A recent research shows that physical activity 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 : " There are, first, physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones( ) produced like endorphins ( ). 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.

These days there are lot of possibilities to be always connected to family and friends. Now that I have just moved lo France, this can be very convenient. 1 can ring my sister who lives in Los Angeles on Viber, or I can Skype my parents or friends back in England for a chat. However, sometimes the convenient and dependability of technology can be _ . Even the most out-going people need some "down time" to calm down on their own and get relaxed. This is something that I consider necessary and healthy. After all, you have to live with yourself for the rest of your life, so you'd better know how to enjoy your own company. It can be a good thing to have time to yourself to collect your thoughts and free your feelings. Today 1 went for a walk by myself around the lake and just dav-dreamed. It was so relaxing and enjoyable and helped me let go of my bad emotions. However, somehow it seems rude or perhaps makes people feel that you'reupset to sayto people:" I'm going to go and spend sometime by myself. " Andoften when we are spending time 'alone' , we are actually connected with a piece of electrical equipment. We try to make something into a Facebook or a Tweet to attract our friends, or we scroll (> through Facebook nosing into other people's lives orseeing what friends are up to. We judge ourselvesand other people by the photos they put online, so we can tell how much fun they are having compared to us. This is an age when we can get so much surface information about other people's lives, but being wrapped up in what other people are doing or always thinking about other people's recognition of us can be quite unhealthy. Perhaps these days forget about the simple pleasure of spending time just for us. Having said all that, I also think that spending too muchtime byyourself can separate you from others. I suppose it is important to find a good balance between spending valuable time by yourself and with other people. What does the writer think of being alone properly? A) It's the only way to get relaxed. B) It makes other people feel upset. C) It's necessary and healthy for people. D) It makes out-going people feel lonely.

Q: It is reported that in the near future robots and humans will probably work together to create jazz. A singing robot is being taught to create jazz with human being in a project. Antonio Chella from Italy is working with a Telenoid robot. To start with, the Telenoid will be trained to _ the movements and simple sounds made by a human singer, and then connect music with different human emotions. Previous robots had the ability to find common connections between things. But Chella suggests that a conscious robot should be able to go a step further and find new connections. The Telenoid is of this kind. "This work raises interesting questions about the connection between consciousness and music creating." says Philippe Pasquier, a musician needs a physical body. Pasquer argues that the robot musician is faced with a big challenge. "Its software has already been developed and it can imitate The Beatles, a famous band. However, what made The Beatles famous were not only their songs but their wonderful performance of the songs," he says. It is not clear how a robot would perform music a new way. But by imitating humans, the Telenoid robot could provide some useful information. What is important is that human musicians often listen to and compare music made by others for a long time before creating music of their own. So the Telenoid robot had better listen to more jazz music first. In Pasquier's opinion, the Telenoid robot _ A) will replace human musicians soon. B) may have trouble performing music. C) will become more popular than The Beatles. D) can find connections between things that humans cannot find
