Very good one! Let's get it UP

True, but not only four. There are at least eight in English. For example:

though (like o in go)
through (like oo in too)
cough (like off in offer)
rough (like uff in suffer)
plough (like ow in flower)
ought (like aw in saw)
borough (like a in above)
hiccough (like up)
