3个难懂的英语语法问题,请教高手指教十分感谢!
1"The delta between expectations that have been created and the actual reality shows they have a lot more work to do,"
前面的The delta between expectations that have been created这句作何解释?完全看不懂
2like Samsung's Galaxy Gear smartwatch remain too limited features-wise to be anything but niche conversation starters.这句后的be anything but niche conversation starters作何解释,也是看不懂
3same-day will become standard for millions more instant gratification-loving shoppers.

数百万希望下单后马上拿到商品的消费者
