【简答题】
Gordon Williams’s hobby may seem strange to people when they meet it for the first time. But it is a traditional craft(手艺).He builds model ships inside old bottles. Gordon has always loved ships, especially sailing ships from the old days. His interest in this hobby began many years ago when he visited a museum in Ottawa, Canada, where there was a display of model ships in bottles. Gordon thought the display was wonderful. But he wondered how the craftsman got the ship through the thin neck of the bottle. Gordon decided to find it out. He found an old master craftsman who was willing to teach him the necessary skills. First, Gordon takes an old bottle. Then he puts in a layer of putty(一层油灰),carefully shaped and painted it look like the sea. Next he builds the ship. To get the ship through the neck of the bottle, Gordon holds down the masts(桅杆).Once the ship is inside the bottle, he takes a long, thin tool to raise the masts. Gordon has completed well over one hundred m odels. His wish is to build bigger model ships, such as aircraft carriers. This will be more challenging, as he will have to build the ship actually inside the bottle. His hobby certainly needs time, patience and a steady hand. 根据短文内容,选择最佳答案,并在答题卡上按要求作答。 小题1:What’s their opinion when people first meet Gordon’s hobby? A.Useful. B.Traditional. C.Interesting.
