(3)The artist was sure he would be chosen　(choose), but when he presented his masterpiece to the emperor's chief minister, the old man laughed. (4)—The machine is working again! —Yes, it broke down yesterday, but it has been fixed　(fix). (5)My washing machine is being repaired　(repair) this week, so I have to wash my clothes by hand. 二、主动形式表示被动意义的情况 1．谓语动词的主动表示被动 (1)连系动词(如look，sound，smell，feel，taste，remain，prove等)后接表语时，一般用主动形式表示被动意义。 ◆Your advice sounds practical. 你的建议听起来是可行的。 ◆Whether we can have a holiday next week remains unknown. 我们还不知道下周能否放假。 (2)当open，close，shut，lock，move，read，wash，clean，cook，sell，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。 ◆That kind of shirt cleans easily. 那种衬衫容易洗干净。 ◆This kind of wool shirt feels soft and sells well. 这种羊毛衫摸起来很软，卖得很好。 2．非谓语动词的主动表被动 (1)在 want，need，require等少数表示“需要”的动词后用动词­ing形式的主动形式表示被动意义，其含义相当于动词不定式的被动形式。 ◆The house needs cleaning(＝to be cleaned). 这所房子需要打扫。 ◆This wall requires repairing(＝to be repaired). 这面墙需要修理。 (2)某些作表语的形容词(如easy, hard, difficult等)后，用不定式的主动形式表示被动意义。 ◆He is easy to get along with.很好相处。 ◆This question is easy to answer.这个问题容易回答。 [即时演练2]——用所给动词的适当形式填空 (1)I need to go　(go) home now, because my coat need mending　(mend). (2)After the concert, Naomi told the family that Steve's music was beautiful and professional.It needed sharing/to be shared　(share) in public. (3)The number of medical schools reached 18 in the early 1990s and has remained (remain)around that level ever since. (4)The bag was very heavy to carry　(carry), so the boy had to ask his father to help. 三、使用被动语态时应注意的问题 1．不及物动词(短语)无被动语态。常见的不能用于被动语态的动词(短语)：appear，belong，disappear，come true，happen/take place/occur，remain(剩余)，last(持续)，break out，come out(出版)，come up(提出)，lose heart，run out(用完)。 2．在主动语态里，动词see，make，hear，watch，notice等后面作宾语补足语的动词不定式不带to，但变为被动语态时，必须加上to。 ◆They made him go there alone. →He was made to go there alone by them. 他们让他独自去那里。 3．接双宾语的动词变被动语态。有些动词在主动语态中常接双宾语，即直接宾语(一般指物)和间接宾语(一般指人)。在变为被动语态时，如果间接宾语被提前作主语，那么直接宾语保留不变；如果直接宾语被提前作主语，那么间接宾语前一般要加上相应的介词to或for。 ◆We gave him the letter.＝He was given the letter by us.＝The letter was given to him by us. 我们把那封信给他了。 4．将含有“动词＋介词/副词”类动词短语(如look after，put on)的主动句变为被动句时，原动词短语中的介词或副词应保留下来。 ◆She often looks after the old. →The old are often looked after by her. 她经常照看老人。 [即时演练3]——将下列句子改为被动语态 (1)She bought her mother a new coat. →　Her mother was bought a new coat by her. →　A new coat was bought for her mother by her. (2)We should make full use of our spare time to develop our interests. →　Our spare time should be made full use of to develop our interests. (3)I heard him sing in the classroom after school. →　He was heard to sing in the classroom after school by me.

(2)More than half of Australian homes are still choosing to stick with their home phone. (3)Now that you have made your promise，you are supposed to stick to it. [写美]——续写佳句 (4)我经过时，他伸出腿来想把我绊倒。 As I passed, he stuck out a leg and tried to trip me up. [重点句型] ●现在分词(短语)作结果状语 [经典例句] In China, a man from Jiangsu Province graduated from university at the age of 88, making him the oldest university graduate in the country. 在中国，江苏省一位88岁的老人从大学毕业，使他成为全国年龄最大的大学毕业生。 (1)现在分词(短语)作结果状语表示意料之中、自然而然的结果，分词前可加thus以示强调；常位于句末，用逗号与主句隔开； (2)不定式(短语)作结果状语常表示出乎意料或不好的结果，其前常加only表示强调。 [练通]——单句语法填空 (1)Millions of acres of wetlands were dried to feed and house the ever­increasing populations, greatly reducing　(reduce) waterfowl habitat. (2) Tom jumped into the house with joy，only to find　(find) the house empty. [写美]——句式升级 (3)Online learning itself has some imperfections, and makes it difficult for us not to be affected. →Online learning itself has some imperfections，　making it difficult for us not to be affected　.(现在分词作状语) Ⅰ.单句语法填空 1．The more regularly they can be inspected　(inspect), the more railway safety, reliability and on­time performance will be improved (improve). 2．Travelling to conferences, lectures, workshops, and the like — frequently by plane — is viewed/has been viewed (view) as important for scientists to get together and exchange information. 3．Currently, about 35，000 works are being displayed　(display) in over 300 rooms in the Louvre, and it would take a lifetime to see everything. 4．The parts of a museum open to the public are called　(call) galleries or rooms. 5．And, as more children were born, more food was needed　(need). 6．The woman was walking about outside the operation room, because her son was being operated　(operate) on. 7．They are trying to make sure that the project will be finished　(finish) by deadline. 8．A rescue worker risked his life saving two tourists who had been trapped　(trap) in the mountains for two days. 9．Children younger than 12 would be allowed　(allow) only to play the game for a maximum of one hour a day, and after 9 p．m., they would be banned from logging on (登录), said Tencent. 10．The opinion that learning is a lifelong process has been expressed　(express) by education experts throughout the years.
