1. 画线部分about an hour表示上网花费的时长，对其提问要用疑问词组How much time；原句为一般现在时，主语从第一人称I变为第二人称you，需要借助助动词do构成疑问句，谓语动词保持原形spend。
2. 原句语义为“地震太小，因此人们无法感知到它们”，使用固定结构too...to...（太……而不能）改写，符合“地震太小了，以至于人们无法感觉到”的含义。
3. 合并两句时，用固定短语instead of（而不是）衔接，表达“用电子货币而不是现金”的含义。
4. 画线部分search for information是动作内容，对动作内容提问要用疑问词What；原句是一般现在时，主语Jack是第三人称单数，需要借助助动词does构成疑问句，谓语动词用原形use，最后一空填do指代原画线部分的动作。
5. 原句是一般过去时，谓语动词came是实义动词come的过去式，改为一般疑问句需要借助助动词Did，后面谓语动词还原为原形come，固定搭配come into being保持原形；肯定回答用it指代the first electronic computer，后接助动词did。
【答案】：
1. How much time do; spend
2. too small
3. instead of
4. What does; use; do
5. Did; come into being; it did
