According to a national study, in the summer of 2013, the long-term(长期的) warm weather in the UK has made the number of butterflies increase.

Around 46,000 volunteers(志愿者) took part in the year’s Big Butterfly Count(统计), and they found 830,000 butterflies.Volunteers were asked to make a record.They would record how many times they found one of 21 different kinds of butterflies.

Later, the scientists used the records to find out how many butterflies of different kinds were found across the country.Then, they compared the results to the year before.They found that there was a rise in the number of 15 kinds of butterflies, and some of them went up by 50% compared to recent years.They said the increase in butterfly numbers was a result of warm weather.

However, scientists also said that the number of butterflies was in decline(下降) as a whole, and that we might not see the same result the next year.

Richard Fox, who works for Butterfly Conservation, said, “UK butterflies are in long-term decline.Studies have been done since the 1970s.They show that UK butterflies have declined in type and number.”

He added, “We must halt the long-term decline of these beautiful creatures(生物).The only way is by stopping the damage that has been done to the butterflies’ habitats(栖息地) across the UK.”

You know that eating a sensible diet and getting plenty of exercise help make your body healthy and strong.But do you know that there are ways to make your brain healthier and smarter? Here are some steps toward a smarter brain.

Limit your TV viewing

(1) Never spend too much time on TV viewing, for it needs very little brain activities.Your brain will become weak just as your muscles do.If you do watch TV, choose something educational and meaningful.

Travel

Travelling to another country forces you to see and do things in a fresh way, bringing stimulation to the brain.

Learn a new language

Learning a new language involves different learning methods.Learning a language sharpens your brain and helps prevent memory problems that you may meet in later years.

Read often

As you read, take the time to look up people or places that aren’t familiar.Reading makes your vocabulary much larger if you always search for words and definitions that you don’t know.Each week, choose an animal, a bird or fish, and read everything you can about it.Stretch your brain as you become an expert on the subject.

Calculate (计算)when you shop

As you put things in your grocery cart, total everything in your head.See how close you get to the actual total.

Use your non-dominant(不占优势的)hand

If you are right-handed, use your left hand for everyday activities, or use your right hand if you are left-handed.Doing familiar things in a different way will make your brain create new neural (神经)networks.

Wechat(微信)

(2) Read messages from various people.They have different interests.And some say that learning to express yourself in just 100 words is a great brain challenge.

Have a try and do these every day.Little by little you can get into the habit of challenging your brain, and make your brain smarter!
