As we know, everyone can make mistakes, but don't worry about it. The following is what we should do when we make mistakes.

    ● Just admit (承认）it. Don't think that our mistakes are caused by others. {#blank#}1{#/blank#} Don't blame other people, and don't cheat ourselves, either.

    ●{#blank#}2{#/blank#} In order to stop the problem from getting worse, we should act quickly to solve it. If we don't act and deal with the problem quickly, it'll only make us feel more stressed. Also it is necessary to make a plan of action and correct the mistake according to it. {#blank#}3{#/blank#}

    ●{#blank#}4{#/blank#} Those who have made the most mistakes can get an A, for they are the ones who have learned the most. The more we learn from our mistakes, the cleverer we are.

    ●{#blank#}5{#/blank#}What caused us to make the mistake? How can we avoid making the same mistake in the future? When we act with a method to get a good result, do it that way next time. If we don't, we should stop, think about it, change it and try again.

A. Don't be afraid of failure.

B. Realize that making mistakes is the best way to learn.

C. Solve it at once.

D. Be brave and face the fact that we have made the mistakes.

E. So be away from stress.

F. Think about what we can learn from our mistakes.

G. So decide quickly and act.

    When you sit down, you pick it out. When you are in your car, you reach for it．When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it．

    Cigarettes? Cup of coffee? No, it's the third most addictive thing in modern life, the cell phone．And experts say it is becoming more difficult for many people to curb their desire to hug it more tightly than most of their personal relationships．

    With its shiny surface, its smooth and satisfying touch, its air of complexity, the cell phone  connects us to the world even as it disconnects us from people three feet away．In just the past  couple of years, the cell phone has challenged individuals, employers, phone makers and  counselors（顾问）in ways its inventors in the late 1940s never imagined．

    The costs are becoming even more evident, and I don't mean just the monthly bill．Dr．Chris  Knippers, a counselor at the Betty Ford Center in Southern California, reports that the overuse of  cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality．

    Sounds extreme, but we've all witnessed the evidence: the person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him．

    Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?

    Jim Williams, an industrial sociologist based in Massachusetts, notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation．He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with．Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says．

    If the cell phone has truly had these effects, it's because it has become very widespread．Consider that in 1987, there were only 1 million cell phones in use．Today, something like 300 million Americans carry them．They far outnumber wired phones in the United States．

                                       Cell phones：Is there a cancer link?

    Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.

    Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia (白血病). Also there's a greater than 90 percent chance that cell phones can cause brain tumors. “It's apparent now that there's a real risk, ”said Carpenter.

    But others believe these concerns are not justified. Dr Martha Linet, head of radiation epidemiology (流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don't support warning labels for cell phones, ”said Linet. “We don't have the evidence that there's much danger.”

    Studies so far suggest a weak connection between EMFs (电磁场) and illness—so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It's funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cell phone use and cancer risk.

    Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card(信用卡). Instead, he has been told to wait another two years, until he is 18.

    The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David's firm releases(推出) two new games for the fast throwing computer market each month.

    But David's biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage(抵押贷款), or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. "I got the job because the people who run the firm knew I had already written some programs," he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. But most of his spare time is spent working.

    "Unfortunately, computing was not part of our studies at school," he said. "But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway." David added: "I would like to earn a million and I suppose early retirement(退休) is a possibility. You never know when the market might disappear."

    Each year, hundreds of thousands of wild animals around the world are killed in trophy hunting—the organized shooting of animals for pleasure. The hunters then bring parts of the animal home with them as their "trophy" to remember the hunting.

    Trophy hunters pay big money to kill animals. Some of the money goes to helping wildlife protection. Trophy hunting also attracts business, which encourages people to preserve land and breed(饲养) animals that would otherwise be endangered. Cathy Dean, head of the Save the Rhino Charity, says that at the start of the 1900s there were only 50–100 southern white rhinos. Now, there are around 18,000. This is partly because some of them were raised specially for trophy hunting.

    But things don't usually go on one way. According to WWF, elephant populations have fallen from 1.3 million to just over 400,000 since the 1980s. Over the same period, hunters from around the world have taken home more than 100,000 African elephant trophies. Trophy hunting is not illegal(非法的) but unfair on the animals. In 2015, Cecil the lion was shot by a US trophy hunter. Cecil was a beloved lion in Zimbabwe, Africa. Cecil was lured with bait(诱饵), shot with an arrow and struggled in blood for more than ten hours before his hunters tracked and finished killing him. His son, Xanda, met a similar fate two years later.

    Cecil's death caused worldwide outrage and protests(反抗) against trophy hunting. Countries including Australia, France and the Netherlands banned(禁止) the import of lion trophies—they stop hunters from being allowed to bring home parts of the animal they kill. They believe that people will stop trophy hunting because the activity might lose its attraction if hunters can't bring their trophies home.

    The UK Government said that it would consider a ban on trophy-hunting imports by 2017, but no action had been taken. In April 2019, a letter by protesters against trophy hunting was sent to the UK government asking to ban trophy-hunting imports. On 7 May, the official in charge of the environment, Michael Gove, said that the UK would not ban the imports for the time being. This left the world in a state of a shock. Hopefully the UK will place a ban on trophy-hunting imports, which would be an important message and inspire others to treat animals better. We're waiting for the day to come.

    Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people in face of a technological shift.

    It is not always the case, though. When you look at attitudes toward driverless cars, there doesn't seem to be a clear generational divide. The public overall disagree on whether they'd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not.

    The fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now——and no one can get one yet ——but among those who are open to them, every age group is similarly engaged.

    When it comes to driverless cars, differences in attitude are obvious based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education: 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less.

    Where a person lives matters, too. More people who lived in cities and suburbs said they wanted to try driverless car than those who lived in rural areas.

    While there's reason to believe that interest in self-driving cars is going up, a person's age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually available for sale, the early adopters will be the people who can afford to buy them.
