●ⅠA
【文章大意】 本文是一篇说明文。文章主要说明了为了避免砍伐树木,麻省理工学院的研究人员开创了一种技术,在实验室里生产类似木材的植物材料。本文解释了其实验过程以及其积极意义。
1.C 细节理解题。根据第一段可知,麻省理工学院的研究人员进行这项研究是为了减少树木损失。故选C。
2.B 段落大意题。根据第二段“In the lab, the researchers first take cells…These cells are cultured in the liquid medium for two days, and then moved to another medium…By adjusting the hormone levels, the researchers can tune the physical and mechanical qualities of the cells. Next…Finally…”可知,第二段按时间顺序讲述了实验室研究的关键步骤。故选B。
3.A 细节理解题。根据第三段“They found that lower hormone levels lead to plant materials with more rounded, open cells of lower density, while higher hormone levels contribute to the growth of plant materials with smaller but denser cell structures. Lower or higher density of cell structures makes the plant materials softer or more rigid, helping the materials grow with different wood-like characteristics.”可知,激素水平影响植物材料的硬度。故选A。
4.B 细节理解题。根据最后一段“This technology can be tuned to meet the requirements you give about shapes, sizes, rigidity, and forms. It enables us to ‘grow’ any wooden product in a way that traditional agricultural methods can’t achieve.”可知,贝伦斯坦认为这项研究具有开创性是因为它革新了制作木制品的方法。故选B。
B
【文章大意】 本文是一篇说明文。文章主要讲述了由于环境变化如栖息地破坏和传粉者多样性的快速减少,一种花种的繁殖系统进化可能导致花朵变得更小,花蜜产量减少,从而更多地进行自我授粉,这对传粉者的行为产生了直接影响。这种进化可能会限制植物对环境变化的适应能力,并可能加剧传粉者种群数量的下降,形成恶性循环。文章揭示了植物与传粉者之间生态关系的潜在演变及其可能带来的生态影响。
5.C 细节理解题。根据第三段“The flowers’ reproductive evolution may be linked to environmental changes such as habitat destruction and rapid ongoing decreases in pollinator biodiversity…”可知,传粉者生物多样性持续下降可能促使花的生殖进化,故选C。
6.A 推理判断题。根据第四段中“…Acoca-Pidolle and his colleagues discovered that today’s flowers are smaller and produce less nectar (花蜜) as a result of increased self-pollination, which has direct impacts on pollinators’ behaviour.”可推知,过去的三色堇更大、花蜜更多是因为它们自花授粉少,故选A。
7.B 推理判断题。根据最后一段“The major message is that we are currently seeing the evolutionary breakdown of plant pollinators in the wild…”可知,花朵生殖进化的变化导致野生植物传粉者的进化正在崩溃,故选B。
8.B 主旨大意题。根据第三段“The flowers’ reproductive evolution may be linked to environmental changes such as habitat destruction and rapid ongoing decreases in pollinator biodiversity…”并通读全文可知,由于环境变化和传粉者多样性的快速减少,开花植物正在更多地进行自我授粉,“开花植物:自我授粉”适合做标题。故选B。

Each year, the world loses about 10 million hectares of forest—an area about the size of Iceland—because of cutting down trees. At that rate, some scientists predict the world’s forests could disappear in 100 to 200 years. To handle it, now researchers at Massachusetts Institute of Technology (MIT) have pioneered a technique to generate wood-like plant materials in a lab. This makes it possible to “grow” a wooden product without cutting down trees.
In the lab, the researchers first take cells from the leaves of a young plant. These cells are cultured in the liquid medium for two days, and then moved to another medium which contains nutrients and two different hormones. By adjusting the hormone levels, the researchers can tune the physical and mechanical qualities of the cells. Next, the researchers use a 3D printer to shape the cell-based material, and let the shaped material grow in the dark for three months. Finally, the researchers dehydrate the material, and then evaluate its qualities.
They found that lower hormone levels lead to plant materials with more rounded, open cells of lower density, while higher hormone levels contribute to the growth of plant materials with smaller but denser cell structures. Lower or higher density of cell structures makes the plant materials softer or more rigid, helping the materials grow with different wood-like characteristics. What’s more, it’s to be noted that the research process is about 100 times faster than the time it takes for a tree to grow to maturity!
Research of this kind is groundbreaking. “This work demonstrates the great power of a technology,” says lead researcher, Jeffrey Berenstain. “The real opportunity here is to be at its best with what you use and how you use it. This technology can be tuned to meet the requirements you give about shapes, sizes, rigidity, and forms. It enables us to ‘grow’ any wooden product in a way that traditional agricultural methods can’t achieve.”

Many flowering plants can self-pollinate (自花传粉), or transfer pollen between their own blossoms for seed generation and reproduction, but most of these plants have relied on pollinators such as butterflies and bees to reproduce. Now—during declines reported in many pollinator populations—a new study on the evolution of one flower species’ mating system has revealed a remarkable change that could worsen the challenges faced by the plants’ insect partners.
The flowers’ reproductive evolution may be linked to environmental changes such as habitat destruction and rapid ongoing decreases in pollinator biodiversity, according to Samson Acoca-Pidolle, who led the study published on December 19 in the journal New Phytologist.
Comparing seeds of wild field pansies (三色堇) collected decades ago in France with the plants’ modern descendants, Acoca-Pidolle and his colleagues discovered that today’s flowers are smaller and produce less nectar (花蜜) as a result of increased self-pollination, which has direct impacts on pollinators’ behaviour.The pansies of the past self-fertilized less and attracted far more pollinators than those of the present, according to the study.
“It seems that it’s only traits (特性) that are involved in plant-pollinator interaction that are evolving,” said Acoca-Pidolle. The changes could restrict the plants’ ability to adapt to future environmental changes and have implications for “all of floral biodiversity”—potentially decreasing flowering plants’ genetic, species and ecosystem variation.
“This may increase the pollinator decline and cause a negative feedback cycle,” study co-author Pierre-Olivier Cheptou told CNN. “If plants produce less nectar, there will be less food available to pollinators, which will in turn accelerate the rate at which the animals’ numbers decrease,” he explained.
“The major message is that we are currently seeing the evolutionary breakdown of plant pollinators in the wild,” said Cheptou, an evolutionary ecologist at the French National Centre for Scientific Research and professor at the University of Montpellier.
( )5.Which of the following may contribute to the flowers’ reproductive evolution
A.Changed behaviour of pollinators.
B.Severe pollution to the habitats.
C.Continuing decline in pollinator biodiversity.
D.Increased plant-pollinator interaction.
( )6.Why were pansies in the past larger and produced more nectar

B.They had a better mating system.
C.They attracted fewer pollinators.
D.They were fertilized by themselves.
( )7.What is the result of the changes in the flowers’ reproductive evolution
A.The flowering plants may have more variations.
B.The evolution of wild plant pollinators is collapsing.
C.The numbers of the animals will increase more rapidly.
D.The plants will adapt to the environmental changes better.
( )8.Which is the best title for the text
A.Pollinator populations: declining
B.Flowering plants: selfing
C.Interdependent relationship: maintaining
D.Floral diversity: increasing

Each year, the world loses about 10 million hectares of
forest—an area about the size of Iceland—because of cutting
down trees. At that rate, some scientists predict the world's
forests could disappear in 100 to 200 years. To handle it, now
researchers at Massachusetts Institute of Technology (MIT) have

pioneered a technique to generate wood-like plant materials in
a lab. This makes it possible to “grow” a wooden product
without cutting down trees.
In the lab, the researchers first take cells from the leaves of
a young plant. These cells are cultured in the liquid medium for
two days, and then moved to another medium which contains
nutrients and two different hormones. By adjusting the hormone
levels, the researchers can tune the physical and mechanical
qualities of the cells. Next, the researchers use a 3D printer to

shape the cell-based material, and let the shaped material grow
in the dark for three months. Finally, the researchers dehydrate
the material, and then evaluate its qualities.
They found that lower hormone levels lead to plant
materials with more rounded, open cells of lower density, while
higher hormone levels contribute to the growth of plant
materials with smaller but denser cell structures. Lower or higher
density of cell structures makes the plant materials softer or
more rigid, helping the materials grow with different wood-like

characteristics. What's more, it's to be noted that the research
process is about 100 times faster than the time it takes for a
tree to grow to maturity!
Research of this kind is groundbreaking. “This work
demonstrates the great power of a technology,” says lead
researcher, Jeffrey Berenstain. “The real opportunity here is to be
at its best with what you use and how you use it. This
technology can be tuned to meet the requirements you give
about shapes, sizes, rigidity, and forms.

B[2024·浙江Z20名校联盟高三第三次联考]
文体：说明文 主题：人与自然 词数：338
An ancient, interdependent relationship that contributes to
food systems and ecosystem stability across the globe could be
changing.
Many flowering plants can self-pollinate (自花传粉), or
transfer pollen between their own blossoms for seed generation
and reproduction, but most of these plants have relied on
pollinators such as butterflies and bees to reproduce.

Now—during declines reported in many pollinator populations—
a new study on the evolution of one flower species' mating
system has revealed a remarkable change that could worsen the
challenges faced by the plants' insect partners.
The flowers' reproductive evolution may be linked to
environmental changes such as habitat destruction and rapid
ongoing decreases in pollinator biodiversity, according to
Samson Acoca-Pidolle, who led the study published on
December 19 in the journal New Phytologist.

Comparing seeds of wild field pansies (三色堇) collected
decades ago in France with the plants' modern descendants,
Acoca-Pidolle and his colleagues discovered that today's flowers
are smaller and produce less nectar (花蜜) as a result of
increased self-pollination, which has direct impacts on
pollinators' behaviour. The pansies of the past self-fertilized less
and attracted far more pollinators than those of the present,
according to the study.

“It seems that it's only traits (特性) that are involved in
plant-pollinator interaction that are evolving,” said Acoca-Pidolle.
The changes could restrict the plants' ability to adapt to future
environmental changes and have implications for “all of floral
biodiversity”—potentially decreasing flowering plants' genetic,
species and ecosystem variation.
“This may increase the pollinator decline and cause a
negative feedback cycle,” study co-author Pierre-Olivier Cheptou
told CNN. “If plants produce less nectar, there will be less food

available to pollinators, which will in turn accelerate the rate at
which the animals' numbers decrease，” he explained.
“The major message is that we are currently seeing the
evolutionary breakdown of plant pollinators in the wild,” said
Cheptou, an evolutionary ecologist at the French National Centre
for Scientific Research and professor at the University of
Montpellier.

【文章大意】本文是一篇说明文。文章主要讲述了由于环境变化如
栖息地破坏和传粉者多样性的快速减少，一种花种的繁殖系统进化
可能导致花朵变得更小，花蜜产量减少，从而更多地进行自我授粉，
这对传粉者的行为产生了直接影响。这种进化可能会限制植物对环
境变化的适应能力，并可能加剧传粉者种群数量的下降，形成恶性
循环。文章揭示了植物与传粉者之间生态关系的潜在演变及其可能
