Children today spend less time outdoors than ever before and it may be harmful not only to their physical health, but also to their cognitive (認(rèn)知的) development.

A year-long study, recently published in the Sciences, found that elementary school children who were exposed to more green space within or directly outside their school showed improved learning and memory. The findings reinforce (加強(qiáng)) that of a recent six-year study on 905 Massachusetts public elementary schools, which found that students in schools that had more “greenness” in their surroundings reported higher scores on standardized testing in English and math. “There is an expanding body of scientific evidence linking the human experience in the natural world to better physical and mental health and improved cognitive abilities,” journalist Richard Louv, co-founder of the Children & Nature Network, said in an email to The Huffington Post. “An increasing number of homeschoolers, nature preschools, independent primary and secondary schools, and forward-thinking public schools are incorporating (并入) nature experience into learning.”

The new study was conducted on more than 2,500 children in second, third and fourth grade at 36 primary schools in Barcelona, Spain. Researchers found that the students who attended schools with more green space showed a 5 percent improvement in the short-term memory that’s critical for reasoning, learning and comprehension. But their inattentiveness decreased slightly.

Spending time outside could have a number of benefits for children beyond improved memory and attention. Another recent study found that adventurous outdoor play such as climbing, rough and tumble (翻筋斗) play, and exploring alone improves children’s physical health while also help them develop creativity and social skills greatly.

Some schools are starting to take notice, creating more space for children to enjoy being in nature, including community gardens, outdoor playgrounds and small parks.

A. The cognitive abilities of children today decreased.

B. The findings of another six-year study were incorrect.

C. Being exposed to nature was beneficial to the learning of pupils.

D. Students had higher scores on testing in English and math than before.

2.According to the passage, what can we know about Richard Louv?

It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.

Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.

This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.

The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.

The villagers decided that they couldn’t just wait to see the crops failing and the children have to use the money earned to buy pesticides(殺蟲(chóng)劑) and medicines. Soon there was no money left.

Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job—eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.

1.From paragraph 1 we learn that the villagers __________.

A. worked very hard for centuries

B. were poor but somewhat content (滿(mǎn)足的)

C. dreamed of having a better life

D. lived a different life from their forefathers

2.Why did the villagers agree to sell frogs ?

A. The frogs were easy money.

B. They needed money to buy medicine.

C. They wanted to please the visitors.

D. The frogs made too much noise.

3.What might be the cause of the children’s sickness?

A. The crops didn't do well.

B. There were too many insects.

C.The visitors brought in diseases.

D. The pesticides were overused.

4.What can we infer from the last sentence of the text ?

A. Happiness comes from peaceful life in the country.

B. Health is more important than money.

C. The harmony between man and nature is important

D. good old day will never be forgotten
