    【语法解析】

    ②Much is being done to protect wildlife, but if we really want to save the planet, we must change our way of life.
    ③These large animals are being killed illegally for their body parts that are considered valuable.
    [我的发现]
    句①②③中均使用了现在进行时的被动语态,其结构为:am/is/are+being done。
    一、基本结构:  
    1.现在进行时态的被动语态的肯定式为:
    am/is/are + being + done。
    如:The question is being discussed at the meeting now.       
    这个问题现在正在会上被讨论。  
        Another bridge is being built over the Changjiang River at present.       
    目前长江上正在建造另一座大桥。  
    2.现在进行时态的被动语态的否定式为:am/is/are + not + being + done。
    如:The baby isn’t being taken good care of.   这婴儿没在得到很好的照顾。  
     The animals are not being set free at present.   目前这些动物还不能被放出。  
    3.现在进行时态的被动语态的一般疑问句需将am/is/are 提到主语的前面。    
    ---Is a new library being put up in their school now?
    ---Yes, it is.    
    甲:他们学校现在正在建一座新图书馆吗。
    乙:是,正在建一座新图书馆    
    ---Are a number of Dongfeng trucks being shipped abroad?  
    ---No, they aren’t.     
    甲:一批东风卡车正被运往国外吗?
    乙:不,没有。  
    4.现在进行时态的被动语态的特殊疑问句为:疑问词 + am/is/are + (主语) + being + done。  
    如:What is being done to the machine?   
    现在对这台机器要采取什么措施?  
     How many houses are being built in the village?   
    村里正在建造多少房屋?  
     When is the sports meeting being held in our school?    
    我校将在什么时候举行运动会?

    二、用法:   
    1.现在进行时态的被动语态的同它的主动语态一样,表示现在正在进行的被动动作。  
       He is being interviewed by our headmaster now.   
    他正在接受我们校长的采访。     
    This film is being shown now.   
    这部电影正在被放映。  
    2.现在进行时态的被动语态的同它的主动语态一样,表示现阶段正在进行的被动动作。  
       The disease is being studied by scientists.   
    科学家们正在研究这种疾病。  
       These animals are being hunted at such a speed that they will disappear soon.    
    以如此速度捕杀动物,他们很快就会消失。

    三. 现在进行时被动语态五个提醒  
    1不可遗漏being 
    现在进行时的被动语态表示说话时主语正在承受谓语动词的动作,谓语动词的形式为“is/are/am+being+过去分词”。如果把being漏掉,就成为一般现在时被动语态或系表结构。试比较下列句子:
    Look! The children are being taken care of by their aunt.  
    瞧!孩子们现在正由姑母照看着。
    Children are taken good care of at school.  
    孩子们在校被照看得很好。(指通常情况)  
    The report is being written by one of the best students.  
    报告正在由一个最好的学生写着呢。  
    The report is well written.  
    报告写得很好。(系表结构)
    2表示现阶段  
    现在进行时被动语态也可以表示目前这一阶段主语正在承受谓语动词的动作。
    Many interesting experiments are being carried out these days.  
    最近正在进行许多有趣的实验。(说话时,并不一定在进行)      
    3表示计划或安排  
    现在进行时被动语态还可表示按计划、安排主语将要承受谓语动词的动作(仅限于bring,take,send,hold,sing,show,play等表示移动的或能用来表示某项活动的少数及物动词)。 A folk song is being sung next.  
    下面将演唱一首民间歌曲。
    A party is being held tonight.   
    今晚将要举行一场晚会。
    4没有进行时被动语态  
    contain,include,impress,feel,want,like,love,satisfy,surprise,own等一些表示状态、心理活动、拥有等意义的动词(和主动语态一样)一般不用进行时被动语态,常用一般现在时被动语态表示此时此刻或目前主语承受谓语动词的动作。  
    Xiao Wang, come here. You are wanted on the phone. ?  
    小王,过来,有人打电话找你呢。  
    Football is becoming more and more popular. In other words, it is loved by more and more people.   
    足球现在越来越流行了,换句话说,它被越来越多的人喜爱。
    5其它形式表示被动结构  
    “be+under/in等介词+名词”结构可代替进行时被动语态。
    The city is under attack(=is being attacked)at the moment.   
    目前这个城市正受到进攻。  
    The telephone is in use(=is being used)now.  电话正在使用中。

    Ⅰ.阅读理解
    A
    International Tiger Day is an annual celebration to raise the awareness of tiger conservation.It's held on 29 July.Governments and citizens across the world organize awareness programs on that day to spread the importance of protecting tigers.
    From ancient times, tigers were the subject of constant attraction for their beauty, size and sometimes mythical (神话的) stories related to them.People's fascination (迷恋) for tigers is obvious from the fact that tigers are still a part of many national symbols and flags.Tigers are the largest cat species.Unfortunately, the population of tigers is fast decreasing.Every part of tigers from tail to skin to nail is traded in the illegal market for very high values.Many tigers are hunted, which is one of the key threats to their existence.They are also caught and raised as pets.97 percent of the world tiger populations decreased in the last 100 years and only 3,890 tigers are left.If tigers get extinct, we will lose a species.And it also means that enough forests have been destroyed, which may endanger many other species.
    For us, tigers are symbols of wildlife's fighting for survival.It reminds us of the dangers we face because of people's over­exploitation (过度开发) of the nature.It's an opportunity as well.Many efforts are on the way to double the tiger population by 2022.Strict national and international laws are against hunting and trading tigers.As a result, the number of tigers in the wild has risen for the first time in more than 100 years.Even though this is just a small increase, it's a huge symbolic victory in our efforts against the destruction of forests and wildlife.It's very important that we all join together in this effort, not only to save tigers, but also to save our forests.
    语篇解读:本文是一篇说明文。文章主要讲述了由于种种原因,老虎一直成为人类猎杀的动物并濒临灭绝,现在人类正为保护老虎做出种种努力。
    1.What can we learn about International Tiger Day?
    A.It's celebrated on 29 June.
    B.It's held once every four years.
    C.Lots of money is collected on that day.
    D.Some activities are held worldwide for it.
    解析:选D 细节理解题。根据第一段中的Governments and citizens across the world organize awareness programs on that day to spread the importance of protecting tigers.可知,在国际老虎日那一天,人们会组织很多活动,让人们意识到保护老虎的重要性。
    2.According to Paragraph 2, how do people feel about tigers?
    A.Tigers are uncommon.
    B.Tigers might destroy their homes.
    C.Tigers are very dangerous animals.
    D.Tigers can be used to show a nation's spirit.
    解析:选D 推理判断题。根据第二段中的People's fascination (迷恋) for tigers is obvious from the fact that tigers are still a part of many national symbols and flags.可推断,人们认为老虎是他们国家精神的象征,因此其图案常出现在国旗上。
    3.The population of tigers is fast decreasing mainly because .
    A.they are hunted for trade in illegal markets
    B.they are not as healthy as before
    C.many people keep them as pets
    D.some of them are kept in zoos
    解析:选A 细节理解题。根据第二段中的Every part of tigers from tail to skin to nail is traded in the illegal market for very high values.Many tigers are hunted, which is one of the key threats to their existence.可知,老虎在市场上被非法买卖是造成其数量快速减少的主要原因。
    4.Which of the following may the author agree with?
    A.The lack of food is the key threat to tigers' existence.
    B.We should put more effort into protecting tigers.
    C.We've got great success in protecting tigers.

    解析:选B 推理判断题。根据最后一段的内容可知,作者认为我们必须采取更多措施保护老虎。
    B
    One night, I was happily making my tea when all of a sudden the room was in complete darkness.The lights had gone out, the oven (烤箱) stopped working and my phone was no longer charging (充电).I tried to fix the electricity but I soon realized that I couldn't.I had to wait for an electrician to come in the morning.
    After messaging my friends to say that I wouldn't message that night because I couldn't charge my phone, I sat down to eat my half­cooked dinner.And then I wasn't sure what to do.I usually spend my evenings watching TV and going on the Internet.I couldn't even read a book because I wasn't prepared with candles.So for me, it was an early night.
    Losing our electricity felt like losing a basic necessity.In fact, electricity is a luxury (奢侈品).But we think it will always be there when we need it.I use electricity all the time, even when it's not really necessary.I use it to put the TV on even when I'm not really watching it.I use it to check my phone when I wait for a friend.
    Our overuse of electricity is a big problem.It is one of the causes of global (全球的) warming, which is harming our environment and we need to do what we can to stop it.Not only that, but if we continue to overuse it we will soon run out.
    We wouldn't want to live in a world without electricity, but we will run out one day.So, shouldn't we start preparing for it now? Cutting back on our use of electricity saves energy resources (资源) so that they can last longer.I know for sure that I could cut down on my use of electricity.If everyone does the same, we can make a difference.
    语篇解读:本文是一篇记叙文。经过一次停电事件,作者开始反思自己过度依赖和浪费电资源的情况,呼吁大家节约能源。
    5.What did the author do when the electricity went out suddenly?
    A.He tried to fix it and succeeded.
    B.He messaged his friends for help.
    C.He called an electrician immediately.
    D.He stayed in darkness the whole night.
    解析:选D 推理判断题。由第一段中的I had to wait for an electrician to come in the morning.和第二段中的I wasn't prepared with candles可知,突然停电之后,作者只能等待电工第二天早晨来修,而且作者没有准备蜡烛,因此可推断,作者不得不整夜处在黑暗之中。
    6.What does the underlined sentence in Paragraph 2 show?
    A.The author was unsure what to do.
    B.The author had nothing to do but sleep.
    C.The author was tired after the accident.
    D.The author didn't want to do any reading.
    解析:选B 句意理解题。由第二段内容可知,由于停电,作者无法做自己平时所做的事情,作者也没有准备蜡烛,无法读书,因此只能早睡。
    7.What is Paragraph 4 mainly about?
    A.The results of overusing electricity.
    B.The examples of overusing electricity.
    C.The ways of using electricity properly.
    D.The suggestions on producing electricity.
    解析:选A 段落大意题。第四段主要介绍了过度使用电资源的后果:导致全球变暖,进而危害环境,而且过量使用电资源会使其很快耗尽。
