1. She is in London. ("to be" is the verb format used for the third person singular, so we use "is" instead of "to be".)
2. Carry is writing a book now. (We add "ing" to the verb "to write" to show that the action is happening in the present.)
3. My parents are going to Spain at the weekend. (We use "are going" because the subject "my parents" is plural. We also add "to" before the destination to indicate their direction.)
4. You are running too fast. (Again, we use the verb format "are" because the subject "you" is plural.)
5. My brother draws very well. (No changes are needed for this sentence as the verb "to draw" is appropriate for the subject "my brother".)
6. My wife usually works at the office. (We use the verb "works" because the subject "my wife" is singular and in the third person.)
7. Most days, Tom cycles to work. (We use the verb "cycles" because the subject "Tom" is singular and in the third person.)
8. When does the lesson start today? (We change "is" to "does" to form a question in present simple tense. We use "start" instead of "to start" because "when" already indicates the present tense.)
9. What’s your brother doing? He is doing the crossword in the newspaper. He does it every day. (In the first sentence, we use "is doing" to indicate an ongoing action. In the second sentence, we use "does" because it is a habitual action.)
10. I’m afraid I’ll lose this game of chess. I play very badly. I usually play much better. (In the first sentence, we use "I’ll" to represent "I will." In the second and third sentences, we use "play" because the subject "I" is in the first person.)
