Theylivedontheearthtensofmillionsofyearsago,longbeforehumanscameintobeingandtheirfutureseemedsecureatthattime.

本句是一个由and连接的并列句，其中，longbefore引导时间状语从句，进一步解释说明tensofmillionsofyearsago，意为“在……之前很久”。注意：beforelong意为“不久以后”。如：IknewTomlongbeforeIknewyou.我在认识你之前很久就认识汤姆了。Wehopetofinishourexperimentbeforelong.我们希望不久就把实验做完。It___longbeforewe___theresultoftheexperiment.A.willnotbe;willknowB.is;willknowC.willnotbe;knowD.is;know

beforelong不久以后e.g.Ihopetoseeyouagain

beforelong.

ontheearth

在地球上。在earth,sun,moon等表达世界上独一无二的名词前,要加the。

comeintobeing的意思是“开始存在;发生”。我们不知道这世界是什么时候存在的。Wedon’tknowwhentheworldcameintobeing.2.Whenscientistsinspectedthebones,theyweresurprisedtofindthatthesedinosaurscouldnotonlyrunliketheothersbutalsoclimbtrees.

本句中的tofindthat...是不定式作原因状语。不定式用来表原因时，常修饰表示情感、心理状态、性格等的形容词，如：happy，glad，lucky，fortunate，surprised，angry，anxious，cruel，clever，frightened，shocked，sorry，eager，proud，disappointed，foolish，impatient，unwise，naughty等。如：Weweresurprised

toseehim.我们真想不到会见到他。Weareproud

tobeyoungpeopleofnewChina.作为新中国的青年，我们感到很骄傲。Youwerefoolish

toactlikethat.你那样做很愚蠢。3.Somescientiststhinkitcameafteranunexpectedincidentwhenahugerockfromspacehittheearthandputtoomuchdustintotheair.

本句中when引导定语从句，其先行词为incident。关系副词when的先行词一般是表时间的名词，如:HecamelastnightwhenIwasout.

但有时并不直接是表时间的名词，如：In1921EinsteinwontheNobelPrize,andwashonoredinGermanyuntiltheriseofNazismwhenhewasdrivenfromGermanybecausehewasaJew.1921年爱因斯坦获得了诺贝尔奖，他在德国很受尊敬。纳粹上台后由于他是犹太人而被赶出了德国。4.AccordingtoaUNreport,….
