How do you feel about nature? After spending hours indoors, do you feel better when you visit your local park? Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada’s national parks is getting lower every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty—first century.
As a result, some doctors are studying the connection between nature and health: one example of this is the work of Dr Matilda in Sweden. The doctor gave people a maths test. During the test, their heart rates (心率) were fast. After the test, one group of people sat in a 3D—virtual—reality (虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people's in the other group.
The virtual touch with nature helped them feel more relaxed. Another good example of how nature is good for health comes from Canada. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks.
Because of studies like these, some countries and cities want nature to be part of people’s everyday life. In Dubai (迪拜), for example, there are plans for a new shopping mall with a large garden so shoppers can relax outside with trees, plants and water. In Switzerland, “forest schools” are popular. Schoolchildren study their subjects in the forests and do lots of exercise outside. And South Korea (韩国) is another good example: it has new forests near its cities and around 13 million people visit these forests every year. So after building cities for so long, perhaps it’s now time to start rebuilding nature.

本文是一篇说明文，主要介绍了大自然对人类的身体健康有益，一些国家和城市正在积极地采取措施，让大自然成为我们生活的一部分。
45.B【解析】主旨大意题。根据第一段“However, humans are spending more time inside and less time outside…Many doctors feel that this is a problem in the twenty—first century”可知，本段主要以加拿大、美国等国家人们的户外活动时间情况为例，介绍了如今人们的户外活动时间正在逐渐减少。故选B。
46.B【解析】细节理解题。根据“And in countries such as the USA, only 10% of teenagers spend time outside every day”可知，美国只有10%的青少年每天都在户外活动，故①—d；根据“In Dubai(迪拜), for example, there are plans for a new shopping mall with a large garden…”可知，迪拜的一座带有大花园的新的购物中心即将建成，故②—c；根据“In Switzerland, “forest schools” are popular. Schoolchildren study their subjects in the forests and do lots of exercise outside”可知，在瑞士，“森林学校”很受欢迎。小学生们在森林里学习他们的科目，在外面做大量的运动，故③—a；根据“And South Korea (韩国) is another good example: it has new forests near its cities and around 13 million people visit these forests every year”可知，在韩国，每年大约有1300万人参观城市附近的森林，故④—b。故选B。
47.C【解析】细节理解题。根据第三段“The virtual touch with nature helped them feel more relaxed. Another good example of how nature is good for health comes from Canada”可知，实验结果显示，自然能够帮助人们放松，并且让人们更健康。故选C。
48.D【解析】推理判断题。根据最后一段“some countries and cities want nature to be part of people’s everyday life…So after building cities for so long, perhaps it’s now time to start rebuilding nature”可知，在建设了这么长时间的城市之后，也许现在是时候开始重建自然了，这句话意味着“我们应该重建自然，让自然成为我们生活的一部分”。故选D。
