There is a special invention in London called “the invisible (隐形的) house”. Its huge 13 walls reflect (反射) everything around it, making it very hard to notice.

A photo of this invisible house 19 became hot online, leaving people with many unknown questions. Some people wondered how much effort the owners put into keeping the mirrors 20 all the time. One man said, “I’ve lived here for 10 years and have driven past it more times than I could count and have never noticed it.

三、阅读理解
Traffic lights are red, yellow and green. They are very important signals（信号）. Traffic lights are usually placed at busy street corners to help control traffic. Sometimes, they are on streets near schools and shops, too. Most young children are taught what each of the colored lights means, so everybody can stay safe.
The first traffic signals were used for trains. The signals were put alongside railway tracks（轨道）. The color red was used to mean “stop” because it warned people of danger. A red light was also the easiest color to see from a distance. Train drivers could see the red “stop” light ahead and had enough time to slow down and stop their trains. A green light was used to mean “take care” and a white light meant “go”.
However, there were many dangerous accidents on the train tracks. Some train drivers sometimes thought a star shining in the night sky was a white light that meant “go” by mistake. So the signals were swapped. The “go” light was changed to green and the “take care” light was changed to white.
During these times, people travelled by train or in carts pulled by horses. Years later, when cars were built, people began to drive them because they could travel much faster than horses. However, the road rules for drivers were not very clear and many people were hurt crossing the roads. Yellow warning signs had to be placed beside the roads to remind drivers to take care and allow people to cross safely.
Today, towns and cities all over the world have traffic lights. Red and green lights match the signals used on the railways. Yellow lights are easy to see, so they are used to warn drivers that they should slow down and prepare to stop.
23．People place traffic lights at busy street corners to ________.
A．control traffic B．stop traffic
C．catch the people against traffic rules D．make the street more beautiful
24．Why was the color red used to mean “stop”
A．It reminded people of traffic rules. B．It helped trains run smoothly.
C．It gave people a warning of danger. D．It was the first color people thought of.
25．What does the underlined word “swapped” in Paragraph 3 mean
A．Designed. B．Exchanged. C．Suggested. D．Compared.
26．In which order did the “take care” light develop
a.A white light b.A green light. c.A yellow light.
A．a-c-b B．b-c-a C．a-b-c D．b-a-c
27．What is the passage mainly about
A．The advantages of traffic lights. B．The history of traffic lights.
C．The importance of traffic lights. D．The meanings of traffic lights.
Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print
Paper was first created about 2, 000 years ago, and has been made from silk, cotton, bamboo, and since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren’t many books, few people learned to read.
Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.
Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD ROMs or machines such as MP3 players.
Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day No, I don’t think the poster of Yao Ming on my bedroom wall will ever be replaced by a computer two meters high!

C．About 1, 000 years ago.
D．In the 11th century.

A．Because people could not read.
B．Because people could not write words on paper.

50．根据上下文语境可知，此处紧接着上一句仍然是关于胡萝卜的，意为：但是现在我们通常称它们为carrot。故答案选G。
51．根据下文Chinese people used to think them poisonous．中国人过去认为它们有毒，推知他们都不敢吃；可知这里是说：但那时中国人不吃西红柿。故答案选F。
52．联系上文可知：中国人在17世纪不吃西红柿，它们被作为一种盆栽种植，因为人们认为它们是有毒的；结合下文And when they began eating them at table, they fell in love with the nice taste.当它们开始在餐桌上吃的时候，他们爱上了它的美味；可知此处是说：欧洲人起初也不敢吃西红柿。故答案选D。
53． Small inventions changed
【详解】根据汉语提示可知，前两空意为“小发明”，small inventions“小发明”，在引号中位于句首，首字母大写；第三空意为“改变”，change“改变”，根据语境，应该用一般过去时，说明已经发生的事。故填Small；inventions；changed。
54． such invention
【详解】根据中英文对照可知，空①缺少“如此”，用such表示；空②缺少“发明”，用名词invention表示，结合空前的a可知，此处用名词单数形式。故填such；invention。
55． Think about it’s used
【详解】think about“想想”，句子为祈使句，用动词原形，“它在我们日常生活中的使用频率”，换句话说是“它在我们日常生活中被多久使用一次”，因此在how often引导的宾语从句中应用一般现在时的被动语态，主语为it，be动词应用is，缩写成it’s，use“使用”的过去分词为used。故填Think；about；it’s；used。
56． do seem to
【详解】根据汉语提示可知，第一空应填do“确实”，放在动词前起强调作用；seem“似乎”，seem to do“似乎做……”，所以后两空填seem to。故填do；seem；to。
57． were listed
【详解】根据中英文对照可知，空处缺少“被列在”，时态为一般过去时，应用一般过去时的被动语态，主语为复数形式，被动语态结构为were+done，动词list“列出”的过去分词为listed。故填were；listed。
58．例文
