Final answer:
The present tense refers to current or general actions, while the present perfect tense is used for actions that started in the past and have a connection to the present.
Step-by-step explanation:
The present tense and the present perfect tense are both types of verb tenses used in English grammar. The present tense is used to describe actions that are happening right now or are generally true. For example, 'I eat breakfast every morning' is a present tense sentence. On the other hand, the present perfect tense is used to describe actions that started in the past and have a connection to the present. For example, 'I have finished my homework' is a present perfect tense sentence.
It is important to note that the present perfect tense is formed using the auxiliary verb 'have' or 'has' followed by the past participle of the main verb. Additionally, the present perfect tense is often used to talk about past actions that have a result or impact on the present. For instance, 'She has lived in London for five years.'
To summarize, the present tense is used for current or general actions, while the present perfect tense is for actions that started in the past and have a connection to the present.
