?瞧!孩子们现在正由姑母照看着。(指现在的情况)
Children?are?taken?good?care?of?at?school.?

一批东风卡车正被运往国外。
Many?interesting?experiments?are?being?carried?out?these?days.
最近正在进行许多有趣的实验。 现在进行时被动语态的用法
1、表示现阶段正在进行的动作 ?现在进行时的被动语态表示此时此刻某事正在被做。2、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(仅限于少数及物动词)。
A?folk?song?is?being?sung?next.?
下面将唱一首民歌
A?party?is?being?held?tonight.?
今晚将要举行一场晚会。(1) 肯定形式：be (am, is, are) + being + 过去分词
?????Money is being collected for the Hope Project.
(2)否定形式：把 not 放在第一个助动词 am / is / are 之后，即：“be (am, is, are) + not + being + 过去分词”。
?????New nature parks are not being started in China. 现在进行时被动语态的形式(3) 疑问形式：把第一个助动词 am / is / are 移到句首并大写，句末加问号，即：“Be (Am, Is, Are) + 主语 + being + 过去分词?”
????Are elks being sent to China from Britain?
(4) 特殊疑问句形式：其构成在多数情况下是把特殊疑问词直接加在一般疑问句之前，具体可分为以下三种情况：
????1) 疑问句(作主语)+ is being + 过去分词 + 其它?
What is being done on the life of pandas? 2) 疑句词 (作定语) +主语+ is / are being + 过去分词 + 其它?
?????How many buildings are being built in the town?
3) 疑问词 + is / are + 主语 + being + 过去分词?
?????Where is the elk being studied by scientists? 1）“be being done” 中的be应随被动句中的主语作相应的变化。
2）将现在进行时的主动语态变为现在进行时的被动语态的关键是：把be doing变为be being done.

如何写建议信类书面表达?Writing 建议信是书信的一种形式，属于应用文文体。建议信是写信人向收信人就某事提出自己的建议或忠告。有可能是写给个人，就其遇到的某个问题提出自己的看法和忠告；也可能是写给某个组织或机构，就改进其服务等提出建议。
建议信要写出写a信的目的、建议的内容、提出建议的理由和根据。理由要合情合理，语气一定要礼貌。
建议信的正文通常采取“三段式”结构。
首段：一般说明建议的前提和事情的原委，对自己的立场作一些解释。
中段：围绕问题，思路清晰并且委婉地提出有针对性的建议。注意考虑对方的实际情况，切忌用语生硬、泛泛而谈。
尾段：简单予以希望。希望自己的建议能对对方有所帮助，同时阐明所提供的建议仅供对方参考。写作指导【注意事项】
1)语气和用词要得体。在劝说对方接受你的建议时，应该注意措辞，慎用must等命令性词汇。要用协商性、试探性的语气提出建议，避免用生硬说教的口吻。
2)要传达特定的信息。首先要点明写信的目的是提建议；然后简要描述问题，提出建议并具体分析所提出的建议；最后真诚地希望对方能接受自己的建议，并礼貌地结束全文。
3)结构要合理。要合理安排所有内容，使文章有条理，符合逻辑。I)建议信开头常用句式：
You have asked me for my advice on… and I will try to make some suggestions．
I’m writing to give some suggestions to…
I’m writing to share with you my opinions.

上海博物馆拟举办一次名画展，现就展出场所（博物馆还是社区图书馆）征集公众意见，假设你是王敏，给上海博物馆写一封信表达你的想法。你的信必须满足以下要求：
1. 简述你写信的目的及你对场所的选择；
2. 说明你的理由（从便利性，专业性等方面对这两个场所进行对比）
实战演练参考范文：
I’ve learned that you’re collecting suggestions on the location of the coming art exhibition. I know it will make our city more beautiful. I’m writing to share with you my opinions.
In my view, it is much better to hold the art exhibition in Shanghai Museum than in community libraries. My reasons are as follows:
Firstly, it is easy for the citizens to go to Shanghai Museum because it lies in the center of the city. Besides, it gives people a more comfortable environment for appreciating art.
Secondly, Shanghai Museum is famous for being professional and experienced in holding art exhibitions, so it is certain to meet people’s demands. The museum can better protect those famous paintings from being damaged or stolen.
I hope you can give a thought to my advice which I believe will help.
Wang Min 【点评】
本题写作要求就一次名画展的展出场所（博物馆还是社区图书馆）从便利性，专业性等方面提出合理化的建议。文章结构合理，条理清楚，符合逻辑，语气和用词得体，，理由和根据充分。正文采用了建议信“三段式结构”：信的第一段交待了自己的身份，并且表明了些这封信的目的。第二段明确提出了自己的观点，用了it is much better to do...句型，表明“……是更合理的”。段落最后用My reasons are as follows.“我的理由如下”作为一个过渡句引出下面的理由论述。第三、四段用firstly, besides, secondly “首先……；此外……，其次……”进行连接，层次清楚。在论述观点时连词的使用可以使逻辑显得更清晰。第三段从便利性角度进行分析，博物馆交通更便利而且环境更舒适。第四段从专业性角度说明博物馆的优势。最后一段总结并重申自己的观点。
文中用了许多地道的短语，如make our city more beautiful，in my view，be famous for，protect …from…, give a thought to等，为文章增色不少。

如何写建议信类书面表达?Writing 建议信是书信的一种形式，属于应用文文体。建议信是写信人向收信人就某事提出自己的建议或忠告。有可能是写给个人，就其遇到的某个问题提出自己的看法和忠告；也可能是写给某个组织或机构，就改进其服务等提出建议。
建议信要写出写a信的目的、建议的内容、提出建议的理由和根据。理由要合情合理，语气一定要礼貌。
建议信的正文通常采取“三段式”结构。
首段：一般说明建议的前提和事情的原委，对自己的立场作一些解释。
中段：围绕问题，思路清晰并且委婉地提出有针对性的建议。注意考虑对方的实际情况，切忌用语生硬、泛泛而谈。
尾段：简单予以希望。希望自己的建议能对对方有所帮助，同时阐明所提供的建议仅供对方参考。写作指导【注意事项】
1)语气和用词要得体。在劝说对方接受你的建议时，应该注意措辞，慎用must等命令性词汇。要用协商性、试探性的语气提出建议，避免用生硬说教的口吻。
2)要传达特定的信息。首先要点明写信的目的是提建议；然后简要描述问题，提出建议并具体分析所提出的建议；最后真诚地希望对方能接受自己的建议，并礼貌地结束全文。
3)结构要合理。要合理安排所有内容，使文章有条理，符合逻辑。I)建议信开头常用句式：
You have asked me for my advice on… and I will try to make some suggestions．

上海博物馆拟举办一次名画展，现就展出场所（博物馆还是社区图书馆）征集公众意见，假设你是王敏，给上海博物馆写一封信表达你的想法。你的信必须满足以下要求：
1. 简述你写信的目的及你对场所的选择；
2. 说明你的理由（从便利性，专业性等方面对这两个场所进行对比）
实战演练参考范文：
I’ve learned that you’re collecting suggestions on the location of the coming art exhibition. I know it will make our city more beautiful. I’m writing to share with you my opinions.
In my view, it is much better to hold the art exhibition in Shanghai Museum than in community libraries. My reasons are as follows:
Firstly, it is easy for the citizens to go to Shanghai Museum because it lies in the center of the city. Besides, it gives people a more comfortable environment for appreciating art.
Secondly, Shanghai Museum is famous for being professional and experienced in holding art exhibitions, so it is certain to meet people’s demands. The museum can better protect those famous paintings from being damaged or stolen.
I hope you can give a thought to my advice which I believe will help.
Wang Min 【点评】
本题写作要求就一次名画展的展出场所（博物馆还是社区图书馆）从便利性，专业性等方面提出合理化的建议。文章结构合理，条理清楚，符合逻辑，语气和用词得体，，理由和根据充分。正文采用了建议信“三段式结构”：信的第一段交待了自己的身份，并且表明了些这封信的目的。第二段明确提出了自己的观点，用了it is much better to do...句型，表明“……是更合理的”。段落最后用My reasons are as follows.“我的理由如下”作为一个过渡句引出下面的理由论述。第三、四段用firstly, besides, secondly “首先……；此外……，其次……”进行连接，层次清楚。在论述观点时连词的使用可以使逻辑显得更清晰。第三段从便利性角度进行分析，博物馆交通更便利而且环境更舒适。第四段从专业性角度说明博物馆的优势。最后一段总结并重申自己的观点。
文中用了许多地道的短语，如make our city more beautiful，in my view，be famous for，protect …from…, give a thought to等，为文章增色不少。
