Prepare for tomorrow's speech.

Tomorrow morning, I will give two speech, search and causal relation extraction. But I have not prepared for the speech of search.

So today for me is very busy.

Before some days I had read the paper many times and I had written the paper review outline. But when I was doing the ppt for this paper, I found out that I must read this paper for more times.

Right now I began to understand the old sentence that you will fully understand the book after you have read it 100 times.
