A recent research shows that physical activity(体育活动) may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P.E. class.
Researchers go over the results of fourteen studies. Twelve were from the United States, one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen.
Thomas Singh, one of the researchers, says the studies showed a relationship between physical activity and scores on subjects such as math, English and reading. Ms. Singh offers some possible explanations (解释):
“ There are, first, physiological (生理的) explanations, like more blood flow, and so more oxygen (氧气) to the brain. Being physically active means there are more hormones（ 荷尔蒙） produced like endorphins ( 脑内啡). And endorphins make your stress level lower and your mood improved, which means you will perform better in class. Also, students who take part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them know what they should do.
All in all, the finding tells us that physically active kids are more likely to do better in school. Ms. Singh says schools should consider the finding before they cut physical education programs. What led the researchers to do the studies?
| A．Schools’cutting physical activity. |
| B．Their interest in physical activity. |
| C．The tests including about 55,000 children. |
| D．Kids’unsatisfying schooling performance. |
How many countries took part in the studies?
| A．14. | B．12 | C．2. | D．3. |
Which of the following is NOT one of the advantages of physical activity according to the passage?
| A．Getting more blood flow. |
| B．Better classroom behavior. |
| C．Feeling relaxed and refreshed. |
| D．Greater ability to organize activities. |

A crow(乌鸦) is about twenty inches(英寸) long and black all over. Crows are dirty birds because they live on bad food. Crows eat a lot of waste food. In this way they are more useful to us than any birds. They clean up the dirty things in our streets. Crows are always hungry. They look for food all day, and in the evening you can see them in large numbers flying back to their nests(巢) in the trees. They sleep there at night.
Crows are much noisier than other birds. Very often a large number of crows will get together on one house and talk. Sometimes they talk together, and sometimes they do it by turns(轮流) like human beings(人类). It is easy to tell(判断) from crow’s sound if they are pleased or angry. Perhaps crows talk a lot because they are friendly birds. A pair of crows will live together all their lives, and if one of them dies, the other one becomes very sad and quiet for the rest of its life and some time later it dies too.Crows “live on bad food” means “ _________ ”.

If we find a bird nest (巢), we will have a good place of watching and knowing about birds. Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we'd better hide ourselves in a close place to the nest, and it's better to use binoculars
But how do we make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these:
a) Each nest must have six boards (木板) for its cover and floor, for its left and right sides, and for its front and back sides. Don't make the boards too slippery (滑的).
b) Dig a small hole in the front of the nest as a "door". The "door" is big enough so birds can fly in or out easily.
c) Make sure the rainwater can't go into the nest.
d) One piece of the board should be easy to open.
e) Don't forget to colour the nest.We need ______ near a bird nest if we want to watch and know about birds.
| A．a good place | B．some trees |
| C．to sit on eggs | D．to make a bird net |
When we’re watching birds, we have to ______.
| A．look after the birds more often |
| B．use the binoculars to catch the birds |

We should leave a hole in the front of the nest so that ______ easily.

According to the text, we can make a bird nest like Picture ______ with the boards.
Long long ago, a donkey(驴) fell into a well(井). The animal cried for hours as the farmer tried to think out what to do. Finally, the farmer thought the animal was too old and the well needed to be covered up anyway, so he decided not to save the donkey.
The farmer invited his neighbours to help him. They began to shovel(铲) dirt into the well. The donkey cried harder. But a few minutes later, he became quiet. The farmer looked into the well, and was surprised by what he saw.
While every shovelful of dirt hit his back, the donkey would shake it off and take a step on the new layer of dirt. As the farmer’s neighbours continued to shovel dirt on top of the animal, the donkey would shake it off and take another step up. Soon the donkey stepped up out of the well and ran away, to the surprise of all the neighbours.
The lesson we get from this story is that if life shovels some dirt on us, we must get out the well and not let it cover us. We must learn to shake it off and take a step up. Each of our troubles is a stepping-stone(踏脚石). We can get out of the deepest well by never giving up!The farmer is ________.
| A．careless |
| B．kind to the donkey |
| C．ready to give up the donkey |
| D．friendly |

If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.The main subject talked about in this passage is ________.
| A．science on learning a second language |
| B．man’s ability of learning a second language |

The underlined word “bilingual” probably means _______.
| A．a researcher on language learning |
| B．a second language learner |
| C．an active language learner |
| D．a person who can speak two languages |
We may know from the scientific findings that ________.
| A．the earlier you start to learn a second language, the higher the grey matter density is |
| B．there is no difference between a later second language learner and one who doesn’t know a second language |
| C．the experience of learning a second language has bad effect on people’s brain |
| D．the ability of learning a second language is changing all the time |
In the last two paragraphs, the author wants to tell us that _________.
| A．learning a second language is the same as studying maths |
| B．early learning of a second language helps you a great deal in studying other subjects |
| C．Italian is the best choice for you as a second language |
| D．you’d better choose the ages between 2 and 34 to learn a second language |
