The Secret Language of Plants
植物的秘密语言
Talking plants have long been a thing of myths and legends.
会说话的植物一直以来都被认为是神话和传说。
Many cultures have stories of talking trees that give advice as well as warnings to people.
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。
Alexander the Great and Marco Polo were said to have visited such a tree in India.
据说亚历山大大帝和马可·波罗曾在印度见过这样的一棵树。
And in some modern stories, such as the film Avatar, trees can communicate with animals and people.
在一些现代故事中，比如电影《阿凡达》中，树木是可以与动物和人进行交流的。
With us long believing that talking plants are fantasy, new research has revealed something amazing: it appears that plants can communicate after all.
长久以来，我们一直认为会说话的植物是不可思议的，而最新的研究却揭示了一些令人震惊的事情：植物似乎真的可以交流。
词句自测 ①myth n. (古代的)神话 ②legend n. 传说，传奇(故事) ③“主(Many cultures)谓(have)宾(stories)”。介词短语of talking trees是stories的后置定语；现在分词talking作前置定语，修饰trees；that give advice as well as warnings to people为定语从句。
It has been known for some time that plants use chemicals to communicate with each other.
人们早就知道植物使用化学物质来相互沟通。
This happens when a plant, say a bean plant, gets attacked by insects.
当植物，比如豆科植物，被昆虫袭击时，就会发生这种情况。
The plant releases tiny amounts of chemicals from the leaves that are being eaten.
这种植物从被吃掉的叶子中释放出微量的化学物质。
This is like a warning, or a call for help: “I'm being attacked！”
这就像一个警告，或者一个求助信号：“我被攻击了！”
When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals.
当另一种豆科植物从它受伤的邻居那里察觉到化学物质时，它开始释放自身不同的化学物质。
Some of these chemicals drive insects away.
其中一些化学物质可以驱赶昆虫。
Others attract insects—the wasps!
另外一些(化学物质)吸引昆虫——黄蜂！
The wasps kill the insects that are eating the bean plants.
黄蜂杀死吃豆科植物的昆虫。
Scientists hope to learn more about this plant warning system, so that we can use it to grow crops without pesticides.
科学家们希望更多地了解这种植物预警系统，这样我们就可以用它来种植没有杀虫剂的作物。
词句自测 ④detect v. 发现，察觉(尤指不易觉察到的事物) ⑤wasp n. 黄蜂 ⑥pesticide n. 杀虫剂，农药 ⑦“主(It)谓(has been known)”。for some time作时间状语。It是形式主语；that plants ... each other是主语从句作真正的主语。从句结构是“主(plants)谓(use)宾(chemicals)”， to communicate with each other是不定式短语作目的状语。
More surprisingly, plants also use sound to communicate.
更令人惊讶的是，植物也能用声音交流。
People can't hear these sounds, but plants are making them.
人们听不到这些声音，但植物正在发出这些声音。
Some plants make noises with their roots. Corn and chilli plants do this.
有些植物用根发出声音。玉米和辣椒就是这样。
They also “listen” to the noises from other plants.
它们也“听”来自其他植物的声音。
A chilli plant can tell if a neighbouring plant is helpful, or unfriendly.
一株辣椒可以分辨出附近的植物是否是有帮助的，还是不友好的。
Some trees make clicking noises when there is not enough water, indicating drought is arriving.
有些树没有足够的水分时就会发出滴答声，说明干旱即将发生。
词句自测 ⑧root n. 根 ⑨chilli n. 辣椒
Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest.
最令人惊讶的是，植物有一个惊人的沟通系统，几乎可以连接森林里的每一株植物。
Scientists call this system the “wood wide web”．
科学家称这个系统为“树联网”。
It is in some ways similar to the Internet we use.
它在某些方面和我们使用的互联网是相似的。
While the Internet is a worldwide network of computers linked by cables and satellites, the wood wide web is linked underground by fungi.
互联网是一个由电缆和卫星连接的全球计算机网络，而树联网是由地下真菌连接的。
This fungal network links the roots of different plants to each other.
这种真菌网络把不同植物的根相互连接起来。
Using the wood wide web, plants can share information and even food with each other.
利用树联网，植物之间可以互相分享信息甚至食物。
For example, some pine trees can send food to smaller pine trees to help them grow.
例如，一些松树可以把养分输送给小松树来帮助它们生长。
词句自测 ⑩link v. 把……联系起来；连接 fungus n. 真菌 fungal adj. 真菌的 “主(plants)谓(can share)宾(information and even food)”。Using the wood wide web是现在分词短语作方式状语。
But just like our own Internet, the wood wide web has its own version of “cybercrime”．
但就像我们自己的互联网一样，树联网也有它们自己的“网络犯罪”。
Plants can steal food from each other, or spread poisons to attack other plants.
植物可以互相偷取食物，或者传播毒素来攻击其他植物。
Perhaps one day scientists will learn how to create a “firewall” to help prevent these attacks within the wood wide web.
也许有一天，科学家们将学会如何创建一个“防火墙”来帮助防止这些树联网内的攻击。
Scientists are learning more every day about the secret ways in which plants talk to each other.
科学家们每天都在更多地了解植物之间相互交流的秘密方式。
Who knows Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves.
谁知道呢？也许有一天，我们会对植物间的交流有足够的了解，从而能够亲自和它们“交谈”。
词句自测 cybercrime n. 网络犯罪 “主(scientists)谓(will learn)宾(how to ... ‘firewall’)”。to help prevent these attacks within the wood wide web 是目的状语。

Ⅰ 阅读
Square foot gardening is a type of gardening made popular by Mel Bartholemew. It is based on the idea that the wide rows in traditional gardening are a waste of time, work, water and area.It shows that quality vegetables can be grown in less space with less work. In this method, the garden space is divided into “beds”. Each bed is 4’×4’ (16 sq ft) (120cm×120cm, 1.4 m2). The beds are separated by paths (小路). These beds are further divided into squares of about one square mon spacing is one plant per square for larger plants such as broccoli, four per square for medium large plants like lettuce, nine per square for medium small plants like spinach, and sixteen per square for small plants such as onions and carrots. The weeds (杂草) are removed from the beds and the plants are watered from the paths. This stops the soil from being compacted (压紧)．
Benefits of square foot gardening：
Much less work. Normal gardening needs heavy tools to loosen the soil. In this method, the soil is never compacted and it remains loose.
Water savings. The loose ground holds the water better. This type of garden needs water less often than other methods. Also, water is placed very near the plant roots. Less water is wasted.
Very few weeds. The vegetables form a living mulch (覆盖物) and shade out many weeds before they can start to grow.
Pesticides (杀虫剂) are not needed. Natural ways to keep pests away work very well in a close space. Many different types of plants in a small area also stop plant diseases from spreading easily.

Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from textbooks. Sam was a kind hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn't wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel (铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher's command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.
注意：
1．续写词数应为150个左右；
2．请按如下格式在相应位置作答。
A few days later, a storm damaged some young trees in the community. The neighbours praised Sam for what he had done.
写前导读：本文是一篇记叙文。Sam (山姆)喜欢探索大自然，几天后，一场暴风雨把社区的很多树破坏了，他做了什么？他感受如何？
[精彩范文]
A few days later, a storm damaged some young trees in the community. After seeing what had happened, Sam felt that it was time for him to put the skills of planting trees he had learned to use. He went home and told his mom he wanted to save those trees. So he took the tools that he had used to plant the trees. With the skills taught by his teacher, he worked with his mom to replant those trees. They helped the trees survive.
The neighbours praised Sam for what he had done. Sam told them about his experience of planting trees. But he owed all the kindnesses to his teacher and mother. He explained that because of his teacher and mother, he learned the skills and saved the trees. The neighbours were very happy to hear that. They said Sam was a role model and that they would ask their children to learn the skills from Sam. Sam felt proud and decided to develop a better community and protect the environment with them.

人们早就知道植物使用化学物质来相互沟通。
This happens when a plant, say a bean plant, gets attacked by insects.
当植物，比如豆科植物，被昆虫袭击时，就会发生这种情况。
The plant releases tiny amounts of chemicals from the leaves that are being eaten.
这种植物从被吃掉的叶子中释放出微量的化学物质。
This is like a warning, or a call for help: “I'm being attacked！”

Ⅰ 阅读
Square foot gardening is a type of gardening made popular by Mel Bartholemew. It is based on the idea that the wide rows in traditional gardening are a waste of time, work, water and area.It shows that quality vegetables can be grown in less space with less work. In this method, the garden space is divided into “beds”. Each bed is 4’×4’ (16 sq ft) (120cm×120cm, 1.4 m2). The beds are separated by paths (小路). These beds are further divided into squares of about one square mon spacing is one plant per square for larger plants such as broccoli, four per square for medium large plants like lettuce, nine per square for medium small plants like spinach, and sixteen per square for small plants such as onions and carrots. The weeds (杂草) are removed from the beds and the plants are watered from the paths. This stops the soil from being compacted (压紧)．
Benefits of square foot gardening：
Much less work. Normal gardening needs heavy tools to loosen the soil. In this method, the soil is never compacted and it remains loose.
Water savings. The loose ground holds the water better. This type of garden needs water less often than other methods. Also, water is placed very near the plant roots. Less water is wasted.
Very few weeds. The vegetables form a living mulch (覆盖物) and shade out many weeds before they can start to grow.
篇章导读：本文是一篇说明文。文章介绍了平方尺菜园的操作方法和益处，以及各种植物生长的状况。
Pesticides (杀虫剂) are not needed. Natural ways to keep pests away work very well in a close space. Many different types of plants in a small area also stop plant diseases from spreading easily.
1．Why is the gardening called square foot gardening
A．Because vegetables are grown in the squares.
B．Because you can grow vegetables anywhere by using it.
C．Because the smallest bed in it is only one square foot.
D．Because the places where vegetables are grown are too small.
解析：推理判断题。根据第一段中的“It shows that quality vegetables can be grown in less space with less work. In this method, the garden space is divided into ‘beds’．”以及“These beds are further divided into squares of about one square foot.”可推知，它被称为平方尺菜园是因为：最小的苗床只有一平方英尺。故选C。
2．What can we infer from the text
A．Loose soil is good for plant growth.
B．Onions and carrots need more space.
C．Compacted soil is important to some plants.
D．Square foot gardening needs some heavy tools.
解析：推理判断题。根据第一段最后一句和下文“Normal gardening needs heavy tools to loosen the soil.”可推知，松散的土壤有利于植物的生长。故选A。
3．Why are there fewer weeds in square foot gardening
A．Because weed killers are used.
B．Because weeds can't get sunlight.
C．Because weeds are short of water.
D．Because weeds have been removed.
解析：细节理解题。根据“Benefits of square foot gardening”的第三条可知，蔬菜遮住了杂草的阳光，所以杂草很少。故选B。

Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from textbooks. Sam was a kind hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn't wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel (铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher's command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.

[精彩范文]
A few days later, a storm damaged some young trees in the community. After seeing what had happened, Sam felt that it was time for him to put the skills of planting trees he had learned to use. He went home and told his mom he wanted to save those trees. So he took the tools that he had used to plant the trees. With the skills taught by his teacher, he worked with his mom to replant those trees. They helped the trees survive.
The neighbours praised Sam for what he had done. Sam told them about his experience of planting trees. But he owed all the kindnesses to his teacher and mother. He explained that because of his teacher and mother, he learned the skills and saved the trees. The neighbours were very happy to hear that. They said Sam was a role model and that they would ask their children to learn the skills from Sam. Sam felt proud and decided to develop a better community and protect the environment with them.
