医生首次将“ 猪心脏” 移植给人类 On January 12, 2022, doctors at the University of Maryland Medical Center were very thrilled（激动的）.They finished replacing the heart of a very sick man with a specially-grown pig"s heart. It"s the first time that this surgery has ever been done. After three days, the patient appeared to be doing very well. “It"s working and it looks normal,” said Dr Bartley Griffith，the surgeon（外科医生）
who performed the operation. “We don"t know what tomorrow will bring us. This has never been done before.” David Bennett, who"s 57, is the man who was given the new heart. He was given special permission（许可）to have the unusual operation because without it, he would have died. “Either die or do this transplant,” said Mr Bennett.“I want to live.” For years, scientists have tried to figure out how to transplant organs from other animals into humans. This is hard because the human body almost always rejects (doesn"t accept) something that isn"t its own. This even includes some transplants from humans. Scientists have tried transplanting organs from a chimpanzee（黑猩猩）or a baboon, a large African or Arabian monkey with a dog. like face, but this didn"t work very well.*
More recently, scientists have focused on transplants from pigs, Pig organs contain a special chemical that causes human bodies to reject them. This time, to prevent that, scientists changed the pig"s DNA so it wouldn"t produce the chemical. Scientists made several other changes to the pig"s DNA, and even added some things normally found in human DNA. It"s good news that Mr Bennett"s body has shown no signs of rejecting the heart. For Mr Bennett, the new surgery is a life-saver. 1 Which of the following is NOT true about David Bennett? A. He is a 57-year-old patient with a heart problem. B. He didn"t agree to have a heart operation. C. He is the first man to have a pig"s heart. D. His operation was performed by Dr Bartley Griffith. 2 The underlined word “it” in Paragraph 3 refers to
. A. the special permission B. a specially-grown pig"s heart C. a surgery to repair his heart valves（瓣膜）
D. the unusual transplant operation 3 Paragraph 4 mainly tells us
. A. scientists focused on heart transplants all the time B. it is difficult to transplant animal organs into humans C. scientists have tried transplanting organs from lots of animals D. a baboon is a large monkey with a dog-like face 4 Which word can best describe Mr Bennett"s operation? A. Successful. B. Dangerous. C. Painful. D. Common

南太平洋岛国汤加海底火山喷发 Tonga is an island nation in the South Pacific Ocean. On January 14,2022,an underwater volcano erupted （喷发）near Tonga.
The volcano is located off the coast of Tonga. It first began to erupt on Friday. Even though the volcano was underwater, it sent a column of gas, ash, and stones 20 kilometers into the sky. Saturday"s eruption was far larger. It"s believed to be the largest in over 20 years. The eruption caused a loud “sonic boom（音爆）”，which could be heard even in Alaska, 10,000 kilometers away. The eruption caused a 5.8 magnitude earthquake， as well as tsunami （海啸）waves that traveled far and wide. In Japan, Chile and Australia, people moved away from low-lying areas along the coast. The waves sunk boats in New Zealand and caused two deaths in Peru. The event knocked out Internet services in the area. Like most island nations, Tonga gets its Internet through a cable that runs deep under the sea. The reports of injuries and deaths in Tonga related to the eruption couldn"t be known in time because of problems with communication.* In the following days, the smoke and ash from the volcano covered much of Tonga, The ash made the air dangerous to breathe and polluted many sources of drinking water, That was the biggest danger which might last for a long time. New Zealand and Australia sent learns to Tonga to help out. Some of the teams used airplanes to get a better idea of the damage across the island nation. But at that time, the large cloud of ash high above Tonga was making it impossible to get a good picture of what was happening in the area from high in the air. The United States and the World Health Organization also sent help to Tonga. 1 Which is the right order of the following events? a. People in Alaska heard a loud “sonic boom”. b. Tsunami waves caused two deaths in Peru. c. The largest eruption of the volcano happened. d. The volcano began to erupt on January 14. A. c-d-a-b B. d-a-c-d C. d-c-a-b D. a-d-b-c 2 The biggest danger the volcano caused comes from__________. A. a 5.8 magnitude earthquake B. the tsunami waves C. the smoke and ash from the volcano D. the problems with communication 3 What"s the main idea of the last paragraph?
A. New Zealand and Australia helped Tonga out. B. Airplanes could help know the damage across the island nation. C. People couldn"t make sure what was happening in Tonga at that time. D. Tonga got help from other countries and the WHO. 4 What is the best title for the passage? A. An island nation in the South Pacific Ocean B. Tsunamis and flooding from California to Alaska C. An underwater volcano erupted near Tonga D. The eruption of a volcano caused many deaths
C 阅读理解 主题：的 科学家通过采集空气中的 DNA 鉴别动物 Scientists have come up with a new way of identifying animals in an area-by testing DNA in the air. Two teams of scientists-one in Denmark and one in the United Kingdom-came up with the same question at about the same time: Could they identify the animals in an area from DNA that was simply floating in the air? DNA and eDNA Every living thing has DNA that can be used to identify it. They leave bits of DNA behind them wherever they go. DNA left behind like this is called “environmental” DNA, or eDNA. Scientists can use it to tell what kinds of animals are in a certain place. Testing for eDNA isn"t a new idea, but most of the time, scientists look for eDNA in water. Neither team knew that the other group was working on a similar experiment. One collected samples from different locations at Denmark"s Copenhagen Zoo, and the other at Hamerton Zoo Park in the UK. The scientists used slightly different methods to collect their samples. But basically， both teams used vacuums （真空吸尘器）
and fans to collect tiny bits of DNA. In the laboratory, by comparing their samples with examples of DNA from different animals, the scientists were able to identify many different animals at the zoos. The scientists chose to test in zoos because they had rare animals not naturally found in the area.* Each team
only discovered about the other experiment after they had written a paper about their own results. The two decided to combine（合并）their results and publish a paper together. Both teams are excited about the ways this new method could be used in the wild. The researchers believe the method could help scientists a lot. Scientists have been looking for better ways to track endangered animals without interfering （干扰）with them. If researchers know where the animals live, they can do a better job of protecting them. The next step is to figure out how to take this method into nature.
1 What can we learn about “eDNA” from the passage? A. It only floats in the air. B. It"s created by some researchers. C. It can"t be found in water. D. It"s left in the environment. 2 Which of the following is TRUE about the two teams of scientists? A. They used quite different methods. B. They knew exactly what each other was doing at first. C. They competed against each other. D. They worked together to publish a paper. 3 What"s the purpose of the last paragraph? A. To advise scientists to use new ways to do the experiment. B. To tell us the work of both teams is meaningful. C. To mention that the method of both teams isn"t perfect. D. To call people to protect endangered animals. 4 What is the best title for the passage? A. Two teams of scientists find rare animals B. Differences between DNA and eDNA C. Scientists identify animals by DNA in the air D. How to track endangered animals

昆明至万象“ 中老铁路” 正式通车！
On December 3,2021,the China-Laos Railway started operation. After five years of construction （建设）， the new high-speed railway was finally opened on Friday. Laos＇ President Thongloun Sisoulith and Chinese President Xi Jinping spoke over a video connection at the opening ceremony. The railway runs 1,035 kilometers, including 422 kilometers in Laos, from the city of Kunming to Vientiane （万象），the capital of Laos． The trains can travel at a speed of 160 km per hour， through mountains and valleys． It can slash （大幅度 削减）
the travel time between the two cities to about 10 hours. The China-Laos Railway is a flagship project of mutually （互相地）
beneficial cooperation between the two countries. The project is a huge step forward for Laos, which only had 4 kilometers of rail lines before this. Laos is the only country in southeast Asia with no connection to the sea. Being able to send products quickly to and from China will make it much easier for Laos to do business with other countries. It will also make it far easier for Chinese tourists to visit. Construction of the Laos section started in December 2016,and construction of the China part linking Yuxi and the border town of Mohan started in December 2015.A total of 167 tunnels and 301 bridges were built along the new sections, after builders overcame many technical difficulties. The China-Laos Railway is a landmark project of high-quality Belt and Road cooperation. In recent years, China has continuously improved the level of Belt and Road cooperation, achieved mutual benefits and win-win results for participating countries, and opened up new space for the development of the world economy. 阅读短文，根据短文内容简要回答下列问题。
