我知道这句话的出处，后头晚上找资料帮你改，等着哦

therefore, the task of dictionary writing is not to set up authoritative statements about the ''true meanings'' of a certain vocabulary, but to record as much as possible how various words function.

硬伤Therefor->Therefore(应该是你手滑打错了吧）
statement->statements(这里是一个泛指的意思,“各种声明”）
do one's possible->possible ways of(原来的写法不知所云）
还有软伤,字数限制无法发,再交流

Therefor...statements... recording to do ... possible about how ....
字数有限，只能这样，错的给你改过来了。
