答案

I.【主旨大意】本文是一篇說明文。文章講述了交通燈的發(fā)展史。

1.C細(xì)節(jié)理解題。根據(jù)第二段第三句"Thecolourredwasusedtomean'stop'because

itwarnedpeopleofdanger.”可知選C。

2.B詞義猜測(cè)題。從上下文可知:軌道上經(jīng)常發(fā)生事故,是因?yàn)橐恍┗疖囁緳C(jī)認(rèn)為黑夜中星

星閃耀著白光意味著“通行”，所以綠色與白色信號(hào)燈代表的指令發(fā)生了互換。綠燈意味

著“通行”，白燈意味著“小心二

3.D推理判斷題。第二段最后一句說綠燈表示“小心”，第三段最后一句說白燈表示“小心”，

第四段和第五段最后一句是黃燈表示“小心”，所以順序應(yīng)該是“綠-白-黃”。

4.B主旨大意題。本文講述的是交通燈的歷史。
