ESL For Chinese Speakers: Tense Marking - No Time Adverb, Add -ed or Irregular Form

What It Is

Tense marking in English can be tricky when there's no time adverb. We need to add -ed or use an irregular form to show the correct tense. For example, "I walked to the park" (past tense) vs. "I walk to the park" (present tense). ESL learners often struggle with this because their first language might not have the same rules.

Key Rules

• Use -ed for regular verbs in the past simple tense (e.g., "I walked to the park").
• Use -ed for regular verbs in the past participle (e.g., "I have walked to the park").
• Irregular verbs have unique past forms (e.g., "I went to the park").
• Use -ed for regular verbs in the past perfect tense (e.g., "I had walked to the park by the time I arrived").
• Use -ed for regular verbs in the present perfect continuous tense (e.g., "I have been walking to the park for an hour").
• Some verbs change their spelling in the past tense (e.g., "I learned a new language").
• Some verbs change their spelling in the past participle (e.g., "I have learned a new language").
• Use was/were for the past simple tense with I/you/he/she/it (e.g., "I was at the park").
• Use was/were for the past perfect tense with I/you/he/she/it (e.g., "I had been at the park by the time I arrived").
• Use did for the past simple tense with I/you/he/she/it (e.g., "I did my homework").
• Use had done for the past perfect tense with I/you/he/she/it (e.g., "I had done my homework by the time I went to bed").
• Some verbs have different forms in the present and past tenses (e.g., "I go to the park" vs. "I went to the park").
• Use have/has for the present perfect tense with I/you/we/they (e.g., "I have been to the park").
• Use has for the present perfect tense with he/she/it (e.g., "He has been to the park").
• Use had for the past perfect tense with I/you/we/they (e.g., "I had been to the park by the time I arrived").
• Use had for the past perfect tense with he/she/it (e.g., "He had been to the park by the time I arrived").

Common ESL Errors

• Error: I go to the park yesterday. Why it happens: Interference from the learner's first language, which might not have a similar tense system. Correction: I went to the park yesterday.
• Error: I eat breakfast every morning. Why it happens: Overgeneralization of the present simple tense. Correction: I eat breakfast every morning (correct, but consider using the present continuous tense for a more dynamic description).
• Error: I have go to the park. Why it happens: Lack of understanding of the present perfect tense. Correction: I have been to the park.

Practice Exercises

1. Fill in the blank: She (go) to the store yesterday. Answer: She went to the store yesterday. Reason: Use the past simple tense to describe a completed action.
2. Fill in the blank: I (eat) breakfast every morning. Answer: I eat breakfast every morning. Reason: Use the present simple tense to describe a regular action.
3. Fill in the blank: I (have been) to the park all day. Answer: I have been to the park all day. Reason: Use the present perfect continuous tense to describe an action that started in the past and continues up to the present.
