Should children have less time off school during the summer？Ruby Mullin， nineThis idea is mean； theres no other word for it. Children need to calm down and have a good holiday at the end of a busy school year. The long holidays give you time to do things you wouldnt otherwise get to do， like in my family we go to Ireland and see relatives and friends there. And it might seem long to some people， but time flies when youre having fun.Anthony Seldon， head teacher of Wellington College in BerkshireIf it hadnt been for the long summer holiday， I wouldnt have come into teaching. Its important for teachers to do other things as well as teaching， whether its painting， hiking or， as in my case， writing booksit adds such a lot to what teachers have to give. And as for all these worries about pupils forgetting all theyve learned， children have up to nine weeks in the summer， and their exam results dont suffer. We all know that some of the most valuable learning experiences take place away from the classroom.Nachelle Crowther， mother of threeA shorter summer holiday would be much better. The six-week break seems designed for another age， when mothers didnt work and your mum lived round the corner to give you a hand. If I was able to take a six-week holiday， great， Id love itbut in the real world that isnt possible. Instead， I end up spending a fortunearound 600on childcare for each week when Im working.Sarah Radford， a primary school teacher at Botley school， OxfordIve taught for more than 20 years， and summer is the only holiday when teachers can properly switch off from the intense work of planning and assessing(评估).If it was shortened， the result would be an increase in teachers stress levels and a harmful effect on our ability to teach. Children need that time for unstructured play， and to have time not being assessed， simply being themselves. And then school lessons in autumn will help their learning when theyre back in the classroom.1. The author wrote the passage to_. A. ask for advice about the summer break B. tell that the school holidays have to change C. advise children to have less time off school D. show different attitudes to a shorter summer break2. What can we learn about Anthony Seldon from the passage？ A. He used to go to Ireland during the holiday with his family. B. He began to work as a teacher because of the long summer holiday. C. He still had good exam results after nine weeks rest in the summer. D. Most of his learning experiences came from lessons in school.3. According to Sarah Radford， shorter summer breaks would _. A. do harm to childrens learning B. assess children properly C. improve teachers life D. make parents more stressful4. Taken from the website， the passage can be found in the column about _. A. societyB. education C. familyD. lifestyleBKids can be taught valuable lessons on nature from the time they are old enough to observe their surroundings. With the help of a parent， grandparent or caregiver， a small child can learn to explore parks， wooded areas and gardens. Parents and caregivers should take every available opportunity to introduce them to plant life， beneficial insects， wildlife and more. These types of lessons are important.One of the best ways to explore nature with a small child is on their level. Look for wildflowers， and point out their beautiful colors and patterns. Even a very small child can learn to recognize wildflowers. However， it is important to teach a small child the importance of leaving nature untouched for others to enjoy. Leaving wildflowers alone will allow them to spread and continue their life cycle. They look beautiful in a vase， but they are even more lovely in their natural habitat(生长地).The world in between blades of grass and under the leaves of flowers is seldom seen by human beings. When looking for ways to explore nature with a small child， take the time to get down on the ground and look for insects including ants， fireflies， ladybugs， earthworms and caterpillars(毛毛虫).A child should be taught that living beings are not toys. They have feelings and needs. A small child should be taught that life is valuable to every living creature. Kids that are taught to respect nature will grow to be more caring adults.Plant life is also an important part of our environment， and it is fun to explore with a child of any age. Plant some vegetables or flower seeds when seeking additional ways to explore nature with a small child. If space is lacking， start a small container garden. Fill a pot with rich organic soil(有机质土壤)，and have the child help plant the seeds and care for the seeds as they grow. Not only is it fun and educational， but it is also a good experience that can have a positive effect on a small child.5. When should a kid take valuable lessons on nature？ A. The younger the better. B. When he is old enough to go to school. C. When he is old enough to walk. D. When he can see and notice.6. What is important while the kids are watching wildflowers？ A. Teaching them how the wildflowers grow. B. Telling them to protect nature and appreciate its beauty. C. Telling them the patterns and colors of the wildflowers. D. Teaching them how to recognize the wildflowers.7. People should introduce kids to plant life and insects in order to make them _. A. respect nature and grow into more caring persons B. get to know the importance of exploring nature C. gain more knowledge and love science D. use various methods to observe the world8. In Paragraph 3 the author tells us to _. A. encourage a child to play with insects B. protect whatever insects we discover C. show a child the world that he rarely sees D. let a kid know insects are all good for usCVolunteers4india or V4I is a brand owned by INRI Charitable Trust， a non-profit and non-governmental organization(NGO).The founder of V4I has worked for social causes for several years.
