You're welcomed to take the spaceship to Mars. I'm the captain. You will find some useful things in the bag under your seat. You can use them during the trip and after we arrive. Please take out your bag now and check it.
Your air bag will help you walk outside on Mars. You can carry it on your back. The tube (管子) coming out of the bag will carry air to your helmet(头盔). Inside the helmet, you can find a phone. If you go out of the hotel on Mars, you can use it to contact with your family. And the space shoes will help you walk on Mars. You also have a pair of special sunglasses for the trip. The sunglasses are quite strong on Mars. Your watch will be no use when we arrive, because time runs differently there, please put on the space timer.
In the bag, there is also some medicine for you if you don't feel well. Finally, remember not to take off your suit. It will help your body get used to(适应)the temperature on Mars.
Thanks.
