题目释义：To develop…, demographers would have to…more than now they do about… 考点 比较结构 1)关于economic和economical economic 是"经济上的"，economical是"节约的"。 economic [only before noun]PE relating to trade, industry, and the management of money Economic growth is slow. the government's economic policy Economic reform is needed. In the current economic climate (=conditions), we must keep costs down economical =cheap or not wasteful. 选项分析 (A) a great deal与now比较(than后面只有一个成分now，所以a great deal只有与其进行对比)，概念不对等?now作为状语没有与其平行的副词，所以than后面需要有成分能够与a great deal平行，一个好的解决方法是than后面补出主谓，使than前后形成句子的平行，补出谓语的原因是使比较对象没有歧义。 (B) economic的意思是：relating to trade, industry, and the management of money，而economical为便宜or节省的意思，根据逻辑含义应该用economic。 (C) economical使用错误。 (D) Correct；本句使用would have to还是have to都可以(详见补充说明)。 (E) a great deal与now比较，概念不对等 。 补充说明 would have to know是不很肯定的语气，其表达的是have to do的内容只是一个假设，并不是真的"必须"，而have to表达的意思是，要做的事情非常重要，"必须"去做。在本题中两种含义都合理，因此没有必要做这样的区分。 类似题链接 大全10.

【误认为是错误选项】 我主要认为不应该是would have to 应该直接是have to。但其实用would have to 不算错，因为这是一种contrary-to-fact的情况，可以使用虚拟语气。【需要好好积累一下虚拟语气的用法了！！】

首先，economical是节俭的意思，排除，另外后面要有they do。 其次，至于说是否有would这个无所谓 记住：to do..., sb （would）have to....（不存在时态不对等问题）

必须有more than they do now中的“they do”，否则比较的前后不平行

would have to know是不很肯定的语气，其表达的是have to do的内容只是一个假设，并不是真的"必须"，而have to表达的意思是，要做的事情非常重要，"必须"去做。在本题中两种含义都合理，因此没有必要做这样的区分。

平行结构排除AE;根据时态排除B，CD相比economic和economical的意思，前者是经济上的，后者是侧重节约

from beatthegmat killer1387 wrote: To top the list, Mark has to study hard. ... this is what he has to do right now. Quote: To top the list, Mark will have to study hard. ... at some point in the future. (that could be twenty years from now or two minutes from now, but it can't be right now.) Quote: To top the list, Mark will study hard. this refers to something mark will do in the future. this sentence also conveys a fair degree of certainty that mark will actually “top the list”. as an analogy, if i write To power the lightbulb, i will stick two electrodes into a potato, i am implying that this strange method will actually succeed in powering the lightbulb. Quote: To top the list, Mark would have to study hard. ... implies that mark is not actually going to do this. (a more complete context for this that would be something like To top the list, Mark would have to study hard; however, he prefers to relax and get mediocre scores instead.) Quote: To top the list, Mark would study hard. in terms of objective meaning, this sentence isn’t very different from the preceding one. however, the previous sentence emphasizes the responsibility or obligation of studying (hence “would have to”), while this sentence emphasizes the actual act of studying.

would have to的语气比have to弱，此处都合理，在now处区分
