I have studied Google syntax when I was in senior high school. Google syntax has a lot of syntax, like ""、site、related and *. I didn't use it because I thought it just for exam. Through the class this week, I am surprised at google syntax. I didn't know that google syntax is such useful. When I put * in the sentence, I can know phrase and preposition. When I type site, I can search information in website which I define it.
