1 . Antibiotics, which can destroy or prevent the growth of bacteria and cure infections, are vital to modern medicine. Their ability to kill bacteria without harming the patient has saved billions of lives and made surgical procedures much safer. But after decades of overuse, their powers are fading. Some bacteria have evolved resistance, creating a growing army of superbugs, against which there is little effective treatment. Antimicrobial (抗菌的) resistance, expected to kill 10 million people a year by 2050 up from around 1 million in 2019, has been seen as a crisis by many.
It would be unwise to rely on new antibiotics to solve the problem. The rate at which resistance emerges is increasing. Some new drugs last only two years before bacteria develop resistance. When new antibiotics do arrive, doctors often store them, using them only reluctantly and for short periods when faced with the most persistent infections. That limits sales, making new antibiotics an unappealing idea for most drug firms.
Governments have been trying to fix the problem by channeling cash into research in drug firms. That has produced only limited improvements. But there is a phenomenon worth a look. Microbiologists have known for decades that disease-causing bacteria can suffer from illnesses of their own. They are supersensitive to attacks by phages, specialized viruses that infect bacteria and often kill them. Phages are considered a promising alternative to antibiotics.
Using one disease-causing virus to fight bacteria has several advantages. Like antibiotics, phages only tend to choose particular targets, leaving human cells alone as they infect and destroy bacterial ones. Unlike antibiotics, phages can evolve just as readily as bacteria can, meaning that even if bacteria do develop resistance, phages may be able to evolve around them in turn.
That, at least, is the theory. The trouble with phages is that comparatively little is known about them. After the discovery of penicillin, the first antibiotic, in 1928, they were largely ignored in the West. Given the severity of the antibiotic-resistance problem, it would be a good idea to find out more about them.
The first step is to run more clinical trials. Interest from Western firms is growing. But it is being held back by the fact that phages are an even less appealing investment than antibiotics. Since they are natural living things, there may be trouble patenting them, making it hard to recover any investment.
Governments can help fun d basic research into phage treatment and clarify the law around exactly what is and is not patentable. In time they can set up phage banks so as to make production cheaper. And they can spread awareness of the risks of overusing antibiotics, and the potential benefits of phages.

2 . Ads, news, movies, TV shows, and many other types of media all want you to accept their messages at face value. However, you should look beneath the surface and ask questions to decode what the media message is really saying. You need to ask yourself two basic questions: Who is the source of the message? How is it trying to get your attention?
Question 1: Who is the source of the message?
(Picture A) Knowing who is responsible for a message can reveal its true intention, as well as any possible prejudice. Just take the picture above as an example. Why are we asked to ban the impacts? Don’t forget that the source at the bottom plays a part. If, sometimes, the source isn’t clear, we can look for it by checking legal documents. |
(Picture B) The obvious part of a message is called the text, which includes any language, imagery, music, or anything else you can see or hear. The implied part of a message is called the subtext, and it’s suggested by the content rather than directly seen or heard. We as individuals then decide how to interpret this subtext based on our personal ideas, world views, and expectations. People with different perspectives might interpret the same piece of message differently. Mind that some media may just take advantage of the prejudice. | (Picture C) Photo control is nearly as old as photography itself, but modern technology has made it common and easy to do. Using photo editing software, almost anyone can make big changes to an image, from adjusting colors and lighting to adding and removing content. That’s why you should always keep a critical eye on images in the media. Some media may hold back or overstate information, like an advertisement that makes the products appear more effective than they really are. | (Picture D) Social media users can also give themselves a digital transformation with a little effort. They can make themselves look however they like in just a few moments. But since these edited images are presented as reality, they can affect our mental well-being. By constantly seeing pictures of artificially superb people, some of us may start to believe that these pictures are genuine, and that we can never live up to these unrealistic ideals. This type of harmful thinking can lead to all sorts of mental and emotional health concerns. |
A.the media hope that you can make sense of their true meanings |
B.finding the sources of media helps to form a sensible judgment |
C.text is more important than subtext when we analyze the messages |
D.photography and photo editing software date back to the same time |

3 . Every summer, as a child, I spent with my parents the annual family holiday, flying away from our home in the West Midlands to their birthplace in Ireland.
I enjoyed it, but once, I behaved differently and left home. Package tours and long-distance flights became my idea of a holiday. I then went and ran into an Englishman who also came of Irish stock, and we both felt the urge to renew our knowledge of Ireland.
It was important for us to discover something different from our childhood visits. So that’s how we came to drive along the winding St John’s Point Peninsula (半岛) in Donegal, part of Ireland’s Wild Atlantic Way, to visit a unique part of the 20th-century history — the Donegal Corridor.
When anyone drives to the point where the land runs out, he sees giant white stones fixed firmly in green grass spelling out “EIRE” and “70”, while the Atlantic wind fiercely blows across the headland and the ice-white waves smash into the rocks below. The meaning behind the stones? They date back to the Second World War when St John’s Point was number 70 in a total of 83 Look Out Points (LOPs), observation stations set up and maintained by Ireland all around its coast.
There lies a bit of curious UK-Ireland history. Although Ireland was officially neutral during the war, the Battle of the Atlantic was being fought close to Irish shores, and these LOPs, staffed by local volunteers known as Coast watchers, passed on information on activities connected with the sea and weather fronts to London.
At St John’s Point, we were standing right under the Donegal Corridor, a long narrow area of airspace in which Ireland ensured safe passage during World War II to planes in the RAF (Royal Air Force) from bases in the UK-governed North of Ireland. The stone markings acted as reference points to aircrews.
Standing on this rough area of land surrounded by the wild and windy ocean brought home to us the conditions in which the Coast watchers and aircrews in the RAF cooperated in a shared history.
I revolted against my family tradition that summer, and I fulfilled my aim of discovering something new and absorbed all Donegal has to offer: empty golden beaches, mysterious ancient stone circles, folk music and crafts, and tasty food. I had fallen in love with Ireland all over again.

4 . Paris has long been at the heart of the history of flight. It is where the Montgolfier brothers went up in the first hot-air balloon in 1783, and where Charles Lindbergh completed the first one-person transatlantic areophane journey in 1927. Next year, if all goes to plan, Paris will witness the birth of another industry

Buy Now, Pay Later Spending
Buy now, pay later(BNPL) spending is expected to rise to record levels this holiday season. With so many young “buy now, pay later” shoppers already in debt from this short-term financing tool not requiring interest, questions emerge: Why do these shoppers use such a tool? And what risks does it pose to their budgets in the months
The many Generation Z and millennials (typically around 40 years and younger) tend to use this short-term financing,
