1)____hot summer days I go swimming and I do so ____warm winter days,too
A.In,on B,On,on c,In,in D,On,in
PS,我选B，但答案是A

答案是正确的。hot summer days是段时间，实际上就是hot summer，所以是in,而比较冬天比较温暖的日子，就是真正的day,day前面有形容词就要用on，常识问题，就不用解释了吧。

2）____(lose)time can not be found again.
ps,我填“lost",答案是“losing"
这道题就没什么道理，如果是要说丢了时间就找不回来了，两种其实都是可以的，而且2楼说的加the的说法很有道理，the losttime。。。会更通顺。

3)___two model planes,I prefer the smaller
A,Of the B,Between the
ps,我选B，答案是A
这个也应该选A， 两者中更喜欢哪一个，同2楼解释

4)There was on one about,and there was no garage open ____he could turn for help.
A,which B,with which C,to which D,that
ps,我选C，答案是D
这个应该选that,因为这个先行词指代的既有人，又有车库，回去翻翻定语丛句的语法书就知道了，先行词指代两者都有而且还有
no，关于哪些地方只能用that不能用which的，任何高中语法书都有。好好看看定语丛句，重头戏。
