【结构分析】
时间状语：Nowadays（现在）
主语：an increasing number of students 越来来越多的学生
系动词：seem 似乎是
表语：to attach less importance to spelling in English learning.不太重视英语学习中的拼写.
【注释】
像 seem（似乎是）、appear（看起来是）、prove（原来是）、turn out（结果是）等动词,都可以用作系动词,后面常常跟不定式作表语,表述主语所呈现出来的行为状态.另如：
I can't seem to get the story straight.我好象不能理解这个故事.
They appear to have misunderstood me.他们似乎误解了我.
He proved (to be) a doctor.他原来是个医生.
The resultwill definitely turn out to be just the opposite of their wish.其结果必然不会像他们所一厢情愿的那样,而只能适得其反.
短语 attach importance to sth.直译是“把重要性与某事联系起来”,其实就是“重视某事”.另如The old man didn't seem to attach any importance to the question (这老人似乎一点也不重视这个问题).
