5. Industrial communities should be close enough to crowded centers _____________________________ (但也要足够远以降低潜在的危机).
答案：
1. It is easy to see that the people of different cultures have always copied each other (总是相互借鉴的)
(本题考查完成时态和相互代词。从“总是”可以看出，这里应用现在完成时，相互代词只有each other和one another两个词组，表示句中动词所叙述的动作或感觉在涉及的各个对象之间是相互存在的)
2. Tom kept quiet about the accident so as not to lose his job (为了不丢掉他的工作)
(本题考查不定式的特殊句型so as to，这个句型用来表示目的，它的否定句是so as not to do)
3. The government that refuses to meet the needs of its people must bear the consequence (必定自食其果)
(本题考查固定搭配，consequence指某种特定条件或原因考试365产生的后果，通常指不好的结果，bear the consequence“承担后果”是固定搭配)
4. Seen from space (从太空看)，the earth looks like a huge water covered globe.
(本题考查被动语态，过去分词seen表示被动意义。过去分词短语作状语时，其逻辑主语是句子的主语。地球是被看的对象，而不是这个动作的发出者，所以这里用被动语态)
5.Industrial communities should be close enough to crowded centers but distant enough to reduce potential dangers (但也要足够远以降低潜在的危机)
(本题考查转折关系，本句中使用but前后对照，后面的词应该和close相对，distant符合题意)
