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 , 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 , 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 person under a jet airplane or using a jackhammer（手提鉆）on a building site.

Similarly, iPod music can cause a short time or permanent 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（聽(tīng)覺(jué)神經(jīng)）that connect to the brain. If this happens, hearing loss becomes permanent.

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.

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.

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.

A. d-a-c-b-e B. e-c-a-b-d

C. b-c-a-d-e D. d-e-a-c-b

Think for a moment about the teachers you’ve had at junior or senior high school. Which one did you like best? And why? Were the teachers you liked best also the ones who were the best teachers, in your opinion? 1.And then begin to read further.

Some very common answers to this question are that teachers need to love their students, that they need to have expert knowledge of their subjects and that they should devote themselves completely to their work. All of these ideas are, of course, true to a certain extent.2.

It’s impossible for anyone to love everyone he knows, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they’re interested in them as people. 3. A deep knowledge of the subject is especially important.4. That’s to say, a teacher needs to be trained in the skills of teaching. These skills include how to control a class. Finally, teachers have to devote a lot of time and energy to their work, of course. However, because they’re also models that their students must follow, it’s important that they should be well-balanced people with interests outside their school work—families, friends, hobbies, etc. 5.

A.They’re perhaps a little too simple.

B.Students ask too much from teachers.

C.Well- qualified teachers should be educated and capable.

D.Consider for a minute the qualities that make a teacher outstanding.

E.A teacher who only lives for work is likely to become narrow-minded.

F.Equally important is the ability to pass that knowledge on to the students effectively.

G.They also pay attention to the development of both their brains and their characters.

Noticing the signals that people send out with their body language is a very useful social skill.1.Fortunately, with a little extra effort, you can learn to read body language, and with enough practice it'll become second nature.

2.The closer they are, the warmer they are thinking of you. The farther away that someone is, the less they actually care about the situation or person. If you move slightly closer to them, do they move slightly further away? That means they don't want your communication to be any more personal than it already is.3.And if they respond by getting even closer to you, they probably really like you or are very comfortable around/by you.

It is worth noting that personal space is culturally different; keep in mind that what is considered close in one country is far away in another.

Check their arms.4.Though some people just cross their arms as a habit, it may indicate that the person is slightly reserved, nervous or embarrassed about their appearance and trying to cover it, or just trying to hide something on their shirt. If their arms are crossed while their feet are wider apart, this is a position of toughness or authority. If someone rests their arms behind their neck or head, they are open to what is being discussed or just easy-going in general. If their hands are on their hips(雙手叉腰), they might be waiting, impatient or just tired.5.

A. If they don't move further away, then they are willing to listen and accept.

B. How to read body language needs to be learned.

C. Some of us can read it naturally and some of us can’t at all.

D. If their hands are closed, they may be angry, or nervous.

E. People with crossed arms are closing themselves to social influence.

F. Pay attention to how close someone is to you.

G. Some people tend not to move further away.

The House at Pooh Corner

by A. A. Milne

I bought a box set of four Winnie the Pooh books while on holiday when I was eight years old. I adored Pooh, Piglet, Tigger and Eeyore. They became very real to me and I credit them with starting a lifelong love of reading.

I still have the box set, and loved reading the stories to my children when they were small. Part of me secretly believes A. A. Milne’s wonderful characters are all alive and well and still having their adventures in the Hundred Acre Wood.

—Roberta Smith

Jane Eyre and Wuthering Heights

by Charlotte and Emily Bront?

I can never separate Charlotte Bront?’s Jane Eyre and Emily Bront?’s Wuthering Heights when I think about books that have stayed with me. Both had a deep impact on me when I read them as a teenager.

They were the first classic books I read purely for pleasure, rather than because I had to for school.

I grew up in Yorkshire, not far from where the Bront?s lived, so part of me really understood that depressing landscape. That close geographical connection led to a lifelong interest in the authors as much as in the books themselves.

I wrote a high-school essay on the contrasts and similarities between Charlotte and Emily and their heroines. I’d be fascinated to read that essay now to see what conclusions I reached as a 17-year-old.

— Jane Lee

1.What can we infer about the Winnie the Pooh books?

A. They are very realistic.

B. They describe holiday stories.

C. They are intended for children.

D. They encourage people to have adventures.

2.What is one reason the writer likes Jane Eyre and Wuthering Heights?

A. They were easy-to-find classic novels.

B. The stories helped the writer with her essay writing.

C. They were recommended by the teachers in her school.

D. The stories are set in an area that the writer knows well.

3.What’s the purpose of the text?

A. To introduce the books’ authors.

B. To promote some classical literature.

C. To comment on the books’ main characters.

D. To explain the effect of these books on the readers.
