Ⅱ.短文改错
Dear Peter，
I’m writing to ask whether you are able to do me favor.
I want to have a pen friend，hopefully a girl in early twenties，and with interests to mine.In my opinion，she is someone who interested in traveling，swimming，and playing table tennis.，it would be better for her to have a pet dog as I have kept one at home for some . I have such a pen friend，I think we can share our traveling experiences with each other，taking care of pets，or whatever we have in common. I believe I will improve my English by doing so and learn more about her country.
I look forward to from you soon.
Best regards，
Li Hua

One possible version：
Dear_Sir_or_Madam，
I’m_glad_to_know_you’re_going_to_hold_a_summer_camp_from_July_1st_to_7th_during_the_vacation.I have a great interest in it.There’re so many wonderful activities，such as experiencing cooking culture，visiting worldfamous universities，attending foreign classes，learning family gardening，visiting places of interest and so on，which I think are all very useful to us high school students.
After my careful consideration，I’ve decided to apply to learn family gardening.I want to learn how to grow flowers and plants well.We have a garden，where my parents grow various vegetables，flowers and plants.With the knowledge I learn，I hope I can help them with some work in the garden and manage it better.
Thanks for reading my application.I hope I’ll have a chance to take part in the activity.

Yours_sincerely，
