问几道英语口语交际题目？

Question

A: I'm going to do some shopping!
B: Where are you going?
B: Xidan street.
A: OK._____________________,My bike is over there under the tree.
B: Thank you.
A: _______________________.Please give it back soon .
B: All right

这两个空。答案给的是“Here's the key”和“You are welcome"
但为什么不可以填“I would like to lend it to you”和“When you come soon”

还有我想问下各位这样的英语考题的答案唯一吗？谢谢大家

Answer 1

有时候答案并不唯一，I'd like to lend it to you虽然语法上没毛病；但人家既然是把钥匙给你，而且告诉你自己的自行车是在树下已经明确表明要把自行车借给你了，再填I'd like to lend it to you就重复了，而且仍然还得说把钥匙给你
Thank you,对应的下文当然是You are welcome 更合理

Answer 2

哈哈太生硬了你的回答
兄弟都向你借自行车了你还说 兄弟我现在借给你哈。太见外了。

答案当然不固定了。
下面一空可以填 My pleasure之类的回谢用语。

Answer 4

前一个答案比较符合语境，后面的回答就比较生硬。口语问题还是应该要符合语境，答案当然不是唯一的。

Answer 5

后面一句不止一个答案，You can use"Not at all".
