There are many colours in nature. But do you know that a colour has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment(实验).
First, put two objects with the same weight into two boxes. Then cover the boxes. Wrap(包裹) one box with a red piece of paper, the other with a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why does it happen? A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That is to say, every colour has its own weight in our mind. The heaviest colour is red, then blue, green, orange, yellow and white. The scientists told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientists say so? That is because every colour represents a kind of light wave(光波)------ a certain wavelength(波长). It reaches our brain(大脑) through organs(感觉器官)
According to this discovery, scientists say that people accept the colour they like, and refuse the colour they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. If you stay in a room with red windows, wallpapers and furniture(家具) for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only one hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change when we see different colours.Which is the lightest colour in a man’s mind?
| A．Red | B．Blue | C．Green | D．White |
Which of the following is NOT true?
| A．Different colours have different weights in a man’s mind. |
| B．The colour “blue” is the second heaviest colour in a man’s mind. |
| C．People can’t smell the colours. |
| D．The colour you don’t like will keep you healthy. |
What will happen when you get into a cool coloured room from a warm coloured room?
| A．You will feel excited. |
| B．You will be happy and contened. |
| C．Your temperature will fall. |
| D．You will be nervous. |
According to the passage, how long will you feel if you stay in a red room for an hour?
| A．Two hours. | B．Fours hours |
| C．Six hours | D．Eight hours. |

Can plants talk？Modern research has found something amazing：they do communicate with each other.
It has been known for some time that plants use chemicals to communicate with each other.This happens when a plant gets attacked by insects.The plant gives out chemicals from the leaves that are being eaten.This is like a warning，or a call for help："I'm being attacked!"When another plant gets the chemicals，it starts to give out its own，different chemicals.Some of these chemicals drive insects away.Others attract the wasps （黄蜂；蜜蜂）!The wasps kill the insects that are eating the plants.Scientists hope to learn more about this plant warning system，so that we can use it to grow more crops.
More surprisingly，plants also use sound to communicate.People can't hear these sounds，but plants are making them.Some plants make noises with their roots.Corn and chili plants do this.Some trees make clicking noises when there is not enough water.
Most surprisingly of all，plants have an amazing system of communication that can link nearly every plant in a forest.Scientists call this system the "wood wide web".The wood wide web is linked underground by fungi （霉菌）.It links the roots of different plants to each other.It is in some ways similar to the Internet we use.Using the wood wide web，plants can share information and even food with each other.However，it may lead to bad effects.Plants may use it to steal food from each other，or spread chemicals to attack other plants.Perhaps one day scientists will learn how to create a "firewall" to help prevent these attacks within the wood wide web.
Scientists are learning more every day about the secret ways in which plants talk to each other.Maybe one day we will know enough about plant communication to be able to "talk" with them ourselves.
（1）What will plants do when they are attacked by insects？
A.They will kill the insects by themselves.
B.They will control the wasps to kill the insects.

（2）How are the wood wide web linked by fungi？
A.By making noises with their roots.
B.By connecting the roots of different plants to each other.
C.By sharing food and information with each other.
D.By spreading chemicals to each other.
（3）What is the writer's intention of the last paragraph？
A.To give people hope for further studies.

When I was a girl growing up，I cannot once ever remember either my mum or my grandma wasting food.
Anything we didn't eat at one meal was leftovers（剩菜）.I can remember my grandma making a huge pot of potatoes.We would all eat until we were full enough，but there were always about half of the potatoes leftover.A few days later，Grandma would take those potatoes out of the fridge，boil some noodles，add some vegetables and mix them all together.And I also remember when I watched my mum fry bacon （煎培根）for us in the mornings，she would always take the oil carefully and pour it into a bottle.Then she would use it later to add flavor to so many other dishes.I was an adult before I realized that potatoes didn't actually taste like bacon!
I learned their lessons well，and after I grew up，I tried to never waste food myself.I always planned the week's meals ahead of time and only bought what was on my shopping list so that nothing went to waste.Every meal went into our stomachs and any leftovers were later eaten by either myself my boys，my husband or my dogs.To me，throwing food into the bin was just wrong.

Shashiyu was once a poor village in Hebei Province，but now it has changed into a rich and livable place.
In the 1940s，villagers in Shashiyu had little food and few clothes，but they had a strong wish for a better life.Zhang Guishun，the Party secretary of Shashiyu，encouraged his villagers to do their best to pull themselves out of poverty. "In the ancient Chinese story，Yu Gong could move mountains with his strong will and hard work，why can't we？Nobody was born to be poor？" Hearing his words，the villagers decided to make a difference.
Led by the Communist Party of China（中国共产党），the villagers carried water and soil to their village from faraway places to improve their land.From 1966 to.1971，they reclaimed（开垦）lots of land and greatly improved their life.
However，the village encountered a new problem two decades later as the environment became heavily polluted by chemical plants and mine refineries built in 1990s.
The polluting factories were shut down in 2004，and villagers started grape cultivation，which soon became a main industry in Shashiyu.
In 2009，the city﹣level government invested over 1 million yuan（＄152，723）to change the village's exhibition hall into a museum in memory of development efforts made by earlier generations.
After 10 years，the village was called "National Forest Village".
Zhang said that the village started a yearly tourism festival in 2015 to attract travelers to pick grapes. "The grapes could be sold at a better price once Shashiyu becomes famous through this festival.Our villagers can then live even better lives， "he said.

Nature and culture are often seen as opposite ideas.What belongs to nature cannot be the result of human activities and.on the other hand，cultural development is achieved against nature.However，this is not the only opinion on the relationship between nature and culture.Studies in the development of humans suggest that culture，whether taken as an effort against nature or a natural effort，is part of the development of the human species（物种）.
Several modern writers saw the process of education as a struggle（斗争） against human nature.We are born with wild natures，such as eating and behaving in a disorganized way or acting selfishly.Education uses culture as a way to get us out of our widest natures；it is thanks to culture that the human species could learn to adapt（适应） ，progress and raise itself above and beyond other species.
Over the past century and a half，however，studies in the history of human development have shown that the formation of culture is part of the biological adaptation.Consider，for example，hunting（打猎） .It seems to be an adaptation，which allowed humans to move into new and different areas，opening up the opportunity to change living habits.At the same time，the development of weapons（武器） is related to that adaptation—from rocks and stones to a set of hunting tools，and from hunting tools to rules relating to the proper use of weapons.Hunting also seems to be responsible for a whole set of bodily abilities，such as balancing on one foot.Just think of how this very simple thing is closely related to dance，a key expression of human culture.It is then clear that biological development and cultural development are closely tied.
The transmission of culture seems to be directly related to what's in our blood.Just as snails carry their shell，so do we bring along our culture.However，culture is also passed on among people of the same times or among people belonging to different populations.We can learn how to make jiaozi even if we were born from Russian parents in Paris just as we can learn how to speak English even if none of our family or friends speaks that language.
（1）What is Paragraph 2 mainly about？
A.Culture belongs to human nature.
B.Nature teaches humans how to adapt.
C.Humans are supposed to be well organized.
D.Education pushes the human species to progress.
（2）Why does the writer talk about hunting in Paragraph 3？
A.To suggest some possible ways of changing living habits.
B.To stress the importance of tools in humans' struggle for life.
C.To show how culture develops as humans adapt to the environment.
D.To explain why there is a need to call for the proper use of weapons.
（3）The word "transmission" in Paragraph 4 probably means " ".
A.system
B.spread
C.start
D.spirit
（4）What is the writer's opinion on the nature﹣culture relationship？
A.Culture and nature are separate yet balanced.
B.Culture depends much on nature to progress.
C.Nature and culture are different but connected.
D.Nature follows the unwritten rules set by culture.
