1. ④处为现在完成时的主动语态形式；
2. ①②③⑤⑥处为现在完成时的被动语态形式。
——运用“形式—意义—使用”相结合的三维动态语法观
　　现在完成时的被动语态表示动作已经完成，强调对现在造成的影
响或结果，而且主语和谓语动词之间是逻辑上的被动关系。
一、现在完成时的被动语态的构成及用法
【先感悟】

has been celebrated for about 40 years！
②（教材典句）Much has been written about the wonders of the World
Wide Web.
③To Tom’s disappointment， his novel has not been published.
④Have all of the stadiums for the games been finished？
⑤Excuse me， Andy， why has the plan for our designs been changed
again？
【会发现】

形式；句③是完成时的否定形式；句④是 形式；
句⑤是 形式。
肯
定　
一般疑问句　
特殊疑问句　
【善归纳】
1. 现在完成时的被动语态的构成
肯定式 主语＋have/has been done ...
否定式 主语＋have/has not been done ...
一般疑问式 Have/Has＋主语＋been done ...？
特殊疑问式 疑问词＋have/has＋主语＋been done ...？
2. 现在完成时的被动语态的用法：
（1）现在完成时的被动语态，强调过去的动作对现在造成的影响或
结果，通常与already， yet， just， never， ever， so far， recently等
副词连用。
（2）表示一个被动的动作或状态开始于过去，持续到现在，并可能
持续下去，常与for或since引导的时间状语连用，或用于How
long ...？句型中。
（3）用在时间或条件状语从句中，表示将来某时已完成的动作，即
用现在完成时的被动语态代替将来完成时的被动语态。
名师点津
常与现在完成时连用的时间状语：
already， lately/recently， since then， ever since， for a long time， so
far， by now， in recent years， in/during/over the past/last few years，
over the years， up to now等。
【运用练】　单句语法填空
①At the foot of Mount Tai you can also visit the temples that
（protect） for over 3，000 years.
②In the past ten years， great achievements
（make） in our economy， life， science， and so on.
③So far， the English Reading Club of our school
（establish） for more than one year.
④In recent years， more and more food （waste）
by us students， which aroused public concern.
⑤You shouldn’t go out before your homework
（finish）.
have been
protected　
have been made　
has been
established　
has been wasted　
has been finished　
二、现在完成时的被动语态的注意事项
【先感悟】
①Some artists have been looked down upon in the past few years.
②He has been given a chance to work abroad recently.
③A chance to work abroad has been given to him recently.
④He has been seen to enter the building.
【会发现】
（1）句①中的look down upon是动词短语，构成被动语态时
；
（2）句②③中分别是 宾语和 宾语作主语构成的被
动语态；
（3）句④中感官动词的宾语补足语为省去to的动词不定式时，在变为
被动语态后，不定式前要 。
不可分
开　
间接　
直接　
加上to　
【善归纳】
1. 只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被
动语态的主语。
2. 带有双宾语的动词，如give， send， bring， take， teach， show，
tell， buy， lend， promise等，变为被动语态时，一般将间接宾语变
为被动语态的主语，若将直接宾语变为被动语态的主语时，间接宾语
前面要用相应的介词。
3. 非延续性动词，如borrow， finish， begin， start， buy， marry，
open， join等构成的现在完成时的被动语态不能与表示一段时间的状
语连用。若要表达相应的意思，则要改换动词或时态。
但这类动词的否定式可表示动作的持续过程，具有延续性，因而可与
since或for引导的时间段连用。
【运用练】　单句语法填空/把下列句子变为被动语态
①Many problems （find） with our new computer
over the last few years.
②Some texts and pictures （send） to George’s
friend’s cell phone ever since.
③The traditional skill of making paper by hand
（pass） down for hundreds of years.
④We have reserved rooms for the honored guests in the nearby
neighbourhood.

neighbourhood.
⑤Their teacher has given them many chances to practice what they have
learned in class.
→ to practice what they have
learned in class （by their teacher）.
→ to practice what they have
learned in class （by their teacher）.
Rooms have been reserved for　
Many chances have been given to them　
They have been given many chances

络的人的数量在上升，但同时他们也会失去很多机会。
16. the　考查冠词。固定短语the number of ...表示“……的数
量”。故填the。
17. are known　考查时态、语态和主谓一致。根据主句时态可知，从
句也应用一般现在时，表示“作为……而有名”，用be known as，所
以用被动结构，从句主语who指代的是先行词These people，所以be动
词用复数形式are。故填are known。
18. connected　考查形容词。设空处在系动词getting后，所以应该用
形容词作表语。故填connected。
19. from　考查介词。介词短语from ...to ...表示“从……
到……”。故填from。
20. skills　考查名词复数。设空处应为名词作介词in的宾语，表示泛
指，所以用复数形式。故填skills。
21. is　考查时态和主谓一致。设空处在句中作谓语，叙述客观事
实，应用一般现在时，主语是high speed net，所以谓语用第三人称单
数形式。故填is。
22. to take　考查非谓语动词。根据句子结构和意思可知，此处为动
词短语would like to do sth，表示“想要做某事”。故填to take。
23. increasing　考查非谓语动词。分析句子结构可知，此处为 “with
＋宾语＋宾语补足语”结构，设空处作宾语补足语，和宾语之间是逻
辑上的主谓关系，应用动词-ing形式。故填increasing。
24. who　考查定语从句。设空处引导定语从句，先行词是those，在
从句中作主语，指人。故填who。
25. especially　考查副词。设空处应用副词作状语，修饰后面的介词
短语in their work。故填especially。
