Step 2.Definition: A linking verb is a word used to connect the subject of a sentence to further information about its state. The most common linking verb is“be (am/is/are/was/were/been)”. eg. The new medicine is effective. Step 3. Different types of linking verbs: 1)“存在持续”类：表示存在或具有某种特征或状态的持续。这类系动词强调“存 在”“持续”。常见的有： be (是)，seem (似乎是)，appear (似乎、显得)，prove (证明 是)，remain (依然)，keep (保持)，stay (保持)，continue (继续、仍旧)，stand (处于 某状况或情形)等。例如: 1.The story proves true. 2. They appear in favor of the new drug. 3. Please keep quite in the library. 4. It's already ten in the morning. The store remains closed.
