据专家权威分析，试题“按照要求进行句型转换。1. My mother made this skirt last mon..”主要考查你对 被动语态，主谓一致 等考点的理解。关于这些考点的“档案”如下：
被动语态的构成: 被动语态的基本结构： 主语+be +过去分词(+by+动作的发出者） ① 一般现在时：am/is/are+过去分词 如：Trees are planted every year. ② 现在进行时 am/is/are+ being +过去分词 如：The road is being repaired. ③ 现在完成时 have/has + been +过去分词 如：The work has been finished. ④ 一般过去时 was/were + 过去分词 如：The story was told by him. Many birds were killed last year. ⑤过去进行时 was/were+ being + 过去分词 如： The new house was being painted when I got home. ⑥过去完成时 had +been+ 过去分词 如： He told me that the work had been finished. ⑦一般将来时 will +be + 过去分词 如：The problem will be discussed tomorrow. ⑧ 过去将来时 would/should +be +过去分词 如： He said that the Christmas tree would be put up soon. ⑨情态动词的被动语态 情态动词+ be +过去分词 如：The problem must be solved soon. Children should be taught to love animals.
被动语态使用注意: 1. 不及物动词无被动语态。 如：happen, break down, come out...... What will happen in 100 years. The dinosaurs disappeared about 65 million years ago. 2. 有些动词用主动形式表示被动意义。 如： write, sell, ride..... This pen writes well. This new book sells well. 3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带“to”，但变为被动语态时，须加上“to”。 例：make somebody do something→somebody+ be +made to do something see somebody do something→somebody +be +seen to do something A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 4. 如果是接双宾语的动词改为被动语态时，直接宾语（物）作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。 He gave me a book.→A book was given to me by him. He showed me a ticket.→A ticket was shown to me by him. My father bought me a new bike. →A new bike was bought for me by my father. 5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。 We can’t laugh at him. →He can’t be laughed at by us. He listens to the radio every day. →The radio is listened to by him every day. The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse. 构成be+done.
不用于被动语态的情形： ①不及物动词没有被动语态 这类动词有take place, happen, come about, break out, appear, disappear, last, arise等。 例如：A fire broke out during the night. ②某些静态动词不用于被动语态 这类动词有have, lack, fit, hold, suit, resemble等。 例如：My shoes do not fit me. ③宾语为相互代词和反身代词时不用于被动语态 例如：We should help each other.
关于主动形式表示被动意义: ①系动词（如look, sound, smell, feel, taste, prove等）要用主动表被动，因为系动词为不及物动词，它们没有被动语态形式。 例如：The building looks very beautiful. ②当open, close, shut, lock, move, read, wash, clean, cook, cut, wear, carry 等用作不及物动词且表示主语的某种属性时，通常用主动形式表示被动意义。 例如：The book sells well. ③有的动词本身含有被动意味，通常用主动形式来表示被动含义。 例如：Her eyes filled with tears. ④不定式to blame, to let用作表语时，通常要用主动表被动。 例如：Who is to blame? ⑤某些“be+形容词+to do”结构中的不定式通常要用主动形式表示被动意义。 例如：The book is difficult to understand. ⑥不定式用于某些动词（如have, have got, get, want, need等）的宾语后作定语时，如果不定式的逻辑主语就是句子的主语，通常用主动形式表示被动意义。 例如：Do you have time to help us? ⑦在too...to do sth.和...enough to do sth. 这两个结构中，若主语与其后不定式为to do sth.被动关系，则该不定式通常用主动形式表示被动意义（有时也可直接用 被动式）。 例如：The writing is too faint to read. ⑧be worth后的动名词要用主动表被动。 例如：This movie is worth seeing. ⑨在need, want, require等少数表示“需要”的动词后的动名词用主动形式表示被动意义。 例如：The house needs cleaning.
表示“据说”的三类被动句型: ①It is said that...句式 例如：It is said that thirteen is an unlucky number. ②There is said that...句式 例如：There is said to be plenty of oil off our coast. ③sb./sth.is said that...句式 例如：Mr. Brown is said to have died of liver cancer.
主谓一致原则: 1、语法上的一致 所谓语法一致原则，即主语和谓语的语法形式在人称和数上取得一致。 谓语的单、复数形式依据主语的单、复数形式而定：主语为复数，谓语动词用复数；主语为单数或者是不可数名词，谓语动词用单数。 China belongs to the Third World. 中国属于第三世界。 We are sure he will come. 我们肯定他会来。 使用语法一致的情况 （1）当主语是and，both…and连接的并列结构 如果主语指的是两个或两个以上的人或物，则谓语动词用复数。 My mother and I have seen the film. 我妈妈和我已看过这部电影。 Both rice and wheat are grown in this part of China. 在中国的这个地方既种稻子又种小麦。 注意：由and连接的并列主语前面分别有each，every，no修饰时，其谓语动词用单数形式。 Every boy and every girl has to receive education in our country. 在我国每一个男女孩子都得受教育。 No student and no teacher was invited to the party. 师生没有被邀请参加晚会。 （2）主语后面接说明主语的修饰语 主语后面接说明主语的修饰语如： with，along with，together with，as well as，like，rather than，but，except，besides，including，in addition to， 谓语动词不受修饰成分的影响，仍保持同主语一致的关系。 The teacher with two students was at the meeting. 那位老师和两个学生参加了会议。 The girl as well as the boys has learned to drive a car. 这个姑娘和男孩子一道，也学会了开汽车。 A library with five thousand books is offered to the nation as a gift.一个有5000册书的图书馆作为礼物赠送给了国家。 E-mail, as well as telephones, is playing an important part in daily communication.电邮和电话在日常的通信中起着很重要的作用。 Nobody but Jane knows the secret.只有简知道这个秘密。 All but one were here just now. 刚才除了一个人外都来了。 （3）非谓语动词或从句作主语 非谓语动词 (动词的-ing形式、不定式)或从句作主语时，谓语一般用单数形式。 When and where to build the new factory is not decided yet.什么时候在什么地方建新工厂还没定下来。 Checking information is very important. 核实事实是非常重要的。 To learn foreign languages is not easy. 学习外语并非易事。 When we will hold the meeting is not decided yet. 我们何时开会尚未决定。 注意：当what引导主语从句或由 and连接两个动词不定式或动名词作主语时，谓语动词的数应根据意义一致的原则来决定。 What we need here is money．我们这里需要的是资金。 What we need here are workers．我们这里需要的是工人。 Lying and stealing are immoral．说谎与偷窃是不道德的。 （4）each和复合不定代词作主语 each和some/any/no//every十body/one/thing构成的复合不定代词： anyone、anybody、anything、everyone、everybody、everything、someone、somebody、something、no one、nobody、nothing、each、the other作主语，谓语动词用单数。 Each is worse than the one before. 一个比一个差。 Nobody knows the answer. 没有一个人知道这答案。 Someone wants to see you. 有人想见你。 Is there anything in the box?箱子里有什么东西吗?

"表里不一"现象： 主谓一致中的"表里不一"现象 和主语必须在人称和数上保持一致，最基本的原则是：单数主语用单数动词，复数主语用复数动词.但在实际使用当中情况比较复杂，现在学生常犯的主谓一致错误归纳整理如下 1,"more than one +名词"作主语时，谓语动词常用单数.例如： More than one teacher gets the flowers. 不止一个教师得到了花. 2,"many a +名词"作主语时，从意义上看是复数，但谓语动词常用单数.例如： Many a student has been sent to plant trees. 很多学生被派去植树. 3,"half of,the rest of,most of,all of及百分数或分数+of 等后接名词"作主语时，谓语动词形式根据of后的名词而定.例如： Three fourths of the surface of the earth is covered with water.地球表面四分之三为水所覆盖. 4,all指人时，动词用复数；all指物时，动词用单数.例如： "All are present and all is going well." 所有人全部到场了，一切进展顺利 5,what引导的主语从句，谓语动词可视表语而定：表语是单数名词时，动词用单数，相反，则用复数.例如： What they want to get are a number of good books.他们想得到的是大量的好书. 6,and连接的两个单数名词前若用each,every,no修饰，该名词短语作主语时，谓语动词用单数形式.例如： No book and no pen is found in the schoolbag.书包里没有书和钢笔. 7,当主语后面有as well as,with,along with,together with,but,like,rather than,except，逗号加and连接几个名字等引导的短语时，谓语动词要与最前面的主语保持一致.例如： My father as well as his workmates has been to Beijing. 我父亲和他的同事曾去过北京. 8,each作主语的同位语时，谓语动词由主语来决定，与each无关.例如： They each have a bike. 他们每人有一辆自行车. 9,动词不定式，动词-ing形式短语作主语时，谓语动词常用单数.例如： Going out for a walk after supper is a good habit.晚饭后出去散步是一个好习惯. 10,the following作主语时，谓语动词的数与后面名词的数保持一致.例如： The following are good examples下面是一些好例子. 11,以-ics结尾的学科名词，如politics,physics,mathematics等作主语时，谓语动词用单数.以-s结尾的名词news,works,plastics等同属此类.例如： Politics is now taught in all schools. 现在各学校都开设政治课. 当以-ics结尾的学科名词表示"学科"以外的意义时，用作复数，如：mathematics（运算能力）politics(政治观点）economics（经济意义）等 12,有些用来表示由两个对应部分组成一体的名词复数（trousers,glasses,shoes.shorts.scissors.scales等）作主语时，前面若有"一条","一副","一把"之类的单位词，动词用单数；若没有单位词或单位词是复数，则谓语动词用复数.例如： The shoes are all right. 这些鞋子都很合适. 还有一些以-s结尾的名词通常用复数：arms（武器）.clothes.contents.minites（记录）.remains（遗体）.thanks等 13,"one and a half +名词"作主语时，谓语动词要用复数.例如： One and a half apples are left on the table. 桌子上有一个半苹果. 14,"One or two more +复数名词"作主语时，谓语动词用复数.例如： One or two persons are sent there to help them do the work. 要派一两个人到那儿去给他们帮忙. 15,"one of+复数名词+ 定语从句"结构中，定语从句的谓语动词要用复数；而在"the only one of +复数名词+定语从句"的结构中，"the one of + 复数名词+定语从句"定语从句的谓语动词要用单数.例如： He is one of the students who get there on time.他是准时到达那里的学生之一. 16,表示时间，距离，金钱等的复数名词作主语表达一个整体概念时，谓语动词常用单数，但若强调数量，谓语动词可用复数.例如： One million dollars is a lot of money. 一百万美元是一大笔钱.
以-s结尾的名词作主语的主谓一致: 英语可数名词的规则复数形式是在词尾加-s或-es，但是有一些以-s结尾的名词并不是可数名词。 它们用法多样，造成了实际使用上的困难，以下详述了以-s结尾的名词作主语的主谓一致问题。 （一）以-s结尾的疾病名称作主语的主谓一致问题 （二）以-s结尾的游戏名称作主语的主谓一致问题 （三）以-s结尾的地理名称作主语的主谓一致问题 （四）以-ics结尾的学科名称作主语的主谓一致问题 （五）其它以-s结尾的名词的主谓一致问题 集合名词的主谓一致原则: 集合名词作主语时，主谓一致关系是一个较为复杂的问题.对此类问题我们可以从"数"的角度分为四类. 1)单数—复数型.凡是有复数词尾变化形式的集合名词都属于此类。如： a class—classes; a family—families; a government—governments; an army—armies; a people—peoples; a group—groups; a crowd—crowds; a crew—crews等。 这类集合名词强调的是整体性，即当作一个整体或多个整体来看待。属于这类集合名词的单数作主语时，谓语动词用单数； 复数形式作主语时，谓语动词用复数。 【例如】 A big crowd often gathers on the square every morning. 每个上午 一大群人经常聚集在广场上 The government has decided to pass the bill. 政府已决定通过这一法案 There are huge crowds in the streets on Sunday. 星期天有大群大群的人在街上。 There are many English-speaking peoples in the world. 在世界上有许多讲英语的人 但应注意，这类集合名词的单数形式有时表示复数概念，所以这些集合名词的单数形式也可归为"单复同形型"中. 2)单数型.这类集合名词表示的是人或事物的整体，即把这类人或事物的全部包括在内，所以只有单数形式.如作主语，谓语动词常用单数。 这类名词常见的有：humanity,mankind,proletariat等. 【例如】The proletariat is the greatest class in the history of mankind. In the fields of production and scientific experiment,mankind makes constant progress. 3)复数型.这类集合名词在形式和内容上是相互矛盾的，就是说它们只有单数形式，但表达的都是复数概念。它强调的是集体中的个体性.这类名词有：police,cattle,faculty,flock,machinery,vermin,personnel等.它们作主语时，谓语动词要用复数. 【例如】The police have caught the murder. Our personnel are very highly trained. The vermin are very dangerous. 4)单复同形型.这类集合名词的单数形式既可表示单数也可表示复数.作主语时，用单数动词或复数动词均可，有时意义区别不大. 【例如】The school teaching staff are (is) excellent. The public is (are) requested not to litter in the park. The teaching profession claim(s) to be badly paid. 这类集合名词常见的有：class,family,team,crew,board,herd,committee,party,jury,enemy,audience等. 根据说话人的心理意向若把这个集合名词所代表的人或事物看作一个整体，就认为是单数，用单数动词； 若把它所代表的人或事物看作若干个个体的话，就认为其为复数，用复数动词。 试比较：The football team is playing well. 那个足球队打得非常漂亮. The football team are shavings bath and are then coming back here for tea. 足球队员们正在洗澡，然后来这里吃茶点。 The family is a very happy one.那个家庭是一个非常幸福的家庭。 That family are very pleased about the news of William's success. 全家人对威廉的成功都感到很高兴。
