It doesn’t impress like George Washington’s plantation on the Potomac, but Lincoln’s home in downtown Springfield, Illinois,     1     （prove）irresistible to visitors since it opened to the public. Beautifully restored（修复）to its 1860 appearance, the house was Abraham and Mary Lincoln’s home for 17 years. In 1844 they bought it     2     $1,200 and some land from Charles Dresser, who performed their     3     （marry）ceremony in 1842.

When the house was built, it was much     4     （small）than it is today. Mary’s niece wrote, “The little home     5     （paint）white.” It was sweet and fresh. Mary loved it. She was extremely pretty, and her house was a reflection of     6     （she）, everything in good taste and in perfect order.

Although Mary loved flowers,     7     she nor her husband was known as a gardener. A long- time neighbor said they never planted trees and only kept a garden for one year. Mary’s sister, Frances Todd Wallace, often came over     8     （plant）flowers in the front yard.

    9     Lincolns enlarged the house to a full two-story in 1856 to meet the needs of their growing family. Three of the four Lincoln sons were born here. After Lincoln was elected President of the US in 1861, they rented the house and     10     （sell）most of their furniture.

3 . You’ve got mail…and it’s a postcard

Paulo Magalhaes, a 34-year-old Portuguese computer engineer, loves to open his mailbox and find a brightly colored picture of Rome’s Colosseum. Or Africa’s Victoria Falls. Or China’s Great Wall.     1    

“I often send postcards to family and friends.” he says to China Daily, “but you can imagine that after a while, you never receive as many as you send, and you realize that not everyone is into it.     2    ” Seeking other like-minded souls, however, Paulo started looking in a somewhat unlikely place: online. Many would say the Internet is a place for people who have given up on the traditional postal service, but Paulo’s hunch(直觉)paid off.

Today his hobby has developed into the website postcrossing.com, a social network that has grown to 575,217 registered users in 214 countries and regions since he started it 10 years ago.     3    Running the website has almost turned into a full-time job.

Language is certainly a barrier for many people. For postcrossing to work worldwide, a common communication language is needed so that everyone can understand each other. As cool as it may be to receive a postcard written in Chinese, the concept doesn’t work if one doesn’t understand it.     4     So a common language is required and in postcrossing that’s English since it’s widely spoken.

“Many people in China have limited exposure to English.     5     That said, we know of many postcrossing members, including Chinese, who have actually improved their English skills through their use of postcrossing,” Paulo says.

5 . 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.

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.
