作文題題目:
AA: 新题6. The following appeared in a letter from a part-owner of a small retail clothing chain to her business partner:
“Commercial real estate prices have been rising steadily in the Sandida Heights neighborhood for several years, while the prices in the adjacent neighborhood of Palm Grove have remained the same. It seems obvious, then, that a retail space in Sandida Heights must now be much more expensive than a similar space in Palm Grove, which was not the case several years ago. So, it appears that retail spaces in Sandida Heights are now overpriced relative to those in Palm Grove. Therefore, it would be in our financial interest to purchase a retail space in Palm Grove rather than in Sandida Heights.”
Discuss how well reasoned . . . etc.

AI: 新题4. Each generation's culture achievements--such as those in music, art ，or literature--represent improvements on the cultural achievements of previous generations.
