本句是一個(gè)由and連接的并列句，其中，longbefore引導(dǎo)時(shí)間狀語從句，進(jìn)一步解釋說明tensofmillionsofyearsago，意為“在……之前很久”。注意：beforelong意為“不久以后”。如：IknewTomlongbeforeIknewyou.我在認(rèn)識你之前很久就認(rèn)識湯姆了。Wehopetofinishourexperimentbeforelong.我們希望不久就把實(shí)驗(yàn)做完。It___longbeforewe___theresultoftheexperiment.A.willnotbe;willknowB.is;willknowC.willnotbe;knowD.is;know

ontheearth

在地球上。在earth,sun,moon等表達(dá)世界上獨(dú)一無二的名詞前,要加the。

comeintobeing的意思是“開始存在;發(fā)生”。我們不知道這世界是什么時(shí)候存在的。Wedon’tknowwhentheworldcameintobeing.2.Whenscientistsinspectedthebones,theyweresurprisedtofindthatthesedinosaurscouldnotonlyrunliketheothersbutalsoclimbtrees.

本句中的tofindthat...是不定式作原因狀語。不定式用來表原因時(shí)，常修飾表示情感、心理狀態(tài)、性格等的形容詞，如：happy，glad，lucky，fortunate，surprised，angry，anxious，cruel，clever，frightened，shocked，sorry，eager，proud，disappointed，foolish，impatient，unwise，naughty等。如：Weweresurprised

toseehim.我們真想不到會(huì)見到他。Weareproud

tobeyoungpeopleofnewChina.作為新中國的青年，我們感到很驕傲。Youwerefoolish

toactlikethat.你那樣做很愚蠢。3.Somescientiststhinkitcameafteranunexpectedincidentwhenahugerockfromspacehittheearthandputtoomuchdustintotheair.

本句中when引導(dǎo)定語從句，其先行詞為incident。關(guān)系副詞when的先行詞一般是表時(shí)間的名詞，如:HecamelastnightwhenIwasout.

但有時(shí)并不直接是表時(shí)間的名詞，如：In1921EinsteinwontheNobelPrize,andwashonoredinGermanyuntiltheriseofNazismwhenhewasdrivenfromGermanybecausehewasaJew.1921年愛因斯坦獲得了諾貝爾獎(jiǎng)，他在德國很受尊敬。納粹上臺后由于他是猶太人而被趕出了德國。4.AccordingtoaUNreport,….
