Every time we get behind the wheel of a car, we pt 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. 1.

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. 2. Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

3. . 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. 4.

The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. 5. 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.

A. Who should those victims be?

B. Then the next situation appears.

C. You choose who lives and who dies.

D. You can use the Moral Machine to be the judge.

E. But what moral choices can self-driving cars make?

F. The Moral Machine website lets you choose how you would react in a collision.

G. Google’s self-driving car has had only 13 collisions after traveling 1.8 million miles.

Recently my husband had his Achilles tendon(跟腱) cut when feeding a chicken. When sitting in the doctor’s office waiting for surgery stressfully, I decided to treat myself for a minute and start to read about “The Little House on the Prairie”. Suddenly I felt my life seemed like a slack(懈怠) compared to the Ingalls who do all their washing and cooking but they feel so happy. Their every happiness is created from the work with their own hands. Yet I’m walking around feeling sorry for myself because I’m picking up the slack! So I’m thinking “Work it out! Get up and get busy.”

It really is true. I realize that I’m happiest when accomplishing tangible(有形的) productive work—working in the yard and washing my dishes—brings me happiness. This does not surprise Kelly Lambert Ph.D. She has been researching the phenomenon she calls “effort-rewards”. When you do meaningful work with your hands, a kind of neurochemical feedback floods your brain with dopamine and serotonin. These happy brain chemicals are natural antidepressants, and we’ve evolved to release them both to reward ourselves for working with our hands and to motivate ourselves to do it some more. Dr. Lambert says Americans have become more depressed in recent years and at the same time we’ve experienced a decrease in purposeful physical activity. Did we lose something vital to our mental health when we started pushing buttons instead of ploughing the fields?

Dr. Pansinski says she gets that happy look when she prepares a meal at the end of a day. “We are programmed to reward ourselves when we accomplish things with our hands. For so many people, it just feels as though everything’s going so fast—life, kids, hundreds of e-mails a day. There is so little you can really see and hold on to. Working with one’s hands is a way to slow down, to take pleasure in life again.”

1.Before reading “The Little House On the Prairie”, the writer might think the Ingalls were ________.

A. unknown B. hardworking

C. foolish D. unhappy

2.The writer develops the first paragraph in a way of ________.

A. giving an example B. making a comparison

C. analyzing a cause D. asking a question

3.From Kelly Lambert Ph. D, we know that ________.

A. her “effort-rewards” is popular among American people

B. working with our hands makes our brain tired easily

C. a decrease in physical work causes people in low mood.

D. we should work with our hands instead of using machine

4.From what Dr. Pansinski says, we can conclude that ________.

A. time and tide wait for no man

B. we should lower our expectation for life

C. it’s better to leave today’s work to tomorrow

D. we should never hurry our life too much

Parents may think they’re smart about where they store medicines, but their kids are smarter. Nearly 60,000 young children are rushed to the hospital every year after getting into medicines not meant for them, according to a new report from Safe Kids Worldwide.

The report finds little connection between what parents know about storing medicines safely and what they actually do. Nine out of 10 parents know that medicines should be stored up and away out of reach and sight, but 7 out of 10 of them admit not doing that. They leave medicines out on kitchen counters, sinks and sofas, believing babies and toddlers(学步者)aren’t tall enough or strong enough to reach them. Unfortunately, they probably can. Children as young as a month have ended up in an emergency department because they’d been poisoned by getting into a medicine that was left within reach.

Most poisonings related to medicines---particularly among babies and toddlers---occur within their home. Kids develop rapidly and they want to explore their environment. At certain ages they have a lot of hand-to-mouth activity, and so it’s very common for them to explore their environment and then try to taste what they find.

The new Safe Kids worldwide report includes a survey of 2,000 parents with children under age 6. While the number of children visiting an emergency department for accidental poisonings had declined since the 2010 maximum, the decline has slowed in recent years.

Prescription and over-the-counter medicines cause the most severe poisonings, but vitamins and supplements(补充品)can also cause problems. There are steps families can take to lower the risk for an accidental medicine poisoning.

1.Why are children poisoned according to the text?

A. Some of the medicines at home taste nice

B. There is something poisonous in medicines

C. Kids have easy access to medicines at home

D. Kids are curious to explore the environment

2.What can we learn from the text?

A. Vitamins and supplements can do good to kids

B. The team made a survey of 2,000 kids under age 6

C. 600 parents surveyed could keep medicines properly

D. Kids are usually smart at storing medicines at home

3.What could be the best title for the text?

A. Parents’ Casual Behavior Leads to Kids Poisoned

B. The Number of Kids Poisoned Has Declined Lately

C. Nearly 60,000 Children Are Poisoned by Medicines

D. Kids Are Facing the Risk of Being Poisoned at Home
