当主从句的主语一样时，宾从可以用疑问词+to do 替换
主语+谓语+特殊疑问词 +宾语从句

宾语从句歌
学习宾从三注意，时态语序和连词。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，时态不变无质疑。
语序要用陈述序，切莫照搬疑问句。
That 连接陈述句，省与不省要注意。
从句若表“是否”时，if / whether要慎记。
特殊问句作宾语，仍用原来疑问词。
三个问题需牢记，切莫丢东忘了西。

Dear Xia Yu,
Do you know that there are two special days for parents in America One is Mother’s Day on the second Sunday of May and the other is Father’s Day on the third Sunday of June. On these two days, American children oft en give gifts to their parents or take them out for lunch or mon gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular to celebrate Mother’s Day and Father’s Day in China. I wonder if children over there also give similar gift s to their parents. I believe that there are many ways to show our love. Actually, we don’t have to spend a lot of money. It is also a good idea to help parents to do something instead.
