【推荐1】Researchers have found multilingualism (多语言能力) is good for economy. Countries which actively encourage the development of different languages gain a range of rewards, from more successful exports to a more creative workforce.

“Language matters on a larger national level and at the level of smaller companies,” said Hogan-Brun, a researcher in language study. Switzerland, for example, owes 10% of its GDP to its multilingual background. The country has four national languages. Britain, on the other hand, is thought to lose about 3.5% of its GDP every year since 95% of its population speaks English, which is the primary language of the country.

What Hogan-Brun said is reasonable. Languages partly can help build trade relations. A study of small and medium-sized companies in Sweden and Germany found that those that invested more in languages were able to export more goods. German companies that invested heavily in multilingual staff added 10 export countries to their markets. Companies that invested less said they missed out on business deals.

Researchers have also long stressed the individual benefits of speaking more than one language. Several studies show that languages help promote earning power. According to a Canadian study, women and men who can speak several languages earn 3.6% and 6.6% more than their English-only colleagues respectively. The twist: This is true even if they don’t use their second language for work. “It seems that you don’t have to actually speak a second language on the job to receive the financial rewards,” said an economics professor. He thought that this was because knowing a second language was seen as a sign of power. Beyond these immediate economic rewards, languages can help a country’s workforce in long-term ways. Multilingualism has been shown to delay memory loss. It has also been associated with a better ability to concentrate and process information.

From the sixteenth century on, the word “farm” has meant agricultural land. But a much older meaning of the word “farm” is linked to economics. The word “farm” comes from the Latin word “firma”, which means an unchanging payment. Experts say the earliest meaning of the English word “farm” was a yearly payment made as a tax or rent.

Farmers in early England did not own their land. They paid every year to use agricultural lands. In England, farmers used hawthorn trees along the edges of houses. They called this row of hawthorns a hedge. Hedging fields was how careful farmers marked and protected them. Soon, people began to use the word “hedging” to describe steps that could be taken to protect against financial loss. Hedging is common among gamblers who make large bets. A gambler bets a lot of money on one team. But, to be on the safe side, he also places a smaller bet on the other team, to reduce a possible loss.

You might say that someone is hedging his bet when he invests in several different kinds of business. One business may fail, but likely not all. Farmers know that it is necessary to make hay while the sun shines. Hay has to be cut and gathered when it is dry. So a wise farmer never postpones gathering his hay when the sun is shining. Rain may soon appear. A wise person copies the farmer. He works when conditions are right.

【推荐1】A Good Night’s Sleep

Sleep plays a vital role in good health and well-being throughout your life. While you’re sleeping, your brain is forming new pathways to help you learn and remember information. Although we all know the importance of getting a good night’s sleep, not all of us know the best way of getting it. A sleep expert, Phil Atherton, gave some top tips for getting the most out of the night, which will leave you ready for action in the morning.

According to Phil Atherton, not eating a large meal before bedtime is important for getting a good night’s sleep. The time difference between eating and sleeping should be at least three hours. So you’d better avoid eating any food three hours before bed, as it will lower your blood sugar during sleep and help minimize damage from too much sugar floating around.

It’s also important to find ways to prepare your body for sleep. You can follow a routine like trying not to expose yourself to too much artificial light within 1 hour before bed, as your brain uses light to help set internal “body clock”. Although it might seem unnatural to schedule your sleep, the purpose is to send a signal to your body and mind that it’s time to sleep.

Another way to prepare your body for sleep is to get into a relaxed state by taking a bath or listening to soft music. Both of them will help to take the mind off the daytime pressures.

Having a suitable bed, especially a suitable mattress (床垫), is necessary for a good night’s sleep. Sleep is a personalized activity, and we all adopt different sleeping positions. Finding the mattress that suits you will reduce back pains that can result from a poor sleeping position. The bed should be four to six inches longer than its tallest user, allowing for space to move around.

The recent research is pretty clear that a good night’s sleep is a major component of good health. Since the start of the 21st century, studies have linked a lack of sleep to many diseases, such as diabetes and obesity. Taking action now will lead to long-term benefits for you and those around you.

It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device which uses satellites to find the user’s position. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put it in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car,plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

The GPS is becoming cheaper and more and more accurate. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
