Answer 1

1.If Ken comes late,( )is usual for another time,we'll not recieve him anymore.
A.which B.thar C.it D.as
答案是D。在非限制性定语从句中，as可以表示指代前面整句。这里所缺的关系代词，恰恰需要能够指代整句的as。
2.Rose knew that her son dreamed that he could succeed ( ) she had failed.
A.what B.that C.which D.where
答案是D。地点状语从句，用连接词where。
3.Mrs Black took the police back to( )place( )she witnessed the robbery.
A.the same;that B.the same ;as C.the same;where D.as the same;as
答案是C。”布莱克女士带那位警察回到了她目击抢劫的地方。“place作先行词，关系词在从句中充当地点状语，故用关系代词where。
4.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
答案是A。running from east to west作伴随状语；those are called avenues说明those是物，故用能作主语或宾语的that作关系代词。

Answer 2

1. as is usual, 像往常一样，固定搭配，as...正如...
2. where 引导的地点状语从句，Rose明白她的儿子梦想可以在她失败的地方取得成功。
3. take...back to，to是介词，可以加地点place，不用再加as；同样，where引导地点状语从句
4. 进行时态running表示伴随，它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在，一般都是逗号隔开；that指代那些街道，who用来指人的本回答被提问者采纳

Answer 3

2.fail 可做及物动词 （查了字典)
3.the same place as 中as 可作状语（查了书 ）
