题目：Today children find it difficult to concentrate or pay attention at school. What do you think are the causes? What are the solutions?

范文：Being able to concentrate and focus for sustained periods is a skill that children will need to develop in order to make the most of their education. While most children will naturally develop a greater attention span as they grow older and get used to the school environment and expectations, some continue to struggle to focus on a task or an activity.

ln this digital age of smart phones and socia1 media, there are plenty of distractions to tempt the wandering mind where study tasks are concerned. From surfing the webpage to instant messaging, constant distractions compete for children's attention. lt is not uncommon to witness a childlistening to his iPod while doing his homework. With so many potential interruptions, it can be difficult for children to stop and focus on the task at hand.

There are some practical and manageabletipsteachers and parents can use to helptheir children focus, complete their task both at school and home and ultimately succeed. lnitiallY, setting early expectations is an essential start, such as explaining to children their priorities at school and home and in the community The earlier teachers and parents set expectations and establish a routine for studying, the easier it will be to maintain. AdditionallY, managing and minimizing the number of distractions that can pull a child's focus away is another important step. Parents can help their children by insisting that certain responsibilities are met before privileges are granted. That is because young people sometimes have a tendency to prioritize short-term needs and wants overlonger- term goals.

To conclude, helping children develop self-dlscipline, effective focus strategies and concentration skills at an early age is a basis forlong-term success in high school, college and the professional working world. Therefore, teachers and parents should put more consideration into the issue.

1 There’s a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100，000 years - exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star’s core.

2 Robert Ehrlich of George Mason University in Fairfax， Virginia， modelled the effect of temperature fluctuations in the sun’s interior. According to the standard view， the temperature of the sun’s core is held constant by the opposing pressures of gravity and nuclear fusion. However， Ehrlich believed that slight variations should be possible.

3 He took as his starting point the work of Attila Grandpierre of the Konkoly Observatory of the Hungarian Academy of Sciences. In 2005， Grandpierre and a collaborator， Gábor ágoston， calculated that magnetic fields in the sun’s core could produce small instabilities in the solar plasma. These instabilities would induce localised oscillations in temperature.

4 Ehrlich’s model shows that whilst most of these oscillations cancel each other out， some reinforce one another and become long-lived temperature variations. The favoured frequencies allow the sun’s core temperature to oscillate around its average temperature of 13.6 million kelvin in cycles lasting either 100，000 or 41，000 years. Ehrlich says that random interactions within the sun’s magnetic field could flip the fluctuations from one cycle length to the other.

5 These two timescales are instantly recognisable to anyone familiar with Earth’s ice ages： for the past million years， ice ages have occurred roughly every 100，000 years. Before that， they occurred roughly every 41，000 years.

6 Most scientists believe that the ice ages are the result of subtle changes in Earth’s orbit， known as the Milankovitch cycles. One such cycle describes the way Earth’s orbit gradually changes shape from a circle to a slight ellipse and back again roughly every 100，000 years. The theory says this alters the amount of solar radiation that Earth receives， triggering the ice ages. However， a persistent problem with this theory has been its inability to explain why the ice ages changed frequency a million years ago.

7 "In Milankovitch， there is certainly no good idea why the frequency should change from one to another，" says Neil Edwards， a climatologist at the Open University in Milton Keynes， UK. Nor is the transition problem the only one the Milankovitch theory faces. Ehrlich and other critics claim that the temperature variations caused by Milankovitch cycles are simply not big enough to drive ice ages.
