【典型例题】 Passage 9 （2020杭州B卷）
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 meant “go”.
What is the passage mainly about
The advantages of traffic lights. B. The history of traffic lights.
C. The importance of traffic lights. D. The meanings of traffic lights.
文章大意
However, there were many dangerous accidents on the train tracks. Some train drivers thought a star shining in the night sky was a white light that meant “go”。 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 solve down and prepare to stop.
What is the passage mainly about
The advantages of traffic lights. B. The history of traffic lights.
C. The importance of traffic lights. D. The meanings of traffic lights.

【典型例题】 Passage 5 (2020重庆B卷）
Facial recognition technology(人脸识别技术) is widely used today. For example, police use it to search for bad guys. It's also used to unlock phones or doors.
Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising(广告）。
Such systems are going through tests in a small number of stores. One facial detection system can judge a person's “happiness” or “fear” level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.
( ) The best title of the passage may be________.
A. Facial Recognition Technology Entering a New Field
B. Facial Recognition Technology Looking for Bad Guys
C. Facial Detection Technology Going into Advertising Field
D. Facial Detection Technology Improving Buyers' Experience
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people's ages and five levels of feelings-from “very happy” to “very unhappy”。
Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices.
Some are against the idea of using such systems. Pam Dixon, the head of a privacy(隐私）group, is one of them. She thinks the strange actions may cause something unfair. For example, a business could raise the price of a product according to a person's age and feelings.
However, one store testing the technology explained they wouldn't store people's information like names or ages. And the advertising board system maker said it didn't keep any personal information or record any videos.
