今年的寒假是个不平凡的寒假。由于新型冠状病毒，开学时间延迟。为了保证教学工作的正常进行，学校开展了网络课程。今天是网上教学的第四天，同学们都慢慢适应了这种新颖的教学方法，也没有因为老师的监督而松懈了自己的学习，在课上积极回答老师的问题，认真听讲，课后也按时完成自己的作业。而成为“主播”的老师们轮流完成各门学科的授课，上课很积极，课件准备的很用心，知识点也总结的很到位。我感觉这次网上教学的方法，即能保护同学和老师的安全，又能进一步激发同学们学习的兴趣，从而提高学习的效率。
This years winter vacation is an extraordinary one. Due to the novel coronavirus, the school hours are delayed. In order to ensure the normal progress of teaching, the school launched the network course. Today is the fourth day of online teaching. The students have gradually adapted to this new teaching method, and have not slackened their study due to the supervision of the teacher. They actively answer the teachers questions in class, listen carefully, and finish their homework on time after class. The teachers who become the \"anchor\" take turns to complete the teaching of various subjects. They are very active in class, attentive in courseware preparation and in place in knowledge summary. I feel that this online teaching method can not only protect the safety of students and teachers, but also further stimulate students interest in learning, so as to improve the efficiency of learning.
2020年春节，一场新型冠状病毒引发的肺炎疫情笼罩了中华大地。人们开始足不出户，生活变得压抑起来。在这样的背景下，教育部发布通知“停课不停学”，正式开辟了一种崭新的学习方式，网上授课。
A novel coronavirus epidemic caused by pneumonia in 2020 was enveloped in China. People began to stay indoors and life became oppressive. In this context, the Ministry of Education issued a notice of \"no suspension of classes\", officially opening up a new way of learning, online teaching.
每天在钉钉直播群里上课，我认为这种教学方式变得生动活泼，我的学习兴趣也提升了许多。老师们每节课在直播间里以课件的形式向我们授课，整节课的.知识框架变得清晰明朗了起来，这是十分有利于我们接受并消化东西的。
Every day in nail live group classes, I think this teaching method has become lively, my interest in learning has also increased a lot. Teachers teach each lesson to us in the form of courseware in the live room. The knowledge framework of the whole lesson becomes clear and clear, which is very conducive to our acceptance and digestion.
其次，就是这种方式突破了原有的教学模式。在学校是每一个学科只有一个老师授课，但在网上授课则是许多不同的老师担任我们的任课老师，使我们能充分了解到不同老师的教学风格和特点，进而可以得知自己感兴趣的教学方式。
Secondly, this way has broken through the original teaching mode. In school, there is only one teacher for each subject, but in online teaching, many different teachers are our teachers, so that we can fully understand the teaching styles and characteristics of different teachers, and then we can know the teaching methods we are interested in.
再者，在网上授课时，每个老师一天只需上一节课或两节课，这就为老师们挤出了充足的时间为同学们批改作业及写评语，可以使同学们了解到自己作业的不足和突出的地方，之后就知道我们可以向哪一个方向努力。
Moreover, in online teaching, each teacher only needs to have one or two classes a day, which makes the teachers have enough time to grade and write comments for the students, so that the students can understand the shortcomings and highlights of their own work, and then know which direction we can work in.
总而言之，我们在这足不出户的冬日勃发着学习的兴趣。“冬天来了，春天还会远吗?”我相信，只要我们认真进行网上学习，永远保持着学习的自信，总有一缕阳光，会突破疫情的阴霾，带来温暖的春天。待到春暖花开时，我们再聚校园。
All in all, we are interested in learning in this winter. \"If winter comes, will spring be far behind?\" I believe that as long as we carefully carry out online learning and always maintain our confidence in learning, there will always be a ray of sunshine, which will break through the haze of the epidemic and bring warm spring. When spring comes, we will get together on campus.

现在疫情当前，为了学生安全，不集聚在一起，我们不能到学校上课，历史上放得最长的一次寒假。为了我们学习，老师在网上直播辅导我们学习。
At present, for the sake of the safety of students, we cant go to school without gathering together. Its the longest winter vacation in history. For our study, the teacher tutored us live online.
为了这次疫情，全国各省各地展开“停课不停学”老师直播上课行动，许多教育机构推出各种学习软件。名师在线免费教学，帮助学生学习，在线辅导。
In order to deal with the epidemic, all provinces and regions across the country launched a live action of \"no suspension of classes\" for teachers, and many educational institutions launched various learning software. Famous teachers online free teaching, help students learn, online tutoring.
因为上网课直播，各省老师出现了不同的争论。湖南哪吒“对多数学生说，网课的授课效果根本得不到保证，这种形式主义何必存在？”我觉得湖南老师说得不错，上网课，有一部分爱学习的学生能坚持上网课，但是有一部分不自律的同学开着直播就该干嘛干嘛去。所以说上网课不一定得到学习效果。
Because of the live broadcast of online classes, teachers in various provinces have different arguments. Hunan Nezha said to most students that the teaching effect of online courses is not guaranteed at all. Why does this formalism exist I think Hunan teachers are right. In the online class, some students who love learning can insist on the online class, but some students who are not self disciplined can do what they should do when they open the live broadcast. So online classes dont necessarily get learning results.
我个人是觉得上网课没什么学习效果，上网课，老师在线直播辅导各同学，但是人数多，老师又不能每一个人都顾及得到，每个人的问题不一样，只能挑重点讲。一个人在房间里学习，没有在学校教室里学习氛围好。作息时间混乱，晚上熬夜，晚睡觉，预定多个闹钟。早上起来打完卡接着睡。上网课老师不能面对面教导，许多同学都是敷衍了事。老师与同学之间缺乏互动，对于学习好求者可能受益匪浅，但是对于厌倦学习者，学习上没有一点效果，需要老师面对面教导，当面监督学习情况。
Personally, I dont think the online class has any learning effect. The online class and the teachers live online tutoring for each student have a large number of students, but the teacher cant take everyone into consideration. Everyones problems are different, so we can only focus on them. A person in the room to study, not in the school classroom learning atmosphere. The schedule is chaotic. Stay up late, go to bed late, and reserve multiple alarm clocks. Get up in the morning, punch in and go to sleep. Teachers cant teach online lessons face to face, many students are perfunctory. The lack of interaction between teachers and students may benefit those who are good at learning, but for those who are tired of learning, there is no effect in learning. Teachers need to teach face-to-face and supervise learning face to face.
上网课对贫困家庭来说，不方便，有可能老是断网，要是家庭人口多的家庭，孩子都在上网课有可能网络卡。住在农村里的有一些没有信号不好的同学来说也麻烦，不能好好上网课。对上小学的同学们都是没有手机的，父母要出去工作，根本起不到学习作用。
Internet class is inconvenient for poor families. It is possible to always disconnect from the Internet. If there is a family with a large population, it is possible for children to use Internet cards in Internet class. Living in the countryside, some students who dont have a good signal are also in trouble. They cant have a good online class. There is no cell phone for the students in primary school. If parents want to go out to work, they cant learn at all.
学生的专注不在直播上，面对着QQ、微信、游戏、电视的诱惑，有很多学生难以拒绝诱惑，没有吧精力放在上网课上。老师也不知道学生在干什么，人数过多，有的学生一边手机上网课，一边睡觉。或者手机上网课，而学生却在看电视。手机电脑电视对眼睛视力有一定影响，对眼睛不好。
Students focus is not on live broadcast. Facing the temptation of QQ, wechat, games and TV, many students are hard to resist the temptation and have no energy to focus on online classes. Teachers also dont know what students are doing. There are too many students, some of whom are sleeping while taking lessons on the Internet. Or mobile Internet class, while students are watching TV. The mobile phone computer TV has certain influence on the eyesight, but it is not good for the eyes.
所以我觉得，上网课不一定取得到老师授课学习效果，有一些学生未能适应网上学习。学习情况未能得到提升。但是在这个特殊时期，我们现在只能在网上学习了，无论如何，还是希望各位同学们认真上网课，能学一点是一点了。希望学校开学通知早一点来，开始怀念在教室里面学习的日子了。
So I dont think that online classes can achieve the effect of teaching and learning by teachers, and some students cant adapt to online learning. Learning has not been improved. But in this special period, we can only learn online now. In any case, I hope that all the students will take online classes seriously and learn a little bit. I hope that the school notice will come earlier and start to miss the days of studying in the classroom.

按要求改写句子知识点梳理
一、概述
按要求改写句子主要考查学生对句子结构的掌握以及用不同句型表达同一意思的能力。考查所涉及到的句子类型有一般疑问句、否定句、反意疑问句、选择疑问句、对划线部分提问、感叹句、保持原句意思、合并成一句、简单句和复合句之间的互换以及改为被动语态等。
二、解题时需注意的几个要点
1、时态：不同的时态相对应的助动词
一般现在时：谓语动词用原形（主语为第三人称单数时，动词加s或es，变否定句、疑问句时助动词为do或does）
一般过去时：谓语动词用过去式，变否定句、疑问句时助动词为did.
现在完成时：助动词have/has+动词的过去分词
过去完成时：助动词had+动词的过去分词
一般将来时：will/be going to +动词原形
过去将来时：would/was or were going to +动词原形
现在进行时：am/is/are＋动词的现在分词
过去进行时：was/were＋动词的现在分词
2、语态：主动语态变为被动语态的谓语结构
一般现在时：am/is/are＋动词的过去分词
一般过去时：was/were+动词的过去分词
一般将来时：will be+动词的过去分词
情态动词：can/may/must/need等情态动词＋be++动词的过去分词
3、改反意疑问句时注意hardly, never, seldom, few, little, no等词表达的是否定意义，变反意疑问句时用肯定形式。
4、在合并句子时，有些连词如not only…but also…, neither…nor…, either…or…是就近原则，连接两个主语时动词形式取决于与动词邻近的主语。而both…and…连接两个主语时,主语是复数。
5、简单句和复合句之间的互换常见的有：带有疑问词的宾语从句改为特殊疑问词＋to＋动词原形的不定式；结果状语从句so…that…改为enough to或too…to…的简单句。
6、保持原句意思改写句子时注意时态不变。
