ndverbinasentenceagreeinnumber.Ifthesubjectissingular,theverbshouldbeinthethird-personsingularform.Ifthesubjectisplural,theverbshouldbeinthepluralform.Forexample,"Shewriteswell"(singularsubjectandverb)and"Theywritewell"(pluralsubjectandverb).解析：本题考查主谓一致的原则。英语中的主谓一致要求句中的主语和动词在数量上保持一致。如果主语是单数，动词应该是第三人称单数形式。如果主语是复数，动词应该是复数形式。例如，"Shewriteswell"（单数主语和动词）和"Theywritewell"（复数主语和动词）。6.参考答案：Thepresentperfecttenseisusedtodescribeactionsorsituationsthatbeganinthepastandcontinuetothepresent,oractionsthathavebeencompletedrecentlybuthaverelevancetothepresent.Forexample,"Ihavelivedhereforfiveyears"(actioncontinuestothepresent)and"Ihavefinishedmyhomework"(actioncompletedrecentlywithrelevancetothepresent).解析：本题考查现在完成时的用途。现在完成时用于描述在过去开始并在现在继续的动作，或者最近完成但对现在有关系的动作。例如，"Ihavelivedhereforfiveyears"（动作延续到现在）和"Ihavefinishedmyhomework"（最近完成但对现在有关系的动作）。7.参考答案：Countablenounsarenounsthatcanbecountedandhavebothsingularandpluralforms.Uncountablenounsarenounsthatcannotbecountedanddonothavepluralforms.Forexample,"book"(countable)and"information"(uncountable).Countablenounscanbeusedwithnumbersanda,an,andthe,
