  A表示现在( 指说话人说话时)正在发生的事情。
  例:We are waiting for you.
  B. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。
  例:Mr. Green is writing another novel.
  (说话时并未在写,只处于写作的状态。)
  例:She is learning piano under Mr. Smith.
  C.已经确定或安排好的将来活动。
  I'm leaving for a trek 1 in Nepal next week.(已经安排了)
  we're flying to Paris tomorrow.(票已经拿到了)
  在实际运用时,现在进行时常用以下几种情况:
  (1)当句子中有now时,常表示动作正在进行,这时要用现在进行时。如:
  They are playing basketball now.现在他们正在打篮球。
  (2)以look, listen开头的句子,提示我们动作正进行,这时要用现在进行时。如:
  Listen!She is singing an English song.听,她正在唱英语歌。
  (3)表示当前一段时间或现阶段正在进行的动作,且此时有this week, these days等时间状语,这时常用现在进行时。如:
  We are making model planes these days.这些天我们在做飞机模型。
  (4)描述图片中的人物的动作,也为了表达更生动。此时也常用现在进行时。如:
  Look at the picture. The children are flying kites in the park.看这幅图,那些孩子正在公园放风筝。

vi.作长途艰辛的旅行;n.长途艰苦的旅行
  • We often go pony-trek in the summer.夏季我们经常骑马旅行。
  • It took us the whole day to trek across the rocky terrain.我们花了一整天的时间艰难地穿过那片遍布岩石的地带。
