九、阅读理解（共12分）
(A) 阅读选择（每小题2分，共6分）
How do we turn ideas into reality This is one of the most important questions in human history. Every great invention started with a question or a problem that someone wanted to solve.
Take the high-speed train as an example. In the past, traveling between cities took a long time. People asked: "Can we make travel faster " This question led to the invention of trains, and later, high-speed trains. Today, China's high-speed railway network is the largest in the world. It connects Xining to Lhasa, a huge distance of 1,956 kilometres.
The radio is another example. Before the radio, news traveled slowly. People in one country didn't know what was happening in another country for days or even weeks. The radio changed all that. Suddenly, news could spread around the world in seconds.
These inventions show us that the power of ideas is limitless. When we face a problem, we should ask questions and look for solutions. That is how we turn ideas into reality.
( ) 1. According to the passage, every great invention started with __________.
A. a question or a problem B. a lot of money C. a big factory
( ) 2. What does the passage say about China's high-speed railway
A. It is the oldest in the world. B. It is the largest in the world. C. It connects all cities in China.
( ) 3. What is the main idea of the passage
How to build high-speed trains.
How great inventions were made and what we can learn from them.
C. Why the radio was more important than the train.
(B) 阅读简答（每小题2分，共6分）
Inventions are everywhere in our daily lives. The camera helps us record beautiful moments. The laptop allows us to work and study anywhere. Sunglasses protect our eyes from the sun. Each of these inventions was once just an idea in someone's mind.
However, not every idea becomes a successful invention. Many ideas fail because they are not practical or too expensive. But failure is not the end. Many great inventors failed many times before they succeeded. The key is to keep trying and learning from mistakes.
Today, we are looking to invent even more amazing things. Mini-devices, smart cameras, and eco-friendly products are just some of the areas where new ideas are being developed. Who knows what the next great invention will be
1. What does the camera help us do
