请问“For every hour they work,they can get thirty dollars?前半句是倒装句吗?还是?

不是倒装句,是定语从句.
they work修饰For every hour.
意思是他们工作的每个小时.
如：The food you eat can make you energetic.是定语从句.you eat修饰The food
意思是你吃的食物
1) 为了避免句子部分内容不必要的重复,常用so + be动词（助动词、情态动词）+主语或neither / nor + be动词（助动词、情态动词）+主语的倒装句式.其中第一个句式表示与前面所述的肯定情况相同,第二个句式表示与前面所述的否定情况相同.例如：
His brother is a college student; so is mine.
他弟弟是大学生,我弟弟也是.
2）具有否定意义的词或短语置于句首时（除否定词修饰主语外）,句子一般要写成部分倒装句.这类词或短语常见的有：not,never,seldom,hardly,rarely,scarcely,by no means,under no circumstances,in no way,at no time,no sooner … (than),hardly … (when),not only … (but also),not until… ,等.例如：
Hardly had she sat down when she heard someone knocking at the door .
她还没来得及坐下来,就听见有人敲门.
Not until twelve o'clock did he go to bed last night .
3）当so,often,only等表示程度、频率的副词放在句首时,句子一般要倒装.例如：
Only in this way can you come up with a solution to the problem.
只有这样,你才有可能想出解决这个问题的办法.
So serious was the situation that everybody faced a test.
形势如此地严峻,每个人都面临着一场考验.
4）当there,here,then,now等副词在句首,且谓语是come,go,be等动词时,句子一般要全部倒装.其意义在于引起他人的注意.如果这类句子的主语是代词,则不用写成倒装句.例如：
Now,here goes the story.这个故事是这样的.
Look,there comes the taxi.瞧,出租车过来了.
Then came another question.然后又一个问题提出来了.
5) 当out,in,away,up,bang等表示方位或拟声词放在句首时,句子一般要全部倒装.这类子比自然语序的句子更为生动、形象.但如果这类句子的主语是代词,则不用写成倒装句.例如：
Bang goes my ace.我砰地一下打出了A.(扑克牌中的点数)
Away flew the bird.那鸟飞走了.
6) 其他情况还有：省略了if的虚拟条件句、某些表示祝愿的句子、以及某些让步状语从句,等等也要用倒装句式.例如：（省略了if的虚拟条件句）
Had they not helped us,we could not have done it so successfully.
如果没有他们的帮助,我们不可能把那件事办的如此成功.
7) 由于修辞或是平衡句子的原因也可以用倒装句；也可以不用.这不是一条必须的规定.
Next to this one is another grand hotel which is beautifully decorated .
这家饭店隔壁还有一家装修华丽的大饭店.
