1 . For more than half a century, scientists have sought to understand X-rays from space and what they reveal about our galaxy and the universe beyond it. As it turns out, lobsters can help astronomers do just that.

Lobsters (龙虾) have developed specialized eyes to see in their dark habitats located up to around 2,300 feet below the ocean surface. Unlike humans, whose eyes consist of rounded lenses that bend light, lobsters’ eyes depend on reflection. Each of their two eyes is packed with up to 10,000 square-shaped tubes. Each tube is lined with a flat, reflective surface that acts like a mirror to direct incoming light down to the retina (视网膜). This setup affords lobsters a full 180-degree view, compared with humans’ 120-degree vision.

The breakthrough idea connecting lobster eyes to astronomy came in 1978 when Roger Angel, an astronomer at the University of Arizona, drew inspiration from an article on animal vision. Angel envisioned creating instruments imitating lobster eyes to enhance the capture of cosmic X-rays during missions beyond Earth’s orbit. In 1992, researchers from Columbia University ran the first successful X-ray measurements using lobster-eye instruments. It took another 15 years before the tech was adapted for spacecraft missions. “This is a technology that’s been around a long time in astrophysics,” says Scott Porter, an astrophysicist at the NASA Goddard Space Flight Center.

Today, Porter’s team has developed specialized instruments to better understand how solar wind interact with Earth’s magnetic (磁的) field. Researchers pack thousands of tiny glass tubes and then heat and curve them to create a ball shape that can concentrate the X-rays into a singular point. Plus, many of these tools are much lighter and smaller than traditional X-ray instruments, and therefore easier to incorporate into multi-instrument missions.

Porter says that the number of applications for lobster-based instruments have increased in recent years. As projects receive funding, lobster eye instruments may become a key tool in our quest to better understand the vast, mysterious universe.

Traditional Chinese Medicine (TCM) has evolved over thousands of years. It is a comprehensive healthcare system     1     (root) in ancient theory and wisdom.

TCM came into being in the primitive (原始的) society, and its theory     2     (form) during the Spring and Autumn Period. During the Ming and Qing Dynasty, doctors tended to improve it despite pressure and difficulties.

    3     makes Chinese medicine distinct is its emphasis on the balance of vital energy within the body and the recognition of the body as     4     whole. In TCM, individuals often encounter a unique diagnostic (诊断的) approach,     5     involves considering not just symptoms but also the lifestyle of the person. Chinese medicine has a wide range of treatments,     6     (include) herbal medicine, acupuncture (针灸), and dietary therapy, to address both the symptoms and potential imbalances. In fact, TCM doesn’t only treat diseases; it promotes overall well-being by harmonizing the body, mind, and spirit. Medical     7     (professional) advocate that each individual is different, and their health conditions may originate from a     8     (combine) of factors.

Ancient wisdom and modern research have enabled Chinese medicine to find its place alongside Western medicine,     9     an increasing number of people seeking a comprehensive approach to healthcare. As Chinese medicine becomes more     10     (wide) recognized, it not only contributes to individual health but also enriches the global healthcare landscape.

For many years, people have been worried that one day, robots could take their jobs. Now, it    1     (seem) that it may start happening.

ChatGPT is     2     AI chatbot, which is the fastest-growing app based on a    3     (power) language processing model. It had 100 million active users just two months after     4     (it) start. Experts started to worry that the latest chatbots could harm the careers (事业) of anyone who works with information, does research or writes reports. Chatbots are very creative, and can do things that we thought only humans could do. So an increasing number    5     users see this as a business chance. They will start using a chatbot as a staff member that may    6     (compare) to a newly employed graduate in terms of its ability to think. Chatbots work very fast, without     7     (request) a break or pay, and for business people, that’s     8     (extreme) important. Some UK law companies have already realized it     9     started using chatbots to write legal (法律的) letters or provide ideas for legal matters.

However, one of the biggest     10     (problem) with ChatGPT is that it doesn’t know the actual truth about the world — it simply learns information from various resources (资源) but cannot decide on its own what is true or false.
