For a while, my neighborhood was taken ever by an army of joggers. They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great." Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army, I'm not alone in my opinion. First of all, jogging is very hard on the body. Your legs and feet need a real pounding running down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring _ out, as they did with me. Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts" Well, my thoughts began to bore me, and most of them were on how much my legs hurt. And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog? I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say... Why did the writer give up jogging two months later? A) He disliked doing exercise outside. B) He found it neither healthy nor interesting. C) He was afraid of having a heart attack. D) He was worried about being left alone.

There are an extremely large number of antsworldwide. Each individual ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective intelligence greater than you would expect from itsindividual parts. Ants can use pheromones for _ . A) escape B) communication C) warning enemies D) arranging labor

Katie always felt there had to be something more to life than just partying, buying clothes and driving a cool car. She finally discovered what she was missing out on when she traveled halfway around the world to help poor kids. When she was 14, she discovered a club at school called Operation Smile, an organization that supports free operation for facially deformed kids in developing countries. At that time, she joined Operation Smile just to satisfy her school's community service requirement. After working with Operation Smile for a while, she learned different countries have different deformities . The more she learned about what affects kids around the world, the more she wanted to go abroad with Operation Smile. At 15, she was chosen to go abroad. She was so happy - even though she didn't realize what she was getting herself into. Before her trip, she attended a weekend "mission training". That's when she was told she'd be going to the Philippines. Although she was excited, one night during training, she broke down in tears. She didn't know if she was prepared to see all these unfortunate kids. She was put to work three days after her arrival in the Philippines. Her first day was at the hospital, where she met those kids waiting for operation, and they were running around and happy, it seemed normal. Her job was to play with the kids before their operation to help them feel more at ease. She also went to nearby schools to hand out toothbrushes and teach students how to brush their teeth. When their operation was over, the kids were always overjoyed, but their parents were blown away. Sometimes they couldn't even recognize their kids because their appearances had improved so much. They'd cry and hug the doctors and nurses and give them presents--they were so grateful. Why did the author join the Operation Smile? A) To help poor kids in developing countries, B) To satisfy her own curiosity. C) To do what was required by the school. D) To operate on those unfortunate kids.
