同学好，
there is no basis for后可接名词或动名词，表示....是没有根据的
如：There is no basis for recommending DHA supplementation for patients with Alzheimer disease, the authors concluded. “推荐在患有阿尔采末氏病的患者上补充DHA的说法是站不住脚的。”研究者作出结论说。
There is no basis for his opinion that the earth is flat.  他认为地球是扁平的，这毫无依据。
it would be advisable后可接介词短语，to do不定式，that从句等形式，表示：....是明智的
如：It would be advisable for you to instruct a credit agency to investigate the matter.  贵方指示信用调查机构调查这件事是明智之举。
It would be advisable to adjust the mixing time by conducting specific tests. 宜调整时间进行具体的测试。
It would be advisable that all the lines out there should be consolidated and be put in his charge.  我认为，把那儿所有铁路统一起来，交他管理，倒是好办法。
祝学习愉快~
