How to svn copy only specific folders from trunk to new branch

Question

I'm new to SVN and trying to learn the process. I have a trunk with many directories that looks something like this:

trunk
  folder1
    language1          
    language2
  folder2
    language1
    language2
  global
    language1.jpg
    language2.jpg
  webroot
    language1
    language2

I want to copy certain files and folders over to a new branch using svn copy. Right now, I'm copying over everything, which is not necessary:

svn copy http://url-to-repo/trunk http://url-to-repo/branches/new-branch

How can copy specific items so that my branch looks something like this?:

branches
  new-branch
    folder1
      language1                    
    folder2
      language1        
    global
      language1.jpg
    webroot
      language1
