It is running around, looking for its next meal. With an angry cry, it opens its mouth, raises its beautiful feather-covered arms, and Wait, feathers on a dinosaur? For hundreds of years, people believed that dinosaurs looked like huge lizards. Just look at all those dinosaurs in books, films and TV shows! However, thanks to a piece of amber, scientists now know that this idea is wrong. In the amber from Southeast Asia, they found the tail of a dinosaur - with feathers. These beautiful golden stones quietly keep pieces of the past. They can tell us whether dinosaurs had feathers, but that's not all. They also help us understand that life on earth has always changed. A piece of amber from Northern Europe, for example, holds a flower. This species no longer grows in this area. But the find proves that it did 35 million years ago. In the future, amber may also help us discover if other species have changed over time. Thanks to amber, more than 300 unknown species have been discovered. In a piece of amber from Africa, scientists found 13 ants. Research shows that they are a completely new species. Scientists used to believe that ants came from the northern half of the earth. The discovery of this African species has changed old beliefs about the history of ants. Who knows whether this piece of amber will tell us more secrets? As a window on the past, amber has been much studied. However, it's still not fully understood. We should put more effort into research. Then we can use this key to unlock more secrets of nature. 二、重点词汇 英文 音标 词性 中文释义 dinosaur / da n s / n. 恐龙 feather / fe / n. 羽毛,翎 feather-covered / fe k v d/ adj. 羽毛覆盖的 lizard / l z d/ n. 蜥蜴 amber / mb / n. 琥珀 whether / we / conj. 是否(用于表示选择或对某事不确定) northern / n n/ adj. 北部的 species / spi i z/ n. 物种 unknown / n n n/ adj. 不知道的,未知的 African / fr k n/ adj. 非洲的;非洲人的 belief /b li f/ n. 观点 fully / f lli/ adv. 完全地;充分地;彻底地 unlock / n l k/ v. 揭开 newspaper / nju z pe p / n. 报(纸) writing / ra t / n. 写作,著书 style /sta l/ n. 风格 method / me d/ n. 方法,办法 text /tekst/ n. 文字材料 alive / la v/ adj. 有活力的,有生气的 argument / j m nt/ n. 论点,论据 board /b d/ n. 布告牌,公告牌 model / m dl/ n. 模型 planet / pl n t/ n. 行星 clear /kl / v. 清除;清理 upload / p l d/ v. 上载,上传 whale /we l/ n. 鲸 boiling / b l / adj. 很热的,滚烫的 chemical / kem kl/ n. 化学品 endless / endl s/ adj. 无数的;无限的 sight /sa t/ n. 视力,视觉 anybody / enib di/ pron. 任何人 magnifier / m n fa / n. 放大镜 wealth /wel / n. 财富 hardly / h dli/ adv. 几乎不 belong /b l / v. 应在(某处) granddaughter / r n d t / n. 孙女;外孙女 三、重点短语 英文短语 中文释义 unlock the secrets of sth 揭开某事的秘密 belong to 属于 thanks to 多亏;由于 no longer 不再 over time 随着时间推移 used to do sth 过去常常做某事 put more effort into 把更多精力投入到 a window on the past 了解过去的窗口 look for 寻找 for example 例如 change old beliefs 改变旧观念 a piece of amber 一块琥珀 四、重点句型/语法 句型/语法点 中文说明 例句 that 引导的宾语从句 谓语动词表示肯定的概念(希望、相信、知道、说等)时,从句一般用 that 引导;that 没有词汇意义,多数情况下可省略。 I believe (that) we shall become good friends. whether / if 引导的宾语从句 表达“是否”这种不确定的概念时,从句用 whether 或 if 引导。 They can tell us whether dinosaurs had feathers, but that's not all. used to do sth 意为“过去常常做某事”(现在不再)。 Scientists used to believe that ants came from the northern half of the earth. thanks to 意为“多亏;由于”。 Thanks to amber, more than 300 unknown species have been discovered. 五、重难点突破(宾语从句(1):that 与 whether / if 引导的宾语从句) 语法要点速记 要点 说明 例句 ① 什么是宾语从句 放在动词后面作宾语的句子叫宾语从句。宾语从句分为三类:that 引导、whether / if 引导、疑问词引导(本单元学习前两类)。(教材附录 Guide to the language use) ② that 引导的宾语从句 当谓语动词表示肯定的概念(希望、相信、知道、说等)时,从句一般用 that 引导;that 没有词汇意义,多数情况下可以省略。常接 that 从句的动词:believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish。例:I believe (that) we shall become good friends. ③ whether / if 引导的宾语从句 表达“他不知道他们周六是否会去植树”这类不确定的概念时,从句用 whether 或 if 引导。课本原句:They can tell us whether dinosaurs had feathers. ④ whether 与 if 的选择 两者在宾语从句中常可互换,但与 or not 直接连用时用 whether(whether or not);正式文体中 whether 更稳妥。 ⑤ 本单元易错点 1) 从句误用疑问语序( I believe that will he come that he will come);2) that 与 what 混淆(that 无词汇意义,what 在从句中充当成分);3) 表“是否”且句中有 or not 时误用 if。 易混辨析(中考易错) 词 A / 释义 词 B / 释义 辨析与例句 whether conj. 是否(可与 or not 连用,更正式):They can tell us whether dinosaurs had feathers.(课本原句) if conj. 是否(口语常用,不能直接与 or not 连用) I wonder if / whether the story is true. 但 I wonder whether or not it is true. 只能用 whether。 alive adj. 有活力的,有生气的(多作表语或后置定语) living adj. 活着的(多作前置定语) making the text alive 使文字生动(教材 Learning to learn 原句);living things 生物。 语音聚焦(锚定本单元单词重音) 音标 说明与语篇例词 动名重音移位 同一拼写的词重音不同、词性不同:record / rek d/ n. 记录(a world record) /r k d/ v. 记录;produce / pr dju s/ n. 农产品 /pr dju s/ v. 生产;desert / dez t/ n. 沙漠 /d z t/ v. 抛弃(本单元语音聚焦 Stress in words (1):重音在第二音节通常是动词)。 六、学习锦囊(易错音标 中考链接 记忆口诀) 学习锦囊(易错 中考 口诀) 易错音标 species / spi i z/ 词尾是 /i z/ 勿读成 /s/;feather / fe / 词中是浊辅音 / /,勿读成清辅音 / /(whether 同理);amber / mb / 词中 /mb/ 连缀勿漏 /b/。均出自本单元词表。 中考链接 宾语从句引导词是中考单选与补全对话高频考点:陈述内容用 that(常可省略),表“是否”用 if / whether(与 or not 连用时用 whether)。从句永远用陈述语序,如 I believe (that) we shall become good friends. 记忆口诀 琥珀是 a window on the past(了解过去的窗口)。课文三大高频短语:thanks to(多亏)、no longer(不再)、used to(过去常常)——考古发现类说明文一把抓。 第二部分 默写部分(掩卷自测) 一、语篇挖空(根据课文原文填空,每空一词) Imagine a dinosaur in an ancient forest.
