Water is a necessity of life. Rain, especially, helps plants grow and stay green. But too much rain, especially in cities, can lead to flooding. That can cause waste water systems to overflow and send pollutants into rivers and other waterways. To fight the problem, several cities in the United States are starting programs like rooftop gardens.
A team at the University of the District of Columbia in the nation's capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five "green roofs" for the university. He says he is excited about the project because "it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren't doing anything really became something that was about urban agriculture. " Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects.
In cities, “you don't have that many spaces to choose from and so rooftops are just (unused) space," says Caitlin Arlotta. She is a student in the school's Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. "We also have our own farm experiments," Arlotta said. “ Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best. "
Sandy Farber Bandier helps run UDC's Master Gardener program. It seeks to improve cities and make them beautiful by training people to become Master Gardeners. She says she's been surprised by the garden's output. ”My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need. " She also likes being able to show people who live in D. C. and others beyond the nation's capital what and how food can be grown on a rooftop. “This is the future for food. You grow it here, you prepare it in a commercial kitchen, you distribute through farmers markets,food trucks, and then you recycle. "

Companion planting is the idea that some kinds of plants can help each other grow. Plants that are compatible together generally have similar needs in terms of nutrients, soil and moisture levels.
Advice about which plants are compatible is sometimes based more on tradition than proof. But experts say there is evidence to support certain combinations. These can improve harvests, reduce disease and help with pest control by attracting helpful insects.
For example, some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes（豆科植物）are especially good at this nitrogen（氮）-fixing. Then any crops that share the same space with the legumes can get the nitrogen when the roots are broken down.
Beans and potatoes can also share territory well because their roots reach different levels in the soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil, so they do not complete with plants with shallower roots.
But some plants placed together may harm each other’s development. For example, tomatoes do not like wet soil but watercress does, so you would probably want to keep them separated.
Some kinds of produce should be kept apart even after being harvested. This is because of ethylene gas（乙烯气体）. Ethylene is a plant hormone（激素）that can cause some foods to ripen too quickly. Apples release ethylene gas. Apricots, melons and tomatoes also release a lot of ethylene. Some vegetable are easily affected by ethylene, including asparagus, broccoli, cabbage and cucumbers.
This risk of ripening too soon is why markets often separate high ethylene-producing foods from those that are sensitive to the gas. But if you put an apple in a bag with a green banana, the ethylene from the apple will make the banana ready to eat sooner.
What about peaches, plums and nectarines? These kinds of fruit do not need any help from an apple—they release enough ethylene to ripen themselves. But that does not mean there is no way to get the job done faster.
Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over. Keep the fruit at room temperature, out of direct sunlight. Once the fruit is soft enough, either use it or put it in the refrigerator to keep it from getting too ripe.
1.Companion planting refers to the idea that ________
A. some crops can grow together to benefit each other.
B. some crops have the similar needs of nutrients, soil and water level.
C. some plants can damage each other if grown together.
D. a good farming method to prevent natural disasters.
2.According to the text, ________cannot grow together.
A. beans and potatoes B. tomatoes and watercress
C. legumes and corns D. rice and sugarcane
3.What is the function of ethylene?
A. To improve the quality of fruits. B. To produce a poisonous gas.
C. To keep vegetables fresh. D. To make fruits ripe earlier.
4.The text is most likely to be taken from ________.
A. a newspaper of medicine B. a magazine of biology
C. a journal of agriculture D. a travel report

Alongside air and water, food is a necessity for human beings to survive and thrive. But it’s a lot more than that. As Mariette Dichristina of Scientific American wrote: “The most intimate (亲密的) relationship we will ever have is not with any fellow human being. Instead, it is between our bodies and our food.”
Nowadays, for most people in the world’s wealthiest countries, food is a hobby, an enthusiasm, and even something fashionable.
Turn on the TV in the US, UK or France, and you’ll find at least one channel feeding this popular obsession.
And most of us know at least one person who thinks of themselves as a “foodie”. It’s almost impossible nowadays to check our social media apps without at least two or three photos of delicious meals appearing on our screen.
But behind the fancy recipes and social media bragging (夸耀), many of us forget how much we take food for granted. This is why World Food Day is held each year.
Take Kenya for example. This east African nation has been suffering terrible droughts. The result is that people are beginning to starve. Children in particular are suffering, with some of them even dying.
This may seem shocking to know, especially as many cultures outside of Africa think of food in a completely different way. But even in the UK, families on low incomes are forced to use food banks—European organizations that hand out donated food to those who can’t afford to pay for it themselves.
So what can we do on World Food Day? One good way to spend it would be to feel humble and appreciate what we have. After all, food is essential for survival, but not everyone is as lucky as we are when it comes to dinner time.
1.According to Mariette Dichristina, what has the closest relationship with us?
A.Air. B.Water.
C.Food. D.Human beings.
2.What does the underlined word “foodie” in Paragraph 4 probably mean?
A.Delicious food. B.A person fond of food.
C.A social media app. D.A photo of delicious meals.
3.Who can get help from food banks?
A.Poor people in the UK. B.Poor people in Africa.
C.Starving children in Kenya. D.People in the drought-stricken.
4.What’s the best title for the text?
A.Treat Food as a Hobby B.Time to Appreciate Food
C.Food Shortage in Some Countries D.How to Spend World Food Day

Years ago, I into a service station to get some gas. It was a day, and I was feeling great. As I walked into the station to pay for the gas, the attendant said to me, “You don’t look well.” This took me completely by . A little less confidently, I told him that I had never felt better. Without hesitation, he continued to tell me how bad I looked and that my skin appeared .
By the time I left the service station, I was feeling a little . About a block away, I pulled over to the side of the road to look at my face in the mirror. How did I feel? Did I look that ? Was everything all right? By the time I got home, I was beginning to feel a little . Had I picked up some rare disease?
The next time I went into that gas station, feeling again, I figured out what had happened. The place had recently been painted a bright but disgusting yellow, and the light reflecting off the walls made everyone inside as though they had hepatitis(肝炎)! I wondered how many other folks had reacted the way I did. I had let one short with a total stranger change my for an entire day.

There’s no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there’s little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?
You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.
So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?
The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.
The truth is, there is no magic standard for hydration—everyone’s need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you’ll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you’re thirsty.
1.How does the author support the underlined sentence in Para 1?
A. By providing facts.
B. By asking a question.
C. By making a comparison.
D. By putting forward suggestions.
2.According to the “8 X 8” rule, how much water should we take in a day?
A. 8 ounces B. 64 ounces
C. 91 ounces D. 125 ounces
3.What’s the disadvantage of the “8 X 8” rule?
A. The water from both food and other beverages is ignored.
B. It includes the amount of water from both food and beverages.
C. It does not take water from drinks into account.
D. It overlooks the fact that we take in 90% of the water from fruits.
4.What can we infer from the final suggestion?
A. A man doing tiring physical work drunks less than 3.7 liters a week.
B. A person in good health drinks whenever he feels thirsty.
C. An overweight male in a hot summer drinks 125 ounces every two days.
D. A female eating a lot of watermelons drinks more than 91 ounces daily.
