阅读理解Apollo 15 was the first flight to the moon that included a spacewalk. On our return trip to Earth, we needed to recover film canisters(胶卷盒) from the service module. Because it was a new activity, an incredible amount of preparation went into it. I evaluated the entire plan in terms of safety and results. During our pre-flight analysis, we installed a warning tone in the suit in case of low oxygen pressure. Once all this pre-flight work was accomplished, the actual spacewalk was easy and accomplished in a short time. I had the pleasure of being outside the spacecraft for 38 minutes, and here's how we did it. We started suiting up an hour or so before the actual spacewalk. I got a little rush as the Command Module was depressurizing because I was then completely dependent on the pressure in the suit to keep me alive. I had practised this procedure many times on Earth, but this was for REAL and I had to do it just right. Once the cabin pressure went to zero, we opened the hatch(舱口) and went out. What a feeling to be free in deep space! I concentrated on reaching for the handholds as I made my way to the back of the service module so I would not float away. I had a small problem right away. The high-resolution camera was stuck out in its extended position. I reached the canister, put a safety clip(安全扣) on it, attached by a rope to my wrist, and pulled it out of the bay. Turning around again I made my way back to the hatch. So far, a piece of cake. After another two trips, I finished my task. By turning my head just so I could position myself so that both the Earth and the Moon were in field of vision. I realized that no one in all of history had ever seen this sight before. What an honour it was.
