A:That interests Mary really
B:Which really interests Mary.
C:What really interest Mary
D:What really interests Mary
答案:AI参考:正确选项是D:What really interests Mary。\n\n句子中使用了“What is to dance”这样的结构，需要使用疑问代词来引导一个疑问句。选项D中的“What really interests Mary”符合语法规则，表示“什么使玛丽感兴趣”，符合句意。选项A、B、C中的语法结构不正确，不符合疑问句的语法规则。因此，正确答案是D。'
2.I won't trust him. He says one thing to your face but does ___ behind your back.
A:the other
B:another
C:other
D:the others
答案:AI参考:正确答案是C:other。\n这句话的意思是“我不会相信他，他当面一套，背后一套”。other表示“其他的”，符合语境。the other表示两个中的另一个，another表示三者或三者以上的另一个，the others表示其他的人或物。因此，选项C是正确答案。'
3.___ is 200 kilometres from here to the natural park. We have to go there by car.
A:It
B:There
C:This
D:The place
答案:AI参考:正确选项是【D:The place】。\n\n根据题意，“从这里到自然公园距离200公里，我们必须开车去那里”，需要填入一个表示地点的名词，而选项中只有D选项“The place”符合要求，表示某个地方。所以答案为D。A选项“It”可以指代前面的“200 kilometres from here to the natural park”，但整个句子的主语应该是“we”，所以A不正确。B选项“There”是副词，不能作为名词使用。C选项“This”作为代词，无法作为地点名词使用。'
4.He was seriously ill when he was a boy, made him lose his sight.
A:how
B:who

D:that
答案:AI参考:正确选项是【D:that】。\n\n句子中使用了定语从句，修饰先行词He，表示“他小时候生了一场重病”，而选项D中的that可以作为定语从句的关系代词，引导定语从句并在从句中作主语，符合语境。因此，D是正确选项。A、B、C都不符合定语从句的结构和语境。'
5.Is there anything I can do for you?
A:that
B:which
C:how
D:who
答案:AI参考:正确答案是C：how。\n这是一个问句，“有什么我可以帮你做的吗？”的固定搭配是“what can I do for you?” 所以“anything”与“how”可以作为助动词，“how”用来提问方法，策略等。所以选择C选项。'

A:what is this used for
B:which this is used
C:what this is used for
D:that this is used for
答案:AI参考:正确选项是C:what this is used for\n\n这个问题询问的是这个事物被用来做什么，所以需要使用疑问词what，并在句子中加上is used for作为be used for的简单形式。因此选项C是正确的。选项A和D中的句子结构不完整，而选项B中的which是用来选择特定事物的，与问题不符。'
