No one can denythat the collected information qualitywill greatly rely on one's English proficiency under the backgroud of globalization. If you just want to getdomestic information, maybe it's unnecesary for youtomaster any foreign languages. However, nowadays, even many Chinese publish their papers in English in order to let their papers known by more people all over the world. Some researchers only have their papers published on the international well-known magazines, especially their high quality research achievements. So it's difficult to get all the needy informationjust bysearching or retrieving the domestic literature webpages or databases. A professional information worker should master at least one foreign language,especially English. Over 60percent of research papers are written in English, and over 95 percent of the SCI-includedpapers are written in English.
