find the mistakes in the following sentences and correct them 1 the first phone with a camera appeared on may 1999 2 last tuesday ,mai said to me that she was having an english test tomorrow

1. The first phone with a camera appeared in May 1999.

• Mistake: The preposition "on" should be "in" when referring to a month.

2. Last Tuesday, Mai told me that she would be having an English test the next day.

• Mistake 1: The comma after "Tuesday" is unnecessary.
• Mistake 2: When reporting speech about a future event from a past time ("last Tuesday"), the tense and time adverb need to be adjusted. "was having" should become "would be having" and "tomorrow" should become "the next day".
