Research has found that storing crucial pieces of information on an electronic device does not rot your memory skills and can actually increase your ability to remember things you would otherwise forget. Storing important information or smartphones may free up our own memory to store a larger amount of less crucial information, allowing us to keep more in total across our internal and electronic memory banks.

Researchers took 158 participants aged between 18 and 71 and showed them up to 12 numbered circles on a screen. Some of the circles would briefly appear pink or blue before all fading to a yellow colour, indicating that they had to be dragged to either the pink side or the blue side of the screen at a later point.

Some of the circles were classed as “high value”, some as “low value” and some as zero value. Users had to remember which side of the screen to drag the circles to in order to earn points. In some of the experiments they had to rely on their own memories. In others, they could set an electronic reminder on a device.

Researchers found subjects tended to use digital devices to store information about which were the highest-value circles. This led to an 1896 increase in accuracy when placing these circles. They also found, to their surprise, using electronic reminders for high-value circles led to a 27% increase in accuracy when differentiating from memory between the low and zero-value circles, even when no electronic reminders had been set for these.

The study said that when people store important information on an external device, their brains tend to delete it from their “internal memory”, reallocating (再分配) that space for “low-value content”.

“The results show that external memory tools work. Far from causing digital dementia, using an external memory device can even improve our memory for information that we never saved. But we need to be careful that we back up the most important information. Otherwise, if a memory tool fails, we could be left with nothing but lower-importance information in our own memory.”

1. What do the underlined words “electronic memory banks” probably refer to?
A.People’s brains.B.To-do lists.
C.Self-service banks.D.Cellphones.
2. How do volunteers earn points in the research?
A.By changing the color of the circles.
B.By moving the circles to the right side.
C.By remembering the number of the circles.
D.By classing the circles according to their values.
3. What will happen to important information after it is stored in digital devices?
A.It will be regarded as low-value content.
B.It will be removed from people’s brains.
C.It will be grouped automatically based on importance.
D.It will be well-preserved despite the failure of digital devices.
4. What can be a suitable title for the text?
A.Information Age: Phones Are Everywhere
B.Promising Future: Phones Shape the World
C.Note to Self: Phones Don’t Rot Memory
D.Controversial Issue: Phones Act as a Double-edged Sword

【推荐1】Imagine you have made plans with a new friend to talk on the phone. You called, but there was no answer—and you didn't get a call back. What happened? Perhaps she got held up by caring for her children or an important task. Perhaps she didn't want to meet but didn't take the time to call off. Or maybe she had a busy week and simply forgot to write down your meeting time. Or it was possible that you called the wrong number.

In social situations like these, our minds can offer a variety of explanations, ranging from ones that are kind to ones that put the blame on the other party. Psychologists refer to this as our attributional style. Past research has found that individuals with a hostile attributional style— that is, who tend to think others' action is a result of bad intentions— tend to be less satisfied with their relationships.

According to a new study in the Journal of Happiness Studies, they're also generally less happy. That means that all those little assumptions we're making about other people might be something we can work on to improve our well-being.

In the study, 707 participants from the United States, Poland, and Japan were asked to analyze situations like the one above. Participants then rated the situation on three factors: how much they thought the other person acted purposely, how much blame they put on them, and how angry they were, as a measure of hostile attributions. They also filled out a questionnaire about the degree they considered themselves a happy person.

The researchers found that people who gave others the benefit of the doubt all the time were happy, compared to the participants who always blamed others. People who only sometimes gave others the benefit of the doubt were also happier.

The researchers can't say for sure whether seeing people as unfriendly directly lowers our happiness, or whether unhappy people are just more likely to make hostile attributions in the first place. However, this study does suggest the possibility that giving people the benefit of the doubt can improve our relationships and our well-being.

Dorota Jasielska, assistant professor at the Maria Grzegorzewska University in Warsaw and lead author of the paper, suggests that we start by developing positive and trusting social relationships. When we find ourselves surrounded by warmth and support, it can help us to see the social world in a more positive light. If you feel lonely, volunteering or joining friendly welcoming organizations can be a good way to broaden your social circle.

Another important strategy is to have open and direct communication. Instead of letting your anxieties get worse, Jasielska explains, it may be better to simply talk to people about their confusing behavior.

So the next time a friend calls off plans or forgets to text back, consider giving them the benefit of the doubt and waiting to hear their side of things before jumping to conclusions. Assuming others have good intentions— particularly the people we already know and love—will make the world seem like a friendlier place.

A.To introduce the topic of the text.B.To give some background information.
C.To present findings of recent research.D.To provide answers to a difficult problem.
2. What do people with a hostile attributional style tend to do?
A.To judge others' actions negatively.B.To be unwilling to trust others' words.
C.To try hard to control others' behavior.D.To blame others for their own mistakes.
3. What do the last two paragraphs mainly talk about?
A.Ways to have effective communication.B.Importance of making friends in daily life
C.Methods for improving our social relationship.D.Advice on dealing with confusing social behavior

文章大意:这是一篇说明文。文章介绍了科学家们已证实了蚯蚓有助于保持土壤健康,蚯蚓对全球粮食生产做出贡献,我们需采取措施保护蚯蚓。

【推荐2】Most gardeners know that earthworms (蚯蚓) help keep soils healthy. Now scientists have assessed just how important their underground activities are to global food production — and how to protect them.

In research published this September, scientists found that earthworms may contribute to more than six percent of global grain production every year, because of their crucial role in soil ecosystems.

Worms help to break down dead plant material, releasing nutrients plants need to grow, and their tunneling (挖隧道) helps plant root growth. Evidence suggests they also help plants protect themselves against common soil-related diseases by stimulating their defenses.

“Their contribution may even be larger,” said Steven Fonte, an associate professor at Colorado State University in the United States who co-authored the research. “This is because earthworm populations are likely underestimated in many places, especially in the tropical areas, due to a lack of research and funding in the global south.” he explained.

The authors said their findings represent one of the first attempts to quantify the contribution of a beneficial soil organism to global agricultural production. They found that earthworm contribution is especially high in the global south, contributing about 10 percent of total grain production in sub-Saharan Africa and roughly eight percent in Latin America and the Caribbean. They owed this to soils there generally having higher acid and clay content and being less exposed to fertilizer (肥料), increasing the role earthworms play in plant growth.

Scientists figured that earthworms are threatened by today’s intensive and chemical-heavy agricultural techniques. Agricultural and environmental policies should support earthworm populations and soil biodiversity to promote more sustainable development. Measures could include reducing the use of land for growing crops, cutting the use of poisonous chemical substances, and increasing the application of worm food sources. “Soils are estimated to contain approximately half of all biodiversity on the planet and are incredibly important for biodiversity conservation efforts,” Fonte said.

1. How do earthworms benefit the soil ecosystems?
A.By increasing the number of plant roots.B.By reducing fertilizer’s effects.
C.By helping plants against certain diseases.D.By breaking down nutrients.
2. What makes earthworms contribute more in the global south?
A.The good soil quality.B.The advanced agriculture.
C.The supportive policy.D.The earthworm-friendly climate.
3. What is a possible way to protect earthworms?
A.Expanding the farming land.B.Providing healthy food for them.
C.Banning intensive agriculture.D.Using fewer harmful chemicals.
4. What can be a suitable title for the text?
A.Earthworms: An Assistant to Soil Health
B.Earthworms: Their Threats and Conservation
C.Earthworms: The Decisive Factor in Biodiversity
D.Earthworms: A Contributor to World Food Production

文章大意:本文是一篇说明文。本文主要讲了闲聊对每个人都非常重要,作者重点阐述了闲聊的好处。

【推荐3】Small talk, also called chitchat, is short conversations people have with others, while they wait in line at the store, at family events or work. Many people find these small conversations about random topics difficult. Some people say they hate it. Others say small talk is a waste of time. They may even call it idle chitchat or idle chatter, meaning it doesn’t do anything, so they think little of it.    1    .

These exchanges can open doors that may lead to larger, more meaningful conversations. When you first meet someone or talk to someone you don’t know well, it would be awkward to begin a conversation about a really deep topic.    2    Let’s say you make small talk with someone at a party. But they only want to talk about their cats. Then you can talk about animals together first, which may lead the conversation to the way you want.

    3    Chatting with a colleague about his child may help you to understand more of his life outside the office. This could help build healthy work relationships.

Small talk could even help your larger communities----your relationships with neighbors and colleagues. Exchanging a recipe with a neighbor may make her noises upstairs easier to live with.

    4    Most people said they do not talk to strangers while travelling on a subway. Researchers at the University of Chicago then asked some participants in a study to talk to people while communicating to work on a train. They found that those who made small talk with strangers were happier than those who sat alone.    5    Maybe your life will become more cheerful just because of it.

A.Small talk may make you happier.
B.So why not try talking to someone?
C.Small talk can give you the chance to start.
D.However, some people are not good at small talk.
E.However, small talk is of great importance to everyone.
F.Small talk can also increase your feeling of understanding.
G.It’s easy to start a conversation by sharing the same experience.
