2 What lessns can yu learn frm the cllapse f Maya civilizatin? Hw can this infrmatin help the develpment f tday’s sciety?

Step 6: Language appreciatin
1. The fact that Maya sciety was technlgically primitive makes its achievements all the mre incredible and mysterius.
[句式分析] “that Maya sciety was technlgically primitive”是 that 引導(dǎo)的同位語從句，解釋說明主名詞the fact的具體內(nèi)容，引導(dǎo)詞that只起引導(dǎo)性作用，不在從句中充當(dāng)任何成分。
[嘗試翻譯] 事實上，瑪雅社會在技術(shù)上是原始的，這使得它的成就更加難以置信和神秘。
2. This is likely t have led t a series f drught, each lasting fr a cuple f years.
[句式分析] “each lasting fr a cuple f years”是由“代詞+ 現(xiàn)在分詞”構(gòu)成的獨立主格結(jié)構(gòu)。 其中動詞last 與邏輯主語each 構(gòu)成主動語態(tài)關(guān)系，故使用現(xiàn)在分詞。
[嘗試翻譯] 這可能導(dǎo)致了一系列的旱災(zāi)，每一次旱災(zāi)持續(xù)幾年時間。
3. Meanwhile, the rise and fall f this civilizatin must als leaves us thinking abut ur wn past, present and future.
[句式分析] “l(fā)eave + 賓語+ 賓語補足語”表示“使處于某種狀態(tài)”，賓語補足語可以是現(xiàn)在分詞、過去分詞、不定式、形容詞、名詞或小品詞（n/ff; up/ dwn; away/ in/ut）。
[嘗試翻譯]與此同時，這種文明的興衰也必然讓我們思考自己的過去、現(xiàn)在以及未來。
