一. 名詞性從句的類型以及語用功能
單元語法 復(fù)習(xí)名詞性從句
1. 連詞that：本身無意義。引導(dǎo)單一的賓語從句時(shí)that?？墒÷?，但引導(dǎo)主語從句、表語從句、同位語從句時(shí)that通常不被省略。2. whether,if ：本身有意義"是否"，表從句內(nèi)容不確定性；as if =as thugh：表示"好像/似乎"，以上在從句中均不充當(dāng)任何成分。 3. 連接代詞10個(gè): what/whatever, wh/whever, whm/whmever, whse/whsever, which/whichever;4. 連接副詞8個(gè):when/whenever, where/wherever, hw/hwever, why,because.

In such a case, I will insist n ___________ I bebieve is ture. 7. ____________ breaks the rules will be punished fr sure.
1. 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(dú)立主格 結(jié)構(gòu)。 其中動(dòng)詞last 與邏輯主語each 構(gòu)成 主動(dòng) 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(shí)間。
1. S many students _________ (be) absent, the meeting had t be put ff.2. The by lay n his back, his hands ____________ (crss) under his head.3.

2. 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(bǔ)足語”表示“ 使處于某種狀態(tài) ”，賓語補(bǔ)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(shí)，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。
