第二部分 被动语态
一、被动语态的用法：
1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词 Our classroom is cleaned everyday. I am asked to study hard. Knives are used for cutting things.
2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词 A new shop was built last year. Dinosaur eggs were laid long long ago.
3. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词 A new hospital will be built in our city. Many more trees will be planted next year.
4. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词 Uncle Wang is mending my bike now.→ My bike is being repaired by Tom now. They are planting trees over there. → Trees are being planted over there by them.
1. -Lizzy, you ________ on the phone.
-I’m coming. Thanks.
A. want B. are wanting
C. are wanted D. have wanted
解： C。这组对话的意思是：“利齐，有人打电话找你。”“我就来，谢谢！” 该题测试动词的被动语态。接电话者或电话里要找的人作主语时，要用被动语态。
2.-What’s wrong with that boy?
-He ________ by a car yesterday.
A. is hit B. hit
C.was hit D. Hits
解： C。此题易误选为B。这是忽略语境和草率做题造成的。许多同学一看到yesterday就马上想到用过去时。而忽略了by a car这个短语。正确答案为C。
3. Oh, the milk ________ strange-do you think it’s OK to drink?
A. is tasted B. is tasting
C. tastes D. tasted
解： C此题易误选为A或B。taste是连系动词，它没有现在进行时或被动语态。正确答案为C。
4. These books should ________ to the library on time.
A. send B. be returned
C. give back D. be got back
解： B。考查含有情态动词的被动语态用法。其结构为“情态动词 + be + 过去分词”。
5. Could you tell me which ________ best among the books on sale?
A. is sold B. sells
C. are writtenD. Writes
解： B。“请告诉我展销的书中哪一种畅销，好吗？”sell作“销售”解，是不及物动词，不用被动语态。此题易误选A。又如Butter sells very dear. 奶油卖得很贵。
