【原创教学】人教版新教材必修二Unit Two Wildlife ProtectionReading and Thinking一、课例背景1. 文本解读本课例选自人教版高中新教材必修二Unit2 Reading and Thinking —— Wildlife Protection。

本单元的中心话题是目前全世界都相当关注和重视的野生动物的保护。

该主题语境属于三大主题语境“人与自我、人与社会、人与自然”中的“人与自然”这一大类，并从属于该语境下“环境保护”主题群。

该主题语境为语言学习提供了有关人与自然、人与动植物的意义语境，并有机渗透情感、态度和价值观。

众所周知，自然界是一个复杂的生态系统，生存其中的动植物之间存在着微妙的平衡关系。

任何一个物种的灭绝都会对这种平衡产生影响，大规模的物种灭绝会对生态系统产生严重甚至不可逆转的影响，由此会造成巨大的损失。

因此，保护野生动植物和人类可持续发展息息相关，正如文中志愿者扎西所言，保护野生动植物就是保护人类自己，也是保护人类赖以生存的星球。

在处理文本的过程中，笔者用人类和自然两条线贯穿全文，人类线以扎西视角代入我的意识，然后从个体上升到群体，最终上升为整个人类；自然线以藏羚羊为切入点，引出野生动植物，在进一步扩展为自然，最终落脚点为整个星球，然后将两条线索串联在一起，构成了人与自然的和谐统一，即：Zhaxi I We Human beingsHarmonyTibetan antelope wildlife nature planet2. 课型解读本课例所涉及的板块课型是Reading and Thinking，本板块的活动主题是“学习保护濒危动物”，主要讲述了我国保护珍稀野生动物藏羚羊的措施和取得的成就。

阅读文本“A Day in the Clouds”通过介绍藏羚羊过去和现在的生存环境，倡导每个个体通过自身生活方式的改变，学会与自然、野生动植物和睦相处，学会保护、尊重野生动植物，以此来消除人类对野生动植物存在的威胁，最终达成人和自然的和谐共生。

2019-2020学年新人教版高中英语必修2语法填空学案：Unit 3 2

Unit 3 Section ⅡⅠ.单句语法填空1．(重庆高考改编) In my hometown，there is always a harvest supper for the farmers after all the wheat_has been cut__(cut)．解析：考查动词的时态和语态。

句意：在我的家乡，麦子丰收过后农民会有一个庆祝晚餐。

现在完成时表示动作已经完成，才会举行庆祝活动，而且wheat与cut之间构成逻辑上的动宾关系，所以用被动语态。

2．—Is the meeting being held now?—No.I hear that it_has been put__(put) off till tomorrow.解析：考查动词的时态和语态。

答语句意：我听说会议已推迟到明天了。

put off“推迟”，与meeting之间为被动关系。

会议现在已被推迟，故用现在完成时的被动语态。

由时间状语up to now可知应用现在完成时。

means为单复数同形的单词，由其前的all可知此处作复数名词。

4．—Your English is very good.—I'm still nervous.After all，it is only the second time that I_have met__(meet) foreign guests.解析：考查时态。

该题考查“It is the＋序数词＋time＋that从句”这一句型中的时态，该句型中that从句的时态用现在完成时。
