参考答案：

1.C limit：限制，局限。电视台的位置是受到局限的。prohibit：vt.禁止。bound：vi.跳跃，跳动。shift：vt.转移，移动。

2.A range射程，有效距离，量程。如：We waited until the enemy was within range，我们等敌人进入了射程。本文指中转站能发射到的距离范围之内。

3.B根据上下文的逻辑关系，需要一个转折关系的连词。本句含义为：为了发射的范围更广一些，虽然电视中转站经常设在高山上，可是却远不如设在山顶上发射的范围广。

4.A cover：vt.覆盖。spread：vt.传播；help：vt.帮助；pass：vt.通过。此处指中转站覆盖的地区。

5.C通常说on a clear day。强调具体的时间时用介词on。如：on Friday，on the eveningwhen l was busy。

6.D根据上下文的逻辑关系，此处要用表示条件的句子，加上与前面的句子是并列关系，所以选D。

7.B revolve around：绕转，公转（主要指星球，球体），此处指卫星绕着地球转动。spin：vi.旋转（以……为轴）。the top was spinning merrily.陀螺在轻快地旋转着。jump：vi.跳跃。circle：v.使转圈，在……上方盘旋。

8.B visible能看得见的，是形容词。其余的都是动词，放在这里是被动语态，不符合语法。

9.C permanently：adv.永久地，永恒地。al-ways：adv.总是。temporarily：adv.临时地，暂时地；periodically：adv.周期性地，定期地。卫星应该被永久固定在一处进行节目的转播。

10.A根据文意，此处要表达的意思是“这使得世界范围内发行的报纸能够同时向全世界发送新闻。”指示代词this和that可指代前文的句子或句子中的一部分。This指代距离较近的内容。因此A项最合适。

11.B edition：版本；这里指报纸的出版。popuIation：n.人口；articles：n.文章；reports：n.报道。此三项均不符合题意。

12.C someday：表示将来的某一天。the other day：前一天。on day：有一天。future：n。将来。未来。一般用in the future。因此C项正确。

13.B press a button：按动电扭，最符合题意。touch：触摸，接触，主要强调触觉，一般不和button搭配。suppress：镇压。thumb：用拇指翻动。

14.C on the television screen在电视屏幕上。

15.B 当不定式修饰want，have等动词的宾语、而整个句子的主语是不定式的逻辑主语时，不定式用主动形式表示被修饰宾语的被动含义：We have little homework to do.（我们没有多少作业可做。即：没有多少作业可以被做。）（实际上是we do homework，所以用主动语态）；She felt tired because she has three babies to look after.（她要照看三个孩子，所以很累。）（实际上是she looks after the habies，所以用主动语态。）

16.C 前面有he could…，后面又有he could…明显是两个并列句，所以选and。

17.C为了避免重复，可用that，those代替前面提到过的名词。但this，these没有这种用法。

18.B methods of past：过去的方法。

19.A press agency：新闻机构。

20.D send message：发送信息。
