专业四级：词汇、语法详细解答3Test Sixteen含蓄条件句中的虚拟语气1)由介词短语引起：But for their help ,we wouldn’t have succeeded.His progress wouldn’t have been made without arduous work.2)由表示转折语气的词语引起：I was too busy yesterday. Otherwise I would have been here to see you.3)根据上下文判断：Anyone in his position would have done the same.近义词辨析purpose, aim, goal, end这组词均含有“目的，目标”的意思。

purpose是一般用语，强调实现目标的决心。

aim常指具体的近期奋斗目标或计划。

goal强调个人精心选定的，含有不达目的誓不罢休的意思，也有足球“球门”之意，又引申为经过艰苦努力才可达到的目标。

end比较正式，指心目中怀有的目的。

例如：He went to new York City for the mere purpose of seeing 42nd avenue.他去纽约只是为了看看四十二大道。

Her aim is to marry a westerner and live abroad.她的目标是嫁给西方人，住到国外。

We have been fighting for one common goal.我们一直为了一个共同的目标奋斗。

He never achieved his end.他从未达到目的。
