1.Is this farm ________ they visited the day before yesterday?
2.Is this the farm ________ they visited the day before yesterday?
A.which B.the one C.where D.what
简析：第1题中主句缺少表语,只有B项才能保持主句的完整性.故选B.第2 题的主句本身已完整,应填关系代词作定语从句中及物动词visit 的宾语.所以,正确答案是A.
3.改错：Do you remember the book that I lent it to you last week?
简析：.该题中的that 指代先行词book,在定语从句中充当了动词 lend 的逻辑宾语,故 it 应该删除.
5.Nearly all the streets are in straight lines,________ from east to west.Those ________ run from north to south are called avenues.

6.There is no such place ________ you dream of in all this world.

8.The artist will not paint people or animals but he will paint anything ________ .
A.that the little girl asks him B.the little girl asks him to
C.for the little girl to ask him D.what the little girl asks him
5.A.主语与run(延伸)是主动关系,所以用现在分词.Those指街道,所以不用who而用that来引导
6.当定语从句的先行词前有such,so,as等词语时,由as引导,并且as在定语从句中作主语或宾语,as在此题中作dream of的宾语.注意：在表示“如此…以致…”的such /so…that…结构中,that不作任何句子成份.
7.A.因为先行词是Beijing而不是this autumn所以用where引导定语从句.
8.B.答案B是省略了关系代词that的定语从句,另外,to后还省略了动词原形paint
