根据句意,用所给单词的适当形式填空:
1.Don't get on the bus until it _____ (stop).
2.Many new changes _____ (take) place in our city and now we are getting ready to welcome the 2008 Olympic Games.

1.stops 因为it要用第三人称单数。时态与前面保持一致
2.are taking 因为and是连词,而后面是进行时表将来,所以这里也用进行时

stops
are taken/taking

stops,3人单
are taking and是并列连词,后面are getting是正在进行时(表将来),所以take也要用正在进行时

1. stops
2. have taken place

认为第二句填 have taken
