I agree with the above answers - spending time reading and discussing is good. You can see that he knows the vocabulary, picks up key information... and give him tips if this is not the case. I have seen where my kids read but won't pick up the dictionnary for a few words they didn't know that would certainly help them understand better - so get the child in the habit of doing this.
However, if it really seems to be a problem, you might check for dyslexia. My daughter had therapy in primary school and greatly improved - now in Jr. high, I see some of the same symptoms - its isn't the classic case of mixing b and d, etc. but she skips over words when she reads so she misses key information, particuarly if she reads in her head, and not outloud. Outloud she has few problems, but she can't handle all her work reading outloud.
