Providing initial evidence that airport 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. 1. as much as that which is being emitted annually by all 2. as much annually as is emitted by the 3. as much compared to what is annually emitted by all 4. that emitted annually by all 5. that emitted annually compared to the 答案 4. 考的是倍数表达式 倍数+形容词. xx times taller than something or xx times as tall as something
回到此题. the amount ... is twice something. 1. that which 不好. "that that" is better, 可是仍旧不够好. 2. 没有something 3. as 不配对. 4. that emitted annually by all. something 是that, that (that) emitted annually by all. 5. compared to 是多余的,twice 已经在表示比较了.
这里有点瑕疵哈·我认为twice是不能直接加名词N的·必须是twice the number/the rate/the price/the size之类的。如果是twice people之类的肯定错，（除了twice日期）因为twice是副词不是adj。这题其实不是twice 直接加something，而是that指代了the amount of pollution。
In 1914 a total of 469,000 cars and trucks were produced in the United States, but in 1929 almost twice the numbers of tucks alone came off the assembly lines. A. the numbers of trucks alone B. that number of trucks alone C. the number of trucks by themselves D. as many trucks themselves E. as many trucks by themselves
这个题到现在谁能解释一下 but之后的分句主谓宾？that指代前一个数字 那么之后 number of ... 的用法出自何处？

考点: 平行对称(Parallelism) 逻辑表达(Logical Predication) 1)比较对象必须要概念对等 3) 用and连接的对象必须是平行对象 (A) as fast as的前后是一个动作(are growing)和一个名词(growth rate)进行比较,比较概念不对等 (B)比较概念不对等.后一个分句的allotment cut and raising不对等. (C) 逻辑意思不正确,原句的意思是供应商养殖鱼类的生长速度和鱼类自然生产速度作比较,该选 项中growing them和growing fish构成平行,将原句的意思更改为供应商养殖鱼类的生长速度和供 应商自然养殖鱼类的速度做比较, (D) 正确,正确的表现了原句的逻辑意思,既供应商养殖鱼类的生长速度和鱼类自然生产速度作比较 (E) 后一个分句中and raising them没有平行的对象. 句子结构: To meet…, suppliers are growing fish twice as fast as…
这个事网上搜到的解释。 我做出答案的顺序是。可以先从划线后半部分的平行确定cutting，从而排除BE。 然后A选项their natural growth rate和前面they are growing fish 不平行，排除 然后CD选项就是原文意思的表达了。这一点上面的解释得很清楚
