     You probably think you will never be a top student. In fact, you can become a better student if you want
to. You maybe say, 1"It takes me lots of time to study, but I don't still make progess." But if you can use your
time well, you may improve your study without much work. There are a few ways here to help you with your
study. 
     2 Plan your time carefully. You should make a list of things that you have to do during a week. First, you
should write down the time for eating, sleeping, dressing, etc. Then you should use the time that you can study.
3 Of course, studying shouldn't take all of your time. Don't forget to leave enough time for hobbies yourself.
     Find a good place to study. Keep this place, which may be a desk or just a corner of your room. No games,
radio, or television! When you sit down to work, think only about the subject!
     Make good use of your time in class. 4 Listen to what the teacher says carefully. Careful listening in class
means less work later. You also need to take notes in class, because it can make it easier for you to learn well.
     5 Can you give any other ways to study?

     Is it hard for you to get up early and get ready for classes? Some students at Winter Park High School just
quickly get up 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 computers.
     "I'm a lot more comfortable at home," said Luke Levesque, a 16-year-old who is taking a computer class
on line. He thinks (A) 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 math, American government, chemistry, computer, and Web-page design. They also have to go to regular (正规的) school to attend other classes.
     When a student is ready to begin in class, he or she (B) _______ 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 students is doing? The student and the
teacher talk to each other every day through e-mail or by telephone.
      Is it easy for students to cheat on tests (考试作弊) when they're working at home? (C) 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.
     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 (D) 走进教室.
