答案

参考答案:B

解析:

选项A不正确,题干只是说婴儿睡眠时不关灯会增加孩子患近视的可能性,并没有强调长大后一定不得近视,所以可排除;选项C也不正确,原因与A同,选项D与题干无关,也要排除。只有选项B是题干论述可能推出的结论。故选B。

     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 models. 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.
