這個(gè)公式能幫你預(yù)測(cè)你家孩子身高

Would you like to know if your child is set to stand head and shoulders above the rest? Or if they're likely to stay diminutive into adulthood?

想知道你家孩子將來的身高會(huì)鶴立雞群?jiǎn)?還是會(huì)一直這么矮下去?

There is an easy (although fallible) mathematical equation that can help you predict how tall your child will be.

有一個(gè)簡(jiǎn)單(但不一定靠譜)的數(shù)學(xué)公式可以幫你預(yù)測(cè)孩子未來的身高。

The formula, which has been used since the 1970s and was revealed in the New York Times, predicts that 'most (but not all) children will reach a height somewhere within a fairly small range that can be estimated by the average combined heights of their parents.'

該公式自上世紀(jì)70年代開始流行，發(fā)端于《紐約時(shí)報(bào)》。公式稱，“根據(jù)父母的平均身高總和，可以推算出孩子身高的波動(dòng)范圍，這個(gè)波動(dòng)范圍很小。大部分(并非所有)孩子適用這個(gè)規(guī)律。”

How does it work?

具體怎么算呢?

BOYS

男孩

Add the heights of both parents plus 5in (13cm) and divide by two.

父母身高相加，總和再加5英寸(13厘米)，用結(jié)果除以2。

比如父親1米76，母親1米65，那兒子的身高就是(1.76 + 1.65 + 0.13)/ 2 = 1.77，即1米77。

GIRLS

女孩

Add the heights of both parents minus 5in (13cm) and divide by two.

父母身高相加，總和減去5英寸(13厘米)，用結(jié)果除以2。

比如父親1米76，母親1米65，那女兒的身高就是(1.76 + 1.65 - 0.13)/ 2 = 1.64，即1米64。

There is a more complicated formula for extreme differences in parental height.

父母身高差距比較大的話，需要用另一個(gè)復(fù)雜點(diǎn)兒的公式。

These predictions are by no means completely reliable, however, as environmental factors such as nutrition play a big part in determining human height.

不過這種預(yù)測(cè)不可能完全準(zhǔn)確，因?yàn)檫€要考慮環(huán)境因素，比如營(yíng)養(yǎng)狀況就會(huì)對(duì)身高發(fā)揮重要影響。

Genetics is estimated to account for between 60 and 80 per cent of one's final height.

基因約占所有影響身高因素的60%至80%。

A study of 8,798 pairs of Finnish twins conducted in 2000 found that genetics accounted for 78 per cent of height in adult men and around 75 per cent in women.

2000年，一項(xiàng)針對(duì)8798對(duì)芬蘭雙胞胎的研究顯示，基因?qū)δ行陨砀叩挠绊戇_(dá)78%，對(duì)女性達(dá)75%。

However, as we all know not all children born to the same couple will be the same height.

不過正如我們所知，同一對(duì)父母，其所有孩子的身高不一定會(huì)是相同的。

Science shows that height tends to decrease in younger siblings.

科學(xué)研究證明，后出生的孩子身高會(huì)傾向于變矮。

Another popular method for predicting height is to double a boy's height at age two or a girl's height at 18 months.

另一個(gè)著名的預(yù)測(cè)未來身高的方法是：男孩兩歲時(shí)的身高乘以2;女孩18個(gè)月時(shí)的身高乘以2。

Most children will reach an adult height within 4in (10cm) of this estimation.

大部分孩子長(zhǎng)大后的身高會(huì)在這個(gè)預(yù)估數(shù)值的上下4英寸(10厘米)范圍內(nèi)波動(dòng)。
