写作技巧
如何写观察日志
1.写作指导
本单元写作项目是描写植物生长过程的观察日志。观察日志多是亲身经历和耳闻目睹的事情，所以要用第一人称来写；日志多是记述发生过的事情，因此常使用一般过去时，但使用时必须灵活掌握。日志应条理清楚，写出真实感。此外，应注意日志的格式，包括日期、星期和天气的书写位置。文章开头要表明写作目的，文章主体部分着重记录植物的成长过程，文章结尾记录作者的感受。
2.增分表达常用短语
growth conditions of the plant 植物的生长条件
a hole large enough 足够大的洞
put the earth back in the hole 把土放回洞里
up to 20 feet in length 长达20英尺
select proper seeds 选择合适的种子
a light application of fertilizer 轻施肥料

Use the garden cultivator to loosen the dirt all around the hole to make it easier for the roots to spread.用花园里的松土除草机把洞周围的泥土弄松，让根系更容易伸展。

One possible version:
Last summer I planted some mung beans in my garden.
First I bought some seeds and sowed them in the garden. A few days later, I went to the garden and found the mungbeans were beginning to come up. Another few days passed and the mung beans were coming into leaf. Now and then I sprinkled water on them so that they grew well.
My mung beans kept growing, and finally three months later they began to go to seed. I was very happy to see the fruits of my work.
