　　看看答案吧：

　　1.C 此句譯為我將記下你的姓名和地址，以防萬一需要你作證,這是被動語態(tài)的基本用法,我或別的什么人需要你作證人,但沒必要指出來,因?yàn)檫@里強(qiáng)調(diào)的是動作的承受者,所以用將來時(shí)的被動語態(tài).

　　2.B 當(dāng)不定式作表語(或賓補(bǔ))形容詞的狀語,又與句中的主語(或賓語)有邏輯上的動賓關(guān)系時(shí),雖然不定式有被動意義,但只能用主動形式.eg:Some books are interesting to read ,but boring to learn有些書讀起來很有趣,但學(xué)起來很枯燥.

　　3.B 此句譯為中國人糧食極其匱乏，經(jīng)濟(jì)拮據(jù)，生活不安逸，住房又緊缺的日子已經(jīng)一去不復(fù)返 ,如果過去分詞是不及物動詞,這個動詞已經(jīng)是形容詞化了的分詞,則為系表結(jié)構(gòu),這里gone提前,用的倒裝結(jié)構(gòu).
