一段中文 翻译成英文《1》通过这次调查问卷我总共访问了30人，其中男女各占50%，这样男女比例平均分布，不会降低研究的代

In this questionnaire， I visited 30 people in all, males and females of whom respectively covered 50%. Thus the proportions of men amd women were averagely distributed, which will not reduce the representiveness of research. This interview basically concerned the passers-by in the streets at different ages. I chose to question ten young people, ten middle-aged people and ten old people. I wanted to distribute the people on average according to their different ages so as to raise the representiveness of this questionnaire. Most of them, which occupied 40%, come from China, 30% from America and the rest of them from India. Japan and Brazil occupied 25% on the whole. As this research mainly aimed at China ang America, the Chinese and Americans took up a comparative proportion, which is comparatively relevant to the research theme.
