雅思阅读的no和notgiven到底怎么区别

no就是与原文不符，有冲突的；not given是没有依据的，不能直接说是错的；举个例子：
原文：Julian is a Chinese girl and she does well in English. In her college, she also learned some other foreign languages and she is always a good language learner.
题目：
1. Julian is from an Asian country.
2. Julian, the Japanese girl, has a good command of English.
3. Julian may also learn Spanish well.
4. Chinese girls are all good at English.
对于上面几个题目，1肯定是对的；2明显与原文有冲突，原文说人家是中国人，题目里说人家是日本人，所以就比较明显了；3说Julian可能西班牙语学的也不错，从原文中“she also learned some other foreign language and she is always a good language learner”似乎感觉这个说法是对的，但是没有依据，只是说她学过外语，学外语有天赋，但并没有提到西班牙语，所以这个不能算错，只是文中并没有提及而已，是没有有依据的，所以第3题就是NOT GIVEN; 同样，第4题说“中国女孩都擅长英语”完全没有依据的，所以就是NOT GIVEN; 不要凭感觉去才，要找到依据才行。
Is all above made clear to you?
