wildlife”翻译成汉语，然后对照助读译文自主勘误助读译文：戴茜是如何学会保护野生动物的戴茜一直以来都渴望帮助那些濒临灭绝的野生动植物。一天她醒来，发现床边有一块飞毯。飞毯问：“你想去哪儿？”戴茜立刻回答道：“我想去看看濒临灭绝的野生动物。请带我到遥远的地方，在那里我可以发现为制作这件毛衣而提供毛绒的那种动物。”飞毯立刻开始起飞了，带她到了中国的西藏。在那里，戴茜看到一只藏羚羊面带忧郁的神色。它说：“为了取得我们肚皮底下的羊毛，我们正在被屠杀。我们的毛被用来为像你一样的人们制作毛衣。因此，我们现在濒临灭绝了。”听了这话，戴茜哭了：“我很抱歉，我过去不知道还有这回事儿。我不知道应该采取什么措施去帮助你们。飞毯啊，请把我带到一个有野生动植物保护的地方去，好吗？”飞毯飞行得如此之快，以至于一转眼他们就来到了津巴布韦。戴茜转过身去，看到一头大象正望着她。大象问道：“你是来给我拍照的吗？”戴茜如释重负，突然笑了起来。“不要笑了，”大象说道，“我们过去是濒危动物，农民们总是惨无人道地捕杀我们。他们说，我们破坏了他们的农田，而旅游者的钱过去都流进了大型旅游公司。于是政府决定出面提供帮助。如果游客付给农民钱的话，他们允许游客来猎取一定数量的动物。如今农民高兴了，我们的数量也在增加。因此，为了拯救当地的野生动植物，他们也在做一些好事。”戴茜笑道：“这可是个好消息。这体现了野生动植物保护的重要性，不过，我还是想按照世界野生生物基金会(wwf)的建议来帮助你们。”飞毯再次升起，几乎一转眼他们就到了茂密的热带雨林。一只猴子一边擦着身体，一边望着他们。戴茜问它：“你在干什么呢？”它回答说：“我这样做可以防止蚊虫叮咬。当我发现一种千足虫，便把它擦在身上。它含有一种强效的药物可以防止蚊虫叮咬。你们应该多加关注我生活的热带雨林，并且懂得热带雨林的动物是如何在一起生活的。没有雨林，就没有动物，也就没有药物了。”戴茜很惊讶。“飞毯，请带我回家去，我可以告诉世界自然基金会，我们可以开始生产这种新药。猴子，请跟我回去帮忙吧。”猴子同意了，毯子飞回了家。当他们着地时，一切就开始消失了。两分钟后，什么都没了猴子也没了。这样，戴茜就不能制造新药了。但是，这是一次多么奇妙的经历呀！她学了那么多东西！而且，还有世界野生生物基金会呢

wildlife.6the question is being discussed at the meeting.7she is being examined by the doctor.8a library is being built in our school.自我总结1例句1使用的是现在进行时，谓语动词的构成为bedoing。2例句28运用的是现在进行时的被动语态，谓语动词的构成为bebeingdone。3观察以上例句可知，当把现在进行时主动语态的句子变为被动语态时，在be动词后加上一个being来体现现在进行时，然后再把动词的现在分词形式变成过去分词来表示被动。一、现在进行时的被动语态的构成肯定结构be(am/is/are)being done否定结构be(am/is/are)notbeing done一般疑问结构be(am/is/are)主语being done特殊疑问结构特殊疑问词be(am/is/are)主语being donethe plan is being carried out this month.(肯定句)计划本月正在执行。your computer is not being repaired now.(否定句)现在没人修理你的电脑。are these fields being watered this week？(一般疑问句)这周有人在给这些地浇水吗？where are you being interviewed now？(特殊疑问句)现在你们在哪里接受面试？注意：现在进行时的被动语态表示主语是谓语动词动作的承受者，且强调此动作正在(被)进行。二、现在进行时的被动语态的用法1表示此时此刻正在进行的被动的动作。my sister is now being interviewed.我妹妹正在面试。2表示现阶段正在进行的被动的动作(该动作在说话的瞬间未必正在进行)。many interesting experiments are being carried out these days.如今许多有趣的实验正在被进行着。3表示一种经常性的被动行为，常和always，constantly 等表示频度的副词连用，这种用法常常带有赞扬或厌恶的感情色彩。he is always being praised by the leader.他总是受到领导的表扬。4表示按计划或安排主语将要承受谓语动词所表示的动作(仅限于少数及物动词)。a party is being held tonight.今晚将要举行一场晚会。三、使用现在进行时的被动语态要注意的问题1不可漏掉being，若漏掉，则成为一般现在时的被动语态或系表结构。2可与部分情态动词连用，表示对正在发生的事情的推测。she may be being punished by her mother.她也许正被母亲惩罚着。3有时可表示按计划或安排将要进行的一个被动动作。a celebration is being held this weekend for his success.这个周末将为他的成功举办庆祝会。4某些表示“状态、心理活动、存在”等的动词，如：have，want，need，love，一般不用现在进行时的被动语态，而常用一般现在时的被动语态。with the population increasing，more land is needed.随着人口的增长，需要更多的土地。5“beunder/inn.”可表示现在进行时的被动意义。my computer is under repair.my computer is being repaired.我的电脑正在维修中。一、用所给单词的正确时态和语态填空1can i use your telephone?sorry，the telephone is_being_used(use) now.2i dont suppose the teacher knows who broke the vase.well，surprisingly she does.tom has been called and is_being_questioned(question) now.3the young man is unhappy recently because he is always being_asked(ask) to give his wife money.4kevin is
