162. 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.
譯文
如果不是發(fā)現(xiàn)生育年齡的增長(zhǎng)似乎是導(dǎo)致肥胖的一個(gè)獨(dú)立風(fēng)險(xiǎn)因素，以上數(shù)據(jù)并無(wú)太多的實(shí)際意義。
點(diǎn)睛
本句的主干是This would be...。短語(yǔ)neither here nor there作主句的表語(yǔ)。if引導(dǎo)的是含有虛擬語(yǔ)氣的條件狀語(yǔ)從句，其中，that引導(dǎo)的定語(yǔ)從句that having an older mother...for obesity修飾observation。
neither here nor there意為“無(wú)關(guān)緊要的，不相干的”。如：
Whether you go to the movie or stay at home is neither here nor there. 你去看電影還是待在家里都不重要。
independent意為“不相干的，獨(dú)立的”。如：
Linda is old enough to be independent of her parents. 琳達(dá)年齡夠大了，可以不依賴父母而自立了。
考點(diǎn)歸納
if引導(dǎo)的條件狀語(yǔ)從句運(yùn)用虛擬語(yǔ)氣一般有以下幾種情況：
表示與現(xiàn)在事實(shí)相反的假設(shè)，從句采用一般過(guò)去時(shí)，主句謂語(yǔ)部分為would/should＋動(dòng)詞原形。如：
If they were here, they would help us. 他們要是在這兒的話就會(huì)幫我們。
表示與過(guò)去事實(shí)相反的假設(shè)，從句采用過(guò)去完成時(shí)had done，主句謂語(yǔ)部分為should/would＋have done。如：
If you had worked harder, you would have succeeded. 你要是再努力一些就會(huì)成功了。
If you had come yesterday, I should have told you about it. 要是你昨天來(lái)，我就告訴你這件事了。
表示對(duì)將來(lái)情況的假設(shè)，從句可采用一般過(guò)去時(shí)、were＋不定式、should＋動(dòng)詞原形，主句謂語(yǔ)部分為should/would＋動(dòng)詞原形。如：
If you succeeded/were to succeed/should succeed, everything would be all right. 你要是成功了，一切都會(huì)變好的。
