一、书信：
Dear editor,
I am writing to express my concern about the littering problem that has become increasingly serious in our community. People are used to throwing litter everywhere, which leads to a negative impact on the environment and health.
To solve this problem, I have several suggestions. Firstly, we should raise people's awareness of environmental protection through various activities, such as organizing campaigns and workshops. Secondly, we need to set up more trash bins and recycling facilities in public places, like parks and streets. Thirdly, it is essential to enforce stricter laws and regulations to punish those who violate the rules.
I hope that my suggestions could contribute to reducing littering in our community. Thank you for your attention.
Yours faithfully,
Li Ming

My unforgettable travel
Last summer holiday, I had a wonderful trip to Sanya with my family, which left me with unforgettable memories.
On the first day, we went to the famous scenic spot Nanshan Temple, where we admired the magnificent Buddhist architecture and enjoyed the peaceful atmosphere. On the second day, we visited the stunning Yalong Bay, where we swam in the crystal-clear sea and played some beach games. On the third day, we went to the Duty-free Shop, where we bought many souvenirs and gifts for our friends and relatives. On the last day, we went to the local food market, where we tasted the delicious seafood and snacks, which were really amazing.
In summary, this trip not only enriched my knowledge of culture and history but also provided me with a good opportunity to relax and recharge myself. I look forward to visiting Sanya again in the future.
