As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune
system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
—————————————？
Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.

Providing small classes for at least several grades starting in early primary school gives students the best chance to succeed in late grades, according to groundbreaking new research from a Michigan State University scholar.
The research by Spyros Konstantopoulos, a professor of education, is the first to examine the effects of class size over a period and for all levels of students. The study appears in the American Journal of Education.
He is also a member of a group for the Department of Education’s Instiute of Education Sciences that will give official advice on class size to the states. He said the advice will mirror his research: the best plan is to provide continuous small classes(13 to 17 students) for at least several years starting in kindergarten or first grade.
“For a logn time states thought they could just do it in kindergarten or first grade for one year and get the benefits,” He said. “I don’t believe that. I think you need at least a few years in a row where all students, and especially low-achievers, receive the treatment, and then you see the benefits later.”
His research used data from the Project Star study in Tennessee that analyzed the effects of class size on more than 11,000 students in primary and middle school. He found that students who had been in small classes from kindergarten through third grade had actually higher test scores in grades four through eight than students who been in larger classes early on.
Students from all achievement levels benefited from small classes, the research found. “But low-achievers benefited the most, which narrowed the achievement gap with high –achievers in science, reading and math, ” he said.
Although the study didn’t consider classroom practices, he said the reason for the narrowing gap is likely due to low-achieving students receiving more attention from teachers.
“This is especially important in poorer schools because teacher effectiveness matters more in schools with more disadvantaged and low-performing students, ” he said.
小题1:The professor argues about ________ .| A．the size of the class | B．the period of the class | | C．the attention from teachers | D．the achievements of students |
小题2:The result of the research shows that _________.| A．small classes for one year in early grade are enough | | B．continuous small classes help students achieve more | | C．it’s best to attend small classes in kindergarten | | D．small classes do equal good to students of all levels |
小题3:What can we infer from the passage?| A．High achievers will not benefit from small classes. | | B．Continuous small classes have not been widely accepted. | | C．Low-achievers should be separated from high-achievers. | | D．Teachers’ attention matters less than classroom practices. |
小题4:The underlined word “This” in the last paragraph refers to _______.| A．the gap between low and high achievers | B．continuous small classes | | C．classroom practices in later grades | D．the Project Star Sturdy |

Students who say they never or hardly ever used dictionaries often speak English well but usually write poorly, because they make many mistakes.
The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.
The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables (音节), they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionar y.
小题1: The writer thinks that .| A．choose a good dictionary, and you’ll be successful in learning English | | B．dictionaries are not necessary to the students who learn English | | C．it is very important for students to use good dictionaries properly | | D．using dictionaries very often can’t help to improve writing |
小题2:According to the passage, which of the following is wrong?| A．Dictionaries have little effect on learning to speak English. | | B．Whatever new words you meet while reading, never use dictionaries. | | C．Small two-language dictionaries have serious defects (缺陷). | | D．Reading something for the first time, you’d better not use dictionaries. |
小题3:When in the reading does the writer advise students to use a good dictionary?| A．At the beginning of the reading | B．At the end of the readi ng | | C．During the first reading | | D．After the first reading |
小题4:This passage mainly tells us .| A．students shouldn’t use small two-language dictionaries | | B．what were the defects of small two-language dictionaries | | C．why students should use large college edition dictionaries | | D．what dictionary students should choose and how to use it |
小题5: Which is not mentioned in this passage?| A．How to make good use of a dictionary. | B．When to use a dic tionary. | | C．How to improve spoken English. | | D．How to practise reading fast. |

There is no excuse for not doing your assignments（作业）. If you can’t come to school, you should call your teacher or your classmate and ask about homework. It is your responsibility（责任）to find out what homework you have missed. It is not the teacher’s job to remind you of the missed assignments.
You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows a make-up test（补考），you should take the test within one or two days after you return to class. Serious illness is the only reason for missing a test.
Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the room. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late.
In America, you should call your teacher by his or her last name instead of “ teacher”. Also you should use Mr, Miss, Ms or Mrs before the last name ( such as Mrs Smith or Mr Jones). This is polite. The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don’t do these until the break. Also, removing your shoes in the classroom is not polite.
小题1:What should you do if you miss a class?| A．Give an excuse for missing the assignments. | | B．Tell the teacher you can’t come to school or do the assignments. | | C．Ask your teacher to remind you of the missed assignments. | | D．Call your teacher or your classmate to find out what assignments were given. |
小题2: When can a student miss a test according to the passage?| A．When he / she is late for the test. | | B．When he/ she is really sick. | | C．When he / she failed another test. | | D．When he / she doesn’t want to have the test. |
小题3: In America, if your teacher’s name is Susan Black, what should you call her politely?| A．Ms Black | B．Ms Susan | C．Susan Black | D．Teacher Black |
小题4:Which of the following is NOT true according to the passage?A．A student is thought to be impolite when he / she takes off his / her shoes in
the classroom. | | B．A student is thought to be impolite when he / she eats and drinks in class. | C．When a student is late for class, he / she must knock before he / she enters the
classroom. | | D．A student is thought to be impolite when he/she doesn’t come for class on time. |
