Answer 1

1. The past several years have （因为是years 所以不可以用单数）witnessed a social phenomenon that an (因为后面的单词是原因开始，所以不应该用a）increasing number of people are concerning (用一般现在时更好些） about the importance (应该用名词，而不是形容词） of their lives（每个人的生命/生活，所以用复数）.

2. The several years have (同样的错误）witnessed a social phenomenon that an(同上）increasing number of foreigners fall in love with Chinese culture. 这句话基本没有问题。
