In Chinese, that limits their speed to about 400 characters per minute, in English, to about 200 words a minute, not even close to the speed of the eye and brain working together--from 3,000 characters a minute to as much as 80,000 characters a minute.
口頭閱讀速度，中文每分鐘約四百字，英文約二百字（這是美國人的速度，中國人更慢，大約每分鐘一百廿字）。
