Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf ther
e lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? There must be some secrets. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until it
s temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists' next research job was clear: find out what in the fish's blood kept it from freezing. Their search led to some really stra
nge things made up of a protein(蛋白质) never seen in the blood of a fish before. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP. What is the text mainly about?
| A．The terrible conditions in the Antarctic. | B．A special fish living in freezing waters. |
| C．The ice shelf around Antarctica. | D．Protection of the Antarctic cod. |
Why can the Antarctic cod live at the freezing temperature?
| A．The seawater has a temperature of -1.88℃. |
| B．It loves to live in the ice-salt mixture. |
| C．A special protein keeps it from freezing. |
| D．Its blood has a temperature lower than -2.05℃. |
What does "glycol-" in the underlined word "glycoprotein" in the last paragraph mean？
| A．sugar | B．ice | C．blood | D．molecule |
Dear Guys,
I’d like to talk to you about the shame you subjected me to last night. Let me first refresh your memory: You, a group of fit, young men, were playing soccer on the field across from my apartment building. I, a better-than-average looking young woman, was walking along the sidewalk with my groceries. That’s when your ball came flying over the fence and landed in front of me.
One of you approached and asked politely if I would throw the ball back to you. Fighting the urge to drop my bags and run screaming down the street, I reluctantly agreed.
Before I continue, let me explain something that I didn’t have a chance to mention last night: I hate sports. More specifically, I hate sports involving balls. This results from my lack of natural ability when it comes to throwing, catching and hitting. I’m bad at aiming too. So you can understand why I’d be nervous at what I’m sure seemed to you like a laughably simple request.However, wanting to appear agreeable, I put my bags down, picked up the ball and, eyes half-shut, and threw it as hard as I could.
It hit the middle of the fence and bounced back to me.
Trying to act casually, I said something about being out of practice, then picked up the ball again. If you’ll remember, at your command, I agreed to try throwing underhand. While outwardly I was smiling, in my head, I was praying, Oh God, oh please oh please oh please. I threw the ball upward with all my strength, terrified by what happened next.
The ball hit slightly higher up on the fence and bounced back to me.
This is the point where I start to take issue with you. Wouldn’t it have been a better use of your time, and mine, if you had just walked around the fence and took the ball then? I was clearly struggling; my smiles were more and more forced. And yet, you all just stood there, motionless.
Seeing that you weren’t going to let me out of the trouble, I became desperate. Memories of middle school softball came flooding back. I tried hard to throw the ball but it only went about eight feet, then I decided to pick it up and dash with ball in hand towards the baseline, while annoyed thirteen-year-old boys screamed at me that I was ruining their lives. Children are cruel.Being a big girl now, I pushed those memories aside and picked up the soccer ball for the third time. I forced a good-natured laugh while crying inside as you patiently shouted words of support over the fence at me.
“Throw it granny-style!” one of you said.
“Just back up a little and give it all you’ve got!” another offered.
And, most embarrassing of all, “You can do it!”
I know you thought you were being encouraging, but it only served to deepen the shame.
Anyway, I accepted your ball-throwing advice, backed up, rocked back and forth a little, took a deep breath and let it fly.
It hit the edge of the fence and bounced back to me.
I surprised myself --- and I’m sure you as well --- by letting out a cry, “DAMN IT!!!” I then willed myself to have a heart attack and pass out in front of you just so I’d be put out of my misery. Alas, the heart attack didn’t happen, and you continued to look at me expectantly, like you were content to do this all night. I had become a sort of exhibition for you. I could feel your collective thoughts drifting through the chain-link: “Can she really not do it? But I mean, really?”
Unfortunately for you, I wasn’t really game to continue your experiment. Three failed attempts at a simple task in front of a group of people in a two-minute period was just enough blow for me for one night. I picked up the ball one last time, approached the fence and grumbled, “Please just come get the damn ball.”
And you did. And thanks to you, I decided at that very moment to never throw anything ever again, except disrespectful glances at people who play sports.

Recently the busiest person on the Internet is absolutely Yuanfang, a fictional figure from the Chinese TV series “Detective Di Renjie”. In the TV series, Li was often asked by Di, “How do you see it, Yuanfang?” Then, the dialogues between them help advance the plot. Now, the casual pet phrase is used as many as 2.5 million times by netizens in a single day, according to statistics.
In fact, it is not the first popular sentence pattern on the Internet. Many other types of popular network words include those evolved from “the slogans of Vancl(凡客网)” and actor’s lines of “The Legend of Concubine Zhen Huan”.
The explosive spread of the sentence “How do you see it, Yuanfang?” again proved the vast power of the network spread. The appearance of a buzzword(流行词) on the Internet may be coincidental, but the spread of numerous buzzwords has started a social and cultural phenomenon. It is more noticeable that the spread is not a deliberate choice but by chance. Usually, everyone has known about it, except the one concerned.
The appearance of buzzwords is resulting from the agreement of netizens. If something is new and interesting enough, it will cause public attention.
The rise of these buzzwords also benefits from their strong “adhesive(粘着的) force”. After analyzing these buzzwords, we find that they have a common character, namely “novel in structure but empty in content”. Therefore, any concrete contents can be added in these buzzwords, creating fantastic results.
Taking the “Yuanfang-style” as an example, its popularity displayed a social mentality of questioning. Although it seems a little funny to ask “Yuanfang”, a fictional character, and some people even find it boring. This way of asking a question reveals a valuable quality-listening. The Internet provides a space for everyone to express their views, but it also causes controversies. What’s your opinion, Yuanfang?We can learn from the passage that Yuanfang.

A new study suggests that sad music might actually arouse positive emotions. The finding helps to explain why people enjoy listening to sad music, say Ai Kawakami and her colleagues from Tokyo University of the Arts and the RIKEN Brain Science Institute, Japan. Ai Kawakami and her colleagues asked 44 volunteers, including both musicians and nonspecialists, to listen to two pieces of sad music and one piece of happy music. Each participant was required to use a set of keywords to rate both their perception(观念) of the music and their own emotional state.
The sad pieces of music included Glinka’s La Separation in F minor and Blumenfeld’s Etude Sur Mer in G minor. The happy music piece was Granados’s Allegro de Concierto in G major. To control the “happy” effect of major key, they also played the minor key(小调) pieces in major key, and vise versa.
The researchers explained that sad music aroused contradictory emotions because the participants of the study tended to feel sad to be more tragic and less romantic than they felt themselves while listening to it.
“ In general, sad music causes sadness in listeners, and sadness is regarded as an unpleasant emotion. If sad music actually arouses only unpleasant emotion, we would not listen to it,” the researchers wrote in the study.
“Music that is believed as sad actually causes romantic emotion as well as sad emotion.And people, regardless of their musical training, experience this ambivalent(矛盾的) emotion to listen to the sad music,” added the researchers.
Also, unlike sadness in daily life, sadness experienced through art actually feels pleasant, possibly because the latter does not cause an actual threat to our safety. This could help people to deal with their negative emotions in daily life, concluded the authors.
“Emotion experienced by music has no direct danger or harm unlike the emotion experienced in everyday life. Therefore, we can even enjoy unpleasant emotion such as sadness. If we suffer from unpleasant emotion aroused through daily life, sad music might be helpful to alleviate negative emotion,” they added. People enjoy listening to sad music because _______.
| A．sad music may help arouse positive emotions |
| B．sad music can make people relax |
| C．Sad music has a positive effect on people’s health |
| D．many experts recommend people to listen to sad music |
We can learn from the passage that _______.
| A．sad music only causes sadness in listeners |
| B．Only musicians were invited to take part in the survey |
| C．The volunteers were asked to listen to three pieces of music in all |
| D．Granados’s Allegro de Concierto in G major can cause positive emotions |
The underlined word “alleviate” in the last paragraph means “ ”.
| A．add | B．strengthen | C．cause | D．reduce |
What is the main idea of this passage?
| A．People should listen to sad music. |
| B．Happy music can make people sad. |
| C．Sad music may actually cause positive emotions. |
| D．Sad music is really bad to people. |
My husband and I had just opened up a pet sitting business earlier that year. Our customers had slowly risen from three to thirty a month. We were busy through those hot summer months, driving between visits. Our services were strictly held at the pet owner’s home. It was almost too busy for the two of us, but we were making good money!
We asked pet owners new to our services to phone two weeks ahead so we had enough time to meet the owners and pets at their homes and make any following meetings before the owner leaves.
One day, we decided to take on a new customer just two days before they would leave. We met the family, filled in a form, and spent some time with their dog, Hercules. He playfully jumped on us and touched our hands and arms using his tongue. The family laughed as he did this, showing us that he was very loving.
Two days later I appeared at the house, alone. I came up to Hercules and said hello happily. I filled up his water bowl and cleaned any messes he made. Meanwhile, he was so lovely sitting beside. I thought this would be the good picture to send to the owners, a usual service. After the light and “click” sound went off, Hercules rushed at me. I didn’t know what had just happened until I noticed the drops of blood. I ran out and did the only thing — calling my husband.
Then I went to neighbors for help. My husband arrived after ten minutes. The helpful neighbor and my husband led Hercules back into his pen (圈). Then my husband and I took off to the hospital.
I must have looked like I was shot when I walked into the hospital. The nurses quickly moved me to a room. I asked the doctor in a weak but playful manner, “ Am I going to die？” He replied, “Finally.”According to the text, the author’s work was .
