The bird feeder______to keep squirrels from getting to the birdseed.
A．has design
B．is designed
C．was a designer
D．has been designing
参考答案
正确答案：B
解析：根据上下文我们可以推测本句的意思是说饲料桶的用途是为了不让松鼠吃鸟食，“be designed to+动词原形”的意思是“为了……故意设计……”，用在横线上正好合适。另外，作为参考也应记住如果用be designed跟名词形式的话，应该是“be designed for+名词”的形式。(ex. This dictionary is designed for advanced learners of English．)
