4 . Oil becomes more expensive and difficult to find. It’s becoming less and less, too. Scientists are looking for other energies, including solar (太阳能), wind and even nuclear (核能) power.

Solar boards (板) catch energy from the sun and turn it into electricity. One of the world’s largest solar power stations is in Germany. What’s more, solar energy produces no waste.

Wind, the fastest growing kind of energy, is another way of collecting energy from the sun. As we all know, Holland is famous for its wind electricity. And it’s also called Windmill Kingdom (风车之国).

Nuclear power produces electricity more cheaply with no carbon (碳) waste. And more countries join the nuclear group. China has built twenty-two nuclear power stations, too.

5 . When we talk about the Vikings, we usually think of the Viking soldiers. They sailed to other countries across the sea and fought with the people there. But in fact, at that time most Vikings stayed in their home countries of Norway, Denmark or Sweden. They lived peaceful lives. Some Vikings lived with their families on farms without any neighbors, but most lived in towns. Towns were often near the sea or a river, so ships could arrive easily. It was an important place for people to buy and sell lots of different objects, including clothes, food, plates, jewellery and many other useful things. So they really did well in trading.

(—From The Vikings)

8 . Do you know the project — Ning-Ning Cooperation(宁宁合作) ? The first “Ning” means Nanjing and the second one is Xining. It is set up to help Xining in education, medical care and so on. Nanjing is a city which lies to the southeast of Xining. It’s about 2000 kilometers away from Xining. Although it is far, moving stories never stop happening.

A girl named Feifei got serious heart problems. The doctor said she was in great danger. It was impossible to save her because of the high sea level (海拔) in Xining. Her family got into the dark when the bad news came. Luckily, they got great help from Nanjing Children’ s Hospital. The excellent doctors tried their best to save the girl. ①They gave her successful treatment(治疗). The responsible nurses also took good care of her. Soon Feifei got better. What’s more, the whole treatment was free. Feifei’s family needn’t pay for it because of this project.

②What a(an) ________ and ________ project it is! Thumb up(点赞) for our country, for Nanjing and for the project!

The C919 is an important kind of plane in China. 130 lucky people experienced its first business flight(飞行) from Shanghai to Beijing on May 28th, 2023. The body of this plane is painted “全球首架” in Chinese and “THE WORLD’ S FIRST C919” in English. There are 156 seats in the economy class(经济舱) and 8 seats in the first class(头等舱). Twenty big screens are in it, too. The seats are the most comfortable and the screens are the clearest. Passengers can enjoy different kinds of delicious foods. They can also lie down easily and have a good rest because it is very spacious.

The first successful business flight of the C919 makes a big difference to China. We have made great progress in Chinese civil transportation.
