第一第二个我也不知道怎么分析,其它给一个参考。欢迎拍砖。
Three percent of beer volume is alcohol, compared with wine's twelve percent and whiskey, cognac, and rum's forty percent. A. Three percent of beer volume is alcohol, compared with wine's twelve percent and whiskey, cognac, and rum's forty percent C. By volume, beer is three percent alcohol, compared with wine, which is twelve percent alcohol; whiskey, rum and cognac are each forty percent alcohol E. The percentage of beer volume that is alcohol is three; that of wine is twelve, and that of whiskey, cognac, and rum is forty. Why choose C? 比较对象对等A wine’s 没有对比对象;E应该是that of wine volume…. Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings. B movies—fewer than have been D movies, a number lower than the people B 比较结构做状语,类似于more than **在句子结尾的用法。 D要用完成时? A number要根number对比不能跟people. In good years, the patchwork of green fields that surround the San Joaquin Valley town bustles with farm workers, many of them in the area just for the season. (A) surround the San Joaquin Valley town bustles with farm workers, many of them (E) surrounds the San Joaquin Valley town bustles with farm workers, many are A E句子run-on。A也有歧义them可以指代fields. In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are. (A) have been priced to sell, and they are (C) are priced to sell, and they do C 句子意思是他们的酒标价出售,他们这样做了。不需要用完成时(表示price在they do之前)。另外最后补充动词最好补充助动词而不是系动词。
One pervasive theory explains the introduction of breakfast cereals in the early 1900s as a result of the growing number of automobiles, which led to a decline in horse ownership and a subsequent grain glut; by persuading people to eat what had previously been horse feed, market equilibrium was restored. (B) persuading people to eat what had previously been horse feed restored market equilibrium (D) the persuasion of people to eat what had previously been horse feed restored market equilibrium (E) market equilibrium was restored when people were persuaded to eat former horse feed B 动名词结构做主语是否显得头重脚轻? persuading表示这个动作导致了这个结果,而不是persuasion这个现象导致了这个结果。而E用了被动不必要另外改变句子重心,原来的主语变成了状语。 More than thirty years ago Dr. Barbara Mc-Clintock, the Nobel Prize winner, reported that genes can “jump,” as pearls moving mysteriously from one necklace to another. (A) as pearls moving mysteriously from one necklace to another (B) like pearls moving mysteriously from one necklace to another B 在这个比较里as表示一个实实在在的动作比较,另外as引导从句而不能用moving. Like这儿表示一个虚拟的比较,并不是实际发生的。 The work of mathematician Roger Penrose in the early 1970s, on the geometry of what are called aperiodic tiles, turned out to describe the architecture of a previously unknown class of crystals. (A) what are called aperiodic tiles, turned out to describe (B) what is called aperiodic tiles, describes A B中的describes时态不正确,in the early 1970s.时间状语。另外tiles是复数所以最好用are。 The particular design of muscles and bones in the neck and limbs of the turtle allow that it can draw in its exposed parts such that an attacker can find nothing but hard shell to bite. A. allow that it can draw in its exposed parts such that B. allow it to draw in its exposed parts, and so C. allows for it to draw in its exposed parts and that D. allows that it can draw in its exposed parts, and so E. allows it to draw in its exposed parts, so that Why choose D? Design为主语用allows,CE都是run-on结构。C中that没有与之平行的。E中so that不能直接跟句子。 |
