I come back to italki! Waah! I have not speak English for a long time. During the past year, my job changed and I have to write emails in English everyday, that helps me a lot! But, my listening is not that good. We often have conference calls with foreign partners, contract research organizations, and assay/test services companies (I work for a biotech company as a project manager), I can only obtain 50% information they say via phone.
