 21 is World Hello Day. It began back in the 1970s as part of an effort to make the world more peaceful. It was created by the United Nations just after the war between Israel and Egypt in 1973. The philosophy (理念) behind it is: Say “Hello” and stop war.

    It sounds like a fine idea, but most of us know that simply saying “Hello” won't bring about world peace. Still, on a smaller range, the simple act of saying hello to someone can make a lot of difference.

    This might not be obvious. After all, it's such a casual thing and requires so little effort. You raise your head to someone as you pass by them in the school corridor (走廊), say “Hello' then it's over.

    Although we might not realize it, a small thing like a greeting can mean a lot to a person. Many people are lonely because they're shy. They find it difficult to communicate with people, even though they want lo. It leads to them feeling cut off.

    On this basis, maybe it's a good idea, not just on Nov. 21, but every day, to remember to say “Hello” to as many people as we can. The stranger who hears your greeting may secretly smile in their heart. You might even make their day.

    Greeting other people is the easiest way to be polite. Politeness is the way we individual humans link up with the rest of the human world outside of our circles of family and friends. Politeness is one of the aspects of culture that make us a society rather than just many individuals living in the same space.

    No one said it better than the French author Joseph Joubert: “Politeness is the flower of humanity''. A “Hello” to a stranger is a small thing, and often neglected (忽视), but through it we can make the world better for another person.

    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association ( APEX) spoke to around 1500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia or Brazil.

The results found Chinese travelers are most likely to nod off once the sea-belt sign switches off. They are also the first to reach for their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively —when not drinking —choosing to work while flying a 350000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers — spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via e-mail, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers claiming to read them.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements,” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey,” he added.

    Breathing dirty air comes at a high price. Air pollution lowers the average life spans (寿命) by a year worldwide and in more polluted parts of Asia and Africa, dirty air shortens lives up to twice that much. Scientists shared their new findings in Environmental Science & Technology Letters. The study used data gathered in 2016 as part of a project known as the Global Burden of Disease and was the first major country-by-country look at the connection between the length of life and what's known as fine PM.

    Air pollution has been linked to many health problems. Most earlier studies had looked at how tiny air pollutants affected rates of illness or death. Joshua Apte is an environmental scientist at the University of Texas at Austin. By looking at life expectancy (预期寿命), his team had hoped to make the threat easier to understand. PM2.5 is what scientists call tiny particles (颗粒) of pollution in the air. Higher levels of PM2.5 can cause health problems and cut months, if not years, from the average length of life. This analysis shows how pollution affects life expectancy in different parts of the world.

    The World Health Organization (WHO) recommends limiting PM2.5 to 10 micrograms per cubic meter of air. Apte's group calculated how holding pollution to this low level would help people. In countries with very dirty air, meeting this standard would lengthen people's lives. However, in countries whose air already meets this standard, the study shows no gain in life expectancy. In other words, meeting the WHO standard won't reduce health costs resulting from dirty air because even below 10 micrograms per cubic meter, pollution still causes serious risks. Meanwhile, the scientists compared how other threats including smoking and cancer shorten the length of life across the globe.

    Women may have good reason to drink coffee as much as they like. According to recent research, women who drank three or more cups of coffee a day were 30 percent less likely to have memory decline at age 65 than whose who drank one cup or less daily. And the benefit increased with age. Women over age 80 who drank three or more cups of coffee a day were about 70 percent less likely to have memory decline than those who drank one cup or less, the researchers said.

    Caffeinated tea had the same effect in the women, the study found, although more was needed to get the same caffeine boost. "Count roughly two cups of tea for a cup of coffee," said study leader Karen Ritchie of INSERM, the French National Institute for Health and Medical Research.

    But the researchers didn't find a similarly protective effect in men, although other studies have found a benefit to males.

    How might caffeine help ward off cognitive decline? "It is a cognitive stimulant." said Ritchie. "It also helps to reduce levels of the protein called beta amyloid in the brain" she said, "whose accumulation is responsible for Alzheimer's disease but which also occurs in normal aging."

    Ritchie said she wasn't sure why men in the study didn't benefit from caffeine. "Our hypothesis is that either women metabolize caffeine differently than men, or there may be an interaction of the caffeine with the sex hormones," she said.

    The French study confirms previous research, said William Scott, professor of medicine at the University of Miami Miller School of Medicine, who has researched caffeine's beneficial effects against Parkinson's disease, also a neurodegenerative disorder.

    As for caffeine only protecting women, Scott noted that just 2,800 of the 7,000 study participants were men, and the results might have differed if more men were included.

    A study published in February in the European Journal of Clinical Nutrition looked at 676 healthy men and found that regular coffee drinkers had a lower rate of cognitive decline over a 10-year follow-up than those who didn't drink coffee. Those who drank three cups daily had the least signs of decline.

    Both Scott and Ritchie agreed that more study is needed. Ritchie's research will next look at the relationship between caffeine and Alzheimer's.

    A first-year undergraduate student in Chengdu, recently complained online that her mother refused to raise her monthly allowance to 4,500 yuan ( $ 633) even when she said her current allowance 2, 000 yuan was not enough to cover her expenses, sparking a debate on how much money a college student needs per month. One expert shares his views on the issue with China Daily: Students should pursue education, not comfort.

    Even for a college student studying in a first-tier city in China, 2,000 yuan is enough to cover all his or her monthly expenses. In fact, for a college student in Chengdu a monthly allowance of 2,000 yuan is more than enough. According to a survey conducted by a bookkeeping platform, the average monthly expense for an undergraduate in cities other than Beijing, Shanghai and Hangzhou was less than 2,000 yuan in 2019； for Chengdu, it was 1,900 yuan.

    Claiming that she can hardly afford new clothing and cosmetics with her 2,000 yuan monthly allowance, the undergraduate student in Chengdu criticized her mother for refusing to raise her pocket money. Her "meager" allowance, she said, prevented her from buying branded goods that her hostel-mates enjoyed.

    By the time a person enters a college, she or he should have developed a healthy consumption habit. And a youth should adjust her or his consumption according to her or his family income. On a deeper level, the money they spend in college should depend on how much they value their parents' hard work. Besides, some college students could take UP part-time jobs to meet their monetary needs if they feel their parents don't or can't send them enough money. In this way they can also learn to meet the requirements of life in the future and develop healthy consumption habits. More importantly, they should always bear in mind that education is their top priority in college
