3 . The story of English language is a story of change.The old English language, or old English, is quite different from Modern English.If we do not study old English, we can’t understand it.Some of the words are the same, but many are not used now.The story of the English language begins some time after the year 400 AD.At this time, some people came to England from North-west Europe.There were many groups of people.They were called Angles (盎格鲁人), Saxons(撒克逊人)and Jutes(朱特人),whose language, old English, is like some of the modern language of North-West Europe.In old English, the ending had many meanings.They showed past time and present time and many other things.In Modern English, most of these endings are gone.This is the biggest difference between Old and Modern English.

4 . Anyone wanting to help the poor may like this idea—recycling aluminum cans in a different way, which is apparently also good for the environment. So you're actually killing two birds with one stone. It goes without saying that recycling aluminum cans can save resources, energy, time and money. People usually save and place aluminum cans in the dustbins, which are then collected and taken away by cleaners, who will finally recycle them in the recycling center. But if you save the aluminum cans, and skip the cleaners, you can save these same cans for something more important—helping the poor. In other words, by doing less, you are giving the environmental cause some new significance.

Here is how to put this idea into action. Take your aluminum cans and place them in a plastic bag. For the dirty ones, rinse them out first. Store the bag of clean aluminum cans. Once you collect about one hundred cans or more, take the cans to the recycle center yourself. There are about eighteen aluminum cans in a pound. And you can receive three to four dollars for one hundred cans. Donate your three to four dollars to the poor or any charity organization of your choice.

By now, you may wonder if your few dollars have really made a difference to the poor. Consider this: Is there any individual or any specific event that is great enough to change the world or decide the direction that history takes? The answer is probably no. What if there were a lot of people who would do the same thing? History shows nothing but the collective will of the whole community. And that will surely be powerful enough to make a bigger difference.

Go to your community or your school and spread your idea. Share your idea and save your aluminum cans with other people. One hundred people can speak louder than one. And the money you make by saving cans can be multiplied by one hundred times. And if more people join in the cause around the world, an even larger difference can be made , and more people in need will enjoy the benefits.

7 . With the infection being brought under control, more and more galleries and museums are reopening. While many museums have been putting exhibitions online, visitors still prefer to enjoy works of art in person. Here are four major art exhibitions that are held offline.

The Palace Museum (Dec. 10—Feb. 15)

The exhibition, Everlasting Splendor which is being held in the Meridian Gate Galleries, marks the 600^th anniversary of China’s imperial palace. Over 400 cultural relics are displayed at the exhibition, reflecting the history of the Forbidden City’s construction, the development of its layout, and how it has been protected and restored in the past decades.

The National Museum of China (Jan. 4—Mar. 29)

The exhibition, A Sail Over Miles, offers a brief review of the ancient Silk Road in ceramics (陶瓷). It guides visitors through the manufacturing, export and shipping routes from the Tang Dynasty to the Qing Dynasty with over 300 ceramic relies, including a pot dug from Nanhai No 1, a Chinese cargo ship dating back more than 800 years. The exhibition also shows Japanese, Korean and British ceramics, reflecting the influence of China’s porcelain-making techniques in local industries.

The Capital Museum (Jan. 1—Mar. 30)

The Capital Museum is to host Man of Infinite Refinement: Special Exhibition on the Paintings and Calligraphy of Su Shi, a calligraphy and painting exhibition on the legacy of Su Shi, an iconic figure of ancient Chinese literature and fine arts. The 78 exhibits on display spans from the Northern Song Dynasty through recent history and cover a range of media, including calligraphy, paintings, documents and rarely seen books.

The National Art Museum of China (Nov. 30—Feb. 10)

On show are nearly 300 objects, including paintings, calligraphy works, carved seals, manuscripts, letters and books. Donation of Rong Geng not only reflects his academic accumulation over the years, but forms the basis for his becoming such a well-rounded scholar in the area of Chinese cultural traditions.

Rong Geng (1894—1983), a scholar of Chinese paleography, educator and connoisseur of antiquities, is little known to the general public. However, his extensive studies of ancient Chinese writings and his former collection of archaic oracle bones and bronzes continue to enrich people’s cultural life. In his lifetime, Rong donated to the State nearly 200 bronze objects, all of which are now housed at numerous public museums and universities.

9 . When whales die and sink to the ocean floor, their bodies -known as whale falls -provide rich nutrients for other creatures of the deep.

Chinese scientists found a whale fall in the South China Sea during a recent scientific research voyage. It was the first time that Chinese researchers had run across this rare type of ecosystem. It was an important finding, showing China's progress in deep-sea exploration technology, Xie said, a professor at Sun Yat-sen University.

During the 22-day deep-sea exploration from March 10 to April 2. 60 scientists conducted 22 dives and successfully completed a number of scientific tasks. The research aimed to gather information about the key processes of typical seamount ecosystems in the Western Pacific: Ocean. The whale fall was found in a seamount 1,600 meters deep in the central South China Sea. Though the whale fall was only about 3 meters long, it was of great importance in understanding the sea ecosystems, Xie said.

There were dozens of white armored shrimp, red shrimp and several eels found near the whale fall. The eels were eating the tail muscles of the whale fall. This shows that the whale died not long ago and that the whale fall was still in the first stage of decomposition and thus had rare value for long-term observation, Xie said.

Like cold springs, whale falls are homes for creatures of the deep. In the northern Pacific Ocean, they have supported the survival of at least 12,490 kinds of organisms—classed in 43 species—and promote prosperity far beneath the surface, according to data from the university.

10 . A new study on the link between chili and dementia(老年痴呆) may bring bad news for spicy food addicts. Researchers have found that eating lots of chili may cause an increased risk of dementia.

The study, led by Zumin Shi, analyzed 4,582 Chinese adults aged 55 and above between 1991 and 2006 and found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. “Chili consumption was found to be beneficial to body weight and blood pressure in our previous studies. However, in this study, we found negative effects on cognition among older adults,” Shi said in a press release published Tuesday.

“Chili is one of the most commonly used spices in the world and particularly popular in Asia compared to European countries,” Ming Li from the University of Southern Australia said in the press release. “In certain regions of China, such as Sichuan and Hunan, almost one in three adults consumes spicy food every day.”

The researchers said people of normal body weight may be more sensitive to chili intake and hence their memory and weight suffer a bigger impact. Worldwide, around 50 million people have dementia, and Alzheimer’s disease is the most common form that may contribute to 60 percent to 70 percent of the cases, according to the World Health Organization. At present, no treatment can cure dementia or change its progressive course.
