Can you please check the grammar in the following sentences? Thank you.

2) Mickey is late for his dance class. Mrs Winter warns him to arrive on time the following time.

7) Our school is a high school with an emphasis on science. It is equipped with state-of-the-art technology and all the teachers are experienced and qualified. Our students are aged between 14 and 18 and are all hard-working (?)and motivated to study (???).

1. Use the "football practice" phrasing.

2. To avoid repetition of "time" try this: Mrs Winter warns him to arrive on time from now on.

3. Space between "asks" and "him"; what does the kit consist of. I'm not clear on the term.

4. Either one works.

5. Any of the three choices works.

6. Either choice works.

7. Comma after "technology" and delete the word "aged"; everything else is fine.

1) The sentence "I have football training twice a week. We play a match against another local team on Saturdays" is grammatically correct. However, you can also say "I go to football practice twice a week" to convey the same meaning.

2) The sentence "Mickey is late for his dance class. Mrs Winter warns him to arrive on time the following time" contains a small error. It should be "Mrs Winter warns him to arrive on time next time."

3) The sentence "She askshim if he's got his kit for jazz dance" contains a typo. It should be "She asks him if he's got his kit for jazz dance."

4) The question "What's the problem?" is grammatically correct. Another alternative is "What's the matter with you?"

5) The sentence "I haven't got my dictionary" is grammatically correct. You can also say "I left my dictionary at home" or "I forgot my dictionary at home." These alternatives convey the same meaning.

6) The sentence "I can't meet you for lunch today. I have a dentist's appointment" is grammatically correct. You can also say "I can't meet you at lunchtime today." Both versions are acceptable. The response "Never mind. I can meet you another time" is also grammatically correct.

7) The sentence "Our school is a high school with an emphasis on science. It is equipped with state-of-the-art technology, and all the teachers are experienced and qualified" is grammatically correct. The phrase "all the teachers are experienced and qualified" means that every teacher in the school possesses experience and qualifications.

The phrase "Our students are aged between 14 and 18 and are all hard-working and motivated to study" is grammatically correct; however, the inclusion of multiple question marks might be a typo.
