5. penpal

6. I cannot list the steps because each one seems to be different, at least from what I've read in newspapers and seen on TV. Try this, though:http://www.google.com/search?rlz=1C1GGGE_enUS379US379&aq=0&oq=robbery+scene+%22&sourceid=chrome&ie=UTF-8&q=robbery+scene+heat
The two videos at the top of these search results, especially the one on the right, and the second link will probably give you information that you can write into a list of steps. You may have to watch the video more than once or twice.

Sorry -- "... especially the one on the left ... "

Sure! Here are the checked sentences and any corrections that are needed:

1) He proposes he should pay for the racer himself.
- This sentence is grammatically correct.

2) She spent pleasing days in Sicily.
- This sentence is grammatically correct.

3) She has very pleasing manners.
- This sentence is grammatically correct.

4) What age do you have to be to drive a car in Spain?
- This sentence is grammatically correct.

5) Tell your English penfriend (?) what you must and mustn't do at your school. Refer then to the household chores you have or don't have to do at home, describing one in detail.
- The word "(?)" doesn't make sense in this sentence. It seems like it might be a placeholder for something. Otherwise, the sentence is grammatically correct.

6) Can you help me describe what usually happens during a robbery or shoplifting? Thank you.
- This sentence is grammatically correct. However, I removed the article "a" before "shoplifting" because it is typically used without an article.

7) A man pushed past me when I was getting off the bus and snatched my purse. (I realized it only later).
- This sentence is grammatically correct. However, the part in parentheses seems like an afterthought or additional information. You could make it a separate sentence or use appropriate punctuation to indicate the additional information, such as: "A man pushed past me when I was getting off the bus and snatched my purse. I only realized it later."
