帮忙讲两个小小的英语选择题哈···
1.—— a dog with a wolf,and you will find it difficult to tell them apart.
A.Compared B.Compare C.Comparing D.To compare
2.The newly-built library,the walls of——are painted light green,is really a peaceful place for us.
A.that B.it C.what D.which
KEY:1.B 2.D
晓不得为什么选这个···

答案

第一题,注意到and了吗?意思就是,这是两个并列句,应该选一个能使前面构成完整句子的词,所以选B,形成一个祈使句.
第二题,The newly-built library是主语,the walls of——are painted light green是主语的修饰部分,也就是定语.那么这里就相当于一个定语从句了,所以选which.不选that,因为是修饰主语的.不选what,因为是定语从句.
