GWD 21-1 D
According to analysts, an alliance between three major personal computer companies and most of the nation’s largest local telephone companies would enable customers to receive Internet data over regular telephone lines with speeds much higher than is currently possible.
A. with speeds much higher than is
B. with speeds that are much higher than are
C. at much higher speeds as are
D. at much higher speeds than that (E)
E. at speeds much higher than are
D的错是否为违反平行结构? at much higher speeds 与at speeds much higher 有区别否?E中的are后补全为什么?
GWD 21-27 D
The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.
A. to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs
B. to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing
C. is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs
D. is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs (B)
E. is the world’s smallest network digital camcorder, the length of which is that of a handheld computer, weighing
答案为B，我选D，原因：
B的问题：
1． Claim to be一般用来连接动作的发起人和宾语，如 sb claim to be what,what和sb是同一回事；这里，it显然不能是the world’s smallest network digital camcorder, 所以不能用Claim to be，否则逻辑意义不对；
2． Which跳跃修饰不是首选；
3． Weighing在句尾，修饰对象语法上有歧义；
D的好处：
1． what it claims is the world’s smallest network digital camcorder，what是claim的宾语和is的主语，逻辑意义正确；
2． Which直接修饰camcorder，无歧义；
3． Weighs用作谓语形式，语法和逻辑意义上均准确，无歧义。
请NN指点。
GWD 21-33 B
One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream. Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled “SuperOXY,” that has extra oxygen dissolved in the water. Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed bye the muscles is through the lungs.
Which of the following, if true, would serve the same function in the argument as the statement in boldface?
A. the water lost in exercising can be replaced with ordinary tap water
B. the amount of oxygen in the blood of people who are exercising is already more than the muscle can absorb
C. world-class athletes turn in record performance without such water
D. frequent physical exercise increases the body’s ability to take in and use oxygen (A)
E. lack of oxygen is not the only factor limiting human physical performance
问same function, 需要和原文一样作为原因，支持Such water would be useless in improving physical performance；
答案为A，说“运动中流失的水份可以通过日常的TAP WATER补充”，说明运动需要补充水，那么这种SuperOXY的水也可以补充；但是补充水中的氧气能否被身体吸收，增加performance不得而知，所以不能支持也不能削弱水无用的结论；
答案B，说“运动的人血液内的氧气含量已经超过了肌肉可以吸收的含量”，正好说明其他增氧方式都是无用的，支持了结论。
因此，认为答案应该为B，请指教。
GWD 21-34 C
Scientists have dated sharp-edged flakes of stone found in the fine-grained sediments of a
dry riverbed in the Afar region of Ethiopia to between 2.52 and 2.60 million years ago,
pushing back by more than 150,000 years the earliest date when it is known that humans
made stone tools.
A. when it is known that humans made
B. at which it is known that humans had made
C. at which humans are known to have made
D. that humans are known to be making (C/A)
E. of humans who were known to make
我选C，不知A和C有什么区别？
感觉上A说的是“知道人类制造石器的时间”，而C说的是“可知的人类制造石器的时间”，好象用C更符合逻辑意思。不清楚，请指点。
