A survey basing on 1，000 students found that 80% of senior students sleep
less than nine hours every night．One main reason lies at students' bad habits．
Too much homework is given by school teachers is another main cause．Some students
are absent-minded while doing their homework，and some wasting their after-class time．
The third cause is that some students have to get up earlier on weekday to get toschool that was far away from home．Experts think an amount of homework for the students should be cut down．Beside，teachers should encourage their students makegood use of their spare time．Only in this way can the students improve our study efficiency．

Dear friends.
Good morning! Today l want to talk on you about public morals. Nowadays we can still see some behavior against public morals. Which is often the case, people tend to talk loudly in public places, annoyed others around. Littering rubbish can be seeing everywhere. In an addition, it's common the young sit on the bus while the elderly stand.
Measures must be taken to change this situation. First of all, as student, we should manage our own behavior and help people around us form well habits. Meanwhile, it was necessary for the government and public organizations to encourage people to behave proper.
That's all. Thanks for your attention!
