题型:阅读理解

阅读理解。

     Learning new words is learning new ideas: High school students can take control of their learning by

always looking up new words and finding out what they mean. They should keep a dictionary and a

thesaurus (分类词典) close at hand.

     Make clear lists: Students should make a list of everything that they need to get done. They should

check off assignments (作业) once completed. They should include clear due dates.

     Make a commitment: Active learners will resolve to keep up-to-date from the start. They will avoid

procrastinating. They will complete most of their work as early as possible.

     Independent work is best: Students will do all assignments independently-they will never copy! Students

who copy are passive learners. Passive learners do not give their mind a chance to think on its own.

     Organization is key: Students should keep an excellent folder and notebook. All problems should be clearly

stated and solutions given. All tests and quizzes should be corrected and used as study guides for exams and

finals.

     All actions without solutions are dead: Active learners will always show their work needed to solve a

problem. Active learners will never turn in a list of answers without giving an explanation or a solution.

     Advanced reading: Students should do any required reading for the topic before class. They should write

an outline of the section or chapter. They should actively take notes as they read to help them remember.
