Of all the websites，one that has attracted attention recently is myspace.com．Most of this attention has come from the media and tells every reason why the website should be shut down．The threat of internet predators（窃掠者）is indeed a tough reality，but shutting down the site is not the answer．If myspace.com were shut down，another site would quickly take its place．Therefore，the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them.

The key to staying safe on the Internet is to make sure that your profile（个人资料）is secure．The simplest way is to change the privacy setting on your profile to “private”, which protects your information so that only the people on your friend list can view it．Although this is effective，it is not perfect．Predators can find ways to view your profile if they really want to，whether through hacking in or figuring out their way onto your friend list．Thus，you should never post too much personal information．Some people actually post their home and school addresses，date of birth，and other personal information, often letting predators know exactly where they will be and when．The most information that is safe is your first name and province．Anything more is basically inviting a predator into your life.

Another big issue is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission．

Most importantly, never，under any circumstances，agree to a real-life meeting with anyone you meet online．No matter how well you think you know this person, there are no guarantees that they have told the truth．But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are．Hopefully，the next time you edit your profile，you’ll be more informed about the dangers of internet predators and take the steps to defend yourself.

A mum saved her daughter’s life with her newly learned first aid skills. Sonya Hall, 33, of Denny Avenue, Lancaster, had only just attended one first aid class the day before when she found herself needing to use the skills on her three year old daughter Tilly.
Sonya, who also has son Emmen, six, attended the first aid course at Lune Park Children’s Centre in Lancaster. Then she was faced with every parent’s worst nightmare when Tilly went blue in the face and stopped breathing. But thanks to her newly acquired skills, Sonya saved Tilly’s life.
Sonya said: “Tilly was playing with her brother and they were fighting over a toy. Emmen won the fight. Tilly fell backwards and her head was hit. She was face down and shaking and at first I thought she was upset. But then I saw she was blue in the face and had stopped breathing. I reacted without thinking and immediately started using the first aid skills I had learned the day before which were so fresh in my mind. I began doing mouth-to-mouth and chest compressions (胸外按压). It probably took about a minute before Tilly started breathing again, but to me it felt like a lifetime.”
After getting Tilly breathing again, Sonya called an ambulance and the doctors came. Since then, Tilly has been diagnosed (诊断) with Reflex Anoxic Seizure (反射缺氧发作). Sonya said: “The seizure can happen when there’s any unexpected pain, fear or fright. It is just so lucky that the day before it happened, I had been practising first aid.”
The Empowering Parents First Aid course is run by Lancashire Adult Learning. Sonya said: “I am just so glad I did the course and learnt the first aid skills. I always feared I would not know what to do in a crisis situation, but luckily I had the knowledge and skills to deal with it.”

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

When the star begins to die ______.

For many parents , raising a teenager is like fighting a long war ,but years go by without any clear winner . Like a border conflict between neighboring countries ,the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace ,but neither feels it has any power to stop the conflict . In part ,this is because neither is willing to admit .any responsibility for starting it . From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course .the  teens see it in exactly the same way , except oppositely . Both feel trapped

In this article. I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over         unimportant things . Examples include the color of the teen’s hair, the cleanliness of the bedroom ,the preferred style of clothing , the child’s failure to eat a good breakfast before school ,or his tendency to sleep until noon on the weekends .Second ,blaming , the goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong . Third , needing to be right ,It doesn’t matter what the topic is –politics. The taws of physics ,or the proper way to break an egg –the point of these arguments is to prove that you are right and the other person is wrong .for both wish to be considered an authority --- someone who actually knows something --- and  therefore to command respect. Unfortunately , as long as long as parents and teens continue to assume that they know more than the other ,they’ll continue to fight these battles forever and never make any real progress

A woman renewing her driver’s license at the County Clerk’s office was asked to state her occupation．She hesitated, uncertain how to classify herself．

“What I mean is,” explained the recorder, “do you have a job, or are you just a …”

“Of course I have a job,” said Emily．“I’m a mother.”

“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.

       One day I found myself in the same situation．The clerk was obviously a career woman, confident and possessed of a high sounding title．“What is your occupation?” she asked．

       The words simply popped out．“I’m a Research Associate in the field of Child Development and Human Relations.”

       The clerk paused, ballpoint pen frozen in midair.

       I repeated the title slowly, and then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.

       “Might I ask,” said the clerk with new interest, “Just what you do in this field?”

       Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t）, in the lab and in the field (normally I would have said indoors and out)．Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it)．But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”

       There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out．

       As I drove into our driveway, buoyed up (依托) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.

       Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern．

       I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”

       Motherhood…What a glorious career! Especially when there’s a title on the door.

       A．The woman felt ashamed to admit what her job was.

       B．The recorder was impatient and rude.

       C．The author was upset about the situation that mothers faced.

       D．Motherhood was not recognized and respected as a job by society.

How did the female clerk feel at first when the author told her occupation?

How did the author feel when describing her job to the clerk?

     A．calm     B．panic-stricken      C．confident      D．cool

Why did the woman clerk show more respect for the author?

       A．Because the author cared little about rewards.

       B．Because she admired the author’s research work in the lab.

       C．Because she thought the author did admirable work.

       D．Because the writer did something she had little knowledge of.

What is the author’s purpose of writing the passage?

       A．To show how you describe your job affects your feelings toward it.
