Scientists have developed a new surgical glue that could transform emergency treatments by sealing up critical wounds in the skin or the organs, without the need for staples or sutures(釘合或縫合).

It’s called MeTro. It was developed by researchers from both Harvard Medical School and the University of Sydney, led by Nasim Annabi, an assistant professor of chemical 【1】. The glue is made from a modified(改良的)human protein that responds to UV light, allowing the application and drying of the gel-like substance in just a minute.

According to the international team of researchers behind the glue, it could quite literally be a lifesaver, sealing up wounds in 60 seconds without stopping the natural 【2】 and relaxing of the organ or the skin it’s applied to. Wounds 【3】 with MeTro can heal up in half the time compared with stitches or staples, the researchers claim, and if surgery is required then MeTro can simplify that 【4】 too. It's also one of several ways researchers are exploring to engineer our body's own natural substances to help repair it when needed.

The 【5】 applications are powerful – from treating serious 【6】 wounds at emergency sites such as following car accidents and in war zones, as well as improving hospital surgeries.

MeTro is simple to apply, can be easily stored, and works closely with natural 【7】 to heal a wound. What’s more, it degrades without leaving any kind of poisonous leftovers in the body.

For now the trials are 【8】 to animal models. But human trials are in the works, and the results to date are incredibly 【9】. If the MeTro can be further developed into a 【10】 product, it could become an essential part of a first responder’s toolkit.

【題目】 It is no secret that physical activity is necessary to a person’s well-being. Because children are continuously developing physically and emotionally, they are especially affected by the benefits of activity. Former First Lady Michelle Obama’s Let’s Move initiative reports that nearly one-third of US children are overweight or obese, and that “schools are a key setting for kids to get their 60 minutes of play with moderate activity, given the significant portion(部分) of time they spend there.”

Physical education programs in schools directly benefit students’ physical health. Regular exercise promotes muscles and bone development. In addition to participating in physical activity, students in P.E. learn the fundamentals of a healthful lifestyle, the building blocks upon which they can develop into healthy, knowledgeable adults.

Though the lack of attention on P.E. is often justified as an opportunity to spend more time in the classroom, studies show that physical activity contributes to improved academic performance. Regular activity during the school day is strongly associated with higher concentration levels. A statewide policy in North Carolina requires that children from kindergarten to eighth grade participate in 30 minutes of physical activity each day.

Activities in P.E. help children develop healthful social interactions. From a young age, children learn cooperation through group activities and form a positive sense of identity as part of a team. Such group activities are continually important as children grow older. The International Platform on Sport and Development states that sport has been used as a practical tool to engage young people in their communities through volunteering, resulting in higher levels of leadership and community engagement among young people.

The benefits of P.E. to a child’s mental health are both complex and comprehensive. Improved physical health, academics and social interactions all contribute to good mental health. Physical activity sets the stage for a good night’s sleep, provides more energy to participate in hobbies and interact with others.

【1】The first paragraph implies that ________.

A.children are becoming much lazier nowadays

B.some schools have forbidden physical activity

C.most parents are dissatisfied with school education

D.schools must pay more attention to physical education

【2】Physical education is ignored in a way because ________.

A.children dislike taking physical activity

B.schools are worried about children’s safety

C.students should have more time for study

D.less sporting equipment is available to school children

【3】Which is NOT a benefit of P.E.classes?

A.They assure you of a successful future.B.They keep your mind in a good state.

C.They help you focus on your studies.D.They do good to your social skills.

【4】What is the author’s possible attitude towards the policy in North Carolina?

A.Sceptical.B.Favorable.

C.Ambiguous.D.Objective.
