Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight. A recent research has found a new recipe for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk ‘Dog’, and dogs can learn how to talk ‘Cat’.

What’s interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other’s body signals, suggesting that the two may have more in common than was previously suspected. Once familiar with each other’s presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The significance of this research on cats and dogs may go beyond pets ─ to people who don’t get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests．That was the finding of a study of teenage males in Norway．Now，other research shows that physical activity may help students do better in their classes .

The research comes as educators in some countries are reducing time for activities like physical education．They are using the time instead for academic subjects like maths and reading．The studies appeared between 2007 and 2013．They included more than 55，000 children，aged 6 to 18．

Amika Singh：“Based on the results of our study，we can conclude that being physically active is beneficial for academic performance. There are，first，Physiological explanations，like more blood flow, and so more oxygen to the brain．Being physically active means there are more hormones(荷尔蒙)produced like endorphins(内啡肽)．And endorphins make your stress level lower and? your mood improved, which means you also perform better.”

Also，students involved in organized sports learn rules and how to follow them．This could improve their classroom behavior and help them keep their mind on their work．

The study leaves some questions unanswered，however．Ms．Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement．This is because of differences among the studies .

Also．they were mostly observational studies．An observational study is where researchers do not do controlled comparisons．They only describe what they observe．So they might observe a link that students who are more active often have better grades．But that does not necessarily mean being active was the cause of those higher grades．

The researchers said they found only two high - quality studies．They called for more high-

quality studies to confirm their findings．They also pointed out that “outcomes for other parts of the world may be quite different. ”

Still，the general finding was that physically active kids are more likely to do better in school．Ms．Singh says schools should consider that finding before they cut physical education programs．Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine．

1.The passage mainly tells us that ＿＿＿＿

A．a research on physical education has been done by the researchers

B．there exists a possibility that physical activity leads to higher grades

C．the amount or kind of activity directly affects academic level

D．the research shows that the children aged 6 to 1 8 don't do sports

2.Which of the following is TRUE?

A．Being mentally active is good for academic subjects．

B．The more hormones you have，the more stressed you will get．

C．They have found many high-quality studies to prove the research．

D．The educators in the research think studies，not exercise，mean much to students．

3.The underlined sentence in Paragraph 7 probably means ＿＿＿＿.

A．good marks result from high-quality study

B．findings probably vary in different areas

C．physical activity will spread all over the world

D．academic performance depends on the surroundings

4.What's the purpose of writing the passage?

A．To call our attention to the sports at school．

B．To introduce all types of physical activities．

C．To represent the academic performance．

D．To improve students' health ．

【小题1】The underlined word swimmingly in Paragraph 1 is closest in meaning to ______.

Among the Boys is a unique after-school program for boys living in the Highland Park neighborhood of our city. The organizational task is to provide males living in low-income and public housing with opportunities to discover their ability to change challenges into possibilities. The program includes an academic part as well as specific plans for supporting the overall development of the participants. Among the Boys uses painting as an instrument for helping boys examine their world, discuss it, and develop positive ways of handling the challenges they face daily. Young men present personal challenges to the group, such as a recent fight or the long-term drug abuse they observe in their neighborhood. After guided discussion, the youth work as a team, determining how to best represent the issue at hand in a painting. The resulting paintings and explanations of these paintings provided by the young people suggest that something profound(深远的) occurs through this process. These young men are learning a healthy way to express and cope with the pain and suffering they feel. Art serves as a healing process and a structured method of teaching teamwork, nonviolent values, conflict handling and problem-solving skills.

Activities in Among the Boys are in agreement with the best practices in the prevention of high-risk behavior. First, community-based youth development programs are considered important parts of a comprehensive prevention method, particularly in high-risk neighborhoods. Second, compensatory(补偿) education that targets at risk youth for academic failure is also considered an effective prevention method. Third, interventions(介入) aimed at improving youth’s moral reasoning, social problem-solving, and thinking skills are reported to be effective methods for reducing violence in high-risk populations, especially when carried out with elementary school-aged boys. Finally, Among the Boys has an adapted tutoring part, considered an effective prevention tool. Tutoring is typically a one-to-one match between a tutor and a youth, but Among the Boys employs what is referred to as “group tutoring.” Among the Boys makes up for its high student-tutor ratio(比例) with quality and quantity of time, as the program meets after school, on Saturdays, and all day during the summer, and is staffed primarily by males, an unusual quality among educational programs.

Among the Boys is rare and successful form of grassroots program, and represents the dream of a successful male who grew up in the Highland Park neighborhood and has returned to make a valuable contribution to his community.
