21、Craig Blackburn, a father and car fan, built a Batmobile for his son’s hope for using the vehicle to brighten the lives of sick children. And now he hopes to use it for more than just his son’s hope after seeing the children’s reaction to the Batmobile.
Based on the number of failures he had seen in car groups, he estimated that only about one in 50 attempted constructions was actually finished and he realized what an incredible opportunity he had.
Mr. Blackburn started the project at the beginning of 2018 after hearing a friend in the US was doing the same thing. It started with importing an outer shell overseas, before picking brains of a friend who had a background as a worker in a car factory to gain knowledge of how to build the car. With the help of his friend, Mr. Blackburn built the Batmobile in 18 months with the cost reaching six figures.
Mr. Blackburn hoped to add a flamethrower onto the back of the vehicle and said he had thought about building the more recent Batman Tumbler from the series film Dark Knight. Though Mr. Blackburn encountered plenty of difficulties to get over during the construction, in September 2019, the car made its first show at the Carnival of Flowers in Toowoomba, before being used by Blackburn’s son for his hope.
“It was great. It was so good to see the kids’ and adults’ excitement at seeing the Batmobile.” Mr. Blackburn said. As a result, the car lovers hope to make the car work on the roads as soon as possible, so he can visit sick children and take them out with his son.
【1】What is Craig Blackburn’s initial purpose of constructing the Batmobile?
A．To realise his son’s dream.
B．To donate it to sick children.
C．To pay his respects to the film Dark Knight.
D．To show off at the Carnival of Flowers in Toowoomba.
【2】How did Blackburn feel about the car-making?
A．Hopeful and interesting.
B．Unimaginable yet meaningful.
C．Impossible and boring.
D．Challenging yet worth-trying.
【3】How did Blackburn’s friend help him?
A．By making an outer shell for him.
B．By sharing the knowledge of building cars.
C．By offering him financial support.
D．By telling him the background of the car factory.
【4】What is the car lovers’ expectation of the Batmobile?
A．It will be put to practical use soon.
B．It can be displayed around the world.
C．It can change the lives of sick children.
D．It will appear in the next film about Batman.
22、Nobody wants to snack on plastic bags or soda rings, but according to a recent study from the University of Neweastle, we could be consuming roughly a credit card's worth of plastic every week.
Microplastic, which are less than a quarter-inch size and come in various shapes, have polluted the natural world and infiltrated(渗入)our bodies. The first clue to microplastic exposure in humans came around 2013, when scientists discovered plastic particles in seafood prepared for consumption. But in 2019, when the University of Newcastle study was published, the scientific community understood that the problem was considerably broader. Microplastics shed off clothes and tires and have been found in beer, honey, table salt and other food items. We breathe in plastic staying in the air and drink plastic floating in our drinks. It's no stretch to conclude that our exposure is significant. What we don't know is what this means for us.
The amount of evidence collected on this subject is growing rapidly, according to Scott Coffin, a toxicologist(毒理学家). Studies done on mice and rats have found that plastic in their bodies can severely damage cells and cause stress.
Because microplastics are too small to clean up, the only solution is to stop plastic waste at the source. And doing so would take a thorough adjustment, given that plastics are deeply embedded in our economy and lifestyle. Stopping using them would fundamentally affect countless industries, including textiles(纺织业), transportation and manufacturing.
"I think we need to have more studies coming out that are directly related to human health before we see a lot more concern from the general public," Scott said. "It takes a lot to convince people that something that is really convenient for them to use is something they should sacrifice."
The question of microplastics and human health needs more attention—from the scientific community ,the general public, the government and funding groups. The issue isn't being ignored, but it's not being prioritized either.
【1】What does the second paragraph mainly tell us about microplastics?
A．Their wide usage in daily life.
B．Their harm to human health.
C．Their significant exposure in humans.
D．The new study conducted on them.
【2】What does the underlined part "this subject" refer to?
A．The way that microplastics exist.
B．The pollution caused by microplastics.
C．The relationship between microplastics and human health.
D．The reason for the existence of microplastics.
【3】How to solve the problem according to Scott?
A．To cut down plastic production.
B．To carry out more studies on mice and rats.
C．To invent something more convenient than plastics.
D．To promote people's awareness on the harm brought by microplastics.
【4】Which of the following is a suitable title for the passage?
A．Is Microplastic pollution harmful to our health?
B．Why is Microplastic pollution everywhere?
C．Why is plastic harmful?
D．What do you know about Microplastics?
23、 Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.
For species(物种)like chimpanzees, which have complex social lives and live for many years，getting photos of their behavior taken from short-term field research can only tell us so much，” says Dan Schofield， researcher and DPhil student at Oxford University’s Private Models Lab, School of Anthropology. “By taking advantage of the power of machine learning to unlock large video files , it makes it possible to measure behavior over the long term. ’’
The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea,West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality.
“Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible,” says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science ,University of Oxford .” Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预)，saving hours of time. ”
The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.
【1】What is the purpose of developing the new soft?
A.To save wildlife researchers’ time spent in the labs.
B.To keep track of wildlife conservationists' behaviors.
C.To protect chimpanzees and help them to live longer .
D.To recognize and track the faces of wild chimpanzees.
【2】What does the underlined word “it” in paragraph 2 refer to?
A.Getting photos. B.Analyzing videos.
C.A powerful machine D.The new AI software.
【3】What does paragraph 4 mainly talk about?
A.The working principle of the new software. B.Some limitations of using the new software.
C.The unique advantages of the new software. D.Controversial attitudes to the new software.
【4】What can be known from the last paragraph?
A.Technology advance is the final goal of science
B.The new software won’t just be applied to chimpanzees.
C.AI systems are widely used in the wildlife sciences.
D.The application of the new technology isn’t easy.
24、阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Last Sunday I made a visit to some new neighbors down the block．No specific in mind, just an opportunity to sit at the kitchen table, have some tea and chat．As I did so, it occurred to me how rare the Sunday visit has become．
When I was a kid in New Jersey of the 1960s, Sunday visits were routine．Most stores were closed, almost nobody worked, and the highways, as a result, were not desperate steeplechases（障碍赛跑）they have become today．My family normally traveled eight city blocks to the home of my grandmother, where adults would sit on the front porch and chat while we children played hide-and-seek．
The Sunday visit was something to desire strongly．It was the repetition to church, our reward for an hour of devotion, an opportunity to take advantage of the fact that Dad was not at work, we were not in school, and there was no housework that couldn’t wait until Monday．Sunday was, indeed, different from the other days of the week, because everyone seemed to be on the same schedule, which means that there was one day when everyone seemed to have time for everybody else．
Sunday as a day of rest is, or was, so deeply rooted in the culture that it’s surprising to find that, in a short span of time, it has almost entirely lost this association．In my childhood, it was assumed that everyone would either be home or visiting someone else’s home on Sunday．But now the question is, “What do you plan to DO this Sunday?” The answer can range from going to the mall, to participating in a road race, to Montreal for lunch．If one were to respond, “I’m making a Sunday visit to family,” such an answer would feel strange, which sounds like an echo from another era．
I suppose I should be grateful to live in Maine, a state of small towns, abundant land and tight relationships．Even though folks work as hard here as they do anywhere else, the state’s powerfully rural feature still keeps at least remnants（残余部分）of the moral of yesterday’s America, where people had to depend on one another in the face of economic vagaries（反复无常的情况）and a challenging environment．
【1】The writer’s general impression of the Sunday in the past was a day when＿＿．
A．everyone was paying a visit to some relatives far away
B．everyone seemed to be free for others
C．Dad was not at work while Mom was busy cleaning the house
D．nearly every adult would go to church and children weren’t at school
【2】In the fourth paragraph, the writer compares the response “I’m making a Sunday visit to family” to an echo from another era because_____．
A．people nowadays prefer staying at home on Sunday
B．such answers are rarely heard in our modern society
C．people in the city dislike being disturbed on Sunday
D．visiting someone on Sunday was routine in the past
【3】From the last paragraph we may infer that_____．
A．people in Maine suffer more from economic depression and the changed environment
B．people in Maine have abandoned their tradition and lived an absolutely new life
C．land in Maine is short, thus the relationship between people is tense
D．people in Maine tend to help each other out of necessity
【4】What’s the main idea of the passage?
A．Doing many activities on Sunday is beneficial．
B．We should often travel a long distance to visit some friends and relatives．
C．Nowadays, Sunday has almost lost its association as a day of rest．
D．We should abandon some old tradition．
25、My name is Maggie and I am a big red maple tree in the center of Central Park in New York. Every part of me is_______shaped. I love seeing all the people_______, stare at me, and say “That tree is beautiful!” Those_______make me feel special.

Hours later, when the storm_______, a nice opossum (负鼠) family comes to me and asks_______they can spend the night in one of my holes. The baby opossum is so cute that I can’t_______. Soon, round two of the storm comes. It________another part of my bark, but it doesn’t________me as much because I have a distraction (分散注意力的事物): the opossum family. Other animals see my________act and come to me, too. Even though I feel great for________all the animals, I still haven’t completely forgotten about what people might think about my________. Beyond all expectations, people love me even more for sheltering all those animals from the terrible storm. I will forever________that “beautiful” doesn’t always refer to looks.
