with ice or not 加不加冰
However, we have already reached temperatures that are in line with other minimum-ice periods, so continued warming is likely not natural.
然而,我们已经达到了与其他最低冰期相一致的温度,所以持续变暖可能是不正常的。
If you must use fish on ice, pick one that is properly store (well-covered with ice, not sitting in a puddle of cold water).
如果你不得不用摆在冰上的鱼,也要选一条经过适当储藏的(用冰好好盖着的,没有泡在一滩冰冷的水里)。
That said, new exchanges are free to introduce contracts that are similar, but not identical, to existing ones-as ICE did so successfully with oil futures.
也就是说,新的交易所可以不受限制的引入此类合约,但不得与现存的雷同——像洲际交易所在石油期货上做的那样。
