Although we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.
There are three kinds of flu virus, known as A, B and C. flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies（抗体）which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可变性）is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence（病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters（遇到）. Scientists, however, have a reliable general picture of the world situation.

How do apology languages work? Have you ever tried to apologize, only to be refused? It may be that you were offering a partial apology in a “language”, that was foreign to your listener. The five languages of apology include:
Apology Language 1: “I am sorry.”
List the hurtful effects of your action. Not “I am sorry if …”, but “I am sorry that…”. You might ask if they want to add any points that you have not recognized.
Apology Language 2:“I was wrong.”
Name your mistake and accept fault. Note that it is easier to say “You are right” than “ I am wrong”, but the latter carries more weight.
Apology Language 3: “What can I do to make it right?”
How are you now? How shall I make amends(弥补) to you? How can I restore your confidence that I love you— even though I was so hurtful to you?
Apology Language 4: “I’ll try not to do that again.”
Engage in problem-solving. Don’t make excuses for yourself such as, “Well, my day was just so…” Instead, offer what you will change to prevent yourself from putting them in the same bad situation again.
Apology Language 5: “Will you please forgive me?”
Be patient in seeking forgiveness. They may need some time or greater clarification(澄清) of your input from Apology Languages 1-4.

In order to know a foreign language thoroughly(完全地), four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly with confidence and without hesitation(犹豫). Thirdly, we must be able to write it. We must be able to make sentences that are correct in grammar.
There is no short way to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use learning by heart long lists of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must “Learn through use”. Practice is important. We must practice speaking and writing the language whenever we can.The most important things to learn a foreign language are_______.
| A．understanding and speaking |
| B．hearing, speaking, reading and writing |
| C．writing and understanding |

BEIJING — China’s education authority will tighten the widely criticized policy of “extra credits” for the national college entrance examination to ensure a fairer chance for all exam-takers.
Under the policy, high school students who win awards in national Olympic competitions could get ‘‘extra credits’ up to 20 points for the national college entrance exam. Students with talent in sports and students who are from ethnic groups can also benefit from this policy. The extra credits have increased these students’ chances of being admitted by famous universities. Some parents were found to have helped their children fabricate(伪造)award experiences or falsify qualifications to get extra credits.
“It has harmed education equality，” the ministry said.
Xiong Bingqi, vice-chief of the 21st Century Education Research Institute, said the policy is designed to help students who have special talents but may be weak in academic performance to have a chance to receive higher education. uIt will still be needed but it is time to make the rules fairer," he said.
The ministry said it will reduce the range of competitions whose winners can get extra credits, and limit the winners, privileges(优先权).
The new policy will apply to students who begin high school in 2011, it said.
Chen Lei, a mother of a 10-year-old girl, said she welcomed the ministry's policy adjustment as she does not want her daughter to become an Olympic competition geek.
But not all the Chinese parents welcomed the new policy. “It is like a thunderbolt for me. My - 13-year-old son has spent so much time studying Olympic math，and participated in so many technological competitions during vacations. It is useless now,” said Dong Wen, a 43-year-old mother.
A student said, “Many students have changed the current study plan, and they can abandon the competition. I will be interested in learning the courses which can improve my abilities.”
Yuan Guiren, minister of education, told China Daily that the reform is an attempt to consider the overall quality of an applicant. “But the country will not stop the national college entrance examination as it is still the most objective way to evaluate talent in China，” lie said.It can be inferred from the passage that_____.
| A．high school students with talent in sports are weak in academic performance |
| B．students who win awards in Olympic competitions can’t get extra credits in 2011 |

The koala(考拉) is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia. The word “koala” comes from an Australian aboriginal word meaning “no drink”.
Sometimes people call them “koala bears” but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial(有袋类). Female marsupials have a pouch where the baby animals live after they are born.
Koalas have soft, thick, grey or brown fur on their backs. The fur on the stomach is white. Koala that live in the south have thicker fur than those in the north because of the cold winters, whereas the koalas in the northern part of the country live in warm to hot weather most of the year so have thinner fur. A koala has a large hairless nose and round ears. Koalas don’t have tails. Adult koalas measure between 7 and 14 kilograms.
Koalas spend nearly all their time in the trees using their sharp, curved claws and long toes to climb about and to hold on to the tree branches. They sleep most of the day, and feed and move from tree to tree mainly at night.
The reason koala sleep for much of the day is because their food eucalyptus(桉树) leaves are very tough so they use a lot of energy to digest. Sleeping saves energy. Eucalyptus leaves are poisonous to almost every other animal. Koalas rarely drink water; they get water from the leaves they eat.
Each koala has a home range made up of several trees that they visit regularly. They normally do not visit another koala’s home trees except that a male is looking for a female to mate with.Which of the following statements is NOT true about the name “koala bear”?

| A．The thicker fur can protect them from the colder weather |
| B．It’s always hot in summer in the north |
| C．It’s always cold in the winter in the south |
| D．They have to move to the north in the winter |

Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.Paying students who show improvement in tests __________.
| A．has been done in most American schools |
