repaired 电视被修，所以用被动
to cheer try one's best to do sth
to help volunteer one's time to do
organization 史蒂芬是团体的一员，需要用名词形式，故用organization
to help enjoy find ways to do sth ， help sb do sth

1.repaired；haven't Sth done 完成某事，固定搭配
2.cheering,try Sb's best doing Sth,尽量做某事，固定短语
3.helping,spend time doing Sth,花时间做某事，还是固定短语
4.organization,机构，这里是取organize的名词形式
5.to help...to enjoy,这个凭感觉写的
第一题repair加ed因为是被动语态，意思是我的tv需要被修理，第二题那个c的单词前面加to，第三题一样的后面两题都看不全啊小朋友你下次图片一定要拍清楚，有什么其他问题可以私信我
1. I'm going to have my TV set repaired this Sunday.
to have sth done. 让别人干某事。
2. Mother is trying her best to cheer up the sick boy.
to try one's best to do sth. 竭力做某事
3. They all volunteer their time to help other people.
volunteer to do sth. 自愿做某事
4. Stephen is a member of an organization which protests rivers and lakes in China.
organization 是organise的名词形式。在英式英语中，为organisation.

help sb （to）do sth 帮助某人做某事。美式英语有to

2 cheer
( try one's best to do sth 尽力做某事）
3 to help ( 不定式作目的状语）
4 organization 名词‘ 组织’ （ 根据an 和句意可知）
