London has always been known for its "black fogs". In the winter of 1952, a milky white fog rolled into the city. As the smoke poured into the air, it was so hard to see that people had to walk in front of the buses to guide them. In this way, the most serious air pollution disaster in history began. When it was over, more than 4,000 people had been killed by the thick black smog.
New York City has had several London-type smogs since 1950. Each time, 100 to 400 deaths were caused by the smog. Although these smogs were not as deadly as London's, New York City has the worst air pollution problem in the United States.
In all the killer smogs, factories and homes poured smoke and fumes into the air from the furnaces. The chemical fumes combined with the water droplets in the fog to form harmful substances. These substances caused the illness of those who breathed the polluted air.
Usually, such harmful fumes rise into the upper air and are blown away by the wind. But sometimes there is an unusual weather condition called a temperature inversion. A layer of cold air remains near the ground as smoke and fumes pour into it. This is covered by an upper layer of warm air that acts like a lid. It prevents the polluted cooler air from rising. The harmful fumes pile up and make people ill. The smog may be so thick that airports are closed and chains of collisions occur on the highways.
Another type of smog occurs in Los Angeles. Here the weather may be clear and sunny. But stinging eyes and dry coughs show that harmful chemicals fill the air. The smog is due to invisible gases, mostly from automobile exhaust. Because these chemicals are changed by the sun high up in the air, it is called photochemical smog. It contains automobile exhaust fumes and nitrogen oxides changed by the sun's rays. Added to these are sulfur dioxide and other fumes from factories and oil refineries. Photochemical smog is found in many large cities all over the world.
Killer smogs don't happen very often, fortunately. But in Beijing, a combination of automobile exhaust fumes, home furnace smoke, and factory waste gases pours into the air. This may also happen in the suburbs, or out in the country, where large factories have been built. A number of harmful substances have been found in the air there. When these substances are breathed in day after day, the health of the population is affected.Why do people call this phenomenon "black fog"?

A new Australian research indicates that children with a stutter (结巴) do not suffer disadvantages at school, More than ten percent of children have a stutter by the age of four but they score just as high as other children on tests designed to judge their language, thinking skills and character.
Professor Reilly’s team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress.
By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children.
The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment —which can be expensive — to see if the stutter goes away by itself, unless the children become very unhappy or stop talking.Children with a stutter at school _______.
| A．are poor in their lessons |
| B．have normal language skills |

| D．their children had a symptom of stuttering |
The author shows the result of the research by _______.
| A．presenting some statistics |

Some children may stutter probably because_______.
| A．they become angry very easily |
| B．their intelligence is very poor |

It can be inferred from the last paragraph that _______.
| A．it costs quite a lot to treat children with a stutter |
| B．it is hard for stuttering children to speak normally |
| C．children with a stutter should be treated in a proper way |
| D．stuttering children can’t be any worse off than they are already |
A couple of years ago on a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming hole behind his house. In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks, and shirt as he went. He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator (短吻鳄) was swimming toward the shoe. His mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, shouting to her son as loudly as she could.

A gust of wind blew a canvas chair across the yard. My eyes followed the circling dirt out to the road and down toward the school bus stop. I was going to miss walking down the road to catch the big school bus that took us into town to school. I enjoyed being with the teachers and the other students. Now that I was finished with school I seemed to have lost some of the excitement from my life.
As I was folding the canvas chair, Chatita Chávez drove into our yard in her father’s old truck. It made short loud sounds and sent out a trail of black smoke out of its tailpipe. She got out smiling as usual and excitedly pointed toward the storm that seemed to be moving toward us.
“I can’t stay long, Nilda. There’s a storm coming and I need to beat it home.” I was glad to see her. “Yes, I think we’re in for some bad weather. Come on in and have a cup of coffee at least,” I said as I took her into our kitchen.
“I’m so excited, Nilda! You’ll never guess what I just did!” I stopped pouring the coffee and turned and looked at her.
“I just went over to Edinburg and registered for junior college,” she said and looked at me and smiled. “Don’t you want to go take classes with me?”
I was astonished. I didn’t know what to say. How could I go to college? I didn’t have any money. I gave Chatita a cup of coffee. “I don’t know. I don’t think I can. Isn’t college expensive?”
Chatita sat down at the table and began adding sugar to her coffee. “Not really, and I’m working part-time at the packing shed(棚)on Canal Road. You could work there, too.”
The wind began to gust causing the house to occasionally make sounds and shake. The lightbulb hanging over the table flashed off and on and I heard a low roll of thunder in the distance.
I hesitantly asked, “Do you think I could get a job at the packing shed?”
“Sure. My cousin is the boss. He’ll give you a job.” Mamá came into the kitchen and exchanged greetings with Chatita. She must have heard our conversation.
“I think it’s nice that you’re going to go to college, Chatita. What will you study?” my
mother asked as she joined us at the table.
“I want to be a teacher.”
“A teacher! How nice!” Mamá said as she patted Chatita’s arm.
“A teacher?” I asked. “Don’t you need a degree?”
“You can start teaching before you get your degree. Clarence Duncan has been teaching in Brownsville since last year and I think Zulema will start this year.”
The lightbulb blinked again and went out. Mamá quickly arose from the table. “I’m going to have to bring in the lanterns. I knew I shouldn’t have packed them away.”
“Well, Nilda, do you want to go? Because, if you do, you can go over to Edinburg with me tomorrow.”
I hesitated, then said, “Yes. I want to go.” My heart was beating fast. I couldn’t believe how happy I was feeling.
“But I have to talk to Mamá and Papá. What if they won’t let me?”
“You can at least go with me tomorrow and find out what it’s all about. I’ll come by for you around eight.”
Chatita left me sitting at the table staring at my cup of coffee. It seemed so unreal, this idea of me going to college. My parents had never had the opportunity for much education. Juana had quit school to get married and Roberto and Zeke had graduated from high school as I had. But college? I would be the first one in my family to go to college. Yes, college was exactly what I wanted.
The day had turned dark and the rain had started. My mother came back into the kitchen with two lanterns.
“Mamá, I need to ask you something.”
She picked up a cloth and began to clean the dust from the lanterns. She looked at me and smiled.
“Mamá, if I could find a way to pay, could I take classes at the junior college?” I asked, trying to control my excitement.
She stopped cleaning and raised her eyebrows. “What would you study, my daughter?”
“I think I want to be a teacher,” I quietly replied.
Mamá sat down at the table across from me. “Then, I would like for you to go to college,” she said in a serious tone.
“What about Papá? Do you think he will allow me to go?”
“Your father wants you to be happy. If going to college and being a teacher makes you happy, then he will probably allow it,” she answered.
I didn’t say anything. I was enjoying the feeling of happiness and sense of wonder that had come over me. The two of us sat in the darkened room without speaking until I saw my mamá rubbing her eyes with the edge of her apron.
“What’s wrong, Mamá.”
“Nothing,” she replied. “I probably got some dust in my eyes. That’s all.”This story is told from the point of view of___________.
| A．Chatita | B．Mamá | C．Nilda | D．Papá |
Chatita responds to Nilda’s hesitancy about going to college with___________.

| C．worried her husband will stop Nilda from leaving |

| A．She picks up a chair from their yard. |
| B．She seeks their approval to go to college. |
| C．She sits with her mother without speaking. |
| D．She tells her mother she plans to become a teacher. |

| B．“I haltingly asked, ‘Do you think I could get a job at the packing shed?’ ” |
| C．“ ‘Mamá, if I could find a way to pay, could I take classes at the junior college?’ ” |
| D．“I was enjoying the feeling of happiness and sense of wonder that had come over me.” |
I learned a long time ago that hair has meanings—plenty of meanings. Growing up in the 1960s, my friends and I struggled without parents’ control over the length and style of our hair.
At the time, hair represented our need to break free from adults in our lives. Long hair represented our freed inner selves.
My clients are often surprised when I asked them questions about their hairstyle—why they choose it, how else they’ve worn their hair, how they feel about it, and so on. However, while it may seem to be a simple topic, even today our hairstyles still have many psychological and emotional meanings. Understanding some of those meanings can lead to understanding of many different aspects of a person’s mind. How we view our hair, for example, can show something about how we view ourselves.
Our hair can show physical and emotional wellbeing, desirability, and even social and financial status. When it becomes dull or fragile, it can communicate emotional and physical diseases. But hair can also show unrecognized and often unspoken daydreams about oneself and one’s world. One woman—a successful professional—wore her long hair in a thick bun(发髻).
But one day she showed me that tangled(缠结的) hair was kept in the bun. She said that she never brushed out the tangles because the hair showed her secret image of herself as a helpless, disturbed woman, like Ophelia in the play Hamlet.
Another woman came to therapy in a huge shirt and huge pants that she believed they could hide the weight she had put on since the birth of her child. She talked about how much she hated her body and how helpless she felt about doing anything about it. But her hair was always beautifully coloured and decorated. When I pointed out that she seemed to have a different relationship with her hair from she did with her body, she said that her hair had been thinning and that she was trying to make it look as good as she could. I pointed out that what she was doing with her hair and her body was kind of contradictory, and wondered if she had any thoughts about that.
She was surprised. But as we talked about her contradictory attitudes towards different parts of her physical self, we began to open up all sorts of other thoughts and ideas about her inner self.
And interestingly, as we continued opening those internal doors, changes started to happen. She started eating differently and exercising regularly. One day some months later, she appeared in my office in skinny jeans and a tight sweater, and her hair was pulled back in a ponytail. “I decided to see what would happen if I stopped trying to hide myself, ” she said with a big smile.
“And…? ” I asked. “People keep smiling at me in the street. My husband hugged me this morning for the first time in ages. And I feel good! ”
Besides, selfrespect in both men and women can be damaged by thinning hair；they may feel alone even though they are really not. Given our cultural focus on physical appearance, youth, and health, hair loss can be unpleasant for both men and women. The market is filled with hairenhancing treatments, but there are those who have decided to be against the system and change to the “bald is beautiful” position. But it is much harder for women to take the “bald is beautiful” approach to hair loss. We tend to try to hide it in one way or another.
But no matter what approach you use, it is important to remember that the thickness of your hair has nothing to do with your value in the world. Remember that you have nothing to be ashamed of if you have thinning hair. Thinning hair may not be something you can change, but it doesn’t have to control how you represent the person who lives underneath it.In the 1960s, long hair represented___________.
