我不知道他明天是否来。
2. if意为“假如，如果”时，可以引导条件状语从句，而whether没有这个用法。如：
If Simon comes here tomorrow, I’ll call you.
假如西蒙明天来这儿，我将打电话告诉你。

宾语从句的引导词
三、从句原形是特殊疑问句的由连接代词who,whom,
whose,which,what和连接副where,how,why,when
引导。
Do you know whose book it is （ 谁的，作定语）
Could you tell me why the train is late （为什么，作状语）
He wonders who can answer the question.（谁，作主语）
这些连词既有词义，又充当句子成份。

that

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 often give gifts to their parents or take them out for lunch or dinner.
one ... the other ...
一个......另一个......
表示特定范围内两个事物的不同情况。
Common 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 gifts 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.
June
n. 领带 v. 捆；束
当其作动词时, 过去式和过去分词均为tied, 现在分词为tying。
