As the weather turns colder in some parts of the world, signs of autumn begin to appear. At this time of the year depending on your location, you may also see a familiar flower: chrysanthemums ( 菊花). We often call them “mums,” for short.
In parts of the United States, many people use chrysanthemums as decorations. The flowers sit next to pumpkins for Halloween, October’s famous holiday. But then the mums are thrown away along with rotting jack o’lanterns.
This yearly tradition bothered plant expert Jessica Damiano. In a recent article, she wanted to know why people simply threw away their mums. So, she asked some of her neighbors in Long Island, New York.
Everyone had the same answer: They thought the flowers were annuals — flowers that only last for one season.
Damiano explained that there are annual and perennial (多年生的) mums. Perennials come back for several growing seasons. Garden chrysanthemums, she adds, are actually perennials. Annual chrysanthemums are often sold in stores as potted gift plants. Special plant stores usually sell perennial mums.
If the plants are not labeled at a store, Damiano said to look at the leaves. The large, flat leaves of perennial mums have deep cuts around the edges. The narrow leaves of annuals do not.
Perennial mums are hardy flowers. But they cannot survive freezing temperatures. They also cannot survive extreme summer heat. So, that means about half of the United States is good for growing mums.
Perennial chrysanthemums come from China. Kaifeng, a city in China’s Henan province, is famous for its mums. Each year, the city holds a popular festival to celebrate the flowers. Chrysanthemum festivals are also held in other countries — like Pakistan, Germany, South Korea, Japan, and the United States, to name a few.
Chrysanthemums come in shades of orange, red, rust, pink, purple, yellow, cream, and white. Some can grow to nearly one meter in height. They reach their mature size in about three years. In warmer climates, they bloom again in spring.

【推荐1】Very few animals except dolphins, chimpanzees (黑猩猩),and elephants have ever passed the mirror test for self-recognition. Scientists believe they have found a fish able recognize itself in a mirror. The result is surprising because this ability is usually only found in animals with bigger brains. Even humans don't usually pass the mirror test until they are about a year and a half old.
To test the wrasse (隆头鱼), a small fish in the sea, scientists put each wrasse in a tank with a mirror. They gave the fish a chance to get used to the mirror and watched their reactions. At first, the wrasses challenged the "other fish" by swimming up to the mirror and "fighting" them with the mouth. But soon the wrasses seemed to understand that something funny was happening. They began to swim toward the mirror upside down or in other unusual ways. It was like they were testing whether the fish in the mirror were really themselves.
Once the wrasses seemed used to the mirror, the scientists gave the wrasses a mark by putting the fish to sleep and injecting something under their skin. Some of the fish got a brown mark. Other fish got a clear "mark" that didn't have a color and couldn't be seen in a mirror.
After looking in the mirror, the wrasses with the brown marks would rub the area with the mark against the sand in the bottom of the tank. Then they would go back and look in the mirror again, as if checking if the mark was still there. But when wrasses with brown marks were put in tanks without mirrors, they didn't try to rub their marks away. And wrasses with clear "marks" didn't either, even when they could see themselves in the mirror.
The unexpected results are making some people look hard for other ways to explain how the wrasses reacted. So even though the wrasses seem to have passed the mirror test, the scientists will need some time to reflect on exactly what that means.

Researchers found that women are overcome by a burning desire to share gossip (流言蜚语) as soon as they hear it. They will typically tell the secret to at least one other person in 47 hours. Depending on who the gossip is about, their boyfriend, husband, best friend or mother is most likely to be the recipients of the information.
The study of 3000 women aged between 18 and 65 also found that out of ten admitted they were unable to keep a secret—no matter how personal or secret the news was. It was also found that alcohol usually gives us a helping hand to let out secrets—with more than half admitting a glass or two of wine could get them to dish the dirt.
Michael Cox, UK Director of Wines of Chile, said, “It’s official women who can’t keep secrets. We are really eager to find out with this survey how many secrets people are told. What we don’t count on is how quickly these are passed on by those we trust. No matter how precious the piece of information is, it often comes out within 48 hours.”
Three quarters say they are able to keep quiet about a secret, and 83 percent consider themselves 100 percent reliable within each group of friends. Yet, four in ten admit gossiping to a close friend from another friendship group. Nearly half (45 percent) disclose secrets just for the weight to be lifted from their shoulders. More than four in ten think it is acceptable to share a friend’s secret with someone who doesn’t know him or her.
Private issues, true cost of purchases and affairs emerged top of the secret-keeping list, with girls most likely to share a secret chatting face-to-face, on the phone or via a text message. Fortunately, over a quarter (27 percent) said they forgot what they were told the following day.

【推荐1】People say money doesn’t buy happiness, but how much money you make can affect the way you experience it?
While it’s true that money can’t buy happiness, having money has certain benefits. For example, money can buy you time to do things that make you happier, and giving away some of your money can make you happier as well. Now scientists from the University of California at Irvine have found that how much money you make may impact (影响) how you experience happiness; higher earners are more likely to experience positive emotions focused on themselves, while lower earners are more likely to experience positive emotions focused on connecting with other people.
Scientists used data from an existing survey of 1,519 U.S. adults between the ages of 24 to 93, to be representative of the entire U.S. population. From the survey, scientist collected the household income of each person and analyzed how each person experienced the seven emotions that are believed to cause happiness: amusement, admiration, compassion, satisfaction, enthusiasm, love, and pride.
What they found was that higher earners were associated with the happiness-related emotions of satisfaction, pride, and amusement, all of which are self-focused in nature. Lower earners were associated with more other-oriented (他人指向) happiness-related emotions: compassion, love, and admiration. There were no differences observed with enthusiasm.
As to reasons for the difference, the researchers suppose that while pride and satisfaction may reflect upper class individuals’ desire for independence, increased love and compassion may help lower class individuals form more harmonious (和谐的), interdependent bonds to help deal with their more threatening environments. In other words, the researchers are not saying that one way of getting happiness is better than another, but rather that the way one obtains happiness may be a product of existing and coping within one’s particular circumstances.

【推荐2】During the cool months from October to March, camel caravans (骆驼车队)arrive in the desert city of Timbuktu (廷巴克图)every few days. Led by Tuareg and Arab traders, the caravans have traveled from the salt mines of Taoudenni in Mali.
Nowadays, each salt caravan has from 60 to 300 Camels. Each Camel carries four to six bars of salt. The journey from the mines to Timbuktu takes 15 days.
At Taoudenni, salt is mined from ancient lake-beds that dried up millions of years ago. The mines lie deep below the Earth’s surface and are reached by tunnels. Large blocks of salt are dug out and then cut into small blocks above ground.
Trucks are taking the place of camels carrying salt. One truck can carry hundreds of bars of salt. And a truck can make the 900-mile round trip in about a week.
A.Mining salt is a very hard job. |
B.Traders are familiar with the mines there. |
C.Something bad happens to the camels on the way. |
D.The days of the camel caravans are coming to an end. |

【推荐3】Chinese is one of the world’s most widely spoken language. As one of the six official languages used by United Nations, Chinese now has gained itself greater status (地位) in the world. Chinese is interesting and special. Unlike most other languages, Chinese has a written form and several spoken forms. The official language of China is the Mandarin (普通话).
Mandarin is a statement in China. It is the common language of all modern Han nationality people. Mandarin is shaped and based on the Beijing dialect (方言) and other dialects spoken in the northern areas of China. Mandarin is taught in schools throughout the country. The media, officials, and the government use Mandarin as their main language. When you type in Chinese, you use a phonetic system, called pinyin, which matches the Mandarin pronunciation. Mandarin is used as a mother tongue by most people who are about one fifth of the world’s population. Chinese once had very great influence on some neighboring countries with their languages and characters, such as Japanese, Korean, Vietnamese and so on. In addition to China, Mandarin is an official language in several other countries in Asia.
Nowadays, with the development of China, Chinese people not only speak Chinese, but also learn other languages, such as English. English is a required course and universal education in China and has great popularity. Many Chinese people can speak basic English, especially the youth, students, and staff of service trades like hotels, restaurants, airlines, banks and post offices. In large cities, there are more people who can communicate with foreigners in English. The language communication now is not a problem at all for those that wish to come to China.
Now Chinese is becoming more and more popular. As long as you know Chinese, you’ll also be fine anywhere in China.

【推荐1】Bamboo is the tallest member in the grass family. It is one of the fastest growing plants on earth, growing reportedly up to 98 inches in just 24 hours. Bamboo is mainly found in Asia, some parts of Africa and parts of the America in many different varieties. Over centuries bamboo has had a variety of uses like medicine, paper, construction, furniture, home decoration and musical instruments.
The use of bamboo as a construction material is not new and many countries have been using it to build homes for centuries. Bamboo’s unique and efficient natural design makes it a good building material.
Bamboo is very flexible and hence when it grows it can be defined to grow into specific shapes. Its shock absorption capacity (减震功能) makes it a great building material for earthquake- resistant houses. Bamboo houses can also stand a hurricane with wind speeds of up to 170 mph.
Bamboo is cheap and readily available in areas where it is cultivated. Transportation of bamboo is also cheaper than other materials.
The most important quality of bamboo is its environmentally friendly quality. It is renewable and bamboo forests can be grown in a few years. Its naturally smooth surface does not require painting, making it safe from health dangers caused by paint. Bamboo can be grown in a variety of climates and houses made of bamboo do not require use of other materials like concrete (混凝土), steel, etc. Pesticides (杀虫剂) and other chemicals need not be used while cultivating bamboo, making it more eco-friendly.
Bamboo also has certain drawbacks. For example, not all types of bamboo can be used for construction. Bamboo cannot be used to build the skyscrapers that we all love. Wet bamboo deteriorates (变坏) faster.
Despite all the drawbacks, the environmentally friendly features of bamboo make it a great building material. The few drawbacks that bamboo has can be mitigated with research and the use of bamboo as an alternative building material should be encouraged to make our earth greener.

【推荐2】Weeds, the fast-growing plants that cannot be eaten and do not bring flowers, are a common problem for gardeners. Some use chemicals to kill weeds. Others pull them up by hand or with heavy machinery. Luckily, there are other ways to limit their growth.
For starters, there are mulches which can bury weeds. Mulches are made from organic material, such as leaves, grass cuttings, and small pieces of wood. They are spread over the ground in a garden to control weeds. Organic mulches break down over time.
Plastic mulch is another way to stop weeds. Common black plastic is easy to lay down. It also effectively blocks weeds and helps soil warm faster in the spring.
Finally, in addition to direct attacks on weeds, how you plant your garden can indirectly influence weed growth. For example, close spacing of plants in the garden blocks sunlight from reaching the ground and can limit weed growth. And using a watering method known as drip irrigation will direct small amounts of water to the roots of your plants instead of the weeds.
Using any or all of these methods will not permanently stop weed growth.
A.So you must add more to your garden often. |
B.And plastic also can block air from reaching the soil. |
C.However, we could finally make it through our efforts. |
D.So it adds little to the soil in terms of humus or nutrients. |
E.Instead, your goal is simply to limit their growth in the garden. |
F.Whether or not you dig up your soil also influences weed growth. |
G.Recent experiments with other colored plastic have shown effects on both bugs and plant growth. |
【推荐3】Young trees don’t just grow; they develop a personality and learn more about their environment and how they should best behave in it. They also help each other out whenever there’s trouble.
Personality, just as among people, varies among trees. Some are anxious, some bold. On the author’s land, there are three oak trees growing close together. One of the oak trees always starts to shed its leaves two weeks earlier than the others. Since they all experience the same temperature, the same soil and the same length of day, such variables can’t be the explanation. So what’s happening?Well, this tree is simply more careful than the others. Whoever holds on to their leaves longer can do more photosynthesis(光合作用) and store more nutrients.However, the longer a tree keeps its leaves, the higher the risk of injury.
Not only do trees make their own decisions, they also learn from their mistakes. A tree, for example, keeping its leaves too long during one year will never make this mistake again. This leads to several other conclusions: trees must notice the temperature and the length of the day and be able to save their experiences somewhere. Obviously, trees don’t have brains,but it is thought that in the sensitive tips of their roots they keep track of information and experiences.
But trees aren’t only clever when it comes to caring for themselves. They also support each other whenever there’s trouble by giving warnings and even taking care of sick and weak conspecifics with nutrients. For example, one time the author found a very old tree stump. Its insides had rotted a long time ago to topsoil. But the wood on the outside of the stump was still living. How was this possible?Well, the stump was nourished by its neighbors with nutrients from the root system, and had been for at least 400 years!
Why do trees do such a thing? It’s simple: it’s better together. Trees need the forest; it protects them from storms, provides the right microclimate and warns them of attacks.
