(1) far通常不用于肯定句,特别是在口语中,如:We walked far.和I live far from the center of town. 这两句话并非不对,但多数人喜用a long way。
- You must be tired; you have walked a long/good way .
你一定累了;你已走了很远的路。 - It's a very long way from here to Africa.
从这里到非洲路程很远。
(2) 在疑问句和否定句中用far是很自然的。
- How far did we walk?
我们走了多远了? - She doesn't live far from the railway station.
她住得离火车站不远。
(3) 在肯定句中常用在too和so后。另外,还常用在as/so far as, so far, far from(远非是)等习语中。
- You've gone too far .
你走得太远了。 - It's OK as far as I know.
就我所知,没有问题。 - We haven't had any problem so far .
截至目前,我们还没有任何问题。 - The teacher is far from satisfied with my results.
老师对我的成绩远非满意。
