    CHINESE schools are having a hard time this autumn. The A (H1N1) flu has hit the country as many

students get infected (感染). According to a recent report, more than 42,000 people in China have caught

the A (H1N1) flu. And 96% of the outbreaks (爆发) have happened in schools.

    Students have to check their temperature many times a day. Classes are closed when two A (H1N1) flu

cases are reported within two weeks. Students with flu-like symptoms (流感相似症状) should be sent to

the hospital at once.

    To make things worse, most students will be taking the mid-term exams.

     How can students go on with their study during the time? Schools and students gave us some ideas.

     Wang Feixuan, 14, Xi'an: A class in our grade was suspended (暂停) last week. Teachers recorded

(录像) videos of our classes and put them online for the resting students to download (下载). The suspended

class also had meetings online. The teacher and students chatted in a group online. They could speak and

hear each other's voices.

     Luo Yijing, 13, Shanghai: A girl in my class caught a common flu and got a fever. She had to stay home

for a week. The teacher asked me to help her. Every day when I got home, I'd call her and tell her what the

teacher taught in class that day. When she had problems with homework, she called me too. 

    Jiang Sai, 16, Beijing: Two classes of our grade were suspended. The school put three video cameras and

several computers in our class. If the resting students have the Internet at home, they can connect (连接)

with the computers in our classroom and have classes with us. The resting students and the teacher can see

and hear each other through videos. They can also ask and answer questions.
