Buying a dictionary like this is not a suggestion; it is a must. Get a good notebook, a nice pen, read a page or two each day when you are so alert. Focus on the examples and try to soak in how these verbs work. To know them is a must because English is a Germanic language and some verbs are expressed in more than two or three words together, unlike French, Spanish or Italian. Just remember that the example is more important the definition. Try to make your own examples and play with phrasal verbs, have fun with them as you go.
