英文文化問題,點解入面既implement要加ing?

The government would face challenges implementing this policy,but i believe it would be as successful as the indoor smoke-free policy

點解上面果句既implement 要加 ing???
更新: 咁我想問下哩句呢?

The government can help with more education and having promotions (pointing) out the risks involved in drinkand drug driving.



哩句入面問ing 都係gerund???可唔可以講下係咪咩情況都可以用???

如果第一句個pointing 變做to point又得唔得?thx
