閱讀下面的短文，根據(jù)短文內(nèi)容回答問(wèn)題。

The idea that red means stop and green means go has influenced our lives in more ways than just traffic signals (信號(hào)). We have been taught from a young age that the color red means danger and green means it’s okay to move forward. But why were those colors chosen for traffic lights in the first place? For something we have to look at every day, why couldn’t they have been prettier colors?

Well, it’s important to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into a few problems with white meaning go. For example, one train mistook a bright star for a white light and something unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to mean warn. And it’s been that way ever since.

Red has always been a color that mean danger, long before cars were even around. This most likely started because it’s the color with the longest wavelength (波長(zhǎng)) so it can be seen somewhere farther than other colors.

But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials (高反射材料) were developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be printed yellow.

So next time you are impatiently waiting at a traffic light, don’t get so mad at them, they’ve certainly come a long way.

Answer the following question with no more than 8 words.

1.How many colours have been used for traffic signals since the very beginning?

2.What did one train mistake for a white light?

3.Did the colour yellow mean go at first?

4.Why does red mean danger?

5.When were stop signs yellow?

科目：初中英語(yǔ) 來(lái)源：2020年江蘇省鹽城市建湖縣中考一模英語(yǔ)試卷 題型：填空

On June 28, my parents celebrated 70 years of marriage. Mum and Dad live in Calve. They have been through years of hard work and good times always supporting each other.

As a child, I remember my parents working side by side for spring, fall, winter, and summer cleaning or working in the yard, or painting, and wallpapering.

My parents bought a house in Eimont. They never believed they’d be able to own their own home, and to them, it was their castle. They worked hard to decorate it and kept it looking beautiful. They taught us to work hard and to enjoy everything we had.

Mom likes everything-sightseeing, clubs, anything. And everything Dad, even today, can't understand why she always wants to go out! Mom is still active with the Red Hatters women's group and her gardening club. Dad spoils her by taking care of the house, but also watches a lot of baseball and does jigsaw puzzles.

The key to their successful marriage is that they respect each other. With the help of my brother, they also stay current with new technology, Their latest acquisition is an iPad.

My brother, who is 67, and I (now 69),have always known we are lucky to have such great parents. They have shown us what love is, what hard work is, and what respect is all about.

My daughter and I try to see them almost every weekend when we play cards together and catch up on the week's news.

My parents are the glue that holds our whole family together, making holidays and ordinary days special to us all.

I know we are lucky to have them both, I even save all of their voice-mail messages, just so I'll have their voice to hear when they are not here, But Mom keeps telling us all she's certainly going to live to be 100. So we will have a few more holidays, birthdays, and memories to experience.
