Before there were airplanes, people dreamed of flying. They told stories about flying people. One old story is about a young man named Icarus. He and his father wanted to get away from a bad king. So Icarus’ father made wings, and they used them to fly away. Years ago, people also tried to make flying machines. Most of them did not work. But today, flying is not just a dream. Today, big airlines carry many passengers. But some people enjoy flying in small planes. In 2014, a young man flew around the world. His name is Matt Guthmiller. He was only 19 years old, but he flew by himself. His trip took six weeks. He stopped 25 times in 14 countries. He is the youngest person to fly around the world.

Many people now dream of flying into space. And their dreams may soon come true. Many companies are building space planes. They will take people on short flights to space. Space tourism will be expensive at first. But over time, it should become much cheaper. Then more people’s dreams of flying will come true.

An old man went to a doctor to ask some questions about his wife’s hearing. He was worried that she was going deaf, as she seemed to be having a hard time hearing the old man speak. The doctor suggested a test to find out exactly how bad her hearing was.

“Stand far behind her and ask her a question. If she doesn’t answer, move a little bit closer and ask again. Keep doing this until you can figure out（弄清楚）how far away she can hear.” the doctor said.

The old man then returned home. He was quite excited to finally find a way to this problem. He saw that his wife was cooking dinner. While standing about 15 meters behind her, he asked, “What’s for dinner, dear?” But she didn’t reply. He moved closer, standing about 10 meters away from her. He asked her the same question, but she still did not reply to him. He then moved to 5 meters away and asked her the question again－but once again, she did not reply. Fearing what would happen next, he moved until he was just 1 meter away from her. He asked her one more time, “What’s for dinner, dear?”

His wife yelled back at him: “Why did you ask me so many times? We’re having lasagna（意式千层面）for dinner!”

The world’s longest cross-sea bridge——the 55-km-long Hong Kong-Zhuhai-Macao Bridge （HZMB） opened on Oct 24, 2018. The Guardian described it as one of the “seven wonders of the modern world”.

Construction（建筑工程）on the HZMB began in 2009 and cost about 120 billion yuan. The bridge links Hong Kong and Macao to the Chinese mainland city of Zhuhai.

The HZMB is unique in many ways. It’s designed to have a service life of 120 years, 20 years longer than most bridges.

And it’s not just a bridge, but also part tunnel（隧道）and part island. In one section, the bridge turns into a 6.7-km undersea tunnel that passes through two man-made islands. The tunnel is the world’s longest undersea tunnel for road traffic, allowing large ships to continue passing through the sea area above the tunnel.

The bridge’s engineers had to consider many environmental factors in order to protect the surrounding（周围的）environment while building the bridge. Chinese white dolphins, an endangered species that lives in the area, were a particular concern（关注）.

The HZMB will make it much more convenient to travel between the three areas it connects. It will shorten the travel time from Hong Kong to Zhuhai from four hours to about 45 minutes.

By drawing local cities and regions closer together, the bridge will help in the area’s development. It is expected to drive the economic（经济的）development of Hong Kong, Macao and nine Guangdong cities.

But it is true that kung fu is a big part of Chinese culture. Like most people from the West, I was first introduced to kung fu through Hong Kong action films. Stars like Bruce Lee and Jackie Chan made kung fu popular in the Western world.

However, my own personal interest in kung fu was actually inspired by a hip-hop group. Wu-Tang Clan（武当派）, founded in the early 1990s in New York City, is one of the most influential hip-hop groups in history. In their songs, they sometimes mention philosophical concepts（哲学理念）that come from wudang quan and the Shaolin Monastery. I was just a teenager when I first started listening to Wu-Tang Clan－little did I know that I would actually end up living in China later in my life!

I do not practice kung fu. However, the concepts behind it are quite interesting to me. There is a Bruce Lee that I often think of when I’m struggling with challenges in life. By this, he meant that you should be ready to adapt（调整）and change your attitudes when you face difficulties. I think this is a good way to deal with life.

We all need money, but money doesn’t grow on trees. How can you be s    41    with your money? First, follow one rule. Always spend     42    （little）than you earn. To do that, make a budget.

W    45    it down. Then stick to your budget!

You need     46    （save）some money every month. You may need extra money for an emergency. Also, you may want to buy expensive     47    （thing）such as a new phone or computer. Save money     48    you have enough to buy them. Don’t buy them with a credit card and just make     49    （month）payments. If you do, you     50    （pay）a lot of interest. Then what you buy will be even more expensive! Wait until you have enough money to buy what you want. That’s smart.
