How do you say“我知道他，但我不认识他” in English? 汉语里知道和认识是两个不同的词，但英语里好像都是用“know”。那么下面这两句话怎么用英文表达呢？ 1、我知道他（我们一个学校的），但我不认识他。 2、我认识他，但不怎么熟。

what difference between technical and technological? It would be great if you can give me some examples. Thank you so much!

Learn More Culture Background For a English learner, I think the most difficult thing for listening comprehension are News Report and Stand Up Show. Do you agree with me? The News Report is difficult because the news is often written in a very serious way and use many big words. To understand it well you must have a huge vocabulary. The difficult part of Stand Up Show is the camedian usually speak very fast with some certain lilarious way. And the more difficult thing is even you can understand exact every sentence they say and you hear the audence brust to laugh, chances are you still might not understant what is so funny. Because you have no idea about the background stories which make the audence laugh. That's what I think the most difficult part of learning a language--The Culture Background.

My Daughter's Pet My 12-year-old daughter is reading Roald Dahl's book ESIO TROT for practice Enghlish reading. I promised to buy her a tortoise as a reward if she finish the book herself. She haven't had any pet before. She likes small animals, but she is allergic to cat hair, so she can't keep any cat or dog, but a tortoise is safe for her. So when I told her this, she was very happy!

The GPS system Today I drived to a village very far from the city I lived. I was going to visit several different destinations in there. But in one place, my phone's GPS system suddenly not working. It kept searching and recalculate. I spent a lot of time but it seemed that I was further and further to my destination. So I had to call the person lived in there to lead me on the phone. But to make things worse, maybe because my phone worked too hard, it soon out of power! Finally, I stopped my car occasionally and asked the people on the road to help me out. That was a terrible experience! Everyday we use many apps on our phone, they help us a lot and make our life much more convenient. But can you imagine one day if you have to live without all these apps, even without your phone, what kind of life it would be?
