小题1:______

Most of us can find 15 minutes or half an hour each day for some specific regular activity. For example, one famous surgeon always made it a rule to spend at least 15 minutes on general reading before he went to sleep each day. Whether he went to bed at 10 p.m. or 2:30 a.m. made no difference.

小题2:______

Nearly all ‘speed reading’ courses have a ‘pacing’ element---some timing device which lets the students know how many words a minutes he is reading. You can do this simply by looking at your watch every 5 or 10 minutes and noting down the page number you have reached.

小题3:______

Obviously there is little point in increasing your reading speed if you do not understand what you are reading. If you find you have lost the thread of the story, or you can’t remember clearly the details of what was said, re-read the section or chapter.

小题4:______

Take four or five pages of an interesting book you happen to be reading at the time. Read them as fast as you possibly can. Do not bother about whether you understand or not. After a ‘lightning speed’ of reading, you will usually find that your ‘normal’ speed has increased.

小题5:______

Most paragraphs in an article have a ‘topic sentence’ which expresses the central ideas. The opening paragraph often suggests the general direction and content of the piece, while paragraphs that follow expand or support the first. The closing paragraph often summarizes the very essence(实质) of what has been said.
