5. Passage ThirtyThe Chinese have used a method called acupuncture (针灸)to help perform operations for about 4, 000 years without putting the patient to sleep.This involves inserting flexible needles into certain parts of the body.The needles are available in a number of stores in China and everyone may buy them.To learn how to use needles takes about one month of training.But to be skillful requires greater time.The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful.This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed.In the past, a particular operation might require 25 or more needles placed in various parts of the body.But now this operation requires only 3 or 4 needles.Today, the Chinese doctors are trying to learn more about acupuncture.They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, would prevent the pain in the area of the mouth.A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep.It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation whereas the chemical may make the patient sick for a few hours or a day.Which is implied but NOT stated in the passage?

4. Passage Thirty-OneAdam Smith was the first person to see the importance of the division of labor.He gave us an example of the process by which pins were made in England.“One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, and a fifth gives it a head.Just to make the head requires two or three different operations.The work of making pins is divided into about eighteen different operations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them.”Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4,800 pins a worker.But if all of them had worked separately and independently without division of labor, they certainly could not have made twenty pins in a day and not even one.There can be no doubt that division of labor is an efficient way of organizing work.Fewer people can make more pins.Adam Smith saw this, but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still.But division of labor adds nothing new, it only enables people to produce more of what they already have.According to the writer, Adam Smith’s mistake was in believing that the division of labor ().

1. Passage TenNowadays, children heavily cling to digital devices such as computers and smart phones.Some spend up to six hours a day on their digital devices.They can be playing games online with people elsewhere, updating their status on social media, texting friends, or looking for the latest apps to download to their computers or smart phones.This worried Martin Strott.He is the headmaster of the Old Hall School in Wellington, England.He was so concerned that he challenged his students to take part in a week of (“digital detox”), a program to reduce their reliance on digital devices.Mr.Strott told the local newspaper, the Shropshire Star, that too much screen time would affect the development of their social skills.At another interview with a magazine, he mentioned that this over-reliance on digital devices “takes away family time and reduces their chances of face-to-face communication”.The parents are happy with the program.But what about the children? Nine-year-old Fred usually spends around two hours on his digital devices at home after school and around 12 hours on weekends.For him, the digital detox experience was “really hard”.He said that he had been engaged in many interesting outdoor activities organized by the headmaster, but still missed his phone and online games.The idea of keeping children away from their digital devices for a while to prevent too much dependence on them is not particularly new.There have been similar practices in the United States.But are they effective in the long run? According to Mr.Strott, even if kids go back to their digital devices, the hope is that at least they will think about how they will use their time.According to Paragraph 1, what would children do when they cling to their digital devices?
