@SubscribeEvent
    public static void offers(VillagerTradesEvent event){
        if(event.getType() == VillagerProfession.FLETCHER){
            event.getTrades().put(1, Collections.singletonList(new BasicItemListing(32, new ItemStack(ModItems.EXPLOSIVE_ARROW.get()), 3, 5, 0.03f)));
        }
    }

It works. But for tier one, only my offer is loaded, and vanilla is not. How to fix it?

you replace the vanilla Trades with Int2ObjectMap#put in this case,
you need to call Int2ObjectMap#get which returns a List of all Trades for level 1 then you can call List#add:

event.getTrades().get(1).add(<your_trade>);

Oh. Okey
