Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older, we are unable to hear some sounds with high frequencies(频率). As a result, a child or teenager can hear the mosquitotone ringtone, but it’s inaudible to someone 20 or older.
But sometimes, people over 20 can hear the ringtone. One British student’s phone uses mosquitotone. In class, the student’s phone rang. The 32-year-old teacher looked at the student and became unhappy. “I heard that. You know the rule: no mobile phone in class.”
Not all the students are interested in mosquitotone. Jerry Jones, a high school student of 17, says, “Using mosquitotone too often is bad of our hearing. I may use it for pleasure, but not in class. It’s unfair to the teachers!”
What do parents think of mosquitotone? “I think it is perfect for places like movies theaters.” says Connie Neeson, 44. “Think about it. You’re watching a film and someone’s mobile phone rings. Mosquitotone is good because many people don’t hear it. However, it also has a bad influence on their study if students use it in class.”
48. Mosquitotone works because _________.
A. it is very loud B. it has no sound

49. The underlined part “it’s inaudible to” means “______”.

【2011浙江台州】（选择型）D
Think back to a time in your life when you tried something new.
When I was a teenager I volunteered to pass out water at a local race. I was so excited to see all the different runners who passed by and quickly took a cup of water. Some ran past, some walked past and a few wheeled past.
I saw so many types of people doing it. I thought maybe I could do it too! The next year I decided to run for the race, but I had little running practice. I just wanted to finish.
On the day of the race, it was terribly hot. After running for about 5 miles. I was thinking, “I must be crazy. Why did I do this? What was I thinking?” And at one moment, I said to myself, “I am never doing this again!”
That first 10 km race was quite an experience. I jogged(慢跑),I walked, I jogged and walked. At times, I didn’t know if I could finish.
Near the end, a 70-year-old man ran past me, very fast, and I felt a little embarrassed（尴尬的）that I was more than 50 years younger than he and I couldn’t even keep up with him. But then I realized something. He was running his race and I was running mine. How often in life do we compare（比较）ourselves to others when we really shouldn’t? I decided that I would not give up on running races, and that one day I would be one of those 70-year-old men who were still running.
As I crossed the finishing line, I was proud of myself. I didn’t regret（后悔）having such an experience.
