Hi, Tony,

    How are you? It's great to 1 you. I'm on a trip with my 2. Let me tell you what we are doing 3 the moment.

    My father is 4 photos with his new camera (照相机). He's always 5 and it's difficult for 6 to take a holiday. 7 he looks very happy now. My mother 8 getting ready for the picnic (野餐). In a few minutes, we can have our delicious meal. My sister is calling her friend and 9 the warm sun as well.  OK. I have to stop (不得不停下来) 10 It's time to have the meal.

                                                                                                                                                                                    Yours,

                                                                                                                                                                                      Mike
