Dear Li Lei,How are things going?Last week I went to Kunming with my family. 【1】 The weather was nice and warm. We stayed in a nice hotel（宾馆）with a large yard. 【2】 We went swimming a lot. That was interesting. We had meals in the hotel, too. 【3】 We also ate a lot of fruits like bananas, pears and pineapples (菠萝).On Friday, we went to Shilin by bus. The mountains were very beautiful and I took lots of photos. 【4】 The clothes in the shops were very nice! I liked them very much. 【5】 Mother told me not to buy any. And I was not happy. But I enjoyed the trip to Kunmi 把(－12)－(－13)+(－14)－(+15)+(+16)统一成加法的形式是________________,写成省略加号的形式是_________________,读作　　　　　　　　　　　　．
