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!

A gentle breeze blew through Jennifer's hair. The golden red sun was setting. She was on the beach, looking up at the fiery (火红的) ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.    

The atmosphere relaxed her. After all she had been through, this was what she needed. "It's getting late," she thought, "I must go home. My parents will be wondering where I am."

She wondered how her parents would react, when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.

It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... It all seemed deserted. She couldn't understand what was going on.    

She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: "Dear Ellen, there is some coffee ready. I went looking." Ellen was her mother but－where was she? On the right side of the hallway was her parents' room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn't slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different－she wasn't in her mother's room and she wasn't wearing the old clothes she ran away in. She was in her cozy bed in her pajamas.     

It felt so good being back home. Suddenly she heard a voice, "Are you feeling better now, dear? You know you got us very, very scared."

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.

What can we infer from the conversation between the woman and the recorder at the beginning of the passage?

       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?

       A．curious        B．indifferent    C．puzzled             D．interested

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.

       B．To argue that motherhood is a worthy career and deserves respect.

       C．To show that the author had a grander job than Emily.

       D．To show that being a mother is hard and boring work．

This brief book is aimed at high school students , but speaks to anyone learning at any stage of life.

   Its formal ,serious style closely matches its content ,a school-masterly book on schooling .The author , W .H . Armstrong ,starts with the basics : reading and writing . In his opinion , reading doesn’t just mean recognizing each word on the page ; it means taking in the information, digesting it and incorporating it into oneself just as one digests a sandwich and makes it a part of himself .The goal is to bring the information back to life , not just to treat it as dead facts on paper from dead trees . Reading and writing cannot be completely separated from each other ; in fact ,the aim of reading is to express the information you have got from the text .I’ve seen it again and again ：someone who can’t express an idea after reading a text is just as ineffective as someone who hasn’t read it at all.

Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history. He generally handles these topics thoroughly and equally, except for some weakness in the science and math sections and a bit too much passion regarding history. Well, he was a history teacher---if conveyed only a tenth of his passion to his students, that was a hundred times more than my history teachers ever got across .To my disappointment, in this part of the book he ignores the arts. As a matter of fact, they demand all the concentration and study that math and science do, though the study differs slightly in kind. Although it’s commonly believed that the arts can only be naturally acquired ,actually ,learning the arts is no more natural than learning French or mathematics.

My other comment is that the text aged. The first edition apparently dates to the 1960s—none of the references(参考文献)seem newer than the late 1950s. As a result, the discussion misses the entire computer age.

These are small points, though, and don’t affect the main discussion. I recommend it to any student and any teacher, including the self-taught student.

According to Armstrong, the goal of reading is to________.

A. gain knowledge and expand one’s view

B. understand the meaning between the lines

C. express ideas based on what one has read

D. get information and keep it alive in memory

The author of the passage insists that learning the arts_________.

A. requires great efforts

B. demands real passion

C. is less natural than learning math

D. is as natural as learning a language

What is a shortcoming of Armstrong’s work according to the author?

A. Some ideas are slightly contradictory.

B. There is too much discussion on studying science.

C. The style is too serious.

D. It lacks new information.

This passage can be classified as________.

A. an advertisement

B. a book review

C. a feature story

D. A news report

A new research has uncovered that culture is a determining factor when interpreting facial emotions （情感）．The study reveals that in cultures where emotional control is the standard, such as Japan, focus is placed on the eyes to interpret emotions．Whereas in cultures where emotion is  openly expressed, such as the United States, the focus is on the mouth to interpret emotion．

       "These findings go against the popular theory that the facial expressions of basic emotions can be universally recognized," said University of Alberta researcher Dr．Takahiko Masuda．"A person's culture plays a very strong role in determining how they will read emotions and needs to be considered when interpreting facial expression．"

       These cultural differences are even noticeable in computer emoticons （情感符号）, which are used to convey a writer's emotions over email and text messaging．The Japanese emoticons for happiness and sadness vary in terms of how the eyes are drawn, while American emoticons vary with the direction of the mouth．In the United States the emoticons :） and :-） show a happy face, whereas the emoticons  : （ or : -（  show a sad face．However, Japanese tend to use the symbol （ ' ' ） to indicate a happy face, and （ ;_; ）to indicate a sad face．

       "We think it is quite interesting and appropriate that a culture tends to mask its emotions．The Japanese would focus on a person's eyes when determining emotion, as eyes tend to be quite subtle （微妙的）," said Masuda．"In the United States, where open emotion is quite common, it makes sense to focus on the mouth, which is the most expressive feature on a person's face．"

The text mainly tells us that __________．

       A．cultural differences are expressed in emotions

       B．culture is the key to interpreting facial emotions

       C．different emoticons are preferred in different cultures

       D．people from different cultures express emotions differently

Which emoticon is used by Americans to show a happy face?

       A．（;_;）            B．:-）         C．:-（                D．: （

If a Japanese wants to detect whether a smile is true or false, he will probably_______．

       A．read the whole face  B．focus on the mouth

       C．look into the eyes    D．judge by the voice

People used to believe that _______．

       A．some facial expressions of emotions were too complex to be recognized

       B．people in the world interpreted basic emotions in different ways

       C．people could only recognize the facial expressions of basic emotions

       D．people all over the world understood basic emotions in the same way
