Even small amounts of processed meat can greatly raise your cancer risk, the World Cancer Research Fund (WCRF) writes. The WCRF update their guidelines every decade, and in this one, they outline three main problems: tobacco, red processed meat, and alcohol (酒精).
No smoking
Avoid alcohol
Decades ago, people thought that you could enjoy alcohol in low to moderate quantities without causing a health risk. Recent research seems to suggest that even in low quantities, drinking alcohol can greatly increase, your risk of cancer.
Red meat
The list wouldn’t be complete without red meat. As other studies before it, the WCRF report further emphasizes that red meat is also associated with an important rise in cancer risk, especially processed red meat. 39.
The findings don’t necessarily offer something -they just repeat what mountains of research are already saying: if you want to avoid, cancer, you need to eat more things that are good for you, less of the things that are harmful to you, and be at least somewhat physically fit.
A.Yes, even little drinking is bad for you. |
B.A smoking area is planned for people who want to smoke. |
C.The first thing you should do is give up smoking (if you do smoke). |
D.However, in the modern world, that seems to be increasingly difficult. |
E.Let me spell that out a different way: bacon and sausages are bad for you. |
F.The WCRF report focuses on finding the causes of cancer and how to avoid them. |
G.Besides affecting physical health, red meat also does harm to one’s mental health. |
Should martial arts be part of the school curriculum (课程)? In the United States and most of Europe, self-defense is not taught at schools. Yes, schools have after-school clubs with trainers from both inside and outside the school using the gyms and classroom to teach a big range of martial arts, but schools very rarely have it on their curriculum, let alone as a main subject.
But after new research that shows that obesity (肥胖) levels are still rising in the first world at a surprising rate, some are suggesting that martial arts may help fight obesity, and also help children become better adapted to the wider world in terms of self-defense and discipline (自律).
Martial arts provide not just a physical work out, but also a chance to develop self-defense skills while training both the body and mind to be disciplined and mindful. Studies have shown that there is a significant connection between practicing martial arts and self-esteem (自尊). Through the arts, students can develop discipline, and cultivate respect for different cultures-something even more important than ever before in our increasingly divided societies. Martial arts also strengthen muscles,improves flexibility and balance. Everyone knows that with better physical health, come better, happier lives.
However, some have been keen to point out that yes, martial arts in every school would be great, but finding those who are trained and qualified (合格的) to teach martial arts could probably prove to be challenge. They believe it is a chicken and egg situation, where without compulsory (强制的) curriculum of martial arts, those who are good at it may never find themselves in a dojo (武术馆) to find out. But to bring it to everyone you need experienced trainers who can teach the martial arts without fear of mishap (不幸事故) or physical damage.

Ridley Scott’s famous war film “Napoleon (拿破仑)” is a series of successful battles looking for a better movie to connect them. Once again, Scott’s craftsmanship (技艺) is on show here, but it’s in service of a deeply shallow screenplay. A great actor is reduced to a ghostly presence in the middle of the movie, and his partner, the character who needs to give the film a beating heart, comes off as flat and hollow.
One of the problems is that the film script tries to put a lot of life into the running time of a single film. Naturally, it opens during the French Revolution, as Napoleon climbs up the political ladder of France with his war talents above all else.
Another part of the problem is that Kirby, the leading actress never really understands what to play with Josephine, a mysterious celebrity (名人) who becomes too much of a mirror for Napoleon. She couldn’t give Napoleon a son, which resulted in their break-up.
Was Napoleon the kind of world leader whose own unsafety resulted in killings we have seen in history? That’s here in a few places, but Scott is uninterested in making any sort of statement about Napoleon or men like him. A very just-the-facts approach of “Napoleon” is incredibly disappointing for a filmmaker who usually finds so much depth in the stories he tells. Worst of all, by the time “Napoleon” gets to Waterloo, we don’t know much more about the main character than we did when we came in. That’s a problem.
Having said that, the wonderful war scenes in “Napoleon” may be enough to prove its existence for fans of historical war films. Whether its bloodied bodies breaking through ice or waves of soldiers rushing into battle, “Napoleon” has some fantastic battle scenes. Maybe the point is that Napoleon Bonaparte was only truly alive when surrounded by so much death.

B.The achievements of Napoleon Bonaparte. |
C.The wars Napoleon Bonaparte fighting in. |
D.The reason for Napoleon Bonaparte’s aliveness. |

Soda bottles and sour cream containers—these plastics typically arrive at recycling plants mixed together in the same bin. But because they are made of different monomers (单体), they must be sorted into different streams before they can be melted to make new products.
“Until about a year ago, everybody thought the only thing you could do is take a plastic, break it back down to a monomer and then re-form it,” says Sanat Kumar, a chemical engineer at Columbia University. To seek new solutions to old recycling problems, his team had to solve a fundamental chemical difficulty: when different plastics are melted together, their various monomers tend to separate from one another. They have developed a process that allows different kinds of plastic to be recycled together. Their findings, reported recently in Nature, could give new life to many items that end up in landfills.
The new process solves this problem by adding chemicals called universal dynamic cross-linkers (交联剂) to the mix. Just as soap brings together oil and water, which creates a bridge, allowing the oil and water to mix together and form a stable liquid, these cross-linkers(when applied under heat)form covalent molecular bonds (共价键) that attach the diverse monomers together. These materials can then be melted and remade again and again because the cross-linkers can break and re-form their bonds.
The researchers hope the technique could eventually help handle more plastic waste—but it’s not yet cheap enough to be widely used at existing recycling facilities. Still, Kumar wishes it would be one way to help recyclers address the plastic waste crisis. “The plastics problem is huge,” he says, “and you’re going to have to look for multiple solutions.”

Authors are upset after tech companies started using their books to train artificial intelligence without letting them know or seeking their permission. They worry about copyright and loss of income, among other issues.
According to CNN, the system is called Books3, and according to an investigation by The Atlantic, the system is based on a collection of pirated (盗版的) e-books including all genres, from fiction to poetry. Books help generative AI systems with learning how to communicate information.
The Atlantic article notes that some of the text that’s training AI on how to use language is taken from Wikipedia and other websites. But high-quality generative AI requires higher-quality input than what is usually found on the internet — that is, it requires the kind found in books.
Many authors apparently don’t view the use of their books to train artificial intelligence as an honor. Rather, it’s a shortcut that robs them of their due, they say. CNN reported that Nora Roberts, who writes romantic novels, has 206 books in the database — “second only to William Shakespeare.” “The database is all kinds of wrong. We are human beings, we are writers and we are being exploited by people who want to use our work, without permission or compensation (赔偿金), to ‘write’ books, scripts, essays because it’s cheap and easy, ” she said in a statement to CNN.
Not everyone is upset, however, by use of their work to train AI. Ian Bogost, author of some popular books, wrote a column for The Atlantic. Bogost claims that successful art is beyond its creator’s plans, noting that an author cannot accurately predict a book’s audience. “To complain this unexpected use for my writing is to decline all of the other unpredictable uses for it. Speaking as a writer, that makes me feel bad.”
1.What contributes to some authors’ dissatisfaction with Books3?A.It is unable to train AI. |
B.It uses their works illegally. |
C.It fails to improve their income. |
D.It sells books without permission. |
A.The reason it was created. |
B.The high quality it possesses. |
C.The benefit it has brought. |
D.The bond it has with Wikipedia. |
A.Made fun of. | B.Caught up with. |
C.Taken advantage of. | D.Looked down upon. |
A.It’s necessary to predict a book’s audience. |
B.Being involved in Books3 is hardly an honor. |
C.Good art should be limited to creators’ plans. |
D.It’s acceptable for books to be used to train AI. |
