Avian influenza (禽流感), or "bird flu", is an infectious
disease of animals was caused by viruses that normally infect 【S1】______
only birds and, less commonly, pigs. Avian influenza viruses are
highly species-specific, but have, on rare occasions, crossed the
species barrier to infecting humans. 【S2】______
In domestic poultry (家禽), infection with avian influenza
viruses cause two main forms of disease, distinguished by 【S3】______
low and high extremes of virulence (毒性). The so-called
"low pathogenic (病原的)" form. commonly causes only mild
symptoms and may easily go undetected. The highly pathogenic
form. is far more dramatic. It spreads very rapidly through
poultry flocks, causes disease affecting multiple external organs, 【S4】______
and has a mortality that can approach 100%, often within 48
hours.
Bird flu is not the same as SARS. Because their symptoms 【S5】______
are similar, SARS is caused by completely different viruses.
Influenza viruses also are more infectious and cannot be as
readily contained as SARS isolating people who have the 【S6】______
infection.
The current outbreak of bird flu is different from earlier
ones in that officials have been unable to contain its spread. An
outbreak in 1997 in Hong Kong was the first time the virus had
spread to people, but it was much more quickly contained. A
total of 18 people were hospitalized with six reporting deaths. 【S7】______
About 1.5 million chickens were killed by an effort to remove 【S8】______
the source of the virus.
Unlike the 1997 scare, this outbreak has spread more rapidly
to other countries, increasing its exposure on people in varied 【S9】______
locations and raised the likelihood that the strain will combine 【S10】______
with a human influenza virus.

Students would learn to schedule time for these chores between their classes and activities. New students are often used 【C16】______ their parents do things for them.

第10题
(33)It doesn't sneak up on you for the first few days, like a cold does. All of a sudden, you feel weak, you have a high fever, you have chills, yon cough frequently and forcefully, your throat is sore, and your body aches.
For most adults, the treatment is to simply wait it out: stay home, get lots of bed rest, drink lots of fluids, and take over-the-counter medications such as aspirin and pain-killers. Symptoms usually go away within two weeks. (34) For the elderly and young, it may become a bacterial infection with deadly consequences, because the victim becomes too weak to battle the disease. The death rate for the general population is about one in 1,000. (34) Those most susceptible to severe effects of the flu are people over 65 and people with chronic heart or lung problems.
Flu season in the US is usually from December to March. (35)The best prevention, of course, is to stay away from infected people. Since that is almost impossible, the next best preventive strategy is to get an annual flu shot. This vaccine reduces the number of people who get infected -- and who die -- yearly.
(33)
A．By getting in caught by a rainstorm.
B．By sleeping with the air-conditioning on.
C．By talking with the infected people.
D．By having a bad ventilation system.
