1.【答案】D。解析：考查连词。从空白处看，but后一般不加逗号，排除A;though“尽管”语义逻辑不符，另外though作连词时后也不加逗号，排除B;or“否则;或者”语义逻辑不符;however“但是”作副词时后面常用逗号，又因however意“然而”，“但是”，填入空白处后，前后两句意思连贯，故D为正确选项。

2.【答案】B。解析：考查名词的可数与不可数。space, room意为“空间”时为不可数名词。句中有there were，需要和可数名词搭配，根据关键信息on the plane可知选择seats最合适。故选B。

3.【答案】B。解析：句意为当问小 John他的名字的时候，John没有回答。When引导了时间状语从句，做整个句子的状语;前半句完整情况应该是“when little John was asked what his name was”，做状语从句省略谓语动词。因此答案选B.

4.【答案】A。解析：考查形近词辨析。句意：现代生活中保护环境经常和科技的发展相冲突。四选项中conserve与preserve都有“保护”之意。conserve强调对有价值的东西珍惜，合理使用，常用于保护资源和野生动，或指节约使用资源。preserve主要指为防止损害、变质等而保存，使不受破坏，能长久保存下去。由此可知conserve更符合本题语境。

5.【答案】A。解析：考查名词辨析。句意：警方号召公众共同合作追踪失踪男孩。cooperation合作;combination结合;possibility可能性;capacity能力。
