While serious training is important for all dogs, playtime is just as important. 1. Use these games to help teach your dog how to play.

1. Hide and Seek

Hide and seek isn’t just for kids. Dogs can really enjoy this game. Pick up one of your dog’s favorite toys or treats. Tell your dog to stay. 2. When you are ready, call your dog to come to you. If possible, squeak (使吱吱叫) the toy or shake the treats. Reward your dog with praise and the toy or treat when she finds you.

2. Fetch

Many dogs have a natural ability to fetch. Other dogs can be taught how. 3. Play indoors with a soft toy or outdoors in a fenced-in area with a ball or disc. For dogs that really love to run, try this game of fetch!

3. Find the Treat

Dogs have superior senses of smell, and most love to use their noses to find food. Let your dog use her brain and her nose to find hidden goodies. First, have your dog stay out of sight. Then, hide her favorite treats in various places around the room. 4. If help is needed, you can lead her around or point to areas for her to explore.

Whatever the game, safety comes first! Remember to watch your dog for signs of exhaustion or overheating when you are playing. Stop if your dog seems tired or shows signs of anxiety. 5. When other dogs or people are around, it may create a dangerous distraction.

A. Then, go to find a good hiding place.

B. Try different games to see which your dog responds to best.

C. A good game of fetch can be played almost anywhere.

D. You can include games in training as well.

E. Also be aware of your surroundings when playing with your dog.

F. Encourage your dog to play with other dogs.

G. Bring your dog back in and tell her to “go find!”

"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you.?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said. Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. "Waves are one of nature's ways of picking up energy and then sending it off on a journey." When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.

"The resource is huge," said Janet Swain of the World Watch Institute. "We will never run out of wave power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface---that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.

Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic. Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

1.The underlined phrase "picking up" is closest in meaning to ______.

A. starting again B. speeding up

C. improving D. gathering

2.We can make better use of wave energy if we ______.

A. shorten its journey to thousands of homes

B. build more small power stations on the oceans

C. reduce the cost of turning it into electric power

D. quicken the steps of producing electricity

3.It can be inferred that some day we might not worry about ______.

A. our power supply B. our boat traffic

C. air pollution D. our supply of sea fish

Boys’schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.

Far from the traditional image of a culture of aggressive masculinity(男子气概),the absence of girls gives boys the chance to develop without pressure to be consistent to a stereotype(传统观念),a US study says.

Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their abilities to express their emotions,rather than feeling they had to obey the “boy code” of hiding their emotions to be a “real man”.

The findings of the study are against the received wisdom that boys do better when taught alongside girls.

Tony Little,headmaster of Eton,warned that boys were being ignored by the British education system because it had become too focused on girls.He criticized teachers for failing to recognize that boys are actually more emotional than girls.

The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.

But in single-sex schools teachers can adjust lessons to boys’ learning style,letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study’s author, Abigail James of the University of Virginia.

Teachers could encourage boys to enjoy reading and writing with “boy-focused” approaches such as themes and characters that appeal to them.Because boys generally have sharper vision,learn best through touch, and are physically more active, they need to be given “hands-on” lessons where they are allowed to walk around.” Boys in mixed schools view classical music as feminine(女性的)and prefer the modern type in which violence and sexism are major themes.” James wrote.

Single-sex education also made it less likely that boys would feel they had to give in to a stereotype that men should be “masterful and in charge” in relationships.“In mixed schools boys feel pressed to act like men before they understand themselves well enough to know what that means.” the study reported.

1.The author believes that a single-sex school would

A.force boys to hide their emotions to be “real men”

B.help to form masculine aggressiveness in boys

C.encourage boys to express their emotions more freely

D.naturally place emphasis on the traditional image of a man to boys

2.It is commonly believed that in a mixed school boys

A.perform relatively better

B.grow up more healthily

C.behave more responsibly

D.receive a better education

3.What does Tony Little say about the British education system?

A.It fails more boys than girls academically.

B.It focuses more on mixed school education.

C.It fails to give boys the attention they need.

D.It places more pressure on boys than on girls.

4.According to Abigail James,one of the advantages of single-sex schools is

A. teaching can be designed to promote boys’ team spirit

B.boys can focus on their lessons without being absent-minded

C.boys can choose to learn whatever they are interested in

D. teaching can be adapted to suit the characteristics of boys

Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear different home schooling teachers discuss history, I get the idea that there may be different reasons for teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons for studying history.

The major reason I see for studying history is that we can learn from the past. I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures. However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in teaching history, to my children I can do a small part in changing this.

The second major reason for studying history is that it is hard to understand the current political climate in the absence of an understanding of its historical context. We can not even understand why we are and where we are without history, much less (更不必说) try to figure out where we are going or how we should get where we want to be.

I teach my children history, for one more reason. I purchased a set of historical audio (录音机) tapes for our children. My seven-year-old son listened to them over and over. It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr. if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for.

1. In Paragraph 3, the author shows that history is useful because _______________.

A. it makes the current political situation go smoothly

B. it helps us realize the importance of historical events

C. it helps us understand why things are the way they are

D. it helps people accept the present situation where they live

2.Some historical figures(人物) are mentioned in the last paragraph to show ______________.

A. people can be inspired to do good, while also learning to fight against evil

B. people may also learn from bad historical figures

C. more celebrations should be held to honor their achievements

D. today’s people can also achieve what they achieved

3. What would be talked about in the following paragraph?

A. How to teach history effectively.

B. Some negative reasons for studying history.

C. How to get more people to study history.

D. Some bad historical figures.

4. The main purpose of this passage is to ____________.

A. inspire the parents to teach their children history

B. show the importance of history in politics

C. explain the reasons why children study history

D. introduce the writer' s own way of teaching history
