After lunch, while the other girls were sunbathing, Pat and I returned to the water. Soon cramps spread from my stomach to my legs. Immobilized by pain and fear, I yelled for help. My friend thought I was joking: so she ignored me. However, Sister Theresa came to my rescue when she noticed my plight. She pulled me out of the water and administered resuscitation. When regaining consciousness, I realized how close I had come to death. My experience with near death reminds me every day how close we all are to death in our daily lives.
在这个段落里，作者用了after lunch; while...; soon; when...等时间连接语按时间的先后顺序记叙了一件发生在午饭后的事。
There are four separate stages in making bread. The first stage begins by mixing yeast with warm water. This mixture is then added to half the amount of flour. The resultant batter mixture is then left for an hour. At the next stage the rest of the flour is added to the risen batter mixture, along with salt and oil. The main step in the second stage is a thorough kneading of the dough, after which it is left to rise. The third stage involves shaping the dough into loaves; the shaped loaves are then put into bread tins and left to ‘prove’ (rise). In the final stage the bread is cooked in a hot oven. The whole process of bread making finishes when the bread is taken from the oven and left to cool on wire racks.

The room was disgusting. By the far window was a trash can piled high with crumpled papers. In the middle of the room was a gaudy, round size bed littered with rotting fruit peels. The path between the bed and the doorway, where I was standing, was choked off by heaps of dirty clothes and old newspapers.

Social activities benefit us in many ways. To begin with, these activities can widen our knowledge, because we can learn what we can’t from our books. Second, these activities can serve as a bridge between theory and practice, because we can learn how to put our book knowledge into practice. Lastly, these activities can enrich our experience, in that we can get to know the society well so that we can adapt to it easily when we graduate.
本段的第一句是段落主题句，in many ways在这里为下面的列举作好了铺垫。作者用了to begin with, second和lastly作为连接语，条理清楚地列举了社会活动有益的三个方面。
Many old buildings in cities are still being found useful. In several cities, old buildings that were no longer being used have been converted to a variety of useful structures. For example, one school building was changed into ninety nine rental units for elderly and low income residents. In Baltimore, Maryland, six schools were converted into 132 units with the help of a four million dollar city bond financing arrangement. “School House 77” in Boston utilizes three recycled elementary schools and an abandoned instrument factory. All these examples show how cities are using unneeded schools, police stations, libraries, and boarded up factories that are structurally sound and even architecturally interesting buildings.
It is very difficult to evaluate another person’s performance objectively. For example, Linda recently wrote irresponsible remarks about her instructor because she was failing the course. Her friend Jack wrote a marvelous description of the same instructor because he was receiving an A in the course. Both Linda and Jack were not fairly evaluating the instructor. They were influenced by the grades they were earning and were biased in their judgment.
Why do so many graduates gravitate into business instead of into teaching? Part of the reason is the ever widening pay gap between these two professions. A secretary, an office clerk or a bank employee can earn monthly income as high as RMB 2，000, and when one is promoted to the position of a business executive or manager, the salary is even higher. But a college graduate with a master’s degree can only get a salary of RMB 1，000 per month for his teaching job. No wonder, college graduates are attracted into more lucrative（赚钱的，有利润的） fields.
There are striking similarities between two of the most popular U.S. presidents, Abraham Lincoln and John F. Kennedy. Both men had their elections legally challenged. Lincoln and Kennedy are both remembered for their sense of humor, as well as for their interest in civil rights. Lincoln’s secretary was Mrs. Kennedy; Kennedy’s secretary was Mrs. Lincoln. Neither man took the advice of his secretary not to make a public appearance on the da y on which he was assassinated. Lincoln and Kennedy were both killed on Friday in the presence of their wives. And finally, the same caisson（弹药车） carried the bodies of both men in their funeral processions.
Astronomers have been able to classify stars according to color. They have discovered that stars with different colors have different sizes, and their surface temperatures are also different. The larger a star is, the higher surface temperature it has. Stars are generally divided into five kinds: blue, white, yellow, orange and red. Blue stars are the largest ones, with a diameter of 16,000,000 kilometers. Their surface temperature is also the hottest, as high as 25,000 degrees centigrade. White stars come next, whose diameter is 2,700,000 kilometers and whose surface temperature is 11,000 degrees centigrade. Then there are yellow stars, 1,600,000 in diameter and 6,000 degrees centigrade in surface temperature. Orange stars are still smaller. They have a diameter of 1,000,000 kilometers and a surface temperature of 5,000 degrees centigrade. The smallest kind of stars appears red in color. Their diameter is only one twentieth of that of blue stars, that is, 800,000 kilometers, and their surface temperature is only 3,000 degrees centigrade.
There are two kinds of sports: “amateur” and “professional”. Amateur athletes do not receive money for competing in sports. Olympic athletes, for example, are amateurs. They do not receive money. Professional athletes, on the other hand, do earn money. Some professional athletes earn a million dollars or more a year. They need this money to support themselves and they can save some for their future.
本段的主题句也在段落开头，指出运动有两种形式：业余的和专业的。然后，作者采用分类法发展段落，分门别类地对业余类（amateur athletes）和专业类（professional athletes）进行解释说明，使段落主题更明确地展示在读者面前，段落层次清楚，中心思想统一明了。
Examinations fall into three kinds. One is the machine scored “objective” type. In an objective test, the students answer questions by deciding on best choice among a number of alternatives given. Another is the “completion” type. This kind of examination requires the students to add a word or phrase to complete a sentence. And the third type is the essay examination, in which the students are asked to wri te a composition on a given topic. All these kinds of examinations are designed to reveal what a student may have learned in any particular course.
本段采用分类法来展开段落。主题句在段落开头，指出“考试可分三种类型”。然后，作者运用One is the machine scored “objective type”, Another is the “completion type”,” And the third type is the essay examination” 来清楚地将考试分类阐述，段落脉络一目了然，层次十分分明。
Love is a very general term. It refers to a strong feeling of fondness for another person. It can happen between people of the opposite sex or between members of a family. No matter where it happens, love can always bring happiness to people.

Poetry is a branch of literature which explores ideas, emotions, and experiences in a distinctive form and style. Poetry, sometimes called “verse”, depends greatly on the natural rhythms and sounds of language for its special effects. Poetry, even more than prose (all other writings), depends on precise and suggestive wording. In other words, a poem says much in little space. Poetry differs from prose in obvious ways, also. Most often the first word of every line begins with a capital letter, even in the middle of a sentence. Poems sometimes contain rhyme, and often they have a particular rhythm, like music.
Homes that are improperly insulated may cause problems for their habitants. First of all, it will cost more to heat such a house than one that is well insulated. Second, it will waste energy. Third, it will make the house uncomfortable to live in because drafts or cold air is able penetrate the poorly insulated walls. Also, the poorly insulated walls could cause the inhabitants to have more colds, a health problem that results in higher expenses for doctors and medicine.
本段第一句是主题句，指出导致problem for their habitants 的是homes that are improperly insulated。然后集中笔墨阐明结果，在这里即problems。
So why do manufacturers keep on designing and producing VCRs that are awkward to use if the problems are so obvious? First, the problems we notice are not obvious to technically minded designers with years of experience and trained to understand how appliances work. Secondly, designers tend to add one or two features at a time to each model , whereas you and I face all of a machine’s features at once. Thirdly, although finding problems in a finished product is easy, it is too late by then to do anything about the design. Finally, if manufacturers can get away with selling products that are difficult to use, it is not worth the effort of any one of them to make improvements.
Balloons have been used for sports for about 100 years. There are two kinds of sports balloons: gas and hot fire. Hot balloons are preferred by most balloonists in the United States because of their safety. They are also cheaper, and easier to manage than gas balloons. Despite the ease of operation on a balloon, pilots must watch the weather carefully. Sport balloon flights are best early in the morning or late in the afternoon, when the wine is light. Over the years balloonists have tried unsuccessfully to cross the Atlantic Ocean. It wasn’t until 1978 that three American balloonists succeeded. It took them just six days to make their trip from their home in the United States to Paris, France. Their voyage captured the imagination of the whole world.
