:1.No permission ————has for anybodyto enter the building.(N M ET1988)

A.been given B.givenC.to give D.be giving

A。析语境可知,该空表示被给,应用被动语态,has后面应接been done。

2.U ntil now,his hom ework has not————finished.

A.being B.be C.been D.to be

C。语境逻辑制约家庭作业是被完成的,因此该空应用被动语态,has后面应使用been done的形式。点评:现在完成时被动语态结构为has/have been done,使用has been done时主语为单数,使用have been done时主语为复数。解题时应首先分析语境逻辑确定现在完成时被动语态,然后对照其结构公式确定答案。

3.The window————.Y ou need notwash it again.

A.is w ashed B.was washedC.has been washed D.will be washed析:

C。该句强调窗户已被清洗。

4.It seem that dinner ____for a long time.

A.is cooked B.has been cooked C.was cooked D had been cooked

B.表示晚饭已经准备好了。对现在有影响。

5。When my article ____.I'll come to see you .

A.is finished B is being finished C has been finished D will be finished

C 现在完成时被动语态代替将来完成时被动语态。

1. I'm sorry, sir. Your recorder isn't ready yet. It______in the factory.

A. is being repaired B. is repaired

C. has been repaired

D. hasn't repaired

本题并没有明确的时间状语，但从上文的意思看，“修理”这个动作正在进行；it指代上文提到的录音机，它和repair之间存在被动关系。因此应该使用现在进行时的被动语态。B、C两项是被动语态，但时态不对，因此，本题正确答案是A。

2. Some measures______to protect wildlife resources.

A. are taking B. are taken

C. are being taken

D. being taken

解此题时首先要注意到词组take measures to do sth.，由于题干中把宾语measures提前，应该使用被动语态；句子的意思是“正在采取一些措施去保护野生资源”。在表达现在进行时的被动语态的结构中，选项A、B、D均不完整，正确答案应是C。

3. —Have you moved into the new house?

—Not yet. The rooms______.

A. are being painted

B. are painting

C. are painted

D. are being painting

通过题干情景，我们不难看出，由于正在粉刷，因此还不能搬进新房子。分析选项，B项语态不对；C项时态不对；D项结构错误，所以正确答案应该是A。

4. A new building______at the other side of the street. Work started last year and the building is expected to open next year.

A. is built

B. is being built

C. has built

D. will be built

题干的后半部分告诉我们：“去年开工，预计明年竣工。”由此可知，大楼正在建设中，所以选项A、C、D时态均不对。正确答案应该是B。

5. It is well-known to us that a lot of rivers______by the factories.

A. are polluting

B. have been polluting

C. are being polluting

D. are being polluted

题干的意思是：“众所周知，许多河流正在被工厂污染。”说明了目前河流正在被污染的严重状况。A、B两项语态不对；C项结构错误，正确答案是D。
