    經(jīng)典舉例：

    1、Many people insist that... 很多人(堅持)認(rèn)為……

　　這句話乍看沒亮點，但將眾人皆知的"think"換為"insist"有沒有覺得高大上了許多?

　　2、With the development of science and technology, more and more people believe that... 隨著科技的發(fā)展,越來越多的人認(rèn)為……

　　這個可是小編當(dāng)年的"殺手锏"啊，雖談不上洋氣，但正確率百分百啊，還超好記!

　　3、A lot of people seem to think that... 很多人似乎認(rèn)為……

　　"think"終于閃亮登場，但"seem to"為整個句子增添了點婉轉(zhuǎn)之感，這種客觀的方式貌似較受老外(尤其腐國人)喜愛。
