由于高中英语教学长期存在课时紧、教学任务重的情况, 在一个模块或单元结束时, 许多教师常忽视复习本模块或单元教学内容的环节。而学生也同样苦恼, 不少学生反映:学完一单元后, 感觉没有多大的收获。笔者认为, 导致这些问题的根本原因在于教师没有组织学生进行科学、有效的复习。

科学、有效的复习是知识向能力过渡的桥梁, 是启迪思考和开发智力的良机, 是提炼、升华教学内容, 帮助学生建构知识网络和提高学习兴趣的有效途径。就高中英语教学而言, 上好单元复习课, 对于学生巩固所学知识、提高语言能力有着事半功倍的作用。此外, 教师在上复习课时还能弥补之前教学中的欠缺, 提高教学质量 (马智慧、刘欢2011) 。

知识与技能目标:掌握有关绘画艺术的相关词汇、句型和知识;学习虚拟语气 (和现在、将来事实相反) 的用法;训练听力、阅读、写作技能。

情感、态度与价值观:培养学生对绘画艺术的兴趣。

(三) 教学片段

1. 回归内容

Scene 1:Lead in and show the task.To activate Ss and arouse them to talk about art.

(1) Pair work

(3) Group work

Fill in the blanks:

设计意图:通过欣赏图片引出话题;通过填空的方式复习本单元的重点词汇, 检查学生对相关词汇和知识的掌握情况, 了解学情。在学生完成活动的过程中, 教师不仅了解了学生的知识储备现状, 还能发现学生知识和技能方面的问题, 进一步明确了随后需要复习内容的重难点。

2. 突破难点

Scene 2:Practice

(1) 重点词汇和短语

realistic, abstract, religion, religious, sculpture, gallery, belief, consequent, consequently, aim, symbol, value, focus, possession, convince, impressionism, impressionist, shadow, ridiculous, nowadays, attempt, predict, the Renaissance, focus on, a great deal

(2) 重点句式

根据提示将下列句子翻译成英语。

(3) 那个男孩想熬夜看世界杯但被他的父母阻止了。 (attempt)

(4) 要是她会唱歌, 我就邀请她参加晚会了。 (if)

设计意图:外语学习的遗忘率通常较高, 在词汇学习方面尤为明显。学生学习词汇的最大障碍是如何实现词汇的高频再现, 从而加深理解、记忆, 以及如何完成词汇学习在课外的有效延伸。“突破难点”的活动就是要解决这个问题。为了帮助学生复习、巩固重点词汇和句型, 笔者设计的活动主要有翻译、填词、同义句转换等。

3. 弥补缺漏

Scene 3:同义句转换

例如:

(1) These years, Europe has changed a lot.

设计意图:弥补英语知识缺漏。教师要针对学生未掌握的内容进行矫正性学习, 弥补知识缺漏, 复习巩固尚未掌握的内容。教学内容的选择要考虑知识的深度与广度, 使其符合学生的需求, 使其适合所授班级的学生, 真正为学生创造学习的空间和机会, 让学生能够自主参与学习过程, 激发学生的学习潜能, 提高教学效率。

4. 语言运用

Scene 4:Group work

Please make up a small conversation between you and your partner.

(1) If you could have three of these paintings on the wall of your classroom, which would you choose?Discuss your reasons.These words might help you in your discussion:

(2) Would you rather have Chinese or Westernstyle paintings in your home?Give your reasons.

Scene 5:Writing

To learn to write letters for making suggestions.

英文建议信的写法:

建议信中应该包括建议的原因、理由和提出合理的建议。建议信的写作要简明扼要, 目的明确。

建议信的开头常用句式:

I am writing to express my view concerning...

You have asked me for my advice with regard to...and I will try to make some conductive suggestions.

表达建议常用句式:

I feel that it would be beneficial if...

I would recommend that...

As you may agree that...

建议信的结尾常用句式:

I would be ready to discuss this matter in further detail.

设计意图:复习教学中如何在“用”上下工夫, 提高复习教学的有效性, 教师要关注语言知识的运用, 凸显一个“用”字, 让学生实现知识向能力的有效转化。

结束语

本案例中的回归内容、突破难点、弥补缺漏、综合运用四个环节始终与“用”紧密相连, 分别体现在:学生在欣赏图片中走进话题, 教师在语言的运用中了解学生的原有知识的状况;师生在真实的语境中, 运用语言突破难点和重点, 消除盲点;学生在阅读中运用语言实现反馈和检测, 达到巩固语言和内化语言的目的;学生在运用语言中分析观察各种语言现象, 总结归纳语言学习的规律;学生运用语言解决日常生活中的实际问题。总之, “用”是复习的起点, 也是复习的终点。复习课中, 教师要在“用”上下工夫。

掌握课文中的重点句型的结构、用法

Unit 8 Sports

stand out（from）

辨析athlete与sportsman

athlete指运动员，从事体育运动的人，强调身体健硕的人。

如：He is real athlete. 他的实力真是名不虚传。

Sportsman也指运动员，但更强调职业，强调精神。

如：He is a real sportsman. 他才配是真正的运动员。

athletic adj. 健硕的，运动员般的

sportsmanlike adj. 有体育道德的，有风格的

gold adj. 金的，金制的 n. 金子

golden adj. 金子般的，金色的

辨析gold与golden

gold指金制的，如：gold watch，gold pen等

golden指金子般的，如：golden opportunity，golden hall，golden rules等

final n. 决赛

half / quarter final 半决赛/四分之一决赛

shoot v. 射击

shot n. 射击，投掷

would rather do than do 宁愿…也不愿…

辨析：join，join in，take part in与attend

join是become a member of的意思，即成为某组织的一员

如：He joined the Party three years ago.

join in是参加某活动之意，且此处亦可用join，且此处与take part in意义基本相同

Would you please join（in）/ take part in the game?

Would you like to join us in a walk?

attend则译为出席，一般指出席会议等。

如：He will attend the meeting.

competitor n. 竞技者，竞争者

compete v. 竞技，竞争

competitive adj. 竞争的，有竞争力的

competent adj. 胜任的，能干的，

如：Only skilled workers can do this job.

skillful的意思是熟练的，表现技巧的

如：He is a skillful musician.

gesture n. 手势，姿势 v. 摆姿势，做手势示意

（一）课文重难点

Every four years…

英语中表示“每…”用every…~s

如：每5天/每隔四天，every 5 days或every fifth day；

Many of the sports were the same as they are now.

比较状语从句中，as，than的后面的从句中用动词的不同时态表示与以前，过去及将来相比。

Some of the games in which the young men competed were……

介词+which的定语从句，注意此句中compete的用法。

They were held in Greece-the country in which the Games were born

注意：奥运会Olympic Games永远以复数形式出现

28 gold medals, ranking third of all the competing countries

注意：ranking在此处做伴随状语，注意rank的词组，rank sb. sth.（给某人定为…身份，头衔）和sb. rank sth.（某人处于…身份头衔）

Following the history-making success……

构词法，名词宾语+doing合成形容词

To make it the ever best Games……

注意此处的ever的用法和意义，此处用ever修饰最高级best，且此处的ever当永远，有史以来讲。这一点从ever构成的合成词中也可以见到，如：ever-green（长青的）

……will be preparing to light the Olympic torch to welcome……

将来进行时，表示将来某时正在做某事。

light sth. 点燃，注意light的形容词lighted和lit

首先它们都是light的过去式和过去分词，但它们作形容词时的用法不太相同，

如：The candle was lit/lighted.

a lighted candle

由此不难看出lit和lighted都可以用于表语，而只有lighted才能用于定语。

（二）WORKBOOK重难点

…France will be represented by three fencers.

注意represent一词，有“代表”的意思，且多用于被动语态。

Matches will be won or lost in a matter of seconds.

注意此句中matter的用法，matter有“事情，事情的核心”的意思，如：It’s not a matter of money, but a matter of time.
