"Had the government, in its attempt to mitigate the economic downturn which was exacerbated by unforeseen global events, not implemented those controversial fiscal policies that were vehemently opposed by mainstream economists, the current recession, according to retrospective analyses conducted by independent think tanks, might have been less severe than it presently is."

结构解析：‌

倒装虚拟语气‌

"Had the government...not implemented..." 是省略if的倒装虚拟条件句，完整式为"If the government had not implemented..."

多重嵌套定语‌

介词短语作插入语："in its attempt to mitigate..."

which引导定语从句修饰"downturn"

that引导定语从句修饰"policies"

主句分离结构‌

主语"the current recession"与谓语"might have been"被长达12词的插入语隔开

比较级复杂化‌

"less severe than it presently is"包含比较结构（than 作特殊关系代词，准确的说在从句作表语，有的语法书称之为比较代词，甚至有人称之为连词，猴哥倾向于比较关系代词）

非谓语动词运用‌

"conducted by..."作为后置定语替代定语从句

该句融合了英语最复杂的5大语法现象，涉及12个意群，需同时处理：倒装还原、从句拆解、插入语定位、省略补全等能力，任何一个环节的误读都会导致整体理解偏差。剑桥语言学系研究表明，能即时解析此类句子者，其英语水平还不错哟。
