24. [d] means
解析：means是单复数同形的名词，表示“方法；方式；手段”。例如：

毫无疑问,收音机和电视是交流的重要工具。
the local army men helped the victims of the earthquake by every means at their command.
当地的军人用一切可能办法帮助地震灾民。 means还有“收入；财富”之意。例如a man of means有钱人。
means, instrument, agent, medium, vehicle这组词都可以表示“借以成就某事或达到某目的人或物”。
means 可以指人或物，其含义为“手段”或“工具”；这个词不仅用于具体的东西，也可以用于抽象的意念。如：means of production 生产资料，means of living 生活资料。

instrument 主要用于表示按别人的意志行事的人，在用于表示事物时，其含义由musical instrument (乐器)引伸而来，因此 instrument 在表示“工具”或“仪器”时的内涵是操作灵敏，一触即应。
but can we blame those who looked and failed to see what galileo saw, if we remember that to use a telescope at the limit of its powers calls for long experience and intimate familiarity with one's instrument?
然而， 如果我记起这样一个事实：使用一架倍数有限的望远镜需要长期的经验和对仪器的完全熟悉，我们难道能够责怪那些作过观察但没有看见迦利略所看见的东西的人吗？
he was made the instrument of that man’s crime.
他被迫成为那人犯罪的工具。
agent 的原义是“起作用的人”或“办事的人”，现在的常用含义是“代理人”，即区别于筹划人或行使意志者
many firms, for instance, have great difficulty in obtaining technical or scientific books from libraries because they are unwilling to have their names entered as having taken out such and such a book for fear the agents of other firms should be able to trace the kind of research they are likely to be undertaking.
例如，许多公司在向图书馆借技术或书籍时非常难办，因为这些公司不愿让自己的字号作为借出这种那种图书者登记入册，生怕其他公司的情报人员可能探索出他们有可能在进行的科研种类。
medium 的含义是“介质”，没有这种“介质”便达不到一定的目的
vehicle 所表示的“媒介物”主要指借以传递意欲流露的思想、感情等手段。这个词的这一含义与“运输工具”这一含义有关。因为vehicle也是汽车等运输工具的总称。
art may be used as a vehicle for propaganda.
艺术可以用作为宣传的媒介。
language is a vehicle of human thought.
语言是人类表达思想的媒介。
25. [b] that

27. [b] wander
解析：wander常与in, off连用，意为“漫游； 漫步；漂泊”。例如：

狗也有较多的自由，因为允许它们在围栏外边随便走动。

他们把一整个上午的时间都花在树林中游荡上了。
28. [a] deciding
解析：deciding在此处引导的现在分词短语，修饰名词（主句中的宾语）users。本题容易误选成[d]to decide。该选项之所以错误，是因为to decide给人感觉是目的状语，但是原文中没有明确的目的的含义。（互联网用户在网上四处游逛，同时决定浏览哪些内容，“决定”在此间并非“目的”，而是修饰浏览的“状态”。）
29. [d] transfer
解析：transfer:（常与to连用）迁移；调任；转移。一般包含空间上的转移之意。例如：

老板把他调到了另一个办公室。
其他选项：

a newspaper reader can select what he is interested in and skip what he thinks is boring or irrelevant.
报纸读者可以选择自己感兴趣的新闻,略过自己认为是枯燥的或无关的消息。
近似含义还有，“不参加某项活动；缺席”。例如：

其他选项：
[a] flip 1）轻弹；弹投，弹抛；翻。例如：
to flip an egg over in the pan
把锅里的蛋翻过来
2）（俚语） 发疯。例如：

我哥哥发现他的新车上有个被撞瘪的地方，就发疯了。
i knew you’d flip when you saw my new house and furniture.
我知道要是你看见了我的新房子和家具,你准会激动。
[b] slip 1) 滑落；跌跤

她滑倒在发亮的地板上了。
2) （常与in, out, away连用）溜走；悄悄过去

[a] success 名词，成功
[c] assess 动词，评估
[d] possess 动词，占有，拥有
32. [d] to
解析：point to指向。
容易误选成at。该选项之所以不是最佳，是因为point at一般有“指向某一特定点”之意。
33. [b] of
解析：places of interest on the web网络上有意思的去处
34. [d] appear
解析：主语为复数名词addresses of webpages，同时该句描述的为一般情况，应该用动词appear的一般现在时，即原形。
35. [c] turn
解析：in one’s turn，是in turn (依次，轮流)的另一种用法。
36. [d] forms
解析：form此处表示“形式”。[a] mode强调“模式”，不是最佳选项。forum：论坛，讨论会，会议场所。
37. [a] beyond
解析: go beyond: 超出。原句为most webpages offer interactive opportunities which go beyond merely allowing visitors freedom as to when and how they visit a page and where they might choose to go next.意为：大多数网页(为网虫)提供互动的机会，让那些访问的人在自主决定什么时候，用什么方式来访问网页，以及下一步点击哪里之外，还能有更多选择。
38. [b] out
解析：fill…out表示填写。fill…up意为“填满”。
39. [c] installing
解析：介词by后面应该用动词install的现在分词形式。
40. [d]limit
解析：limit, restrict, confine这三个动词的一般含义为“限制”或“局限”。
limit 指时、空、程度、量等方面的“限定”，其内涵是如果超出了这种限度就会受罚或遭到令人不快的后果；此外，这个词也常用来表示“局限”

we must limit our expense to what we can afford.

restrict 区别于limit 的地方在于，restrict“限制”的是范围，而limit 侧重于表示“限制”到某个点。
in democratic countries any efforts to restrict the freedom of the press are rightly condemned.
在民主的国家里，限制新闻自由的任何努力都要受到公正的遣责。
the trees restrict our view.
这些树局限了我们的视野。
confine 具有 limit 和 restrict 两者的含义，但 confine 的内涵是“约束”或“束缚”
