the Interesting Work in My Job Today I'd like to introduce what I have been doing in my job. For many people software development is an interesing job and the developers are a group of intelligent people. Actually, it is not as difficult as expected. It just need that you think normally and you don't need to be a talent. My work runs around a SQL (Structured Query Language) language parser, which accepts a string containing a SQL sentence and parses it into a tree with many grammar nodes. I need add processing logics on these nodes. For example, if the sentence is "I am a boy", it will be parsed as a tree with a tree like below: Root Node(Sentence) / | \ ( I) (am) (a boy) Subject node Action Node Object node / \ a boy (Artical Node) (Noun node) To generate such a parsing tree, you need a parser first. You don't need write a parser by yourself since there are many free and open sourced parser generators. The one that I use is Antler, which was invented by a computer professor in an US university. The Antler tool let you create your own language parser and you just provide your grammar file complying with the writing rules. For instance, you write the following grammar file. Sentence: Subject Action Object ; Subject: Noun ; Action: Verb ； Object： Article？ Noun ； Noun: 'I' | 'He' | 'She' | 'boy' ; Verb: 'am‘ ; Article: a | A | the | The ; ......... With above grammar file, Antler compiles it and generates a parser for this specific language. "I am a boy" will be a valid sentence and parsed successfully.

How to better comprehend live broadcast One year ago, I started to listen live broadcast of BBC world service in BBC NEWS APP, a hour per day. It made some improvement in English speaking.

So I want to find a language partner to help me listen to BBC better, not just tell me a few tips, but involve in listening together with me. I don't know whether there is teacher to do such training.

Sunday, Oct 29th Today is Sunday. It is pretty cold and windy. The apartment I am living in is on the north side of the building so it has little time to be in sunshine. It makes my room feeling colder. In the whole last week, the weather is foggy and hardly to breath. Thanks for the north wind blowing fog off and I can enjoy the blue sky again. Yesterday I bought a gas mask online in order to resist the foggy days in the future. I rather wish I can use it less. One good news today is that my wife has won a free dinner award from a restaurant because she wrote many praising comments for the restaurant online. Each time she has a dinner there she always writes her feelings. We went there at noon and the dishes were very decorative and delicious. We ordered a roast duck, a ready-to-eat salad and a set of Beijing cake pieces, including green bean cake, red bean cake. The waiter served the roast duck and introduced how the duck slices were set on a big China plate, on which there was a peony. These slices formed four circles from inside to outside, the central one had one slice, then the next had 3, then 5 and 7. After we ate them all, more slices were served. The duck was too big for us. After lunch we went back home. My wife went to see a stage play and my daughter went for a training lesson of physics. I had an hour sleep and then I went for a walk in the park along the river nearby. Next, I got headache because tomorrow I will go to work and take a rush week again.

My commute I just changed my job a week ago. Now I go to office by cycling every day. I have to ride a long distance of 8 kilometers. It's a little bitter if I am riding on a bike in bad status. Since I ride on public sharing bikes, I need search a comfortable one here and there every morning. I can't ride my favorite expensive mountain bike because I have no safe place to park from thief. There are two main brands of sharing bikes here, Mobike and OFO bike, and other small brands, like BLUE bike. BlUE bike is the best of them for riding, easily pushing, quick and comfortable. But the amount of blue bikes is much fewer than that of the other two, which makes it very difficult to find. Also, the polluted foggy air here always annoys me when riding. It really ruins the happyness of riding. I dream that one day I can live in a place in clean air and under blue sky.

It's colder and colder, Oct 25th, 2017 It has been Autumn here yet and the day is becoming colder and colder. The day also becomes dark early, around 6PM. It is actually the law of nature reminding us to sleep eraly and have enough sleeping hours to keep being energetic. Today's good news that makes me very exciting is my application for online Chinese tutor passing through census successfully. That means I can take students from now. It's really a good day for me.

A book I've read recently: Homeless to Harvard Several days ago, I found a book that my daughter borrowed fron her class library. The book is titled 风雨哈佛路, and English name is Homeless to Harvard. It stayed on the shelf in my daughter's bedroom lonely. On the book covere it is a woman's pretty face. She must be a very beautiful and charming little girl when she was a child. I wanted to know her story. So I read it for days, going with joy and sadness that the girl had experienced long years before. Liz (her fore name Elizabeth) and her sister Lisa lived with their parents in a samll apartment in Bronx, New York city. Her dad and mother took drugs. Her family was much worse than poor. All money were used by mother to buy drugs. She and her older sister Lisa didn't have engough food and were in hunger every day. She had to go out to look for food and accomodation from her friends, some of whom were also children from poor single family. Sometimes she even stole food and clothing from supermarket stores. Even in such difficult condition, she still was grateful to her dad and mother. She loved them and worried about their health in her heart deeply, though she hated them at the same time. Fortunately, with some chances, Liz could make money by helping drivers oil their cars at a petrol station. With the earned money, she got a little confidence. In the following years she still fell into troubles like before. But she became more and more independent and strong in heart. One difficult moment was when she stayed with his boy friend in a motel. She had nothing and had to rely on the boy. The boy's secret was found by Liz. He often went out for drug. Liz had to make a choice, to ruin herslef with the boy together, or to leave him and start tough life by herself. The other diffcult time was when her mother died. She had worried about mother for many years because she had no way to save her mother from drug. Before her mother's death, she had been trying to find a high school to earn her a bright life. The interviews were also difficult for her. No high schools liked to accept such a poor, homeless girl of truancy. God helped her again. This time a great teacher, who had established a special high school to help those bad children in other people's eyes, gave a chance to her. She finished the study of high school and achieved the score of 40 points to graduate. She also won an award of $12000 from New York Times. The most exciting was that she was accepted by Harvard university.

My recitation of beginning paragraphs from rewrite version of The Call of the Wild. Buck did not read the newspaper. He did not know that trouble was coming for every big dog in California. Men had found gold in the Yukon. And these men wanted dogs to work in the cold and snow in the North. Buck lived in Mr. Miller's large house in the sunny Santa Clara valley. There were many gardens and fields of fruit trees around the house, and a river nearby. In a place like this, of course, there were many dogs. They were house dogs and farm dogs. But they were not important. Buck was the chief dog. He was born here and this was his place. Buck was four years old. And he weighed 60 kilos. He went swimming with Mr. Miller's sons, and walking with his daughters. He carried his grandchildren on his back, and sat on Mr. Miller's feet in front of fire in Winter. But this was 1897, and Buck did not know that men and dogs were hurrying to north-west Cannada to look for gold. And he also did not know that Manuel, one of Mr. Miller's gardeners, needed money for his large family. One night, when Mr. Miller was out, Manuel and buck left the gardern together. It was just an evening walk, Buck thought. No one saw them go, and only one man saw them arrived at the railway station. This man gave some money to Manuel.

My essay writting for IELTS taks 1 Give me a correction and rate it (1-9 band) if you like, that will help me know my real level for writing test. ========================================================================= You recently read an article in newspaper about someone you know personally. You found some information is wrong. Write a letter to editor to inform him about it. Use following points: What is the article about? What is the error? What you expect an editor to do? ========================================================================= Dear Sir, I am writing this letter to let you know about an error that I found in an article in the Beijing Times edited by you. A couple of days ago, in the morning, while I was reading the Beijing Times, I noticed an article titled Jack Ma - a great doctor in Ren Min Hospital. It seemed that the figure in the article was exactly my neighbor. That article introduced Jack Ma with many details, from his studying experience to his job career. Also, it talked about several cases how Jack Ma had been using his excellent operation skills to save lives of his patients. I was really moved by that article. This article was so good that I read through it without any break. After finishing the last word, I was pretty sure that it was exactly Jack Ma, who I had been known for many years. Jack Ma arrived to my community and became my neighbor ten years ago. We often met at each other’s home and talked about almost everything. So I know him with a lot of details. Though this article was almost perfect, there was still a little error about his hometown. A few weeks ago Jack Ma indeed told me that his hometown was Nanjing, instead of Beijing which was told in the article. Though it might be a trivial mistake, as an honest and loyal reader of your newspaper, I still want you to confirm it with Jack Ma and correct it if it is an error. I am looking forward to hearing from you soon. Best regards, Bill
