Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms(症状), you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume(最大音量), and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance(修理)person under a jet airplane or using a jackhammer(手提钻)on a building site.
Similarly, iPod music can cause a short time or permanent(永久的)hearing damage. A loud iPod can cause a ruptured(破裂的)eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves(听觉神经)that connect to the brain. If this happens, hearing loss becomes permanent.
【小题1】Which of the following shows that you are suffering hearing loss?

A.You are interested to listen to others’ talking.
B.You have to read others’ expressions to understand them.
C.You can only understand others over the phone.
D.You always think you hear the ringing of the phone.
【小题2】 Which of the following is TRUE when you listen to music?
A.Listen at least an hour every time.
B.Turn up the volume to the highest level.
C.keep the sound lower than 60% of its highest volume.
D.Choose classical, rock or heavy metal music.
【小题3】What is the correct order of causing permanent hearing loss?
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.

【小题4】This passage is mainly about      .
A.music that teenagers likeB.hearing problems caused by the loud world
C.ways that teenagers enjoy music D.dangerous modern lifestyles of teenagers.

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.

“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not  to touch it.”

“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”

Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.

It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”

“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:

“ENTER NAMES

    VOYAGE 1

    VOYAGE 2

    Mark’s finger flew across the keyboard as he typed in both of their names.

    “INPUT ACCEPTED.

    START  TRANSPORT  PROGRAM.

    AUTO-RETRIEVE  INITIATED(自动回收程序已启动).

    The screen turn even brighter and a noise suddenly rose in volume.

    “I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒),until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed:

“TRANSPORT SUCCESSFUL.

    DESTINATION:  MARS.

RETRIEVE DATE:  2025

It’s parents’ worst nightmare. Their child doesn’t come home one evening and is missing for several days.

    When a 14-year-old boy from Atlanta, Georgia disappeared earlier this year, his mother turned to her Smartphone for clues using an app(应用程序) called Family Tracker that helped track his location.

    “You can see where your loved ones are without having to call or bother them. ”said Roberto Franceschetti of LogSat, the creators of the Family Tracker, which has more than 100,000 users and is available worldwide.

    Parents can track the location of their child on a map, send messages, and even sound an alarm on the phone in a long distance.

    “We have an option for the sender to make a very unpleasant, noisy sound. It’s a loud alarm and we repeat that sound every two minutes until the person picks it up, ”he said.

    Parents don’t need to own a Smartphone to track their children. The service is also accessible through the web, as long as the phone that is being tracked is running the app.

    Family Tracker has an additional service that keeps records of all data from the app for a two-week period, which the company calls GPS breadcrumbs.

    “With a subscription(预定), we keep all the locations where people have been on our servers. You can see where your kid has been for the past two weeks. You can find out where someone was at a certain time or when that person was at a specific place, ”Franceschetti explained.

    “When somebody gets abducted(劫持), usually whoever does this throws the phone away or takes the battery out. We were hoping that our app would at least provide information on where the person was abducted or where they had been in the past. ”

    But will these types of apps let out personal secrets?

    “The advantages are huge compared to the disadvantages. Let’s not forget that the person always has to give initial permission—no one can be tracked unless they allow someone to do it. ”said Franceschetti.

A. it can help parents know where their children are

B. all parents don’t need to own a Smartphone to track children

C. parents can use all the services of the app for free

D. it has little to do with letting out personal secrets

2.What can we infer from the passage?

B. The loss of children won’t be a nightmare for parents any more.

C. The app will repeat the loud alarm continuously whenever parents track children.

D. The app can keep records of information for more than half a month.

3.Which belong to the functions of the new app?

a. track location    b. detect criminals          c. send messages

d. protect privacy           e. send remote alarm      f. record information

A. a, b, c, e    B. a, c, e, f               C. a, c, d, e               D. a, d, e, f
