1. Can I use the expression "Only this"???
2. Can I use very much with all the verbs? Ex: "She speaks very much". / " I study very much". / "I dance very much".
 Why not? For example,
Max: What did you buy today?
Pat: It's all in the bag on the table.
Max: (looking in the bag) Only this? (in other words, you bought only this?)
 No. But,
EX: I love you very much.
