if a player chooses either two develop or two settle actions,then two complete,sequential phases of that type occur(with this player receiving a bonus in each of them).
如果有个玩家选择了2张开发或者2张扩展卡，那么就要执行两次相应动作。（比如玩家A选择了2张开发，那么在这回合他执行两次开发，可以用2次相应的特权，就是每次开发都减一张牌）。
If his opponent also chose one of these same actions,then his opponent receives a bonus only for the first of these two phases.
如果此时，对手也选择了其中一张牌，那么对手只获得一次bonus。比如玩家A选择了两张开发，玩家B则选择了一张开发，一张生产，那么对玩家B来说只能开发一次，减一张牌。
Powers placed in the first such phase can be used in the second one.
举例：玩家A如果选择2张扩展，那第一张扩展放下去的星球卡如果有特别功能的话，马上就能被下一张扩展时利用了。
