It’s not every day that United States history mixes with microbes(微生物) in the soil.But when the grassland on the National Mall in Washington,D.C.was replaced,it offered scientists the opportunity to study changes in the soil beneath.
The work focused on the bacteria present in the soil.To the researchers’ surprise,the communities of microbes did not change a lot before and after the replacement.These communities in the soil are known as the soil microbiome(微生物群).
“My lab is interested in how microbes can move around in the environment,and how they change and adapt as a result of this movement,” explains Jo Anne Crouch,the lead author of the study.“We thought that the new ‘imported’ turf(草皮) from New Jersey would introduce different communities of bacteria to the National Mall.However,we found that they weren’t significantly different.”
Crouch’s work focused on turf grass,defined as a large area of green grass.It is made up of the grass,its roots,and the soil and microbes found with them.
Think of the soil microbiome as similar to the collection of microbes found in the human body.When the microbes are out of balance,it can make someone sick.Crouch says it’s the same for the soil microbiome.Many of the worst diseases in crops or other environments are linked with changes in the soil microbiome.
Additionally,Crouch says that even though the changes between the soils were small,scientists are also starting to appreciate that sometimes a really important microbe is a rare one.This means it would be hard to observe but could greatly affect how the groups function as a whole.“Agricultural areas and other natural spaces are highly and easily hurt by negative changes,” she says.“Microbiomes offer an almost entirely new opportunity to influence interactions among plants and microbes to improve plant productivity and health.”
1.Why did the researchers feel surprised when they focused on the bacteria in the soil
A.More bacteria appeared in the soil.
B.Microbes were replaced obviously.
C.Soil microbiome almost remained stable.
D.The soil microbiomes damaged the environment.
2.By studying the turf grass,what did Crouch and her team find
A.Microbes grew faster in their own community.
B.Soil microbiomes were different in different places.
C.Turf grass adapted to the environment nearby very soon.
D.Similar communities of bacteria were brought by turf grass.
3.Why did the author mention the microbes in the human body
A.To indicate the two play a similar role.
B.To prove they are both the causes of diseases.
C.To examine the environments people live in.
D.To analyze the changes of human microbes.
4.What does Crouch mean in the last paragraph
A.Microbes are still as hard to observe as before.
B.Studies on microbiomes can be beneficial to agriculture.
C.Scientists are still puzzled about the effect of microbiomes.
D.Too many microbiomes in the soil mean no harm to plants.

The climate change has become an issue that no one can escape from.If the world wants to limit climate change,water shortage and pollution,then we all need to choose “flexitarian (弹性素食)” diets,say scientists.
This means eating mainly plant-based food,which is one of three key steps towards a sustainable future for all in 2050,they say.Food waste will need to be halved and farming practices will also have to improve,according to the study.Without action,the impacts of the food system could increase by up to 90%.Fast on the heels of the landmark report of the Intergovernmental Panel on Climate Change (IPCC) comes this new study on how food production and consumption impact major threats to the planet.
The authors say that the food system has a number of significant environmental impacts including being a major driver of climate change,providing freshwater and reducing pollution through over use of nitrogen (氮) and phosphorus (磷).
The study says that thanks to the population and income growth expected between 2010 and 2050,these impacts could grow between 50%-90%.This could push our world beyond its geographic boundaries.So when it comes to climate change,the authors looked at what they called a “flexitarian diet”.
“We can eat a range of healthy diets but what they all have in common,according to the latest scientific evidence,is that they are all relatively plant-based,” said lead author Dr Marco Springmann from the University of Oxford.
“You can go from a diet that has small amounts of animal products;some might call it a ‘Mediterranean-based’ diet;we call it a ‘flexitarian’ diet.We tried to stay with the most conservative one of these which in our view is the flexitarian one,but even this has only one serving of red meat per week,” he added.
If the world moved to this type of diet,the study found that greenhouse gas emissions (排放) from agriculture would be reduced by more than half.
8.What will happen if the new diet is popular globally
A.The climate will become warmer.
B.The food consumption will increase.
C.People will have less greenhouse gas.
D.People will produce more food waste.
9.What is the attitude of the author to the new diet
A.Supportive.
B.Doubtful.
C.Opposed.
D.Indifferent.
10.What benefit will the new diet bring to the world
A.The animals will be saved.
B.People will need more water.
C.The climate change will stop.
D.The pollution will be controlled.
11.What can be called a “flexitarian” diet
A.Eat animal products every meal.
B.Eat plant-based vegetables every meal.
C.Eat mainly vegetables and never eat animal products.
D.Eat plant-based meal mainly and animal products sometimes.

I left England for Sydney in September.It was a career move for my husband,and our 20-year-old daughter was feeling adventurous and decided to come,too.However,just before leaving England,my 79-year-old mother suffered a stroke(中风).Being strong and independent,she continues to live at home with the help of social services.But she couldn’t look after the garden.I thought how wonderful it would be if there was an organisation offering volunteer help.Friends asked me what I planned to do in Australia,and I told them I would be looking for a volunteer position with a gardening charitable organisation.Imagine my surprise when I found just the organisation I had been looking for—Easy Care Gardening( ECG)!
There are several reasons why I volunteer for ECG.Firstly,as a newcomer to Australia I meet many great people who,like me,volunteer some of their time.We cover a large age range,but all love gardens and helping others.
Secondly,through working with ECG I have been lucky enough to explore Sydney’s North Shore that I might not have had the opportunity to visit otherwise.
Finally,there are all those wonderful people we call “clients(客户)” but are more like friends when we visit them often and tend their gardens.What great people I have met,and the stories they have to tell—the family histories,where they come from and the reasons for immigrating to Australia.I find it a privilege to have access to private gardens which,in many cases,have been the joy of their owners for many years.Each one is individual and reflects the character,needs and the history of each family.Indeed,the gardens reflect the multicultural and historical background of Sydney.
12.What made the author choose to be a gardening volunteer
A.The popularity of ECG.
B.The tips of her friends.
C.Her own experience.
D.Her gardening skills.
13.What do the volunteers at ECG have in common
A.They make friends with their clients.
B.They like to explore Sydney’s North Shore.
C.They are of similar ages and backgrounds.
D.They are kind-hearted with the same interest.
14.What does the underlined word “one” in Paragraph 4 refer to
A.Client. B.Garden.
C.Reason. D.Joy.
15.Why did the author move to Sydney
A.Her husband would work there.
B.She planned to volunteer there.
C.She was very keen on adventures.
D.She had to look after her sick mother.

Nowadays people tend to digitalise everything from watches to fridges.It seems you can choose any item labeled as “smart”. 1 .However,there are plenty that can be used to reduce emissions and save money.
If you’re a part of the digitalisation movement,you might be interested in the concept of smart homes.It means that every element of your house can be controlled from a panel on the wall or your phone. 2 .Use your mobile to power them on or off,and you may feel truly modern or truly lazy.Aside from the benefits of living a more comfortable life,this presents an opportunity to cut down on your electrical bills.
Electricity generation today represents 31% of total global fossil fuel use and around 40% of all energy-related CO2 emissions. 3 It is considered as the first step to prevent global climate change.Connect a smart thermometer to the heating and cooling system and set a specific temperature at which the heating begins to work.Doing so,the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied.Similarly,by installing a CO2 sensor,you can have an automated ventilation (通风) system. 4 .
In a 150,000 m2 office complex near Munich,called Campeon,energy costs of up to 117,067 Euro were saved after the use of environmental control devices this year.In this way,they are contributing to a large decrease in CO2 emissions.Clearly,smart homes are about much more than just living a comfortable life. 5
A.It is actually about living a green life.
B.Smart devices have been installed worldwide nowadays.
C.It starts working only when CO2 concentrations reach a certain limit.
D.There seem to be an ocean of such so-called “smart” inventions.
E.Bearing this in mind,measures should be taken to make buildings more energy-efficient.
F.Alternative energy must be discovered before the fossil fuel runs out in the future.
G.This includes basics such as heating and lighting and many other appliances.

I was a volunteer for an organization at the beginning of this year.The organization is aimed at helping children who suffer from cancer.One day,we were asked to raise money for cancer research and program funding at an event.
Since my friend Lisa was also a volunteer for the organization.I went to the event with her.There were many people at the event.After seeing our poster,some people came to us and talked with us.But few people donated money.It was a bit hot that day.Both Lisa and I got really upset.
Half an hour later,Lisa started complaining,“I don’t think we can raise much money today.”
“Don’t worry.The event lasts for three hours.There is still a lot of time left,”I said,though I also thought poorly of our plan to raise much money that day.
While Lisa and I were talking,a little boy of about eight years old came to us.He stood in front of our poster and started reading.
After a while,he asked,“What is cancer ”
I explained what cancer is.Then I said,“Many people around the world are suffering from cancer.It can be really dangerous.More research is needed to learn about it so that people with it can suffer less.That’s why we’re collecting money for it.”
“Do children suffer from cancer,too ”asked the boy.
“Yes. Many children suffer from cancer.Some of them may die.They need help.”Lisa said and I nodded.
Hearing that,the boy became sad.Then the boy asked,“How much money have you collected ”
Both Lisa and I were embarrassed to tell him that we didn’t raise much money.At last,we said,“Not much.”
The boy looked into our donation container and only saw a few one-dollar and five-dollar bills.The boy said nothing after seeing that and left.Then some girls came to us and we started talking with them.Neither Lisa nor I thought the boy would return.However,about twenty minutes later,the boy did return.
Paragraph 1:
The boy happily ran to us and asked,“Would you take a donation from children ”
Paragraph 2:
Both Lisa and I were deeply touched.

【故事续写】
Paragraph 1:
The boy happily ran to us and asked,“Would you take a donation from children ”Lisa and I looked at each other. We couldn’t,believe such a little boy would care. Though we didn’t believe it, we said “yes”.The boy put his hand in his pocket and took out some five-dollar bills.He said,“I just asked for them from my mother.I really want to help the children suffering from cancer.”
Paragraph 2:
Both Lisa and I were deeply touched.We thanked the boy,but he left soon. Looking at his back,both Lisa and I were greatly encouraged.We wanted to try harder to raise money.So instead of just standing there,we went to people and told them about our program.At the end of the day, we raised over three thousand dollars,a lot more than Lisa and I had expected in the beginning.
