Every time we get behind the wheel of a car, we put our lives and the lives of others at risk. Self-driving cars are designed to reduce those risks by letting technology control our vehicles.

    Accident rates for self-driving cars have been much lower than the rate, for human-driven cars. {#blank#}1{#/blank#}

    As humans, we can make moral choices in avoiding accidents. To avoid hitting a child, for example, human drivers might sharply turn a car away from the child even if others may be injured. {#blank#}2{#/blank#} Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

    {#blank#}3{#/blank#} You are shown two possible traffic situations and you choose between them. An accident will take place. You choose how many living beings would be hurt or killed.

    In one situation there may be a female doctor, a child, two dogs and a homeless person who would be killed. In the other situation, you might have two babies and a cat who would be killed. {#blank#}4{#/blank#}

    The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. {#blank#}5{#/blank#} At the end of the situation, you are shown the results, based on the choices you made. The results show which character you were most likely to save and which character you were most likely to have die.

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

    Just admit (承认）it. Don't think that our mistakes are caused by other {#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 u 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.

    Although most games have winners and losers, the goal of sports is not to win every game. The real goals include getting exercise, having fun, and learning important social skills, like sportsmanship.

    Good sportsmanship is all about respect. Good sports (具有运动家品格的人) respect the other players on their team. They respect he players on opposing teams. They respect coaches, and they also respect the referees or other officials involved in their games.{#blank#}1{#/blank#}they yell at their teammates and they talk back to coaches or referees.

    Kids usually learn sportsmanship - good and bad - from the adults in their lives.{#blank#}2{#/blank#}If parents and coaches show disrespect to other fans, referees, or each other, kids will likely act the same way on the field.

    {#blank#}3{#/blank#}Some of them are very basic and easy to do, like shaking hands with other players before a game. Other examples may take a little more courage, such as acknowledging a great play made by the opposing team.

    Why do we go to zoos? Millions of people around the world visit zoos each year, but the reason is hard to explain .{#blank#}1{#/blank#} But the animals they see in zoos are little like the toys, cartoons, and decorations that fill their homes. For such children, meeting with real animals can be confusing, even upsetting.

    The great interest that children have in animals today might lead one to suppose that this has always been the case. {#blank#}2{#/blank#}That was also when zoos became an important part of middle-class life.

    {#blank#}3{#/blank#}They lived together with our ancestors in a shared natural environment. In the Industrial Era, the human domination (支配)of animals could be seen in the popularity of real-looking animal toys. Children rode rocking-horses that had realistic features, and they slept with bears, tigers, and rabbits that looked and felt almost real. The Twentieth Century marked a further development--the change of animals into people.

    This was the age of Babar the Elephant, Hello Kitty, and the Lion King. Parents and children had previously wanted animals that looked like animals.{#blank#}4{#/blank#}.

    In a zoo they hope to see the living breathing versions of their character friends. They find instead unfamiliar creatures who cannot speak, smile, or interact with them. For this reason, a visit to the zoo can be disappointing for children today.{#blank#}5{#/blank#} Meeting real animals reminds us forcefully of the boundary between imagination and reality.

    When we visit animals in a zoo, perhaps we will recall our true relationship not only to animals but to the entire world.

A. Animals are the best friends of the human beings.

B. Most of children are looking forward to visiting zoos.

C. Perhaps that disappointment is the best gift a zoo can offer.

D. But now they want animals that look and act like humans

E. Yet, it was not until the Industrial Era that animals became part of childhood.

F. In prehistoric times, there had been no zoos, as animals were a real part of the human world.

G. Many of those visitors are children, whose lives are already surrounded by animals' images.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). {#blank#}4{#/blank#}. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on

Useful Memory Strategies

    Form associations between new and remembered information. {#blank#}1{#/blank#}, then you can increase the chance that new memories will be formed. Try coming up with a familiar picture, song, joke, or rhyme that you can associate with the new material. Form a picture in your mind that includes the new fact.

    {#blank#}2{#/blank#}. It may be boring, but simply repeating new information over and over in different ways will help it stick in your brain better, especially if you space out the repetition over time. For example, if you're trying to remember the definition of a new word, read it several times to yourself. Then speak the definition out loud a couple times, and try writing it down once or twice.

    Teach someone else the information you're trying to learn. Teaching others can help you remember and understand things better. Find a classmate or co-worker who needs to learn the same information, form a study group, and take turns teaching each other different concepts.{#blank#}3{#/blank#}!

    Test yourself after learning something new.{#blank#}4{#/blank#}. You have to actually practice finding the information from your memory in order to strengthen the connections within your brain. Be sure to immediately check your answers to make sure you've got them right. {#blank#}5{#/blank#}, you will be more likely to remember it incorrectly in the future as well, so instantly correct yourself and repeat the right answer a few more times.

A. If you answer something wrong

B. After the basic information is right

C. Repeat new facts as soon as you come across them

D. If you can link new ideas with previously established ones

E. Simply re-reading the same information isn't good enough

F. Then keep trying effective methods and cooperation with others

G. Alternately, ask your friends if they're willing to learn something new from you
