21、 The Wall Street Journal recently published an excellent article penned by Wendy Bounds on a hot topic here at MNN: the air-purifying qualities of the common houseplant. Given that the air inside your home can be 2 to 5 times more polluted than the air outside of it, making it clean with plants like peace lily(百合花)and asparagus fern(芦笋蕨)is an economical, artistically pleasing alternative to air purifiers. So, it's been acknowledged that a bunch of pretty potted houseplants can help you maintain a healthier home, but a smarter home?
That's the question in light of a recent study published by the Journal of Environmental Psychology showing that the presence of plants in a room, particularly in an office environment, can shrink attention span(范围). Struggling directive attention (the kind of attention that takes effort) can be refreshed through exposure to naturalistic environments. Basically, taking a walk through the park can clear one's head. But can a head be refreshed simply by being surrounded by houseplants?
To test their theory, the study's authors rounded up a bunch of participants, put some of them in a room with no plants and put others in a room with four plants placed around a desk, and put them all to the same series of tests. First was a Reading Span Test, which involves reading a series of sentences aloud and remembering the last word in each sentence. This task requires that you fluently switch between attention demanding tasks: from reading and memorizing at one moment, to writing and recalling at the next. Next came a proof-reading task followed by another Reading Span Test.
The results? Participants working in the room with the plants improved their performance from the first Reading Span Test to the second while those working in the room lacking in greenery did not. Consequently, the benefits of working among plants is indeed evident.
【1】What do we know from the first paragraph?
A.Staying indoors can help avoid the poorer air outdoors.
B.Houseplants can function as beautiful cheap air purifiers.
C.Planting potted flowers as decorations is very interesting.
D.Air purifiers are the most effective to create a healthy home.
【2】What does the underlined part in paragraph 2 probably refer to?
A.Focus one's attention. B.Disturb one's attention.
C.Weaken one's attention. D.Turn one's attention away.
【3】What does the test prove?
A.Working in nature helps increase productivity.
B.Houseplants will be in great demand in our life.
C.Greenery creates healthier naturalistic atmosphere indoors.

【4】What can be a suitable title for the text?
A.Flowers: Grand Feast to Eyes B.Greenery: Effective Air-purifier

22、Dear Jim O’Connor,
My name is Annie Le and I am writing to you on behalf of the Native Health Community Garden, a group of people working on starting a community garden in the Mesa Neighborhood.
While searching for potential garden locations, we came across your house located at West Southern Avenue. We are asking about the possibility of using your land as the site of our garden.
In general, a community garden is a space where plants are grown and taken care of by a group of people in the community. Community gardens improve the quality of life, offer more chances to talk to each other and beautify neighborhoods while providing green food and therefore reducing the household cost of food.
To ensure the smooth running of the project, elected volunteers would be in charge. You would have access to all these volunteers and they would like to answer any questions you may have.
I have included some general information about community gardens and what they can bring to a community. We would love to speak with you in person or over the phone to discuss what hosting community garden on your land would involve. Issues may include discussing an agreement rental charges, garden rules, and water access. All the costs for the project will be covered by us. We would also like to present to you our vision of this space.
We would very much like to have your support. Thank you for your consideration and please feel free to contact me. Thank you again.
Respectfully,
Annie Le

23、GRODNO, Belarus—The temperature is close to zero in the evening. Several young refugees are washing their hair with cold water by the fire, helping each other trim beards to look better in front of the camera during interviews. At the border between Belarus and Poland, in a forest far from settlements of both countries, many refugees longing for entering Germany and other rich European Union(EU) countries, who are stranded, are struggling in the cold winter with uncertain future prospects.
On the side of the barbed wire stretching for hundreds of meters along the border, children are chasing each other around camping tents and shelters—which are built with branches of trees and dry grass and swaying in freezing winds—laughing. while adults are not so blessed, though.
Two middle-aged men lifted the trunk of a log and then released it to chop the wood by gravity. Making a fire with wood is the only way to keep warm for these people in the harsh winter. Several other refugees are heating a 500 ml thermos on the fire, waiting for a sip of hot water. A father is taking his four-month-old baby to the food tent.
Since earlier this month. thousands of refugees from the Middle East and other regions have arrived at the Belarusian side of the border in an attempt to enter Poland and then Germany to seek asylum. With the increasing number of refugees, Poland has intensified presence of police and border guards to prevent them from entering the country.
The weather is getting colder and people are starting to fall sick, said an Iraqi Kurdish high school math teacher calling himself Karzan, whose family raised 1,000 U.S. dollars to support him to seek asylum in Germany as life in his hometown had become too difficult.
According to Karzan, the intermediary company promised that he would be able to cross the border of Germany three days after arriving in Belarus. He was promised: “Tomorrow the border will open at 3 o'clock in the afternoon, and you can go to Poland and then to Germany. The government promised.”
After checking with Belarusian border guards, the reporter got the answer: "The refugees do not know where this news came from, but rumors are in the air.”
Expressing concern over the current migrant crisis, Russian Foreign Minister Sergei Lavrov said earlier that the Western policy toward the Middle East and North Africa had led to the tensions.

【2】What does the underlined word “intensified” in paragraph 4 mean?

B．Influenced.
C．Indicated.
D．Increased.
【3】What may we infer about Karzan?
A．He came to the border with his family members.
B．He managed to go to Poland and then to Germany.
C．He might be cheated by the intermediary company.
D．He raised 1,000 U.S. dollars with his friends' help.
【4】What can be the best title for the news report?
A．Refugees are longing for entering Germany and other rich EU countries in cold winter
B．Refugees heading for EU countries are stranded at Belarus-Poland border in cold winter
C．Refugees seeking asylum set up shelters at Belarus-Poland border in cold winter
D．Refugees at Belarus-Poland border are hopefully waiting in cold winter
24、 It’s hard to turn down hamburgers, French fries, potato chips and all of the other junk food that seem to call out to us. However, eating too much junk food can harm your body, particularly if you’re between the ages of 10 and 19.
“Junk food shapes adolescent brains in ways that weaken their ability to think, learn and remember. It can also make it harder to control impulsive behaviors,” said Amy Reichelt, a brain and nutrition specialist at Western University, Canada. “It may even up a teen’s risk of depression and anxiety.”
Reichelt and two other researchers found adolescents are more sensitive than any other age group to processed foods with a lot of fat and sugar. Adolescent brains are still developing the ability to assess risks and control actions. The prefrontal cortex is the part of the brain that tells us we shouldn’t eat chips all the time and helps us resist that urge. But this region is the last to mature - it doesn’t fully develop until we are in our early 20s. Meanwhile, teen brains get more active from rewards for a while. The parts of the brain that make us feel good when we do something pleasurable are fully developed by the teen years.
In fact, these regions are even more sensitive when we are young. That’s because dopamine (多巴胺), a natural chemical that lifts our mood when we experience something good, is especially active in adolescent brains. Therefore, the teen brain has two strikes against it when it comes to resisting junk food. “It has a heightened drive for rewards and reduced self-regulation,” said Reichelt.
So, what’s the best way to say no to junk food? Researchers suggest exercise. When we exercise, the brain’s reward system becomes less sensitive to food. Exercise also cause the body to make a protein that helps brain cells grow and boosts connections between the prefrontal cortex and other brain regions. The prefrontal cortex thus can work better to help us make wise decisions and control our impulses.

A．The effects of eating junk food.
B．The causes of favouring junk food.

A．It serves as the sense of taste.
B．It promotes teenagers’ spirits.
