和David聊天 聊了近一小时，在前两次沟通时 就已经感觉自己很多东西 表达不出来，也就算了。尽力想听懂，大部分还明白，David说的好多词语我都听不懂，他是一个健谈者，at least I understand something. Hope it can be keep in memory for loon time.
I should practice IELTS topic when I walk around. Learn words related to the topic I am interested in like psychology. It would be hard, I have to try.
