请帮我看看这道
Grover was the first president-------in the white house.
A.got married B.to get married C.has got married D.was married
选B
答
句子已经完整，缺少非谓语动词
4个选项中只有B是非谓语动词。
如果有类似getting married或having got married的选项还是选B，因为名词前有first修饰，就必须要用不定式to get married
答
the first to do sth. 是一个固定用法
答
.to get married 做后置定语，修饰 president
其他答案均不符合题意
be the first/second/third one to do sth 是第一（二，三。。。。）做某事的人（或物）
答
是个固定句型。第一个作某事的人。。sb is the first to do sth.
答
主语Grover, 谓语是系表结构 was the first president. 这已经是完整的主谓句子了,而 A,C和D都是谓语的结构,一个句子不能有两个谓语.
B 是一个to的不定式,可以做修饰用
答
这叫不定式做定语。其它都需要主语的
答
如果选其他选项的话不就形成了有2个谓语，一个句子只能有一个谓语
