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.
A. running; that B. run; who C. running; who D. run; that
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
