问题描述:

He managed to find a boat,___they cound get to the island.(A in which B by which)选哪个?为什么?

选B, 固定短语:by boat

B

应该是A
in a boat

B.
by boat
分为两句
He managed to find a boat
They could get to the island by boat

应该是A
which作为疑问代词,指代前面的a boat,把a boat代入A和B:
In a boat they could get to the island.
By a boat they could get to the island.
By a boat 显然是错的,正确的应该是by boat=in a boat.
与此类似的还有
by car=in a car
by train=in a train
等等

选B by which.
He managed to find a boat,by which they could get to the island.
他设法找到了一只小船,他们能乘小船到岛上。
by which就是by boat,乘船的意思。
"cound"应是"could"吧?

By which
