American is the country on the move. In unheard of numbers, people of all ages are exercising their way to better health. According to the latest figures, 59 percent of American adults exercise regularly—up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active. It’s hard not to get the message. The advantages of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the good points of doing regular physical exercises. Growing publicity(宣传) for races held in American cities helped develop a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally helpful and sometimes safer-forms of exercise.
As the popularity of exercise continues to increase, so does scientific evidence (根据) of its health benefit. The key to fitness is exercising the major muscle group strongly enough to almost double the heart rate and keep it doubles for 20 to 30 minutes at a time.

Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather．But water also can be dangerous for kids if you don't take great care．Nearly 1,000 kids die each year by drowning．
Here are some tips to keep your kids safe in the water:
At the Lake or Pond
○Don't let little kids swim alone without adult supervision— lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore．
○Ponds and lakes may hide jagged（锯齿状的）rocks, broken glass, or rubbish．
○Make sure kids wear foot protection; even in the water, they should wear socks or water shoes．
○Watch out for weeds and grass in the water that could trap a leg or arm．
○Most boating accidents, particularly among teenagers, are related to alcohol（饮酒）．Be sure teens know about the dangers of alcohol, on and off the water．
At the Beach
○Teach kids to always swim when and where a lifeguard is on duty．Unlike the calm waters of a swimming pool, the beach has special dangers like currents and tides（暗流）．Check with the lifeguard when you arrive to find out about the water conditions．
○Tell kids never to stand with their back to the water because a sudden wave can easily knock a child over．
○Teach kids that if they're caught in a dangerous wave, they should swim parallel（顺行地）to the shore or should tread （踩）water and call for a lifeguard's help．
Whether at the lake or at the beach, teach your child to get out of the water during bad weather, especially lightning．Which is the right behavior when swimming at the beach?
| A．Go off the water without a lifeguard on duty |
| B．Go on swimming in a heavy rain |
| C．Go off the water before checking the water conditions |
| D．Call for help if caught in a dangerous wave |
A child should_________ at a lake．

In which column（栏目）of a magazine can you find this passage?
| A．Education | B．Science | C．Entertainment | D．Sports |
If you are a human, you can’t help but experience the time when everything seems to be going wrong and you feel as if your life is completely out of control．It is during the low time that words of encouragement from family, friends, coworkers or even strangers can boost your spirits．It is also during the low time that destructive words can be devastating（毁灭性的）and make you sink deeper and deeper into depression．
For example, consider this story about a group of frogs who were traveling through the woods when two of them fell into a deep pit（深坑）．All of the other frogs gathered around the pit．When they saw how deep the pit was, they told the two unfortunate frogs they would never get out．
The two frogs ignored the comments and tried to jump out of the pit．The other frogs kept telling them to stop．Finally, one of the two frogs took notice of what the other frogs were saying and simply gave up．He died．The other frog continued to jump as hard as he could．Once again the crowd of frogs shouted at him to stop the pain．The more they shouted, the harder he jumped and finally he made it．
When he got out, the other frogs asked him why he continued to jump when they were all shouting at him to tell him to give up．The frog explained to them that he was a little bit deaf．He thought they were encouraging him the whole time．
Every time you have a chance to say either something positive or negative to another human being, do choose the chance to say something positive! Don’t let those opportunities get away from you．Your words have a large amount of power．Use them wisely．You really never know just how much they can mean to someone else．Why did the frog that succeeded in jumping to safety neglect（忽视）the other frogs’ comments?
| A．Because he would like to jump out of the pit． |
| B．Because he could hardly hear what the other frogs said． |
| C．Because he didn’t want to give up his hope． |
| D．Because he had a positive attitude toward life． |
What can we infer from the first paragraph?
| A．There is no way to go when we go wrong． |
| B．Life depends on encouragement． |
| C．Destructive words will lead to death． |
| D．Words are playing an important role around us． |
The writer mainly wants to tell us ________ in the last paragraph．

| B．positive words |
| C．negative words |
| D．the opportunities to say something |

Grandpa’s hobby was making birdhouses. He always said, “A man has to keep busy to stay out of trouble.” Leigh wasn’t sure how much trouble Grandpa could get into anyway, since he was such a nice man, but Leigh tried to listen to his advice. Besides, she liked to help on his birdhouses.
Grandpa’s shop was full of well-oiled and carefully-kept tools. Whenever he used something, he put it back in exactly the right place. He had rules about how he treated his tools, because he hated buying something new if the old one still worked. He also made sure to clean up each time he worked on something.
It wasn’t too fun cleaning up, but it was nice to watch him cut boards to exact lengths. It was nice to see the drill put in holes for screws(螺丝) to go in cleanly. It was like being a doctor, but with wood. The best part of building was seeing all the pieces come together in the final form.
The last steps always included lacquer or paint, to help protect Grandpa’s hard work from the weather. His birdhouses lasted for years. If he didn’t coat them properly, the sun and rain would turn the wood gray and weak in a short period of time. No, he always made sure to do things right. Even if he put rocks or other cute decorations on them, it was done right and made to last.
Grandpa was a hard worker, but he was also smart and generous. He let Leigh keep the birdhouses sometimes, but only if he got to help hang it up or set the post for it. It had to be done just right, after all.
The birdhouses were a great way to learn about woodworking, hard work, taking care of what you have, and about birds. The best thing about building birdhouses was that Leigh spent some time with Grandpa.What’s the best title for the text?
| A．Long-lasting Birdhouses |
| B．Birdhouses Making |
| C．Birdhouses, Home for Birds |
| D．Grandpa’s Birdhouses |
What did Leigh value most?
| A．Listening to Grandpa’s advice. |
| B．Helping Grandpa on his birdhouses. |
| C．Spending some time with Grandpa. |
| D．Learning about woodworking and birds. |
We can learn from the text that Grandpa ________.
| A．was a very good carpenter |
| B．lived a very hard life |
| C．didn’t care about cleaning up |
| D．kept thousands of birds |
Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.
People have been influenced to become technology addicted. One survey reported that “addicted” was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure of social media than they did for sleep, cigarettes and alcohol.
The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information , to keep pace with their peers or to appear modern.
I see people trapped in a pathological(病态的) relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude（奴役）. I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money.
What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that “too much of a good thing is wonderful.” But it’s time to discover that it does not work for technology.
Richard Fernandez, an executive coach at Google acknowledged that “we can be swept away by our technologies.” To break the grand digital connection people must consider how life long ago could be fantastic without today’s overused technology.The underlined word “allure” in Paragraph 2 probably means________.
| A．advantage | B．attraction |
| C．adaption | D．attempt |
From the passage, technology companies aim to_______.
| A．attract people to buy their products |
| B．provide the latest information |
| C．improve people’s quality of life |
| D．deal with cultural diseases |
It can be inferred from this passage that people ________.
| A．consider too much technology wonderful |
| B．have realized the harm of high-tech devices |
| C．can regain freedom without high-tech devices |
| D．may enjoy life better without overused technology |
What’s the author’s attitude towards the overusing of high-tech devices?
| A．Neutral. | B．Doubt. |
| C．Disapproving. | D．Sympathetic. |
