that 不能省略。

2. 由if/whether引导的宾语从句

if/whether引导，表示“_______”，二者可以换用。
if/ whether在句中不充当句子成分，但不能省略。

Object Clauses with if and whether
是否
二者在以下情况不能互换：

if and whether 的区别
二者在以下情况不能互换：

◆ if 可以引导条件状语从句，意为“假如；如果”，
whether 没有此用法。

Read the passage below and underline the objective clauses. If possible write your own sentences about Mother’s Day and Father’s Day using objective clauses.
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.
一个...另一个
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.
