we had expected, the new iphone 5c has a plastic packing and is available in several colours: green, white, blue, pink and yellow.

C. Who
D. As
网友回答
A. Which
B. That
C. Who
(答案→)D. As
解析：句意：正如我们预料的，新的iphone 5c有塑料外壳，有几种颜色：绿色，白色，蓝色，粉红和黄色。这里是非限制性定语从句，as指代后面的主句，在定语从句中as作宾语，翻译成“正如”，which也可以引导非限制性定语从句，但是不能放在句首，that不能引导非限制性定语从句，who不符合句意，选D。
