21、 China has passed its peak of the COVID-19 outbreak, with new cases trickling down to single digits and overall epidemic（流行病）situation improving. The order of life and production is being restored at an increasing pace.
However, it gets worse abroad. The number of confirmed coronavirus cases in the U.S surged to 13,350 on Sunday and 188 Americans have died. The economy is taking a hit, such as the New York Stock Exchange and airline business. "We started seeing very sharp declines," Gary Kelly, the CEO of Southwest Airlines, said on CNBC weeks ago, "It has a 9/11-like feel."
In China, to contain the spread of the novel coronavirus. China has launched a people's war against the epidemic, adopting the strictest and most thorough measures. Foreign countries are also joining in China's efforts to combat the epidemic.
Whereas, the USA president Trump previously said at the start of a business roundtable in New Delhi, "a problem that's going to go away." He also heaped praise on Chinese President Xi Jinping in dealing with the pneumonia（肺炎）-like disease. Director of Harvard Global Health Institute Ashish Jha warned that the epidemic is the most possible cause that can accidentally kill millions of Americans, but also the one that sees the least preparation.
Chinese Ambassador to the United Kingdom Liu Xiaoming said that since the outbreak of the coronavirus, China has donated masks and supplies, for example to Iran and Italy, Japan and South Korea. It has engaged in global cooperation and shared information in a timely manner with the world, including the USA, on the genetic sequence of the virus and on vaccine development. United Nations Secretary- General Antonio Guterres on Monday praised China's contribution, noting that Chinese people are making efforts for all of humanity. Liu said, "We have been open, transparent and responsible in tackling the virus because we believe in a community with a shared future for mankind."

22、YOU may like chewing gum (口香糖) after meals to stop your breath smelling bad; or your mother might use a special neutralizer (调理剂) to protect her permed hair (烫发). But have you thought about the chemical principles behind such everyday actions?
On March 2, the Senior 3 students from the IB (International Baccalaureate, 国际文凭) classes at Beijing Huijia Private School presented their discoveries, all in fluent English. This kind of seminar is held every year to show the achievements of the IB chemistry experiment lessons offered by the school. IB is a qualification based on a common curriculum (课程) for students aged 16-18 in any country and is recognized by universities everywhere.
"Once I saw an advertisement for xylitol (木糖醇) gum," recalled Zhang Xinju. "Suddenly an idea came to my mind: are there any chemical reactions when the xylitol is working on our teeth?"
Zhang and his partner Bu Xuan visited several hospitals to try and find out. "Doctors know that xylitol can protect teeth, but few could explain how the chemical reactions happen," said the 17-year-old boy.
Presenting the results of their research in English to an audience of Chinese and foreign judges was never a problem for the students.
"Textbooks for IB students are in English, and our teachers speak in English," explained Wei Duan and Han Yu, whose research topic was "The Acid-Base Reaction (酸碱反应) in the process of Hair-Perming".
"In Senior 1 we often referred to Chinese textbooks, but we found we could understand and express it all in English by the second year."
Lu Jiang, the school's IB chemistry teacher and China's only IB vice-examiner, is proud that her students can apply scientific theories they learn in class to daily life.
"You might have learned these facts from you kindergarten teachers, but few think about the theories behind them," Lu said. "This kind of practice is intended to develop the scientific thinking they will need in their future studies."
【1】IB is recognized by____________.

23、Recently, a new discovery has been made in the field of biology that challenges our previous understanding of the origins of life on Earth. For decades, scientists believed that life emerged in a warm, shallow pond, where a series of chemical reactions led to the creation of the first living cells. However, a team of researchers has now uncovered evidence that suggests life may have actually begun in a quite different environment.
The discovery was made in a remote part of the ocean, where a team of scientists was exploring a hydrothermal vent (深海热泉) system located deep beneath the surface. Hydrothermal vents release superheated water and gases from the Earth’s mantle (地幔). They create an extreme environment that is unfavourable to most forms of life, but home to a variety of unique organisms.
As the scientists collected samples of the vent’s mineral-rich liquid, they noticed something strange. They discovered that it contained a complex network of organic molecules (分子), including amino acids (氨基酸) and other building blocks of life. This was surprising, as hydrothermal vents were previously thought to be empty of life-supporting chemicals. However, the most striking discovery was yet to come. Analysis of the organic molecules revealed that they were not simply the product of chemical reactions in the vent, but rather had been produced by living organisms. This served as evidence of a lively ecosystem that was completely independent of sunlight and the surface world.
This discovery has significant implications for our understanding of the origins of life on Earth. The warm pond hypothesis (假说), which has long been the dominant theory, suggests that life emerged in a relatively warm and damp environment. However, the new evidence from the hydrothermal vent system suggests that life may have actually begun in an extreme environment, where survival was only possible through the development of original biochemical pathways. The discovery also raises new questions about the potential for life to exist on other celestial bodies (天体). Hydrothermal vents have been identified on Saturn’s moon Enceladus and Jupiter’s moon Europa. The presence of organic molecules at these sites suggests that unique forms of life may exist.
While this discovery is still in its early stages, it is already beginning to reshape our understanding of the origins of life and the potential for life on other planets. It is a testament to the power of scientific exploration and the incredible complexity of life on Earth. As we continue to explore the depths of the ocean and the vast expanse of space, who knows what other surprises and discoveries lie in store.
【1】What did the scientists newly discover in the vent’s liquid?
A．Superheated gases.
B．A variety of minerals.
C．Life-supporting chemicals.
D．Complex forms of life.
【2】What can we learn from the passage?

B．Scientists have addressed the limitations of the research.
C．New discoveries inspire us to further explore the unknown.
D．Researchers have confirmed the origins and complexity of life.
24、 As we all know, most animals only perform tricks when given treats. However, Kim, the world’s first spider to learn a skill, needs no stimulus (刺激物) to do what she loves—jumping from different heights and distances— upon the instruction of a team of scientists from the University of Manchester.
While the idea of training a spider might sound evil, the researchers’ motives were purely scientific. They are trying to unlock the secrets behind the jumping spiders’ extraordinarily high leaps to catch prey (猎物) or to escape their enemies. A better understanding of the spiders’ leaps would help experts develop more efficient flying and jumping robots.
The scientists found that Kim could gather enough force in her legs to jump more than six times the length of her own body from a stationary position. What was even more amazing was that she always landed perfectly. For shorter distances, Kim used a lot of energy, resulting in quick leaps, which the researchers believe probably increases her chances of catching fast-moving prey. The farther the distance, the less extra energy was used, resulting in slower but precise leaps.
Previous studies have indicated that spiders use both their muscles and hydraulic (液压的) pressure—a mechanism by which blood is transferred to their extended legs—to push them off the ground. However, in Kim’s case, her leg muscles alone appeared to be generating enough force for the liftoff. The researchers now intend to do further research to comprehend fully not just the spiders’ jumping technique, but that of other insects as well. “We are familiar with robots that are aimed at taking over human functions, but there are millions of insects in the world that perform specific functions that we have interest in adapting to robotics,” says Nabawy, the leading engineer of the researching team.
【1】What is the purpose of scientists’ researching the jumping spider?
A.To have fun and relax. B.To help develop robots.
C.To get rid of spiders. D.To protect this species.
【2】Why did Kim use a lot of energy for short leaps?
A.To jump high enough.
B.To land more precisely.

D.To increase chances of escape.
【3】What does the underlined word “that” in the last paragraph refers to?
A.Jumping technique. B.Leg muscle.
C.Further research. D.Energy for liftoff.
【4】What can be a suitable title of this passage?
A.Jumping Techniques Used by Jumping Spider
B.Jumping Spider Inspired Creating Robots
C.Animals Perform Tricks if Provided with Treats
D.The World’s First Spider That Jumps on Demand
