在通读全文时,一定要注意文章中一些表示转折和承接的连词或副词。如and,but,however,besides,first,second,then,later,finally等。其次,还应该注意上下文之间的联系。例如当在文中出现并列连词and,or,rather than,not only…… but also, not……but, either……or, neither……nor……等时,应该注意它们所暗示的前后句中的两个平行结构。再如在That day he went shopping rather than (stay) at him.中,既然rather than前面是过去式went后面肯定就用stay的过去式stayed,这就是“功能语法同现”理论的体现。
