　　【答案】

　　1. C 含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài)，在情態(tài)動(dòng)詞的后面用“be +過(guò)去分詞”。

　　2. D 含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài)，在情態(tài)動(dòng)詞must的后面用“be +kept off”表示

　　被動(dòng)。注意off不能丟掉。

　　3. B 從句子可以判斷用“be+過(guò)去分詞(chosen)”表示“被選為”。

　　4. A 主語(yǔ)不是動(dòng)作的執(zhí)行者，所以用被動(dòng)語(yǔ)態(tài)。

　　5. B 句子的主語(yǔ)是lights和后面的動(dòng)詞turn on/off是被動(dòng)關(guān)系，所以用被動(dòng)語(yǔ)態(tài)。

　　從句意判斷用turn off(關(guān)燈)。

　　6. D 從句子的主語(yǔ)和謂語(yǔ)的關(guān)系判斷是被動(dòng)關(guān)系，用被動(dòng)語(yǔ)態(tài)。從句子的時(shí)間狀語(yǔ)

　　看是一般過(guò)去時(shí)，所以用was built。

　　7. C unless“除非”，和if not是同義詞，所以前面用被動(dòng)語(yǔ)態(tài)的否定形式。

　　8. A 含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài)，從對(duì)話后面的句子判斷前面的句子是否定句。

　　9. C 主語(yǔ)roads與后面的謂語(yǔ)build之間是被動(dòng)關(guān)系，要用被動(dòng)語(yǔ)態(tài)。含有情態(tài)動(dòng)詞

　　的被動(dòng)語(yǔ)態(tài)是在情態(tài)動(dòng)詞的后面用“be+過(guò)去分詞”構(gòu)成。

　　10. B 從“垃圾不能扔到河里”可以判斷是用mustn't表示“不允許，禁止”。同時(shí)

　　本句是被動(dòng)語(yǔ)態(tài)，所以用mustn't be thrown。
