Here are some major reasons for such a decision.1.The health reasonMedical studies prove that a vegetarian diet is easier to digest, provides a wider range of nutrients(营养) and has fewer burdens on the body. Vegetarians are less influenced by all the major diseases, and thus live longer, healthier, more productive lives. They have fewer physical plaints, less frequent visits to the doctor, and smaller medical bills.In a word, they are in the most natural conditions of life.2. __________________Planet earth is suffering. In large measure, the great loss of species, destruction of ancient rainforests to create lands where animals can feed on grass, loss of top soils, and the increase of water impurities(杂质) and air pollution have a mon cause which is the single fact of meat in the human diet. No single decision that we can make as individuals or as a race can have such a dramatic effect on the improvement of our planetary ecology(生态) as the decision not to eat meat. Many seeking to save the planet for future generations have made this decision for this reason and this reason alone.3.The economic reasonThe simple fact is that to produce 1 kilogram of meat, it requires over 16 kilograms of grain and much more water. Millions of animals are bred for meat production. If they were not bred, the vegetation would be used to feed people. And more people in hunger would have their food.56. Vegetarians prefer to live on vegetables for the reasons EXCEPT that _______.A. vegetables are easier to digestB. they provide more kinds of nutrientsC. vegetables are cleaner than meatD. the body will have fewer burdens57. Which of the following statements is TRUE according to this passageA. Vegetarians will spend no money on medical care.B. Vegetarians have more children in their life.C. Vegetarians are usually thinner.D. Vegetarians can save the planet for future generations.58. What might be the proper title for the second partA. The ecological reason.B. The pollutant reason.C. The plant reason.D. The generation reason.59. Which of the following might the writer agreeA. Fewer animals should be bred to produce more grain for people.B. Animals shouldn’t be raised.C. We should save animals.D. Living on vegetables can solve the problem of hunger.60. If people live on vegetables, which of the following may NOT be affected by itA. Species of animals.B. Air quality.C. People’s health.D. Grain quality( B )Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品 ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.Soon afterwards, Woolworth opened his own store., selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placedan order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”61. Frank took a short business course in order to ____________.A. earn more money for his familyB. learn something from a salesmanC. get away from the farmD. get enough to eat.62. Frank sold the odds and ends quickly because _____________.A. he knew how to get people to buy his goods.B. he cut down the price by halfC. he had put the goods on a table in a very nice way.D. the sign he put on the table was well designed.63. The price of the knives was cut down by half because ______________.A. the factory workers worked 24 hours a day.B. knives were ordered in large quantities directly from the factory.C. the knives were made in Germany, where labour (劳动力) was cheap.D. the knives were produced in one factory.64. _____________ make Woolworth a world-famous man.A. His business skills and his wealth.B. The low price of the goods he sold.C. His trip to Germany and his huge order of knives.D. His natural skill for showing things.65. The belief that : “ The customer is always right” suggests that_______________.A. whenever there is a quarrel between the customer and shopassistant, the customers are always right.B. If you want to succeed, the rule is the only way.C. stores must always follow the customer’s orders if they wantto make more money.D. stores should do their best to meet the customer’s needs if theywant to be successful.( C )About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.Some insects have favorite colors. Mosquitoes prefer blue to yellow.A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.66. The passage is mainly about _____________.A. color and its surprising effects.B. women being luckier than menC. danger caused by color blindnessD. color blindness67. According to the passage, with the help of the “cones”, we can_______________.A. tell different shapesB. see in a weak lightC. kill mosquitoesD. tell orange from yellow68. Why do some people say it is safer to be driven by womenA. Women are more careful.B. There are fewer color-blind womenC. Women are fonder of driving than men.D. Women are weaker but quicker in thinking.69. Which of the statements about the color- blind is trueA. Not all of them have the same problem in recognizing color.B. None of them can see deep red.C. None of them can tell the difference between blue and green.D. All of them see everything in shades of green.70. We can attract and kill mosquitoes by using a _____________.A. red lightB. yellow lightC. blue lightD. green light( D )Rome had the Forum (论坛). London has Speaker’s Corner. Now always-on-the-go New Yorkers have Liz and Bill.Liz and Bill, two college graduates in their early 20s, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street ers. And just talk.Using a 2-foot-tall sign that says, “ Talk to Me,” they attract conversationalists, who one evening included a mental patient, and men in business suits.They don’t collect money. They don’t push religion (宗教). So what’s the point“ To see what happens,” said Liz. “ We simply enjoy life with open talk.”Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return.“ It started as a crazy idea.” Liz said. “ We were so curious about all the strangers walking by with their life stories. People will talk to us about anything: their job, their clothes, their childhood experiences, anything.”Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went.Marcia had led her husband to a serious disease. “That was very heavy on my mind.” Marcia said. “ To be able to talk about it to total strangers was very good,” she explained.To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people appeared, as well as some television cameramen and reporters.They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something the two say they’ll consider before making a decision. 71. What did Liz and Bill determined to do after the attack on September 11, 2001A. Telling stories to strangers.B. Setting up street signs.C. Talking with peopleD. Organizing a speaker’s party.72.

第一单元生活与消费1.1揭开货币的神秘面纱[客观题]1、商品的含义及其基本属性★商品:用于交换的劳动产品。
基本属性:使用价值和价值。
⑴使用价值:能够满足人们某种需要的属性。
(商品的自然属性,具有多样性,所有物品都具有。
⑵价值:凝结在商品中的无差别的人类劳动。
(商品的社会属性,只有商品才具有,只有通过交换才能实现。
)2、货币的含义、本质及职能★⑴货币:是从商品世界中分离出来固定地充当一般等价物的商品。
货币的本质是一般等价物。
⑵一般等价物:是大家普遍乐意接受的商品,它表现其他一切商品的价值,充当商品交换的媒介。
⑶货币的基本职能:价值尺度、流通手段。
①价值尺度:货币所具有的表现和衡量其他一切商品价值大小的职能(注:价值尺度不需要现实的货币,只是观念的货币)。
②流通手段:货币充当商品交换媒介的职能,叫作流通手段。
(注:流通手段需要现实的货币;是一手交钱,一手交货,买卖同时进行,没有时间差)。
货币的其他职能:①贮藏手段(被当作社会财富的一般代表保存起来,必须是“足值的金银”);②支付手段(在赊帐买卖中,货币被用来偿还债务,支付地租、利息、税款、工资等;买卖不同时进行,有时间差);③世界货币(作为社会财富的代表在国与国之间转移。
一些国家的纸币也会具有世界货币的职能)。
3、纸币(货币)的供应(发行)规律★货币供应规律:货币的供应量必须以流通中所需要的货币量为限度。
(货币的供应量=待售商品数量×商品价格水平/货币流通速度(次数)=商品价格总额/货币流通速度)[易错易混点]1.人们选择商品是关注商品的有用性。
(错误)(关注性价比,即使用价值和价值的统一体)2.货币天生是金银,但金银天生不是货币。
作为一般等价物,金银和贝壳的本质是相同的3.纸币的发行、面值或面额由国家决定,纸币的购买力由市场决定。
