Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying. {#blank#}1{#/blank#} However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace (支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

    Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position.

    Undo your seatbelt. {#blank#}2{#/blank#} Untie the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.

    {#blank#}3{#/blank#} Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.

    Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. {#blank#}4{#/blank#}

    Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. {#blank#}5{#/blank#} While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. Surviving a sinking car is not as difficult as you think.

C. It takes 60 to 120 seconds for a car to fill up with water usually.

D. Such accidents are particularly dangerous to the risk of drowning.

E. In conclusion, if you know what to do in the water, you will be safe.

F. This is the first thing to attend to, yet it often gets forgotten in the panic.

G. But the sooner the window is open, the sooner you can escape directly through it.

    Lazy people will never achieve anything in life. However, laziness can be defeated once a few changes have been made in your mind.

    {#blank#}1{#/blank#} Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting yow sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.

    Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from project to project. Others take a more proactive approach, viewing each project or task as a challenge they must overcome alone. {#blank#}2{#/blank#} 

    Some people fight laziness by removing the temptations that surround them. A television in the living room may provide entertainment, but watching too much TV often promotes laziness {#blank#}3{#/blank#} Complete a certain number of chores and reward yourself with a good dinner or a film.

    Laziness can also be a lasting problem at home. Couples and children may all have different energy levels, but laziness can be spread if not dealt with quickly. {#blank#}4{#/blank#} Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own chores. It is difficult to practice laziness when you are surrounded by motivated people.

    {#blank#}5{#/blank#} Enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help boost your mood.

A. Knowing how to fight laziness is important.

B. Om way to fight laziness is to get enough sleep.

C. Finally, taking exercise regularly can help you fight laziness.

D. With strong determination, you will be able to achieve your goal.

E. Laziness sets in when you no longer feel in charge of your own life.

F. Create a reward system for yourself, just as parents do for the children.

G. To fight household laziness, set an example.

    Have you ever imagined the benefits that a good memory can bring to you? {#blank#}1{#/blank#} Here are four ways to improve your memory.

    {#blank#}2{#/blank#} There is evidence that sleep plays a vital role in the consolidation of memories relating to learning motor skills, such as learning to play a musical instrument or ride a bike. Having a full night's sleep soon after gaining a new skill helps consolidate the processes involved, so they can later be performed well.

    It's rewarding to continue education. Older people are often told to adopt a “use it or lose it” approach to maintaining cognitive (认知的) function. {#blank#}3{#/blank#} In a 2016 study, US researchers found participants aged 60-90 who spent 15 hours a week for three months learning a complex skill, such as digital photography, saw significant improvements in memory tests.

    Taking a break counts. {#blank#}4{#/blank#} More than a century ago, German scientists showed that people performed almost twice as well in memory tests if they took breaks.

It's useful to stay social. Having an active social life delays memory loss as we age, US scientists who asked people in their 50s and 60s to do memory tests every other year between 2001 and 2007 found the decline in recall abilities of their most sociable subjects to be half that of the least well connected. {#blank#}5{#/blank#}

A. Sleeping well helps strengthen memories.

B. Old people should participate in easy activities

C. Yoga, meditation or other relaxation techniques may help.

D. Memories can be destroyed if the brain doesn't have enough rests to sharpen them.

E. In fact, when it comes to memory, research suggests that only certain types of mental activities help.

F. Being able to remember important pieces of information can give you a powerful advantage in your life.

G. Having good friends, volunteering for charities and other forms of social engagement also protect memory.

    Why Stand in Line on Black Friday?

    Standing in line is a pain. At the post office. At the box office. At a restaurant.{#blank#}1{#/blank#}The first spot outside some Best Buy stores is usually claimed (认领) weeks in advance, often by a person in a tent. Shoppers at Walmart will print out maps of the store, with circles around their primary targets.{#blank#}2{#/blank#}

    "These queues are quite different than the usual annoying ones we come across day to day at the ATM or in the subway," said Richard Larson, a professor at MIT who has spent years studying line behavior. "Once a year," he said, "the lines are exciting. They're the kind you might tell your grandchildren about."{#blank#}3{#/blank#}Billie LeClere, 45, was first in line on Thursday at Walmart in Manchester, Iowa. She said she was a regular Black Friday shopper. But this year, she came with a specific purpose: to get a good deal on a new TV. She and her husband had recently separated, and he had taken the old TV earlier that day. "The marriage died, not the TV," she said.{#blank#}4{#/blank#} "It's going to be nice to have something that's newer-and it's mine, not his."

    {#blank#}5{#/blank#}The following are two of the typical results. The "gotta have it" atmosphere makes people more anxious. Sometimes the behaviour of the queue turns violent. Therefore，lines test patience，personal space especially on Black Friday, when the crowds can be overwhelming (势不可挡的).

A. Shoppers are excited to buy gifts.

B. But on Black Friday, it's an experience.

C. Moreover, the crowds are queuing for good deals.

D. Many families are queuing to chat with each other.

E. The experience gave her a sense of accomplishment.

F. They are trying to turn the experience into an adventure.

G. The behaviour of people in lines has inspired decades of research.

    "Life is speeding up. {#blank#}1{#/blank#}." Picture this: You're rushing to finish your homework on the computer. Your mobile phone rings. Suddenly the computer blanks and you lose all your work. Now you have to stay up to get it done. {#blank#}2{#/blank#}.

    {#blank#}3{#/blank#}. Due to these inventions, we are often left feeling stressed and tired. Why do you think people who live far away from noisy cities often seem to be happier? Perhaps because they lead a simple life.

    One family in the UK went "back in time" to see what life was like without all the inventions we have today, The grandparents, with their daughter, and grandsons Benjamin, 10 and Thomas, 7, spent nine weeks in a house dating back to 1940. {#blank#}4{#/blank#}.

    The grandmother, Molly, said, "It was hard physically, but not mentally." She believed life was less materialistic. " {#blank#}5{#/blank#}." she said. The boys said they had less to fight over, their computer, for example. Benjamin also noticed that his grandmother had changed from being a trendy, beer —drinking granny to one who liked cooking things.

A. Are you faced with a completely different situation?

B. Hardly can you succeed in doing something in a perfect way

C. Everyone is getting unwell

D. How can you feel calm and happy?

E. Inventions have speeded up our lives so much

F. They had no microwave, computer or mobile phones

G. The more things you have, the more difficult life becomes

In 1985, 16-year-old Douglas Casa, ran the championship 10, 000 meter track race at the Empire State Games. Suddenly, with just 200 meters to go, he collapsed on the final straightaway, with his body temperature at dangerous levels. He had suffered an exertional heat stroke（运动型中暑）or sunstroke. {#blank#}1{#/blank#}

From ancient soldiers on the battlefield to modern warriors on the gridiron（足球球场）, exertional heat stroke, has long been a serious concern. And unlike classical heat stroke, which affects people such as babies and the elderly during heat waves, exertional heat stroke is caused by intense exercise in the heat. {#blank#}2{#/blank#}

So how do you diagnose an exertional heat stroke? The main criterion is a core body temperature greater than 40℃ along with signs of central nervous system disfunction such as confused behavior, or loss of consciousness. 

As far as treatment goes, the most important thing to remember is cool first, transport second. The human body can withstand a core temperature above 40℃ for about 30 minutes before cell damage sets in. {#blank#}3{#/blank#}After any athletic or protective gear has been removed from the victim, place them in an ice water tub while stirring the water and monitoring vitals continuously. {#blank#}4{#/blank#}As you wait, itˈs important to keep the victim calm while cooling as much surface area as possible until emergency personnel arrive. If medical staff are available on site, cooling should continue until a core temperature of 38. 9℃ is reached. 

{#blank#}5{#/blank#}As Dr. J Levick wrote of exertional heat stroke in 1859, "It strikes down its victim with his full armor on. Youth, health and strength oppose no obstacle to its power. " But donˈt be frightened so much for it has been 100% survivable with proper care.
