状语是英文句子里面的基础款，人人都知道，那么今天联邦雅思带大家重温的知识点是 - 伴随状语。
a. For example, painting, music and movies accessible in the media have a small number of genres, imposing restraints on one's knowledge of artworks of different cultural backgrounds.
[imposing restraints on one’s knowledge，就是现在分词当伴随状语，和主句的主语有主动关系，同时也和主句的谓语have a small number of genres是同时发生或者伴随着发生的。]
b. Unfortunately, many Asian people now imitate American people, causing the alteration of their perceptions of family.
[causing the alteration of their perceptions of family，是伴随着“亚洲人模仿美国人“发生的]
c. Having no atmosphere, the Moon is a permanent base for people to observe the universe easily and provide them with sufficient evidence they require for decision making on a great many significant issues.
d. According to the pie chart, chicken, which is 40%, is the most popular among the total meat sold, then next is pork with 20%, followed by beef, making up 18%; and finally come lamb, fish and other at 15%, 5% and 2% respectively.
[这个句子是我们小作文里面很常用到的，这里的followed by beef就是过去分词当伴随状语，表示被动]
e. They will send you the book for $2.50, postage included.
For example, with the humanitarian relief obtained worldwide on an annual basis, victims of natural disasters (such as tsunami, draught, flood) throughout the world can recover rapidly and rebuild their homeland.
[with the humanitarian relief obtained worldwide on an annual basis是伴随状语]
