①苏东坡刚入官场时,还不叫苏东坡。他本名苏轼,字子瞻,另外他还有一个雅号,叫作苏贤良。②那年他金榜高中,名动京师,正在自我陶醉,却不料被派到既偏又穷的陕西凤翔府,当了个小小的签判(秘书),自不免有大材小用之感。说实话,他全靠“苏贤良”这个尊称活着呢!
电视剧《火红年华》两度在央视播出,让全国观众领略了“三线精神”诞生地——四川攀枝花的“根”与“魂”。这部剧的拍摄地大多选址于攀枝花市西区,剧中充满年代感的红砖房、蜿蜒曲折的背水小道,给人们留下了深刻印象。
Bike-to-Work Day is held every year across North America on thethird Friday of May. It was started by the League of American Bicyclistsin 1956. Its aim is to promote (促进) the bicycle as a serious choice of getting toand from work. In today’s world where global warming is a serious issue, thebicycle is a perfect way of reducing our carbon (碳) footprint.

其次,这次学习让我认识到自我的不足。第一,知识要更新,做到边干边学,“不能一本通书读到老”。应该多学习教育学理论和教育教学方法,教育教学技能要进一步提高和增强,否则就跟不上教育的节拍。第二,敬业精神有待提高,一直以来,本人对教材的研究不够深刻,大多数时候都是上课前看一下课文就去上课了,缺少刻苦钻研教材的精神。另外,在对待学生的耐心方面做得也不够,对于差生和后进生没有耐心去辅导他们,对他们的思想动态了解不够,因此解决时常常不能得心应手。
1、以身示范——以情感染每一个学生在课堂上,要对学生进行孜孜不倦的教导,一丝不苟地传授书本的知识。在日常生活中,从道德、行为、言谈、学风等方面对学生进行严格的要求,制定出行之有效的措施。对于教育工作,老师应做到不计较报酬,不讲条件无私奉献,教师既要向学生传授课本的知识,也要传授有关社会生活中的知识。在午间休息中,老师要率先示范,言传身外。老师是学生的朋友,要让学生愉快而又很好地接受老师灌输的知识并与老师做"知心朋友":首先要做的就是要消除师生之间的"代沟".只要能掌握学生的心理,老师就可以抓住其中的某些因素因人施教,要做好这些工作,老师要深入到学生群体中,跟每个学生一一谈心,与他们做知心朋友,从中了解他们的优点、缺点、爱好和困难等,在课堂上和平时的生活中对他们的点滴进步进行表扬和鼓励,使他们树立自信心,因为教师事业是一首爱心赞歌,是需要付出心血的,要我们的教师有耐心、有恒心、有爱心才能散发出的高尚的师风师德。

过渡:在实际生活中,城市内部空间结构并非完全按照这一经济规律呈现,而是更具复杂性。这说明除了经济因素外,还有很多其他因素在起作用,请大家结合你的认识、图2.9和案例1:纽约市的少数民族区谈谈你的看法。(2)其他因素I.收入 —— 形成不同级别住宅区的常见原因。有能力支付昂贵租金和选择最佳居住环境的人,其居住地往往形成高级住宅区。II.知名度 ——城市内某些地区在历史、文化或经济方面具有很高的声誉,这往往会吸引更多新的住宅或商场建在该处,以提高其知名度。III.种族聚居区的形成 ——在有些城市的某一区域内,如果某个种族或宗教团体占优势,就可能形成种族聚居区。如纽约市的唐人街、哈林区、小意大利区等。IV历史因素——城市的建筑物和街道设计可以维持久远,早期的土地利用方式对日后的功能分区有着深远的影响。3、城市内部空间结构的形成和变化

1、第一,材料一和材料二的选举方式有什么异同?(1)相同点:①都采用了演讲和答辩等形式,都带有竞选的性质;②都采用无记名、直接选举的方式进行投票选举;③都属于差额选举。(2)不同点:①材料一是对村主任进行的正式选举,结果是直接产生村主任,材料二是对镇长候选人进行的选举,结果只是确定镇长候选人,镇长人选还有待进行正式选举;②材料一是全体村民都参加选举,材料二是各户派代表参加选举;③材料二比材料一更强调竞选的方式。第二,你还知道哪些选举方式?除了直接选举外,还有间接选举、等额选举、差额选举等。第三,你能对这几种选举方式的意义和效果,作出自己的评估吗?这是学习中要探究的问题,这里不一定能回答出来,等到学完本框内容后,可以得出比较明确的答案。第四,材料三给了你什么启示?这个问题不要求统一的答案,能讲出一两点即可。提示如下:(1)新中国成立后,选举制度经历半个多世纪的发展,正在逐步走向完善;
The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.
Listening and Speaking introduces the topic of “talking about how to become an astronaut”. This period is aimed to inform students some details about the requirements of being an astronaut. Students can be motivated and inspired by the astronauts. Teachers ought to encourage students to learn from them and let them aim high and dream big.Listening and Talking introduces the theme of "talk about life in space". This part also informs students more details about life in space and can inspire students to be curious about this job. 1. Guide students to listen for numbers concerning dates, years and ages etc2. Cultivate students' ability to talk about how to become an astronaut and life in space ; 3. Instruct students to use functional sentences of the dialogue such as “ first of all, I am not sure, so what might be .. I guess.. I wonder…I am curious…)appropriately.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to become a qualified astronaut and describe the life in space.Part 1: Listening and SpeakingStep 1: Lead inPredictionThe teacher can ask students to predict what the listening text is about by looking at the pictures.About how to become an astronaut./the requirements of an astronautStep 2: Then, play the radio which is about an interview a. And after finishing listening for the first time, the students need to solve the following tasks.

另一方面,其余的人反对这个计划,因为它可能会导致一些不好的影响。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我坚信探索太空不仅能够使我们了解宇宙的起源而且能够帮助我们更好地走进未来。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.为了给人类的短期和长期问题提供更新和更好的解决方法,我认为我们应该花更多的时间和金钱来探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看来,年轻人过度依赖手机是不对的,因为它们可能会对他们的身心健康都有害。最近你班同学就“人类是否应该进行宇宙探索”这个问题进行了激烈的讨论。有人认为,探索宇宙不仅让人类更好地了解宇宙的发展,还可以用来指导农业生产,以及把一些探索太空的高新技术用于现实生活;也有一些人认为探索太空花掉了大量的人力物力;影响了人们的生活水平。请你根据以下情况写一篇报告并发表自己的观点。注意:1.写作内容应包括以上全部要点,可适当发挥,使上下文连贯;
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
