2. I to Doris. (to talk)

2. I am talking to Doris.

Explanation:
To complete this sentence using the present continuous tense, we need to conjugate the verb "to talk" to match the subject "I." In the present continuous tense, we use the "am" form of the verb "to be" followed by the present participle form of the main verb.

Step-by-step solution:
1. Start with the subject "I."
2. Conjugate the verb "to be" to match the subject. In this case, we use the form "am" since the subject is "I." Therefore, we have "am."
3. Add the present participle form of the main verb "to talk," which is "talking." Therefore, we have "I am talking."
4. Finally, add the preposition "to" and the object "Doris" to complete the sentence. Therefore, the final sentence is "I am talking to Doris."
