A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001.

American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa (ǩ֤) requirements. Now stronger efforts are being made to get more foreign students to study in the United States.

China remained in second place in front of South Korea but behind India, which sent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place.

There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand.

For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University.

Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering.

The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year.

1 After 2002, the number of foreign students in the USA fell mainly because ____ .

A. Americans were worried that foreign students might attack them

B. few American universities welcomed students from abroad

C. their own countries could offer them a better education

D. it was harder for foreign students to get permission to study in the USA

2 Which of the following Asian countries has the largest number of students studying in the USA?

A. China.           B. Japan.           C. South Korea.  D. India.

3 Which subject is the most attractive to foreign students in the USA?

A. Business and management.       B. History.

C. Engineering.                        D. Language.

4We can learn from the passage that ____ .

A. Kenya is the only African country that has students in the USA

B. now foreign students are encouraged to study in the USA

C. the number of students studying in America always increases

D. the number of foreign students in the USA will keep increasing in the future

A new report says only about half of all students in the main school systems of America’s largest cities finish high school. The report notes higher rates of graduation — over 70% —in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation’s fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people.
Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true picture of the number of students who leave high school before finishing.
Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America’s Promise Alliance. The private group aims to help children receive services they need to succeed.
General Colin Powell was chairman of America’s Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future.
Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school.
【小题1】The author wants to tell us ___________.

American beekeeping operations have been hit hard by what scientists call colony collapse disorder(C.C.D.). Almost half of their worker bees have disappeared during the past season. C.C.D. has also been reported in Israel, Europe and South America. Bees fly away from the hive and never return. Sometimes they are found dead; other times they are never found. Many crops and trees depend on pollination （授粉） by bees to help them grow.

A new report says virus may be at least partly responsible for the disorder in honey bee colonies in the United States. This virus is called Israeli acute paralysis virus. It was first identified in Israel in 2004. Ian Lipkin at Columbia University in New York and a team reported the new findings in Science magazine. Doctor Lipkin says the virus may not be the only cause. He says it may work with other causes to produce the collapse disorder.

The team found the virus in colonies with the help of a map of honey bee genes that was published last year. They examined thirty colonies affected by the disorder. They found evidence of the virus in twenty–five of them, and in one healthy colony. The next step is further testing of healthy hives.

The researchers suggested that the United States may have imported the disorder in bees from Australia. They say the bees may carry the virus but not be affected.

The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite（全球性的蜂虱）. This insect attacks honey bees, which could make the disorder more likely to affect a hive. Australian bee producers reject these suspicions.

And some researchers suspect that bee production in the United States is down mainly because of the weather. Honey bees gather nectar（花蜜） from flowers and trees.

American beekeeping operations have been hit hard by what scientists call colony collapse disorder(C.C.D.). Almost half of their worker bees have disappeared during the past season. C.C.D. has also been reported in Israel, Europe and South America. Bees fly away from the hive and never return. Sometimes they are found dead; other times they are never found. Many crops and trees depend on pollination （授粉） by bees to help them grow.
A new report says virus may be at least partly responsible for the disorder in honey bee colonies in the United States. This virus is called Israeli acute paralysis virus. It was first identified in Israel in 2004. Ian Lipkin at Columbia University in New York and a team reported the new findings in Science magazine. Doctor Lipkin says the virus may not be the only cause. He says it may work with other causes to produce the collapse disorder.
The team found the virus in colonies with the help of a map of honey bee genes that was published last year. They examined thirty colonies affected by the disorder. They found evidence of the virus in twenty–five of them, and in one healthy colony. The next step is further testing of healthy hives.
The researchers suggested that the United States may have imported the disorder in bees from Australia. They say the bees may carry the virus but not be affected.
The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite（全球性的蜂虱）. This insect attacks honey bees, which could make the disorder more likely to affect a hive. Australian bee producers reject these suspicions.
And some researchers suspect that bee production in the United States is down mainly because of the weather. Honey bees gather nectar（花蜜） from flowers and trees. The sweet liquid gives them food and material to make honey. But cold weather this spring in the Midwest reduced the flow of nectar in many flowers. Many bees may have starved. Dry weather in areas of the country could also be playing a part.

In recent years, the world has made progress in reducing deaths among children under the age of five. A new report says an estimated 6.9 million children worldwide died before their fifth birthday. That compares to about twelve million in1990.

The report says child mortality rates have fallen in all areas. It says the number of deaths is down by at least 50 percent in eastern, western and southeastern Asia. The number also fell in North Africa, Latin America and the Caribbean.

Ties Boerma is head of the WHO’s Department of Health Statistics and Informatics. He says most child deaths happen in just a few areas.

TIES BOERMA: “Sub-Saharan Africa and southern Asia face the greatest challenges in child survival. More than eighty percent of child deaths in the world occur in these two regions. About half of child deaths occur in just five countries—India, which actually takes twenty-four percent of the global total; Nigeria, eleven percent; the Democratic Republic of Congo, seven percent; Pakistan, five percent and China, four percent of under-five deaths in the world.”

Ties Boerma notes that, in developed countries, one child in one hundred fifty-two dies before his or her fifth birthday. But south of the Sahara Desert, one out of nine children dies before the age of five. In Asia, the mortality rate is one in sixteen.  

The report lists the top five causes of death among children under five worldwide. They are pneumonia, diarrhea, malaria and problems both before and during birth.

Tessa Wardlaw is with the U-N Children’s Fund. She is pleased with the progress being made in Sub-Saharan Africa. The area has the highest under-five mortality rate in the world. But she says the rate of decline in child deaths has more than doubled in Africa.

TESSA WARDLAW: “We welcome the widespread progress in child survival, but we importantly want to stress that there’s a lot of work that remains to be done. There’s unfinished business and the fact is that today on average, around nineteen thousand children are still dying every day from largely preventable causes.”

The World Health Organization says one way to solve these problems is to make sure health care services are available to women. In this way, medical problems can be avoided or treated when identified.

1.Since 1990, the number of the children who died before 5 in the world has dropped by about__________.

A．6,900,000         B．12,000,000        C．1,200,000         D．5,100,000

2. What does the underlined word “mortality” ( in Paragraph 2)mean?

A．illness            B．reduction         C．death            D．problem

3.According to the passage, the readers are likely to believe that __________.

A．child mortality rates have fallen just in five areas

B．Sub-Saharan Africa has the highest under-five mortality rate in the world

C．in developed countries, no children die before the age of five

D．the world has made little progress in reducing the rates of child mortality

4.______ is the top-one cause of death among children under five worldwide.

A．Global warming     B．Malaria           C．Pneumonia        D．Diarrhea

5.What will be probably referred to in the following paragraph?

A．Women do not want to have babies.

B．How more health care services are available to women.

C．Medical problems are completely solved.

D．The World Health Organization.

The United States is facing a growing concern: rising obesity(肥胖) rates. A new report says adult obesity rates rose last year in 23 of the 50 states. And, the percentage of obese children was at or above 30% in 30 states. Mississippi had the highest rate of adult obesity in the new study. 32.5% of the state’s adults were obese. Mississippi also had the highest rate of obese and overweight children. 44.4% of all children between the ages of ten and seventeen years were obese or overweight.

The study used a system of measurement called the Body Mass Index(B-M-I) to define words like obese and overweight. To find your B-M-I, divide your weight in kilograms by height in meters squared. A normal B-M-I is between 18.5 and 24.9. The B-M-I of someone overweight is between 25 and 29.5. And, an obese person has a B-M-I above 30.

The new report says widespread obesity is increasing the rates of long-lasting diseases, such as heart disease. Obesity is also responsible for an increasing part of health care costs in the United States. Health care costs have grown while many Americans are getting fatter. A lack of physical exercise, watching TV too much and eating junk food contribute to the rising obesity rate. The report says the current economic recession(经济衰退) could worsen obesity rates by increasing food prices. This would make healthy foods cost more. The report blames the recession for rising rates of depression, anxiety and stress, which are closely linked to obesity in many cases.

The report offers some ideas for dealing with obesity within government health care reforms. They include making sure that every adult and child has a right to preventive medical services. Also, people should do more physical exercise, drive less and eat less junk food to fight obesity.

【小题1】Since 1990, the number of the children who died before 5 in the world has dropped by about__________.

A new report says only about half of all students in the main school systems of America’s largest cities finish high school. The report notes higher rates of graduation — over 70% —in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation’s fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people.

Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true picture of the number of students who leave high school before finishing.

Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America’s Promise Alliance. The private group aims to help children receive services they need to succeed.

General Colin Powell was chairman of America’s Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future.

Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school.

1.The author wants to tell us ___________.

  A. too many Americans do not finish high school

2. From Paragraph 1 we can infer that __________.

  A. there are 8,360,000 people in the US’ fifty largest cities

B. Wichita in Kansas is the smallest city in the US

C. 50% of the people in the US don’t finish their high school education

D. high school graduation rates in or near the biggest cities are higher

3.The underlined word “picture” probably can be replaced by “_______”.

A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated.
Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.
For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.
The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.  
Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.
The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.
【小题1】It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.
