Soon the news of friendly dolphins swimming around Monkey Mia began to spread, and before long the beach became very popular. However, by the 1980s, researchers had noticed a worrying fact —as adult dolphins became more dependent on humans for food, more and more of their babies died. Things got so bad that 90% of the babies failed to grow up. Luckily, the local government started to control dolphin feeding.Today, only a small number of dolphins visit the Monkey Mia beach every day. And they are only fed a little fish so that they still go out hunting(猎食) and teach their young survival(生存) skills. Visitors can only feed the dolphins when they are allowed. “We only feed them around 10% of their daily food,” said Luke Skinner, a staff member there. “This makes them go and hunt for 90% of their food.”The dolphins that visit Monkey Mia every morning draw more than 100,000 visitors to the beach each year. Visitors can get close to the dolphins, play with them and learn about them and their habitat.36．What do we know about Monkey Mia?A．It is a zoo. B．It is a beach in Australia.C．It is named after a fisherman. D．It is a natural habitat of monkeys.37．What does the underlined word “them” in Paragraph 2 refer to (指的是) ?A．The dolphins. B．The fishermen. C．The monkeys. D．The researchers.38．What happened in the 1980s?A．Lots of adult dolphins began to die.B．Many dolphins were killed by fishermen.C．Monkey Mia became too crowded with visitors.D．More and more baby dolphins failed to grow up.39．How does the local government protect the dolphins?A．By protecting their habitat. B．By controlling dolphin feeding.C．By teaching them hunting skills. D．By cutting down the number of visitors.40．The writer wrote the passage to ________.A．introduce the best place the dolphins live inB．advise us to teach baby animals survival skillsC．show the reasons why the visitors can’t feed the dolphinsD．tell us to pay more attention to animals, survival rulesDBy Global TimesMay 12th, 2022______▲______China’s Zhurong rover (祝融号) has found evidence (证据) showing that water has been on Mars (火星) much longer than expected.Zhurong, named after the Chinese god of fire, landed safely on Mars on May 15th, 2021, making China only the second behind the United States to fully succeed.Zhurong, the Mars rover, is 1.85 meters high and weighs about 240 kilograms. It has six wheels and four solar panels (太阳能面板) and it can move at 200 meters an hour on Mars.The rover’s three-month primary mission (任务) was to search for signs of ancient life.

The rover returned some information from its primary survey of the basin. It shows that Utopia Planitia basin had water during a time, but many scientists used to believe Mars to be dry and cold.“Mars is the planet we are most likely to live on in the future. That’s why we want to understand it,” said Ge, a scientist in China’s space program. “Zhurong’s evidence of water on Mars makes great progress in future Mars missions!”41．China becomes only the ________ to land a rover successfully on Mars according to the passage.A．first B．second C．third D．fourth42．Which picture does Zhurong rover look like?A．B．C．D．43．According to the passage, we can infer (推断) that ________.A．the news came out on May 15th, 2021 B．the rover returned three months agoC．the rover may send pictures back to the Tianwen-1 D．Mars used to be dry and cold in the ancient time 44．What does the underlined word “it” refer to (指代) in the last paragraph?A．Tianwen-1.

My friend was waiting for me when my plane landed at Kennedy Airport at three o’clock in the afternoon. The weather was very co ld and it was snowing, but I was too excited to mind. From the airport, my friend and I took a taxi to my hotel. On the way, I saw the skyline of Manhattan for the first time and I stared in astonishment at the famous skyscrapers（高楼大厦）and their man-made beauty. My friend helped me unpack at the hotel and then left me because he had to go back to work. He promised to return the next day.Shortly after my friend had left, I went to a restaurant near the hotel to get something to eat. Because I couldn’t speak a word of English, I couldn’t tell the waiter what I wanted. I was very upset and started to make some gestures, but the waiter didn’t understand me. Finally, I ordered the same thing the man at the next table was eating. After dinner, I started to walk along Broadway until I came to Times Square with its movie theatres, neon lights, and huge crowds of people. I did not feel tired, so I continued to walk around the city. I wanted to see everything on my first day. I knew it was impossible, but I wanted to try.When I returned to the hotel, I was exhausted, but I couldn’t sleep because I kept hearing the fire and police sirens during the night. I lay awake and thought about New York. It was a very big and interesting city with many tall buildings and big cars, and full of noise and busy people. I also decided right then that I had to learn to speak English.1. On the way to his hotel, the writer __B_____.A. was silent all the timeB. looked out of the window with great interestC. kept talking to his friendD. showed his friend something he brought with him2.

That night he could not sleep, because __D_______.A. he did not know what to do the next dayB. he was not tired at allC. he was thinking about this great cityD. he kept hearing the fire and police sirens答案：1-5BDACDPassage 2Some people think they have an answer to the troubles of automobile crowding and dirty air in large cities．Their answer is the bicycle，or “bike”．In a great many cities，hundreds of people ride bicycles to work every day．In New York City，some bikers have even formed a group called Bike for a Better City．They claim that if more people rode bicycles to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air from car engines.For several years this group has been trying to get the city government to help bike riders．For example，they want the city to draw bicycle lanes on some of the main streets, because when bike riders have to use the same lanes as cars, there are accidents．Bike for a Better City feels that if there were special lanes more people would use bikes．But no bicycle lanes have been drawn．Not everyone thinks it is a good idea—they say it will slow traffic．Some store owners on the main streets say that if there is less traffic，they will have less business. And most people live too far from downtown to travel by bike．The city government has not yet decided what to do．It wants to keep everyone happy．Only on weekends, Central Park is closed to cars，and the roads may be used by bicycles only．But Bike for a Better City says this is not enough and keeps fighting to get bicycle lanes downtown．6．According to the passage，bicycles___D_____.A．are more convenient than cars B．are safer traffic tools than cars C．are ridden by most people in the U．S．D．are the solution to some city problems 7．The idea of special bicycle lanes is most favored by___B______.A．the city government B．some bike ridersC．people living far from downtown D．some store owners8．“Bicycle lanes” in the third paragraph probably means __C____.A. narrow passages between buildings for bicycles B．roads full of bicyclesC. special parts of the road for bicycle riders only D．roads for bicycles only 9．Which of the following is not true according to the passage? D A．Bike for a Better City members ride bicycles to work．B．Sometimes accidents may occur when cars and bikes are on the same lanes．C．The Central Park is closed to cars on weekends．D．In New York City．many people use bikes as they have special lanes．10．The best title for this passage is ___D______.A．Traffic Crowding in New York City B．Air Pollution in New York City by Cars C．Special Lanes for Passengers D．A Solution to Traffic Problem in New York 答案：6-10 DBCDDPassage 3Online learning is also called distance education. Many American colleges and universities have been offering（提供）it for years.One example is New York University in Manhattan. The School of Continuing and Professional Studies began online classes in nineteen ninety-two. Its Virtual （虚拟的）College has taught more than ten thousand students from across the United States and other countries.Last year, the School of Continuing and Professional Studies launched NYU Online. It offers NYU's first online programs to earn a bachelor's degree. Programs are offered in three areas: leadership and management, information systems management and social sciences. University officials say classes are highly interactive,（交互性）where students communicate with each other and their teachers. Some classes require students to all log in at the same time so they can attend live lectures by a professor. Students can also ask questions and work together on team projects. The university says classes are taught by NYU professors who have been trained in online teaching. International students must take two admissions tests before they can be accepted into the program. These are the SAT （Scholastic Assessment Test）and the TOEFL.We will discuss these tests later in our series.The cost to attend NYU Online depends on how many classes a student takes. It can cost as much as fifteen thousand dollars a year. NYU offers no financial aid （奖学金补助）for international students in this program. You can get more details at .11.When did New York University start its online classes？BA. In 1990B. In 1992C. In 1998D.
