How Many Cups of Coffee per Day Are Too Many?

From cappuccinos to cold brew, coffee is a must-have to start the day for many people. 1. However, a new study suggests too much coffee can be harmful.

This is what a recent study shows. 2. A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won’t hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee.

Knowing the limits of what's good for us and what's not is necessary. 3. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure. 4.

Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful.

5. Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day.

A. Drink no more than six cups per day.

B. Over the limits and our health will pay for it.

C. Coffee is the most popular drink in the world.

D. But of course, don't forget to listen to our body.

E. The relation between them is quite complicated.

F. As we know, it is a key heart disease risk factor.

G. It sets you off on an energetic morning and prepares you for a busy day.

 

1.G 2.A 3.B 4.F 5.D 【解析】 这是一篇说明文。文章介绍的是一天喝多少咖啡算多。 1.由上文coffee is a must-have to start the day for many people.可知,咖啡对很多人来说是一天的开始,接着就该解释为什么喝咖啡是一天的开始,因为咖啡让你在充满活力的早晨精神焕发,为忙碌的一天做好准备。故选G。 2.由下文的But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found.可知,一天六杯或更多咖啡会增加心脏病的发病率,所以空白处的内容应是一天要少于六杯咖啡。故选A。 3.由上文Knowing the limits of what's good for us and what's not is necessary.可知,要知道对我们有益和哪些是不必要的限制。及下文About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention.可知,美国四分之一的死亡是心脏病所致,因此空白处要把这两个意思连起来,就应该是超过限制,健康就会付出代价。故选B。 4.由上文Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure.可知,心脏病是世界上死亡的主要原因。这也是为什么Elian要着手研究多少咖啡因会造成高血压的原因。咖啡因和死亡的联系是咖啡因是心脏病的诱发因素。故选F。 5.由下文Even though the research says five cups of coffee is permissible, each person should know his or her own limit.可知,即使研究者说五杯咖啡是允许的,但每个应该知道自己的极限。因此,要听从自己身体的声音。故选D。

    Our society is becoming increasingly overweight. 1. Similar to humans, overweight pets have a much higher risk of health problems. Dr. Katrina Warren shares her expert advice on the issues, causes and treatments for overweight pets.

Recent estimates suggest over a third of overweight pets are suffering from health problems. Diabetes (糖尿病) and diseases related to heart top the list of weight-related disease. To put it simply, weight issues occur when pets consume more kilojoules (千焦) than they use. Owners are a key part of the problem. 2.

3. Working out regularly helps keep pets in shape. As pets no longer need to hunt for their food, they typically enjoy a comfortable lifestyle, lazing around indoors, thus gaining weight easily. What’s more, food should always be adjusted to a pet’s energy requirements. 4. They assume the pet will control its own intake. So it’s easy to fall into the trap of feeding your pet whenever it begs for food.

Fortunately, there are plenty of diet and lifestyle changes to help your pets maintain a healthy weight. For example, pets will benefit from more exercise in their daily life, like eating food. Don’t put food in their bowls. 5. Meanwhile, you can also consult experts about guidance for a healthy diet.

Anyway, provide them with an appropriate diet and proper amounts of exercise, and you may have healthy pets.

A. They’re related to the diet.

B. So are our lovely friends — pets.

C. Another contributing factor is lack of exercise.

D. Try encouraging the pets to exercise step by step.

E. Yet many owners provide constant access to food.

F. They ultimately decide what and how much the pets eat.

G. Rather, spread some food around your house so your pets must find it.

    Almost 200 graduate students and postdoctoral ( 士后) researchers gathered April 21 for a career-development event at the annual meeting of the American Society for Biochemistry and Molecular Biology where they learned about varieties of scientific careers, participated in skill-building workshops and networked with peers and speakers. The entire event was full of useful information1.

Your career path is less like a ladder and more like a jungle gym.

We're all programmed to see our career path as a series of linear (直线型) steps up to a final goal undergraduate, graduate, post doctor, forever job — but this rarely happens.2.Don't be afraid to take a risk when opportunities present themselves if they will help you build your unique career.

Create a “skills toolbox" and use it.

The skills you develop as a trainee help you stand out in the job market. When you're in the lab, talk to your colleagues about their experiments. Challenge yourself to learn new techniques both in and out of your field. Work on developing critical thinking skills, which will help you however your career evolves.

And acquire skills outside the lab. Explore entrepreneurship, science writing and communication, policy, outreach, education, even art — whatever resonates with you. 3.

Communication skills are critical to success. Less jargon (行话),more passion.

Science is a language most people don't speak fluently. When communicating with diverse audiences, think of yourself as a translator. Eliminate jargon and create analogies (类推) to make your research accessible. Work on making your science story relevant to the audience, which may mean that you don't share every piece of data you have collected. Most importantly, practice.

Training courses like the ASBMB's Art of Science Communication are available to help you develop these skills.

4.

In professional interactions, be confident and remember that your skills and knowledge got you where you are today. Don't be frightened by people who question what you know, and don't let negative experiences diminish your self confidence.

Luck is what happens when preparation meets opportunity. You don't need to see the entire staircase to take the next step.

With these words in mind, explore your options, network and talk to people in fields that interest you. Don't know where to start? Start with videos under the heading "Career Paths” at asbmb.org and the career section of the ASBMB Today website. 5. . For the price of a cup of coffee, you can get started on the path to career success.

A. Don't be afraid of new challenges.

B. Work on believing that you belong in the room.

C. Below are five tips for career success that struck me.

D. This will help build you into a well-rounded candidate.

E. You may move sideways in your career or even take a step or two back before moving up the ladder again.

F. Once you find a job that interests you, identify people in the field and ask for informational interviews.

G. Imposter (冒名顶替者)syndrome is a reality for many people in the sciences, especially those from underrepresented groups.

What does it mean to be intelligent?

It seems that everyone goes to college now, whether or not they find themselves interested in studying something long term. Even though I know there are different ways to be intelligent, I struggle due to society’s influence, which maintains that intelligence is quantifiable (可量化的) and that academic intelligence is one and the only.

Where do IQ tests come into play when one considers intelligence? Do they fall closest to priority when considering this unquantifiable concept? Intelligence simply cannot be reduced to an IQ test, which are not effective. While designed to measure “intelligence,” all they measure are biological developments that can change as one grows. 1.

There are many factors that can indicate an intelligent being, such as academic intelligence, emotional intelligence, and worldly intelligence. For instance, if a student realizes that they haven’t studied appropriately for an exam, he or she would have the ability to acknowledge that, and then make revisions to his or her study habits accordingly. 2. Emotional intelligence is the intelligence that fosters self-awareness, self-reflection, and self-improvement.

3. We cannot function without forming relationships and communication. This proves that being aware of oneself and reflecting in order to further better communication skills is an evidence to intelligence. Where would you be if you were a terrible communicator, unaware, and unwilling to improve, but academically thriving?

Emotional intelligence is what surpasses (超越) those who are hard-headed. Those who maintain academic intelligence may still be a bit dull and unaware of themselves. 4.Even as a college student, there are certain skills such as teamwork and communication that require awareness and an open mind in order to further their growth.

5. Academia is not only pictured and taught unfairly, or even close to what intelligence is if you were to quantify it. If you want to strive for mental growth, and maintain self-awareness through self-reflection, you can apply that to any intelligence category.

A. All of life is communicatory.

B. Specifically, this is emotional intelligence.

C. Intelligence is determined by many factors.

D. Stubbornness is a barrier towards communication.

E. In fact, there are many with low IQ scores that are intelligent.

F. Some connections exist between intelligence and communication.

G. So there is academic intelligence, emotional intelligence, and worldly intelligence.
