in Beijing in 1992.He said that he would go back to the U.S.soon.,过去,3.如果宾语从句所陈述的是客观真理，即使主句用了过去时，从句仍用 _ 时态。例如：The teacher said that the earth moves around the

否“。,如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导。,宾 语 从 句 小 结,巧学宾语从句学习宾从三注意，时态、语序、引导词。时态主从要呼应：主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去；宾从若是表真理，一般现在就可以。语序要用陈述序，切莫照搬疑问句。引导词也不难：That连接陈述句，省与不省要注意。一般问句表“是否”，if/whether来引导。特殊问句作宾从，仍用原来疑问词。三个问题需记牢，切莫丢东忘了西。,Do you know
