In late 2022, Matthew Pittman and Eric Haley carried out three studies on Americans aged 18-65 to test how people in different situations react to ads differently.

The control group in each study was asked to just look at an ad. The second group had to memorize a nine-digit number and then look at an ad. The third group looked through their Instagram updates for 30 seconds before looking at an ad. The first study used an ad for a meal preparation service, the second was for ice cream and the third was for coffee beans. The ad photos and introductions were the same for everyone in each group, with only the number of likes being different. Participants may see an ad with a few hundred likes or tens of thousands of likes. After viewing the ad, each participant rated how willing they would be to buy the product. The group that used Instagram first was the most likely to want to buy the product when there were lots of likes.

In the second study, participants were asked why they wanted to buy the product and those in the control group gave simple, reasonable answers for their choice. “I was thinking of the taste of the ice cream and how delicious it would be.” Or “I like the ad. It’s simple and clean. It gets straight to the point.” However, most of those who had viewed social media content for 30 seconds gave answers that made no sense. For example, some gave one-word answers like “food” or “plate”. Researchers refer to this as “cognitive overload”.

Then the researchers further developed their study of the ad for coffee beans. And they discovered that those who often drank coffee carefully considered many factors, like the type of the beans and their country of production. So even when these people were in a mental fog, they were not convinced by ads with a large number of likes.

By understanding how they might be influenced by social media in unconscious ways,   consumers can be more thoughtful and hopefully won’t buy a product they don’t need.

1. What can be inferred from the three studies?
A.Social media greatly influences consumer behavior.
B.Ads for food are more popular than other types of ads.
C.People using social media choose more useful products.
D.Memorizing numbers has little effect on buying intentions.
2. What does the underlined part “cognitive overload”   in Paragraph 3 mean?
A.New ideas come into mind quickly.
B.One’s attention can be easily directed.
C.One shows little interest in communication.
D.The brain has too much information to process.
3. What does the researchers’ further study present?
A.Social media is a valuable advertising tool.
B.Product knowledge reduces the outside influence on buying.
C.Consumers with health concerns are careful about shopping.
D.People with a high quality of life hardly buy unnecessary things.
4. What can be the best title for the text?
A.Focus on yourself: you can make good choices
B.Click on more ads to choose the most cost-effective goods
C.Keep up with the times to improve your shopping experience
D.Buy without thinking: you are being influenced by social media

【推荐1】Yawning is something we all do—maybe because we’re bored carrying out tedious tasks or because we’re tired. Sometimes, just seeing other people yawn can set you off. But is this biological function really contagious, and why do we do it in the first place?

Many of us think we open our mouths when we yawn to take in more oxygen, but in fact it appears there is no clear biological reason. A new research suggests it might be because yawning cools the brain down and prevents it from overheating, much like the fan in your laptop. This might be why we’re more likely to feel drowsy and yawn in warm temperatures.

What is clear is that we yawn more when we’re exhausted and ready for a nap, and we can’t control when we do it—once we start, there’s no stopping us! But it’s also true that yawning is a very contagious behaviour. John Drury, a researcher from Sussex University, told the BBC that “dogs yawn when their owners yawn. Animals yawn to each other. It happens whether you want to or not.”

His research into this cognitive behaviour found that there is a connection with our social group and how close we are to the people in it. If we identify with the person who exhibits the behaviour, we are likely to copy it too.

Other researches by the University of Nottingham in 2017 found similar results. They asked volunteers to watch other people yawn. They found their ability to resist yawning when others around them yawned was limited. And the urge to yawn was increased when people were told they couldn’t. They also found, when using electrical stimulation(刺激), that they were able to increase people’s desire to yawn. These findings, they say, could be useful because it could help treat other conditions like Tourette’s, which involve the same area of the brain.

1. According to the new research, why are we more likely to yawn in warm temperatures?
A.Because we need to breathe more oxygen.
B.Because we are more likely to feel tired.
C.Because we need to make the brain cooler.
D.Because we are more likely to feel bored.
2. What does the underlined word “contagious” probably mean?
A.Powerful.B.Infectious.C.Similar.D.Influential.
3. What will happen when people are told not to yawn?
A.They will have stronger desire to yawn.
B.They will immediately stop yawning.
C.They will yawn less than before.
D.They will yawn more lightly.
4. Where is this text most likely from?
A.A novel.B.A diary.C.A magazine.D.A handbook.

【推荐2】The argument that human-caused carbon emissions(排放) are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around the rumor mill for years. And while it seems to be reasonable, the science just doesn't back it up.

According to the US Geological Survey (USGS), the world's volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes compose less than one percent of those generated by today's human activities.

Another indication that human emissions surpass those of volcanoes is the fact that atmospheric CO2 levels, as measured by sampling stations around the world, have gone up consistently year after year regardless of whether or not there have been major volcanic eruptions in specific years. “If it were true that individual volcanic eruptions dominated human emissions and were causing the rise in carbon dioxide concentrations, then these carbon dioxide records would be full of spikes —one for each eruption,” says Coby Beck, a journalist writing for online environmental news. “Instead, such records show a smooth and regular trend.”

Furthermore, some scientists believe that volcanic eruptions, like that of Mt.St. Helens in 1980 and Mt. Pinatubo in 1991, actually lead to short-term global cooling, not warming, as sulfur dioxide (SO2), ash and other particles in the air and stratosphere(平流层) reflect some solar energy instead of letting it into Earth's atmosphere. SO2, which converts to sulfuric acid aerosol, when it hits the stratosphere, can linger there for as long as seven years and can exercise a cooling effect long after a volcanic eruption has taken place.

Scientists tracking the effects of the major 1991 eruption of the Philippines’ Mt. Pinatubo found that the overall effect of the blast was to cool the surface of the Earth globally by some 0.5 degrees Celsius a year later, even though rising human greenhouse gas emissions and an El Nino event caused some surface warming during the 1991-1993 study period.

In an interesting twist on the issue, British researchers last year published an article in the peer reviewed scientific journal Nature showing how volcanic activity may be contributing to the melting of ice caps in Antarctica but not because of any emissions, natural or man-made. Instead, scientists Hugh Corr and David Vaughan of the British Antarctic Survey believe that volcanoes underneath Antarctica may be melting the continents ice sheets from below, just as warming air temperatures from human-induced emissions erode them from above.

1. According to Paragraph 1, some people argue that .
A.their opinion is supported by science.
B.volcanoes generate most of the greenhouse gases.
C.human activities are to blame for greenhouse gases.
D.carbon emissions produced by volcanoes are increasing.
2. What does the underlined word “spikes" in Paragraph 3 probably mean?
A.Sudden increases.B.Smooth trends.
C.Stable regularities.D.Sharp declines.
3. What do the scientists mentioned in this passage believe about volcanic eruptions?
A.They brought about global warming.
B.They actually partly cooled the surface of the Earth.
C.They melted the ice sheets in Antarctic from above.
D.They dominated human emissions in greenhouse effect.
4. The purpose of the passage is to .
A.compare the results of the studies.
B.contradict a view held by some people.
C.present new findings for greenhouse phenomenon.
D.report the effects of CO2, in greenhouse phenomenon.

文章大意:这是一篇说明文。本文主要介绍了什么是微距摄影,及这种摄影方式的操作方法。

【推荐3】Many people think that you need to travel great distances and go on expensive trips to create beautiful photos. If you consider macro photography, which is capturing (捕捉) tiny details, an entirely new world may open for you right in your own backyard. This is what I decided to do to challenge myself recently! I chose a relatively small area in my neighborhood to revisit over a couple of days, but the only rules I gave myself were not to photograph anything above the knees.

Using a 50 mm macro lens (微距镜头) on a traditional DSLR camera, I walked around looking for different opportunities. I also often use two extension (伸缩) tubes, which help me get ever closer to my subject matter and increase the magnification (放大率). In the evening light, the high contrast helps you see small things like jumping grasshoppers or other insects flying around, but during the day it can be more challenging. To find good subject matter, I like to crawl (爬) around and look at the world from a lizard or snake’s point of view. It adds significantly more drama, improves the image. It also has the power to transform a beautiful subject into a beautiful piece of art.

I really also pay attention to the background elements, not just the subject matter, especially with wildflowers. How in focus the background is, or how out of focus it is, can change an image. I like to shoot with a fully blurred (模糊的) background, called bokeh, though sometimes increasing depth of field and not having total blurriness can be beneficial to the composition, too.

You also don’t need a special camera set up to do this. Using a smartphone, you can easily use tools like portrait mode, to help blur the background. Some apps also allow for a greater level of control with depth of field and close-up photography. It’s less about the camera you use, and more all about how you use it!

1. What makes a splendid composition?
A.Taking an expensive trip.B.Capturing the details of life.
C.Shooting anything above the knees.D.Looking at a beautiful subject.
2. What is the second paragraph mainly about?
A.A traditional DSLR camera.B.The ways of macro shooting.
C.Shooting down at subjects.D.Insects flying around.
3. What does “this” refer to in the last paragraph?
A.backgroundB.portraitC.bokehD.camera
4. What would be the best title for this passage?
A.My NeighborhoodB.The Backyard
C.Crouching down YourselfD.Macro Photography
