2 . For many, Labor Day weekend signals the end of summer and an opportunity to host a socially-distanced barbecue (an outdoor meal). But this national holiday—celebrated every year in the United States and Canada on the first Monday in September—has revolutionary (革命性的) origins.

By the late 19th century, the Industrial Revolution had made working life miserable for people around the world. In many places, workers toiled for at least 12 hours a day six days a week in mines, factories, railroads, and mills. This holiday actually originated in the US on May 1, 1866, in what came to be known as the Haymarket Riot, workers flooded Chicago streets to demand an eight-hour workday.

It would take another conflict in the American Midwest to make Labor Day a national holiday. On May 11, 1894, workers at the Pullman Palace Car Company, a railroad car manufacturer near Chicago, went on strike to protest their low wages and 16-hour workdays. In August 1893, James Kyle introduced federal legislation (立法) to make Labor Day a public holiday, but for ten months the legislation was put on hold. To quiet the strikers and their supporters, the Senate quickly passed the bill on June 22. The bill passed the House four days later and President Grover Cleveland signed it into law on June 28, 1894.

The holiday is more information May Day labor celebrations. Many observers relax at home or head to outdoor recreational activities, such as boating, barbecues, and camping. It may also be marked with fireworks shows and other events. Labor Day has also become associated with retail sales, as many shop owners try to take advantage of the customers’ day off. It is one of the largest sales events of the year. meaning retail employees actually have to work more on this day. Parades are the most common model of celebration, which often feature processions of labor groups.

3 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

With the International Conference on Food Loss and Waste closed on Saturday in Jinan, Shandong Province, the country has sent a signal to     1     world that China will deal with issues concerning food security by reducing loss and waste in agriculture. With the theme of reducing food loss and food waste and promoting     2     (globe) food security, the three-day event     3     (hold) both online and offline attracted more than 300 participants.

The current world grain production is about 2.8 billion tons a year. Therefore, the loss of only one percentage     4     (be) equal to the loss of 28 million tons of food. This can feed about 70 million people.

In recent years, China     5     (make) great progress in controlling loss and waste in food, with main efforts including upgrading facilities and     6     (equip). In Shandong Province, China’s major grain producer, the Sinograin (中粮集团) grain storage site is equipped with 4,500 high-definition cameras and 280,000 temperature sensors     7     (ensure) that the stock (储备) is in the best condition. Data shows that during China’s 13th Five-Year Plan period (2016-2020) , about 13 million tons of food had been saved     8     (year) after production.

We cannot end hunger     9     we do not deal with the high levels of food loss and waste. Cooperation and innovations (创新) in business models, technologies and digital solutions could all contribute     10     reducing food loss and waste.

4 . New methods have allowed researchers and scientists to find a way to reduce heat loss from buildings by about 30%. This new “green” solution is quite literally (确实地) green as it involves fitting a living wall by sticking soil and plants onto the walls, according to a new research.

To see what effects renewing a living wall on an existing building would have on the environment, the scientists decided to test it out on a building at a university in the UK, which was originally built in the 1970s. As a control, part of the building was not fitted with the living wall. Both of the parts of the building were west-facing and the test was conducted over 5 weeks. They found that the part with the living wall lost 31.4% less heat as compared to the side without it. So it took less energy to heat and had environmentally friendly effects.

In the UK, approximately 57% of buildings were built before 1964. They have caused 17% of greenhouse emissions (排放), about 60% of which come from house heating. If people could reduce heat loss from older buildings by 30%, a huge part of greenhouse emissions could be eliminated. While regulations have changed recently to improve the thermal performance (热性能) of new constructions, it is the existing buildings that require the most energy to heat and are a significant contributor to carbon emissions. It is, therefore, essential that people begin to improve the thermal performance of these existing buildings if the UK is to reach its target of net (净) zero carbon emission by 2050, and help to reduce the possibility of fuel poverty.

The new research suggests living walls can also provide significant energy savings to help reduce the carbon footprint of existing buildings. Perfecting these living wall systems, however, is now needed to help increase the environmental benefits.

1. What did the researchers find about the living wall in the test?

A．It protected the building very well.

B．It caused serious waste of some fuels.

C．It reduced the heat loss of the building.

D．It made the building look more beautiful.

2. What does the underlined word “eliminated” in paragraph 3 mean?

A．Repeated.

B．Removed.

C．Defeated.

D．Renewed.

3. What measure should the UK take to reduce carbon emission?

A．Pulling down the older buildings.

B．Cutting down the prices of fuels.

C．Reducing heat loss from the older buildings.

D．Adding more living walls to new buildings.

4. Which of the following can best describe the living wall?

A．Promising.

B．Doubtful.

C．Expensive.

D．Impracticable.

5 . Marie Van Brittan Brown, an African American nurse living in Jamaica, Queens in the 1960s, was working in shifts, as was her husband, Albert, an electronics technician. When she arrived home late, she sometimes felt afraid. Serious crimes in Queens jumped nearly 32 percent from 1960 to 1965, and police were slow to respond to emergency calls. Marie wanted to feel safer at home.

With the help of her husband, Marie imagined a device that could be attached to the front door. It would offer four small holes, and through these, a video camera on the inside could view visitors of different heights as the host turned the camera up and down. The camera was connected to a television monitor inside. A microphone on the outside of the door and a speaker inside allowed the host to interrogate a visitor, while an alarm could inform police via radio.

Closed-circuit television (CCTV), invented during World War II for military use, was not widespread in the 1960s, and the Browns proposed using the technology to create the first modern home security system. They filed a patent for their device in 1966, citing(提及) Marie as the lead inventor. It was approved three years later. “The equipment is not in production,” The New York Times reported, “but the Browns hope to interest manufacturers and home builders.” That never happened. “The cost of installing(安装) it widely would be pretty high,” says Robert McCrie, an emergency management expert at John Jay College of Criminal Justice in Manhattan.

Marie’s invention, though it didn’t benefit them financially, would earn the Browns a measure of recognition in the technology world: The predecessor(前身) of today’s home security systems, it has been cited(引用) in 35 U.S. patents.

4. What can we say about Marie and her husband?

A．They contributed a lot to CCTV.	B．They were generous and responsible.
C．They helped reduce crime in the 1960s.	D．They were intelligent and worthy of respect.

7 . Phillis Wheatley was born in Gambia (in Africa) on May 8, 1753 and died in Boston on December 5,1784. When she was seven or eight, she was sold as a slave to John and Susanna Wheatley of Boston. She was named after the ship that brought her to America, The Phillis. The family supposed the girl—who was “suffering from a change of climate”, with “no other covering than a dirty carpet”—to be “about seven years old...from the circumstances of shedding (使脱落) her front teeth”.

Phillis was very intelligent. The Wheatley family taught her to read and write, and encouraged her to write poetry. Her first poem On Messrs. Hussey and Coffin was published when she was only twelve. In 1770, An Elegiac Poem, on the Death of That Celebrated Divine, and Eminent Servant of Jesus Christ, the Reverend and Learned George Whitefield made her famous. It was published in Boston, Newport, and Philadelphia.

When she was eighteen, Phillis and Mrs Wheatley tried to sell a collection containing twenty-eight of Phillis’ poems. Colonists (殖民者) did not want to buy poetry written by an African. Mrs Wheatley wrote to England to ask Countess(女伯爵) of Huntingdon for help. The countess was a wealthy supporter of the abolition (废除) of slavery. Phillis had Poems on various subjects, religious and moral published in England in 1773. This book made Phillis famous in England and the thirteen colonies. She wrote a poem for George Washington in 1775, and he praised her work. They met in 1776. Phillis supported independence for the colonies during the Revolutionary War.

After her master died, Phillis was freed. She married John Peters, a free black man, in 1778. She and her husband lost two children. John was put into prison for debt in 1784. Phillis and her remaining child died in December of 1784 and were buried in an unmarked grave.

Phillis was the first African American and the first slave in the United States to publish a book. She was the first African American woman to earn a living from her writing. Phillis’ poetry proved the abolitionists’ idea that blacks could be artistic and intellectual. Her achievements were used to support a growing antislavery movement.

10 . On July 23, 2020, China successfully set off its first fully home-grown Mars mission, the Tianwen-1 on to a month- long space voyage toward the red Planet, marking a new era in a space exploration long controlled by NASA, USA.

Tianwen-1 consists of an orbiter (轨道器) and a lander. It’s the first attempt by any country to achieve orbiting, landing and roving all in one go. “If successful, it would mean a major technical breakthrough, ” scientists of the China National Space Agency (CNSA) wrote in a recent paper.

The orbiter, lander and rover probe (巡视器) combination lifted off from the Wenchang Satellite Launch Center on Hainan Island Thursday morning at 12: 41 a.m. American space and Mars enthusiast Elon Musk praised the mission on the website Thursday morning, calling the “launch” impressive.

In the Nature astronomy paper, CNSA researchers gave five scientific aims of the Tianwen-1 mission Map the geological structure of Mars, investigate surface soil characteristics, analyze surface material composition and study the Martian climate and environment at the surface, as well as the physical fields and internal structure of Mars. If all goes according to plan, the Tianwen-1 probe will reach Mars orbit in February next year. The orbiter will settle into a polar orbit that will allow it to observe the planets surface from a height between 165 miles and 7, 500 miles.

The Tianwen-1 mission is China’s second attempt at the Red Planet 2011 orbiter mission called Yinghuo-1 failed China is also the first country to land a probe on the far side of the moon. Last January, CNSA successfully sent a robotic lunar rover called Yutu-2 to the moon as part of the Change-4 mission. The rover is still roaming on the dark side of the moon studying the lunar composition.
