31:The use of modal verbs in English is always followed by the base form of the verb.
正确( ) 错误( )
答案:错误
解析:虽然情态动词通常与动词原形一起使用,但并非所有情况都是如此。例如,在动词是be、have或do时,它们分别用am/is/are、has/have和do/does来代替动词原形。因此,情态动词后面不一定总是跟动词原形。

答案:错误
解析:情态动词“should”不仅用于表达义务,还可以表示建议、推测或期望。例如,“You should study more”表示建议,“He should be back soon”表示推测。
33:The modal verb 'must' can only be used in the present tense.
正确( ) 错误( )
