The brain function of very late risers and “morning larks(早睡早起的人)” during the hours of the working day is different, according to a study.

Researchers scanned the brains of night owls(夜猫子)with a bedtime of 02: 30 and awake time of 10: 15, along with early risers. The tests performed between 08 : 00 and 20 : 00 found night owls had less connectivity in brain areas linked to keeping consciousness. They were more likely to be scatterbrained and they also had slower reactions and increased sleepiness.

Scientists took 38 people who were either night owls or morning larks (people who went to bed just before 23 : 00 and woke at 06 : 30) and studied their brain function at rest. The volunteers then carried out a series of tasks at various times, from 08 : 00 to 20 : 00, and were asked to report on their levels of sleepiness.

Morning larks were least sleepy and had their fastest reaction time in the early morning tests. They were also found to perform significantly better at this time than night owls. In contrast, night owls were least sleepy and had their fastest reaction time at 20 : 00, although they did not do significantly better than the larks at this time.

The brain connectivity in the areas that predicted better performance and lower sleepiness was significantly higher in larks at all time points, suggesting connectivity in late risers is impaired(减弱的) throughout the whole working day, researchers said.

The lead researcher, Dr Elise Facer-Childs, of the University of Birmingham’s Centre for Human Brain Health, said the findings “could be partly driven by the fact that night owls tend to compromise throughout their lives.” He added, “Night owls during school have to get up earlier, then they go into work and they have to get up earlier, so they’re constantly in conflict.”

Therefore, Dr Facer Childs called for more researches to understand the effects of night owls performing on a work or school schedule to which they are not naturally suited.

1. Which of the following can replace the underlined word “scatterbrained” in Paragraph 2?
A.Unfocused.
B.Satisfied.
C.Recognized.
D.Discovered.
2. What conclusion did the researchers draw from the tests?
A.Morning larks were more tired in the morning.
B.Night owls were more active in the morning.
C.Morning larks perform better all day.
D.Night owls perform better all day.
3. According to Dr Facer-Childs, what should later research concerning night owls focus on?
A.The workings of their brain.
B.The effects of their compromises.
C.Whether they can turn into morning larks.
D.How to help them adapt to the normal schedule.
4. What is the purpose of the text?
A.To solve a problem.
B.To give practical advice.
C.To tell an interesting story.
D.To present a research result.

【推荐1】How to Automate New Habits So That You’ll Keep to Them

Anyone who’s tried to add something new to their routine knows one thing: Building new habits isn’t easy.    1    

The good news: There’s a solution, and it’s called automation.    2    For example: If you want to save more but it seems difficult to achieve, try transferring five dollars to your savings account each time you buy lunch during the week. If you want to do more sports but aren’t motivated to go to the gym every day, try doing 5 pushups after each time you use the restroom.

That sounds easy.    3    “Automation works well in developing new behavior patterns     because it involves the use of positive reinforcement(强化), which is one of the most powerful tools for behavior change,” Kahina Louis, a psychologist, tells Shine.

“As you’re engaging in gradual steps toward your goals, you may quickly start to experience feelings of accomplishment and pride that you’re making the changes you wanted to make,” she says. “Those positive feelings are forms of reinforcement, and you are more likely to continue doing things that reinforce you.”

Along with its positive reinforcement, automation emphasizes the impact of small changes in making a big difference. Though we all love the major successes, the small changes along the way are what get us there in the first step.    4     “As you show yourself each small change you’ve made, you’re giving yourself the message that you are capable of accomplishment,” Louis says. “That feeling and self-belief are extremely helpful to have as you continue toward creating new behavior change.”

    5       Take a look at what things you keep doing throughout the day or course of the week   to decide when to add new automation. Louis says, “For example: If you know that you’re always extremely tired after work, then you might consider picking an auto habit that occurs in   your morning routine rather than in the evening.”

Louis also explains that although you should pick a behavior that occurs frequently enough to maximize the opportunities to build towards your goal, try not to choose an already existing behavior that occurs too often-like checking your phone or drinking of water. “You might not even realize you’re doing it, and may then miss a lot of chances to perform the new habit,” she says.

A.Find your auto habits.
B.It takes time and insistence.
C.But it turns out to be efficient while trying.
D.Consider auto habits that occur at times or places.
E.It’s the small steps that fuel your motivation and self-belief.
F.It is when you add what you’d like to be your new habit onto an existing habit.
G.Building a new habit requires strong mind to help the process go along smoothly.

【推荐2】Why You Should Always Store Apples in the Fridge

To fridge or not to fridge? Have you discovered what foods you should take out of your refrigerator and what unexpected items you should store there?     1    

Apples require a little bit of coolness in order to stay fresh in storage for a longer period of time. Cool temperatures alone are often enough to keep your apples fresh for weeks. Keeping apples in a basket in your kitchen is a good visual reminder to get your doctor-recommended one a day. As it turns out, though, storing apples on your countertop could cause them to go bad weeks sooner than if you put them in the fridge.     2     But if you refrigerate them, they can stay fresh for one or two months. That’s essential for reducing food waste, which is why sellers in the United Kingdom are now required to add a refrigerator icon to the packaging of foods like apples that should be kept cold.

    3     Apples should be kept as cold as possible without freezing them. Ideally, you should store them at temperatures that range from 31 to 35 degrees Fahrenheit. Apples start to freeze at about 29 degrees Fahrenheit.

    4     The freshness drawer of your refrigerator. Keep in mind, though, that you shouldn’t store your apples along with other produce. Apples give off ethylene (乙烯), which can cause other fruits and vegetables to spoil.

If you’re not planning on eating all your apples within a few weeks, you might want to consider the variety you buy.     5     Also, for some reason, the sourer apples store longer than the sweeter apples.

A.How cold?
B.How to store apples?
C.Let’s take apples for example first.
D.Once apples are ripe, they easily go bad.
E.So what’s the best place to store your apples?
F.Usually, at room temperature, apples last about a week.
G.The smaller the apple, and the thicker the skin, generally the longer it will store.

文章大意:本文是一篇说明文。一项新的研究表明,色彩饱和度高的照片使食物看起来更新鲜、更美味,从而增加了用户的消费意愿。

【推荐3】Colour saturation(饱和) refers to the intensity(强度) of the reds, greens and blues. Photos high in colour saturation make food look fresher and tastier to viewers, which increases their willingness to order the menu items, a new study suggests. “In the restaurant business, these results provide a simple method to increase sales,” said Stephanie Liu, lead author of the study and associate professor of hospitality management at the Ohio State University. “On Instagram, it means using the ‘X-Pro Ⅱ’ filter(滤镜) on your food photos rather than the ‘Early bird’ filter. It costs nothing, so it’s an easy win for restaurant marketers.

In one survey, 267 participants were asked to imagine themselves looking through options on an online food-ordering platform. They were shown photos of a poke bowl, a Hawaiian dish featuring fish, vegetables and sauce over rice. They were randomly asked to view one of the four different photos with either high or low colour saturation and either close or farther away visual distance. The food in the more highly-saturated photos looked fresher and tastier to participants, and that led them to be more likely to purchase the food. But colour saturation had a stronger effect when the food appeared more distant in the photos. “When the food is shown close up, it’s already easy for the viewers to imagine how fresh and tasty the food would be,” Liu said. “Colour saturation is not as necessary.”

In the second survey, 222 online participants were asked to imagine they were looking through photos of pizza from a restaurant near their home. They were told they would either be eating alone or with their family. As in the previous study, the food in the colour-saturated photo was always seen as fresher and tastier and one that people would be more likely to buy. But that effect was stronger for people who were told they would be eating alone. “When people are eating with others, the social experience is a big part of what people look forward to,” Liu said. “But when they are eating alone, they focus more on the food itself.”

“These findings are more important now than ever before,” Liu said. “With people ordering online, restaurants have to post pictures of their food on online ordering platforms. They should pay more attention to the photos they post as they do to the text. Colour saturation is one key element they need to focus on.”

1. What is a direct effect of the “X-Pro Ⅱ” filter according to Stephanie Liu?
A.Strengthening the “Early bird” filter.
B.Keeping colour saturation low.
C.Making food in photos more appealing.
D.Increasing the variety of menu items.
2. When does colour saturation function more effectively according to the study?
A.When the food appears farther to the observer.
B.When the poke bowl contains more food.
C.When the food is fresher and tastier in reality.
D.When the visual distance of the food is shorter.
3. What can we know about people eating with others?
A.They take social experience into consideration.
B.They choose food that is easier to obtain.
C.They want the food to be fresher and tastier.
D.They pay more attention to colour saturation.
4. Which is the most suitable title for the text?
A.How Colour Speaks for Menu Items Online
B.How Colour Saturation Affects People
C.How Colour Brings Benefits to Ordering Platforms
D.How Colour in Photos Makes Food Look Tastier
