Simply speaking, it means that the longer kids are
26、out of school, the more they forget. The only thing they might gain is weight.Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight wee
27、ks 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 genera
28、lly the same as in a traditional school. Lead researcher Paul von Hippel said, “Year-round schools dont 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
29、 summer vacation 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
30、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”, “enrichment”,
31、“extra time” and “hands-on learning”. 39. According to the first paragraph, the summer learning gap _.

35、 University biologists show that in the plant world, bigger isnt necessarily better. “Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” says Queens Biology professor Lonnie Aarssen. “But our research shows its virtually the other wa
36、y around.”Previous studies revealed that larger plant species monopolize(垄断) sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But new research has proven that this is not generally the case in natural vegetation.In the Queens project, PhD
37、student Laura Keating targeted the largest individuals or “host plants” of 16 woody plant species growing in the Okanagan Valley, British Columbia. The research team calculated the number and the variety of plants that neighbored each large host plant. They then randomly selected plots without host
38、plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist.Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space nich
39、es under their canopies where smaller species thrive. Smaller plants are much more effective than large trees at utilizing available resources. They also produce seeds at a much younger age and a higher rate than their bigger counterparts, and establish much more quicklythus competing with the seedl

To be a good competitor in the forest, you have to be a small plant.D. Queens Universitys students made
41、a new research. 44. The underlined word “this” in Para. 3 refers to the view that _. A. large and small plants can grow together in harmony B. larger plant species limit their smaller neighbors growthC. small plant species have their own advantagesD. large and small plant species can never coexist45
42、. What can we learn according to the text? A. Larger plant species limit the number of smaller ones around them.B. Smaller plants can limit the number of plant species around them. C. Smaller plants produce seeds at a higher rate than their bigger counterparts.D. Larger trees are more effective than
43、 small plants at using available resources.46. Which is the CORRECT order in the Queens project?a. Randomly selected plots without host plants and calculated the plant species.b.

46、 a back window and pulled Mallory Smith, 10, and her sister, Megan Smith, 9, from the wreckage.The girls mother, Beckie Smith, was not with them at the time of the wreck, as they were traveling with their babysitter, Lisa Bowbin.Beckie Smith still remembered the sickening feeling she had upon receiv
47、ing the call informing her of the wreck and the despair as she drove to the scene.Bozeman and Clemmons arrived shortly after Bonge and helped rescue the other victims and attempted to put out the fires.“I was nervous,” Bozeman said, “I dont feel like Im a hero. I was just doing what anyone should do
48、 in that situation. I hope someone would do the same for me.”Everyone at the accident made it out alive, with the victims suffering from non-lifethreatening injuries.

Their achievements are reflected in the nations best universities, where mathematics, science and engineering de
55、partments have taken on a decidedly Asian character.

Many researchers also believe there is something in Asian culture that results in success, such as ideals that stress family values and emphasize education.Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image.
