一、审题定调
本写作任务要求写一篇观察日记，属于描写文的范畴。写作时应注意以下几点：首先，应按照一定的逻辑顺序，这样才能层次清楚，有条不紊；其次，描写时要抓住所写植物与其它植物的不同点，突出其特点。
此外，人称主要用第一人称和第三人称，时态主要用一般过去时。
二、谋篇布局
本写作可分为三部分：
第一部分：向日葵的栽种过程；
第二部分：向日葵的生长过程；
第三部分：自己的感受。
1. 认真观察，抓住特点。观察的重点是植物的干、枝、叶、花及颜色，了解它们的大小、高矮、形状、色彩、味道等。还要抓住特点，有目的地观察。如植物开花时的姿态、颜色、花期；植物叶子在不同时间、不同季节的变化。总之，要抓住所写的植物与其它植物的不同，写出它的特点。
2. 按一定顺序写。可以先从整体入手，看它像什么，然后再一部分一部分地写。也可以按照它生长的时间顺序写，先长什么、再长什么，最后长什么；也可以按根、茎、叶、花、果实的顺序写。总之，要按一定的顺序写，这样作文才层次清楚，有条不紊。
3. 表达自己喜爱的感情。尽可能地写出所见、所闻、所感。
三、写作要领
四、注意事项
1. 观察日记一般使用第一人称，时态可用一般现在时和一般过去时。
2. 写作时要遵循一定的顺序，可按照时间顺序，在描述写植物的具体细节时可从下到上(根部、茎部、叶子、花朵)进行描写。

Now write your observational journal about the sunflower.
An observational journal about the sunflower
1 June
Covered with 1-2 cm of moist soil, the sunflower seed takes a few days to come up after being planted. Water has been added regularly and the hard seed coat softens in the damp soil to allow the first root to pierce downwards and the first leaves to push to the soil surface.
6 July
The root continues to grow downwards. The single stem grows hollow and smooth, revealing large spade-shaped leaves from the growing tip. Gradually, the plant’s growing tip reveals the first hints of development of the flower bud. The plant stem becomes more woody.
26 July
About three weeks after the flower bud first becomes visible at the tip of the sunflower stem. It enlarges and begins to reveal a flattened disc. Over the course of one week, the yellow ray florets, the disc florets bloom across the core of the sunflower blossom. It is yellow, looking beautiful.
