谚语在大学英语四级作文很有必要：
1. 谚语可以提高文章的表现力。谚语由于经过时间和人们智慧的沉淀，常常蕴含着深刻的哲理和精神内涵。运用恰当的谚语能够使文章更具有感染力和表现力。
2. 谚语可以增加文章的文化色彩。谚语是中国文化和民间智慧的重要组成部分，使用谚语不仅可以体现作者的文化底蕴，同时也能够向外国读者展示中国文化魅力。
3. 谚语可以引申出文章的主题和内容。运用恰当的谚语，可以巧妙地衔接文章的主题和内容，使其更加连贯、一致，读者容易理解和接受。
但是需要注意的是，谚语的使用要适度和恰当。不需要在文章中过多、强行地使用谚语，会显得不自然和敷衍；同时也需要考虑目标读者是否能理解所使用的谚语。
