Answer 1

叫句子成分。
先给的叫悬赏，后给的叫奖赏。
For a long time, both students and instructors have seemed contented with discussing grammar and understanding passages through reading, ignoring the oral communication which is much more important.
for a long time ---介词短语，作时间状语
both students and instructors 句子的主语
have seemed contented with 谓语
discussing grammar and understanding passages through reading 宾语
ignoring the oral communication(+定语从句）--现在分词短语作状语，表示“伴随情况”
which is much more important--定语从句，修鉓先行词the oral communication.

Answer 2

for a long time 时间状语
both ..instructors 主语
have seem 各种助动
contented with 谓语
discussing and understanding passages介宾结构充当宾语
through reading方法状语
ignoring后面是现在分词做状语从句
which后面一个小定语从句
不懂有错追问,谢谢

Answer 3

For a long time（状语）

主语 both students and instructors 

谓语动词 have seemed contented with

•  discussing grammar and understanding passages through reading, 

• ignoring the oral communication （discussing和ignoring是并列的宾语成分）

定语从句 which is much more important.修饰the oral  communication
