A
The idea that red means stop and green means go has influenced our lives in more ways than just traffic signals(信号灯). 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 meant danger, long before cars were even around. This most likely started because it's the color with the longest wavelength(波长) 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 painted yellow.
So next time you're impatiently waiting at a traffic light, don't get so mad at them; they've certainly come along way.

三、任务型阅读-多任务混合（本大题共1小题，共10.0分）
The International Space Station(ISS), which goes around Earth, is the second brightest object in our night sky after the moon. In 1998, the first piece of the ISS was sent into space. Since then, 230 people from 18 countries have visited it.
①________ Five space agencies—those of the United States, Russia, Canada, Japan and some countries in Europe—worked together to build it. China is not part of the ISS program, but it has helped with some of the station's experiments.
The ISS holds three to six people at one time. Astronauts living there work on different science projects. The ISS has hosted over 1,500 such projects so far. 900 of those have been put into use in the science field.
②________ And it is coming to the end of its mission(使命). In 2011, Russia said that the ISS would stop working in 2020 and it was becoming "space junk". But the US later said it would use repairs to extend(延长) its service life to 2025.
The ISS costs $3-4 billion each year. Many have argued that the money could be better spent improving conditions on Earth.
"What will happen to the ISS after 2025 is unknown. There are lots of possible uses," said Jeffrey Hoffman who ever worked in ISS. He is now a professor at a university.
China will soon have its own space station, becoming the third country after Russia and the US to do so. The station is set to be finished around 2020.
