A good way of combine this sentence is:
By jumping into the air, the player had just scored the winning goal.
They encouraged anti semitism
The sentence "My dog is so peculiar- sometimes he'll bark at absolutely nothing!" uses all of its words correctly. I can't tell which is the vocabulary word, since it's not italicized, but this is the only fully correct sentence. If the vocabulary word is peculiar, the reason it works in this sentence is because it means "weird" or "odd", which would both also work in this sentence.
