I can tell you some elements of writing, but I can't help you write.

1。 Choose a composition you like first, and tell the general meaning (abbreviated) and what help your favorite composition has brought you. (detailed) own reading experience, (you can find similar compositions to imitate others' reading experience)

2. It is also the first time to talk about what experiments have been done and what difficulties have been encountered while doing the experiments. Write them all down.
