| | Another infinitive question
My head is spinning trying to get my mind around the infinitives taught in the local English textbooks in JHS in Japan and was wondering if someone could help me out, AND maybe explain the logic into why they break up the infinitives and teach them in different grade textbooks instead of all together?
-- "I use a computer to play games."
-- "I want to find some e-pals."
-- "I have a lot of work to do."
-- "We are glad to have a chance."
I have an idea of how the infinitives are being used in these sentences but I'm not quite confident. Coupled with the fact that I can't understand why they are split and taught in different grades, makes it even more confusing for me.
