Conventional wisdom is a major barrier to innovation that threatens the survival of companies everywhere. It's based on the assumption that old ideas will always work, so they shouldn't be challenged. While this may be a valid assumption in situations that don't change, it's unlikely to hold true in a changing situation. In today's rapid changing global environment, old methods often don't work, and stubbornly using them can lead to major problems.
Most people seem to agree with conventional wisdom because it gives one a false sense of security. If everyone else believes it, then it must be true.Individuals who use conventional wisdom are certain that they are right, and being right is good.They want to continue using old ideas rather than take risks with changes that might not work.In 1977, Ken Olsen,co-founder and CEO of Digital Equipment Corporation(DEC), stated"There is no reason for any individual to have a computer in his hoe." Despite being a dominant leader in the computer industry, DEC no longer exists.
People seem to forget that since innovation is a change, there can be no inovation without change. Unfortunately, conventional wisdom prevents leaders, followers and companies from changing and therefore innovating. If companies don't innovate, but their competitors do, the future is likely to be problematic. Breaking from conventional wisdom has led to many of the most innovative companies and products in history across many industries, so it has a powerful effect on business success.
Ted Turner(founder of CNN) knew little, if anything, about the news business, but he knew it was inconvenient to watch news only at the dinner hour, as was common before CNN. Turner's solution was to create a cable channel dedicated to news 24 hours a day. The news establishment reflected conventional wisdom at the time, and predicted his idea would fail because no one wanted to watch the news all day.
However, it doesn't take a rocket scientist to understand that viewers don't have to watch the news all day for the CNN to work. Viewers just have to watch when they want to get information. Due to conventional thinking, the critics failed to recognize the opportunity that was clear to Ted. They assumed that only what was familiar to them could work in the future.
Conventional wisdom prevents creativity, flexibility and risk-taking, so unconventional leaders enthusiastically break from it. To survive, thrive and maintain competitive advantage, companies must be flexible when reacting to change.

Our most commonly held code for success is broken. Conventional wisdom holds that if we work hard we will be more successful, and if we are more successful, then we’ll be happy. If we can just find that great job, win that next promotion, lose those five pounds, happiness will follow. But recent discoveries in the field of positive psychology have shown that this code is actually backward: Happiness fuels success, not the other way around. When we are positive, our brains become more engaged, creative, motivated, energetic, and productive at work. This discovery has been repeatedly borne out by rigid research in psychology and neuroscience(神经学), management studies, and the bottom lines of organizations around the globe.
In The Happiness Advantage, Shawn Achor, who spent over a decade living, researching, and lecturing at Harvard University, draws on his own research—including one of the largest studies of happiness and potential at Harvard and others at companies like UBS to fix this broken code. Using stories and case studies from his work with CEOs of Fortune 500 in 42 countries, Achor explains how we can reprogram our brains to become more positive in order to gain a competitive ability at work.
Based on seven practical, actionable principles that have been tried and tested everywhere from classrooms to boardrooms, stretching from Argentina to Zimbabwe, he shows us how we can capitalize on the Happiness Advantage to improve our performance and maximize our potential.
A must-read for everyone trying to stand out in a world of increasing workloads and stress, The Happiness Advantage isn’t only about how to become happier at work. It’s about how to acquire the benefits of a happier and more positive mode of thinking to achieve the extraordinary in our work and in our lives.
1.Which of the following is the traditional code for success?
A. Hard word→success→happiness.
B. Success→happiness→hard word.
C. Happiness→hard word→success.
D. Hard work→ happiness→success.
2.What do we know about the new discovery in paragraph 1?
A. Conventional code for success is totally useless.
B. The more we are successful, the happier we are.
C. Positive psychology is really backward.
D. Happiness contributes greatly to success.
3.Why did the writer write the book The Happiness Advantages?
A. To reprogram one’s brain to be healthier.
B. To make people more positive and competitive.
C. To study stories and cases of CEOs.
D. To make a lecture at Harvard University.
4.The underlined phrase “capitalize on” in paragraph 3 is closes in meaning to ____
A. provide fund for
B. make full use of
C. write big letters for
D. stand out in
5.What is the purpose of the writer in writing the passage?
A. To help people stand out in the world.
B. To arouse people’s sense of happiness.
C. To help people decrease the work stress.
D. To strongly recommend the book.

Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children’s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging (过早老化).
Scientists measured this by studying the ends of children’s chromosomes (染色体), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.
Telomeres are special DNA sequences (序列) which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.
Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.
In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children’s telomeres—in cells obtained from the insides of their cheeks—at ages 5 and 10.
Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.
Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.
The study confirms a smallbutgrowing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.
1.The new study has found that ________.
A. violence leaves scars on a child’s mind
B. violence can speed up a child’s aging
C. hardship can change a child’s aging
D. hardship has a long-term effect on children
2.According to the text, telomeres ________.
A. probably cause a cell to divide quickly
B. can help prevent DNA from separating
C. can make a cell die quickly
D. become shorter before they die
3.All of the following things can shorten telomeres EXCEPT ________.

4.Which of the following is TRUE, according to the text?
A. Researchers measured the children’s telomeres from their legs in the study.
B. Kids interviewed in the study are exposed to two or more types of violence.
