There are thousands of coral reefs(珊瑚礁) in the world; Unfortunately, however, they are now in serious danger. More than one-third are in such bad shape that they could die within ten years. ?? 1.?? Here are the three main causes discovered.

The first cause is pollution on land. The pollutants run with rainwater into rivers and streams, which carry the poisons into the ocean.?? 2.?? So they will be easily infected(感染) with diseases.

? 3.?? Higher ocean temperatures kill the important food source(来源) for the coral—the algae, the tiny greenish-gold water plants that live on coral.?? 4.?? This process has happened more and more frequently in recent years.

The last factor contributing to the disappearance of coral reefs is people. People sometimes crash into reefs with their boats, breaking off large blocks of coral.?? 5.??? Moreover, some people even break coral off to collect for souvenirs since it is so colorful and pretty.

A. Global warming is another reason.

B. Many might not even last that long!

C. Divers who walk on reefs can also do serious damage.

D. Reefs provide a home for 25% of the fish in the ocean.

E. Chemicals from the poisons kill reefs or make them weak.

F. Steps must be taken now to stop over-fishing and pollution of the oceans.

G. When the algae die, the coral loses its color and it also dies in the end.

All areas of the world face a nurses shortage. But the shortage is most severe in developing countries. Many of their nurses move to the more developed nations for better pay, better working conditions and better chances for career development. For example, nearly 2,000 nurses left the Caribbean between 2002 and 2006.

       The Caribbean nations currently have about 1 nurse for every 1,000 people. The ratio(比例) of nurses to population is about 10 times higher in the United States and countries in the European Union(EU). Now, more than 21,000 nurses who trained in the Caribbean are working in the United States, Canada and Britain.

       Gaetan Lafortune is an official of the Organization for Economic Cooperation and Development(O.E.C.D) in Paris. He says the nurses shortage also affects industrialized countries. He says, “There is concern in most O.E.C.D.countries that the number of nurses is too small to meet the demand. And what is more worrying is that their concern is sort of growing.” Mr Lafortune says a large number of nurses are expected to retire within the next 10 years. At the same time, the health care needs of aging populations are expected to grow, intensifying the shortage of nurses.

       Gaetan Lafortune said, “In the U.S., for instance, some researchers have found that there may be a shortage of close to a million nurses by 2020.” The United States is 1 of the 21 countries in the O.C.E.D. Gaetan Lafortune says in the recent years many of the countries increased their efforts to hire foreign nurses. As a result of that, O.E.C.D. countries were mainly exporting their shortage problem to countries that may have an even greater need for these nurses.

1.What will be the main causes of the global nurses shortage in the next 10 years?

       a. The demand for nurses will decrease.                    

b. Many nurses will be too old to work.

       c. Many rich countries will hire more foreign nurses.

       A. refuse to offer equal pay to foreign nurses

       B. have at least one nurse out of 100 people

       C. don’t like to train nurses of their own countries

       D. have more serious nursing problems than the Caribbean nations

4.What does the text mainly tell us?

       B. The different attitudes towards nursing in different countries.

       C. Nurses shortage will result in serious consequences.

       D. The health care industry needs more nurses.

An old problem is getting new attention in the United States—bullying．Recent cases included the tragic case of a fifteen-year-old girl whose family moved from Ireland．She hanged herself in Massachusetts in January following months of bullying．Her parents criticized her school for failing to protect her．Officials have brought criminal charges against several teenagers．

Judy Kaczynski is president of an anti-bullying group called Bully Police USA．Her daughter Tina was the victim of severe bullying starting in middle school in the state of Minnesota．She said, "Our daughter was a very outgoing child．She was a bubbly personality, very involved in all kinds of things, had lots of friends．And over a period of time her grades fell completely．She started having health issues．She couldn't sleep．She wasn't eating．She had terrible stomach pains．She started clenching her jaw and grinding her teeth at night．Didn't want to go to school．"

Bullying is defined as negative behavior repeated over time against the same person． It can involve physical violence．Or it can be verbal — for example, insults or threats．Spreading lies about someone or excluding a person from a group is known as social or relational bullying．

And now there is cyberbullying, which uses the Internet, e-mail or text messages．It has easy appeal for the bully because it does not involve face-to-face contact and it can be done at any time．

The first serious research studies into bullying were done in Norway in the late 1970s．The latest government study in the United States was released last year．It found that about one-third of students age twelve to eighteen were bullied at school．

Susan Sweater is a psychologist at the University of Nebraska-Lincoln and co-director of the Bullying Research Network．She says schools should treat bullying as a mental health problem to get bullies and victims the help they need．She says bullying is connected to depression, anxiety and anti-social behavior, and bullies are often victims themselves．

From the case of Tina, we can know that            ．

         A．bullying is rare                     B．victims suffered a lot

         C．schools are to blame                   D．personalities are related

Which of the following is NOT bullying?

         A．To beat someone repeatedly．                  B．To call someone names．

         C．To isolate someone from friends．  D．To refuse to help someone in need．

Why is cyberbullying appealing to the bully?

         A．Because it can involve more people．      B．Because it can create worse effects．

         C．Because it is more convenient．               D．Because it can avoid cheating．

According to Susan Sweater,           ．

         A．bullies are anti-social                            B．bullies should give victims help

         C．students are not equally treated      D．bullies themselves also need help

Which of the following can be the best title of the text?

         A．Bullying—Old Irish Girl Committed Suicide

         B．15-Year-Old Irish Girl Committed Suicide

         C．Cyberbullying-Taking Off in Schools  

D．How to Find Bullying among Teens

The amount of carbon taken in by growing plants increased from 1982 through 1999 as

temperatures rose and the amount of carbon dioxide in the atmosphere increased. But a new study

in Friday ’ s edition of the journal Science found a drought - related decline in such plant growth

from 2000 to 2009，even though temperatures continued to climb.

As drought caused by warming reduces the land ’ s ability to take in carbon，the result could

be more carbon dioxide left in the atmosphere，and thus more warming，Zhao Maosheng from the

University of Montana explained in a telephone interview.

“This is a pretty serious warning that warmer temperatures are not going to endlessly improve

plant growth ’” co - author Steven Running，also from the University of Montana ’ said in a

statement. “ We see this as a bit of a surprise，and potentially significant on a policy level because

previous interpretations suggested global warming might actually help plant growth around the

world, “ he said.

Instead, he and Zhao found a small but measurable decline of about 1%，compared to a 6%

increase in the past decade.

Their study，based on the data collected by NASA satellites，found that north areas continued

to increase plant growth，thanks to warmer temperatures and a longer growing season.

Someone commented, "This past decade’ s net decline in earthly productivity suggests that a

complex relationship between temperature, rainfall, cloudiness, and carbon dioxide, probably in

combination with other factors such as nutrients (营养）and land management，will determine

future patterns and trends in productivity.，^，

1.From the first paragraph, we can learn in the recent decade or so.

A.     the emission(排放)of carbon hasn’ t been reduced

2.Zhao Maosheng really worried that__ .

E.      more and more land will be abandoned

F.     the climate becomes warmer and warmer

G.    the emission of carbon dioxide increases

H.    draught further reduces the number of the plants

3.Steven Running made his statement to__ .

I.       confirm Zhao' s views on the influence of temperature rise

J.      urge the government to take necessary measures

K.     warn the people to strengthen the plant protection

L.     support Zhao* s views on lhe plant production

4. We can infer from the passage that______ .

A.     global warming will determine the future productivity

B.     various factors play a key role jointly on future productivity

C.     earthly productivity actually increased in the past decade

D.     temperature rise has had no effect on future producticity patterns

Sons who have fond childhood memories of their fathers are more likely to be emotionally stable（稳定的） in the face of day-to-day stresses, according to psychologists（心理学家） who studied hundreds of adults of all ages.

“As our study shows, fathers do play a unique（独特的） and important role in the mental health of their children much later in life,” Psychology professor Melanie Mallers of California State University said.

For this study, 912 adult men and women between the ages of 25 and 74 completed short daily telephone interviews about that day’s experiences over an eight-day period. The interviews focused on the participants’ psychological and emotional distress (i.e., whether they were nervous, sad, etc.) and if they had experienced any stressful events that day.

The participants were also required to answer questions such as, “How would you rate your relationship with your mother during the years when you were growing up?” and “How much time and attention did your mother give you when you needed it?” The same questions were asked about fathers.

People who reported they had a good mother-child relationship reported three percent less psychological distress（忧虑） compared to those who reported a poor relationship, according to Mallers.

Men who reported having a good relationship with their father during childhood were more likely to be less emotional when reacting to stressful events in their current daily lives than those who had a poor relationship, according to her findings.

Also, the quality of mother and father relationships was significantly associated（有关） with how many stressful events the participants faced on a daily basis. In other words, if they had a poor childhood relationship with both parents, they reported more stressful incidents over the eight-day study when compared to those who had a good relationship with their parents.

Mallers theorized why healthy or unhealthy relationships may have an effect on how people handle stress as adults. “Perhaps having caring parents equips children with the experiences and skills necessary to more successfully navigate（导航） their relationships with other people throughout childhood and into adulthood.” She said.

  B Men with a good mother-child relationship were more likely to be emotionally stable when reacting to stressful events.

  C Women were better at getting along with their parents than men when they were young.

  D People with good childhood relationships with parents suffered（遭受） fewer stressful incidents.
