1.The washing machine _____woks well.
A.I bought last Thursday         B.which was repaired last week
C.whose sides are all white    D.that is made in Shanghai
为什么选A，是不是它省略了that?

2.Joan is one of the best writers________.
D.that has been givenmedals
D 可以选吗？为什么？

3.The earth goes round the sun,_______even a child.
A.which  B.that   C.as  D.it
C项是正确的吗？请解释一下！
麻烦各位啦！

没人可以帮我解释吗？
伤自尊唉………………………………………………

1. A  Yes. that is ommited.
2. D is not right. should be "that have been given..." because you need Plural form after "one of ..."
3. I dont think the question is quite clear. is there anything missing?
since i cant type Chinese right now, i dont know whether i have made myself understood. hope it will help.

谢谢你！
第三题我只是想问可不可以选C
如果把C代入句子怎么翻译？

有没有人可以帮我解释完这道题目啊？
麻烦各位啦！
