Whether you are new to doll collecting or have been doll collecting for years, you need to have a good grasp of doll collecting basics. The basics you'll need range from how to value and identify your dolls, to how to protect and preserve your dolls, to how to photograph you dolls and get the best prices for them on eBay.
To be verbs are things that do not show action. For example, The grandmother is nice.. Is is the to be verb in that sentence. A trick to remember that is Grandmother=nice. If the equals sign makes sense in between the words, then it's a form of a being verb. Sometimes, verbs like is can be used as part of a verb phrase and be an action verb.
Look for a passive verb. Passive verbs include a form of to be as well as a past tense verb. For example, was bitten or been blessed. This is one of the easiest ways to tell a passive sentence apart, but the next step is also useful for figuring out difficult sentences, and becoming familiar with how passive and active sentences work.
