Providing initial evidence that airports are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago metropolitan area.
迷惑选项好想选.as much annually as is emitted by the
OA.that emitted annually by all
Why B wrong 1. main point is 无 // total amount of pollutant emitted (used as a modifier, not verb) annually by vehicles at O’Hare International Airport is twice as much annually as is emitted by the motor vehicles… Ron: the real problem is that "is" has no parallel in the first part of the comparison - i.e., the first part doesn't say "is emitted" or "are emitted" - and so the comparison is wrong. 2. redundancy amount X is twice as much as amount Y --> inferior, and possibly even wrong (redundant)
amount X is twice amount Y --> undoubtedly better 3. annually的位置 the correct answer is structured like this:
the total amount of pollutant emitted annually by vehicles at the O'hare International airport is twice that emitted annually by xxxxx
this actually makes sense.
each part is "the amount emitted annually by xxyyzz", and those two (similarly structured) parts are linked together by the "twice..." comparison.
__
choice B, on the other hand, is structured like this:
the total amount of pollutant emitted annually ... is twice as much annually as is emitted by xxxxx
this makes no sense.
since "annually" is already in the pink part -- the comparison -- it already applies to both parts.
so, the additional use of "annually" in the first blue part is redundant.
also, the two blue parts aren't parallel -- one is expressed as an annual rate, and the other isn't. Correct usage of twice — from Ron Purewal > < there are three different kinds of acceptable uses of "twice":
1) twice NOUN/PRONOUN, where the noun or pronoun describes a numerical quantity of something;
2) twice as ADV/ADJ (as)... / twice this/that ADV/ADJ
3) twice by itself, meaning that something has happened two times (e.g., i've been there twice).
#3 is the only one of these constructions in which you might see "twice" followed by "of" -- and then only if they're independent constructions.
for instance, you could say
smith has already been advised twice of the foolishness of these actions.
... notice that this construction is NOT "twice of"; the "of" is part of the boldfaced construction, but the "twice" is not.
note that, in #1, there may be possessives and/or adjectives in front of the NOUN. 一些Q&A Usage : X is twice that Y this isn't a construction.
you're only going to have "twice that..." in one of the following 2 cases:
1) "that" is a relative pronoun (e.g., the unemployment rate of Country X is twice that of Country Y)
2) they're part of independent constructions (e.g., smith has already been advised twice that these actions are foolish)
1)Th total money i have is twice that you have. incorrect -- this "that" is not a relative pronoun such as the one above.
2)The total money i have is twice of what you have.
3)the total money i have is twice of that you have. both incorrect -- "twice of X" is never correct as a single construction.
4)the total money i have is twice as much as you have. "twice as much as you have" is ok.
"total money" isn't, though; you'd have to say "the amount of money" or "the total amount of money".
5)the total money i have is double of what you have. incorrect -- the correct construction is "double X", not "double of X".
6)The number of books i have are twice that you have. incorrect, same reason as #1
also, note that "the number ... are ..." is incorrect in all of these sentences; "the number" is singular, so the verb should be "is".
7)The number of books i have are twice as many as you have. "twice as many as ..." is a correct construction.
you can't say "the number is twice as many", though -- that's a redundant construction.
you'd just say "i have twice as many books as you have."
8)the number of books i have are twice of as many as you have wrong. can't have "twice of X". —— "Twice that you have" doesn't work.
Consider the following examples, each of which could be the second half of a comparison:
...twice the amount that you have
...twice the quantity that you have
etc.
With "that" (= pronoun) in there, you'd need ...twice that that you have. That's absolutely unreadable, of course, so you'll never see it. |
