63．句意：它是由联合国发起的，目的是让人们更多地了解自闭症，并为自闭症患者提供更好的照顾和支持。句子是定语从句，先行词those表示人，因此用who引导定语从句，故填(w)ho。

七、材料作文
71．例文：
Artificial Intelligence (AI) has played an important part in people’s everyday life since it was put forward in 1956. It is estimated that the artificial intelligence in the field of education will grow by 50% from 2017 to 2021 in the United States. Peter’s opinion is that AI can solve all problems. And in the future, we don’t need teachers anymore. Students can learn better with the help of AI.
But in my opinion, AI is not good at moral education, so we also need many teachers. With the development of AI, the teachers and AI should work together in order to promote students’ progress. In a word, I think the important existence of teachers is irreplaceable and there will be many changes in the practices of teachers’ work.

三、阅读单选（本大题共15小题，每小题1分，共15分）
（A）
Plants need to eat just like animals do. However, unlike animals, plants cannot move around to find food. Instead, they have developed special ways to get “food” from things around them.
One of the main ways of plants eating is through photosynthesis (光合作用). This process involves using sunlight, water and CO2 to create glucose (葡萄糖) which is a type of sugar that plants use for energy. Chlorophyll (叶绿素) is responsible for catching sunlight and turning it into energy. Trees are some of the largest and longest-lived photosynthetic plants on Earth. They play an important role in controlling the Earth’s climate by taking in CO2 from the air and giving off O2.
Another way for plants to eat is through their roots. Roots take in water and other things from the soil, which are then sent to the rest of the plant. This process is important for the growth and development of plants, as it provides them with the nutrients (营养)they need to survive (生存). For example, some plants are able to live in arid environments. Their roots are used to take in water from the soil, and they have thick leaves to store water.
Carnivorous (食肉的) plants are a fascinating example of how plants get their food. Some plants eat insects and other small animals. These plants have special leaves that catch their food. For example, the pitcher plant (猪笼草)is a kind of carnivorous plant. Its leaves are in a special shape, with a smooth surface that makes it difficult for insects to climb out once they have fallen in.
( )31．How do plants eat according to Paragraph 2
A．By taking in soil. B．Through their roots.
C．By catching animals. D．Through photosynthesis.
( )32．What is the role of chlorophyll in photosynthesis
A．Taking in CO2 from the air and giving off O2.
B．Catching sunlight and turning it into energy.
C．Sending water from the soil to the rest of a plant.
D．Catching and eating insects and other small animals.
( )33．What does the underlined word “arid” mean in the third paragraph
A．Wild. B．Cold. C．Dry. D．Terrible.
( )34．Which paragraph tells us how carnivorous plants get their food
A．① B．② C．③ D．④
( )35．What is the best title for the text
A．How Plants Get Their Food B．How Plants Influence Climate

Chinese AI Model DeepSeek-R1 Stuns the World January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, write code, and answer questions like top models such as OpenAI’s GPT-40, but it costs much less to build. The team spent only $5.58 million (1/70 of OpenAI’s cost) and used 2,048 computer chips for two months. This shows that good ideas can beat big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, slightly higher than OpenAI’s model. A simple version of R1 can even run on low-cost computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers worldwide started projects to study it. A German scientist said experiments with R1 cost $10 instead of $300 with other AIs. Even Meta (a famous U.S. tech company) top scientist said, “This kind of free AI could change the world.”
U.S. tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving that smart ideas beat expensive tools. As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money.

Do you know some people can “see” the world by using their ears
People need to make clicking sounds with their tongues. When the sound waves hit an object, they come back as echoes (回声). Then people listen to the differences in the echoes and tell where the thing is in the dark so they can find their way. This is called echolocation. By practicing this, blind people now can do many things, including riding bikes alone or playing basketball! All these used to be impossible for them without this skill.
In the past, scientists thought only blind people could learn echolocation. According to a research, after a person loses his sight (视力), there are some changes in his brain. So his brain works differently compared with the past. Scientists believed this was the key to leaning echolocation. But now a new study shows that sighted people can learn it too! In the study, both blind and sighted people were trained for 10 weeks, learning to make clicking sounds and use them to navigate in the dark. With practice, both groups improved! They could find their position and direction to go.
What’s the reason behind When scientists studied their brains after the 10-week training, they found that the visual cortex (视觉皮层) became more active when people listened. This happened to both blind and sighted people! Scientists guess this part of brain doesn’t just control what people see—it also deals with information from other senses, like hearing, smell and taste.
For blind people, echolocation is more than a skill that makes their lives easier. Many said they felt more confident. Even more, this discovery shows how powerful human’s brains are. Even if you can’t see, your brain can learn new skills, using sounds to help you “see” the world!

Have you ever h 61 of the term “children of the stars” It’s a special name for children with autism (自闭症). April 2 is World Autism Awareness Day. It was started by the United Nations to make people know m 62 about autism and offer better care and support to those w 63 have it.
Autism affects (影响) how a person grows and learns. It usually starts to show within the f 64 three years of life. The official (官方的) name for this condition is “autism spectrum disorder (自闭症谱系障碍).” Doctors use a handbook 4 DSM-5 to diagnose (诊断) autism. It talks about two main autism signs: problems with talking and helping with o 65 and doing the same things over and over again.
“When I talk to my daughter or ask her to do something, she won’t pay a 66 to me,” said Meng Lingdi. Her daughter was diagnosed with autism at 2 years old. “She doesn’t make as much eye contact (接触) with people a 67 another kids do.” Children with autism also feel physical pain. “Many of them have epilepsy (癫痫) because their brain activity is d 68 from that of other kids,” said Sun Zhongkai at Beijing Stars and Rain Education Institute for Autism (Stars and Rain).
We don’t know e 69 what causes autism. But scientists think it might be a mix of things like how we grow, our genes (基因), and our environment. If a family has a child with autism, the chance of their other children having autism is about 10 times higher than u 70 .
