Back in the days when I wrote my first songs, I hated my voice. I saw myself as a songwriter and guitarist but never a singer! I continued to write songs, and to search for the perfect singer. After a few years I did discover a singer, so we started a project together. We held a few concerts, and put a lot of work into it. She forces me to sing some songs at concerts myself, so I started going to a bar to practice them. This was my first, small breakthrough.

One day she came round to my flat and informed me that she could no longer work with me, and also that the bar owner at the open mic venue(麦克风场地) had replaced us at short notice because some New York jazz star happened to be in town, and was available that evening to perform. The first bit of news made me sad and disappointed, but the second made me angry.

However, that same evening, with as much determination as I could muster (集合), I resolved to play three new songs at the bar, just as I had planned before. I was quite nervous, but I dragged myself down to the bar and sang those songs! I never felt so liberated(无拘束的). That night I couldn’t get to sleep. I was simply astonished, hardly believing that I was a person who acted so courageously, and that I’d been able to sing my songs myself.

Since then I’ve begun to encourage others to adopt a similar approach when they aren’t able to see their own potential. One example is an amateur fiddler (小提琴手) who could barely bring herself to lift her instrument to play in front of people. I forced her to ignore her fear, and simply get on with it. Now, a year or two later, she is a passionate, happy performer in front of any crowd!

Once you get the ball rolling in yourself, you can start inspiring those around you.

A new book called “Battle Hymn of the Tiger Mother” by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.

Many people are against Amy Chua’s parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.

Ms. Chua says after her younger daughter shouted “I hate my life! I hate you!” she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children’s abilities.

“The debate is about what it means to be a successful parent and what it means to be a successful child,” said Stacy DeBroff, who has written four books on parenting. She says Amy Chua’s parenting style is not limited to Chinese families. It is a traditional way of parenting among immigrants (移民). They hope to get a better future for their children.

She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.

4.In which part of a newspaper can you read the passage?

A. Business.B. Entertainment.C. Sports.D. Culture.

The Process of Ageing

At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the possibility of death is least. Earlier, we were infants and young children, and consequently more vulnerable (易受伤的); later, we shall undergo a progressive loss of our vigorous and resistance which, though vague at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us.

This decline in vigorous with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually “die of old age”, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer — on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and physically strong we are.

Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigorous with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things “wear out”.

Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound (上发条的) watch, or the sun, do in fact ran out of energy in accordance with the second law of thermodynamics (热力学). But these are not similar or equivalent to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself — it does not consist of living parts, only of metal, which wears away by friction (摩擦). We could, at one time, repair ourselves — well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power, an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

A. people usually are unhappy when they are reminded of ageing

B. children reach their full intelligence at the age of twelve years

As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free-form gestures–sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.

“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free-form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.

The researchers carried out a create-test-retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free-form gestures as passwords.

To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens（触摸屏）, attempt to steal a free-form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.

Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free–form passwords in the future. They believe this is the first study to explore free-form gestures as passwords. They will soon publish their findings.

1.What can we learn about free-form gestures?

A. They are improving mobile security in a way.

B. Users will have to make use of simple gestures.

C. They will never be copied by others.

D. Users must move their fingers in fixed shapes.

2.The experiment in paragraph 4 is to test _________ of free - form gestures.

A. templateB. applicationC. accuracyD. security

3.According to the text, the researchers think that ________.

A. it is easy to steal any password with a quick eye

B. better ways of setting passwords should be developed

C. people had better not use smart phones to pay bills

D. personal information should not be stored in a phone

4.The main purpose of the text is to ________.

A. advise people to use free-form gestures

B. discuss whether smart phones are safe

C. talk about the practicality of passwords

D. introduce the study of a new password

As the labor market becomes more attractive, more companies are sending their employees to school. Fiat Chrysler Automobiles is the latest company to use tuition assistance for employees — which for decades has been a part of many business’ benefits packages — as part of a renewed effort to bring in and cultivate talent. And while the impact of such programs has yet to be fully assessed, many see it as a positive — although gradual-movement.

“For workers, it gives them a better opportunity for development,” says Colleen Flaherty Manchester, a professor. “For firms, they are able to recruit the type of employees who have value education and are less likely to turn over, and thus have a higher level of retention(保留).”

In all, 56 percent of US organizations offer undergraduate educational assistance while 52 percent offer graduate assistance.

Largely driving the trend are Millennials, who happen to be the fastest-growing people in the US workforce today and to whom the idea of tuition support from employers is especially appealing. Nearly 60 percent of Millennials surveyed said they would choose a job with strong professional-development potential over one with regular pay raises. Employers are absolutely adapting to Millennials in the workplace. They recognize that they need more experience, more knowledge, more mentoring to be successful. And they’re asking for it.

Of more than 140,000 Starbucks employees, only about 4,000 have signed up for the company’s College Achievement Plan. What the long-term effects such programs might have for companies’ retention and turnover rates remain unclear. But, the pluses of these programs are more important than the minuses. We’re going to see a lot more of this in the future.

1.Using tuition assistance for employees ________.

A. has attracted a large number of talents

B. is a trend that formed recently

C. has existed for scores of years

D. is well received by employees

2.What can we learn from what Colleen Flaherty said?

A. It is merely beneficial to employees

B. It is a win-win event for employees and employers.

C. Valuing education has become a trend for all companies.

D. It turns out to be tough for firms to find suitable employees.

3.What does the underlined word “it” in Paragraph 4 refer to?

A. regular pay raises.

B. more chances to be successful

C. educational support

D. professional–development potential

4.Which of the following statements is TRUE about the programs?

A. The programs can guarantee the employees a good job.

B. The impact of the programs remains to be estimated.

C. Employees will benefit more from the programs than companies.

D. It’s less likely that employees will remain in the same company after receiving the programs.

Age has its privileges in America, and one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age — in some cases as low as 55 — is automatically entitled to dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one’s need but by the date on one’s birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses — as common as color televisions in motel rooms and free coffee on airliners.

People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent(有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous (同义的). Perhaps that once was true, but today elderly Americans as a group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor. But most of them aren’t.

It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between the generations.

Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involve a transfer of resources from the young to the old. Employment is another sore point. Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job — thereby lessening employment and promotion opportunities for younger workers.

Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don’t need them.

It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can’t take care of themselves and need special treatment; and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against — discrimination by age.
