(1) If you say "twice as many", then this construction should be paired with acountable noun. e.g., twice as many dogs --> "dogs" is a countable noun (2) If you said "twice as much", then this construction should be paired with anuncountable noun. e.g., twice as much water --> "water" is an uncountable noun (3) If the noun in question is already an explicitly numerical quantity, then you should use neither "much" nor "many". instead, you should just use "twice" or "double" by itself. e.g., twice the increase --> "increase" is an explicitly numerical quantity (4) These rules are followed pretty closely. so, for instance: twice as much water --> correct, since "water" is an uncountable noun (but is not an explicitly numerical quantity) twice the water... --> incorrect, since water is not a numerical quantity twice as much as the increase... --> incorrect; redundant twice the increase... --> correct 注意应该看the increase所指向的东西。
Many用法错误,因为the increase不是一个 countable quantity(这里the increase可以看做是一个代词,而它所指代的对象就是前面出现过的内容:the number of the people,而the number of the people是一个表达数量的数字而不是可数名词,所以 the increase也不能够用many来修饰);twice as many as是同位语修饰词(appositive modifier),要紧接其修饰的内容,在此句子中逗号前不是一个figure,所以不能用twice as many as这个结构,awkward。(见下面知识点补充 1);the increase in previous year错误。
twice as many as是同位语修饰词(appositive modifier),要紧接其修饰的内容,在此句子中逗号前不是一个figure,所以不能用twice as many as这个结构
in this case, you can't use "..., twice as many as...", because that's an appositive modifier. appositives must modify some noun that comes IMMEDIATELY before the comma, which in this case would have to be whatever figure is twice whatever other figure. since no such figure is given, you can't use this construction.
the increase in previous year错误;the increase表抽象名词不能用many修饰
increase不可数,不能用many

twice the A or double the A, 这里A是一个有明确数值的概念,例如increase,population等。twice as much/many 则是一些事物,例如苹果等。
as many as the increase 错误。increase是不可数名词
