Sorry to say, our brains pastorally start slowing down at the cruelly young age of 30. It used to be thought that this couldn’t be helped，but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,” says University of California scientist Dr. Michael Merzenich. Given the right tools, we can train our brains to act like they did when we were younger. All that’s required is the practice designed just for the purpose: a few exercises for the mind.

Merzenich has developed a computer-based training method to speed up the process (过程) in which the brain deals with information (positscience com ). Since much of the data we receive comes through speech, the Brain Fitness Program works with language mad hearing to better speed and accuracy (准确性).

Over the course of training, the program starts asking you to distinguish (辨别)sounds (between “dog” and “bog”, for example) at an increasingly faster speed. It’s a bit like tennis instructor, says Merzenich, hitting balk at you faster and faster to keep you challenged(受到挑战). You may start out slow, but before long you’re pretty quick.

The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic. If you ask your blain to learn，it will learn. And it may even speed up while in the process.

To keep your brain young and plastic you can do one of a million new activities that challenge and excite you：playing table tennis or bridge，doing crossword puzzles，learning a language....“When it comes to preventing ageing，you really do use it or lose it’s，”says Barbara Sahakian, professor at Cambridge University.

Americans use many expressions with the word dog. People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy life.

Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.

Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.

Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. But mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.

Dog expressions also are used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs.

Romantic love is a culture trait found primarily in industrialized societies. Elsewhere in the world, pragmatic(重实效的) considerations rather than flights of fancy are often used to make a choice of partner, and romantic love is seen as an unfortunate inconvenience that gets in the way of the ordinary, rational process of mate selection. Traces of this attitude persist in the American upper classes, where daughters are expected to marry “well”-----that is, to a male who is eligible by reason of family background and earning potential. Most Americans, however, see romantic love as essential for a successful marriage, and tend to look askance（轻蔑地）at anyone who marries for a more practical reason in which love plays no part.

The phenomenon of romantic love occurs when two young people meet and find one another personally and physically attractive. They become mutually absorbed, start to behave in what appears to be a flighty（充满幻想的）, even irrational manner, decide that they are right for one another, and may then enter a marriage whose success is expected to be guaranteed by their enduring love. Behavior of this kind is portrayed and warmly endorsed（赞同）throughout American popular culture, by books, magazines, comics, records, popular songs, movies, and TV.

Romantic love is a noble ideal, and it can certainly provide a basis for the spouses to “live happily ever after.” But a marriage can equally well be founded on much more practical considerations”----as indeed they have been in most societies throughout most of history. Why is romantic love of such importance in the modern world? The reason seems to be that it has some basic functions in maintaining the institution of the nuclear family（小家庭）.
