1. перед деревом - "in front of the tree" - The derivative here is "перед" (in front of) and "деревом" (tree).

2. вдоль реки - "along the river" - The derivative here is "вдоль" (along) and "реки" (river).

3. без радости - "without joy" - The derivative here is "без" (without) and "радости" (joy).
