A new U.S.government report says more than two million Americans fall ill each year with drug—resistant bacterial infections(感染),and 23,000 of them are dying as a result.The head of the United States Centers for Disease Control and Prevention[CDC]said that the number probably will grow.Officials warn that steps must be taken now to preserve the effectiveness of antibiotic(抗生素)drugs.
Without urgent action to stop that trend,warned Tom Frieden whose agency wrote the report,the miracle drugs to fight them won’t be available in the future.
“If we are not careful,the medicine chest will be empty when we go there to look for a lifesaving antibiotic for someone with a deadly infection.But if we act now,we can preserve these medications while we continue to work on development of new medicines.”The report names a drug—resistant abuse of gonorrhea(淋病),which causes about one quarter of a million hospitalizations in the United States annually.Of the number at least 1 4,000 result in death.
Drug resistance develops through the overuse and inappropriate use of anti—bacterial agents.These can be:doctors prescribing(开药) them to patients who have viral infections that are not affected by medicine meant to fight bacteria;patients not taking all of their medicine as prescribed,so the bacteria making them sick are only weakened,not killed;antibiotic use in healthy farm animals to prevent illness and promote growth.Antibiotic remainders left in meat and animal products can then lead to drug resistance in humans.
To limit the spread of resistant infections,experts recommend wider use of routine immunizations(预防),as well as hand—washing in hospitals and other health care facilities.Also,the report urges hand—washing by food handlers.
Michael Bell,deputy director of the Division of Healthcare Quality Promotion at CDC,said Patients also can play a role in preserving the effectiveness of antibiotics by asking health care providers a few simple questions.
1.What’s the best title of the passage?
A.Drug Resistance Developing Quickly in the US
B.Drug—Resistant Bacterial Infections Growing in the US
C.Actions for Preserving Anti-Bacterial Medications in the US
D.Preventions of Drug-resistant Bacterial Infections in the US
2.According to Frieden,we must take measures without delay to preserve effectiveness of antibiotics,or_____.
A.we will have to develop better medicines in place of antibiotics
B.there may be no effective anti-bacterial drugs for use in the future
C.we can’t find other medicines to cure serious illnesses in the future
D.more and more Americans will suffer from bacterial infections each year

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.
1.It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.
A. climate change B. sea ice’s disappearance
C. seawater’s expansion D. the loss of the Arctic’s ice cover
2. How did the scientists draw the conclusion that sea ice in the Arctic Ocean is melting more quickly than expected?
A. The scientists have been observing the Arctic Ocean for many years.
B. The scientists have compared the computer programs with observation made by satellites and other instruments.
C. The scientists have figured out many numbers with the help of computer.
D. The scientists have found that the seawater take in sunlight and increase temperatures.
3.If the ice melts at the present speed, by the end of this century the ice loss in the Arctic Ocean will be _________ according to newer studies.
A. 22.5% B. 35% C.72% D. 100%
4.Which of the following is TRUE according to the passage?
A. The figures of the computer estimates are wrong.
B. Scientists study climate change through studying sea level.
C. Newer studies show gases may have more effect on sea ice in the Arctic Ocean.
D. The ice is melting even faster than satellites have estimated.
5.This report mainly warns human to _________.
A. prevent the sea ice in the Arctic Ocean from melting any more
B. pay more attention to the loss of the Arctic’s ice cover
C. take necessary steps to protect the environment of our earth
D. stop summer sea ice in the Arctic from disappearing so fast

The world’s population is more mobile (移动的)today than ever before. In 2010, more than 200 million people left their home countries to live in a new country. This is about 3 percent of the total world population. Some experts believe that number will swell to 400 million by 2050. Rates of immigration have remained strong for the last 300 years, but patterns of immigration have changed since World War II. The backgrounds and experiences of today’s immigrants are different from those of the typical European immigrant of the nineteenth and early twentieth centuries. Contemporary immigrants range from unskilled laborers to highly skilled professionals, and they come from and go to countries all over the world.
In the nineteenth century and until World War II, immigration was primarily in one direction- from the Old World to the New World. This is no longer the case. Countries such as Russia and China, which have long been, and continue to be, significant source countries, are now also destination countries. There is also considerable mobility inside regions, such as from one European country to another, or among the countries of the former Soviet Union.
In spite of such differences, the push and pull factors for immigration remain essentially the same as they were 100 years ago. Most people move to another country because they want a better life. For the majority of immigrants, this means better economic conditions. As in past generations, a labor shortage in one country often draws workers from another country, especially if wages are significantly higher. In some small countries, for example, Qatar, United Arab Emirates, and Kuwait, there are more jobs than citizens. The demand for labor is so high that the majority of the population consists of foreign-born workers, ranging from highly skilled engineers and financial experts to domestic and construction workers.
In traditional destination countries, such as the United States, however, labor needs have changed. Today, although there is still demand for unskilled labor, there is increasing demand for people with a high level of skill and education. The need for less skilled labor has shifted to other countries. As work on farms and in industry in the United States and Canada once drew workers from all over the world, now work in factories in Taiwan and south Korea attracts workers from Vietnam, the Philippines, and Cambodia.
Most global immigration is legal: however, a large number of people also move across national borders illegally in pursuit of employment. Experts estimate that about 15 to 20 percent of immigrants worldwide are in their new countries illegally. The United States has the largest number of these immigrants, followed by South Africa, with significant numbers also in Northern and Western Europe and Mexico. These immigrants face particular challenges because they often must hide from the authorities who might deport them back to their home countries. Their illegal status also means that employers may take advantage of them by forcing them to work longer hours and paying them less than the legal minimum wage.
Although economics remains the most important motivation in all forms of immigrant, other factors are also important. Some people decide to leave their home countries because their actions or political beliefs make it dangerous for them to remain. Others choose to leave because their home country has become too dangerous and unstable, often because of war or political unrest. They wish to find a place that is secure for themselves and their families. Education is also a significant factor for many modern immigrants. They want to raise their children in a place where they can get a good education, which, in turn, they hope will provide them with better prospects for the future. Finally, family and community ties also play a role in immigration decisions. As in the past, once a group of people from one country establishes a community in a new country, more people from that country is likely to follow.
The pattern, direction, and rate of immigration may change as the global economy changes. However, as long as life in a new country is more attractive than life in the old country, immigration will continue.
1.According to the reading, what are the patterns of immigration in China and Russia today?
A. Many people leave these countries while many people also immigrate to them.
B. They are major source countries for immigration.
C. They are major destination countries for immigrants.
D. Some people immigrate to these countries but many more people leave them.
2.Why is the percentage of foreign-born workers so high in Kuwait, Qatar, and the United Arab Emirates?
A. These countries pay very high wages, so they attract many foreign workers.
B. There are not enough native-born workers in these countries so they must recruit workers from other countries.
C. It is very easy to immigrate to these countries.
D. These countries are very stable so many workers prefer to go there.
3.Why do some employers sometimes pay illegal immigrants less than the legal minimum wage?
A. Employers know that they will not complain about their wages to authorities.
B.They often do not speak good English.
C. Authorities might send illegal immigrants back to their home country.
D. Illegal workers often cause problems for employers.
4.Which is not the factor contributing to the immigration?
A. Education
B. Political instability
C. Religious freedom
D. Family and community connections

Government statistics recently showed that in the UK, more than 3,000 people a year experience electric shocks in their home. A smaller number of people are killed after contact with power lines outside the home. Electric shocks can cause a person’s heart or breathing to stop, can also cause burns and are potentially fatal. It is essential for people to learn basic first aid techniques to deal with such emergencies.
What to do?
If you are the first person to reach someone who has had an electric shock, don’t touch them!
If they are still holding the appliance that has given them shock (e.g. a hair dryer), unplug it or turn off the power at its source. Under no circumstances will you try to move the appliance with your hand!
If you can’t turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.
The victim must remain lying down. If they are unconscious, victims should be placed on their side. But they should not be moved if there is a possibility of neck or spine injuries unless it is absolutely necessary.
It is essential to maintain the victim’s body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation(恢复呼吸). Keep the victim’s head low until professional help arrives.
If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.
1.What kind of passage is it?
A. An advertisement. B. A horror story.
C. A news report. D. First aid emergency advice.
2.The underlined sentence, “Under no circumstances will you try to move the appliance with your hand!” implies that .
A. you should move the appliance that caused it
B. you should pick up the appliance and turn off the electricity
C. it is very dangerous to touch the appliance with your hands
D. it is unnecessary to unplug the appliance with your hands
3.If you can’t turn off the power, you cannot separate the victim from the appliance or the power source by using _________.
A. a folded newspaper B. a blanket
C. a broom handle D. a chair
4.When a person has got an electric shock, you should .
A. separate the victim from the appliance and let them sit up
B. keep the victim warm and help them breathe again
C. move the victim onto their side if they have got neck injuries
D. keep the victim’s head high until professional help arrives

Mental health experts estimate that depression affects more than 120 million people worldwide. It severely affects the person’s quality of life and, in extreme cases, can lead to people killing themselves. Anti-depressant medicines have been shown as an effective treatment for most patients. But the drugs are unable to help a small number of people with the disorder.
For such person, doctors may suggest deep transcranial magnetic stimulation(经颅磁力刺激), or DTMS for short. In this treatment, patients wear a special helmet connected to a machine. An electric coil(线圈)in the helmet sends out regular waves of electromagnetic energy. These beating sounds produce changes in the brain area responsible for the disorder.
Electromagnetic stimulation(刺激) was first tried to treat depression over 30 years ago. Now, a new generation of wiring can direct the energy on one part of the brain. DTMS starts with daily 20-mimute-long treatments for 20 to 30 days. The patient then returns for treatment two to three times a week for several weeks.
The only side effect is sometimes slight head pain. Aaron Tendler is the chief medical officer of Brains way, the company that makes the machine. He said that it’s hard to say how long the effects of DTMS last.
DTMS is being used in Europe to treat both depression and other conditions. Patients there are getting treated for dementia, Alzheimer’s and Parkinson’s disease. And DTMS is even being used to help some Europeans give up smoking.
But in the United States, the Federal Food and Drug Administration(FFDA) has approved it only for the treatment of depression which cannot be treated by medicine. But clinical tests are continuing on other conditions, such as obsessive-compulsive disorder and post-traumatic stress disorder. Both of the disorders, like depression, can get in the way of a person working and getting along with people.
1.Why are people concerned about depression?
A.Because it may lead to death sometimes.
B.Because only a few people can recover from it.
C.Because it does not affect social communication.
D.Because medicine treatment usually fails to work on it.
2.How does DTMS help patients with depression?
A.By wearing a helmet in daily life.
B.By performing an operation on the head.
C.By making them face the disease bravely.
D.By letting electromagnetic waves stimulate the brain.
3.What can we infer about DTMS from the text?
A.It is quite safe to use it worldwide.
B.The use of it in America is forbidden.
C.It can cure patients of depression in a month.
D.It will be widely used in treating more diseases.
4.What would be the best title for the text?
A.Finding Hope in A Hopeless Depression
B.DTMS - A New Treatment for Depression
C.The Killer of Modern Humans Depression
D.Using Electromagnetic Waves to Cure Depression

Scientists have recently discovered a major habitat where live more than 1.5 million Adelie penguins(企鹅)near the Antarctic Peninsula. Based on direct ground counts and computer counts, the researchers found a total of 751,527 pairs of Adelie penguins on the Danger Islands in the Weddell Sea on the east side of the Antarctic Peninsula. The Adelie penguins discovered here is more than the rest in the other places of Antarctic Peninsula, which was published in the journal Scientific Reports.
Moreover, the number represents the first complete census of Adelie penguins in the Danger Islands, the researchers added. “Until recently, the Danger Islands wasn't known to be an important penguin habitat.” Heather Lynch, an ecologist from Stony Brook University who led the study, said, “These super habitats have gone undiscovered for decades partly because the islands themselves are distant and the dangerous waters that surround them.” The Danger Islands appears to have avoided recent loss in penguin population documented on other parts of the Antarctic Peninsula.
Another study published earlier suggested that more than 70 percent of king penguins may disappear by the end of the century as a result of global warming and overfishing. As the Danger Islands is likely to remain important islands for many penguins under climate change, scientists believe it deserves special consideration in the design of Marine Protected Areas in this area. “Now that we know how important this area is for penguin, we can better move forward designing Marine Protected Areas and managing the fishery,” said Lynch.
The idea of building the Marine Protected Areas, which covers 1.8 million square km of the Weddell Sea and around the Antarctic Peninsula, was first put forward by the European Union and supported by nongovernmental organization Greenpeace. In January, a global campaign has been started in the vast fishing-free zone to better protect wildlife.
1.What can we learn from paragraph 1?
A. Researchers knew the number of penguins only by computers.
B. There are 751,527 pairs of penguins on the Antarctic Peninsula.
C. Researcher may have never been to the Antarctic Peninsula.
D. The Danger Islands may be fit for penguins to live on.
2.What does the underlined word “census” in paragraph 2 mean?
A. Population count. B. Living condition.
C. Birth. D. Desert.
3.Why are there many penguins on the Danger Islands?
A. The Danger Islands is unknown for humans.
B. There is little climate change there.
C. Many people are protecting penguins.
D. The Danger Islands is free from being disturbed by humans.
4.What can we know from what Lynch said?
A. Half of king penguins will die out in the future.
B. The Antarctic Peninsula needn't become Protected Areas.
C. Because the Danger Islands is dangerous, it becomes a super habitat.
D. The number of penguins discovered here is the largest in the Antarctic Peninsula.

Washington, April 4----- The United States has more than 90 million families for the first time, but each contains fewer people on average than ever, the Census Bureau(统计局) reported today.
The 90,031,000 families in the United States averaged 2.64 members each as of last July 1.“The reason is, in effect, changes in the age structure,” explained Campbell Gibson, a population researcher for the bureau. Most Americans born in the great explosion of births are now in their 20’s and 30’s when they most likely to set up families, he said.
The fact that many are doing so increased the number of families from 80.4 million in 1980 t0 88.8 million in 1986 and past the 90 million mark last summer.
At the same time, the average number of people per family dropped from 2.75 in 1985 to 2.65 in 1986 and then to 2.64, Mr Gibson said.
By comparison, the 1970 Census found the average family contained 3.14 people. Families averaged more than four people in 1939 and more than five in 1880.
The growing number of ever---- smaller families is still going on, but Mr Gibson pointed out that family growth was not the same as population increase in the 1970’s.
The same age factors that are increasing the number of families also happened then, but in the 1970’s the proportion(比例) of families in each age group was also growing.
That hasn’t continued in the 1980’s for a number of possible reasons, Mr Gibson said. For example, in the 1980’s more young people have chosen to remain home with their parents instead of setting up housekeeping on their own, as many did in the 1970’s.
This could be caused by the increasing cost of housing, he said. Delays in marriage while young people go to work and school, have also been widely reported as a factor, but it was not the only factor for the family changes.
1.The smaller figure of families reported here is _________.
A.1980 | B.80,400,000 | C.2.64 | D.90 million |
2.What’s the reporter’s attitude towards the present situation?
A. People should get married at later age.
The average number of family members should be 2.64. It’s not clear in the report. Young people should set up housekeeping on their own, as many did in the 1970’s.3.From the last paragraph we may infer that________.
A. delay in marriage will not help the number of the families
delay in marriage is the major factor of the family changes the writer felt sorry that many young people now delay their marriages there must be some other factors which have led to the slower growth in the 1980’s4. The underlined word “factor” in the passage means_________.
A.reason | B.something that proves be true |
C.advantage | D.something that helps to bring about a result |
