(1) 相同点 都可表示建议做某事， advise与suggest后面都可接名词/动名词/ that从句（should加动词原形，should可以省略）。例如：他建议（我们）再等一会儿。He advised/ suggested waiting a bit longer.He advised/ suggested (our) waiting a bit longer.He advised/ suggested that we (should) wait a bit longer.上面的第三句可转化为：It was suggested that we (should) wait a bit longer.What he suggested was that we (should) wait a bit longer.His suggestion was that we (should) wait a bit longer.(2)不同点①advise后可以直接跟人称代词作宾语，如：advise sb. to do sth.; advise sb. against (doing) sth.; advise sb. on/ about sth.; 而suggest后一般用suggest to sb that …形式。如：他建议我们改天再来。[正]He advised us to come another day.[误]He suggested us to come another day.[误]He suggested us that we come another day.②suggest还有“暗示、表明、指出（一个事实）”的意思。此时从句中用陈述语气，不用虚拟语气。如：Her expression suggested pleasure. 她面露喜色。His silence could only suggest disapproval. 他的沉默只能暗示反对。句中需要一个暗示的意思，所以选B不懂可追问，希望可以帮到你
1. What he says suggests that he doesn't want to go with you.(suggest“表明、表示")2.This sign stands for "turning left".(stand for代表)3.This map represents the area of the United State.(represent代表)4. It indicates that you haven't turned on the machine.(indicate表明、暗示)
选 C首先advise与suggest比较：(1) 相同点 都可表示建议做某事， advise与suggest后面都可接名词/动名词/ that从句（should加动词原形，should可以省略）。(2)不同点①advise后可以直接跟人称代词作宾语，如：advise sb. to do sth.; advise sb. against (doing) sth.; advise sb. on/ about sth.; 而suggest后一般用suggest to sb that …形式。如：他建议我们改天再来。[正]He advised us to come another day.[误]He suggested us to come another day.[误]He suggested us that we come another day.②suggest还有“暗示、表明、指出（一个事实）”的意思。此时从句中用陈述语气，不用虚拟语气。如：Her expression suggested pleasure. 她面露喜色。His silence could only suggest disapproval. 他的沉默只能暗示反对。由上面的例子看出，这道题首先应该选advise这个动词，然后看整句话的时态，是一般现在时，所以用advises。
