解析：选A。"你在哪儿捡的钱包？""就在我们散步的海边。"答语是强调句的省略结构，省略了that I picked up the wallet，该强调句中包含一个定语从句，先行词为the beach，从句缺少地点状语，故选A。

　　When I received a recent invitation to visit Thailand, I immediately thought of the lovely, helpful elephant in Bangkok. I recalled learning its story from an article entitled "Bangkok's Little Elephant" that I read in one of my primary school textbooks. The article told about a smart elephant that not only dragged a car out of the mud, but also cleaned the vehicle with water it had fetched with its long trunk. From then on, the very mention of Thailand has reminded me of images of elephants.

　　We arrived at Bangkok at 9 p．m. We could find lots of elephant sculptures and other souvenirs featuring the animal - Thailand's national symbol - in shops and roadside stalls.

　　The only place I saw real elephants in the Thai capital was at Siam Niramit. In this show of Thailand's history and cultural diversity, actors rode two elephants onto the stage. But I didn't have enough time for a picture with them before leaving the theater.

　　It wasn't until two days later that we were able to take a closer look at Thai elephants. During our stay in Chiang Mai in the north, we visited the Measa Elephant Camp, some 20 minutes' drive from the city center. The camp is home to 78 elephants. When we arrived there in early morning, many black elephants, some with creamy white tusks, were enjoying their daily bath in the river.

　　In the Thai Buddhist culture, rare white elephants are believed to be sacred animals. Whenever a white elephant is captured, it must be presented to the king.

　　In the past, elephants served as weapons in north Thailand. Later, elephants were employed to transport logs from the mountains. At last, the local people started to train the elephants to perform for tourists.

　　At Measa, we were amazed by the elephants' skills. They could not only play football, but also paint wonderful pictures with their trunks.

　　At the end of the Thailand tour, everybody in the group rushed to purchase elephant sculptures, toys, ornaments and T­shirts. I was no exception. The elephant­pendant key chains I bought turned out to be popular gifts for my colleagues.
