阅读表达 You may know the English letters A,B and C.But do you know there are people called ABC ? You may like eating bananas.But do you know there is such a thing as a 'banana person'? How strange! Are these people from 'another earth' ? No.They are just Chinese people like you and me. ABC means America-born Chinese.An ABC is a Chinese,but was born in the United States. Sometimes,people call an ABC a 'banana person'.A banana is yellow outside and white inside.So, when a person is a banana,he or she is white inside-thinking like a Westerner and yellow outside-looking like a Chinese.Do you know why? Usually,ABCs know little about China or the Chinese language.Some of them do not speak Chinese.Also,they are not interested in Chinese politics. But if ABC cannot speak Chinese,can we still call them Chinese people? Yes,of course.They are Chinese.They are overseas Chinese. These people may be citizens of another country, like the US, England or Canada,but they have Chinese blood.Their parents,grandparents or even great-grandparents were from China.They all have black eyes and black hair.But they are not Chinese citizens.They are not people of the People's Republic of China.For example,we all know the famous scientist C.N.Yang.He got the Noble Prize in 1957.Chinese people love him.But he is an American citizen. 根据短文内容,完成下列句子。 1.'ABC' in this passage means'_____________________'. 2.Chinese in Western countries are called 'banana persons'  because _____________________. 3.The underlined sentence means '______________________' in Chinese. 4.C.N.Yang is mentioned here to show that _______________________. 5.This passage mainly talks about ____________________.
