21、India has the world's worst air pollution. Home to 21 of the world's 30 most polluted cities, its poisonous air kills more than one million people each year.
Being the world's second largest brick producer, India's brick kilns (砖窋) account for 
of black carbon emissions globally. Architect Tejas Sidnal was astonished to discover the construction industry's role in the pollution crisis. "That was a crazy eye opener," he says. "As architects, we are responsible for so much air pollution."
Determined to make construction more sustainable and tackle India's air pollution, Sidnal launched Carbon Craft Design in 2019. The startup takes black carbon extracted from polluted air and upcycles it to make stylish, handcrafted building tiles (瓷砖).
To create the carbon tiles, Carbon Craft Design, together with Graviky Labs, uses a filter device to capture carbon soot (碳黑) from tail gas and fossil fuel generators, removes pollutants such as heavy metals and dust from the soot, and gives the purified carbon to Carbon Craft Design in powder form. The company then mixes the captured carbon with cement and marble waste from quarries to produce monochromatic tiles. The company aims to ensure each tile contains at least 
waste material. It sells the tiles to architects and retailers (零售商) for 
per square meter-a high price compared to regular tiles.
As the company expands production, Sidnal hopes to lower prices and produce a cheaper range of carbon tiles. "We want to hit the affordable sector," he says. "Sustainability is not only for the elite (精英)."
Since launching its first tiles a year ago, Carbon Craft Design's customers have included global fashion brands and architecture firms in India. In November 2020, an Adidas store in Mumbai covered the walls and the floor with its carbon tiles. Inquiries from in and out of India came flooding in.
Architect Manan Gala describes the carbon tile as a "winner", which, apart from being sustainable, has better strength than conventional cement tiles due to the carbon content, and the raw and rustic feel adds to the overall charm.
【1】What does the underlined part in paragraph 2 mean?
A．Something shocking.
B．Something impossible.
C．Something ridiculous.
D．Something unavoidable.
【2】What can we learn from paragraph 4 ?
A．The price of each tile.
B．The way to produce the carbon tiles.
C．The purpose of purifying the air.
D．The reason for producing the carbon tiles.
【3】Carbon tiles have advantages in the following aspects except in ________.
A．strength
B．sustainability
C．appearance
D．price
22、Chinese food is considered to be the biggest cultural exchange between China and other countries. The following dishes are each special in their own way.
Peking Duck
This famous dish can be found at restaurants all around Beijing. High class restaurants take this dish so seriously that some even have their own duck farms and use only a special kind of duck for their specific Peking Duck dish. Peking Duck is famous for its, thin skin, and its delicious meat, which is highly popular among all foreigners, including foreign celebrities and leaders.
Won Ton Soup
Won Ton Soup, called "Hun Dun" in Chinese, is a highly welcoming dish in China. Since China is a country of many nationalities and different cultures, each region has their own shapes for won tons. Won tons are usually boiled and served in soup, but they can also be deep- fried.
Dumplings
During the Spring Festival, Chinese families will get together and have dumpling parties. It is said that the dish was invented by Zhang Zhongjing, one of the finest Chinese physicians in history. Dumplings have a 1,800-year-long history, which is why it is one of the most popular traditional foods in China and extremely popular in Western countries. They may be cooked by boiling, steaming, simmering, frying or baking.
Egg-fried Rice
Firstly from China's ancient western regions, egg-fried rice has now become part of Chinese people's daily food. Famous for its pleasant smells, soft taste and handsome appearance, one can easily find this popular dish anywhere in China, from high class hotels to family-run restaurants on the street. While it is fairly easy to make, there are some points that should be kept in mind: use left-over rice rather than newly cooked rice for better taste.

24、Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【1】We can infer from the text that humans and animals _________.
A. depend on one sense in choosing food
B. are not satisfied with their food
C. choose food in similar ways

26、阅读下面短文，根据其内容写一篇60词左右的内容概要。
Artificial intelligence(AI)teachers can provide customized teaching for students to meet their unique requirements through analyzing data and deep learning.In the future, they may replace human teachers for basic teaching tasks.Since some students may find it and put new power into traditional teaching patterns.An educational system providing customized teaching centered on students represents the future trend of AI education.
China's AI education has developed rapidly in recent years with the rise of several thousand relevant companies.Currently,AI teachers are able to help students leamn pronunciation,analyze their condition,guide them to learn independently,and even grade writing assignments. Some foreign AI educational systems have been introduced into several domestic schools and have worked well on trial.
However,the promotion of AI education is still facing several difficulties in practice such as low technological levels,inadequacy of data and lack of funds.AI education still depends largely on human teachers' work.Most importantly,it conflicts with current educational patterns because the courses developed by foreign countries are not suitable for Chinese exam-oriented education.Teachers may also find it hard to change their original roles in classrooms since easing control on classes may make them seem irresponsible.These problems need to be handled before the mass promotion of Al education.
With AI teachers,the original teacher-centered classes will be transformed into student-centered ones where teachers only organize the class and provide guidance.Since teachers are supposed to not only equip students with knowledge but also shape their values and help them develop creative abilities,AI teachers will not replace human teachers but will only pose higher requirements of teaching.A combination of AI teachers and human ones can create the best future for Al education.
