单选题 Romeo and Juliet was probably written in 1595, when Shakespeare was a young, successful playwright. He had already written comedies and history plays, but had not yet developed his skill at tragedy. The power of fate is strong in Shakespeare's play. Chance and evil eventually join to bring tragedy. Chance involves Romeo in a murder, chance prevents a message from reaching Romeo in 6me, chance brings about deadly meeting in a cemetery. Many Elizabethans were followers of astrology (星相术) and believed that the stars could control events. Thus, Romeo and Juliet are referred to as 'star-crossed lovers' whose stars doomed (命中注定) them to disaster. Elizabethans also had a concept of fate in the person of Dame Fortune (命运女神). By spinning her wheel, she could raise the state of a beggar or lower that of a king. One of the fascinations of Shakespeare is the way in which he put these ideas into the play. One of the most difficult things to decide about this play is the question of responsibility. Did irresistible fate bring tragedy to Romeo and Juliet, or were they themselves to blame? The fact that this question is not resolved by the author also helps to make Shakespeare's Romeo and Juliet a fascinating work.

单选题 There are many commonly held beliefs about eyeglasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have the wrong glasses. We have all heard some of the common myths about how eyesight get bad. Most people believe that reading in dim light causes poor eyesight, but that is unique. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bet, and watching too much television. But although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from on person to another. There are close to on million verve fibers that connect the eyeball to brain, and as if yet it is impossible to attach them all in a new person. Only certain parts of the eye—the cornea and the retina—can be replaced. But if we keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible!

单选题 We first think of the traditional or nuclear family. This is a two-generation family, the father and the mother and their own children. Most couples wanted to have four children, two boys, two girls. Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations. This kind of family with grandparents, parents, and grandchildren is called an extended family. This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter. This is more possible now that American homes have become larger. What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits. Now, the fatherless or motherless family is one kind of what we call a single-parent family. In the fatherless family it's just the mother and her children. As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce. There are also a growing number of motherless families--where the father raises the children, for any of the same reasons. A motherless family may also be fatherless, but still a family with one adult. This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work. One other new kind of family is becoming increasingly more common. A single parent with one or more children will marry again. Perhaps the other parent is also a single parent. Together they will start what is called a blended family, which blends together or combines the children from two other families.

单选题 ______ had he arrived home than it began to rain.

单选题 Teaching children to read well from the start is the most important task of elementary schools. But relying on educators to approach this task correctly can be a great mistake. Many schools continue to employ instructional methods that have been proven ineffective. The staying power of the 'look-say' or 'whole-word' method of teaching beginning reading is perhaps the most flagrant example of this failure to instruct effectively. The whole-word approach to reading stresses the meaning of words over the meaning of letters, thinking over decoding, developing a sight vocabulary of familiar words over developing the ability to unlock the pronunciation of unfamiliar words. It fits in with the serf-directed, 'learning how to learn' activities recommended by advocates of 'open' classrooms and with the concept that children have to be developmentally ready to begin reading. Before 1963, no major publisher put out anything but these 'Run- Spot-Run' readers. However, in 1955, Rudolf Flesch touched off what has been called 'the great debate' in beginning reading. In his best-seller Why Johnny Can't Read, Flesch indicted(控诉)the nation's public schools for miseducating students by using the look-say method. He said-and mere scholarly studies by Jeane Chall and Rovert Dykstra later confirmed-that another approach to beginning reading, founded on phonics(声学), is far superior. Systematic phonics first teaches children to associate letters and letter combinations with sounds; it then teaches them how to blend these sounds together to make words. Rather than building up a relatively limited vocabulary of memorized words, it imparts a code by which the pronunciations of the vast majority of the most common words in the English language can be learned. Phonics does not devalue the importance of thinking about the meaning of words and sentences; it simply recognizes that decoding is the logical and necessary first step.

单选题 What's the best way to protect a tender, green seedling from the hungry stomach of deer? Give the seedling bad breath! The same chemical that gives people bad breath after they have eaten garlic can save small trees from being eaten by animals. A kind of chemical selenium (硒), which is also found in garlic, is planted in the soil near a young tree. The tree's roots absorb the selenium which is then carried to the leaves. From there the selenium is used to form a chemical called dimethyl selenide (乙烷硒化物)—the same chemical made in the human mouth after eating garlic. As deer wander around looking for food, they smell the seedlings' leaves and leave the plants alone. The selenium is important. Why? Because each year deer eat millions of dollars' worth of trees farm seedlings. So far, selenium has been tested only on Douglas fir (枞树) seedlings, but researchers think they could protect fruit trees and garden plants, too.
