That's all. Thank you!

A teacher began his class by holding up a glass with some water in it.  He held it up for all to see, and asked the students, " How much do you think this glass weighs?"

"50 g!" "100 g!" "125 g!" the students answered.

        "I really don't know unless I weigh it," said the teacher, "but my question is what would happen if I held it up like this for a few minutes?"

" Nothing! " the students said.

"OK. What would happen if I held it up like this for an hour?" the teacher asked.

"Your arm would begin to ache," said one of the students.

"You're right.  Now, what would happen if I held it for a day?"

"Your arm could go numb. Have to go to hospital for sure!" said another student. All the students laughed.

"Very good. But during all this, did the weight of the glass change?" asked the teacher.

"No." the students said.

"Then what caused the arm ache and the muscle (肌肉) stress?"

The students fell silent for a moment.

"Put the glass down!" said one of the students.

"Exactly!" said the teacher. "The problems of life are something like this. Hold them for a few minutes in your head, and it seems OK. Think of them for a long time and they begin to make you ache. Hold them even longer and you will not be able to do anything. It's important to think of the  challenges(挑战)  in your life, but it' s even more important to put them down at the end of every day before you go to sleep. That way, you are not stressed. You wake up fresh and strong and can deal with any challenge that comes your way!"

Remember to put the glass down today.

Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your cell phone loses its signal, the television has no programs, and you can't get online with your computer.

What has happened? These are just the types of problems a solar storm (太阳风暴) might  cause. You may not think of storms as putting our society in danger.  But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares (太阳耀斑): large explosions near the sun that can give off lots of energy. The strong energy can stop the satellite systems (卫星系统) that operate our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine's Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

"Solar flare activity is going to be much worse than what we've seen in the past. We' re not talking about a few cities losing power. It could be half the country, maybe more," SolarStormWarning. com, a US website about space weather, warned.

Experts say that little can be done to predict (预测) such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

A. TVs cannot be turned on           B. mobile phones have no signals

C. people cannot get online              D. the satellite system will be stopped
