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.
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
4.This passage is mainly about .
A．music that teenagers like B．hearing problems caused by the loud world
C．ways that teenagers enjoy music D．dangerous modern lifestyles of teenagers.
There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books.
It would seem that there are three kinds of travel books. The first are those that give a personal, subjective(主观的) account of travels which the author has actually made himself. if they are informative and have a good index(索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective(客观的) description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called “a guide” to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way.
Whatever kind of travel book you choose you must make sure that it does not describe everything as “wonderful”, “excellent” or “magical”. You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.
This passage is about _______.
A. how to travel B. how to buy travel books
C. how to read a travel book D. travel books
The following travel books may be of use when you plan your travels except _______.
A. the book written by some people who have had the same travel experience themselves
B. the book which tells you what is worth doing and seeing based on the facts
C. the book in which a lot of big adjectives are used to draw your attention
D. the book which offers you a lot of useful information like a tour guide
The date of the publication must be noticed because _______.
A. the world is changing and so are the places you are going to visit
B. the price of the book is always changing
C. the author of the book may be different
D. the contents of the book are always the same
Preface
Science is a dominant(占优势的) theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.
This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive（普遍的；深入的）in our culture.
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not a unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.
We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.
According to the passage, ‘scientific subculture’ means
A cultural groups that are formed by scientists. B people whose knowledge of science is very limited.
C the scientific community. D people who make good contribution to science.

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another device out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.
“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time ，and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.
While it，s probable that Apple is definitely in a testing stage for its next smartphone , consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.
“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.
When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored devices when it revamped(更新，翻新）its iPod line last fall, so it’s not too much of a stretch to believe it would want the new twist with its smartphone, as well”.
“I wouldn’t be surprised if the new iPhone becomes available in some new colors，’’ he said. “That could be done pretty cheaply ，and it would give Apple a new marketing angle.”

A.tries to pleases its investors

A.the stage of its being tested
