Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character,and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

        Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

        To answer these questions, Brooks surveys a wide range of disciplines（学科）. Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention.So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science.

    Many animals recognize their food because they see it. So do humans. When you see an apple or apiece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

    Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A land of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

    Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health Choosing the right food, therefore, has become an area of study in modern life.

    There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs. The satellite was directed into an area known as Manhattan. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information about the feasibility of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology. "We have come to the conclusion, based on last weeks satellite landing, "Prof. Zog said, that there is no life on Earth.”

    “How do you know this? "the science reporter of the Venus Evening News asked "For one thing, Earth s surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive. “Are there any other sources of danger that you have discovered in your studies?

    “Take a look at this photo. You see this dark black cloud staying over the surface of Earth? We don' t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

    “Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink.”

    “Sir, what are all those tiny black spots on the photographs?

We're not certain. They seem to be metal particles that move along certain paths. They give gases, make noise and keep crashing into each other.

    “Prof. Zog, why are we spending billions and billions of Zilches to land a flying saucer on Earth when there is no life there?"

    “Because if we Venusians can learn to breathe in the Earth atmosphere, then we can live anywhere.”

    Here are some great people and their achievements.

    Mary Anderson ­ windscreen wiper.

    Back on a freezing winter's day in 1902, Mary Anderson was travelling by train through New York City. Snow was falling, forcing the driver to stop repeatedly and get out to clear it. Each time the door opened, Mary suffered a gust of sub-zero air. She had an idea: why not make some kind of a rubber blade that could be operated from inside the vehicle? And that's exactly what she did.

    Josephine Cochrane ­ dishwasher

    The dishwasher dates back even earlier to the 19th century, and to the dinner parties thrown by a lady called Josephine Cochrane. As a frequent host, she wanted a machine that could wash dishes faster than people. Her response was to develop what was to become the first commercially successful dishwasher. Interestingly, innovation was in her blood: her grandfather had invented the steamboat.

    Stephanie Kwolek ­ Kevlar

    Kevlar is the lightweight fibre used in bulletproof vests. The material is used by millions every day and has saved countless lives. The super tough fabric is also used in objects ranging from gloves to airplanes. Incredibly, its strength-to-weight ratio(比强度) is five times higher than steel. Again, it was invented by a woman, the American chemist Stephanie Kwolek, in 1964.

    Grace Hopper ­ first compiler(编译程序)

    One of the most important inventions of the 20th century must surely be the computer programme. The world of programming is unbalanced in terms of gender. Men vastly outnumber women, and take home around 30% more pay than their female counterparts on average. But back in the 1940s and 1950s, women were at the forefront of this new field. Grace Hopper is credited with inventing the first compiler in 1952, which serves as the bridge between code and the binary(二进制的) ones and zeros understood by computers.

    For the past few months, my three-year-old daughter has spent an hour every week learning a foreign language. She walks into a small room in a local school, where she and a handful of three and four-year-old spend the next hour dancing to ^“La Vaca Lola”, a song about a Spanish cow, creating finger puppets(木偶) to voice what they like and don't like (me gusta, no me gusta) and shouting out which animals are big (grande) or small (pequeno).

    She tells us little about the classes. In fact, for the first few weeks, nothing at all. I begin to wonder if it was a huge mistake (each lesson works out at about £9) but then I show her “La Vaca Lola” on YouTube. She shouts vaca with enthusiasm and with what I hope is a Spanish accent.

    The wish to enroll(使……加入) her in language lessons came, like most things, gradually and then in a sudden rush. In my day job, I read and edit stories about the Chinese economy. For a long time, I felt that it would be good for her to learn another language but I had no great plan as to when.

    Then I read Edward Luce's The Retreat of Western Liberalism and all my thoughts and worry about the economy combined into a panic. Waking in a sweat, it seemed obvious that if my daughter was to have any kind of future, she would have to learn another language. Ideally (理想地) immediately.

    I thought about Mandarin Chinese, one of the top 10 languages most important for our future, according to the British Council (others include Arabic, French, German, Portuguese, Italian, Russian, Dutch and Japanese). But there were no classes for young children nearby. There were, however, local Spanish classes—the number-one language on the list. When she started to sing "Incy Wincy Spider" in Spanish and English—helped by a Spanish nursery worker-our decision was made.
