Joe: I think they're oceans. (地球表面构成) Ms Guo: Yes, they are. The Earth was very clean and beautiful in the past, but now some parts are dirty. Can we do anything to help the Earth? (地球的过去与现在) Alice: Yes. We should stop throwing rubbish into rivers. (帮助地球的具体建议1) Peter: We should stop cutting down so many trees. (帮助地球的具体建议2) Kitty: We should stop using plastic bags. (帮助地球的具体建议3) 02 写作方法指引-递进式结构法 1.引入:通过 “识别地球图片” 开启话题,自然过渡到地球表面构成的介绍 2.转折:对比地球过去与现在的状态,指出 “部分区域变脏” 的问题,引发保护需求 3.主体:呈现不同人物提出的保护建议,提供具体行动方向 4.收尾:可围绕 “践行建议、共同护球” 升华主题,强调保护地球的意义 03写作方法指引-示例写作方法指引-示例 Look at this picture. It is the Earth, our home.(引入主题:地球) The green and brown parts of the Earth are forests and land. The blue parts are oceans.(地球表面构成) In the past, the Earth was very clean and beautiful. But now, some parts of it are dirty. We must do something to help it.(地球的过去与现在) We should stop throwing rubbish into rivers. We should also stop cutting down so many trees. And we should stop using plastic bags too.(帮助地球的具体建议) Let’s work together to make the Earth clean again!(呼吁行动) 01 基础知识精讲-句型 1. 描述事物构成与特征 参考单词: Earth(地球);forest(森林);land(陆地);ocean(海洋);clean(干净的);beautiful(美丽的);dirty(脏的) 参考词组: the green and brown parts(绿色和棕色部分);in the past(在过去);now(现在) 参考句型: 1. The ... parts of ... are ...(…… 的…… 部分是……) 2. ... was/were ... in the past, but now ... is/are ...(…… 过去是……,但现在…… 是……) 3. It is ...(它是……) 2. 提出建议 参考单词: stop(停止);throw(扔);cut(砍);use(使用);should(应该) 参考词组: throw rubbish into rivers(向河流扔垃圾);cut down trees(砍伐树木);use plastic bags(使用塑料袋);stop doing sth.(停止做某事) 参考句型: 1.We should stop ...(我们应该停止……) 2.We should ... to help ...(我们应该…… 来帮助……) 3.Let’s ... to make ...(让我们…… 来使……) 02 语法 一般过去时与一般现在时的对比运用: 1.含义:通过对比过去和现在的状态,突出事物的变化,一般过去时表示过去的状态(常与 “in the past” 连用),一般现在时表示现在的状态(常与 “now” 连用)。 2.用法示例: 一般过去时(描述过去状态):The Earth was very clean and beautiful in the past.(地球过去非常干净美丽。) 一般现在时(描述现在状态):But now some parts of the Earth are dirty.(但现在地球的一些部分变脏了。) 动词形式变化:be 动词的过去式为 “was/were”(单数用 was,复数用 were),一般现在时 be 动词为 “is/are”(单数用 is,复数用 are);实义动词过去式需根据规则变化(如 “clean” 过去式为 “cleaned”,但此处描述状态用 be 动词更常用)。 提分练 一、选择题 ( ) 1. The green parts of the Earth ______ forests in the past, and they ______ still forests now. A. was; are B. were; are C. were; was D. are; were ( ) 2. We ______ throw rubbish into rivers. We should keep rivers clean. A. should B. shouldn't C. can D. can't ( ) 3. Ms Guo ______ us a picture of the Earth yesterday, and she ______ us about its parts now. A. shows; tells B. showed; told C. showed; is telling D. shows; is telling (二)用所给单词的适当形式填空 1.The Earth ______ (be) clean and beautiful in the past. But now it ______ (be) not so clean. 2.We should stop ______ (cut) down too many trees. Trees are important for us. 3.She ______ (tell) me about the oceans last week. Now she ______ (teach) me more about the Earth. (三)按要求改写句子 1. The blue parts of the Earth are oceans.(改为一般疑问句) 0. The Earth was clean in the past.(改为否定句) 0. We should stop using plastic bags.(对划线部分提问) 参考解析 一、选择题 1.答案:B 解析:第一空 “in the past” 表明用一般过去时,“the green parts” 是复数,be 动词用 were;第二空 “now” 表明用一般现在时,主语 “they” 是复数,be 动词用 are,所以选 B。 2.答案:B 解析:根据后句 “我们应该保持河流干净”,可知前句表示 “我们不应该向河流扔垃圾”,“不应该” 用 shouldn't,A 选项 should(应该)与句意相反,C 选项 can(能)、D 选项 can't(不能)均不符合建议语境,所以选 B。 3.答案:C 解析:第一空 “yesterday” 表明用一般过去时,show 的过去式是 showed;第二空 “now” 表明用现在进行时,结构为 “be + 动词现在分词”,主语 “she” 是第三人称单数,be 动词用 is,teach 的现在分词是 teaching,所以选 C。 二、用所给单词的适当形式填空 1.答案:was; is. 解析:第一空 “in the past” 表示过去,主语 “The Earth” 是单数,be 动词用 was;第二空 “now” 表示现在,主语 “it” 是单数,be 动词用 is。 2.答案:cutting. 解析:“stop doing sth.” 是固定搭配,意为 “停止做某事”,所以填 cut 的现在分词形式 cutting。 3.答案:told; is teaching. 解析:第一空 “last week” 表示过去,tell 的过去式是 told;第二空 “now” 表示现在进行时,主语 “she” 是第三人称单数,be 动词用 is,teach 的现在分词是 teaching。 三、按要求改写句子 1.答案:Are the blue parts of the Earth oceans? 解析:原句是一般现在时的肯定句,be 动词是 are,改为一般疑问句时,将 are 提到句首,首字母大写,其余部分不变。 2.答案:The Earth wasn't clean in the past. 解析:原句是一般过去时的肯定句,be 动词是 was,改为否定句时,在 was 后加 not,缩写为 wasn't。 3.答案:What should we stop doing? 解析:划线部分 “using plastic bags” 表示 “做的事情”,对其提问用特殊疑问词 what,原句含有情态动词 should,将 should 提到主语 we 前,“停止做某事” 用 “stop doing”,所以问句为 “What should we stop doing?”。 模拟写作提升1 请根据对话内容,以 “Our Earth, Our Home” 为题写一篇作文,介绍地球的构成、现状以及我们能为地球做的事。 要求: 1.书写规范,正确使用标点符号。 2.语言表达流畅。 3.不少于 50 词。 参考词组: our home(我们的家);look after(照顾);work together(一起努力);make...clean(使…… 干净) 参考句型: 1.The Earth is our home.
