Ⅰ. 户外时间
是时候进行户外活动了！本不想进行户外游学的David查阅了资料，了解了保证户外时间的重要性。
Today，young people spend about six hours a day in front of a TV or a computer and less than four minutes playing outdoors. It is not healthy for people's mind and body when they spend more time on technology but not outdoors.
Some health experts call green time “Vitamin G”. Kids who don't get outdoors much seem to have trouble in school. Doctors believe that is because being outdoors excites the mind more than sitting around indoors. Even those who usually spend a lot of time outdoors find a difference when they don't get green time. Madelyne P.，14，says，“I feel more tired when I don't get outdoors.”
Researchers believe the advantages of green time come from the outdoor activities in the free time，such as jogging or boating. Exercise makes something special in brain that can improve learning，mood(情绪)，and sleep. It also develops learning by increasing(增强) connections between nerve cells(神经细胞) that are important in learning and memory. Some schools hold classes outside for these reasons. Student Hannah Smith，18，says she believes the outdoors helps her think and gets her to learn carefully. Learning in a forest sparked her interest in art and photography too.
Even doctors are helping give their patients some Vitamin G. Miller writes “park prescriptions (处方)” for her patients，because she says，“Being outdoors is good for health.” She finds that when she gives patients park prescriptions，they seem to continue with them.
Getting outdoors can be simple，just like calling together your family for a picnic lunch. All it takes is five minutes or more of green time：Get outside，and get your Vitamin G!
1. Which of the following activities is NOT an example of “Vitamin G”?
A. Watching TV.
B. Going hiking.
C. Taking a boat tour.
D. Having a picnic.
2. Researchers and doctors may both agree that
A. kids without green time are likely to have trouble in school
B. people who get outdoors a lot may feel the same way indoors
C. exercise improves learning by increasing the number of cells
D. Vitamin G may help patients get into the habit of being outdoors
3. What does the passage mainly talk about?
A. The finding of a new vitamin.
B. The good parts of green time.
C. The influence(影响) of technology.
D. A different way of learning.

### Ⅰ. 户外时间
是时候进行户外活动了！本不想进行户外游学的大卫查阅了资料，了解了保证户外时间的重要性。
如今，年轻人每天大约花6个小时看电视或玩电脑，而在户外玩耍的时间不到4分钟。当人们把更多时间花在科技产品上而不是户外活动上时，这对他们的身心是不健康的。
一些健康专家把户外时间称为“维生素G”。不常进行户外活动的孩子在学校似乎会遇到麻烦。医生认为这是因为户外活动比待在室内更能激发思维。即使是那些通常花很多时间在户外的人，当他们没有户外时间时也会发现不同。14岁的玛德琳·P说：“当我不进行户外活动时，我会觉得更累。”
研究人员认为，户外时间的好处来自空闲时间的户外活动，比如慢跑或划船。运动能使大脑产生一种特殊的物质，这种物质可以改善学习、情绪和睡眠。它还通过增强神经细胞之间的联系来促进学习，而神经细胞在学习和记忆中很重要。出于这些原因，一些学校在户外上课。18岁的学生汉娜·史密斯说，她相信户外活动有助于她思考，让她认真学习。在森林里学习也激发了她对艺术和摄影的兴趣。
甚至医生也在帮助他们的病人获得一些“维生素G”。米勒为她的病人开“公园处方”，因为她说：“户外活动对健康有益。”她发现，当她给病人开公园处方时，他们似乎会坚持下去。
进行户外活动可以很简单，就像召集你的家人一起吃野餐午餐一样。只需要5分钟或更长时间的户外时间：到户外去，获取你的“维生素G”！
1. 以下哪项活动不是“维生素G”的例子？
A. 看电视。
B. 徒步旅行。
C. 乘船游览。
D. 野餐。
2. 研究人员和医生可能都同意________。
A. 没有户外时间的孩子在学校可能会遇到麻烦
B. 经常进行户外活动的人在室内可能会有同样的感觉
C. 运动通过增加细胞数量来改善学习
D. “维生素G”可能帮助病人养成户外活动的习惯
3. 这篇文章主要讲了什么？
A. 一种新维生素的发现。
B. 户外时间的好处。
C. 科技的影响。
D. 一种不同的学习方式。
