however用在句首?
“Another point I noted from my observation of the student corpus is that with 1 or 2 exceptions,Hong Kong students only ever use However,at the beginning of a sentence.
In contrast,the native speaker corpus reflected a much more flexible approach - one point of particular interest to me is that in most cases when However is used to begin a sentence,that sentence just happens to be the first sentence of a new paragraph.”
