有三个英语句子改错的题目 关于连词的 帮忙看看

1.news后加that 是一个同位语从句
2.if改成whether whether to do 是固定说法 if不能这么用
3.both前加and 两个分句中间必须有连词连接

1、The news that our team has won the match is true.
同位语

2、I haven't decided if to go there.

if 改成whether

3、I have two sisters, both of them are students

both of them → both of whom 非限制性定从

1，news后面加which
2，to go改going，介词后面跟动名词
3，both前面加and

1、The news that our team has won the match is true.

2、I haven't decided whether to go there. if和whether 的区别

3、I have two sisters, both of whom are students.(定语从句).
或I have two sisters, and both of them are students.

news后加that
if 变 whether
them 改 whom 这考定语从句

1.news后加that 是同位语从句不能用which
2.把if改成whether表示是否不能用if
3.把them该成whom 表示非限制定语从句
