B.The wind speed put next to the mark can be obtained from local media.

C.The end of the strip is taped into a loop to add support to the paper strip.

Answer 1

【答案】

【1】C

【2】B

【解析】

这是一篇说明文，是一个趣味实验。这个实验讲述的是自制一个风速计，更好地了解风速计的工作原理。

【1】推理判断题。根据what happened中An anemometer like this is best for measuring gentle winds because even a little wind lifts the paper strip a bit.(像这样的风速计最适合测量微风，因为即使是微风也会把纸带吹起一点。)由此可知，用这种方法制作风速计的目的是为了更好地了解风速计的工作原理。故选C。

【2】细节理解题。根据what happened中the local weather report is usually for the slow speed，not the gusts.“当地的天气预报通常是低速的，而不是阵风。”由此可知，标记旁边的风速可以从当地媒体获得。故选B。
