1. The problem is to choose the correct verb form in present simple tense for given sentences. 2. The rule for present simple tense: - For he, she, it (3rd person singular), add **-s** or **-es** to the base verb. - Use **-es** if the verb ends in -ch, -sh, -x, -s, or -z. - For verbs ending in consonant + y, change y to i and add **-es**. 3. Applying the rules: - My parents speak / speaks English very well. Since "parents" is plural, use base verb: **speak**. - He tidy up / tidies up his bedroom every day. For he, change tidy to **tidies**. - My dad and I enjoy / enjoys cooking. "My dad and I" is plural, so use base verb: **enjoy**. 4. Complete with do or does: - Where **do** you go to school? - **Do** the children brush their teeth after dinner? - What **does** Thomas do at the weekend? - **Does** Mum sleep all night? 5.
