1.A majority of the international journalists surveyed view nuclear power stations as unsafe at present but that they will, or could, be made sufficiently safe in the future.
这道题我觉得就是D中补出来的think隐含主语是记者,所以保证了后面的they指代 nuclear power stations ;
如果没有think做暗示,那么可以认为they能形成指代不确定的错误;还有就是大全的解释中有句对D的解释说:Choice D is best: that, although not essential, is preferable here;;;这里怎么理解对that的论述啊;宾语从句一定要that没有错啊,怎么说that 不essential呢?????
