How the USPS Works
Every day about seven billion people would send the snail mail. Every afternoon they will collect all the mails and the boxes. First step is to separate them. The boxes go one way. The flat envelopes go other way and thick envelopes go somewhere else. There is a special machine which can sieve the thick envelope out. The next step is to bar code them. Every envelope has their unique code. It is like the ID for the letter. Then the computer would read the front of the envelopes’ address. The computer can tell the zip code and classify the envelopes. Finally, the local mails go to the particular post office. The other mails go to the plane or some other places.
I usually send the mails by USPS; however I had never seen this working process in the post office. I admire the computer can classify the letter by the zip code. The computer can deal with millions mails. It is really amazing. When I saw amount of letters in the post factory, I knew that the automatic computer is really important. If the post offices just have the people to handle the mails, I would take much time to send the mails.

Week 6: Task 1 - Long Term Memory
The first video is a crazy guy introduced the long term memory. He said that long term memory is like a file in the computer. There are two types of long term memory: Procedural memory and Declarative memory. Procedural memory is the memory you doing something such as backing a cake. There are two parts of Procedural memory. First is episode which is like life. Second is Semantic memory that you learning at school and playing games.
The second video is a woman introduced that there are four ways to help long term retrieval. First, you have to repeat recite and review. She teaches “Mississippi” to two people. You have to listen and speak the spelling in order to remember the word. The second way of them is distributive practice. You can divide the word to memory. The third way is serial position effect. Finally, you have to find the similarities and differences. You can learn fast by using common word to help your memory.
I prefer the second video. I learn the long term memory due to the women introduced the detail. She talks the clear steps and ways. The last way she taught that make me feel amazing. I haven’t heard that way to memorize. I will try to do this in my studying.
Recite- to say a poem, piece of literature etc that you have learned, for people to listen to
