Working out can help teenagers boost their grades, a new study suggests. Adolescents who routinely engaged in moderate to vigorous（剧烈的）exercise showed long-term improvements in their academic performance, the British Journal of Sports Medicine study reported.
“Our study suggests that the effect of physical activity may be quite large,” John Reilly, a professor at the University of Strathclyde said. The researchers looked at a sample of about 5000 children who were involved in a long-term study that tracks children born in the UK between 1991 and 1992. When children reached 11 years old, their daily physical activity levels were measured using an accelerometer（加速器）for three to seven days. The device, similar to a pedometer（计步器）tracking the number of steps taken, recorded the average time children exercised, which was 29 minutes a day for boys and 18 for girls.
“The actual levels of daily physical activity at age 11 were quite low,” Mr. Reilly noted. The children had their academic performance tested at ages 11 and 13 with compulsory national tests for students, and also at 15 or 16 with the General Certificate of Secondary Education (GCSE) exam. The tests assessed the children’s abilities in English, math and science subjects. The results showed that the more children participated in moderate to vigorous physical activity, the higher their test scores were at age 11 in all three subjects. For girls, science scores were most strongly linked to exercise.
When children were tested again at age 13, their academic scores were still linked to how much they had exercised when they were 11 years old. By the time the youngsters took the GCSE exam, each 17-minute-per‑day increase in physical activity for the boys was linked to an improvement in their scores. Every additional 12-minute increase a day in exercise for the girls was also linked to an increased score, especially in the science category.
The researchers have called for more studies to look at the possible academic benefits that could be derived if students exercised the recommended 60 minutes or more a day.

London has just signed to be the first National Park City. Sadiq Khan, mayor of London, along with several organizations and individuals, signed the London National Park City Charter(宪章) on Monday.
London is already extremely park-like. With a large number of urban parks and waterways and 8.4 million trees, it has a lower urban density (密度) than many other major cities. It is also home to 15,000 species.
The charter aims to improve the lives and well-being of people and wildlife by improving the natural environment of the city. In practical terms, that means trying to reach the goal of turning 50% of the city into green space by 2050. That can be achieved by asking residents to change empty lots and yards into gardens, planting more trees throughout the city and even cutting holes in garden fences. Adding green roofs to existing buildings is also part of the plan,
One way to help achieve its goal is pairing development with conservation. London is expected to add some 2 million new residents to its current population by 2040, meaning it needs thousands and thousands of new homes. Home developers can play a role by surrounding new homes with parks or nature reserves.
"Inspired by the aims and values of the world’s national parks, the London National Park City is fundamentally about making life better in the capital through both small everyday things and long-term strategic thinking." says Daniel Raven-Ellison, founder of the concept.
"It's about lifting our ambitions; going further to make the city greener, healthier and wilder; improving our mental health, cleaning our air; making the city richer in wildlife: freeing children to play and meet friends outdoors again; solving the climate crisis and bring more joy to the city." He added.
Timothy Beatley, an urban planner, says countless cities have already woken up to the idea that greening and improving natural connections make urban life much better. "The basic idea is that nature in cities is not optional but absolutely essential to a happy, healthy and meaningful life." He says.
1.What are mentioned in paragraphs 3 and 4 about the green move?
A.The conflicts caused by the charter.
B.Different voices about the move.
C.Specific ways to expand green space.
D.Challenges the move will run into.
2.The founder and the planner mentioned both hold a(an) ___________ attitude to the charter.
A.skeptical B.critical
C.reserved D.favorable
3.What can be a suitable title for the passage?
A.A green and meaningful life in London
B.London to be "National Park City"
C.Reasons for more green space in London
D.Green ways to make London park-like
