    Like most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving away makes life much more exciting. You need not worry if you lack money.

    This is how I experimented with giving away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form.

    One Sunday morning, the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard(无意中听到) our conversation. “Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home?” I said yes. “Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing but complaints.”

(1)、From the passage, we understand that ________.

A、the author did not understand the importance of giving until he was in late thirties B、the author was like most people who were mostly receivers rather than givers C、the author received the same education as most people during his childhood D、the author liked most people as they looked upon life as a process of getting

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

         While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

         Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

          The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    In cities with rent control, the city government sets the maximum rent that a landlord (房东) can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.

    Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

    Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

    Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

    Five or six years ago, I attended a lecture on the science of attention. A professor who conducts research over in the medical school was talking about attention blindness, the basic feature of the human brain that, when we concentrate on one task, causes us to miss just about everything else. Because we can't see what we can't see, our lecturer was determined to catch us in the act. He had us watch a video of six people tossing (投掷) basketballs back and forth, three in white shirts and three in black, and our task was to keep track only of the tosses among the people in white. The tape rolled, and everyone began counting.

    Everyone except me. I'm dyslexic (患阅读困难症的), and the moment I saw that tape with the confusing basketball tossers, I knew I wouldn't be able to keep track of their movements, so I let my mind wander. I became curious, though, when about 30 seconds into the tape, a gorilla (大猩猩) walked in among the players. She (we later learned a female student was in the gorilla suit) stared at the camera, beat her chest with her fist, and then went away while they continued passing the balls.

    When the tape stopped, the professor asked how many people had counted at least a dozen basketball tosses. Hands went up all over. He then asked who had counted 13, 14, and congratulated those who'd scored the perfect 15. Then he asked, “And who saw the gorilla?”

    I raised my hand and was surprised to discover I was the only person at my table and one of only three or four in the large room to do so. He'd set us up, trapping us in our own attention blindness. Yes, there had been a trick, but he wasn't the one who had played it on us. By concentrating so hard on counting, we had managed to miss the gorilla in the midst.

    Attention blindness is the fundamental organizing principle of the brain, and I believe that it presents us with a great opportunity. My take is different from that of many neuroscientists: Where they see the shortcomings of the individual, I sense an opportunity for cooperation. Fortunately, given the interactive (互动的) nature of most of our lives in the digital age, we have the tools to control our different forms of attention and take advantage of them.

    It's not easy to admit that everything we've learned about how to pay attention means that we've been missing everything else. It's not easy for us logical, intelligent, confident types to admit that the very key to our success — our ability to discover a problem and solve it, an achievement obtained in all those years in school and beyond — may be exactly what limits us. No one ever told us that our way of seeing left out everything else.

    Smart Cameras to Help You Take Better Photos

    Google Clips

    One of the latest to launch (发布) is Google Clips. It is designed to be put somewhere in a room to take pictures by itself. It can also be attached to an object or a person's clothing.

    Google says machine learning helps the camera choose the best times and situations for taking pictures and videos. Interested buyers can join a waiting list to be informed when it is on the market.

    GoPro Hero

    GoPro also uses machine learning to power its QuikStories characteristic. This tool takes existing photos and videos and automatically (自动地) creates a finished video piece, complete with music and effects.

    Snap Spectacles

    Messaging app Snapchat sells a pair of sunglasses with a built-in camera that can record short videos with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “catch the moment, without taking you out of it.”

    The glasses can record short video clips that can be shared with Snapchat users. Snap Inc. has started selling its Spectacles sunglasses online in the United States.

    Apple iPhone X

    Apple's new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous ones that used a fingerprint to unlock the phone.

    Apple says the system works by projecting more than 30,000 dots on the face to create a kind of map. Apple says its facial recognition is even secure enough to allow payments through its Apple Pay service.

    Food production does great harm to our environment. There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants. Some procedures require the consumption of large amounts of fossil fuels, such as the transportation and storage of food products. Other factors that cause great damage to our environment include the overuse of fresh water.

    The production of beef is more damaging to the environment than that of any other food we consume. Raising large numbers of cattle requires the production of large amounts of food for the animals. It's estimated that producing one pound of beef requires seven pounds of feed.

    Land use is also a problem. If the cattle are free-range cattle, large areas of land are required for them to live on. This has led to disastrous forest cutting and the loss of rare plants and animal species, particularly in tropical rain forests in Central and South America.

    Another problem specific to beef production is methane emissions (甲烷排放). Although many people are aware of the damaging effects of carbon dioxide, they don't realize methane's global warming potential is 25 times worse, making it a more dire problem.

    Unfortunately, beef consumption is growing rapidly. This is the result of simple supply and demand factors. Specifically, there are two main causes of demand that are encouraging the production of more supply. First, the increase in the world population means there are more people to consume meat. The second factor is socioeconomic advancement. As citizens in developing nations become financially stable, they can afford to buy more meat.

    Therefore, one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.
