阅读理解。 I was waiting for the bus to take me down from the Janiculum Hill into the city of Roma when I turned and saw black smoke rising into the sky. It seemed to be coming from my studio, a small, cabin-like study built up against the ancient Roman wall. I'd arrived there three weeks before with my most important thing: the first draft (手稿) of my new novel. The smoke? I thought of the electric coil (电热棒) I'd been using to heat water for the endless cups of tea I need to fuel my writing. What if I had started heating water and forgotten about it? I supposed the coil had turned over from the cup and started a fire that would not only destroy the studio but also the pages of work I had spent years on and I could never rewrite. I hurried back, but soon saw that the smoke came from the old leaves and branches in the neighbor's garden. I felt relieved (轻松的). But since I was now so close, I went into my study to have a look anyway. The electric coil was red, and the water I'd meant to use for tea before I left had all boiled out of the cup that had already turned over and the red-hot coil had toppled (倾斜) onto the desk and was burning the wood. My pages that might have burnt in a second were only inches away. Drawn by the smoke, I'd come back just in time. 'Thank God' I said. Of course, thank my luck. 1. The author was leaving for ______.
