To err is human. To blame the other guy is even more human.

    Common sense is not all that common.

    Why tell the truth when you can come up with a good excuse?

    These three popular sentences are meant to be jokes, and yet they tell us a lot about human nature .To err, or to make mistakes, is indeed a part of being human, but it seems that most people don't want to accept the responsibility for the problem. Perhaps it is the natural thing to do .The original quote about human nature went like this: " To err is human, to forgive, divine(神圣的).".This saying mirrors an ideal people should be forgiving of others' mistakes. Instead, we tend to do the opposite –find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a making of great maturity.

    Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company, "the right hand does not know what the left hand is doing."

    And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it's okay not to be totally honest all the time. There is a corollary(直接推论)to that: if good excuse is "good" even if it isn't honest, then where is the place of the truth?

    Since the sex of a sea turtle(海龟)is determined by the heat of sand hatching the eggs, scientists had suspected they might see slightly more females. Climate change, after all, has driven sea temperatures higher, which, in these creatures, favors female children. They found female sea turtles from Raine Island, the Pacific Ocean's largest and most important green sea turtle living area, now outnumber males by at least 116 to 1. "This is extreme," says turtle scientist Camryn Allen.

    Biologist Michael Jensen wanted to know if climate change had already changed turtles' sexes. By using genetic(基因的) tests, he'd figured out that he could follow turtles of all ages. Still, his research data would lack an important detail: sex. Only after a turtle matures is it possible to tell its sex from the outside -- mature males have slightly longer tails. By then turtles can be decades old, so scientists often use Iaparoscopy(腹腔镜检查)，sending a thin tube into each animal, but that's not so practical if you're hoping to examine hundreds of creatures. Fortunately, at a turtle conference, he met Allen, and all she needed was a little blood.

    They compared their results with temperature data for nesting beaches. What worries them is that Raine Island has been producing almost female turtles for at least 20 years. This is no small thing. More than 200,000 turtles come to nest there. During high season, 18,000 turtles may settle in at once. "But what happens in 20 years when there are no more males coming up as adults? Are there enough to maintain the population?" says Allen. They also found cooler beaches in the south are still producing males, but that in the north, it's almost entirely females hatching. These findings clearly point to the fact that climate change is changing many aspects of wildlife biology.

    But how widespread is this phenomenon -- and what is the consequence?

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.

So, it is important to give the brain a rest. And being in naure, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example .He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a “regenerative” experience.

    At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found, it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, people, events and the resulting effects.

    People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well-prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, hurt many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy people would be more pitiful. The intention of criticising and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realise its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people hurt many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in a bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favour their hopes. If they bring public objections to themselves, no one will defend or excuse them, and many will join in to criticise their wrongdoings. They should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

Traditional Chinese festivals always have {#blank#}1{#/blank#} (they)symbolic foods. The Dragon Boat Festival-or Duanwu Festival-features zongzi, or sticky rice dumplings. For the Dragon Boat Festival, which {#blank#}2{#/blank#} (fall)on the fifth day of the fifth month of the lunar calendar, the core ideas are getting rid of diseases, avoiding disasters and {#blank#}3{#/blank#} (wish)for good health. 

Wen Yiduo, {#blank#}4{#/blank#} poet and academic, wrote that on the fifth day of the fifth month, people threw rice dumplings into the water and raced the dragon boats activities to express their fear of the dragon below and the hope that it will not make trouble in the {#blank#}5{#/blank#} (day)to come. 

The most {#blank#}6{#/blank#} (wide)known story of Duanwu Festival is that it was started {#blank#}7{#/blank#} (remember) Qu Yuan, {#blank#}8{#/blank#} committed suicide on the fifth day of the fifth lunar month. People threw sticky rice dumplings into the river {#blank#}9{#/blank#} the dragon underwater would not eat his body. 

Eating rice dumplings {#blank#}10{#/blank#} (be)one shared custom. There are also traditions unique to other ethnicities. For Dai people in Yunnan, for example, Duanwu Festival is an annual opportunity to express admiration to others.
