In some cases , when i run somethings with "sudo" , it tells me "Permission
Denied" , then i should turn to root . i forgot to record the cases .  Did
anyone have any ideas ?

I think it would depend on the use case, but try "sudo -i" (-i meaning
interactive, I believe) and see if that works for you.  I get permission
denied usually with a lot of bash input and output.

The -i option didn't work, it also says Permission Denied

Did you use it interactively?  It should look like this:
alecks@linux:~$ sudo -i
root@linux: ~# echo "sys-boot/grub:2 **" >>
/etc/portage/package.accept_keywords/package.keywords.grub2

Just the way I like to do it.  You could also do something like "sudo
su" and I'm sure someone else here will have all sorts of
alternatives.  Just like I'm sure someone has a way to do it all in
one line, anyway.

sudo -i
sudo su
sudo bash
sudo zsh
sudo screen
sudo tmux

There are plenty of ways to get a root shell with sudo.

echo "some text" | sudo tee /some/file

Are you trying to redirect the output? That can give this message because
the redirection is performed as the user running sudo, not as root.

If Neil is right, you may want to read man tee. It work roughly like
that:
instead of                       do
sudo echo sthg > /etc/file.cfg   echo sthg | sudo tee /etc/file.cfg
sudo echo sthg >> /etc/file.cfg  echo sthg | sudo tee -a /etc/file.cfg

I have use your method , it didn't work .
Like:
sudo echo "sys-boot/grub:2 **" >>
/etc/portage/package.accept_keywords/package.keywords.grub2 echo
"sys-boot/grub:2 **" | sudo tee
/etc/portage/package.accept_keywords/package.keywords.grub2

And the result :
zjhui@gentoo ~ $ ls -l
/etc/portage/package.accept_keywords/package.keywords.grub2
-rw-r--r-- 1 root root 0 Jul  1 10:37
/etc/portage/package.accept_keywords/package.keywords.grub2

It's an empty file.

I think you misread the e-mail. The left hand side below is what you
**shouldn't** do. The right hand side is what you **should** do. So
you **should** run

echo "sys-boot/grub:2 **" | sudo tee /etc/portage/package.accept_keywords/package.keywords.grub2

and no more.
