文章大意:本文是一篇说明文,主要讲述了加州大学的研究人员发现了一个方法,通过用种子精确克隆杂交植物,这个方法可能让贫困农民不用每年购买昂贵的杂交种子,并且保证以后年度的高产。

1 . Plant biologists have found a way that may enable poor farmers to do away with the need to purchase expensive hybrid seeds every year. Researchers at the University of California report that they have solved a long-standing problem of hybrid seeds by making exact clones of the hybrid plants from seeds.

For long, many crops have been grown from high-yielding, anti-disease or climate-tolerant hybrid seeds. But the seeds of hybrid crops do not produce plants with the same qualities during reproduction and hence farmers cannot save the seeds for the next growing season. They end up paying for new hybrid seeds each sowing season. The discovery, long sought by plant researchers, could make it easier to grow desirable high-yielding crops and make them available to the world’s farmers. Farmers could thus replant seeds from their own hybrid plants and enjoy the benefits of high production year after year, the scientists report.

While the discovery would help farmers, it would also impact the commercial interest of the hybrid seed industry. Siddiq, a former Deputy Director General in the Crop Science Division of the ICAR, said at first sight, this might seem like a setback for hybrid seed companies but there would be plenty of things they can still do. “Rice is grown over such a vast climatic and geographical range that specialized hybrids would have to be developed for each region,” he said. The companies, he said, would continue to improve their hybrids. “It will be interesting to see how all this plays out in the years to come.”

Currently, the high costs of producing hybrid seeds are a major barrier to farmers in developing countries, especially South Asia and Africa. Siddiq said if efficiently used, this method could potentially be a game-changer for poor farmers, who would need to purchase hybrid seeds just once and plant the progeny(后代) seeds from their own harvest in the following seasons.

1. What problem do the researchers aim to solve?
A.Farmers’ income.B.Farmers’ costs.
C.Hybrid seeds’ cloning.D.Hybrid seeds’ climate tolerance.
2. What is the disadvantage of the present hybrid seeds?
A.They have a pretty long growth cycle.
B.They tend to be affected by various diseases.
C.They have stricter requirements for sowing time.
D.They fail to reproduce plants with the same quality.
3. What’s Siddiq’s attitude to the commercial interests of the hybrid seed industry?
A.Hopeful.B.Concerned.C.Doubtful.D.Anxious.
4. What is the main idea of the text?
A.The future of the hybrid seed industry.
B.The drawback of cloning hybrid seeds.
C.A method of cloning hybrid plants from their seeds.
D.A means of promoting the specialized hybrid seeds.

Ar Horqin Grassland Nomadic System in the Inner Mongolia autonomous region, listed on the list of Globally Important Agricultural Heritage Systems by the United Nations,     1     (demonstrate) the wisdom of herdsmen to work in harmony with nature.

The     2     (season) movement of herds among different pastures (牧场) plays an important role in maintaining the self-renewal and recovery     3     (capable) of the grasslands. While keeping soil fertility from degrading, the nomadic lifestyle can protect vegetation and make good use of water resources,     4     the growing population of people and livestock, still puts much pressure     5     the grassland resources. Locals have, therefore, come up with ways to avoid overgrazing. With ancestral wisdom     6     (root) in a time of relatively small societies, it may be unable to solve issues today. This is     7     modern planning can help with.

For example, since 2015, under the guidance of the local government of Ar Horqin Banner, the number of sheep and goats in the nomadic system     8     (reduce) from 390,000 to 190,000, while the number of cattle has been increased from 40,000 to 81,000 head. No more than 100,000 sheep are allowed to migrate to the summer camps every year. With     9     (scientific) designed grazing patterns ensuring sustainable development of the grasslands, herdsmen can maintain     10     more balanced relationship with nature.

文章大意:这是一篇说明文。文章介绍了位于坎贝尔岛的世界上最遥远的一棵云杉树从空气中吸收碳来成长,并形成了很大的年轮。科学家们认为通过它的年轮可以揭开气候变化的秘密。

3 . Regarded as the “loneliest tree in the world”, the Sitka spruce (云杉) on uninhabited Campbell Island lately has kept good company with a team of New Zealand researchers who believe it could help unlock secrets of climate changes.

The nine-meter-tall spruce holds the Guinness Record title for the “remotest tree” on the planet. It is the sole tree on the shrubby, windswept island, 700 kilometers south of New Zealand in the Southern Ocean. It’s the only tree for 222km around; its nearest neighbor grows on the Auckland Islands.

Although classified as an invasive species, for radiocarbon science leader at GNS Science, Dr. Jocelyn Turnbull, the tree could be a valuable tool to understand what is happening with the uptake of CO2 in the Southern Ocean. In order to measure CO2 concentrations, taking samples of the atmosphere is the best method, and can be complemented with radiocarbon dating samples of deep water. But it comes with limitations. “You can’t collect air that was there 30 years ago, because it is not there anymore,” Turnbull said, “So we came up with this idea of using tree rings. Plants, when they grow, take CO2 out of the air by photosynthesis (光合作用) and they use that to grow their structures and the carbon from the air ends up in the tree rings.”

This is helpful when there is an abundance of established trees, but those are a rarity in the Southern Ocean. Enter the Sitka Spruce - the south most tree, and the team could find it would offer up good data. “It’s grown a lot faster than anything else in that region and the rings are bigger and easier to separate out and get a record form.”

As for the tree’s lonely status: the description may be in the eye of the beholder. “To get to the tree you have to walk through elephant seals and sea lions, penguins and albatross,” Turnbull said. “The tree doesn’t look lonely …it looks quite content actually.”

1. What is special about the tree?
A.It measures nine meters wide.
B.It is the only tree on a vast land.
C.It grows on the Auckland Islands.
D.It owns the Guinness title for the “loneliest tree”.
2. What can we learn from Paragraph 3?
A.CO2 builds up in the tree rings.
B.The Sitka spruce is a native species.
C.Samples from water are usually inaccessible.
D.Photosynthesis stops the plants absorbing air.
3. What may Turnbull support?
A.The tree coexists with a variety of animals.
B.The tree grows well because of suitable climate.
C.It’s unwise to use tree rings as an indicator of CO2.
D.It’s possible to measure previous CO2 concentrations directly.
4. What is the main idea of the text?
A.Trees are of great significance to scientific research.
B.The “loneliest” tree in the world is not lonely at all.
C.Global warming has a far-reaching impact on creatures.
D.A remote Sitka spruce may help us learn about climate changes.

文章大意:这是一篇记叙文。文章讲述了11 岁的美国女孩Addy Barrett通过各种方式努力拯救大猩猩的故事。

7 . Addy Barrett, an 11-year-old girl from Maryland, the US, is a regular visitor to the zoo, and never gets tired of watching gorillas (大猩猩). “I really fell in love with these smart animals after reading a book about them,” Addy said. “I also learned they were being killed for unnecessary reasons. And I knew I needed to do something.”

Addy is now working to save her favorite animals. She has sold T-shirts and home-made cookies to raise money, and she hosts a party about the gorilla yearly.

Addy asked Meredith Bastian, a zookeeper, about the challenges that wild gorillas are facing and that many people ignore. Bastian said it’s because of habitat loss, climate change and the spread of disease. But there is also the problem of mining. “Some mines in Congo, Africa destroy gorillas’ habitats and make their living conditions worse,” Bastian told Addy.

Addy decided to start the Gorilla Heroes project. She has held fundraisers (筹款活动) hoping to start a conversation on the risks to gorillas. The animals, which are native to Central Africa, are endangered. There are fewer than 900 mountain gorillas and about 100,000 western lowland gorillas in the world. So far, Gorilla Heroes has raised more than $11,000. Addy was recently named a winner of the 2019 Gloria Barton Prize for Young Heroes for her work.

Addy hopes to get close to a gorilla in the wild, but she can’t because she is too young. So for now Addy is sticking to raising money for gorillas.

1. What can we learn about Addy?
A.She seldom goes to the zoo.B.She works hard to save gorillas.
C.She writes books about gorillas.D.She volunteers for a zoo project.
2. What’s Paragraph 3 mainly about?
A.The importance of wild gorillas.
B.The measures for protecting wild gorillas.
C.The pleasant environment for wild gorillas.
D.The reasons for wild gorillas becoming endangered.
3. How is Addy’s Gorilla Heroes project?
A.It is quite dangerous.B.It includes many professions.
C.It is well recognized.D.It has made a difference worldwide.
4. Which of the following can best describe Addy?
A.Proud and childlike.B.Able and generous.
C.Talkative and interesting.D.Easy-going and humorous.

文章大意:本文是一篇说明文。随着信息产业的发展,美国兴起了“土食者”运动,该运动支持食用在本土以可持续方式种植的食物,从而提高人们对可持续生活的意识。

8 . New discoveries and technological breakthroughs are made every year. Yet, as the information industry moves forward, many people in society are looking back to their roots in terms of the way they eat. A “locavore” movement has emerged in the United States. The movement supports eating foods grown locally and sustainably, rather than prepackaged foods shipped from other parts of the world.

Experts hold that eating local has many merits, and is expected to become a trend featuring sustainability. Erin Barnett is the director of Local Harvest, a company that aims to help connect people to farms in their area. By eating local, she argues, people have a better and more personal understanding of the impact their food consumption has on the rest of the world. “There is a way of connecting the point, where eating locally is an act that raises our awareness of sustainable living,” Barnett says.

The United States’ agricultural output is one of the highest in the world, says Timothy Beach, a professor of geography and geoscience at the University of Texas in Austin, Texas. “There’s just no other place on Earth where the amount of input is so productive,” Beach says of American agriculture. “Nobody can cut off the food we need.”

However, the US food system is not sustainable because of its dependency on fossil (化石) fuels, says Beach. Equipment used on “extremely productive” farms is quickly consuming Earth’s natural resources, particularly oil. Additionally, the production of agricultural supplements (补充剂),such as fertilizer, uses large amounts of energy.

The world has used close to half of the global oil supply, Beach says, and the second half will be consumed at an even faster rate because of the growing population and economic development. Although many businesses are experimenting with wind, solar, and biofuel, Beach says there’s nothing that we see on the horizon that can replace it. “There is no way on Earth we are using fossil fuels sustainably. Then we have to reconsider the impact of eating local,” he says.

1. What is the special focus of the “locavore” movement?
A.The development of information society.B.The emergence of new discoveries.
C.The localization and sustainability of food.D.The globalization of eating styles.
2. What is Erin Barnett’s opinion?
A.Agricultural companies have the responsibility to help farmers.
B.Raising the awareness of sustainability is an urgent issue currently.
C.Eating locally can quickly increase the growth of the local economy.
D.The diversity of things can greatly enrich the lives of local people.
3. What’s the main idea of Paragraph 4?
A.The agricultural weaknesses of the US.B.The benefits of fossil fuels.
C.The most productive equipment on farms.D.The consumption of local food.
4. What is the challenge facing the world now?
A.The population is growing too fast.B.Global economy develops rapidly.
C.Eating locally can’t be accepted.D.No suitable energy can replace oil.

文章大意:本文是一篇新闻报道。文章主要报道了北加州大火对学生们的影响。

9 . Children returned to school after a big wildfire in Northern California. But the influence is so huge that it will be some time before the life of students there returns to normal.

Eight schools were lost to the wildfire. Government officials were not sure how many of their nearly 3,500 students would report to temporary (临时的) schools. Some families have left California. Others are staying with friends. It is too far for some of them to drive to one of those schools every day.

There are not enough classrooms for middle and high schools. So for the l3 days before the start of the traditional winter break in the school year, students will learn through independent study. They will be given homework online and be able to visit a special drop-in center in Chico, California. Children going there can get help from teachers or visit other classmates.

Loren Lighthall, a spokesman for one school there, said studying will be less important than dealing with pain and reconnecting with friends. “They don’t have their school, they don’t have their work, they don’t have their friends, they don’t have books and we’re asking them to do homework?” Light hall said. “It’s less important at this point. We’re going to do it. But what is important now is to deal with the pain left.”

Search members have stopped looking for the lost in burned cars and houses. But they remain available whenever there is need for help.

1. What does the underlined “those schools” in the second paragraph refer to?
A.The schools being built.B.The online schools.
C.The 8 schools lost to the fireD.The temporary schools.
2. Why do the students have to learn through independent study?
A.Because there aren’t enough classrooms for them.
B.Because the traditional winter break is coming soon.
C.Because the students want to start a new way of study.
D.Because the teachers ask them to do their homework online.
3. What does Loren Lighthall mean by his words?
A.Students should go to school immediately.
B.It is important to deal with the pain.
C.Students should be given much homework.
D.It is not necessary to study after the fire.
4. What is the main idea of the text?
A.Life of students in North California has come to normal.
B.Search members have not stopped looking for the missing.
C.The wildfire in North California influences students greatly.
D.Classrooms are prepared for students affected in the wildfire.

文章大意:本文是一篇记叙文。一只Boxer-Pit Bull混种狗因参与斗狗被残忍地失去了一只耳朵,被命名为Van Gogh,被送往一个收容所。经过多次寻找主人失败后,一位女子想到了让它当画家,带着它进行创作并举办画展筹款。画展虽然人数不多,但最后Van Gogh的画作全部售出并募集了1000美元善款,最重要的是,它终于被有人收养。

10 . Life was not kind to a sweet Boxer-Pit Bull mix. Dog fighting had cruelly taken away his left ear. In 2019, the 4-year-old arrived at a shelter in North Carolina and was then named Van Gogh. Christy Langley explains he was named after the famous painter “not because he is an artist, but because he is a work of art”. What Langley couldn’t predict was that Van Gogh would actually go on to be a successful artist.

Gartner owns a shelter that helps dogs in shelters that are at risk of being put down. She saw Van Gogh and immediately knew she needed to help him. So, she took Van Gogh in from North Carolina in June 2022. Gartner started telling everyone about the friendly and lovely dog on Facebook, Pet Finder, and Rescue Me, but no one responded.

After months of searching for a new owner, Gartner had a new idea. Why not take Van Gogh’s name literally? Gartner explained, “He certainly had the name and the ear for it.” Gartner got to work, putting some paint on a canvas(油画布), wrapping it in a plastic bag, and coating it with peanut butter(花生酱)as a tasty treat for the pup. It only took five minutes for Van Gogh to lick the plastic-coated canvas clean and for a work of art to be created.

They worked on paintings for about a week and then, Gartner invited people to an outdoor art gallery event on October 23, 2022. Sadly, only two people showed up. The next day, Gartner put out a post on Facebook that she felt bad only two people showed up, and said the rest of the paintings were still waiting for their owners. Suddenly, Van Gogh’s pieces were hot items. After two minutes, the paintings were sold out and Gartner raised around $1, 000 for her rescue. The biggest success of all, though, was that on the last day of the silent sale, Van Gogh was finally adopted(收养).

1. What is Van Gogh?
A.A dog owner.B.A boxer.C.A rescuer.D.A dog.
2. What do the underlined words “put down” mean in Paragraph 2?
A.Killed.B.Expanded.C.Protected.D.Valued.
3. How did Van Gogh create his works?
A.By painting with a brush in his mouth.B.By licking a plastic-coated canvas.
C.By running on a canvas.D.By wrapping a plastic bag.
4. What did Gartner do when she found few people were interested in the paintings?
A.She gave up.B.She invited more people.
C.She tore up all the paintings.D.She posted a post on social media.
