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.
【小题1】To fight A/H1N1 infection, it’s helpful for us to_______ .

Do you love holidays but hate the increase（增长的） weight that follows? You are not alone.
Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.
With proper planning, though, it is possible to con­trol your weight. The idea is to enjoy the holidays but not to eat too much. You don’t have to turn away from the foods that you enjoy. The following suggestions may be of some help to you. 
Do not miss meals. Before you leave home for a feast (宴会), have a small, low-fat snack(小吃). This may help to keep you from getting too excited before de­licious foods.
Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.
Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.
Choose lean meat (瘦肉). Fill your plate with salad and green vegetables.
If you have a sweet tooth, try mints (薄荷) and fruits. They don’t have fat content as cream and chocolate.
Don’t let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess (过多的) calories.

One afternoon, I was out exploring __46__ and saw a new kind of cactus（仙人掌）. I crouched（蹲）down for a closer look. “You'd better not __47__ that”
I turned around to see an old woman.
“Are you new to this neighborhood?” I explained that I was, __48__,new to the entire state．

　　A new study has found that it may be possible to train people to be more intelligent，increasing the brainpower they had at birth.
　　Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）.
　　But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works.
　　The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
　　First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items，monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time.
　　The four groups experienced a half-hour of training daily for 8，12，17 and 19 days，respectively. To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training.
　　The results, published Monday in The Proceedings of the National Academy of Sciences，were striking. Improvement in the trained groups was a lot greater. Moreover，the longer they trained, the higher their scores were. All performers，from the weakest to the strongest，showed significant improvement.
　　“Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops，”he added，“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”
67．The researchers thought the key to improving the intelligence was ______________.
A．memorizing telephone numbers
B．improving working memory
C．training in concentration
D．recalling a card
68．The following aspects of the training help increase intelligence EXCEPT___________.
A．ignoring irrelevant items
B．monitoring ongoing performance
C．managing two tasks at the same time
D．using previous experience
69．When the experiment was conducted，the researchers______________.
A．trained the four groups for the same period of time
B．only made comparisons between the four groups
C．compared the four groups with control groups
D．trained the four groups together
70．By writing the article，the writer intends to ______________.
A．inform the readers of a new study
B．call on people to be trained to increase intelligence
C．prove one’s born brainpower can be improved
D．tell people the improved intelligence will last forever

Of all the areas of learning the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people. “The burnt child fears the fire” is one example. Another  is  the  rise  of despots(独裁者) like Hitler. Both these examples also point out the fact that attitudes come from experiences. In the one case the experience was direct and impressive; in the other it was  indirect  and  cumulative(累积的). The Nazis got certain ideas largely by the speeches they heard and the books they read.
　 The classroom teacher in the elementary school is in a key position to influence(影响) attitudes. This is true partly because children obtain attitudes from those adults who they respect.
　 Another reason is that pupils are often curious about a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who has previously got little knowledge of Mexico, his teacher’s method of dealing with such a unit will greatly affect his attitude toward Mexicans.
　　However, when children go to school with undesirable attitudes, it is unwise for the teacher to change their feelings by praising or scolding them. She can achieve the proper effect by helping them obtain good experiences.
For example, first-grade pupils afraid of policemen will probably change their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way a class of older children can develop attitudes through discussion, research outside reading and all-day trips.
　　Finally a teacher must not constantly show her own attitudes because her influence can be no good if she has personal prejudices(偏见). This is especially true in respect to controversial(引起争议的) questions  on  which  children should be encouraged to reach their own decision as a result of objective analysis(分析) of all the facts.
【小题1】. The passage mainly tells us _____.

A．attitudes affect our actions

B．teachers play an important role in developing children’s attitudes

C．attitudes can be changed by some classroom experiences

D．teachers gradually affect pupils’ attitudes by their attitudes
