Boris Worm of Dalhousie University in Nova Scotia, Canada, led the international team that did the study. Professor Worm says species have recently been disappearing from oceans at increasing speed. At this rate, he says, all seafood species could collapse by 2048 and seafood supplies from the world’s ocean could be almost gone by then.
Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty in fifty years. Some scientists said parts of the world do have problems, but others are doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
The study appeared earlier this month in Science magazine.
The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appeared to increase the risk of fish kills and beach closures from harmful algae growth.
The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization for nineteen fifty to two thousand three. And they examined archeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
Boris Worm says the findings were, in his words, "beyond anything we suspected." But he also said the situation is not too late to correct. He said that with good fisheries management, some species could completely recover in three to ten years.
小题1:Which of the following isn’t the damage to the ocean?     
A.The species of fish in the ocean are reducing.
B.Sea water is polluted.
C.Sea water quality is improved.
D.Less productivity of ecosystem.
小题2:The conclusion of the research led by Boris Worm is _________. 
A.unbearableB.unbelievable

A.was conducted by scientists from Canada
B.referred to information of many countries
C.lasted from 1950 to 2003
D.referred to records dating back to over 1,000 years ago.
小题4:Which of the following statements is NOT true?      
A.It’s too late to take action to improve the situation.
B.Some species will recover with efforts.
C.Boris Worm hopes that people take the warning serious.
D.Boris Worm shows great concern about ecosystem.

Colleges may try to do a lot to prepare students for study abroad – telling about culture shock, warning about homesickness, recommending books about the country. But when it comes to adjusting to campus life when they return, schools haven"t done as much, even though the transition is sometimes almost as difficult.
"They can feel disoriented and depressed. They find things are not exactly the way they were when they left," said Antonio Jimenez, director of the Center for International Affairs at California State University Channel Islands in Camarillo, California, US. "They find that people don"t care much about their experiences."
Some colleges are now rethinking their approach to study abroad, recognizing that students might need almost as much help adjusting to life back home as they did getting ready to leave: students experience a sort of reverse culture shock when they return to the US.
They might be troubled by the wealth and waste they see back home or they might feel homesick for their new country and its customs. And when they try to talk about their experiences, people quickly lose interest, especially if they haven"t lived abroad themselves.
Down the road, they also might find it difficult to translate their time abroad into experience that an employer finds attractive.
Some California universities have organized conferences to help students make the most of their time abroad. During a one-day event, students learn how to adjust after living abroad, talk about their experiences and incorporate them into their lives and future careers.
Blythe Cherney, 22, a senior who has studied in Thailand and Britain, found the workshops helpful.
"Any experience abroad does have an effect on you," Cherney said. "When you come back, it"s important to talk about it, especially with people who know what you"ve been through."
Yet most universities focus more on preparation than reorientation. When students return, they might have a welcome home reception. But for the most part, universities figure students can fend for themselves.
小题1:Which of the following is NOT the trouble that students face when they return from studying overseas?  
A.Culture shockB.Homesick for their new country
C.Losing interest in their homelandD.Difficult transition
小题2:The wrier is _________ the help colleges offer for the students when they return from studying overseas?   
A.pleased withB.dissatisfied with
C.indifferent withD.proud of
小题3:The underlined word “workshops” refers to _________.   
A.conferences where people share their experiences
B.buildings where machines are made
C.shops where books are bought
D.labs where experiments are conduct
小题4:After the students come back_________.                
A.They will easily find a good job.
B.People are very interested in their experiences.
C.They have to waste time and money.
D.They are confused and disappointed.
小题5:What is the passage mainly about?     
A.Overseas students experience culture shock in foreign countries.
B.Some universities offer to help students in need.
C.Returned students find it difficult to translate their time abroad into experience.
D.Returning from studying overseas, students face more trouble than they expected.

Years ago, if a teenager had some problems in her life, she might go home and write in her diary. Now, a teenager with   36  problems might go onto the Internet and write about his problems in a blog. In many ways a diary and a blog are very   37  . So, what makes blogging different from writing in   38  diary?
The biggest difference is that blogging is much more   39  than a diary. Usually, a teenager treats his diary like a book full of   40  that she does not want to   41 .
It’s interesting that someone who writes in a blog   42  a diary will probably write nearly the same information.
I have a little sister, and sometimes I go online to read her   43  . She writes about things like waking up early for swimming practice and not studying enough for her chemistry test.   44  I was her age, I wrote about the same things, but   45  in my diary. Then, after I had finished writing, I would hide my diary in a secret place because I was   46  that my sister might read it!
The biggest   47  with blogging is that anyone can read what you write. If I was angry with a friend during high school and wrote something   48 about her in my diary, she would never know!   49 , if my sister ever wrote something bad about a friend, that friend   50  read her blog and get a “cry”.
There are also   51  to blogging, of course. If I felt sad one day and wrote in my diary: “Nobody cares about me.”  52  would know about it. However, if my sister wrote the same sentence in her blog, her best friends would   53  respond and tell her how much they   54  her. Blogs help people   55  in touch with their friends and know what the people around them are doing.

Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment which are some of the reasons why the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, making it hard for heat energy to go into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
小题1:What is mainly talked about in this passage?
A.The melting of glaciers.B.Global warming.
C.The world’s weather.D.The earth’s temperature.
小题2:What causes global warming according to scientists?
A.Human activities.B.The nature itself.
C.The earth’s atmosphere.D.New discoveries
小题3:How can greenhouse gases make the globe warm?
A.They keep heat in the atmosphere.
B.They let the heat go out into space.
C.They release heat into the air
D.They can make the other gases warm.
小题4:From the passage we can see that global warming will bring about _____.
A.the pollution in the atmosphereB.natural disasters
C.population pollutionD.the rise of glaciers

What is most likely to affect your success at school or at a job? The ability to read. And that goes for your kids too. The declining literacy(读写能力的下降) of our society has been a main concern of educators for a while now, and yet things are not getting better.
In most cases, how well we learn to read will depend largely on our exposure(接触) to language as children. If we hear people around us talking about all kinds of subjects as children, we naturally pick up the words and phrases they use. If we pick up a lot of words, we will learn to read better.
Much of the traditional advice to struggling readers, theses days, seems to include developing “cognitive strategies”(认知策略). In this way, readers are asked to centre more, to think, to be interested and ask questions, to analyze, to predict, to reason, and to check their understanding, or worse still to answer questions of what they have read. In other words they are asked to become self-conscious(有自我意识的) readers. I do not agree with this approach.
Here are my several strategies for reading improvement.
Read about things that interest you. If you are interested in what you are reading about, the words will come alive, and you will understand better. The more you read, the better you will become at reading. Just get started and it will become a habit, as long as you are interested in what you are reading.
Read material that is at your level or just a little difficult for you. Read material that you find easy to read, or just a little challenging. Looking up many unknown words in a dictionary is dull, and the results of the dictionary search are quickly forgotten.
_____ If you can hear the new words and phrases that you are reading, you will have an easier time understanding and remembering them. Hearing the rhythm of someone reading a text will help your own reading.
Don’t worry about what you don’t understand. Most of your reading should be for pleasure. You can still enjoy reading without understanding all of what you read. You may even understand some things in your own personal way.
Unfortunately not all reading is just for pleasure. When you are reading a textbook or report or other material for school, you may need to underline, take notes and read some parts over again. However, if you have developed the habit of reading for pleasure, you will find that the skills you need will come naturally, and that you will understand a lot better than before.
小题1:In Paragraph 2, the author tells us the importance of _____.
A.hearing people around as childrenB.talking ability as children

小题2:Which sentence is best to be filled in the blank in the passage?
A.Listen as much as possible.B.Try to use your imagination.
C.Great works need to be read out loud.D.Listen first if you have trouble reading.
小题3:It can be learned from the last paragraph that _____.
A.you should find pleasure from reading a textbook
B.the habit of reading for pleasure is important
C.reading for school is helpful for reading for pleasure
D.reading for school requires different skills from reading for pleasure
小题4:What is the purpose of the author in writing the passage?
A.To tell us some ways to improve reading ability.
B.To show that poor literacy has been a big problem.
C.To teach us how to look for fun in reading.
D.To tell us some ways to pick up new words and phrases.

About 45 percent of Americans don’t get enough sleep, according to a recent survey. However, the benefits of getting enough sleep far outweigh the thrill of watching TV for one more hour or surfing the web. Getting a better night’s sleep will help you lose or keep your weight more effectively. Try these simple steps to improve your quality of sleep.
Take time to relax
So many of us go-go-go until it’s time for bed, but it’s important to take time to slow down and relax before sleeping. Do relaxing things, such as listening to soothing (抚慰的) music or deep breathing. Avoid stimulating (刺激的) activities such as writing e-mails, talking on the phone and watching TV. Some guidelines (指导方针): no e-mail after 8 p.m. and no TV or phone calls after 9 p.m..
Darker is better
Your body regulates your sleep cycle in response to the presence and absence of light, so dim the lights as evening approaches. Try getting ready for bed by candlelight. When you’re ready to sleep, make sure your room is as dark as possible.
Put your thoughts to bed
We all need time to process our day, but bed is not the place to do it if you want to sleep well. Take 10 to 15 minutes to record your thoughts in a journal. This effective technique will capture what’s in your mind so you don’t lie awake. Tell yourself you’re putting your thoughts to bed so that you can go to bed.
No sugar or alcohol before bed
These may wake you up. If you need a snack before bed, make it protein.
Try to get more sleep
Get an extra hour or two of sleep every night for a week and see how you feel. You’ll notice the difference!
小题1:The purpose of writing this text is to ________________________.
A.share some ways to slow down and relax before sleeping
