第162句:
This would be neither here nor there if it weren't for the observation that having an older mother seems to be an independent risk factor for obesity.
如果不是发现生育年龄的增长似乎是导致肥胖的一个独立风险因素,以上数据并无太多的实际意义。
六级词汇讲解:
本句的主干是This would be...o短语neither here nor there作主句的表语。 if引导的是含有虚拟语气的条件状语从句,其中,that引导的定语从句that having an older mother...for obesity修饰observation。
neither here nor there意为“无关紧要的,不相干的”。如:
Whether you go to the movie or stay at home is neither here nor there.
你去看电影还是待在家里都不重要。
independent意为“不相干的,独立的”。如:
Linda is old enough to be independent ofher parents.
琳达年龄够大了,可以不依赖父母而自立了。
六级考点归纳:
if引导的条件状语从句运用虚拟语气一般有以下几种情况:
表示与现在事实相反的假设,从句采用一般过去时,主句谓语部分为would/should+动词原形。如:
If they were here,they would help us.
他们要是在这儿的话就会帮我们。
表示与过去事实相反的假设,从句采用过去完成时had done,主句谓语部分为should/would+have doneo如:
If you had worked harder,you would have succeeded.
你要是再努力一些就会成功了。
Ifyou had come yesterday,I should have told you about it.
要是你昨天来,我就告诉你这件事了。
表示对将来情况的假设,从句可采用一般过去时、were+不定式、should+动词原形,主句谓语部分为should/would+动词原形。如:
If you succeeded/were to succeed/should succeed, everything would be all right.
你要是成功了,一切都会变好的。
