His father left his keys in the house,so he had to climb in ____ the window.

问题描述:

His father left his keys in the house,so he had to climb in ____ the window.
A from B cross C across D through
这题我明白为什么选D不选B C 但是不明白为什么不选A

cross和across都是从物体的表面通过
如:Go across the bridge.
through 是从内部穿过
穿过窗户,所以用through.
希望能帮到你,不明白hi我.
