【推荐2】A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion(万亿) connections in the brain of a three-year-old child.

Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern “A-B-B”. Another order was mu-ba-ge. This is the pattern “A-B-C”. The images showed that the part of the brain responsible for speech was more active during the “A-B-B” pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

Gervain is excited by these findings because the order of sounds is the building block of words and grammar. “Position is key to language,” she says. “If something is at the beginning or at the end, it makes a big difference: ‘John caught the bear.’ is very different from ‘The bear caught John.’”

Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones—no matter how educational—doesn’t appear to be enough for children’s brain development. They carried out a study of nine-month-old American babies. They expected the first group who’d watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies—regardless of whether they had watched the video or listened to the audio—learned nothing.

【推荐3】Technology is the application(应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via(通过) medical technology.

Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics(统计) show that the United States is continuing to pump billions of dollars annually(每年) into such efforts. So while we are running out of some scarce resources(少的资源) we may well find technological substitutes(代用品)for many of them through our research programs.

Therefore, in the final analysis the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.

【推荐1】You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

If it weren’t for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness(意识) of the dangers of pollution and the harmful effects of chemicals on humans and on the world’s lakes and oceans.

When Sandra Day O’Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and in 1981, the first woman to join the U. S. Supreme Court (最高法院). O’Connor gave the deciding vote in many important cases during her 24 years on the top court.

On December 1,1955, in Montgomery, Alabama, Rasa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott (抵制). It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” said Parks.

【推荐2】Jack lay, quiet and unmoving for thirty minutes while a stranger repeatedly stabbed (刺) him with sharp needles, causing blood to pour steadily out of his leg. Jack was getting a tattoo (纹身). His friend Tony had recently gotten a tattoo, and Jack was so impressed by it that he decided to get one too. Peer pressure, media influence, and personal expression are some of the common reasons for wearing tattoos today.

The desire to be accepted by one’s friends or peers can have a great influence on what a person does. Sometimes, wearing a tattoo can be a sign that you belong to a certain group. Gangs often use special clothes and tattoos to identify their particular group. Some of these groups wear only brand-name clothes. Others wear tattoos. When a person’s friends are all doing something, that person is more likely to do the same thing.

The media is another big influence behind the popularity of tattoos in North America. A wide variety of media images show tattoos－people appearing in commercials selling expensive cars, famous sports heroes with tattoos in magazines, fashion models wearing designer clothes that show their bodies tattooed with detailed and colourful patterns. These media images link tattoos to ideas of wealth, success, and status. As a result, many people decide to get a tattoo for its fashion and status value.

Many people decide to wear tattoos in order to express their artistic nature, their beliefs, or their feelings－in other words, to show their individuality. A musician in a rock band may get a tattoo of a guitar on the arm. Some environmentalists may tattoo pictures of endangered animals on their shoulders. A tattoo can be a public sign to show what is important in a person's life.

As you can see, there are many reasons why young North Americans get tattoos. A tattoo can be part of a group's uniform, a sign of fashion or an expression of individuality. The decision to get a tattoo is most often a result of the influence of friends or media or the desire to express oneself. For Jack, it was a mixture of all three.

【推荐3】“Funny”, a made-in-China emoji, seems to have recently moved beyond China. Now, it is more than an emoji, but a cultural expansion.

A series of “funny” emoji-based bolsters (抱枕) have attracted the attention of Japanese customers. Even if one bolster is more than three times as expensive as in China, it doesn’t kill their desires to buy it. One Japanese customer Miki said, “They are just so cute and I bought three bolsters at one time for my family. And every time I see them, my mood just brightens suddenly.”

A Japanese netizen Kiro Kara said, “I think the emoji implies very complicated meanings. My dad will send it when he doesn’t agree with someone but he has to say something and behave politely.”

Compared with Japanese impressions of the “funny” emoji, Chinese netizens prefer to use emoji to tease one another on social media.

One commonly seen online comment is, “We strongly suggest stopping the usage of the emoji. Because every time other people send me the emoji, I feel very uncomfortable and consider myself as a fool.”

Regarded as the most popular emoji, the “funny” emoji has received much attention since its release in 2013. In fact, the “funny” emoji is the updated version of its original one; “funny” has a smiley mouth, two eyebrows and a naughty look. All these characteristics present users a sense of satire (讽刺).

It's not the first time the Chinese emoji takes the world stage. Earlier this year, one emoji from the Chinese basketball celebrity Yao Ming has been spread through the Middle East region. In a city in southern Egypt, Yao’s smiling emoji has appeared frequently in local traffic signs to remind people the road ahead is one-way. Many locals do not know Yao Ming but are familiar with his emoji and nickname “Chinese Funny Face”.

As a new online language, emojis have become a necessary part of people’s daily life, helping people express their views in a more vivid and precise way. Also, it can help foreigners learn about Chinese culture. But how to properly use “the fifth innovation in China” without hurting others and turn them into commercial advantages still need answers.
