【推荐1】For late 19th-century North Americans and Europeans, a display of tableware (餐具)could reveal much about someone’s social position, as the wealthy took great care to get different kinds of forks for everything. Before the 18th century, people of all classes usually ate with a knife and a spoon.

The fork’s path to the table was hard-won and slow. In ancient Egypt, Greece, and Rome, forks were used for slicing food into pieces or lifting meat from a pot or fire.

Following a reduction in size, the fork appeared to have entered dining areas in the courts of the Middle East and Byzantine Empire by the eighth and ninth centuries, and became common among wealthy families there by the tenth century. Early in the 11th century, it appeared in various pieces of European art. In the late 11th century, St.Peter Damian from Ostia wrote about a Byzantine princess who used forks and regarded her dying of a disease as punishment for such “luxury”.

The fork’s slow conquest of Europe was carried out from Italy. Motivated by the same concerns for hygiene(卫生)，forks were bought by wealthy Britons，inspired by Queen Victoria, who regarded fork use as a sign of good manners.

The fork’s introduction to North America dates back to 1633, when John Winthrop, a founder of the Massachusetts Bay Colony, was gifted a set of forks. The Industrial Revolution strengthened the fork’s presence on dining room tables as production of flatware became less expensive. Writing in 1896 inSocial Eriquere，Maud C. Cooke declared the fork had finally conquered the knife in America and “any attempt to give the knife importance at table is looked upon as an offense(冒犯)against good taste.”

【推荐2】The Golden Gate Bridge is a well-recognized landmark in the United States. It spans (横跨) the Golden Gate Strait — a mile-wide stretch of water that connects the San Francisco Bay to the Pacific Ocean. The Golden Gate Bridge is one of the most beautiful bridges in the world. It is also one of the tallest.

The idea for a bridge across the strait had been around for many years, because San Francisco suffered from its isolated location. Planning for the Golden Gate Bridge began in 1916, but the design underwent many changes before construction finally started in 1933.

Joseph Strauss was the chief engineer in charge of the bridge project. However, he had little experience with the construction of suspension bridges (吊桥). For this reason, other engineers, architects, and designers made great contributions to the design and construction of the bridge. For example, the bridge owes its art deco (装饰派艺术) style and distinctive orange color to the architects Irving and Gertrude Morrow. Charles Alton Ellis did much of the technical work necessary to build the bridge.

It was not easy to get the project started. Financing had to be found, and there was much opposition to the very idea of a bridge. The US Navy, for example, feared, that a bridge would block ship traffic. The Southern Pacific Railroad, which ran the ferry fleets (轮渡船队), feared competition from the bridge. Many experts did not believe that it would be possible to build such a long bridge under such difficult circumstances. There are strong currents and heavy winds on the bridge site, which made construction dangerous.

The construction of the bridge finally began in 1933. The construction work set new standards for safety — workers were among the first required to wear hard hats, and a safety net saved the lives of nineteen men while the bridge was built. The Golden Gate Bridge was completed in 1937, when the bridge was opened to pedestrians (行人). It was opened to cars one year later. The bridge was finished ahead of schedule and cost much less than originally budgeted.

Because the Golden Gate Bridge is the first sight for many people arriving in the United States by ship, it is sometimes called the “Statue of Liberty” for the West Coast.

【推荐3】A castle was the fortress(堡垒)and home of a king or nobleman.

Most of the castles we think of today were built in Europe. They were constructed from about 1,000 AD to about 1,500 AD, during a period known as the Middle Ages.

Castles played an important role after the fall of the Roman Empire. When a king granted land to nobles, the nobles promised in return to serve the king and provide him with soldiers. Nobles built castles on the lands given to them. But some nobles simply claimed land as their own and built a castle on it. That was asking for trouble. There were many power struggles between nobles and kings, and among the nobles themselves.

A typical stone castle had several main parts. At the centre of the castle was a tall and very strong building called the keep. This is where people in the castle made their last stand if the outer defences failed. The keep was set in a courtyard, where there were workshops, stables, and a kitchen.

High, thick walls surrounded the keep and the courtyard. Strong, round defensive towers stood at the corners of the walls. Guards walked along the tops of the walls and towers.

Many stone castles were surrounded by a wide ditch called a moat. Some moats were filled with water, but many were not. The only way into the castle was across a wooden drawbridge over the moat. If enemies attacked, the defenders raised the bridge. Then they lowered a heavy iron-and-wood barrier called a portcullis to block the entrance to the castle.

A well-built castle was a pretty safe place to be. Attackers had a hard time getting in. But they still had some options. They could go over the walls using ladders. They could smash (撞碎) through the walls or doors. Or they could dig under the walls and try to get part of the wall to fall down. If none of those things worked, they could just camp outside until the defenders ran out of food.

Attackers sometimes brought large machines called siege engines with them to break through castle doors or walls. This was a heavy wooden beam with a metal cap. In the early 1500s, cannons entered wide use in warfare. Cannonballs could dig into the base of stone walls and weaken them. The walls then fell under their own weight. As a result, castles were no longer needed.

【推荐2】The Mysterious World of Deep-Sea Creatures

The deep sea remains one of the least explored and understood environments on our planet. Lying below the sunlit upper layers of the ocean, the deep sea is a region of permanent darkness, freezing temperatures, and massive pressure. Yet, life thrives (茁壮成长) here in some of the most astonishing ways.

* The Black Dragonfish *

Residing at dephs of up to 2,000 meters, the black dragonfish is a predator with a thin and long body and sharp teeth. What makes it unique is its ability to produce its own light, a phenomenon known as bioluminescence. This helps it attract prey (猎物) and communicate with potential mates.

* The Giant Squid *

Long a stuff of legends and tales, the giant squid, which occasionally attacks whales, can reach lengths of up to 43 feet. Its massive eyes, the size of dinner plates, allow it to detect weak light in the deep dark waters. Encounters with this enormous creature are rare, and much of its life remains unknown.

* Tube Worms at Hydrothermal Vents *

In the depths of the ocean, hydrothermal vents (热液喷口) shoot superheated water packed with minerals. Around these vents, communities of tube worms thrive, reaching lengths of up to 2 meters. They possess no mouth or digestive system; instead, bacteria inside them process the minerals from the vents to produce energy.

Modern technology has enabled humans to explore deeper into the ocean than ever before. Using remotely operated vehicles and deep-sea submersibles (潜水器), scientists can now study these creatures in their natural habitats, uncovering secrets that could hold the key to understanding life’s adaptability.
