答案与题解：
1. C “空1”应该填入与low-level radiation 有关的内容，例如 low-level radiation 究竟有害还是无害。所以，C是合适的选项。此外，直接阴郁也佐证了选择的合理性。
2. B “空2”前面一句介绍了澳大利亚拥有手机的现状。选项B的内容是对到2000年年底之前手机发展前景的预测，内容连贯，是正确答案。
3. E 这一段的第一句说的是，许多微波发射塔建在人口稠密的居民区。选项E的内容涉及微波发射塔的地点选择只考虑到地理位置，而不顾及公众的需求。选项E扩展了第一句表达的信息。此外，选项E中出现 tower 这个词，与第一句的 tower 相呼应，也佐证了选择的合理性。
4． A “空4”前面一句说的是Robert Bell建议政府应该禁止在学校操场、儿童日托中心、医院、运动场所以及儿童占比例较高的居住场所方圆500米范围内建发射塔。选项A说明要这样做的原因，因而是答案。
