The students' answers ranged（范围） from 20g to 500g .

"It does not matter on the weight itself .It depends on how long you hold it .If I hold it for a minute ,it is OK. If I hold it for an hour ,I will have an ache in my right arm .If I hold it for a day ,you will have to call an ambulance（救护车）.It is exactly the same weight ,but the longer I hold it ,the heavier it becomes."

"If we carry our burdens （负担）all the time, sooner or later ,we will not be able to carry on ,the burden becoming increasingly heavier ."

"What you have to do is to put the glass down ,rest for a while before holding it up again ."

ORLANDO, FLORIDA — Is it hard for you to get up early and get ready for classes? Some students at Winter Park High School just roll out of bed in their pajamas （睡衣） and go to class in their own bedrooms. Of course, their teachers and classmates do not see them because all their class work is on the computer.

The Florida high school, the state’s only on–line school, has 250 students who are taking classes at home by computer. “I’m a lot more comfortable at home,” says Luke Levesque, a 16-year-old boy who is taking a computer class on-line. He thinks the school’s computer lab is so noisy that he can’t study well. “Home is much better,” he says.

Students in this first on-line program take classes in Algebra （代数）, American government, chemistry, computer, economics, and Web-page design. They also have to go to a regular school to attend other classes.

When a student is ready to begin a class, he or she turns on the computer, reads the teacher’s instructions, and begins working on the lesson for the day. What happens if a student has a question for the teacher? Or the teacher wants to say something about the work a student is doing? The student and the teacher talk to each other every day through e-mail or he or she calls the teacher. For example, when Luke opened his daily e-mail from the teacher, it contained （包含） her instructions for the day’s computer lesson. When he finished, he e-mailed the work back to her for grading.

Is it easy for students to cheat on tests when they’re working at home? The teachers have already thought about this. They make students take their final exams in person in the classroom.

“You see most of the same things on-line that you see in a regular classroom,” says teacher Linda Hayes. “You get to know the students on-line.”

If this first on-line program goes well, in three years Florida high school students will be able to take all their classes by computer. When that happens, students will be able to get their high school diplomas （毕业证书） without having to set foot in a classroom.

3．What might happen in three years in Florida?

A．Students can take some of their classes on-line.

A new term has begun. Teachers are   1  about the fact that new students are not easy to deal with(对付). They like to bring telephones（手机） and MP3 players to school. What is   2  , some students even use telephones to do out-of-class matters in class, or sometimes just for fun. Some otherstudents listen to MP3 players when they are having a lesson that they are not interested in.
Are these new students really that  3 ? “Yes.” says Delaney Kirk, a professor at Drake University.   4  she says it’s not their fault(过错).   5 , the teachers should be blamed(责备). Mrs Kirk first began thinking about students’ manners six years ago. “I had my first class in which students were sleeping or talking to each other. It seemed that learning well had nothing to do with them.” she says. “At first, I got worried about this.” but then I said to myself, “You’re giving   6  , and you need to deal with this kind of situation (情况). These students need to know more about manners. It’s time to help them develop some good   7  . They shouldn’t waste time doing nothing when they are young. Sooner or later, they may regret(后悔) the time they have wasted.”
Mrs Kirk also   8  a list of suggestions(建议) to help teachers better manage (控制) their classes. The following are among her suggestions:
l     On the first day of class, tell students how they will benefit(受益) by taking the class and the importance   9  listening carefully in class.
l     Do not allow（允许） them to bring telephones or MP3 players to the class at all.
l     Tell them how to use telephones or MP3 players   10  .
