The story of paper is a great one. Paper is one of the four great inventions of ancient China, and it changed the world a lot. Before paper was invented, people used many different things to write on. Some wrote on animal bones and stones. Others used bamboo slips or silk cloth. But bamboo slips were heavy, and silk was very expensive.
Around 105 AD, a Chinese man named Cai Lun improved the way of making paper. He used cheap materials like tree bark, bamboo and old cloth to make paper. This kind of paper was light, cheap and easy to write on. Soon, it spread across China. Later, paper-making technology went to other countries in Asia, and then to Europe.
Today, paper is still very important in our life. We use it to read, write and draw. We can also see it in many other things, like books, newspapers and boxes. But now, people use less paper because of the Internet. We read news on computers and send messages on phones. However, paper is still a great invention, and it will always be important to humans.

三、阅读理解
Different people have different ideas about the best ways to travel. It all depends on how far you go, how much money you have and what you want to see.
If you’re going to a place that’s thousands of kilometers away, flying is the smartest choice. Planes are the fastest means of transport. You can leave in the morning and arrive at your destination in the afternoon. But you have to get to the airport at least two hours early for check-in, and plane tickets are not cheap, especially during holidays like the Spring Festival.
For travelling between nearby cities, high-speed trains are perfect. They are faster than regular trains and cheaper than planes. You don’t need to get up too early, and you can walk around on the train. Many high-speed trains have comfortable seats and even free water for passengers.
If you want to travel slowly and enjoy the beauty of the countryside, taking a bus is a good idea. Bus tickets are the cheapest of all, and buses go to many small towns that trains and planes can’t reach. But buses are usually slower and sometimes they may be late because of traffic jams.
For short trips in a city, walking or riding a shared bike is the best. They are free or very cheap, and you can move freely through the streets. You can stop to visit a small shop, taste a local snack or take photos of old buildings anytime you like.
11.What is the smartest choice for a long trip of thousands of kilometers
A．Taking a bus. B．Flying.
C．Taking a high-speed train. D．Driving a car.
12.What do you have to do early if you take a plane
A．Buy a shared bike. B．Taste local snacks.
C．Get to the airport for check-in. D．Go to a small town.
13.Why are high-speed trains perfect for nearby city travel
A．Faster than regular trains and cheaper than planes.
B．The slowest and the cheapest.
C．Can reach all small towns.
D．Have no comfortable seats.
14.What is the advantage of taking a bus to travel
A．Always on time. B．Tickets are the cheapest.
C．Faster than planes. D．No traffic jams.
15.Which way is best for a short city trip
A．Flying or taking a train. B．Driving a car or taking a bus.
C．Walking or riding a shared bike. D．Taking a high-speed train or a plane.

8. had a power cut made me very worried

9. how to increase speed
