Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and grey hair. But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-Up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s—much later than previously thought.

Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years, it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive(认知的)tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words they can remember) and problem solving. Where they performed less well was number ability and perceptual speed—how fast they can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

Neuroscientists are also finding that we are happier with age. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we are younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life; therefore, it becomes more important for us to be happy.

1. When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, visions of country clubs dance into view.

The many wants of mankind might be regarded as making up several levels. 2. .

The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. 3.It included such items as cars and new houses.

By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction-the feeding, comfort, safety, and transportation of the human body-this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items(奢侈品). Among them are vacation trips, the best medical care, and entertainment. 4.

On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

A fifth level probably would be wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. 5. In this way, we can enjoy more fully the good things on the first four levels.

A.Then a third level appeared.

B.Human wants seem endless.

C.When there is money enough to satisfy one level of wants, another level appears.

D.There are several levels of wants in one’s life.

E.At this stage, we now may seek to ensure the health, safety, and leisure.

F.Also included here are fancy foods and the latest styles in clothing.

G.Different people have different wants on each level

After years of planning and months of expectations, the 2016 Summer Games finally began in Brazil on August 5. Over 10,000 athletes from 207 countries marched across Rio de Janeiro’s Maracana stadium, proud to represent their respective nations at the world’s most famous sporting event.

The road to the Olympics, however, is not easy for any athlete. It has been particularly hard for Yusra Mardini, who is a member of the world’s first “Olympic Refugee (难民)Team.” The 19-year-old always dreamed of swimming for Syria at the Olympic Games. However, in August 2015, after losing her home in the conflict that has involved Syria since 2011, she and her sister decided to flee the country. The sisters along with a few other Syrian nationals made their way to Turkey via Lebanon. They then set sail on a small boat to their final destination — Greece.

Unluckily, thirty minutes after leaving Turkey, the motor on the ship which was meant to hold six passengers but was instead carrying twenty, failed. Yusra, her sister Sarah, and the only two other strong swimmers aboard the boat had no choice but to dive into the ocean and use their superior swimming skills to push the boat and its passengers all the way to Lesbos, Greece – A journey that took three hours.

While her dream of representing her country was ruined, Yusra did not give up her desire to compete in the Olympics. In March 2016, she was one of ten athletes selected and funded by the Olympic Committee to form the first-ever “Refugee Team.” International Olympic Committee president Thomas Bach believes that Yusra and her teammates, who have also had to flee their countries, “Will show the world that despite the unimaginable tragedies they have faced, anyone can compete, anyone can contribute to society through their talent, skill, and strength of the human spirit.”
