IELTS speaking Hello! My name is Hollis and I am about to take the IELTS speaking test in a month. Last time I got the speaking score at 7. And I want to get improved and a higher score this time. If you also want to improve speaking in English or you also have a speaking test soon, maybe we can practice together once a week or something. My problem in speaking was the lack of variety of vocabulary, especially for the topic I am not familiar with. I guess it’s partially knowledge problems. Grammar was never 100% when i spoke. But I think the more we speak, the more fluent we are. If you are interested in topic based practice, please let me know:) Thank you :)

Some thoughts These days I keep feeling that people are all lonely at some point. I could be really busy from Monday to Friday, and sometimes I have work to do during weekends. But does this add value to me? Do I know what I am passionate about? When everything settles down, I feel very sad that I always don't have time for some good rest.

Practice_3 When I stepped into office and just put down my bag this morning, my colleague looked at me excitedly with some expectations. And then he told me an interesting story about how he got his phone back on the subway after he almost thought it’s the worst day of his life. On his way to office, he heard the sound of the metro and he knew he had to catch up this time. Unfortunately, his phone jumped out of his pocket when he was running and narrowly escaped from being smashed by the door. The situation was quite dramatic, he’s inside the underground and his phone was one the ground outside. There was an old warmhearted man who happened to stand next to him and knew what’s going on here, suddenly he made a call to his son who’s still waiting for the subway at the station where he dropped his phone and told him to pick it up. Above is a wonderful story. I have to admit that life is always full of unexpected surprise which you can never find in any movie.
