    His presentation will show you ____ can be used in other contexts.

    A. that you have observed
    B. that how you have observed
    C. how that you have observed
    D. how what you have observed

    答案：D
    解析：
    考查从句。show sb sth结构，这里sth是how引导的宾语从句，宾语从句中缺主语，what引导的主语从句，翻译为“所??的”what作observe的宾语。句意为“他的发言将向你展示，你所观察到的如何被用于其他语境”。所以正确答案为D。

    解析：
    本题考查动词时态。题目意为“你多久检查一次牙齿？”应用一般现在时，have sth done表示让别人给自己做某事，选项A为正在进行时，选项C为现在完成时，选项D不是疑问句，错误。故选B。

  • 第15题：

    Given that you have a class B IP address network range, which of the subnet masks below will allow for 100 subnets with 500 usable host addresses per subnet?

    A．255.255.0.0

    B．255.255.224.0

    C．255.255.254.0

    D．255.255.255.0

    E．255.255.255.224


    正确答案：C
    解析：Explanation:
    Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of networks.

    Again using the 2n-2 formula, we have 2n-2 = 126 networks that are available.

    Incorrect Answers:
    A. This will provide for only 1 network with 216-2 = 65534 hosts
    B. This will provide for 6 networks with 8190 host addresses.
    D. This will provide 254 networks and 254 hosts.
    E. This will provide 2046 different networks, but each network will have only 30 hosts.
