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.

    Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    {#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

    For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#}

    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

    {#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “{#blank#}4{#/blank#} Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}

A. In general the person feels excited and ready to act

B. They said that laughter is much healthier than anger.

C. Expressing anger violently is more harmful than repressing it

D. Anger may cause you a cancer.

E. Do not express your anger while angry.

F. Anger is a normal emotion that we all feel from time to time

G. Doctors say the solution is learning how to deal with anger.

    Be careful what you say around your dog. It might understand more than you think.

    A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

    In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

    In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

    The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.

    Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种) known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

    It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

    Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space instead of on conditions and people on Earth? These are questions that, understandably, are very often asked.

    Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? With the wide spread of a species, human beings can get high chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

    Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

    Exploration also allows minerals and other potential resources to be found. Even if we have no need of them right now, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spinoffs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even nonstick pans and mirrored sunglasses are byproducts of technological developments in the space.

    While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

    While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

    We are surrounded by messages trying to get our attention. Advertisers, politicians and other groups all try to get us to agree with them.{#blank#}1{#/blank#}. Propaganda is not always a bad thing, but it often hides the truth about a topic. It's very similar to advertising, whose goal is to get people to buy something, while propaganda is to change what people believe.

    Propaganda Techniques

    To create propaganda, a common technique is name－calling. A politician might call someone a traitor or liar, which makes the other person look bad. Another is the trend technique. People want to be on the side in the favor.{#blank#}2{#/blank#}. Some propaganda is based on fear. It scares people into choosing a certain side or taking action, which might not be bad. Anti－smoking campaigns are one example. They may scare people into thinking that if they smoke, they will get cancer.

    {#blank#}3{#/blank#}.

    Propaganda is used by many groups, such as businesses, politicians and the government. It is spread through posters, television and radio. The Internet makes it easy to send messages to the whole world.

    Types of Propaganda

    Political propaganda has been around as long as there have been politicians.{#blank#}4{#/blank#}. People have used it for many years. War propaganda began during World War I, more than 100 years ago.

    To see if propaganda is saying the truth, people need to do extra work. For example, ads might always sound like they're true. But before you believe them, try to think about who created and paid for them. Find out why they did it.{#blank#}5{#/blank#}.

A. Propaganda Targets

B. Propaganda Mediums

C. Another word for this is propaganda

D. So most people will agree with those politicians

E. Then, you can decide if they're being honest or not

F. However, religious propaganda was actually the first official one

G. People might join someone who claims to be popular or winning

    Education has always been a hot topic. How to educate children can be a sweet but painstaking task for parents, many of whom try to offer their children the best environment. Competition between parents over children's education may start from the kind of animated (动画) series children watch. {#blank#}1{#/blank#} By watching the former, children can learn English at the same time. However, this does not mean those watching foreign shows perform better than those watching Chinese ones. {#blank#}2{#/blank#} They can help children learn traditional Chinese culture and history. Take Journey to the West for example. {#blank#}3{#/blank#}

    By watching this show, children can learn more about the history of the Tang Dynasty and the development of Buddhist culture in China. Foreign shows can open a window for children to gain a better understanding of the outside world. So, children ought to be encouraged to watch both as long as the content of the show is beneficial.

    This can also be applied to other things beyond animated series. {#blank#}4{#/blank#} However, some parents fail to do this. Their incorrect view can more or less leave an influence on their children. Innocent (天真的) children, influenced by their parents, slowly hold the view that watching foreign shows is better than watching Chinese shows. {#blank#}5{#/blank#}

A. Chinese shows have their own advantages.

B. Foreign animated series are always the first choice for parents.

C. Children often follow their parents' advice when choosing animated series.

D. For example, children can be encouraged to read folk tales at home and abroad.

E. Once the view is formed in children's minds, parents' education proves a failure.

F. This show is based on one of the four great classical novels of Chinese literature.

G. For some parents, watching foreign animated shows is better than watching Chinese ones.
