“Dreams may be more important than sleep. We all need to dream,” said some scientists. Dreams take u1. about one quarter of our sleeping time. People may have several dreams each night.

Scientists in Britain and the United States have made a new kind of enzyme(酵素)that eats plastics. With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.
The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.
The researchers made the discovery while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨基酸). It made the natural enzyme's plasticeating abilities work faster and better.
John McGeehan, one of the lead researchers, said, “We've made an improved enzyme. It's better than the natural one. And we are trying to make more improvements to it.” He went on, “The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.”
The team is now trying to make the enzyme break down PET in large quantities(大量地). “We'll_see_that_the_plastic_pollution_may_be_stopped_with_this_technology__However, there is still a long way to go，” John McGeehan added.

《我不是药神》
Ning Hao and Xu Zheng have come together again to produce a new film—Dying to Survive《我不是药神》— as they return to the summer movie season after 12 years.
This time, director Wen Muye joined the team after Ning Hao recognized his talent for showing true themes. It was Ning Hao who handed Wen Muye the play and asked Xu Zheng to act as the leading role. The film is about Cheng Yong, played by Xu Zheng, a medicine salesman who becomes a hero by helping people get cheaper cancer medicine. The 117minute film connects both laughter and tears together, showing up the kindness of one man against the reality of society.
“It's touching because it pays attention to the better side of people, and you can see how society changes, thanks to just one small act of kindness，” said Xu Zheng at the film premiere(首映) at Tsinghua University in Beijing on July 2.
The movie is based on a true story—Lu Yong, who got cancer in 2002, helped more than 1，000 patients get cheaper but unapproved(未经批准的) medicine from India.
Lu was invited to the film premiere after, and he watched the whole film. Lu said the movie shows what will happen when people can't afford imported(进口的) medicine. He agreed with the message at the end of the movie that the situation was being improved thanks to the recent efforts of government.
Actor Huang Xiaoming was also invited to the premiere, and he thought both the acting and the direction were wonderful. “Even though I'm not in the movie, as a filmmaker, I feel proud to watch this piece，” he said.
