Ⅵ. Read the passage and complete the following tasks.
A. Choose the best answers.
Every year, many people drown(溺亡) because there aren't good tools to help them in time. Can we create a strong and helpful tool to save people by the river? This idea comes from Liu Tiancheng, a student from Yangzhou, Jiangsu. The 13-year-old boy invented a telescopic water rescue pole(可伸缩水上救援杆). This invention led him to win the 13th Yangzhou Youth Science and Technology Innovation Mayor Award.
During the summer vacation of 2023, Liu did research in cities such as Yangzhou, Wuxi and Suzhou. He found that along the riverbanks in these cities, water safety tools are mainly throwable lifebuoys(抛掷式救生圈). These lifebuoys can help save people close to the riverbank. But they can't reach people who are far away. Some cities also have rescue poles along the rivers. But these poles are very heavy and can only reach 2 to 5 metres.
To make a water safety tool that's both long and light, Liu invented a rescue pole similar to a fishing rod. “When it's folded(折叠), it's less than 1 metre long, so it's easy to carry. When you open it up, it can reach about 5 metres,” Liu said.
When you pull the string(绳), the dry ice releases gas into the pole. This makes the pole straight and 5 metres longer. You can throw it into the water, and people in danger can hold it. At the same time, an alarm buzzer will go off. There are also glowing rope loops at the end of the pole. People can see them at night.
According to Liu, the rescue pole costs about 120 yuan and only the dry ice needs changing for long-term use. “It can be used in many different situations and helps people a lot,” he said.
()1. What is the main purpose of the passage?
A. To explain how dry ice works in rescue tools.
B. To introduce a teenager's invention for water rescue.
C. To compare different river safety tools in Chinese cities.
D. To describe summer vacation activities of Chinese students.
()2. What is the right order of the following events?
①Liu Tiancheng won the Mayor Award.
②Liu did research in cities like Yangzhou and Suzhou.
③Liu invented a telescopic rescue pole inspired by a fishing rod.
④Liu found some problems with existing(现行的) water safety tools.
A. ②→④→③→① B. ④→③→②→①
C. ③→②→④→① D. ②→③→④→①
()3. What can we learn about old rescue tools from the passage?
A. They are light but don't work for far rescues.
B. Many people think they are easier to use and cost less.
C. They are either too short or too heavy.
D. All cities in China won't use them now.
()4. Why did Liu add glowing rope loops to his rescue pole?
A. To make the tool cheaper to make.
B. To make sure the pole works well at night.
C. To make the pole more beautiful and much cooler.
D. To help users find the dry ice can quickly.
