1 . The Mona Lisa is the famous Leonardo da Vinci painting of a woman with a mysterious smile. This week, the painting gave up a secret.
Scientists using X-rays to examine the chemical structure of a small part of the painting discovered a technique Leonardo used in the work. An oil paint used for it was a special, new chemical mixture, which suggests that the Italian artist was in an experimental mood when he worked on the painting in the 16th century.
“He loved to experiment, and each of his paintings is completely different technically,”said Victor Gonzalez, a chemist who has studied the chemical element (成分) of several works by Leonardo and other artists. The researchers found a rare lead compound (铅化合物) — plumbonacrite, in Leonardo’s first layer of paint. The discovery proved that da Vinci most likely used lead oxide to thicken and help dry his paint. The paint in the study is about the thickness of a human hair, lying in the top right area of the painting.
The scientists looked into its atomic structure using X-rays, moving particles at the speed of light, permitting researchers to look deeper into the paint structure. “ Plumbonacrite is really a fingerprint of his recipe, as it’s the first time we can chemically confirm it,” Gonzalez said.
Dutch artist Rembrandt may have used a similar mixture when he was painting in the 17th century. Gonzalez and other researchers have found plumbonacrite in his work, too. Leonardo is thought to have put lead oxide powder, which has an orange color, in the oil to make it thicker and dry faster. “What you will get is an oil that has a very nice golden color,” Gonzalez said. “It flows more like honey.”
But the Mona Lisa — said by the Louvre to be a portrait (肖像) of Lisa Gherardini, the wife of a Florentine silk businessman — and additional works by Leonardo still have other secrets to tell. “What we are saying is just a little brick in the knowledge,” Gonzalez said.

4 . The sharing economy is a trend that has been growing in recent years. This economy is based on sharing resources, such as cars, homes, and even clothing, rather than owning them outright. Some popular examples of the sharing economy include Uber, Airbnb, and Lyft.
The sharing economy has several potential benefits. For one, it can help reduce waste and increase sustainability(可持续性), as resources are being used more efficiently. Additionally, it can help provide more affordable options for consumers, as well as create new sources of income for people who may not have had access to traditional job opportunities.
However, there are also potential drawbacks to the sharing economy. Many of the workers in the sharing economy are considered independent contractors, which means they are not entitled to the same benefits and protections as traditional employees. Additionally, there have been concerns about safety and insurance coverage for both the workers and consumers using these services.

6 . How do you spend your spare time? There will be different answers to it. Most people in Poland(波兰) have their own ways of spending free time. Sometimes they just want to have a rest, but they try to do something more pleasant most of the time. They have many different hobbies, which help them to get away from their everyday problems and spend their free time happily.
Many Polish(波兰的) people like travelling. They look for new places that they have never been to and add new and exciting experiences to their journey. Some of them like to climb mountains, others like to go to the sea or a lake to swim, because these can make them get exercise and are good for their health.
Many Polish people also like to watch sports in their free time. They are usually crazy about football, and football is regarded as the Polish national sport. Many football fans may support a certain team, so they go to watch every match of the team they support, and they buy many things that have any relation with the team. Watching a sport and doing it are both good ways to relax.
In addition, doctors say that doing sports is very good for the health. Many people in town, especially young men, often go to the gym to attend the exercise classes to keep fit.
Besides these ways, Polish people have many other ways to spend their free time. And they really enjoy their free time.
