How zebra stripes and other patterns have made crossing streets safer
Crosswalks are marked parts of the road where pedestrians have the right of way to cross. Although they seem like products of the modern world, crosswalks have actually been around for more than 2,000 years. The first crosswalks were invented in the ancient city of Pompeii, Italy. They consisted of large rocks placed on the road. When it rained heavily, they allowed people to cross the road without stepping in water or mud on the ground. They also forced horse-drawn carts to slow down and watch out for the pedestrians. These crosswalks are still found in parts of Italy today.
In 1899, the United States had its first automobile collision that resulted in the death of a pedestrian. After that, the number of cars on the road increased significantly, and so did traffic accidents involving pedestrians. In the 1930s, the US and the UK were trying to figure out a way to control pedestrian traffic. After experimenting with various designs, the UK decided to use black and white stripes, which could be easily spotted by both drivers and pedestrians from a distance. This black-and- white crosswalk became known as the “zebra crossing,” which is now used by many countries around the world.

♦ 簡應句的用法
本文的 “and so did traffic accidents...” 為肯定簡應句。
簡應句是用來附和前面的敘述,表「也/也不⋯⋯」,有肯定簡應句與否定簡應句之分:
1. 肯定簡應句用 so 或 too。
so 之前要有連接詞 and,後面的句子要倒裝;too 則放在句尾,前面通常置逗點。
| 肯定句, and so + be 動詞/助動詞 + S = 肯定句, and + S + be 動詞/助動詞, too |
例: Sara is a lawyer, and so is her father.
= Sara is a lawyer, and her father is, too.
莎拉是位律師,她父親也是。
2. 否定簡應句用 neither、nor 或 either。
neither 或 nor 之後的句子要倒裝,而且 neither 之前須用 and 連接兩句;either 則置於句尾使用,前面通常置逗點。
| 否定句, and neither + be 動詞/助動詞 + S = 否定句, nor + be 動詞/助動詞 + S = 否定句, and + S + 否定 be 動詞/助動詞, either |
例: Tim doesn’t eat beef, and neither / nor does his younger sister.
= Tim doesn’t eat beef, and his younger sister doesn’t, either.
提姆不吃牛肉,他的妹妹也不吃。

斑馬線和其他圖案如何讓過馬路更安全
行人穿越道是道路上有標記且行人有通行路權的部分。雖然它們看似是現代世界的產物,但行人穿越道其實已經存在超過兩千年了。
第一條行人穿越道是在義大利古老的城市龐貝被發明出來的。它們由放置在路上的大石頭組成。下大雨時,它們讓人們能穿越馬路而不會踩到地上的水或泥巴。它們也迫使馬車慢下來留意行人。這些行人穿越道現今仍存在於義大利的部分區域。
在 1899 年,美國首次發生了導致行人死亡的汽車碰撞事故。在那之後,路上的汽車數量大幅增加,涉及行人的交通意外也增加了。1930 年代,美國和英國試圖想出控制行人交通的方法。在實驗了各種設計後,英國決定使用黑白條紋,駕駛和行人都可以輕易從遠處看到它。這種黑白相間的行人穿越道被稱為「斑馬線」,現在世界各地的 許多國家都使用它。
