He was also an inventor... Moreover, Franklin was a scientist...——He is a printer, a writer, an inventor and a scientist. 朗读规则与示例表; 读 Franklin 短文圈出四个身份词并对照词根。 参考答案:printer=print+er;inventor=invent+or;tourist=tour+ist;writer=write+er;scientist=science+ist 三后缀详解 Suffix analysis ①-er 最常用:加在动词或名词后表职业或行为者——teacher(teach)、driver(drive)、farmer(farm);也可作比较级(taller、faster)。②-or:多源自拉丁语动词词根,强调专业性身份——actor(act)、inventor(invent);部分词可指工具或抽象功能——conductor(导体/指挥)、detector(探测器)。 ③-ist:表示职业或专业身份,强调专业性或系统知识——scientist(science)、violinist(violin);也可表理念或信仰——socialist、nationalist。 归纳领地分工:-er「大众款」动词直接加、-or「专业款」、-ist「学术款」。 按领地分类整理三后缀高频词; 辨析 -er 作身份词与作比较级的两种用法。 十词转换 Word building Change the following words into nouns for people by adding the suffixes -er, -or and -ist:1 plan→planner(双写 n)2 own→owner 3 art→artist 4 win→winner(双写 n)5 write→writer(去 e)6 piano→pianist 7 biology→biologist(y 变 i)8 visit→visitor 9 publish→publisher 10 manage→manager(去 e) 点破:十词四类变化——直接加(owner/artist/visitor/publisher)、双写(planner/winner)、去 e(writer/manager)、y 变 i(biologist)。「一元一辅」夹中间就双写。 独立完成十词转换; 按四类变化给每个词贴标签; 归纳「一元一辅双写」的判断口诀。 参考答案:1. planner 2. owner 3. artist 4. winner 5. writer 6. pianist 7. biologist 8. visitor 9. publisher 10. manager 头脑风暴 Brainstorm Can you brainstorm as many words ending in -er, -or and -ist as possible?——-er: farmer, driver, gardener...;-or: director, actor, editor...;-ist: journalist, chemist, physicist... 小组竞赛:每组认领一个后缀,两分钟内写词最多且拼写正确者胜,写完按「直接加/拼写变化」贴标签。 分组头脑风暴扩充词库; 按拼写类型给新词分类。 slashie 语篇六空 Contextual practice Amy is asking Mr Wu about the meaning of "slashie". Complete what Mr Wu says:A slashie is someone good at many different jobs. Xiao Yi is a great (1) designer (design). He's also a (2) singer (sing) and (3) dancer (dance). Liang Xu is a (4) biologist (biology). She's also an amazing (5) photographer (photograph) and (6) writer (write). Today, there are more and more chances for people to develop their interests in different areas. So, we'll see even more slashies in the future. 点破:六空全走「a/an+身份词」结构——dancer 去 e、biologist y 变 i、photographer 重音在 to 拼写别丢 o。 理解 slashie(斜杠青年)含义; 独立完成六空并核对; 说出每空的拼写变化类型。 参考答案:(1) designer (2) singer (3) dancer (4) biologist (5) photographer (6) writer 写伟大学习者 Writing Write about great learners you know, using the suffixes -er, -or and -ist. 三例:①Marie Curie——a famous scientist, both a physicist and a chemist, the first woman to win a Nobel Prize, also a great educator for women in science. ②Yuan Longping——a Chinese scientist known as the "Father of Hybrid Rice"(杂交水稻之父), also a teacher and a professor at university, his work helped China and many other countries feed more people, but in his heart he considered himself as a farmer. ③Lin Huiyin——a famous Chinese architect and writer, helped design many beautiful buildings and also wrote lovely poems and stories. 指导:每句至少放一个身份词,后缀词作「身份证句」的主语补足语。 朗读三例并圈出所有身份词; 仿写一位伟大学习者(每句含至少一个 -er/-or/-ist 身份词)。 参考答案:示例见 activity:Curie——scientist/physicist/chemist/educator;Yuan——scientist/teacher/professor/farmer;Lin——architect/writer 语言点精讲 Language points ①A printer prints books and newspapers. An inventor invents new things. A tourist visits places for pleasure. 印刷工印刷书籍和报纸。发明家发明新事物。游客为了乐趣而游览各地。——三个后缀加在动词或名词后构成表「人」的名词:-er 最常用,直接加(teach→teacher)、去 e(dance→dancer)、双写(win→winner);-or 多用于 -t、-te、-ct、-ss 结尾动词(invent→inventor; visit→visitor),manager 属固定搭配需单独记;-ist 常加在学科、艺术或乐器类名词后(piano→pianist; science→scientist; art→artist)。 ②win→winner; dance→dancer; piano→pianist; science→scientist——三条核心拼写规则:①重读闭音节且末尾只有一个辅音字母时双写该辅音再加后缀(win-n-er);②以不发音的 e 结尾时先去掉 e 再加后缀(danc-er、scienc-ist);③以 -o 结尾的乐器/学科词直接加 -ist(pian-ist),注意个别例外。 两组语言点逐组理解并自测拼写; 熟记:三后缀三分领地;拼写三规则(双写/去 e/直接加); 用检测题反向验证。 随堂检测 Testing 完成随堂检测:教师发放随堂检测题,学生限时独立完成后,教师逐题核对讲评。 【一、单项选择】 1.
