Officials at the United States Mint believe that the Sacagawea dollar coin will be used more as a substitute for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than four quarters, which weigh 5.67 grams each.
more as a substitute for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than
more as a substitute for four quarters than the dollar bill because it weighs only 8.1 grams, far lighter than
as a substitute for four quarters more than for the dollar bill because it weighs only 8.1 grams, far less than
as a substitute for four quarters more than the dollar bill because its weight of only 8.1 grams is far lighter than it is for
as a substitute more for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than it is for
这里的lighter和less其实区别不大，less甚至可以看作为less heavy的简写。选项B主要的错误在dollar应该为for dollar上。
当然可以的。weighs lighter than 不成立，因为lighter只能做形容词！不能修饰weighs。曼哈顿278页登录 或 注册 后可以参加讨论
far...than后面是有省略的
D错在： it的同物指代，两次it指代不一样
dollar bill前没有介词for 不平行
B&D.-By eliminating the "for" prior to "the dollar bill," This choice creates an ambiguity: Is the dollar coin being used more as a substitute for four quarter than for the dollar bill, or is the dollar coin being used more than the dollar bill as a substitute for four quarters?
因为more的位置，B的意思歧义，“ dollar coin作为 four quarters的替代品比作为dollar bill的替代品多“，但实际要表达的意思是” dollar coin作为 four quarters的替代品比作为dollar bill的替代品更合适“；
另外，后半句，是重量在比较，而不是两个主语（物体）在比较，所以用less不用light
B&D.-By eliminating the "for" prior to "the dollar bill," This choice creates an ambiguity: Is the dollar coin being used more as a substitute for four quarter than for the dollar bill, or is the dollar coin being used more than the dollar bill as a substitute for four quarters?
B的前面部分拆解开来就是：S was used more as a substitute for four quarters than as the dollar bill，这里要表达的意思是S是four quarters的替代品而不是dollar bill的替代品，它只能替代4个1/4美元的硬币，而不能替代美元钞票，因为纸币比S coin更轻。
C, it weighs only 8.1 grams, far less than four quarters, 这里是宾语和宾语比较，暗示four quarters拥有不同的宾语，ok
你好，请问这个far less/lighter thanxxxx是什么成分?修饰主语宾语都可以吗？
the Sacagawea dollar coin weighs only 8.1 grams, far lighter than four quarters，后面部分是伴随状语，修饰weighs only 8.1 grams这件事，逻辑主语是the Sacagawea dollar cointhe Sacagawea dollar coin weighs only 8.1 grams, far less than four quarters，后面部分是定语，修饰8.1 grams。
形容词可以做定语、状语、同位语，主要根据语意几修饰对象看它做的什么成分
形容词是可以做伴随状语的，如：Happy about his raise, Bill celebrated by taking his friends out to dinner.

its weight 比较用lighter
de ， 句尾it is for错误繁琐，都是weight，可以省略
数字的比较，用more/less
because its weight, only 8.1 grams, is far less than it is for
注意前后的错误都要找
e.more...rather than错误
its weight of only 8.1 grams is far lighter than it is for……，比较的是weight这个东西，weight is lighter
b. (8.1 grams) far less than four quarters比较不对等
d.its weight 和it不对等
e.more...rather than错误
