  ②在 ...(正)上方 eg:a bridge over the river 河上的一座桥

  3 three thousand years , 前有确切数字,用原形;thousands of数字不确切,词尾加s,与of 连用。 拓展:hundred, million .

  4.被动语态的使用(找出本文含有被动语态的句子,3个)①Tea was invented by accident.②Tea wasn't brought to the western world. ③ beverage was discovered over 3000 years.

  5.回顾:主动语态变被动语态规则一二三。
