experience(d)

1.说“有某种经验”通常用完成时态。例如：I have had much experience of country life.

2.experience和动名词的中间用of或in都可以，如experience of teaching和experience in teaching。long experience, many years' experience等后面通常接of, many years of experience等后面通常接in，have had experience后面通常接of，gain experience后面通常接in。例如：

• His long experience of teaching foreign languages is a great asset.
• Many years' experience of teaching foreign languages qualifies him for this post.
• Many years of experience in teaching foreign languages qualifies him for this post.
• He has had much experience of teaching foreign languages.
• He hopes to gain experience in foreign languages.

3.a very experienced teacher里用very比用much或very much普通。
