Most animals protect(保護(hù)) their young until they are old enough to take care of themselves. A fish that swims in the rivers of South America protects its young in a very strange way. This fish, a kind of catfish, uses its mouth to keep its babies from danger(危險).
When this catfish lays(產(chǎn)卵) its eggs, it carries them in its mouth. From what we know, it does not eat during this time. After the eggs hatch(孵化), the fish swims with its young to protect them. It opens its mouth when danger appears(出現(xiàn)), and the tiny fish swim inside. They swim out only when it’s safe again.

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

Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(膽固醇) levels.
Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died.
The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first.
小題1: The passage tells us that the new use of aspirin is___________.
A.to treat heart disease.
B.to reduce pain while one suffers from a heart attack.
C.to help old people to be more healthy.
D.to reduce the chance of a heart attack in old men.
小題2:Aspirin can help those who___________.
A.work as doctorsB.a(chǎn)re under 40 years old
C.a(chǎn)re fat and smoke cigarettesD.a(chǎn)re older and healthy
小題3:From the experiment we can conclude that about _________ of people who suffered from heart attacks without aspirin died.
A.7%B.11%
C.19%D.44%

Forests have always been useful and important to men who make use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from the terrible heat. They’re also useful in preventing(阻止) good and rich top soil from being washed away during heavy rains. If there were no forests, heavy rains would wash away the rich surface(表層) soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but men in the past had no enough knowledge about science of nature, and they cut down too many trees in the area where they lived and never planted new ones. By and by, the rich surface soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.
根據(jù)短文內(nèi)容,判斷正(T)誤(F)。
1.Trees are not serving man everywhere.
2.Without trees it would be possible to build houses, boats, bridges and so on.
3.Trees can stop man from the terrible heat.

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.

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

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.
小題1: The writer would have a short conversation with the homeless man when                .

小題3: What is NOT true about the homeless man from the passage?
A.He would be seen at the exit of the freeway.
B.He usually smiled and waved at others.
C.He had a deep impression on the writer.
D.He felt joyful only when money was offered to him.
