    You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.What could be the cause of this problem?（）

    A. OSPF authentication errors between some of the routers

    You'd better make a mark__________ you have any questions while you are reading thepassage.

    A．at which
    B．in where
    C．in the place
    D．where

    答案：D
    解析：
    考查状语从句。句意为“当你读文章时，最好在有问题的地方做个标记”。从句中缺少表示地点的状语，所以用where引导地点状语从句。而当where引导定语从句时，要有先行词place，加上at可以改成“You’d better make a mark at the place where you have any questions”。
