food security

As the old proverb goes “bread is the staff to life”. Food security plays an extremly important role in our daily life. But as the competiton between food manufatuerers is becoming so violently, the quality and quantity of food tend to be much worse and worse. So food security has become a serious problem which has aroused many concerns from the whole society.

As far as I’m concerned, I think there several ways to improve the safety of food. On the one hand, I think there’re must be some defects in the governmental functional department, and that is the reason why we can buy the bad quality food in the market. So government should strenghten the degree of the food’s supervision. The rigorous supervision system must be covered in the every process of food’s producing. I think that can do a lot of help to the level of food security.

On the other hand, foods manufactuerers always concentrate on exaggerate the profits and ignore the food security. So I think it is necessary to improve the businessmen’s social morality and accountability. Only in this way can let the producers take ensure food security as their own course and do something good to it.

As for consumers, we also should be attentive to discern the quality of food. We should pay attention to the date when the food produced, the place where the food come from and how long the food can be stored. Only in this way can protect us. And also I think, if every one can take action now to improve the food security, we wouldn’t have to worry about food security any more.

Chapter 9 Lecture: Public Education: Philosophy and Funding Most young people in the United States, like most young people around the world, attend public school. Indeed, young people in the U.S. have to attend school because education is compulsory, in most states to the age of sixteen or until the students reach ninth grade. A small percentage of American youth attend private schools, wither religious or secular schools, but the vast majority attend public schools. One distinguishing feature of U.S. public education that surprises many foreigners is that although there are some standardized examinations, there is no nationwide curriculum set by the government ministry of education determines the curriculum that all students study and the examinations that all the students take at a set time. Of course, U.S. students follow a curriculum, and they take examinations as all students do. Although the federal government does influence public education by providing funds to schools for special programs such as education for the handicapped and for bilingual education, the federal government does not determine the curriculum or the examinations. Today I’d like to talk about the three levels of control within each state and then spend some time discussing where the money for education comes from and three issues related to funding. Control of education in the United States is mainly exercised locally at three levels. Let’s begin with the state department of education. The department of education of each of the fifty states has two basic functions. First, each state department of education sets basic curriculum requirements for all the schools in its state. For example, a high school might require four years of English, three years of math, two years of social science, and so forth. The state also sets the number of credits a student must complete in order to graduate from a high school. This total number of credits includes both required courses and electives. So much for the state part in education. The second level of control is the school district. The number of school districts a state has depends on the size of its population and the size of the state. A large metropolitan area would have several school districts. A smaller community might have only one district. Each school district is run by a school board that is elected by the citizens of the district. The school district is responsible for the specific content of courses taught in its schools. In other words, the school district determines what the students will study in each of their, let’s say, four years of high school English. The school district also decides what electives will be available for students. Besides determining course content, the school district is responsible for the operation of the schools in its district, for example, the hiring if teachers and administrators. The third level of control is the individual school itself, where teachers have primary responsibility for deciding how to teach the content of each course and for preparing and giving examinations to the students. Local control of schools may seem very strange to some of you, but it will seem less strange if you consider how public schools in the United States are funded- that is, where money to run the schools comes from. Only about 7 percent of the money comes from the federal government. The rest of the money comes from state and local taxes. The percentages supplied by the state and by the local districts fluctuate over tome and from state to state. Currently appropriately 49 percentage of school funding comes from the states and about 44 percent comes from the local communities, that is, the school districts. Finally, I’d like to discuss three issues related to the funding of schools that have been receiving a lot of attention recently in the United States. The first issue deals with the

Book 2 Chapter 1 The Population Today we’re going to talk about population in the United States. According to the most recent government census, the population is 281,421,906 people. Now this represents an increase of almost 33 million people since the 1990 census. A population of over 281 million makes the United States the third most populous country in the whole world. As you probably know, the People’s Republic of China is the most populous country in the world. But do you know which is the second most populous? Well, if you thought India, you were right. The fourth, fifth, and sixth most populous countries are Indonesia, Brazil, and Pakistan. Now let’s get back to the United States. Let’s look at the total U. S. population figure of 281 million in three different ways. The first way is by race and origin; the second is by geographical distribution, or by where people live; and the third way is by the age and sex of the population. First of all, let’s take a look at the population by race and origin. The latest U. S. census reports that percent of the population is white, whereas percent is black. Three percent are of Asian origin, and 1 percent is Native American. percent of the population is a mixture of two or more races, and percent report themselves as “of some other race”. Let’s make sure your figures are right: OK, white, percent; black, percent; Asian, 3 percent; Native American, 1 percent; a mixture of two or more races, percent; and of some other race, percent. Hispanics, whose origins lie in Spanish-speaking countries, comprise whites, blacks, and Native Americans, so they are already included in the above figures. It is important to note that Hispanics make up percent of the present U.S. population, however. Finally, the census tells us that 31 million people in the United States were born in another country. Of the 31 million foreign born, the largest part, percent are from Mexico. The next largest group, from the Philippines, number percent. Another way of looking at the population is by geographical distribution. Do you have any idea which states are the five most populous in the United States? Well, I’ll help you out there. The five most populous states, with population figures, are California, with almost 34 million; New York, with 21 million; Texas, with 19 million; and Florida, with 16 million; and Illinois with million people. Did you get all those figures down? Well, if not, I’ll give you a chance later to check your figures. Well, then, let’s move on. All told, over half, or some 58 percent of the population, lives in

非生命名词做主语，是英语中非常常见的句式，对这类结构的翻译不可拘泥于英语的句式，不然，译文会违背汉语的表达原则，显得不伦不类。对这类结构的翻译，一般是将英语中的主语（非生命名词）译成汉语中的状语或是宾语。例：His absence puts off the meeting. 因为他缺席，会议延期。 4．Covering 273 ha., the main structure of the Temple of Heaven include...... 占地273公顷，天坛的主体结构包括…… （1）现在分词短语做状语的英语句子翻译成汉语时，要根据分词短语所做的状语的不同类别，加上适当的关联词，如表示原因的，表示让步的，表示条件的等等。例：1.Weather permitting, we will start tommorrow. (如果)天气允许，我们明天开始。 2.Being late, I was punished. （因为）迟到，我受到了惩罚。（2）“cover”一词词义较为广泛，常见的用法有“占用”、“覆盖”和“含盖”等意思。 The money which our company gives you will cover your traveling expense. 我们公司给你的钱也将含盖你的差旅费。 Unit 2 Sports 1.The founding of the People's Republic of China in 1949 brought about

Today we’re going to talk about population in the United States. According to the most recent government census, the population is 281,421,906 people. Now this represents an increase of almost 33 million people since the 1990 census. A population of over 281 million makes the United States the third most populous country in the whole world. As you probably know, the People’s Republic of China is the most populous country in the world. But do you know which is the second mo st populous? Well, if you thought India, you were right. The fourth, fifth, and sixth most populous countries are Indonesia, Brazil, and Pakistan. Now let’s get back to the United States. Let’s look at the total U. S. population figure of 281 million in three different ways. The first way is by race and origin; the second is by geographical distribution, or by where people live; and the third way is by the age and sex of the population. First of all, let’s take a look at the population by race and origin. T he latest U. S. census reports that 75.1 percent of the population is white, whereas 12.3 percent is black. Three percent are of Asian origin, and 1 percent is Native American. 2.4 percent of the population is a mixture of two or more races, and 5.5 percen t report themselves as “of some other race”. Let’s make sure your figures are right: OK, white, 75.1 percent; black, 12.3 percent; Asian, 3 percent; Native American, 1 percent; a mixture of two or more races, 2.4 percent; and of some other race, 5.5 percent. Hispanics, whose origins lie in Spanish-speaking countries, comprise whites, blacks, and Native Americans, so they are already included in the above figures. It is important to note that Hispanics make up 12.5 percent of the present U.S. population, however. Finally, the census tells us that 31 million people in the United States were born in another country. Of the 31 million foreign born, the largest part, 27.6 percent are from Mexico. The next largest group, from the Philippines, number 4.3 percent. Another way of looking at the population is by geographical distribution. Do you have any idea which states are the five most populous in the United States? Well, I’ll help you out there. The five most populous states, with population figures, ar e California, with almost 34 million; New York, with 21 million; Texas, with 19 million; and Florida, with 16 million; and Illinois with 12.5 million people. Did you get all those figures down? Well, if not, I’ll give you a chance later to check yo ur figures. Well, t hen, let’s move on. All told, over half, or some 58 percent of the population, lives in the South and in the West of the United States. This figure, 58 percent, is surprising to many people. It is surprising because the East is more densely populated. Nevertheless, there are more people all together in the South and West. To understand this seeming contradiction, one need only consider the relatively larger size of many southern and western states, so although there are more people, they are distributed over a larger area. To finish up this section on geographical distribution, consider that more than three-quarters of the people live in metropolitan areas like Los Angeles, New York, Chicago, and Houston. That means that only 20 percent, or 2 out of 10 people, live in rural areas. An interesting side note is that some 3,800,000 U.S. citizens live abroad, that is, in foreign countries. Before we finish today, I want to discuss the distribution of the U.S. population in terms of age and sex. Just for interest, would you say there are more men or more women in the United States? Well, according to the 2000 census, there are more women. In fact, there are more than five million more women than men in the U.S. population. If we consider that more males than females are born each year, how can this difference be explained? Well, for a variety of complicated reasons that we can’t go into here, there is a progressively higher death rate for males as they get older. This is seen in 2003 life expectancy figures: the life expectancy for women is 80.4 years whereas for men it is only 74.5 years. I don’t know how these life expectancy figures compare to those in your countries, but statistically women generally live longer than men worldwide. Now, to finish up, let’s look at the average age of the whole population. Overall, the average age of the population is increasing: from 33.1 years in 1990 to 35.3 years in 2000. The average age has been slowly, but steadily, increasing over the past several decades. This trend toward a higher average age can be explained by a decreasing birth rate and an increasing life expectancy for the population as a whole. Well, I’d like to investigate these two subjects further, but I see our time is up, so we’ll have to call it quits for today. Yo u may want to pursue the topic of the aging U.S. population further, so there are some suggestions at the end of the lesson to help you do so. Thank you. Chapter Two Immigration: Past and Present The act of immigrating, or coming to a new country to live, is certainly nothing new. Throughout history, people have immigrated, or moved to new countries, for many different reasons. Sometimes these reasons were economic or political.
