The scent of coffee appears to enhance performance in math
Drinking coffee has benefits. ______ the physical improvement, coffee may reduce our risk of heart disease. Coffee may even help us live longer. Now, research also reveals that the scent（气味）of coffee may help people perform better on the analytical portion of the Graduate Management Aptitude Test, or GMAT, a computer adaptive test ______ by many business schools.
The work, led by famous professor Adriana Madzharov, not only ______ the hidden force of scent and the cognitive（认知）improvement it may provide on analytical tasks, but also expectation that students will perform better on those tasks. Madzharov, with his colleagues, recently published their findings.
“It’s not just that the coffee-like scent helped people perform better on analytical tasks, which was already ______,” says Madzharov. “But they also thought they would do better, and we demonstraded that this expectation was at least partly ______ their improved performance.” ________, smelling a coffee - like scent, which has no caffeine in it, has an effect similar to that of drinking coffee, suggesting a placebo（安慰剂）effect of coffee scent.
Madzharov’s team tested 100 undergraduate business students, divided into two groups, with GMAT algebra questions. One group took the test in the ______ of a coffee - like scent, while a control group took the same test - but in an unscented room. They found that the group in the coffee-smelling room scored significantly higher on the test.
Madzharov’s team wanted to know more. Could the first group’s performance in quick thinking be explained, in part, by an expectation that a coffee scent would increase ______ and consequently improve performance?
The team designed a follow-up survey, conducted among more than 200 new participants, quizzing them on ______ about various scents and their effects on human performance. Participants believed that they would feel more alert and energetic in the presence of a coffee scent, in contrast with a flower scent or no scent; and that ______ to coffee scent would increase their performance on mental tasks. The results suggest that ______ about performance can be explained by beliefs that coffee scent alone makes people more alert and energetic.
Madzharov is now looking to explore whether coffee-like scents can have a(n) ______ placebo effect on other types of performance, such as verbal reasoning. She also says that the finding - that coffee - like scent acts as a placebo for analytical reasoning performance - has many practical ______, including several for business.
“Sense of smelling is one of our most powerful senses,” says Madzharov. “Employers, architects, building developers, retail space managers and others, can use scents to help ______ employees’ or occupants’ experience with their environment. It’s an area of great interest and ______.”

People generally see themselves through achievements. In doing that, they end up caring more about their image than the reality of who they actually are. Rather than their work doing the talking, they end up defining themselves by external markers that they hope will earn them respect.
The problem with this is that it encourages both themselves and other people to judge their worth based on some relatively unimportant measure. For example, one day, their educational diploma may overshadow what they actually learned. Therefore, a better way to know a person, I think, is to ask a different set of questions: What motivates them? What makes them ache? What do they long for?
It’s in this spirit that I want to publicly share my values. They are the compass(罗盘) that guides my life. The kindest and most sincere thing I can do is to see, recognize, and understand another person before I make judgments. From there, I can learn to treat others appropriately, depending on the context, learning from my mistakes with time and experience. It’s just a reminder that life is hard for all of us, while at the same time accepting that it’s important we are all also held accountable for our actions.
I have learned that we are all deeply self-interested. I hope to be self-aware enough to check out of the power and status games. That means I’m not competing with anyone for a shiny object; I’d rather compete with myself. It’s about becoming so uniquely different that it would be an insult for me to measure myself against someone else. I believe if I do the work to be internally free from the pull of the power and status games, then I can add value to others bused on my unique knowledge and experience.
If this resonates with(与...共鸣) you, I invite you to join me on this journey in understanding and relating to this complex world. It’s a wonderful mystery, and I think together we can better define it -- not just personally, but also collectively.

A.The external markers are better ways to know a person.
B.People generally judge others’ worth by what they have achieved.
C.The author is someone who is keen on power games.
D.Learning from mistakes is the first step of treating others kindly.
2.What does the underlined word “overshadow” probably mean?
A.be relatively similar to B.cause something to be stronger than
C.make something less important D.block off light from something
3.What of the following might the author agree with?
A.Life is hard, so we shouldn’t criticize others when they are not responsible.
B.One should overcome self-interest in order to judge others objectively.
C.Everyone is unique, so showing off uniqueness is an insult to others.
D.One should see and understand another person using a real compass.

Getting active in midlife could be as good for you as starting young when it comes to reducing the risk of an early death, researchers have suggested. But experts say the study also shows that the benefits fade once exercise declines.
“If you maintain an active lifestyle or participate in some sort of exercise from youth to middle age, you can reduce your risk for dying,” said Dr. Pedro Saint-Maurice, the lead author of the research. “If you are not active and you get to your 40s - 50s and you decide to become active, you can still enjoy a lot of those benefits.”
The study was based on data from more than 300,000 Americans aged 50 - 71 who undertook a questionnaire(问卷) in the late-1990s. They were asked to recall the extent of their moderate to vigorous leisure exercise at different stages of their life. Researchers then used national records to track who died in the years up to the end of 2016. After taking into account factors including age, sex, smoking and diet, the team found that those who were exercising into middle age had a lower risk of death than those who had never carried out any leisure exercise. However, when the team looked at different patterns in the way people were active over their life, it found a surprise.
Men and women who started exercising at the age of 40 - 50 reduced their risk of death from any cause by about 35%. The benefit was similar to that seen for people who reached and maintained similar activity from their teens or 20s onwards.
However, the study found that the protective effect of exercise did not last forever. People whose levels of leisure exercise decreased by middle age had no difference in the risk of an early death to those who had always been couch potatoes. “If you have been active and you slowly decrease your exercise participation as you age, you lose a lot of the benefits that we know are associated with exercise,” Saint - Maurice said.
But the study has limitations, including that it is based on individuals recalling how active they were many years before. What’s more, the research looked only at death records, not other aspects of health such as levels of sickness and disease. Nonetheless, he said, the message was positive. “This adds to the growing body of evidence about the importance of physical activity and exercise across he life course, and indicates that it is never too late to start.”
1.Which of the following is TRUE about the study?
A.The study took about two decades to complete.
B.The study involved around 30,000 elderly Americans.
C.Questionnaires and interviews were the sources of data.
D.The participants in the study took regular physical exercise.
2.According to the passage, what does “a surprise” (Para.3) refer to?
A.The earlier you exercise, the greater your health benefits will be.
B.Participating in exercise from youth to middle age benefits one’s health greatly.
C.The benefit of getting active in midlife is similar to that of starting young.
D.The benefits of exercising in midlife will decline once you stop exercising.
3.It can be inferred from the passage that _________.
A.an active lifestyle will not necessarily bring positive health benefits.
B.participants’ memories may affect the reliability of the study result
C.people exercising from their teens can maintain health forever
D.women benefit more from vigorous exercise than men do
4.Which of the following might be the best title of the passage?
A.Exercise has its limitations, studies show
B.Getting active when young, experts suggest
C.Health benefits fade with age, doctors warn
D.Never too old to start, researchers say

Ecotourism can put wild animals at risk
Ecotourism has become increasingly popular in recent years. 1. There travelers visit natural environments to fund conservation efforts or promote local economies.
Now, scientists have analyzed more than 100 research studies on how ecotourism affects wild animals. They find the presence of humans changes the way animals behave, and those changes may put them at risk. Therefore, they concluded that such trips can be harmful to the animals.
When animals interact in seemingly kind ways with humans, they may let down their guard. 2.. If this transfers to their interactions with predators（捕食者）, they are more likely to be injured or killed.
The presence of humans can also discourage natural predators. It creates a kind of safe place for smaller animals that may make them bolder. For example, in Grand Teton National Park, elk and pronghorns in areas with more tourists are less alert and spend more time eating.
3. “If animals become accustomed to tourists and if tourism practices enhance this taming, we might create unintended consequences - affecting the behavior or population of a species and influencing the species’ function in its community,” the researchers write.
Ecotourism has effects similar to those of animal domestication and urbanization. Research has shown that domesticated silver foxes become more obedient and less fearful. Fox squirrels and birds that live in urbanized areas are slower to flee from danger. 4.
Scientists hope the new analysis will encourage more research into the interactions between people and wildlife. It is essential to develop further understanding of how various species in various situations respond to human interaction and under what conditions human exposure may place them at risk.
A.As animals learn to relax in the presence of humans, they may become bolder in other situations.
B.This massive amount of ecotourism can be one of the drivers of rapid environmental change.
C.The phenomena result from evolutionary changes, but also from regular interactions with humans.
D.Do not import or release living animals or plants into the wild that could harm native species.
E.In many cases it involves close interaction with wildlife.
F.Interacting with people can cause great change in the characteristics of various species over time.

High level of deforestation continues
We are all aware of the threats our planet is facing. Experts agree that it’s mainly us humans who are responsible for the destruction of the environment. One of the most destructive activities we are carrying out is cutting down forests - deforestation. This is done for many reasons, such as providing wood for fuel, making land available for housing or for crating space for more cattle to graze(吃草) on. This has been most noticeable in Brazil, which is home to the world’s largest rainforest. Deforestation there has hit its highest rate in a decade, according to official data. Over the course of a year, an area about five times the size of London has been destroyed.
The amount of deforestation in the Amazon and in other tropical(热带的) regions has actually seen a decline but the figures are still large. Global Forest Watch say that in 2018, an area equivalent to 30 football fields were cut down every minute. Frances Seymour from the World Resources Institute says that “If you look back over the last 18 years, it is clear that the overall trend is still upwards. We are nowhere near winning this battle.”
What’s special about places like the Amazon is that they are primary forests which exist in their original condition with some species of trees dating back thousands of years. This habitat is home to unique and rare animals and is critical for sustaining biodiversity(生物多样性). The BBC’s environment correspondent, Matt McGrath, says “These old forests really matter as stores of carbon dioxide, which is way the loss of 3.6 million hectares in 2018 is concerning.”
Brazil has taken some steps to try and decrease deforestation by introducing government policies including fines for breaking land use regulations and illegal logging. And International campaigns to stop the trade of soy and beef farmed on deforested parts of the Amazon have also had a significant impact.
