Question

帮我一下，顺便告诉我是哪一类名词从句

1the old gentleman never fails to help ——is in need of his help
2——some mammals came to live in the sea is not knomn
a That b What c How d Since
3——you select is all right with me
4 ____is of no concern to us

无选项的只要告诉我 是哪一类名词从句就好，谢谢

Answer 1

补充：1.whoever应该是主语从句，做is in need of his help主语
2How 主语从句
3.用whatever似乎更好 主语从句
4 如果选从句的话，肯定是主语从句了。

Answer 2

1, whoever 宾语从句

2,How 主语从句
3,What 主语从句
4,It 不是从句，是普通句子

追问

抱歉，可能是我没有把选项打出来~表达的不清楚！不过你对了两题半~
