Question

问个英语题、、比较晕。谢啦··希望能解释一下为什么，万分感谢呐O(∩_∩)O~

1.Meeting my uncle after all these years was an unforgettable moment,___I will always treasure. A that B.one C.it D.What
2.Meeting my uncle after so many years is an unforgettable experience,___I will always treasure. A.what B.that C.which D./
3.Meeting my uncle after so many years is an unforgettable experience___I will always treasure. A.one B.that C.what D./

Answer 1

1.Meeting my uncle after all these years was an unforgettable moment,_B__I will always treasure.
A that B.one C.it D.What
这里后边的是一个同位语从句，引导词用one
2.Meeting my uncle after so many years is an unforgettable experience,_C__I will always treasure.
A.what B.that C.which D./
有逗号分隔的从句，这是一个非限定性定语从句，用which引导
3.Meeting my uncle after so many years is an unforgettable experience__B_I will always treasure.
A.one B.that C.what D./
与第二题相对应，没有逗号时是一个限定性定语从句，引导词可以使which和that。
总结：对于1,2题，从句可以做不同的成分，主要是看选项。
