The interesting expressions i find these days(Oct 22th Monday) 1.out of the blue(if I translate literally in Chinese,that is 从蓝色中出来） I know it's the English slang.=by accident /chance..... 2.out of the world(走出这个世界）what i think helps me memorize this phrase is when u see something new, just take it with a peculiar vision beyond the world,u will feel "wow,that's wonderful/excellent/brilliant/marvellous/terrific/super(pretty) good./awesome/fantastic/gorgeous/splendid...or that's the cat's meow~~ eg.Today i met an old friend out of the blue,and she treated me to a square meal.The food is so delicious and out of the world I think ,making me feel as if I were flying in the paradise...(of couse this is the story i make up just for consolidating what I have learned today...)but I indeed resolved to be a foodie.lol.. By the way ,what kind of food do you like ?As for me ,it's countless for i am unable to resist the temptation of cuisine..(please correct my errors or write down your ideas.i am looking forward to it~thank u ~\(≧▽≦)/~）
