(教材原句)On each stem are tw leaves, which are lng and narrw with a waxy texture.每根茎上有两片叶子，又长又窄，质地光滑。 [句式解构]　该主从复合句中主句部分使用了完全倒装； which引导非限制性定语从句，对leaves进行补充说明。完全倒装：完全倒装就是将谓语动词全部置于主语之前，主要有以下几种情况：(1)表示地点的介词短语＋不及物动词/系动词be＋主语(名词)❶In a lecture hall f a university in England sits a prfessr.在英国一所大学的讲堂里坐着一位教授。❷By the windw std a yung fellw with a badge in his hand.窗边站着一个年轻人，他的手里拿着一枚徽章。
(2)作表语的形容词/分词短语＋系动词be＋主语(名词)❸Present at the party are several cmpsers and gelgists.出席宴会的是几位作曲家和地质学家。❹Grwing all ver the muntain are wild flwers.漫山遍野都是野花。(3)表示方位/地点/时间的副词(in, ut, dwn, up, ff, away, here, there, nw, then等)＋不及物动词/系动词be＋主语(名词)❺Dwn came the rain and up went the umbrellas.下雨了，伞都撑起来了。❻Here cmes the bus.公共汽车来了。❼Nw cmes yur turn.现在轮到你了。
[名师点津]　在完全倒装句中，谓语动词的数要与后面主语的数保持一致。In frnt f the huse stands tw tall trees.(×)In frnt f the huse stand tw tall trees.(√)房前有两棵高树。

Step Ⅲ　Writing an bservatinal jurnal[文体介绍]观察描述类作文就是把观察到的事物按照时间或空间顺序描述出来。写作时要求内容真实，所见所闻要贴近自己的生活。写作前要细致观察，这样才能具体叙述，内容应包括被观察事物的外形、色彩、特点、动作等。写作时要突出中心，围绕一个内容、一种情景、一种感受进行写作，必要时结合自己的感受进行合理的想象，要有详有略、想象合理，写出新鲜感。
[写作要点](1)考虑好描写的视角和次序。视角就是我们通常所讲的人称，观察描述类作文用第一人称和第三人称都可以，但目的、内容和效果不同。描写次序是指先后顺序问题。一般来讲，观察描述类作文或是按空间顺序描写，或是按时间顺序描写。比如要描写植物生长的过程可按时间顺序，而描述一个房间时则需要按空间顺序。(2)写作时要选择重点部分或内容来写。无论描写什么都不可能面面俱到，要选择最能体现事物特征的一两点进行详细描述，比如植物的生长有一些关键期，如种子发芽、长出茎、长出第一片叶子等，这些都是最好记录下来的。(3)把描写和叙述结合起来。在写作中，描写通常需要与其他表达方式结合起来，尤其是常与叙述结合在一起。一般来说，描写是具体细致地描述客观事物，叙述是概括地描述事件的过程。
[常用表达]❶Yu'd better the sunlight.你最好把……放在阳光下。❷It's better fr yu t day.你最好每天都给……浇水。❸If yu take care f..., grw better and better.如果你照顾好……，……会长得越来越好。❹It cmes in a variety f clurs/shapes.它有各种各样的颜色/形状。
❺It cnsists f several integrated parts.它由几个互相关联的部分组成。❻It is shaped like a circle.它的形状像个圆。❼It is flat in shape and small in size.它形状扁平，体积小。❽ attached t the bttm.……与底部相连。
[实践应用]假定你是李华，老师让你根据下面的提示写一篇关于向日葵的观察日志。要点提示：1．把向日葵的种子埋在土壤里，然后浇水。2．一周后茎出来了。3．约三周后，花蕾长大了。注意：词数80左右。
第二步　遣词造句完成句子1．用1～2厘米厚的潮湿的土盖住向日葵的种子，然后定期浇水。(1)The sunflwer seed is cvered with 1～2 cm f mist sil __________________. (用并列句)(2)___________________________,the sunflwer seed is watered regularly. (过去分词作状语)
and is watered regularly
Cvered with 1～2 cm f mist sil
2．一周后，一根带着叶子和一个小花蕾的茎长出来，同时根继续向下长。(1)A week later, a single stem grws with leaves and a small flwer bud, ___________________________________________. (用并列句)(2)A week later, a single stem grws with leaves and a small flwer bud, ____________________________________________. (with的复合结构)
