高效的课堂是时下课堂教学的主流，也是我们一线教师的追求，在听完仇海云老师的讲座后，感想很多如何让孩子们喜欢上这个第二语言，学在其中乐在其中，如何才能提高教学效率，打造高效课堂，我有以下几点浅显的认识：

一、激发学生学习英语的兴趣

新课标指出：激发和培养学生学习英语的兴趣，是学生建立自信心。养成良好的学习习惯和形成有效的学习策略，发展学生自主学习的能力和合作精神：是学生掌握一定的英语基础知识和听、说、读、写技能，形成一定的综合运用语言的能力，培养学生的观察、记忆、思维、想象力和创新能力，帮助学生了解世界和中西方文化的差异、拓展视野，培养爱国主义精神，形成健康的人生观，为他们的终身学习和发展打下良好的基础。

“兴趣是最好的老师”。这毋容置疑。作为小学生的启蒙英语老师，我们有责任有义务培养学生的兴趣，这个兴趣应该是具有持久性的、积极向上的特点的。而物质刺激的方法对任何人都适用，甚至是宠物，其所产生的兴趣只是短暂的，比较低级的。因此，老师应该从小学生的生理和心理特点出发，精心设计教法，把英语课与活动课相融合，让学生在活动中快快乐乐学英语。同时，教师可根据小学生好胜心强的特点，开展适当的竞争性游戏，通过小组竞赛的形式，采取加减分数、抢得红五星等多种方法，使学生在竞争活动中获得成功所带来的满足感、成就感。而且，这类活动还能增强学生的团结协作意识，培养学生的合作精神。

二、有效提问是提高课堂教学效率的关键

提问是触发学生思维的引言，是激发学生觉悟的契机，是教学检测的手段。提问的质量制约着教学进程能否推进，决定着教学效果的好坏。要运用好提问，应当注意这样几点：

1、提问要有计划性。一堂课要提问几个问题，对于所提问题的切入角度都要进行精心的构思。先问什么，后问什么，教师要胸有成竹，精心策划。提问要由表及里，由浅入深，步步深入。教师思路明晰，也对学生思维起着潜在的导向作用。

2、提问要有启发性。提问要促进学生思考，要减少或避免走过场的应答式提问——简单地问“对不对”、 “好不表面热闹，价值不大，好”这种应答式的提问，思维的含量很少，而这样的提问在教师实际课堂教学中大有存在。

3、提问要难易适度。有效备课中有个环节就是“备学生”， 学生接受能力有差异，所以我们说要因材施教。提问要根据学生的实际水平，不可过浅，以免走过场;又不可过难，以防学生茫然失措，产生畏难情绪。

三、采用丰富多彩的课堂活动

小学英语教学内容更多的是以日常交流语言为主，带有很强的情境性。而由于孩子随意注意稳定性较差。这就要求我们将枯燥的教学内容还原为实际生活，将课堂教学活化为交流情境。而丰富多彩的活动正是英语教学的情境化中介，是优化英语课堂的关键，是教师了解实际的策略，更是教与学的中介。英语教学活动化，教师应真正树立为学生服务的观念，遵循学生的心理发展和认识发展规律，精心设计课堂的每一个环节，采取种种方法，充分调动学生主体参与的积极性，做学生学习与活动的参谋者，引导者和组织者。从实际出发，精心设计各种新鲜的活动，全身心地投入课堂，对学生的差异要心中有数，对出现的问题及时发现，及时解决，要使学生乐于参与，使他们能够在学习中尽情地发挥自己的才能，充分地表达自己的思想，勇敢地阐述自己的观点，真诚地表露自己的感情。这样，才会有利于全面发展，使他们喜欢英语，喜欢上英语课。

四、及时的给与多种形式的积极评价

教育是一个从量变到质变的不断发展的活动过程，需要根据情况变化及时做出判断和决定，由此产生相应的教育评价。评价是英语课程的重要的有机组成部分，是实现课程目标的重要保障。传统的评价重结果，轻过程，忽视人文性，往往使很多学生一旦失败几次，从此就失去了学习英语的兴趣和信心，课堂上再也见不到往日的微笑和高举的小手。苏霍姆林斯基说：“成功带来的愉快是一股强大的情感力量，儿童想当一名好学生的愿望就是依靠这个力量。”每个儿童都渴望成功，渴望得到老师的表扬，哪怕只是一次微笑。这就需要在平时的教学中注重形成性评价，注意发现每个学生学习的潜能，让他们自主地参与活动，完成学习。

五、及时反思是提高课堂教学效率的保证。

教学反思是教师以自己的教学活动过程和课堂教学实践作为思考对象而进行全面、深入、冷静的思考和总结，对自己在教学活动过程和课堂教学实践中所作出的行为决策以及由此产生的结果进行审视和分析的过程。本人认为，每堂课后，及时认真的进行课堂反思，总结得失，是一种不断地优化课堂教学，提高课堂教学效果的很好办法。

总之，我们只要在教学中以灵活多变的教学方法吸引学生积极参与课堂活动，激发他们的学习兴趣，我们追求的小学英语课堂高效就会慢慢实现。所以，我们要在教学中不断摸索，在摸索中不断前进，为学生将来的学习奠定坚实的基础。

Be Grateful to Our Parents

Since we were born， many people help us a lot. We should be grateful to their kindness. But the ones we should show our greatest appreciation are our parents. From the first day we appear in their lives， they give us all their love and care， but never expect anything in return. As long as they are there， we do not feel any difficulties， because they are always in front of our shelter， preventing us from difficulties and danger. In order to make our lives better， learn better， they do everything they can to create the best conditions for us， but ignore their own needs. Therefore， we need to cherish parents’ love and repay their upbringing. We should treat them as they treat us.

Regardless of vacation for a few days, I must be with my family, only together with my family on holiday, is the true happiness.

Ill keep the spirit of the foot, to relax, and violin lessons to finish my homework, I hope to have a holiday, dont heart also worry about the homework, play, will be completely relaxed, no psychological pressure, can play very much.

Can you guess how? I will leave two days holiday, have a good at home doing nothing, have a good sleep, eat and sleep well, this holiday, is the most perfect period on the painting.

不管有几天的假期，我都一定要跟我的家人在一起，只有跟家人在一起的度假，才是真正的快乐。

我会先养足的精神，先放松自己，把功课和小提琴的功课都先完成，我希望放假的时候，不要心里面还担心这些功课，要玩，就要彻底放松，没有心理压力，才能玩得尽兴。

接着我们全家就搭飞机来到日本，第一站是迪士尼乐园，我决定要克服自己的胆小，所有的游乐设施都要玩，不管多么惊险，我都要勇敢的试试看。

然后我们来到北海道，住进一家开满樱花的民宿，放下行李后，好好的泡了舒服的温泉，带着甜蜜的微笑进入梦乡。

回国以前，我们参观了牧场，啜饮最新鲜的牛奶，买了数不清的纪念品，我打算带回来送给我的好朋友们，顺便也炫耀一下，让大家羡慕我的假期。

你猜怎的?我会留两天的假期，好好在家什么事也不做，好好补眠，好好的吃吃睡睡，这样的假期，才算是画上最完美的句点了。

In the things I have experienced, a lot of things are like rain, and soon disappeared, and only one thing is to make me excited.

That day, I went to the school to get a transcript, when the teacher announced my grades, my heart mentioned the throat, and other teachers say my grades, I scared almost dizzy. "Tian Zi Tong mathematics 99 points, language 106." When the teacher finished, the students for my results sounded a warm applause, because I was in our class count students, ranked on the top ten, and some in the upper Students are ranked below ten.

So, I heard the teachers announcement, tears. School, I am happy to hum the ditty, the tree like a bird singing for me, butterflies like to dance for me, the sun is very bright, like the light for me, I am happy that even the North can not find the , The name of all forgotten.

Come back home with my parents talking about my happy reason, my mother laughed from ear to ear, my father rewarded me ten yuan bonus, grandmother put up the thumb, grandfather said: "grandchildren really powerful, really furious. Tell me: "You go to the house to see the reward it!" I thought: "What will be rewarded? Can you be me?" I dumbfounded into the house, Wow! This is my dream computer And the computer desk! Solid wood computer desk with a black computer, how to see with, I am really happy, really want to jump to the universe at once.

This day is the happiest thing in my experience.
