3 . There has been a very serious decline in the numbers of shallow-water fish as a result of overfishing. People still want to eat fish, so the fishing industry must look at other sources, especially the deep waters of the Atlantic.     1    

Conservation measures will have to be put in place if these deep-sea fish are to survive. Research on five such species shows that numbers have declined by between 87 percent and 98 percent.     2     Many species could well disappear completely if the present trend continues. These are species that have been swimming in our oceans for hundreds of millions of years.

The problem is emphasized by the fact that the decline in numbers happened in less than twenty years. Deep-sea fish take a long time to reproduce and normally live for many years.     3     The average size of such fish also declined, with one species showing a 57 percent decline in average size. This is of particular concern, as large fish tend to produce more offspring than small ones.

    4     The deep-sea species have been caught as if they were the fast-breeding (快速繁殖) fish like sardine and herring. It is like killing elephants as if they reproduced at the same rate as rabbits.

The damage done by overfishing goes beyond the sea environment. Millions of people make a living in the fishing industry.     5     Measures must be taken to not only conserve ecosystems, but also sustain livelihoods and ensure food security.

4 . The United States rose to global power on the strength of its technology, and the lifeblood that technology has long been electricity. By providing long-distance communication and energy, electricity created the modern world. Yet properly understood, the age of electricity is merely the second stage in the age of steam, which began a century earlier.

"It is curious that no one has put together a history of both the steam and electric revolutions." writes Maury Klein in his book The Power Makers, Steam, Electricity, and the Men Invented Modern America. Klein, a noted historian of technology, spins a narrative so lively that at times it reads like a novel.

The story begins in the last years of the 18th century in Scotland, where Watt perfected "the machine that changed the world". Klein writes, "America did not invent the steam engine, but once they grasped its passwords they put it to more uses than anyone else. "

Meanwhile, over the course of 19th century, electricity went from mere curiosity to a basic necessity. Morse invented a code for sending messages over an electromagnetic circuit. Bell then gave the telegraph a voice. Edison perfected an incandescent bulls that brought electric light into the American home.

Most importantly, Edison realized that success depended on mass electrification, which he showed in New York City. With help from Tesla, Westinghouse's firm developed a system using alternating current, which soon became the major forms of power delivery.

To frame his story, Klein creates the character of Ned, a fictional witness to the progress brought about by the steams and electric revolutions in America during one man's lifetime. It's a technique that helps turn a long narrative into an interesting one.

8 . The integration of artificial intelligence (AI) in educational technology (EdTech) has brought incomparable convenience and efficiency to classrooms worldwide. However, despite these advancements, it is crucial to recognize the challenges these AI-driven tools pose to the autonomy and professional judgment of instructors.

One of its primary concerns is the depersonalization of instruction. These tools often rely on pre-packaged digital content and standardized solutions, leaving insufficient room for instructors to tailor their teaching methods. Each student possesses unique characteristics. Instructors, armed with their wealth of experience and knowledge, are best positioned to tailor their approaches to these individual needs. However, AI-driven tools restrict their ability to do so effectively, resulting in a one-size-fits-all approach that fails to inspire students to reach their maximum potential.

EdTech companies offer step-by-step solutions to textbook problems. These are intended to act as study aids. However, some students employ this feature as a means to merely copy solutions without comprehending concepts. Consequently, instances of cheating on assignments and exams become widespread. While these tools may offer convenience, students may use external resources or cooperate with others during quizzes, affecting the honesty of their learning outcomes.

The implications of this depersonalization and the increase in academic dishonesty are far-reaching. By decreasing the role of instructors as facilitators of meaningful educational interactions, we run the risk of preventing the growth of critical thinking and problem-solving skills among students. Education should not only focus on knowledge acquisition, but should also develop the ability to analyze, evaluate, and apply that knowledge in real-world contexts. It should help one’s mind grow, not simply memorize information. Through dynamic classroom discussions, cooperative projects, and hands-on activities, instructors play a crucial role in developing these essential skills.

While AI-driven EdTech tools undeniably have their virtues, we must not lose sight of the importance of preserving instructor autonomy and educational experience. Instead of relying only on pre-packaged content and standardized solutions, these tools should be designed to empower instructors to adapt and customize their approaches while taking full advantage of the benefits of technology.

10 . For people who are planning a trip, a visit to a museum might not be the first thing they think of. After all, there are plenty of ways to appreciate the world’s civilization, gain exciting experiences and spend quality time with family and friends.     1    

Museums are where people learn something new, at every age! Are you interested in something specific?     2    . There, you will find yourself drawn in and inspired! Museums are a fantastic place to learn about a region’s history, scientific achievements, major cultural events, and of course, dinosaurs. They also design exhibitions related to visual arts, industrial innovations and anything that inspires an individual to learn about the past and create new paths to the future.

    3     They will surely be an exciting part of the educational experience with the main purpose to expose children to knowledge of various fields and expand their horizons. To achieve that, museums are working to create meaningful and engaging activities, interactive and knowledge-based.

Museums support tourism. They are tourism promoters in small towns and large cities. Museums aren’t a burden on tax revenue (税收) or a separate concern from other city projects.     4    Statistics show that museums support more than 726, 000 jobs in America.

Museums shape communities. They have activities and exhibitions through which visitors can learn about local history. Museums are places where a shared heritage is celebrated and a collective identity is formed. They provide an interesting public space where people meet and talk to each other.     5
