Stop opening my emails automatically!!!

Since one of the latest updates, the first email in my list of emails in every category, like primary, promotions, updates, etc., automatically opens. I hate this! Sometimes I just want to take a quick look at my emails to see what is in there and label them. I dont want them automatically opened, causing me to have to repeatedly select them and mark them unread. The fact that Im suffering from repetitive stress pain makes this much worse, as every touch to my iPad screen hurts, worsening with every touch. Now I have a lot of extra touching because of having to mark things as unread repeatedly. Get rid of this annoying and painful feature!
