12.翻译：原子结构就好像缩小了的太阳系。
as it were是好像的意思，是插入语，虚拟语气。as if也是好像的意思但是加了be动词之后就变成一个句子有两个be动词，错误。
13.翻译：我们需要机器部分是由铸铁制作而成的。
be made of 用...造成(用于原材料显而易见的场合)
be made from 由...所做成的(用于原材料不易看出的场合)
宾语从句中遇到命令式的词，如：order, suggest, propose, require, demand, request用虚拟语气。
We required that the machine parts （should）be made of cast iron.
14.翻译：管理力求产品消耗显著减少。
虚拟语气，理由同上。（should）be further reduced
9.翻译：正是你开始工作的时候了。
it is high time that...后面的从句谓语动词要用过去式或用should加动词原形,should不可省略。
10.问题出现在会议上：我们是否有足够的资金进行我们的研究。
12.这个会议是持续两天还是三天是没关系的。
whether... or... 是...还是... 固定搭配
另一个理由：当宾语从句提到句首时，只能用whether引导，不能用if
12.原子的结构，从某种程度上看，就是一个小型太阳系。as it were是固定词组，意思是：可以说，从某种程度上。
13.我们要求机器部件由铸铁制成。require后宾语从句用虚拟语气，这里是省略了should(or would)，后接动词原型。
14.管理层强调生产成本还应进一步降低。urge后宾语从句用虚拟语气，这里是省略了should(or would)，后接动词原型。
9.你真该开始工作了。It's high time也为虚拟语气，后面的从句用过去时表示应该做某事而未做。
10.我们是否有足够的钱用作研究，这作为一个问题在会议上提出。wheth
