初二英语第七单元知识点及练习语法详解：被动语态英语中的语态－主动语态和被动语态⒈英语动词有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
如：①They built a new bridge over the river. (主动)→A new bridge was built over the river by them. (被动)②Many people speak English. (主动)→English is spoken by many people. (被动)⒉汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用“助动词be＋及物动词的过去分词构成”，即“be＋p.p.”，其中助动词be有人称、数和时态的变化。
被动语态的基本用法⒈当句子的主语是动作的执行者时，谓语的形式是主动语态。
当句子的主语是动作的承受者时，谓语要用被动语态。
被动语态由助动词be＋过去分词构成，时态通过动词be表现出来。
⒉什么时候使用被动语态⑴不知道或没有必要说明动作的执行者是谁。
①Some windows were broken last night.②This book was published (出版) in 2005.注意：第②句＝This book came out in 2005. come out 是不及物动词短语，不能用于被动语态。
⑵只强调动作的承受者，而不强调动作的执行者。
①Educational CD-ROMs are sold in many countries.②Rice was first grown in China.③English is learned all over the world.注意：不及物动词或不及物动词短语无被动语态，如：appear, happen, take place被动语态的基本结构⒈动作的承受者＋be＋过去分词＋其他＋by＋动作的执行者。
简写为“承受者＋be＋过去分词＋其他＋by＋动作的执行者”。
⒉主动语态变为被动语态的步骤：确定主动语态的时态，它决定着被动语态中的助动词be。
→找出主动语态的主、谓、宾。
→按照上述句式改写：承受者+be+过去分词+其他＋by＋执行者⒊常用的被动语态结构⒋主动改为被动语态的例子：主动语态基本结构为主、谓、宾。
⑴His brother washes dishes every day.→Dishes are washed every day by his brother.主(执行者) 谓宾(承受者) 其他⑵Peter will clean the room tomorrow.→The room will be cleaned tomorrow by Peter.⑶He must look after the little boy.→The little boy must be looked after by him.⑷The students are watching a charity show.→A charity show is being watched by the students.特殊情况的被动语态简单句五种基本形式中的其中两种变为被动语态时十分重要：⒈主谓＋双宾：这类短语含有介词to或for。
如：give, send, show, buy, make…⑴give sb sth＝give sth to sb，buy sb sth＝buy sth for sb主动语态Amy gave me some nicestickers.Amy gave some nice stickers to me.被动语态：I was given some nice stickers by Amy.或Some nice stickers were given to me by Amy.⑵主动：A fairy gave the princess a magic wand.＝A fairy gave a magic wand to Princess Laura. 被动：The princess was given a magic wand by a fairy.或A magic wand was given to the princess.总结含有双宾语的动词短语变为被动语态的规则：可以把任何一个宾语作为被动语态的主语；如果把直接宾语(即物体)作为主语，动词和直接宾语之间要添加相应的介词to或for。
主动语态中无论使用give sb sth 还是give sth to sb，一律按照上述句子改写，即：give sb sth 或give sth to sb →sb be given sth或sth be given to sb，这类含有介词to或for的短语见下表⒉主谓宾＋省略to的不定式(即宾补)：使役动词变为被动语态时原来省略的to一定要加上。
同)⑵hear sb do sth→sb be he常见短语⑴make sb do sth→sb be made to do sth (主动语态不含to，被动语态必须带to。
（下ard to do sth⑶see sb do sth→sb be seen to do sth⑷have sb do sth →sb be had to do sth注意特殊例子：let sb do sth →sb be let do sth (主动语态和被动语态都不含to。
)e.g. He made the workers work 12 hours a day. The workers were made to work 12 hours a day.主动形式表示被动意义：有些不及物动词(其主语大都指物)的主动语态可以表示被动意义。
⒈某些连系动词，feel, taste, smell, sound, prove等。
①The coffee smells delicious. ②The story proved quite false.⒉某些可与well, easily, quickly等副词连用的不及物动词。
①This kind of bikes sells well. ②Thisind of rice cooks more quickly than that kind.⒊某些可用于“主＋谓＋主补”结构中的不及物动词。
e.g. The bag broke open.⒋动名词在be worth doing句型中的主动形式表示被动含义。
①His novels are so well worth reading that I want one.②These stamps are worth collecting.⒌动名词在need, want, require等动词后，主动形式表示被动含义。
need doing＝need to be done①The problem requires dealing with immediately. ②Her bike needed repairing.⒍动词不定式的主动形式在too…to…句型中表示被动含义。
The box is too heavy to carry.⒎有些形容词后的动词不定式有被动含义。
这些形容词有easy, difficult, heavy, nice, good, pleasant, important, useful, dangerous等。
①Bad habits are easy to contract. ②English is difficult to learn.二知识点ternational : adj. 国际的an international meeting / international languages2. pocket money 零花钱3. be used to doing sth. 习惯于做某事He is used to getting up early every day.Used to do sth 过去常常做某事He used to go o ut for a walk after supper, but now he isn’t.Be used to do sth. / be used for doing sth. 被用来做--- Knives are used to cut things.4. further :adv. / adj. too weak to walk any further / further studyFarther: adv. He jumped farther than Jack5. interviewer ：采访者interview v. / n.6. blindness ：n. 失明/ blind : adj the blind7. affect: v. （influence, effect）affect 是及物动词，表示“影响，（病）侵袭”，暗示产生的影响如此强烈，以至能引起反应，也可表示思想感情受外界事物的影响而感动。
The disease affected his mind very much.The film so affected her that she cried.effect 表示“影响”时，是名词，不能误用为动词，常用在have an effect on sb.influence 通常指对某人的间接影响，多指行为方面的影响The medicine has little effect on the old man.What we read influences our thinking.8. medical adj. 医学的，医疗的----medicine n.9. treatment n. ----treat v. 治疗，对待10. volunteer n. 志愿者，义务工作者---- voluntary adj. 志愿的，自愿的11. operation: n. 手术perform / do an operation on sb operate: v. operate on sb12. patient: n. 病人---- adj. 耐心的13. afford: v.常与can, could, be able to连用)买得起;有足够的...(去做...)[+to-v]They did not consider whether they could afford the time or not.他们没有考虑是否抽得出时间。
