  • 第3题：

    根据下面资料，回答
    By the time I finished high school, my interest in animals had grown, and I enrolled at a university to study biology. I learned soon enough that studying animals at this level was not in the animals′ best 31 . I remember one midterm exam in 32 each student was handed a large, freshly-killed frog and instructed to dissect (解剖) and mark a set of body parts. I looked at the 33 frog in front of me and was saddened that her life was 34 away for such a slight reason.
    A year later, in the same lab where I dissected the flog, I performed a small act of animal operation. We were 35 on fruit flies, and it was time to record the distribution of characteristics in their next generation. Flies were kept in small plastic bottles. Counting the number of flies with white or red eyes required first exposing them to ether (乙醚) 36 they could not move. The flies were then spread onto a piece of white paper 37 and counted. When the data collection was complete, the flies had no further use, and our instructions were to put them into a small glass dish of oil at the center of each desk, which was to be their final resting 38 .
    Once my little pile of flies had been counted, I pushed them off the edge of the paper. As we recorded our data, I kept one eye 39 them. Within minutes the pile was humming (嗡嗡叫) as tiny legs and wings beat their way out of the ether fog. I was extremely excited as they took flight. That was my first step in refusing to conduct scientific research that treated nonhuman life in a (n) 40 way.

  • 第4题：

    阅读以下说明，回答问题1～4，将答案填入对应的解答栏内。

    某公司的域名为xyz.edu.cn，所使用的网络地址为222.78.68.0/24，共有两台服务器，一台IP地址是222.78.68.10，名字是server1，它用作域名服务器、电子邮件服务器，另一台IP地址是222.78.68.11，名字是server2，它用作Web服务器。

    下面是服务器server1中的三个文件。

    /etc/named.conf文件的内容：

    options {

    directory"/var/named";

    };

    zone"．"IN {

    type (1) ;

    file"named.ca";

    };

    zone"0.0.127.in-addr.arpa"IN{

    type master;

    file"named.local";

    allow-update{none;};

    };

    zone"xyz.edu.cn"IN{

    type master;

    file"named.hosts";

    allow-update{none;};

    };

    zone"(2)"IN{

    type master;

    file"named.rev";

    allow-update{none;};

    };

    /var/named/named.hosts文件的内容：

    $TTL 86400

    @ IN SOA server1.xyz.edu.cn. root.xyz.edu.cn.(

    2001110600;serial

    28800;refresh

    14400;retry

    3600000;expire

    86400;minimum

    )

    IN NS server1.xyz.edu.cn.

    IN MS 10 server1.xyz.edu.cn.

    localhost.IN A 127.0.0.1

    server1 IN A 222.78.68.10

    server2 IN A 222.78.68.11

    WWW IN (3)

    /var/named/named.rev文件的内容：

    $TTL 86400

    @ IN SOA server1.xyz.edu.cn.root.xyz.edu.cn．(

    2001110600;serial

    28800;refresh

    14400;retry

    3600000;expire

    86400;minimum

    )

    IN NS xyz．edu．cn．

    10 IN (4)

    11 IN PTR server2．xyz．edu．cn．


    正确答案：(1)hint (2)68.78.222.in-addr.arpa (3)CNAME server2.xyz.edu.cn或者CNAME server2 (4)PTR serverl.xyz.edu.cn
    (1)hint (2)68.78.222.in-addr.arpa (3)CNAME server2.xyz.edu.cn或者CNAME server2 (4)PTR serverl.xyz.edu.cn 解析：不管是主域名服务器、辅助域名服务器还是缓存域名服务器，在根域名区声明时，类型type型必须为hint，即为一个区的高速缓冲文件，因此空(1)处应当填写“hint”。空(2)处所在位置是反向域名解析区声明，应当填写反向域名。反向域名由两部分组成，域名前半段是其网络ID反向书写，而区域后半段必须是“in-addr.arpa”。因此(2)处应当填写“68.78.222.in-addr.arpa”。空(3)处应当是定义一条别名记录。根据说明，该单位的www服务在server2上，即“www.xyz.edu.cn”和“server2.xyz.edu.cn”表示同一台主机，因此(3)处应当填写“IN CNAME server2.xyz.edu.cn.”，也可以只填写“CNAME server2”(注：若要填写“A 222.78.68.11”也可实现解析，但违背出题的初衷了)。空(4)处应当填写一条反向指针(PTR)资源记录，用来记录在反向搜索区域内的IP地址及主机，用户可通过该类型资源记录把IP地址映射成主机域名，此处应当填写“PTR serverl.xyz.edu.cn”。
