Americans today have different eating habits than in the past. There is a wide selection of food available. They have a broader knowledge of nutrition, so they buy more fresh fruit and vegetables than ever before. At the same time, Americans purchase increasing quantities of sweets, snacks and sodas.
点击查看答案
Statistics show that the way people live determines the way they eat. American life styles have changed. They now include growing numbers of people who live alone, single parents and children, and double income families. These changing life styles are responsible for the increasing number of people who must rush meals or sometimes skip them altogether. Many Americans have less time than ever before to spend, and almost all American homes now have microwave ovens. Moreover, Americans eat out nearly four times a week on the average.
It is easy to study the amounts and kinds of food that people consume. The United States Department of Agriculture (USDA) and the food industry growers, processors, marketers and restaurateurs compile sales statistics and keep accurate records. This information not only tells us about what people are eating, but in, fluences them on what to eat. Red meat, which used to be the most popular choice for dinner, is no longer an American favorite. Instead, chickens, turkey, and fish have become more popular. Sales of these foods have greatly increased in recent years. This is probably a result of the awareness of the dangers of eating food which contains high levels of cholesterol, or animal fat. Doctors believe that cholesterol is a threat to human health.
According to a recent survey, Americans also change their eating patterns to meet the needs of different situations. They have certain ideas about which foods will increase their athletic ability, help them lose weight, make them alert for business meetings, or put them in the vegetables, which supply them with carbon hydrates, to give them strength for physical activity, such as sports. Adults choose foods rich in fiber, such as bread and cereal for breakfast, and salads for lunch to prepare them for business appointments. For romantic dinners, however, Americans choose shrimp and lobster. While many of these ideas are based on nutritional facts, some are not. Americans' awareness of nutrition, along with their changing tastes and needs, leads them to consume a wide variety of foods — foods for health, for fun, and simply for good taste.
Americans have different eating habits today chiefly because ______.
A．there are more shops and restaurants in the country
B．a great number of families have microwave ovens
C．their life styles are different now
D．they are busier with their work than before

We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.
点击查看答案
The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database.
In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome(染色体)),” explains Ugo A．Perego, a member of the BYU Molecular Genealogy research team.
People in a large area may possess the same DNA thread because______.
A．DNA is characteristic of a region
B．they are beyond doubt of common ancestry
C．DNA strand has the ability to identify individuals
D．their unique identification can be provided via DNA
第10题
The aim of the teacher is to get his pupils as quickly as possible over the period in which each printed symbol is looked at for its shape, and arrive at the stage when the pupil looks at words and phrases, for their meaning, almost without noticing the shapes of these separate letters.
点击查看答案
When a good reader is at work, he does not look at letters, nor even at words, one by one, however quickly; he takes in the meaning of two, three, or four words at a time, in a single moment. Watch carefully the eyes of a person who is reading, and it will be seen that they do not travel smoothly along the lines of print, but they move by jumps separated by very short stops. The eyes of a very good reader move quickly, taking long jumps and making very short halts (停顿); the eyes of a poor reader move more slowly, taking only short jumps and stopping longer at each halt. Some- times, when he meets a difficulty, he even goes backwards to see again what has already been looked at once.
The teacher’s task is therefore clear: it is to train his pupils to take in several words at a glance (one "eye jump" ) and remove the necessity for going backwards to read something a second time.
This shows at once that letter-by-letter, or syllable-by-syllable (音节), or word-by-word reading, with the finger pointing to the word, carefully fixing each one in turn, is wrong, It is wrong because such a method ties the pupil’s eye down to a very short jump. Moreover, a very short jump is too short to provide any meaning or sense; and it will be found that having struggled with three or four words separately, the pupil has to look at them again, all together and in one group, in order to get the meaning of the whole phrase.
Which of the following is closest in meaning to the first paragraph?
A．Pupils should be trained to reach quickly the stage of reading without having to concentrate on the separate symbols.
B．Pupils should look at each printed symbol for its meaning as well as for its shape.
C．Teachers should help their pupils avoid looking at the shape of the printed symbols.
D．Teachers should tell their pupils the different stages of their study.
