German scientists say that eating a little chocolate every day may keep you away from cardiovascular(心血管的) disease. The scientists have found that chocolate, especially dark chocolate , can help you cut down 39 percent of heart disease, including taking a very small amount . However, the study advises people not to eat too much chocolate, because too much chocolate is bad for our bodies. So the scientists advise people to eat small amount of chocolate instead of sugar or high-fat snacks.
Scientists said, “Dark chocolate shows the greatest effects, milk chocolate fewer , and white chocolate no effects.” The results showed chocolate may cut down blood pressure, but they also say that further study is needed.
In the eight-year study, people’s daily diet, exercise habits, and blood pressure were studied in 19,357 persons aged 35 to 65. They found that people who are an average of 7.5 grams of chocolate a day had a very lower chance of heart disease than those who ate much less chocolate , and average of 1.7 grams a day.
小題1:It took the scientists __________ years to prove that small amount of chocolate is good for people.
A．8B．35C．39D．65
小題2:In the study, scientists studied _______________.
A．where chocolate came from

My summer hols wr CWOT. B4, we usd 2 go 2 NY 2C my bro, his CF & thr 3:-@ kids FTF ILNY, its gr8.
　　Can you understand this sentence? If you can't, don't feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet or cellphones. To newcomers, it can look like a completely foreign language. So, what is the "translation" of the sentence above? My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love New York; it's great.
　　Schoolteachers and parents say this new form of writing is harming（破壞）the English language. Increasing spelling and grammatical mistakes cxan be seen in students' writing. They fear the language could become corrupted（面目全非的）.
　　Everyone should just relax, say linguists（語(yǔ)言學(xué)家）. They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. "People get better at writing by writing," he says, "Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents."
　　Linguist James Millroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today's teenagers become tomorrow's parents, they too will think this way. Milroy argues that languages do not and cannot become "corrupted"; they simply change to meet the new needs.
　　However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, "I can understand Netspeak worries teachers and it's important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future."
　　Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn't use text language in my homework. Texting is just for fun"
　小題1:What is the main purpose of the first paragraph?
A．To give an example of a foreign language.
B．To show an example of creative methods.
C．To express worries about using Netspeak.
D．To lead in the topic of Netspeak.
　小題2:Which of the following is true according to the passage?
A．Cynthia McVey points out teenagers can deal with Netspeak properly.
B．Geoffrey Nunberg believes Netspeakers can write Standard English.
C．David Crystal thinks Netspeak helps develop the habit of writing.
D．James Milroy says that language is changing and improving.
　　小題3:The expression "bet your bottom dollar" in Paragraph 5 means ______.
A．be fairly sure B．be greatly surprised
C．think it a pity D．find it interesting
　　小題4: What can be the best title for the passage?
A．Netspeak: A Widely-Used Language on Internet
B．Is Netspeak Harming the English Language?
C．Is Netspeak Helpful in Language Learning?
D．Netspeak: Advantages and Disadvantages

Do you know HFMD? It’s short for Hand-Foot-Mouth Disease. This year, in China, thousands of children were suffering from it. What’s HFMD? How to prevent it? Now, read the passage please.
HFMD usually affects babies who are 1~4 years old, but adults can also be infected. Both EV71 and Cox A16 can cause HFMD, which usually starts with a slight fever followed by blisters (水泡) and ulcers (潰瘍) in the mouth and rashes (皮疹) on the hands and feet.
It can be spread through people with the mucus (唾液) or feces (糞便) of an infected person. It usually appears during the summer and autumn months. HFMD isn’t Bird Flu, SARS or Mad Cow Disease, but it’s not a new one, either. It first appeared in New Zealand in 1957. About forty years later, it appears in Asia. It’s reported that it breaks out every 2 or 3 years.
HFMD is very terrible and there is no vaccine (疫苗) now, but we can do something helpful to prevent it. ‘Children with HFMD should seek medical treatment as early as possible’, experts say. They also suggest that parents keep the air fresh in a child’s room, which should be kept clean, tidy and dry. Children should be taught to wash their hands regularly. Staying away from crowded public places is also basic.
小題1: HFMD is usually spread with ____________.
A．fecesB．feces of an infected person
C．waterD．mucus

For hundreds Of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化學(xué)物質(zhì)) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大腦) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
小題1: Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?
A．Weather.B．Actions of others.
C．Personality.D．Age.
小題2:Which of the following is true about vitamin D according to the passage?
A．It is a kind of artificial chemical.
B．It makes us worried by affecting our brains.
C．It is needed by us all to keep fit.
D．It is in the sunlight.
小題3: What can we infer (推斷) from the passage?
A．We feel good when we are in the bright cool weather.
B．We will be happy when we are caught in the rain.
C．All people in Norway and Sweden feel sad in winter.
D．The more vitamin D you have, the happier you’ll be.
小題4:What may be the best title for this passage?
A．Why Do We Feel Sad?
B．The Weather Influences People’s Emotions
C．People Need More Vitamin D
D．We Can Hardly Change the Weather

Germs(細(xì)菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system(免疫系統(tǒng)) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(細(xì)胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

科目：初中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

On the way back from work every evening, more often than not there would be a homeless man standing at the exit of the freeway (快車(chē)道). He looked to be in his late 40s but was probably a lot younger. He had shoulder length straight black hair and a short beard.
Every day after work I would remember to gather any spare change, and put it aside to give to him if I saw him. A feeling of joy would come over me every time I saw him, while coming off the ramp (坡道). So did he. Sometimes the red light would be on for a minute and we would ask each other about our day. His answer would always be the same, “I’m blessed!”
Then one day I was called into my boss’s office and was told that I was being laid off. For the rest of that day all I could think of was “how am I going to provide for my kids as a mother, how am I going to pay rent?”
Needless to say that on my way home that day I was very sad and upset. I didn’t remember to look for my spare change and keep it ready like I usually did. Yet there he was as always, as I turned the ramp. He set his eyes on me, while still smiling and waving at others as usual.
While I was waiting for the red light to turn, he strolled (閑逛) over to my car. He had a big smile. He looked at me straight in the eyes and said, “Today I will give you a dollar.” He then reached into his pocket and pulled out a dollar bill.
You see that day he taught me a valuable lesson more than a dollar bill. No matter what material things are taken from you, no one can take away your choice to be joyful. Every time I’m faced with challenges, I think of the homeless man’s valuable lesson and remember that I am blessed.

B．he wanted to pay back her
