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.jye.ai.
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 5，000 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（解釋）；
"There are，first，physiological（生理的） explanations，like more blood flow，and so more oxygen（氧氣） to the brain.Being physically active means there are more hormones（荷爾蒙） produced like endorphins（腦內(nèi)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.

1．According to a new curriculum standard（課程標準）for labor education in compulsory（強制的；義務(wù)的）education made by the government，students in primary and middle schools have at least one course every week on basic household skills such as cooking.

Some students talk about their experience about the cooking classes.1.Cooking is an important skill in life.Schools are supposed to teach knowledge to the students so that they can lead successful independent lives when they are out of school.Also，they can step into the world knowing how to make a living.

2．We all know the sun is important.It makes life on our planet possible.But how does the sun do that？It's the sun's energy.
Energy from the sun is called solar energy（太陽能） It comes in the form of light or heat.People have used solar energy for thousands of years.The sun's energy can be used to heat water and even food.If you own a magnifying glass，your parents have probably warned you not to leave it in the sun.Solar energy can actually make the magnifying glass burn objects underneath it causing a fire.This type of energy from the sun is called solar thermal（熱的）energy.
We can also turn the sun's light into electricity.This is done with solar panels（板）.Solar panels are made up of a material called silicon（硅）.The silicon is heated and formed into very thin wafers（晶片）.When the sunlight hits the solar panel，the electrons in the silicon move and flow through wires（電線）.Using this technology，we can run a calculator and even power cars in an easy way.
But what happens on cloudy days？The electrons in the silicon will stop moving，which means the electricity can't flow.But this doesn't mean that solar energy can only be used on sunny days.People can use the batteries（電池）which are attached to（附著于）solar panels to store the electricity.So the stored electricity can be used to power cars at night or on cloudy days.
Did you know that solar energy is not as expensive as it used to be？In fact，in the last few years.jye.ai panels have become much more affordable for people to use.Since the sun gives off more energy in one second than people have used，imagine what we could do if we used the sun's energy to power our planet.We all know the sun is important.Its energy makes life on our planet（1） .Energy from the sun is called solar energy.It comes in the form of light or heat.People have（2）solar energy for thousands of years.The sun's energy can be used to heat water and even food.This type of energy from the sun is called solar thermal energy.We can also turn the sun's light into（3）with solar panels.Using this technology，we can run a calculator and even power cars（4）.People can use the batteries which are attached to solar panels to store the electricity.So the stored electricity can be used to power cars at night or on（5）days.發(fā)布：2024/12/27 18:30:2組卷：2引用：3難度：0.5 -
