Task 2:Think creatively and critically and answer the questions.
Do you think it’s useful to study the secrets of plants communication?
Why? What can we benefit from it?
As far as I am concerned, it is very important to study this.Because it

The Secret Language of Plants
Talking plants have long been a thing of myths and legends①.Many
cultures have stories of talking trees [1]that give advice as well as
warnings② to people. Alexander the Great and Marco Polo were said to
have visited such a tree in India.And in some modern stories, such as
the film Avatar, trees can communicate with animals and people③.

[3]It has been known for some time that plants use chemicals to
communicate with each other.This happens when a plant, say a bean
plant, gets attacked by⑥ insects.The plant releases tiny amounts of⑦
chemicals from the leaves that are being eaten.[4]This is like a
warning, or a call for help: “I’m being attacked!” When another bean
plant detects the chemicals⑧ from its injured neighbour, it starts to
release its own, different chemicals.Some of these chemicals drive
insects away⑨.Others attract insects — the wasps! The wasps kill the insects that are eating the bean plants.Scientists hope to learn more about this plant warning system, [5]so that we can use it to grow crops without pesticides.

Most surprisingly of all, plants have an amazing system of
communication⑪ [7]that can link nearly every plant in a forest.
Scientists call this system the “wood wide web”.It is in some ways similar to the Internet we use.[8]While the Internet is a worldwide network of computers⑫ linked by cables and satellites, the wood wide web is linked underground by fungi.This fungal network links the roots of different plants to each other.Using the wood wide web, plants can share information⑬ and even food with each other.For example,
some pine trees can send food to⑭ smaller pine trees to help them grow.

参考译文
植物密语
会说话的植物一直是神话传说中的一大元素。在许多种文化中流
传下来的故事里,会说话的树给予人们忠告和警示。据说亚历山大大
帝和马可•波罗曾在印度见过一棵会说话的树。在一些现代故事——
例如电影《阿凡达》中,树可以与人类和动物沟通交流。
我们一直认为会说话的植物只存在于幻想之中,但新研究有了令
人惊奇的发现:植物间似乎确实可以交流。
英 语·选择性必修第一册(WY)
目 录
人们早就知道植物可以利用化学物质进行交流。当一株植物——
比如豆科植物——被昆虫袭击时,就会发生这种情况。正遭受啃食的
叶子会释放出微量的化学物质,这像是警示,抑或求救:“我被攻击
了!”当另一株豆类植物察觉到附近受伤同伴释放的化学物质时,它
自身便开始释放不同的化学物质,其中一些能驱赶昆虫,而另一些则
会吸引另一种昆虫——黄蜂!黄蜂会杀死那些啃食豆类植物的昆虫。
科学家们希望能进一步了解这种植物警报系统,从而将其应用于不用
使用农药的农作物的种植。
英 语·选择性必修第一册(WY)
目 录
更不可思议的是,植物也能用声音交流。虽然人类听不到,但植
物确实正在发出声音。有些植物通过根部发出声响,比如玉米和辣
椒。它们还能“听见”其他植物发出的声响。由此,辣椒可以知道自
己附近的植物是敌是友。还有些树木在水分不足时会发出咔嗒声,以
示干旱就要来了。
最令人惊奇的是,植物拥有一套神奇的信息交流系统,几乎可以
连接起森林中所有的植物。科学家们称之为“植物万维网”。在某种
程度上,它很像人类使用的互联网。互联网是通过电缆和卫星连接的
全球计算机网络,而植物万维网则是在地下通过真菌连接而成的。这
英 语·选择性必修第一册(WY)
目 录
个真菌网络将不同植物的根彼此连接,通过它,植物可以互相分享信
息甚至是食物。比如,某些松树会通过真菌网络向松树幼苗输送养
分,帮助它们生长。但是,像互联网一样,植物万维网也会发生“网
络犯罪”。植物会偷取同伴的养分,或散播有毒物质攻击其他植物。
也许未来某一天,科学家会研究出建造“防火墙”的方法来阻止植物
万维网中的这些攻击。
科学家们每天都在增进对植物间相互沟通的秘密方式的了解。谁
知道呢?说不定哪一天,我们就能足够了解植物沟通的知识,从而亲
自和植物“聊天”了。

To adapt to climate change, some flowers are darkening their color
to protect themselves from the sun’s radiation, new research shows.
The study suggests that over the past 75 years, the ultraviolet
(UV) pigments (紫外线色素) in flowers have increased in response
to rising temperatures and the thinning ozone layer (臭氧层).The
英 语·选择性必修第一册(WY)
目 录
flowers won’t look any different to humans, but insects consider the
higher levels of UV pigments as a darker color, which could be confusing
when they try to find out colorful flowers to land on.
The UV-absorbing pigments in flowers work like sunscreen and
protect sensitive cells from harmful radiation, Matthew Koski, a plant
ecologist at Clemson University, says.He and his team hoped to
determine if changes in pigments were a result of environmental change —
and if so, what were the plants responding to? The team collected
dried, pressed plants across North America, Australia and Europe.In
英 语·选择性必修第一册(WY)
目 录
total, they studied 1,238 samples from 42 different species dating back
to 1941.Then, using a UV-sensitive camera, they photographed
flower petals from each species.Next, they paired the photographs with the historic local temperature and ozone level data from the time the plant was picked to see how the pigment level changed over time.
The researchers found that the changes in pigments differ between
species, a result of the flowers structure.Flowers with open, exposed pollen had more UV-absorbing pigments when ozone levels were low and radiation was high.But flowers with pollen surrounded by the petal responded to temperatures, not ozone levels.
英 语·选择性必修第一册(WY)
目 录
As climate change continues to intensify, these changes in flowers
color can affect plant-insect interactions.When the whole flowers get

(2026•四川成都期中)In oceans across the globe, a tiny jellyfish
(水母) species shows a remarkable death-defying ability.After
reaching sexual maturity, this jellyfish can turn back into its young form
and then mature again — a process similar to a butterfly turning back into
a caterpillar and then changing into a butterfly again.The deep-sea
creature’s life cycle could theoretically be repeated forever, earning this
species, called Turritopsis dohrnii (灯塔水母), the nickname: the
“immortal jellyfish”.
英 语·选择性必修第一册(WY)
目 录
Like a typical jellyfish, T. dohrnii begins its life as a free-
floating larva (幼体) and matures into a branching, plant-like polyp
(水螅体) .From there, multiple young jellyfish grow out of the
polyp and turn into adults.However, the difference is that when an adult
T. dohrnii is damaged or stressed, instead of dying, it absorbs its own
arms and becomes a blob that settles to the sea floor.Over the next day
and a half, this blob transforms into a new polyp, which can then form
more jellyfish.Therefore, though T. dohrnii may be eaten by
predators, it does not die of old age.
英 语·选择性必修第一册(WY)
目 录
A new study compared T. dohrnii to T. rubra, a related jellyfish
species that undergoes normal aging.Compared to its relative,
researchers found that T. dohrnii has twice as many genes that repair and
protect DNA. This allows T. dohrnii to generate more restorative
proteins.Researchers also found differences in several other genes,
including those associated with replication and the stem cell population.
These differences may be key to the jellyfish’s immortality.
英 语·选择性必修第一册(WY)
目 录
Researchers say these findings could help humans — but not in the
exact same way.They believe their study could help find better answers
to the many diseases associated with aging.They also hope a better
understanding of these jellyfish genes might inspire regenerative medicine
for humans.

Ⅱ.阅读七选五
(2026•陕西榆林期中) Soilless farming, as the name implies, is
a type of farming where plants are cultured and grown without the use of
the soil.9. With this method, crops can be planted almost
everywhere.
Due to lacking originality, conventional farming has many
processes and requires the manure (肥料) of chemical mixtures to make
the soil rich in nutrients.Soilless farming has less workload and can
enhance growth.10. Their needs are met throughout life, from seeds
to ripe fruit.
英 语·选择性必修第一册(WY)
目 录
In many soilless farming systems, water is recycled and reused until
the plants are ready to harvest.Hence, soilless farming is an alternative
to dry regions.Additionally, it reduces the physical labor and energy
required from workers.11.
By following standardized steps throughout the entire production
process, soilless farming can supply crops to the market every day,
meeting consumers’ needs.12. They will begin growing crops
locally all year round.In this way, even seasonal produce can be
harvested anytime.

目 录
13. The rate at which pathogens (病原体) attack the farm
will be zero as a result of how the planting environment is concerned,
and if the pathogen ever attacks, the infected plant will be easily
separated to avoid infecting the farm as a whole.Developed countries in
the world are expected to adopt this mode of farming because doing so
reduces the level of food importation and increases the availability of food
in the country.
A. The quality of the harvested food may be controlled.
B. However, soil farming requires more workload.
英 语·选择性必修第一册(WY)
目 录
C. This helps them achieve higher profits while keeping costs very low.
D. After all, food imports might pollute the environment.
E. Nutrients are provided to the plants, majorly in liquid form.
F. Countries relying on food imports see how productive this farming
method is.
G. It is also a systematic technique for growing plants without soil as a
rooting environment.
