Genghis Khan（成吉思汗）remains to this day one of the most successful men to have walked the Earth. Rising from an outcast to be the ruler of the largest land empire to have ever existed, he introduced an alphabet and an official form of money, united a kingdom of tribes at war with each other, and conquered most of the known world. His empire spread from Poland to Japan. It is estimated that one in every 200 men on the planet today is related to Genghis Khan. But there are no accounts of the events that surrounded his death and burial; only a mystery focused around an area known as the Forbidden Zone.
From the time of the Khan's death in 1227 up until 1991 the Forbidden Zone was as off-limits as any place in the world. Shortly after he died, the surviving Mongol leaders ordered a group of 50 fierce families, known as the Uryangqai of the Woods, to occupy this land and kill anyone who entered without permission.
They made exceptions only for the funeral processions（队伍）of the Khan's direct descendants, who were also allowed to be buried there. This extreme degree of secrecy has led many to the conclusion that the body of Genghis Khan himself lies in a tomb somewhere in this zone, along with some of the treasures of an empire vaster than those of Napoleon and Alexander the Great combined. When the U.S.S. R.（前苏联）took over Mongolia in 1924; they killed all the Uryangqai of the Woods just as they tried to erase the memory of the great Khan. The Forbidden Zone -still remained off-limits, however. It wasn't until the fall of the U.S.S.R. in 1991 that entering the Forbidden Zone became possible for scientists and historians. Even today, eight centuries after it quietly rested, the Forbidden Zone has been visited by very few.

【推荐1】The history of writing instruments, with which humans have recorded and conveyed thoughts and feelings, is the history of civilization itself. This is how we know about our ancestors and their life.
The handy sharpened-stone was adapted into the first writing instrument. Around 24, 000 BC, cavemen started drawing pictures with the stone onto the walls of their caves.
Before paper came along, people used clay or wax tablets on which they wrote with sharp objects such as metal sticks or bones. Around 6000 years ago, the Egyptians invented the first paper-like material called papyrus (纸莎草纸). The word “paper” actually comes from the word “papyrus.”
Another writing instrument that remained active in history for long period was the quill (鹅毛) pen. Introduced around 700 AD, the quill was a pen made from a bird feather. Goose feathers were most common.
When writers had better inks and paper and handwriting had developed into both an art form and an everyday occurrence, man’s inventive nature once again turned to improving the writing instrument.
| A．Then something was needed to write upon the papyrus. |
| B．The papyrus became the most popular material at that time. |
| C．Swan feathers were of high quality, being rare and most expensive. |
| D．Bamboo stems were better and much more expensive than goose feathers. |
| E．These were mostly the stems of grass, especially from the bamboo plant. |
| F．This led to the development of the modern fountain pen in the 19th century. |
| G．These drawings showed events in daily life like the planting of crops or hunting victories. |
【推荐2】Perhaps unsurprisingly, buffoonery(滑稽) was one of few careers acceptable for women to pursue in the Middle Age. And it was not uncommon for women to enjoy this career.
However, in the 17th century, comedians were forced to society’s edge as their tendency to truth-telling was no longer tolerated among high society and women, bearing the weight of gender prejudice, were seldom among this career.
This slowly began to change in the mid-19th century when women began to enter the workforce and, in the circus industry, a growing minority of female performers were employed. They promoted the industry’s “New Woman” movement which introduced female performers into the traditionally male stage.
In 1895, among the women breaking the prejudice was Josephine Williams or “Lady Evetta” called the “The Only Lady Clown”.
Williams told The New York Times: “I believe that a woman can do anything for a living that a man can do and do it just as well as a man. All my people laughed at me when I told them that I was going on stage as a clown. But they do not laugh now.”
Despite her being optimistic, the article concluded: “The men in the clown business rather enjoy Miss. Williams’ odd performances but they do not regard her as a serious competitor or believe that any other women are likely to follow her example.”
How wrong they were. In the 1970s, French-born Annie Fratellini openedeh circus school, Académie Fratellini, encouraged by her film-making husband Pierre Etaix.
Fratellini Auguste was recognizable as the clown familiar today. Her unique make-up was made up of a big red nose, tears, a black mouth and shiny decorations fixed to her eyes. When asked whether the character she acted was male or female, she insisted that “clowns have no gender”.

【推荐3】In the American colonies (殖民地) there was little money. England did not supply the colonies with coins and it did not allow the colonies to make their own coins. Only the Massachusetts Bay Colony received permission for a short period in 1652 to make several kinds of silver coins. England wanted to keep money out of America as a means of controlling trade: America was forced to trade only with England as it did not have the money to buy products from other countries. The result during the pre-revolutionary period was that the colonists used various goods in place of money: beaver furs, Indian wampum, and tobacco leaves were all commonly used as substitutes (代替物) for money. The colonists also made use of any foreign coins they could obtain. Dutch, Spanish, French, and English coins were all in use in the American colonies.
Individual states and the Continental Congress (大陆国会) issued paper money. So much of this paper money was printed that by the end of the Revolutionary War it was actually worthless. As a result, trade-in goods and the use of foreign coins were still common during this period.
By the time the Revolutionary War had been won by the American colonists, the monetary (货币的) system was in a state of total confusion. To change this situation, the new Constitution of the United States (美国宪法), approved in 1789, allowed only Congress to issue money. The individual states could no longer have their own money supply. A few years later, the Coinage Act of 1792 made the dollar the official currency of the United States and put the country on a bimetallic (双金属的) standard. In this bimetallic system, both gold and silver were legal money, and the rate of exchange of silver to gold was fixed by the government at sixteen to one.

【推荐1】Women make good spies. This is because women are good at multitasking. They are also good at reading other people’s emotions. As a spy, this can help with gathering information. Both of these skills are also useful as a mother. That might be the biggest reason why women make good ones. Here are the stories of four famous female spies.
Harriet Tubman
Harriet Tubman played an important role in the Underground Railroad. The network led enslaved (被奴役的) people in Southern states to freedom in Northern states. Tubman was also a spy, according to History.com. She was a soldier and spy for the Union Army in the Civil War. Her duties included forming a spy ring, gathering information about the Confederacy (邦联) and mapping the area. She also led a military battle in 1863. She became the first woman in the U.S. history to do this.
“Jen”
Jen is a female Central Intelligence Agency (CIA) researcher. Her real name is kept secret for her protection. The CIA collects security information for the United States. Jen played a big part in finding Osama bin Laden. Jen is tough, and she spent five years looking for him.
Christine Granville
“Christine Granville’s charm and beauty were really important,” says Clare Mulley. She wrote a book about Granville. Granville was fast-thinking, brave and devoted. She once bit her own tongue to fake the symptoms of a disease. This helped her escape the Gestapo during World War II. The Gestapo were secret police for the Nazis. Granville was awarded the George Medal. It is a British award for bravery.
Stella Rimington
Rimington was the first female director of MI5. The organization is the United Kingdom’s intelligence agency. She led the office between 1992 and 1996. She too was a mother. She no longer works for MI5. Now, she writes spy novels.

【推荐3】Sometimes called “Earth’s twin,” Venus is similar to our world in size and composition. The two rocky planets are also roughly the same distance from the sun, and both have an atmosphere. While Venus’s cold and unpleasant landscape does make it seem far less like Earth, scientists recently detected another striking similarity between the two, the presence of active volcanoes.
When NASA’s Magellan mission mapped much of the planet with radar in the 1990sit revealed an unexpectedly youthful surface-there were surprisingly a few craters (火山口)which suggested active geologic (地质的) processes. Although few missions have visited Venus since then, researchers have continued to mine the collection of data from.
Using this decades-old data, planetary scientist Robert Herrick discovered that a Magellan. volcano called Maat Mons is alive with volcanic activity. In this case, lava(岩浆)flows that moved for eight months during an imaging cycle from 1990 to 1992, according to a study published in Science in 2023. The findings are the first real evidence that volcanoes have erupted on Venus during modern times.
What’s more, volcanic activity on Venus could be even more common and dramatic than on Earth. A study published in JGR Planets in 2023 mapped out enormous potential volcanic features on Venus’ surface, and there’s a good chance that some of them could be active today. On top of that, another 2023 study, also in JGR Planets, found that the very high surface temperature on Venus, over 900 degrees Fahrenheit, allows lava flows to slowly leak out.
A list of new missions are headed to Venus over the next decade, including NASA’s Veritas mission, which aims to map the planet’s surface to better understand its geologic history. These projects should settle the question of how the paths of Venus and Earth divided so sharply, with one becoming a hell and the other able to harbor life, and confirm whether volcanoes are still erupting on the planet today.
1. Why does the writer mention Venus is Earth’s twin in Paragraph 1?| A．To prove a theory. | B．To introduce the topic. |

【推荐1】Traveling by subway can sometimes be quite an adventure, especially during rush hour. There are the times when you have to avoid cups of coffee that could spill (溅) on you. The smells of some passengers’ food are very strong, too. According to the Beijing subway passenger regulations, which went into effect on May 15th, passengers except babies and the sick are no longer allowed to eat or drink on the subway. Violators (违反者) who do not stop after being asked to will be asked to get off. The violation will also be recorded in the violators’ credit record.
Some support the rule. The reason is that the smell of food and drink can annoy other passengers. “The smell of food fills the carriage, causing people discomfort, especially in the hot summer, Besides, eating on the subway produces rubbish. And on subway trains, people often spill their drinks,” said Zheng Yiou, 17, a student from Hefei.
However, others question this rule. “Some citizens live so far from their work places that they have limited time to have breakfast before they go to work. Eating while they travel saves them time and decreases the chance that they will be late for work,” He Songlin, a 17-year-old student from Chengdu said, “And some people, like those with low- blood sugar levels, get sick if they can’t eat when they must.”
Other Chinese cities like Nanjing and Chengdu have similar regulations. Some foreign cities also ban eating and drinking on the subway. For example, eating and drinking have long been banned on the subway in Washington DC. Singapore fines people who eat or drink on the subway up to 500 Singapore dollars, which is RMB 2,417 yuan.
Chen Yanyan, a professor from Beijing University of Technology, believed we should consider the need of some people to eat or drink on the subway. “Commuters (上班族) and travelers are sometimes too busy to eat. Maybe we could learn from Tokyo, where there are many subway stations equipped with services, allowing passengers to eat and drink,” she said.

【推荐2】A food additive (添加剂) is any substance that is added to food. Many people are put off by the idea of “chemicals in food.” The truth is that all food is made up of chemicals. Natural substances (物质)like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas. Some chemical substances are indeed harmful, but a person who refused to consume any chemicals would find nothing to eat.
The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory-made substances increase the nutritional value of food. Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange. Like “chemical”, “man-made” doesn’t necessarily mean “not fit to eat”.
Food additives are used for many reasons. We add sugar and salt and other things to foods we prepare at home to make them taste better. Food producers have developed a range of additives that stabilize, thicken, harden, keep wet, keep firm, or improve the appearance of their products.
Additives can make food more convenient or nutritious, give it a longer shelf life, and make it more attractive to the consumer, thus increasing the sales and profits of the producers.
Food additives are presently the centre of a storm of serious argument. Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market. Many people feel there’s a risk of eating food to which anything has been added. But food additives are now regulated by the FDA of the federal government, and new additives will go through strict testing before they can be placed on the market. For most people, the chances of developing serious side effects from the long-term use of presently approved (批准) food additives are very small.
1. From the passage we can learn that ______ .| A．it is right to refuse chemicals in food |
| B．all foods have chemical substances |
| C．food additives are harmful to our health |
| D．natural foods are much safer than man-made ones |
| A．Foods without additives can keep a much longer shelf life. |

【推荐3】The "cloud war" is taking place as the dispute between the United States and China about data hacking and computer network security grows stronger. Chinese companies such as Alibaba, Baidu and Huawei are expanding within their country and gaining customers in other countries. They are creating data centers in multiple countries and trying to sell data management services throughout the world.
The increasing competition in cloud computing and storage incurs the new challenge and worries some experts. They are concerned about the safety of data. After all, companies often use the cloud to store important, confidential information and to operate such activities as data-driven machinery, telecommunications, banking and transport systems — including plans for driverless vehicles.
Lee Branstetter is an associate professor of economics at the Heinz School of Policy and Management of the Carnegie Mellon University. He told many multi-national companies "have serious concerns about the protection of their intellectual property （知识产权）."Branstetter said some of these large companies already believe they have lost valuable information.
Sheila Jasanoff is the director of the program on science, technology and society at Harvard's Kennedy School. She called the cloud computing industry "unruly". In other words, the industry is not strictly governed.
"People （in the business） are making rules as they go along or taking advantage of the lack of rules," Jasanoff said. She said cloud computing companies are not clear about what security measures they are promising customers. She is worried that a major accident may happen before governments realize the need for stronger rules in the cloud computing industry. She believes there should be internationally-accepted rules to meet the new challenge. But she does not believe an international agreement will be reached anytime soon.

【推荐1】Recently China’s netizens took to the microblogging site Weibo to passionately critique pictures Of the Great Wall in Suizhong County Liaoning province(辽宁省绥中县).
And rightly so.
The New York Times described the flattened section as a “cement (水泥) skateboarding lane dumped (遗弃)in the wilderness .” Let me explain if you haven’t seen in the photos : smooth concrete（混凝土）covers the top, and battlements (城垛) along the edges were completely destroyed--work done in the name of “conservation. " The Great Wall has been a UNESCO World Heritage Site for decades recognizing China's diverse architectural history. Undoubtedly, this particular “conservation” represents a tragedy for the whole world.
As the tourism industry in China picks up, heritage sites are coming under greater public scrutiny(公众监督). Sites that I have visited such as the Summer Palace, Terracotta Warriors and Yu Garden each see millions of tourists every year. As a result, we have grounds to believe that historic sites do need conservation for fear that the inevitable crowds of tourists will trample (践踏) them into dust.
However ，conservation should not only improve physical accessibility it should also retain the character and enhance the experience. One need not look farther than Badaling or Mutianyu in Beijing. While this Great wall restoration provides significant employment opportunities and mostly protects the wall from destruction, it is not without fault. Many visitors complain of overcrowding , the “fakeness” of gauy (花哨的) new architecture and high ticket prices.
Moreover, there is no comprehensive (全面的) academic publication in any language about the Great Wall. Little scientific knowledge proves the truth of historical and political claims. For instance, UNESCO still claims that the Great wall can be seen from space while China's first taikonaut Yang Liwei stated otherwise.
Unfortunately, the restoration of the Great Wall in Suizhong cannot be changed back to what it was before. Then what can you young people do to support the Great Wall and other historic sites in China? At least it is within your power to learn about the rich history of heritage sites, observe guidelines when visiting them and encourage others to follow your example.
1. According to the New York Times , the restoration of the Great Wall was_______| A．of no importance | B．far from satisfactory |
| C．worth the effort | D．not too bad |
| A．It cost a large sum of money |
| B．It was only focused on physical accessibility |
| C．It was not approved by the loyal government |
| D．It was meant to development tourism industry in China |
| A．it was listed as a UNESCO World Heritage Site several years ago |
| B．it can be found in different provinces of China |

【推荐2】In American schools there is something called Homecoming Day. Many high schools and colleges with a football team have a homecoming game. This can be the most important event of the year except graduation day. Students plan Homecoming Day for many weeks in advance.
Several days before Homecoming, students start to decorate the school. There are signs to wish luck to the team, and many other signs to welcome all the graduates. The members of school clubs build booths（摊位）and sell lemonade, apples and sandwiches. Some clubs help to welcome visitors.
During the day alumni will gather at the school. They like to look for teachers that they remember. Often they see old friends and they talk together about those happy years in school. Many people still come to Homecoming twenty or thirty years after their graduation.
Everyone soon comes to watch the football game. When the game is half over, a band comes onto the field and plays school songs. Another important moment is when the Homecoming Queen or King appears. All the students vote the most popular student Homecoming Queen or King. It is a great honor to be chosen.
Homecoming is a happy day but it is not perfect unless the football team wins the game. Even if the game loses, the students still enjoy Homecoming. Some stay at the school to dance and others go to a party. For everyone it is a day worth remembering.

【推荐3】Trust me, you don’t want to get caught under a tsunami! Tsunamis are one of the world’s most powerful natural forces. They can cause huge amounts of damage.
But do you know exactly what a tsunami is? They are huge, powerful waves in the ocean that grow as they reach the shore. Most tsunamis are actually caused by earthquakes. An earthquake happens when a big piece of the Earth’s crust( 地 壳 ) suddenly moves. When the piece of ocean floor moves, it creates big holes. The water floods in to fill these holes. When the water moves that quickly, it creates a huge wave. This is how tsunamis are born!
Other natural disasters like landslides, volcanic eruptions, and glaciers breaking off can also cause tsunamis. Once the water starts moving because of the force of the disaster, large waves begin to spread. These waves can move very fast. They have been recorded at speeds from 400 up to 500 miles per hour! They can also move across very long distances.
At first, the waves of the tsunami may not seem that tall. That’s because when the waves travel through the deep parts of the ocean, the top of each wave is very short. But as that wave comes near to the coast, it grows in height. Remember, the tsunami travels quickly. If you are sitting on a beach, you may not see the wave coming at first. But when the wave arrives, it will be like a towering wall of water. Some waves are as tall as 100 feet high. The biggest tsunami ever recorded happened in 1958 in Lituya Bay, Alaska. The wave was over 1,720 feet tall, and it wiped out trees, vegetation, and everything else in its way.
As frightening as tsunamis can be, you don’t need to worry too much about them. They don’t happen that often. Only about two tsunamis happen every year. And it is said that serious, really damaging tsunamis only happen about every fifteen years. So don’t worry.
1. Based on the information in the article, which natural disaster is not responsible for causing a tsunami?| A．tornado | B．volcanic eruption | C．earthquake | D．landslides |
| A．2 hours | B．3 hours | C．4 hours | D．5 hours |
