can you help me translate the following sentences?
我们应该把语法结合到句子,文章中去学,灵活掌握.例如,例如我们都知道many 后要跟一个可数名词复数,但同学们有时会看到这样的句子：Many a student has seen this painting.（许多同学都见过这幅画）.这里many后加可数名词单数谓语动词用单数但表示复数意思；又如我们学过suggest后的从句通常用虚拟语气,但同学们也许见过这句话The look on his face suggested that he was scared.(他脸上的表情表明他吓坏了.) 物做suggest主语时有“表明、使人认为”的意思.
