Strawberries are many people's favourite fruit and some people even want to plant strawberries by themselves.Actually，the growth process of them is pretty long.Here is my observation about them.

The leaves of the seedlings gradually grow into larger umbrella­shaped ones after they have been planted in the soil for two weeks.One month later，small buds begin to appear.The following process is a little longer，taking about two months for the pistils to grow into real strawberries.And five days later，we can have fresh mature strawberries.

Isn't it interesting to watch the growth process?

【参考范文】

Last summer I planted some mung in my garden.

First I bought some seeds from a seedman.Then I sowed them in the garden.A few days later，I went to the garden and found the mung were beginning to come up.Another few days passed and the mung were coming into leaf.Now and then I sprinkled water on them so that they grew well.

The mung I planted kept growing，and finally three months later they began to go to seed.I was very happy to see the fruits of my work.
