Each new school year brings fresh reminders of what educators call the summer learning gap.Some call it the summer learning setback.Simply speaking,it means the longer kids are out of 'school,the more they forget.The only thing they might gain is weight. Most American schools follow a traditional nine-month calendar with winter and spring breaks and about ten weeks of summer vacation.Some schools follow a year-round calendar.They hold classes for about eight weeks at a time,with a few weeks off in between.The National Association for Year-Round Education says there were fewer than 3,000 such schools at last count.They were spread among forty-six of the fifty states. But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school.Lead researcher Paul von Hippel said,"Year-round schools don't really solve the problem of the summer learning setback.They simply spread it out across the year. Across the country,research shows that students from poor families fall farther behind over the summer than other students.Experts say this can be prevented.They note that many schools and local governments offer programs that can help. But calling them "summer school" could be a problem.The director of the summer learning center at Johns Hopkins,Ron Fairchild,said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term "summer school".In American culture,the idea of summer vacation is connected to beliefs about freedom and the joys of childhood.The parents welcomed other terms like "summer camp," "extra time" and "hands-on learning." Why did almost all parents dislike the term "summer school"? A) They cherish the children's rights of freedom very much. B) They are worried about the quality of the "summer school". C) They want their children to be forced to make up the gap. D) They can't afford to the further study during the vacation.

Film cameras and digital cameras work in a similar way. Film cameras After all, a film camera is basically a light - proof box. It has a lens system to focus light onto the film at the back of the camera. Let's suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let's say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed image on the film. When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog! Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them. Digital cameras In digital cameras, the light falls not on film but onto a sensor called a CCD (Charge Coupled Device). This digitally converts light and color into a digital information or pixels . The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is. In the "Film cameras" part, you fail to take the picture of the dog because _ . A) light goes into the camera lens and hits the shutter B) you haven't aimed the camera at the dog C) the image of the dog is not created D) the sensor fails to convert light and color into a digital information

Ques: An estimated eight million people in Britain enjoy walking in the Peak District every year. But what many who enjoy outdoor hobbies don't know is that their "right to walk" was won by men who sacrificed their own freedom to gain access to the countryside for all. In 1932 wealthy landowners had private use of large areas of uplands for hunting. Walkers were kept out by guards, until a group of 400 people from Manchester and Yorkshire, led by Benny Rothman, engaged on a mass trespass . The campaigner was put into prison with four other men. The event is supported by many with starting a movement that paved the way for the establishment of national parks. Mr Rothman died in 2002 but he is now being honoured for his contribution with the revealing of a blue plaque on his former home in Crofton Avenue, Timperley, Greater Manchester. Retired professor, Harry, who followed in his father's footsteps by specialising in environmental issues, says: "He was a very optimistic man and he made the best of it when he went to prison. It did''t put him off campaigning, he went on campaigning on environmental issues most of his life." Mr Rothman did live to see the Countryside Rights of Way Act passed by Parliament in 2000, ensuring the freedom of the countryside for future generations. Roly Smith, a friend of Mr Rothman and an author of walking guidebooks, said: "It is because of them that we have got what we have today." Councillor Jonathan Coupe, of Trafford Council, said: "The honour of having a blue plaque attributed to you means you have really made an impression on society." "Mr Rothman contributed to the changing of history and it is because of him that we are able to enjoy the local countryside as often and freely as we can today." What do we know about people in Britain according to Para. 1? A) They value freedom. B) They have wide interests. C) They are fond of hiking. D) They tend to live in the countryside.

Ques:In some parts of the United States, farming is easy. But farming has always been difficult in the northeastern corner of the country, which is called New England. New England has many trees and thin, rocky soil. Anyone who has wanted to start a new farm there has had to work very hard. The first job has been cutting down trees. The next job has been digging the stumps of the trees out of the soil. Then the farmer has had the difficult job of removing stones from his land. This work of removing stones never really ends, because every winter more stones appear. They come up through the thin soil from the rocks below. Farmers have to keep removing stones from the fields. Even today, farms which have been worked on for 200 years keep producing more stones. That is why stone walls are used instead of fences around New England fields. The stone walls are not high; a man can easily climb over them. But they keep the farmer's cows from joining his neighbor's cows. According to this selection farming is difficult in New England because _ . A) the winter is very long there B) the farms are very old C) the soil is rocky and thin D) the summer is too hot
