Dogs are man's best friends, and they may be the heart's best friends as well. 

A group of heart disease experts from the American Heart Association (AHA) reviewed research connecting heart health with owning a dog and found that owning a dog has a likely nexus with a lower risk of heart disease for those without a history of heart problems, and with greater survival rates among heart disease patients. 

The group, chaired by Dr. Glenn Levine, a professor of medicine at Baylor College of Medicine, released a scientific statement in favor of having a dog to lower the risk of heart disease by helping people to be more physically active as well as reduce blood pressure and minimize the effects of stress. Previous studies showed that the companionship and close relationship that owners build with their dogs can boost levels of anti-stress hormones (抗应激激素) that can increase resilience (适应力) and help people to cope with stressful situations. One of the studies found, for example, that those who adopted dogs enjoyed a drop in blood pressure, while another revealed that among 5, 200 adults, those who owned dogs were 54% more likely to get recommended levels of exercise and be active than non-dog owners. That trend is supported by other studies that found people who owned dogs were less likely to be overweight. 

According to a report of the Centers for Disease Control and Prevention( CDC), dogs aren't a panacea (灵丹妙药) against heart disease, and it's likely that taking care of them requires their owners to get more exercise, which can reduce stress, weight and blood pressure and thus benefit the heart. "If someone adopts a pet, but still sits on the couch and smokes and eats whatever he wants and doesn't control his blood pressure, Levine told the Neto York Times, "that's not a wise strategy to decrease the risk". 

(1) What does the underlined word "nexus" in paragraph 2 probably mean? A. Comparison. B. Similarity. C. Combination. D. Link.
(2) What can we learn from paragraph 3? A. Stress is the cause of heart attack. B. People raising pets can be slimmer. C. Doge' companion holds back hormone functions. D. Anti-stress hormone levels are low in dog owners.
(3) Which statement might CDC support? A. Dog owners work out more by walking the dog. B. Dogs can be trained to detect high blood pressure. C. Dogs can prevent owners from smoking on the couch. D. Dog owners attach importance to monitoring heart health.
(4) What does the passage mainly talk about? A. How dogs promote owners' mental health. B. Raising dogs can help reduce heart attack. C. What are the advantages of raising dogs. D. Having a dog may lower heart disease risk.

Humans are very social creatures. In addition to verbal(语言的) communication, we also use our bodies to help us better express our thoughts and feelings. This non-verbal communication is known as body language.

Body language includes things like facial expressions, eye contact and posture(姿势). It actually developed as a form of communication before humans could speak or write. We can tell a lot about what a person is thinking or feeling just by looking at them.

In fact, body language is so common that you may not even realize that you are communicating many messages to others every day without even using words. For example, you might move your head from side to side to express the word "no" instead of actually saying the word. Or, you might give a "thumbs(拇指) up" to show that you like or agree with something.

But now that we are spending more time online, we may not have as many in-person interactions as before. Because of this, our means of non-verbal communication has changed, but is still an important way to express our thoughts.

Our "digital body language" is becoming increasingly important as we change how we communicate. Instead of using voice messages, we can video chat with our friends to show them our smiling face. Another way to express our emotions digitally is through emojis(表情符号). When we are communicating online, we are only revealing the content and leaving out tones and facial expressions. That's when emojis can help in communication.

Whether using video chat to show our expression or sending an emoji, don't forget the importance of digital body language and non-verbal communication.

(1) What does the author mean by saying "Humans are very social creatures"? A. Humans like living in groups. B. Humans need to communicate. C. Humans depend on each other. D. Humans differ from other beings.
(2) Why are the two examples mentioned in Paragraph 3? A. To explain how to express no.    B. To prove how much one likes something. C. To demonstrate how to communicate messages.    D. To show how much we underestimate body language.
(3) What makes digital body language more and more important? A. The way of communication. B. The voice messages we use. C. The time we spend online. D. The invention of emojis.
(4) How can emojis help in communication? A. By revealing the content. B. By helping us video chat. C. By expressing our emotions. D. By leaving out facial expressions.

Nanako Hama was holding a light envelop. When she tore it open with care, locks of hair emerged. Many strangers send Hama locks of their hair, hoping to recycle it.

People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change. But hair possesses useful qualities that it's a shame to simply throw it away. That's why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks in the ocean.

Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mat, which are then used to clean up the floating oil. "Hair is particularly well-suited for this," says MoT co-founder Lisa Gautier. "That's because its rough sort of outer layer lets oil stick to it." MoT's mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.

In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair—significantly more than polypropylene (聚丙烯),a type of plastic that's typically used to clean up floating oil. Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氮), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.

"It's just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes—for oil and soil," Hama says.

(1) How does the author introduce the topic? A. By presenting a scene. B. By detailing the background. C. By describing the usage of hair. D. By praising an environmentalist.
(2) What can the mat made of human hair do? A. Improve soil. B. Prevent oil leaks. C. Take in harmful gas. D. Clear the sea of oil.
(3) Which qualities of hair contribute to its innovative use? A. Its color and strength. B. Its length and amount. C. Its weight and flexibility. D. Its structure and component.
(4) Which best describes the future of hair waste as fertilizer? A. Uncertain. B. Promising. C. Doubtful. D. Worrying.
