Answer 1

【答案】

【1】C

【2】B

【解析】

這是一篇說明文，是一個趣味實驗。這個實驗講述的是自制一個風速計，更好地了解風速計的工作原理。

【1】推理判斷題。根據(jù)what happened中An anemometer like this is best for measuring gentle winds because even a little wind lifts the paper strip a bit.(像這樣的風速計最適合測量微風，因為即使是微風也會把紙帶吹起一點。)由此可知，用這種方法制作風速計的目的是為了更好地了解風速計的工作原理。故選C。

【2】細節(jié)理解題。根據(jù)what happened中the local weather report is usually for the slow speed，not the gusts.“當?shù)氐奶鞖忸A(yù)報通常是低速的，而不是陣風。”由此可知，標記旁邊的風速可以從當?shù)孛襟w獲得。故選B。
