5.Some people are like homing pigeons:Drop them off anywhere,and they'll find their way around.Other people,though,can't tell when they're holding a map upside down.Are the directionally challenged just bad learners?
Not all of your navigational (導航的)skills are learned.Research shows that your sense of direction is innate.An innate ability is something you are born with.Your brain has special navigational neurons-head-direction cells,place cells,and grid cells (網格細胞)-and they help program your inside compass when you're just a baby.
In 2010,scientists carried out an experiment to study baby rats'neural activity in their brains.Although the rats were newborns,the researchers discovered that their head-direction cells (which help them recognize the direction they're facing) were fully grown and developed.The rats,it seemed,were born with a sense of direction.And they hadn't even opened their eyes yet!
Humans,of course,are not rats.But the hippocampus-the brain area we use for navigation-is similar in most mammals.If the rat's compass develops this way,then it's likely that a human's compass does,too.
If we're born with a sense of direction,then why are some people so good at getting lost?The scientists found that the two other cells-place and grid cells-developed within the first month.Place cells are thought to help us form a map in our mind,while grid cells help us navigate new and unfamiliar places.The two cells work together,and that's where the trouble might be.
People who took part in a 2013 study played a video game that required them to travel quickly between different places.Monitoring their brains,the scientists found that grid cells helped the gamers recognize where they were-even without landmarks.According to researcher Michael Kahana,differences in how grid cells work may help explain why some people have a better sense of direction than others.
32.What did the 2010 research find?A
A.Rats have a natural ability to recognize directions.
B.Rats'hippocampus is different from that of humans.
C.Rats usually find their way without opening their eyes.
D.Baby rats have as many head-direction cells as grown-ups.
33.What do we know about our navigational neurons?D
A.Place cells let us know how to read a map.
B.Grid cells help us reach the place we are going to.
C.They help us use a compass when we lose our way.
D.Place and grid cells grow later than head-direction cells.
34.Why are some people so good at getting lost?B
A.They can't remember landmarks.
B.Their grid cells can't work very well.
C.They are unfamiliar with new places.
D.Their ability to follow directions is poor.
35.What is the text mainly about?A
A.Human navigational skills.
B.The compass in rats'body.
C.Why grid cells are useful.
D.How homing pigeons work.

12.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) that of a recent six-year study on 905Massachusetts 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 2,500children in second,third and fourth grade at 36primary schools in Barcelona,Spain.Researchers found that the students who attended schools with more green space showed a 5percent 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.
32.What did the study lasting a year find?C
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.
33.According to the passage,what can we know about Richard Louv?B
A.He discourages students from getting close to nature to gain experience.
B.He is one of the founders of the Children & Nature Network.
C.He conducted the study on 905Massachusetts public elementary schools.
D.He often contributes articles to The Huffington Post.
