Why is increase in livestock production necessary?The world will need to double food production within the next three decades in order to feed a rapidly growing and an increasingly affluent population, which has projected to grow from 7 billion today to 9 billion. A United Nations report says reaching that goal will require major increases in intensive, high-efficiency livestock operations for both meat and dairy production. The report also says that intensive livestock operations can pose serious ecological risks. And that’s why environmental critics are calling instead for reductions in global livestock production, and urging people to consume less, not more, meat in their diets. (30) Feeding today’s population is a challenge for an already-stressed environment. The challenge is how to ensure food without increasing animal numbers and having an impact on fragile lands and our resource bases. More than half of the agricultural land in the world is used to raise and feed livestock. Those farm animals are also responsible for 18 percent of the greenhouse gases released into the atmosphere every year. Experts agree that the next few decades will present a puzzle, how to feed nine billion people without wrecking the planet in the process. Because livestock production is highly efficient. Because more people will become wealthier. Because it has fewer ecological risks. Because it may help double food production.

According to the conversation, an example of “Christmas trimmings“ could be______.M: Hello, Helen! Merry Christmas! W: Merry Christmas, Rob. You always get so excited on Christmas day. M: Come in! Come in! W: Thank you. Wow! M: So, what do you think? W: That’s amazing! So many decorations, and what a beautiful Christmas tree! You must have spent ages doing this. It’s beautiful! M: I like to do Christmas with all the trimmings! W: All the trimmings? I don’t understand. M: All the trimmings—it means all the extra things that traditionally come with something to make it more special. W: I see. Like all these decorations? M: Yes. (1) In my family, we have always had Christmas with all the trimmings, so we have a Christmas tree, decorations, gifts, Christmas songs, silly Christmas games, and most importantly, Christmas lunch. Come this way. W: A turkey for lunch? M: Now that is a roast turkey with all the trimmings! Not only is it a turkey, but (2) we’re eating it with all the things you traditionally eat with Christmas roast turkey: cranberry sauce, roast potatoes, gravy, stuffing, carrots. W: I think I understand what “all the trimmings“ means now. M: It’s an expression usually used with food, especially at Christmas and for the big roast dinners that we like to eat.

According to the passage, what benefit can technology bring to people?Once upon a time, societies were organized around religion, farming, trade or industry. In many parts of the world today this is still true, but something else is becoming more important—the exchange of information, and the technology that we use to do this. Twenty-four-hour news, e-commerce, mobile phones, Global Positioning Systems... all these are making the world smaller and faster. (14) The growth in telecommunications is giving more and more people access to the science that will help their country to develop or to acquire the medical knowledge that can fight disease. But how can everybody in the world share the recent technological advances? (15) Millions of people cannot read these words because they don’t have access to a computer. They don’t understand English either. They don’t even have a telephone. They are more worried about how far they will have to walk today to get clean water or if they can feed themselves and their families. For most people on this planet, information is not a priority. (17)The United Nations is now trying to make the information society a reality for more of the developing world. (16) Ten years from now, the plan is that everybody in the world will have a radio or television and that 50% of the world’s population will have access to the Internet from schools and universities, health centers and hospitals, libraries and museums. This will improve medical care and education, science and agriculture, business opportunities and employment. More useful information to better their life. Greater changes in social organization. Better understanding of mass media. Closer contact with modern devices.

What is the main purpose of the new rules?The Federal Aviation Administration, or FAA, the government agency that regulates civil aviation in the United States, announced new rules this month to combat pilot fatigue. (27) The new guidelines, which will go into effect in two years, call for reducing the number of pilots’ on-duty hours and giving them a 10-hour rest period between shifts, so they can get at least 8 hours of uninterrupted sleep. (28) The new rules apply to only pilots of passenger airlines. FAA determined that including pilots who fly cargo planes—a large segment of the aviation industry—would add too much to the cost of implementing the changes . But the Independent Pilots Association has filed a lawsuit asking the government to set one level of safety for all pilots. To reduce the number of pilots on duty. To prevent pilots from working overtime. To ensure an adequate amount of sleep. To fix the amount of work for each pilot.

I was standing in my kitchen wondering what to have for lunch when my friend Taj called. “Sit down,“ she said. I thought she was going to tell me she had just gotten the haircut from hell. I laughed and said, “ It can’t be that bad. “ But it was. Before the phone call, I had 30 years of retirement saving in a “safe“ fund with a brilliant financial guru(金融大亨). When I put down the phone, my savings were gone. I felt as if I had died and, for some unknown reason, was still breathing. Since Bernie Madoffs arrest on charges of running a $65 million Ponzi scheme, I’ve read many articles about how we investors should have known what was going on. I wish I could say I had reservations about Madoff before “the Call“ , but I did not. On New Year’s Eve, three weeks after we lost our savings, six of us Madoff people gathered at Taj’s house for dinner. As we were sitting around the table, someone asked, “ If you could have your money back right now, but it would mean giving up what you have learned by losing it, would you take the money or would you take what losing the money has given you?“ My husband was still in financial shock. He said, “I just want the money back. “ I wasn’t certain where I stood. I knew that losing our money had cracked me wide open. I’d been walking around like what the Buddhists call a hungry ghost; always focused on the bite that was yet to come, not the one in my mouth. No matter how much I ate or had or experienced, it didn’t satisfy me, because I wasn’t really taking it in, wasn’t absorbing it. Now I was forced to pay attention. Still, I couldn’t honestly say that if someone had offered me the money back, I would turn it down. But the other four all said that what they were seeing about themselves was incalculable, and they didn’t think it would have become apparent without the ground of financial stability being ripped out from underneath them. My friend Michael said, “I’d started to get complacent. It’s as if the muscles of my heart started to atrophy (萎缩). Now they’re awake, alive—and I don’t want to go back. “ These weren’t just empty words. Michael and his wife needed to take in boarders to meet their expenses. Taj was so broke that she was moving into someone’s garage apartment in three weeks. Three friends had declared bankruptcy and weren’t sure where or how they were going to live.

In the 19th century, there used to be a model of how to be a good person. There are all these torrents of passion flowing through you. Your job, as captain of your soul, is to erect dams to keep these passions in check. Your job is to just say no to laziness, lust, greed, drug use and the other sins. These days that model is out of fashion. You usually can’t change your behaviour by simply resolving to do something. Knowing what to do is not the same as being able to do it. Your willpower is not like a dam that can block the torrent of self-indulgence. It’s more like a muscle, which tires easily. Moreover, you’re a social being. If everybody around you is overeating, you’ll probably do so, too. The 19th-century character model was based on an understanding of free will. Today, we know that free will is bounded. People can change their lives, but ordering change is not simple because many things, even within ourselves, are beyond our direct control. Much of our behaviour, for example, is guided by unconscious habits. Researchers at Duke University calculated that more than 40 percent of the actions we take are governed by habit, not actual decisions. Researchers have also come to understand the structure of habits—cue, routine, reward. You can change your own personal habits. If you leave running shorts on the floor at night, that’ll be a cue to go running in the morning. Don’t try to ignore your afternoon snack craving. Every time you feel the cue for a snack, insert another routine. Take a walk. Their research thus implies a different character model, which is supposed to manipulate the neural(神经系统) networks inside. To be an effective person, under this model, you are supposed to coolly examine your own unconscious habits, and the habits of those under your care. You are supposed to devise strategies to alter the cues and routines. Every relationship becomes slightly manipulative, including your relationship with yourself. You’re trying to arouse certain responses by implanting certain cues. This is a bit disturbing, because the important habitual neural networks are not formed by mere routine, nor can they be reversed by clever cues. They are burned in by emotion and strengthened by strong yearnings, like the yearnings for admiration and righteousness. If you think you can change your life in a clever way, the way an advertiser can get you to buy an air freshener, you’re probably wrong. As the Victorians understood, if you want to change your life, don’t just look for a clever cue. Commit to some larger global belief.
