    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well.

    Green is also the color used to describe the powerful feeling , jealousy(嫉妒). The green-eyed monster （怪物）is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

    In most places in the world, a green light means to move ahead. In everyday speech, a green light means agree to continue with a project.

    A sense of humor is something highly valued. A person who has a great sense of humor is often considered to be happy and socially confident. However, humor is a double-edged sword. Sometimes it can damage self-respect and annoy others.

    People who use bonding humor tell jokes and generally lighten the mood. They're thought to be good at reducing the tension in uncomfortable situations. They often make fun of their common experiences, and sometimes they may even laugh off their own misfortunes. The basic message they deliver is: We're all alike, we find the same things funny, and we're all in this together.

    Put-down humor, on the other hand, is an aggressive type of humor used to criticize others through teasing. When it's aimed against politicians, as it often is, it's extremely funny and mostly harmless. But in the real world, it may have a harmful effect. An example of such humor is telling friends an embarrassing story about another friend. When challenged about their teasing, the put-down jokers might claim that they are "just kidding," thus allowing themselves to avoid responsibility. This type of humor, though considered by some people to be socially acceptable, may hurt the feelings of the one being teased and thus have a bad effect on personal relationships.

    Finally, in hate-me humor, the joker is the target of the joke for the amusement of others. This type of humor was used by comedians John Belushi and Chris Farley—both of whom suffered for their success in show business. A small amount of such humor is charming, but routinely offering oneself up to be embarrassed destroys one's self-esteem, and fosters depression and anxiety.

    So it seems that being funny isn't necessarily an indicator of good social skills and well-being. In certain cases, it may actually have a negative effect on interpersonal relationships.

    When we do something, we all have our own plans. Some people are born planners. I can't claim (宣称) to be one of that kind of people. Most of the time, I try to at least expect what might go wrong. I have taken to making lists and, although I'm not yet achieving perfection, I usually manage to achieve goals. But there are times when even the best plans do not succeed. All that is left then is to smile and to make or do something using whatever is found.

Hanukkah (光明节) came early this year, perhaps too soon after Thanksgiving to allow us to prepare well. During the first night of Hanukkah, the Hanukkah candles were nowhere to be found in the entire Dallas area where we lived. Birthday candles wouldn't work! The tall long thin candle fell in small drops. "What would our ancestors do?" I thought. "What shall I do now? That's where ingenuity comes from. Don't be nervous and worried. Never let missing candles spoil a family celebration." Later what we did find was a bag of tea lights. The long, silver bread tray became the base for our tea lights. The younger ones were wide-eyed and happy as Grandpa lit the first tea light and all recited the blessing. We sat at the dining table, happy to be together and the food was plentiful.

    No matter how imperfect it is, the fact that families gather to share a special event, an event that has held meaning for so many generations of families, is the meaning itself and forms the important part of the observance (仪式). What we need to remember, and to carry with us, is the knowledge that togetherness is much better than all other concerns.

    “Long time no see” is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish.

    Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too surprised to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

    Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan's movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.

    Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.

    You can have some other examples than adoptions（采用）from Chinese, such as pizza from Italian, susi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.

Rescue workers and thousands of volunteers are not the only ones who have won hearts and minds for their heroic efforts in the search for survivors after Tuesday's powerful earthquake in

Mexico. Fifteen dogs from the navy's canine (军犬) unit have assisted this week in the rescue efforts at the sites of collapsed buildings across Mexico City, where more than 50 people have been pulled alive from the ruins.

Of the canine heroes none is more famous or loved than Frida, a six-year-old white Labrador who in her distinguished service has won praise for her ability to detect people who have been trapped by various natural disasters. Over her admirable career she has found 52 people including 12 survivors in Mexico and other Latin American countries.

This week, Frida and Evil and Echo—two Belgian Shepherds that have also been specially trained for rescue efforts一were sent to the site of the collapsed Enrique Rebsamen School in southern Mexico City.

Equipped with goggles that protect her eyes from dust and smoke, boots to prevent damage to her paws while she climbs over rough ruins, Frida took to her work looking every bit the part of the ruins.

If Frida detects the presence of a survivor, she is trained to bark to alert rescue workers but if she detects a corpse she stops suddenly before proceeding, her handler explained.

Eleven children were rescued from ruins at the school but this time human rescue workers rather than the dogs were the ones who located them.

However, that hasn't stopped Frida from becoming a social media star and reaching a new level of fame this week. Videos and other social media posts that highlight the work of Frida and her impressive record of detecting people trapped by natural disasters spread quickly online.

While she has yet to detect anyone trapped in the ruins this week, she and other rescue dogs are continuing to work tirelessly, searching through spaces that humans cannot reach. With the possibility that there are still people trapped alive, time will tell whether she adds to her rescue record.
