Your next car might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

    Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（统治的）are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

    Driverless cars will reduce accidents by around 90 percent. That's big—the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

    On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

    Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

    A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.

    Eyesight plays a very important role in our daily life. Every waking moment，the eyes are working to see the world around us. Over forty per cent of Americans worry about losing eyesight，but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule yearly exams{#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays(紫外线)．Long­term stay in the sun creates risk to your eyes. No matter what the season is，it's extremely important to wear sunglasses.{#blank#}2{#/blank#}  Give your eyes a break. Two­thirds of Americans spend up to seven hours a day using computers or other digital products.

{#blank#}3{#/blank#}Experts recommend that people practise the 20/20/20 rule：every 20 minutes，take a 20­second break and look at something 20 feet away.

    {#blank#}4{#/blank#}As part of a healthy diet，eat more fruits and vegetables each day. Vitamins(维生素) C and E help protect eyesight and promote eye health.

    Practise safe wear and care of contact lenses(隐形眼镜)．Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses，many are breaking the rules and putting their eyesight at risk.{#blank#}5{#/blank#} Otherwise，you may have problems such as red eyes，pain in the eyes，or a more serious condition.

A．This frequent eye activity increases the risk for eye tiredness

B.  Eye care should begin early in life.

C．Eat your greens.

D．They can properly protect your eyes.

E．Stay in good shape by taking more vitamins.

F．Parents usually don't care about their own eyesight.

    A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love(早恋)may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

    The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study，even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to their parents.

    Dr Marianm Kaufman，an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build b friendships and a b sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

    Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity(成熟)gives us a chance to avoid its bad side effects.

    The favorite food in the United States is the hamburger, a kind of round sandwich of cooked beef.{#blank#}1{#/blank#}At fast food restaurants, people order their food, wait a few minutes, and carry it to their tables themselves. People also take their food out of the restaurant and eat it in their cars or in their homes. At some fast food restaurants, people can order their food, pay for it and pick it up without leaving their cars.

    {#blank#}2{#/blank#}Most of them sell hamburgers, French fries and milkshakes, which are traditionally popular foods among Americans. In addition, there are many fast food restaurants that serve Chinese food, Mexican food, Italian food, chicken, seafood and ice cream.

    A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度)of yellow makes it easier for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Ho. To test whether there was a causal relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    The researchers also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio(比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents would occur per month or 917 fewer accidents per year. Assuming an average repair cost of $1,000 per car and a downtime of six days, switching the color of all taxis to yellow could produce an annual savings of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For instance, we hope to compare the accident rates of yellow school buses against other colors to find out if yellow is indeed a safer color for school buses. Besides, we are also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors," explained Prof Ho.

Rising through stages to realize ourselves

    Many modern people have the problem that they don't know who they are and what their purpose is. {#blank#}1{#/blank#} Once high school seniors graduate, they seem to lose their identity. They once studied hard. But after they stop working, they begin to lose their way.

    In the theory of the Hierarchy of Needs（需求理论）, Abraham Maslo, put forward a similar situation, which consists of the five levels of a person's need. The fifth and final level is self-realization, which is where our final achievement lies. {#blank#}2{#/blank#}.

    I think self- realization has three major aspects. The first stage is acceptance, the second stage is discovery and the last stage is perseverance.

    Acceptance is the first stage. We should be reminded that we are all born unique, so we all have our own strengths and weaknesses. Only when we understand these, can we pursue them or change them. {#blank#}3{#/blank#}.

    Once we've accepted ourselves, we can discover what we are interested in and what we want to be. {#blank#}4{#/blank#} but indeed we should live for ourselves. So before we start working towards a purpose, we should ask ourselves "Is this what we truly desire?" and "Is this going to change the situation we're in?"

    The last stage is perseverance.{#blank#}5{#/blank#}. Those who can self-realize are people who focus on the things they want to change.

    Through the three stages, we could gain recognition of ourselves. And by this point, whatever our lives were like, we would be able to stand tall, confident of ourselves.

A. It's nothing to a man of perseverance

B. Only by acceptance of the past can we change it

C. This is especially common among college students

D. Many people tend to go along with social expectations

E. Being objective and yet tolerant is the key to acceptance

F. It is the process of knowing ourselves and finding a purpose

G. Exploring our potential isn't going to be done in a short time
