我遇到的困難 The Difficulty I Face

Two days ago, when I was shopping with my friends, we saw a foreigner having some problems with the shop assistant. They couldn’t communicate well, because the assistant did not understand English well. I wished I could help the foreigner to solve the problem, but my English was not good enough. So I must study hard to master the international language well.
兩天前，當我和朋友在購物的時候，我們看到一個外國人與店員有一些爭議。他們無法進行交流，因為店員不懂英語。我希望我能幫助外國人解決問題，但是我的英語不夠好，所以我必須努力學習，掌握好國際語言。
